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.

Oxide Interface of Gallium‐Based Liquid Metals: Beneficial Bridge or Hidden Risk?

open access: yesChemistryEurope, EarlyView.
Discussion on oxide interfaces in gallium‐based liquid metals have concentrated on their properties, behaviors, and related applications. However, the molecular mechanisms underlying effects, as well as the differences between the presence and absence of the oxide layer, have been less thoroughly discussed.

A non‐isolated symmetrical design of voltage lift switched‐inductor boost converter with higher gain and low voltage stress across switches

open access: yesIET Power Electronics, EarlyView., 2022
The article discusses the novel topology with high gain and low voltage stress DC‐DC converter based on switched‐capacitor and switched‐inductors for fuel cell and PV applications. The converter performance is analyzed and verified with the hardware prototype (22/400V, 50kHz).

Boron‐Formazanate Complexes as Tunable Redox‐Active Materials for Non‐Aqueous Redox Flow Batteries

open access: yesChemistry – A European Journal, EarlyView.
Boron‐formazanates were investigated as a chemically tunable and electrochemically robust class of redox‐active materials for nonaqueous flow batteries. Electrochemical characterization, coupled with postmortem analysis, uncovers B─F bond cleavage as a key degradation pathway contributing to capacity fade.

Chain Versus Ring: Characterization of a Meta‐Phenylene Ladder Polymer and Its Octameric Macrocycle

open access: yesChemistry – A European Journal, EarlyView.
The synthesis and comprehensive spectral and photophysical analysis of a methyl‐substituted ladder meta‐phenylene macrocycle (MeLMMP) and its polymer analogue (MeLPMP) show that, despite differing topologies (macrocycle vs. polymer), both display nearly identical electronic and photophysical properties due to cross‐conjugation.
