Harnessing Outer Space for Improved Electrocaloric Cooling
Advanced Functional Materials, EarlyView.A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

Thermodynamics equilibrium and non equilibrium of plasma flows
IOP Conference Series: Materials Science and Engineering, 2012 A plasma flow is described using the properties of the entropy function. The plasma flow is a multi-temperature mixture with reactive processes (translation: T for heavy particles, Te for electrons and Tvj for the vibrational temperature of the species j), diffusion and non equilibrium chemical reactions. The entropy rate production is determined for a

Thermodynamics for non-equilibrium pattern formation
AIP Advances, 2011 The second entropy theory for non-equilibrium thermodynamics is used to show that the optimum structure or pattern of a time-dependent system corresponds to the maximum entropy. A formula for the total entropy of convective heat flow is derived.

Photoswitchable Conductive Metal–Organic Frameworks
Advanced Functional Materials, EarlyView.A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.

Advanced Functional Materials, EarlyView.This study examines the surface characteristics of AlInP (001), crucial for advanced solar cells and photoelectrochemical devices. Using theoretical modeling and experiments, it identifies how phosphorus‐rich and indium‐rich surfaces create mid‐gap states that pin the Fermi level and influence ultrafast electron dynamics.
