AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Aqueous zinc metal batteries with mild acidic electrolytes are considered promising candidates for large-scale energy storage. However, the Zn anode suffers from severe Zn dendrite growth and side reactions due to the unstable interfacial pH and the absenc ...
Designing solid electrolytes for all-solid-state-batteries that can withstand the extreme electrochemical conditions in contact with an alkali metal anode and a high-voltage cathode is challenging, especially when the battery is cycled beyond 4 V. Here we ...

The perovskite-type mixed oxide La0.3Sr0.55Ti0.95Ni0.05O3-delta (LSTN) is demonstrated to exhibit the remarkable property of structural regeneration, where Ni can be reversibly exsoluted from the host perovskite lattice resulting in a regenerable Ni cataly ...
In this paper, the degradation mechanisms of the ceramic and the metal in Titanium/Zirconia pairs for biomedical applications were analyzed. To do that, an experimental set-up with well-controlled mechanical and chemical conditions was used based on a unid ...
Aqueous Zn-ion batteries, which are being proposed as large-scale energy storage solutions because of their unparalleled safety and cost advantage, are composed of a positive host (cathode) material, a metallic zinc anode, and a mildly acidic aqueous elect ...

In searching for a suitable semiconductor material for hydrogen production via photoelectrochemical water splitting, alpha-Fe2O3 received significant attention as a promising photoanode due to its band gap (similar to 2.1 eV), good stability, low cost, and ...
Dendrite formation limits the cycle life of lithium and sodium metal anodes and remainsa major challenge for their integration into next-generation batteries, even whenreplacing the liquid electrolyte by a solid electrolyte. Voids forming in solid metal an ...
The electrodeposition of stainless steel-like FeCrNi alloys for miniaturised devices is appealing as it would allow combining excellent material properties (e.g. corrosion resistance, hardness, biocompatibility) at low-cost. However, conventional baths oft ...
We demonstrate ultralow leakage current AlGaN/GaN Schottky-barrier diodes (SBDs) based on a 3-D anode contact. In contrast to conventional AlGaN/GaN SBDs, this new device forms a Schottky contact directly to the 2-D electron gas (2-DEG) at the sidewalls of ...
