Presentation Title: Tailoring Photons from the Sun and Terrestrial Sources with Nanostructures for Energy and Water Nexus
Abstract: Human history has very much depended on how we used heat from the sun and terrestrial sources. Over 90% of human society’s energy input is used by first converting it into heat, and yet only 40% of the total energy input is utilized, significantly lower than what the second law of thermodynamics allows. This presentation will give examples in engineering photons from the sun and terrestrial heat sources with nanostructured materials, aiming to address challenges in energy and water nexus. To lower the cost of solar energy to electricity conversion, we use nanostructures to reduce the thickness of crystalline silicon thin-film solar cells and optically-transparent and thermally-insulating aerogels to replace the vacuum-tube solar collectors in concentrated solar thermal systems. For terrestrial thermal systems, we show that by reflecting infrared radiation back to its emitting heat source, we can significantly improve the efficiency of converting thermally-radiated photons into electricity via thermophotovoltaic devices and the luminous efficiency of incandescent light bulbs. We also demonstrate the ability of boiling water, even generating superheated steam, under unconcentrated sunlight. With properly chosen polymer fiber diameters, we design fabrics so that they are opaque to visible light and yet allow thermal radiation from human body to escape to environment for passively cooling. We conclude the presentation by exploiting the entropy-carrying ability of thermal radiation to convert heat into electricity using pn junctions.

Presentation Title: Coupled Micro/Nanoscale Heat and Mass Transfer in Bio-manufacture
Abstract: Manufacture and processing of novel biological therapeutics becomes increasingly important as it does not only affect the costs of goods but decides the successful delivery to clinics and patients. The challenge is how to preserve the viability, potency and functionality of these complex entities to meet the regulatory requirements using available supply chains. A key to the success is actually the understanding and control of the coupled heat and mass transfer at micro/nanoscales.
In this presentation, three case studies will be presented. (1) cryopreservation of human stem cells, where heat transfer with phase change, freeze concentration and cell membrane transport are all coupled; (2) freeze drying of therapeutic proteins, where freeze concentration induced protein denaturation must be avoided; (3) three dimensional drying of vaccines, where evaporation, Marangoni flow and vitrification are all important to the vaccine potency. One common challenge to bioprocessing is the lack of data, in particular, transport properties. The other is the missing link between physical processing parameters to biological outcome. Both need multidisciplinary research effort on top of better understanding of micro/nanoscale heat and mass transfer.

Presentation Title: Optimizing Complex Systems with AI Enabled PRS Platform
Abstract: A complex system composes of large number of interacting components, which self organize into a non-linear dynamic system. New properties emerge from the complex system and are not directly linked to the property of the individual component. After long-time evolution, the complex system is usually adaptive and robust. Biological systems, synthesized functional materials, internet, social activities and turbulent flows, are examples of complex systems.
Searching for the optimal parameter combination in order to have best system performance is a common challenge in complex systems. For example, how do we guide patient’s body by efficacious combinatorial drug toward a desired phenotype for improving health? Selecting the molecular compositions and determining the concentrations for each composition in material synthesis is another challenge of home in the optimal condition of a complex system.
Assisted by artificial intelligence, we have discovered that the inputs for controlling the complex system are correlated with the endpoint outputs through a Parabolic Response Surface (PRS). With a few calibration tests to determine the coefficients of the quadratic algebraic equation governing PRS, PRS is able to dictate the globally optimized input control parameters. The artificial intelligence enabled Parabolic Response Surface (AI-PRS) platform can be applied to optimize almost all complex systems with large parameter space.

Presentation Title: Transport Processes in the Deposition of Micro/Nanoscale Thin Films
Abstract: Thin films are important in a wide range of practical applications and several techniques are available to obtain high quality films over relatively large regions. This paper focuses on the underlying basic transport processes in the Chemical Vapor Deposition (CVD) system, which is used for coating or for fabricating thin films for electronic and optical devices. The deposited film typically ranges from a few nanometers in thickness to a few microns. The quality of the film, as well as the rate of deposition, are strongly influenced by the transport processes that arise in the reactor. Several complexities are encountered in practical processes and systems, making the experimentation and modeling challenging and involved. These include property variations, complicated regions, combined transport mechanisms, chemical reactions, and intricate boundary conditions.
The chemical reactions and transport mechanisms involved in the deposition are quite different from those in the bulk flow. Thus, modeling has to be carried out at small length scales and then linked to the bulk convective transport. Coupling of the micro/nanoscale domain to the flow and heat transfer in the reactor yields the model that can be used for prediction, process control and optimization. Different numerical models are needed in different domains and appropriate boundary conditions need to be imposed at the boundaries between the different domains. The basic mechanisms may also change from the region near the deposition surface to the flow far downstream, with buoyancy often dominating the flow in some regions and radiation effects dominating near the source. Experimental data, particularly on the chemical kinetics, are critical to the accuracy of the simulation.
The paper presents the fundamental considerations that may be used to accurately simulate these systems for the deposition of materials like silicon, graphene, titanium nitride and gallium nitride. Validation of the numerical model is achieved by comparing with experimental and numerical results on similar systems in the literature. The changes in the material occur mainly at micro- and nanoscale levels, whereas the products being fabricated and the operating conditions are usually at the macro- or engineering scale. Depending on the dimensions, different flow regimes arise, with different analysis and experimentation being needed at different scales. The overall modeling and simulation is employed to determine the quality of the fabricated product, the effect on the environment, process efficiency and optimal conditions. The model is coupled with optimization, which is needed to minimize costs and improve product quality and system performance. Of particular interest are the achievement of high productivity, large percentage of area coverage for deposition and high film thickness uniformity. Of particular interest is multi-objective optimization, since these systems involve several important objective functions, such as those mentioned here. The importance of these results to practical CVD processes for various materials is discussed.

Presentation Title: Numerical Solutions of Nano/Micro Phenomena Coupled with Macroscopic Process
Abstract: Multiphase flow and reactive transport processes in porous media are widely encountered in energy and environment sciences. Typical examples include fuel cells, oil/gas exploitation, CO2 sequestration, thermalchemical storage, etc. The reactive transport processes usually take place at the pore scale (inside the pores or at the interfaces between different constituents), the length scale of which is significantly lower than the length scale of the continuum models based on which transport processes in porous media are usually described. To fill the gap between the two distinct scales, a sets of intrinsic relationships or empirical models are heavily employed to close the continuum-scale models for porous media. However, the validation or accuracy of these relationships/models should be greatly improved to enhance the prediction capacity of the continuum-scale models. For the past 10 years, we devote ourselves to studying at the pore-scale the transport processes in porous media. Advanced pore-scale tools have been developed including reconstruction of realistic porous structures and constituents of porous media, pore-scale numerical models based on the lattice Boltzmann method for multiphase reactive transport in porous media, and upscaling schemes of pore-scale results into continuum-scale models. The transport phenomena of each process at the pore-scale are investigated and the coupled mechanisms between different processes are revealed. Effects of porous structures, size, interface, and constituents on the multiphase flow and reactive transport processes inside the micro/nanosize pores are deeply explored. Based on the pore-scale numerical results and experimental results, it is revealed that some of the intrinsic relationships or empirical models widely adopted in the literature, predict not only quantitatively but also qualitatively wrong results. Based on the pore-scale results, either these relationships /models are improved or completely new relationships/models are proposed to enhance the predication capacity of current continuum-scale models for the transport processes in porous media.

Presentation Title: Nano-Manufacturing for Enhanced Thermal Energy Storage, Cooling & Sensing
Abstract: At the Multi-Phase Flows and Heat Transfer Lab. (MPFHTL) at Texas A&M University (TAMU): we are developing nanotechnology enabled platforms for enhancing cooling, sensing and energy storage (involving both experimental and computational studies). Coupling of thermal and hydrodynamic features during phase change (boiling, condensation) causes spatio-temporal fluctuations of surface temperature at the micro/nano-scales, which are termed as “cold-spots” and can transmit over 60-90 % of the total heat transfer. Using silicon nanofins – cooling was enhanced by ~120 %. Using Carbon-Nanotube (CNT) nanocoatings – cooling was enhanced by 60~300% by leveraging cold-spots and the “nano-fin” effect (“nFE”, which arises due to a combination of enhanced surface area, surface adsorption of solvent molecules, Kapitza resistance / interfacial thermal resistance and thermal inertia/ capacitance effects). Nano-thermocouples (Thin Film Thermocouples/ “TFT”) and diode temperature nano-sensors (DTS) integrated with the nanocoatings enabled the study of thermal chaos and micro/nano-scale fractal structures in boiling (due to thermal-hydraulic coupling). We developed compact condensers with nanocoatings (enhanced heat flux by 100%). In addition, evaporation and condensation experiments performed in nanochannels (lab-on-chip apparatus) demonstrated a significant shift in phase transition temperatures (due to “confined fluid” effect, e.g., in shale rocks for enhanced oil recovery/ EOR). The reliability of Phase Change Materials (PCM) was demonstrated for 1000 cycles of repeated melting and solidification using additives (nucleation promoters).
Specific heat capacity was enhanced by 10∼120% in solvents and solid matrices doped with minute concentration of nanoparticles (i.e., nanofluids and nanocomposites). Experiments for the flow of nanofluids in microchannels showed that the nanoparticle precipitates behaved either as nanofins (enhanced surface area at low concentrations) or caused fouling at high concentrations. These interfacial interactions were demonstrated to dominate the net heat transfer (termed as the “nanofin effect/ nFE”) for micro/nano-scale transport phenomena. The applications include: drug delivery, concentrated solar power/ CSP (thermal energy storage/ TES; thermo-chemical energy storage/ TCES), nuclear power, oil and gas exploration (deep drilling, reservoir engineering and management using nanotracers).
DPN™(Dip Pen Nanolithography™) leverages Scanning Probe Microscopy using microfluidics. Commercial microfluidic devices called “Inkwells™ ” were developed earlier. The next generation microfluidic devices are being developed for DPN (e.g., Fountain Pen Nanolithography, “centiwells”). The applications are in nano-catalysis, bio-nanotechnology, maskless-lithography and nano-sensors for homeland security, bio-security and using N/MEMS based nanocalorimeters for explosives detection (e.g., “nano-nose”/ “nano-tongue”). We invented a gasless process for synthesis of organic nanoparticles (e.g., CNT) under ambient conditions (i.e., in presence of air/ oxygen) and at synthesis temperature of 100°C ∼ 300°C (US Patent 8470285, awarded in 2013).

Presentation Title: Practice Your Scales!
Thermal, Energy, and Bio Nanomaterials for Fast Processes
Abstract: The theory of energy and charge transport is a century old, yet classical and quantum size eﬀects have been exploited usefully in practical materials only for the past two decades, and often with a modest level of success in practice. Many of the remaining challenges involve problems of time and length scales – e.g., faster energy transport processes enabled by new materials that can be manufactured economically at human scales. Success in the large-scale adoption of nanomaterials, with their prevalence of interfaces, will likely depend on deeper fundamental understanding of both interfacial transport in assemblies of nanomaterials over wider time scales and high-throughput manufacturing processes over larger length scales in order to tune their performance and engineer them for desired properties in real applications. For example, individual carbon nanotubes possess extremely high axial thermal conductivity, yet when placed in a composite matrix, the effective thermal properties are quite ordinary. For high-performance cooling applications, single-phase convection is a limited option because of its inability to dissipate ultra-high thermal loads, thus constraining the performance of the host system. With these challenges in mind, this presentation will consider how nanomaterials can be exploited at appropriate engineering scales to improve the performance of realistic thermal and energy storage technologies, particularly those requiring rapid transient response. Carbon nanomaterials for use in fast-charging and discharging electrochemical energy storage devices offer particular promise as scalable, high-performance electrodes, and similar structures show outstanding sensitivity to biological analytes. Moreover, the microstructure of granular assemblies of battery cathode materials will be shown to have a profound effect on charge/discharge speed. As another example, a tunable cooling technology befitting fast transient thermal events will be described. In this system, the rapid depressurization of the working fluid triggers coincident flash boiling and desorption events, thereby achieving very high cooling rates for short periods of time. We anticipate that this technology, when properly controlled, will achieve instantaneous peak cooling efficiencies surpassing those other advanced cooling systems. The presentation will close with a discussion of opportunities to ‘practice our scales’ further in order to enable cost-effective, large-scale production of these technologies.

Presentation Title: Micro-biotransport and its great impact on the survival of living cells and tissues during the cryopreservation process
Abstract: Low temperature has been utilized to keep living biosystems dormant but potential alive for cryopreservation with tremendous scientific and biomedical applications, including cellular-gene therapy, tissue engineering, regenerative medicine, organ transplantation, as well as the conservation of endangered species, etc. However, there is a critical contradiction between the concept of cryopreservation and the experimental findings that the living biosystems can be cryoinjured to death by the cryopreservation process itself. Contrary to popular belief, the challenge to cells during the cryopreservation is not their ability to endure storage at cryogenic temperatures (below -180 ℃); rather it is the lethality associated with micro-biotransport (heat and mass transfer with phase transitions) within an intermediate zone of low temperature (-15 to -60 ℃) that a cell must traverse twice, once during cooling and once during warming. The central theme of this presentation is to report the speaker’s most-recent research work on: (1) micro-biotransport and its great impact on cryoinjury in living cells and tissues during the cryopreservation process; and (2) development of new optimal method, technology/instruments, and bio-MEMS to prevent the cryoinjury and to ensure the survival of living cells and tissues in cryopreservation.

Presentation Title: Development of flexible thermal superconductors
Abstract: This talk is intended to provide a perspective and review of a journey toward a flexible thermal superconductor, which can be bent or twisted, to control heat transfer in heat generating devices of various shapes. The thermal superconductor exploits recent advances in micro pulsating heat pipes, which consists of a liquid-vapor slug-train unit oscillating within a microchannel. It will have a thermal conductivity of 1000 W/mK, 2.5 times higher than copper, and 5000 times higher than current flexible materials, and a thickness of less than 1 mm. Compared to conventional pulsating heat pipes, micro pulsating heat pipes with hydraulic diameters of less than 1 mm have interesting features like orientation independent performance. In addition, several new ideas for thermal performance enhancement in the micro pulsating heat pipes will be presented.

Presentation Title: Nano Liquid Metal as New Generation Electronic Cooling Materials
Abstract: The newly emerging functional materials of room temperature liquid metal and its alloy were initially introduced for the advanced cooling of computer CPU, which later was extended into rather diverse areas such as general high flux or large power cooling, thermal interface material, waste heat recovery, kinetic energy harvesting, printed electronics, 3D printing, biomedical technologies and soft machines etc. Facing that the thermal physical properties of the formerly developed liquid metals were still somewhat limited due to their inherent characteristics encountered, we had ever proposed a new conceptual strategy to revolutionize existing technologies which can be termed as nano liquid metal. Through suspending micro or nanometer-sized particles or fillers into liquid metal, a group of very unconventional capabilities for the fabricated mediums can be enabled. The multi-mode performances of nano liquid metals lie in the outstanding properties of the base fluids of liquid metals such as low melting point, large thermal and electrical conductivity as well as tremendous desirable physical or chemical behaviors. Through taking full use of nanotechnologies, liquid metal can be molded into many outstanding advanced functional materials like highly conductive or compliant coolant, thermal interface grease and phase change soft material etc. According to the specific needs and preparation process, such liquid or composites could exhibit superior fluidic, thermal, electrical, magnetic, chemical, mechanical, and biomedical properties which are much superior than that of conventional coolants or nano materials. This guarantees the versatile adaptabilities of nano liquid metal materials. The present talk presents the basic features of nano liquid metal, its typical fabrication strategies like field induced particle internalization effect, as well as scientific challenges. A group of successful practices and perspective applications of such materials in thermal science area will be introduced. The fundamental micro/nano scale heat transfer mechanisms lying behind will be interpreted.

Presentation Title: Synthesis and solar cell applications of single-walled carbon nanotubes co-axially wrapped with mono- and few-layer boron nitride nanotubes
Abstract: We have synthesized a new coaxial nanotube structure, in which mono- or few-layer hexagonal boron nitride nanotube (BNNT) seamlessly wrap around a single-walled carbon nanotube (SWCNT), and result in an atomically smooth coaxial tube consisting two different materials . TEM-EELS clearly demonstrated the BNNT-SWCNT coaxial structure. We have tried various morphologies of SWCNTs as starting material, e.g. vertically aligned array, horizontally aligned array, suspended SWCNTs, and dry-deposited random network films. We can clearly observe the coaxial structure from originally isolated SWCNTs. Though TEM nano diffraction analysis, we found no correlation between chiral angle of inner SWCNT and outer BNNT for ‘double-walled’ SWCNT-BNNT. We concluded that these are one-dimensional van der Waals heterostructure. From optical observations, such as absorption, Raman and photoluminescence, we can confirm that the SWCNT inside the BN nanotube retain the original optical properties of SWCNT. We have further developed the 1D coating CVD for transition dichalcogenide nanotubes, such as MoS2 nanotube. We can grow MoS2 nanotubes around relatively large diameter SWCNT or SWCNT @BNNT . Applications of these 1D heterostructure material in next generation solar cells [2-4] will be discussed.

Presentation Title: Microscopic Observation of Mass Transfer Obstruction during Gas Hydrate Formation and Decomposition
Abstract: Gas hydrates are crystalline inclusion compounds, where light species molecules are trapped in water cages. Mass transfer during hydrate formation and decomposition plays an important role in gas hydrate production and hydrate flow assurance. Microfocus X-ray CT and synchrotron X-ray CT with sub-micrometer voxel size were used to study the time-resolved evolutions of gas hydrate microstructures during in-situ hydrate formation and decomposition. The full process of hydrate reaction at the phase interface is captured and followed, indicating the diffusion-limiting mechanism of hydrate phase transition. The initial formation of gas hydrate is found to occur at the gas-ice interface in directions of both inward and outward. Once a hydrate shell has formed across the interface, hydrate formation rate is limited by the mass transfer of gas across the hydrate shell. The resistance of mass transfer increases with hydrate shell thickening. The thickness range of hydrate shell at the end of experiments is 40-60 μm, showing a positive correlation with temperature. A hydrate shell growth model on ice sphere surface is developed. Using this model, the gas effective diffusion coefficient and reaction rate constant are obtained. Moreover, the in-situ hydrate decomposition is initiated at the gas-hydrate interface, with the hydrates close to the sand surface largely unchanged. Free water from decomposition gradually accumulates at the decomposing hydrate surface, isolating the hydrates from the gas phase. The very low solubility and diffusivity of gas molecules in water strongly limit the out-diffusion of released gas into the gas phase, resulting in declining decomposition rate as the water layer thickens. A gradient of gas concentration in the water layer is directly observed, indicating a metastable enrichment of gas water. The resulting diffusion-limiting mechanism of in-situ gas hydrate decomposition is of importance for gas hydrate production by depressurization from marine sediments.

He has published over 150 SCI papers on these topics. He developed an improved model to predict the methane hydrate equilibrium in marine sediment environment, and analyzed the mass transfer limitations of gas hydrate decomposition process in gas-rich sedimentary matrix. In addition, he independently designed a novel apparatus for in situ measurement of thermal conductivity of hydrate-bearing sediments, and the model for effective thermal conductivity prediction he improved can suitably predict the measured data. He applies pore network models combined with X-ray computed tomography to investigating the index properties and percolation characteristics of porous media containing hydrates. The triaxial testing apparatus he developed is used to investigate the mechanical behaviors of marine methane hydrate-bearing sediments, demonstrating the effect of exploitation on the stability of hydrate–bearing sediments. His studies provide a basic knowledge for natural gas hydrate exploitation in the South China Sea.

Presentation Title: Nanoengineered Materials for Enhanced Liquid-Vapor Phase Change
Abstract: Liquid-vapor phase change is essential in many thermal energy conversion applications. However, effectively utilizing these processes requires fine manipulation of interfacial transport. In the first part of the talk, we discuss evaporation from ultra-thin nanoporous membranes. Fundamental understanding during evaporation remains limited to date as it is generally challenging to characterize the heat and mass transfer at the interface, particularly when the heat flux is high (> 100 W/cm2). We fabricated ultra-thin (≈ 200 nm thickness) nanoporous (≈ 130 nm pore diameter) membrane devices which reduced the thermal-fluidic transport resistance and accurately monitored the temperature of the liquid-vapor interface. At steady state, we demonstrated high heat fluxes across the interface (≈ 500 W/cm2) with pure evaporation into an air ambient and elucidated the importance of convective transport caused by evaporation itself. In the second part, we discuss condensation with low surface tension liquids. Low surface tension condensates pose a unique challenge since they often form a film, even on hydrophobic coatings. Lubricant infused surfaces (LIS) represent a potential solution, where a lubricant immiscible with the low surface tension condensate is infused into a rough structure on the condenser surface to repel the condensate. We used LIS to demonstrate a 5x improvement in heat transfer for low surface tension fluids compared to filmwise condensation. These works suggest the potential opportunities for significant energy savings in device thermal management, heating and cooling, and power generation.

Presentation Title: Adsorbents related to energy, water, and air
Abstract: Adsorbent is usually in the form of solid with nanoscale porous structures. Adsorption is a rate-controlled process, related to nanoscale heat and mass transfer that highly depends on the boundary conditions. Highly porous adsorbents like silica gel, molecular sieve, activated carbon (fiber), alumina, and MOF could capture gas molecules and release sorption heat through physical adsorption, which promote their widely applications in thermal processes, such as cooling, heating, energy storage, air water harvesting, humidity control, air cleaning and thermal treatment. However, the physical adsorbent is usually limited by its low adsorption capacity and weak adsorption kinetics. Thus it is essential to tailor the structural and thermal properties of the nanoscale pore adsorbent, and even use composite adsorbents, to adapt to real applications to achieve efficient sorption in handling with water vapor, ammonia, CO2 and etc, Reasonable thermal design in device level should be taken into consideration. Here, a strategy to synthesize efficient adsorbents and the principle to select optimal adsorbent-adsorbate working pairs for various adsorption technologies and their typical applications are introduced and discussed. This work shows that adsorbents are closely related to energy, water and air, some promising applications could be realized.

Presentation Title: Raman Spectroscopy Method for Measuring the Thermophysical Properties of Individual Nanoscale Materials
Abstract: The measurement of the thermophysical properties of nanomaterials has been an urgent and key issue of heat transfer research. Electrical methods have been applied to measure the thermal properties of nanowires. The contact methods have common difficulties in sample preparation and are not appropriate for two-dimensional material measurement. This talk will introduce Raman spectroscopy method, as a non-contact method, which has been proved to be a more simple and effective method to measure the thermophysical properties of nanomaterials, both applicable for one-dimensional and two-dimensional materials. Characteristic Raman band shifts of many materials change linearly with temperature. And different materials have different Raman characteristic peaks. Hence, for supported nanomaterials, the temperature of the sample and its substrate can be determined simultaneously. Therefore, the Raman spectroscopy method can be used to determine the thermophysical properties of suspended/supported nanomaterials. We develop several steady-state Raman spectroscopy methods to determine the thermal conductivity and the thermal contact resistance of the nanomaterials. These steady-state methods have already been used to characterize the thermophysical properties as well as the corresponding size effects of carbon nanotube, graphene, and other nanomaterials. The steady-state Raman spectroscopy methods need electric heating or the measurement of laser absorptivity. To avoid them and also to characterize the thermal diffusivity, we propose an unsteady-state method, called the laser flash Raman spectroscopy method. The influence of the laser absorptivity can be eliminated by the nondimensionalized method. The laser flash Raman spectroscopy method has been used to determine the thermal diffusivity of the carbon nanotube, graphene, and other nanomaterials. Nevertheless, the temporal resolution of the laser flash Raman spectroscopy method is limited by the pulse width, which is ∼ 10 ns, cannot match the requirement of supported nanomaterials. We further develop the dual-wavelength laser flash Raman spectroscopy method, separating the heating and probing pulses and controlling the relative delay time. The probing pulse will detect the transient Raman signal of nanomaterials and substrate simultaneously at varied delay time. The temporal resolution can be within 100 ps. The dual-wavelength laser flash Raman spectroscopy method has already be used to measure the thermophysical properties of silicon nanofiber.

Presentation Title: Recent Advances in Nanoscale Thermal Radiation
Abstract: Radiative heat transfer between closely spaced objects can be greatly enhanced at nanoscale separation due to photon tunneling and the enhanced density of states. Furthermore, the interaction of electromagnetic waves with micro/nanostructured materials can potentially modify their far-field radiative properties. Micro/nanoscale thermal radiation concerns both near-field radiative heat transfer between closely spaced objects and the interaction of electromagnetic waves with micro/nanostructured materials that could potentially modify the far-field radiative properties. Graphene and other two-dimensional materials offer possibility to further enhance near-field radiative heat transfer. Nanoscale thermal radiation has promising applications in advanced energy harvesting, nanomanufacturing, thermal control and management, and high-resolution thermal mapping. Significant developments have been made in recent years in the field of micro/nanoscale thermal radiation, both theoretically and experimentally. This presentation will give an overview of the advances and status of this exciting multidisciplinary field. Theoretical challenges and application potential will also be addressed.
