Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Volcanically driven Hg–C–S cycling and climate change across the Early Permian Artinskian warming

Communications Earth & Environment
Climate change and driving mechanisms of the Late Paleozoic Ice Age, an ideal analogue to the present-day global change, remain controversial. Here we propose a volcanic carbon–sulfur radiative forcing mechanism by investigating the Lower Permian ...

Deep-sea in situ and laboratory multi-omics provide insights into the sulfur assimilation of a deep-sea Chloroflexota bacterium

mBio
Chloroflexota bacteria are abundant and globally distributed in various deep-sea ecosystems. It has been reported based on metagenomics data that two deep-sea Chloroflexota lineages (the SAR202 group and Dehalococcoidia class) have the potential to drive

Integration of Low‐Voltage Nanoscale MoS2 Memristors on CMOS Microchips

Advanced Functional Materials, EarlyView.
This article presents the first monolithic integration of nanoscale MoS2‐based memristors into the back‐end‐of‐line of foundry‐fabricated CMOS microchips in a one‐transistor‐one‐resistor (1T1R) architecture. The MoS2‐based 1T1R cells exhibit forming‐free, nonvolatile resistive switching with ultra‐low operating voltages, low cycle‐to‐cycle variability ...

The potential for coupled organic and inorganic sulfur cycles across the terrestrial deep subsurface biosphere

Nature Communications
Organosulfur compounds (OrgS) are fundamental components of life’s biomass, yet the cycling of these compounds in the terrestrial deep subsurface, one of Earth’s largest ecosystems, has gone relatively unexplored.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Intermittent cyanobacterial accumulation reshapes water column sulfur cycling and favors sulfur-oxidizing denitrifiers in freshwater lake mesocosms

Ecotoxicology and Environmental Safety
Recent studies have established that cyanobacterial bloom biomass (CBB) decomposition critically drives sulfur cycling in the water column of shallow lakes.
