The Nukiyama Memorial Award<\/a> has been established by the Heat Transfer Society of Japan to commemorate outstanding contributions by Shiro Nukiyama as an excellent heat transfer scientist. Nukiyama addressed the challenges of boiling phenomena and published a pioneering paper which clarified these phenomena in the form of the Nukiyama curve (boiling curve). This epoch-making work was done in 1930s, when heat transfer research was in an early stage and Nukiyama himself was young, under forty years old. The Nukiyama Memorial Award is bestowed to a scientist under\/ about fifty years of age, once every two years in the field of Thermal Science and Engineering. The recipient of the Nukiyama Memorial Award 2026 is Prof. Masahiro Nomura.

\r\nAbstract<\/strong>
\r\n
\r\nHeat conduction control in a semiconductor membrane by nanostructuring will be discussed from the viewpoint of photonics. We classify the systems by similarity, difference, and hybridization of phonons and phonons, and explain characteristic thermal phonon transport in each system. Prospects for thermal phonon engineering will be also discussed.
\r\n
\r\nLight propagation in ray optics and thermal phonon transport at the nanoscale are similar due to ballisticity. The characteristic propagation of light and mechanical vibrations in band-engineered periodic structures, i.e. photonic and phononic crystals, derives from the wave properties of electromagnetic and elastic waves. Some recent work on the control of heat conduction by well-designed nanostructures has been taken up to discuss how we can design nanostructures to control heat transport more effectively by considering the similarity and difference of photons and thermal phonons [1]. The ballistic behavior of phonons in their mean free path (MFP) allows advanced heat flux control such as directional heat flux and heat focusing. This thermal phonon behavior is similar to ray optics and is therefore named \u201cRay phononics\u201d [2]. The selection of phonon k-vector direction by aligned nanoholes formed in a membrane result in the formation of directional heat flux. The directional heat flux is maintained within the MFP of thermal phonons. The interaction and hybridization of photons and phonons are also interesting and will lead to new functionality. Phonons can control the emission of a single photon from a quantum dot embedded in a high-Q optical micro\/nanocavity [3, 4].
\r\n
\r\nRegarding hybridization, phonons can travel faster by four orders of magnitude by shaking hands with photons: forming surface phonon polaritons (SPhPs) leading to the enhancement of thermal conduction in thin dielectric membranes. This dramatic change in thermal energy transport property by SPhPs opens new possibilities for thermal management in thin membranes [5]. The hydrodynamic behavior of phonons is an example of a different transport phenomenon that is a phenomenon rarely observed in optics. The collective behavior, which exists in electronic and phononic systems due to interaction, of phonons provides interesting thermal transport such as phonon Poiseuille flow [6]. We demonstrate the first thermal Tesla valve [7], thermal diode, as an example of applications.

\r\nAbstract<\/strong>
\r\n
\r\nNature is fascinating, enchanting, and often mysterious. The beauty of softly falling snow, the warmth of the Sun on cold wintry days, intoxicating evening breeze in the summer, and raindrops falling on our roofs are among the many lovely ways in which we see our natural world. Nature can also be bewildering and terrifying. This includes natural events ranging from earthquakes, hurricanes, tsunamis, and tornadoes that can cause widespread destruction to droughts, floods, mudslides, forest fires, snowstorms, and many other extreme weather conditions that can affect millions. Nature has amazing power and can disrupt the lives of all those who inhabit this lovely planet. Interestingly, thermal energy transport is behind much of what we observe in Nature. We receive much of our energy from the Sun and reject energy to space, resulting in an annual periodic variation in heat transfer to and from the Earth. An energy imbalance would lead to global warming, which has been a growing concern in recent years. Temperature and moisture concentration differences in Earth\u2019s gravitational field drive most of the flows that we observe in the atmosphere and in the lakes and oceans. Temperature differences also generate flows that give rise to Earth\u2019s magnetic field that deflects the stream of charged particles from the Sun and helps preserve our atmosphere. Heat transfer is also behind the movement of tectonic plates, earthquakes and volcanoes. Wildfires are obviously driven by combustion and are thus closely linked with heat transfer. Similarly, heat transfer plays a critical role in determining our weather and climate. All living creatures are affected by thermal energy, and evolution has equipped them with the means to cope with weather extremes. We are familiar with plants and trees bending to catch greater amount of sunlight. The thermal cycle experienced by lakes and rivers as well as hot springs and geysers also depend on the thermal transport. These and many other natural phenomena that we enjoy or are concerned about have heat transfer as a primary driver.
\r\n
\r\nSimilarly, many technological advancements have been driven by heat transfer processes. From heating, air conditioning, cars and airplanes to manufacturing, food processing, and thermal management of electronic system, heat transfer is at the very core of the systems involved. We cannot talk about data centers without discussing their cooling. Thermal processing is critical in
\r\na wide range of materials like food, polymers and steel. Power plants as well as renewable energy systems are largely driven by heat transfer processes. In many cases, we have a strong coupling between natural processes and technology, for instance, in heat rejection, thermal pollution and climate change. Data center cooling could be linked with environmental conditions for more effective thermal management. Many of the advancements in new and emerging materials and devices are also driven by thermal transport processes. Many other important processes and systems can be mentioned where thermal energy transport is critical to the quality of the resulting product and process efficiency. This talk focuses on the wide-ranging impact of heat transfer in driving natural phenomena as well as technological innovation and advancement. The basic mechanisms by which heat transfer drives the flows in nature or sustains various systems in technology are discussed. The link between natural phenomena and technology is examined with respect to areas like climate change, thermal pollution, energy extraction, safety and sustainability. Nature-based design and optimization are critical in many cases and are discussed.
