Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A Regularly Interstratified Chlorite/Vermiculite in a Talc-Chlorite Vein [PDF]
A regularly interstratified chlorite/vermiculite was found at the surface of an outcrop of talc-chlorite vein which developed in a serpentinite body at Torika, Saipi-Cho, Nagasaki Prefecture, Japan. The regularly interstratified chlorite/vermiculite, which is regarded as a weathering product of Al-poor Mg-chlorite with IIb polytype on the basis of its ...

Controlled delignification pretreatment tailors the hierarchical porous structure of wood to improve ion transport and create abundant anchoring sites for Ni/Ni(OH)2 catalysts. The optimized electrode shows enhanced mass transfer, increased active site density, and superior overall water‐splitting performance, demonstrating delignification as an ...

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...
