Reversible photo-electrochemical device for solar hydrogen and power generation

Sophia Haussener, Saurabh Yuvraj Tembhurne, Alexandre Dominique M. Cattry, Matthieu Jonin, Mahendra Patel

A reversible photo-electrochemical device operating under concentrated irradiation could offer a stand-alone solution for producing solar fuel (in photo-driven electrolysis mode) and power (in fuel cell mode). This strategy would present the advantage of h ...

Redefining Energy Density for an uniaxial Dielectric Elastomer Actuator

Yves Perriard, Yoan René Cyrille Civet, Jonathan André Jean-Marie Chavanne

The dielectric elastomer actuator (DEA) is a technology known to potentially provide high energy density (0.3 - 0.4 J.cm(-3)). However, in the literature, few demonstrations have been done to evaluate this figure. To well understand the ability of this tec ...

Carbon-Decorated Na3V2(PO4)(3) as Ultralong Lifespan Cathodes for High-Energy-Density Symmetric Sodium-Ion Batteries

Kangning Zhao, Minmin Liu

In this work, several carbon-decorated Na3V2(PO4)(3) materials (NVP@C-750/800/850) are successfully fabricated using a solgel approach and subsequent heat treatment. When NVP@C-800 is used as a cathode, it shows an ultralong cycle life (2000 cycles) at a h ...

Design guidelines for Al-12%Si latent heat storage encapsulations to optimize performance and mitigate degradation

Sophia Haussener, Selmar Rudolf Binder

We provide detailed insight into the growth kinetics of intermetallic layers formed at the interface of molten Al-12%Si with cylindrical encapsulations of 316L stainless steel. This knowledge is relevant for the design and operation of high-temperature lat ...
