Continuous‐Flow Microfluidic Synthesis Enhances C2+ Selectivity for Cu2O Catalysts
Advanced Science, EarlyView.Microfluidic devices are used to prepare Cu2O nanoparticles under laminar flow conditions, which exhibit enhanced selectivity in the CO2‐to‐C2+ reaction due to their nanoporosity and high defect concentration. Cu2O prepared using standard solution methods displays decreased CO2‐to‐C2+ selectivity due to the absence of similar properties. Altogether, we

Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking
Advanced Science, EarlyView.The removal of O lattice atoms by environmental H2 at the surface of Fe3O4 results in Fe enrichment, driving the inward diffusion of Fe cations into the bulk. Through hopping between unoccupied and initially occupied sites, cation diffusion triggers a spatially displaced reaction‐transformation and drives subsequent dynamic phase transformations and ...

A mathematical description of fossilization
Royal Society Open ScienceFossils constitute an inestimable archive of past life on the Earth. However, the stochastic processes driving decay and fossilization and overwhelmingly distorting this archive, are challenging to interpret. Consequently, concepts of exceptional or poor

Fossil Collection at the Zoology Museum of the University of Concepción: enhancing understanding of Chile's past biodiversity [PDF]
Biodiversity Data JournalThe digital inventory of paleontological material stored in Chilean museums is highly relevant as it increases accessibility to information, both locally and over long distances, while reducing wear and tear on specimens caused by physical manipulation ...

Two‐Dimensional Quaternary Alloys of (RuMoVNb)Se2 for Superior Hydrogen Evolution Reaction Catalysis
Advanced Science, EarlyView.Composition‐tuned (RuMoVNb)Se2 quaternary alloy nanosheets are synthesized via colloidal reactions. Incorporation of Ru into (MoVNb)Se2 ternary alloys results in more metallic electronic structures and significantly enhances their electrocatalytic activity for the hydrogen evolution reaction (HER) under alkaline, acidic, and neutral conditions.
