Metal Carbide Additives in Graphite‐Silicon Composites for Lithium‐Ion Batteries

ChemElectroChem, Volume 10, Issue 21, November 2, 2023., 2023
Graphite‐silicon composites for batteries: Molybdenum and Chromium Carbides are used as additives to stabilize graphite/silicon composites. Spark plasma sintering technology is used to sinter the electrode powders. The presence of molybdenum or chromium carbides promotes the performance of C/Si electrodes in lithium cells, improving the cycling ...

Insights into the High Activity of Ruthenium Phosphide for the Production of Hydrogen in Proton Exchange Membrane Water Electrolyzers

Advanced Energy and Sustainability Research, Volume 4, Issue 11, November 2023., 2023
Herein, RuP with high activity for the hydrogen evolution reaction in acidic electrolyte comparable to state‐of‐the‐art Pt‐based catalyst is reported. A pure, stoichiometric RuP is synthesized by a simple one‐pot approach. RuP exhibits an impressive low overpotential of 36 mV at 10 mA cm−2 in rotating disk electrode.

High Performance and Durable Anode with 10‐Fold Reduction of Iridium Loading for Proton Exchange Membrane Water Electrolysis

Advanced Energy Materials, Volume 13, Issue 23, June 16, 2023., 2023
A double perovskite catalyst Sr2CaIrO6 reduces the amount of iridium significantly in the anode for proton exchange membrane water electrolyzers (PEMWE). High performance and durability can be achieved with only 0.2 mgIr cm‐2. Anodes with low iridium loadings can be established as the new state of the art in PEMWEs making green hydrogen more ...

Ecological constraints on highly evolvable olfactory receptor genes and morphology in neotropical bats

Evolution, Volume 76, Issue 10, Page 2347-2360, October 2022., 2022
Abstract Although evolvability of genes and traits may promote specialization during species diversification, how ecology subsequently restricts such variation remains unclear. Chemosensation requires animals to decipher a complex chemical background to locate fitness‐related resources, and thus the underlying genomic architecture and morphology must ...

Policy Diffusion Through Multiple Streams: The (Non‐)Adoption of Energy Conservation Building Code in India

Policy Studies Journal, Volume 50, Issue 3, Page 641-669, August 2022., 2022
Although the diffusion of policy innovations can promote sustainability, how this process can be accelerated remains unclear. I address this gap by conceptualizing policy transfer and policy diffusion using the multiple streams framework (MSF) and developing hypotheses to connect them.
