Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Interface Engineering Remarkably Improves the Stability of Fe‐Based Electrode for Alkaline Water Electrolysis at Industrial Ampere‐Level Current Density

open access: yesCarbon Energy, EarlyView.
Interface engineering improves the stability of iron‐based industrial oxygen evolution catalysts by more than 2000 times at ampere‐level current density. ABSTRACT Iron‐based self‐supported electrocatalysts offer cost‐effective oxygen evolution activity but suffer from severe stability degradation under industrial operation.

Earth’s Earliest Crust

open access: yesElements
The scarcity of rocks preserved from the first billion years (Gy) of Earth’s history hinders our ability to study the nature of the earliest crust. Rare >4.0-Gy-old zircons confirm that felsic crust was present within 500 million years of Earth’s formation.

Biological crusts increase soil microbial biomass and alter bacterial and fungal community compositions under pine restored over ten years in a Pisha sandstone soil

open access: yesFrontiers in Ecology and Evolution
Drylands cover approximately 40% of the global terrestrial area. These regions face multiple challenges, including water scarcity, soil erosion, and declining biodiversity, which significantly undermine soil fertility and ecosystem stability.

Arene Incorporation and Ring Expansion in the Thermal Decomposition of a Divanadium(III) Complex With Four Bridging Methyl Groups

open access: yesChemistry – A European Journal, EarlyView.
Thermolysis of [{VCp*(µ‐CH3)2}2] (Cp* = η5‐C5Me5) in hexane leads to a tetranuclear cube‐type methylidene complex [{VCp*(µ3‐CH2)}4], while in benzenic solvents C6H5R produces the formal insertion of a CH fragment into the six‐membered aromatic ring of a solvent molecule to give trovacene derivatives with η7‐cycloheptatrienyl ligands [VCp*(η7‐C7H6R ...

HARDENING OF CASTING FROM THE CORE SIDE AT VERTICAL CONTINUOUS MOULDING

open access: yesЛитьë и металлургия, 2016
The problem of hardening of fusion in a crystallizer from a core side at vertical continuous molding is solved. It is established that hardening of casting from a core side proceeds in 7–10 time more slowly, than from a crystallizer.
