Ecological constraints on highly evolvable olfactory receptor genes and morphology in neotropical bats. [PDF]
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 ...

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

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.

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 ...

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.

5‐Hydroxymethylfurfural (HMF) is synthesized in one step from glucose using tandem catlysts based on several metal organic framework catalysts and a polyoxometalate adding separately or by encapsulation. In both cases, the highest performance is obtained with MIL‐101(Cr) with high HMF yields of around 40%.

Ensuring the supply of electricity in a reliable and safe way is not an easy task, especially when considering renewable and clean energy generated with wind turbines given the intermittency or variability of the wind; also considering different time horizons increases complexity. Mexico has great potential for wind energy in the Eastern region and, to

Resumen El entorno alimentario es un factor importante que contribuye a las dietas poco saludables en la niñez y, por tanto, a las crecientes tasas de obesidad. Los países de Latinoamérica han recibido el reconocimiento internacional por su liderazgo en la implementación de políticas dirigidas a distintos aspectos del entorno alimentario.

Resumen Aunque se han hecho avances en el desarrollo y aplicación a gran escala de intervenciones eficaces contra la obesidad infantil, los retos siguen siendo importantes. Nuestro objetivo era comprender las causas del éxito de Estados Unidos y los países latinoamericanos en la implementación de políticas y programas (PYP) contra la obesidad e ...
