Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

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.

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Microbial Diversity Across Chemolithotrophic and Phototrophic Biofilms in Cold Sulfur Springs

MicrobiologyOpen
Sulfur‐rich environments host specialized microbial communities that drive key biogeochemical processes, particularly sulfur cycling. While sulfur‐oxidizing microbiota from hydrothermal vents and volcanic systems are well studied, microbial communities ...

Sulfur and carbon cycling in organic-rich marine sediments [PDF]

, 1985
Nearshore, continental shelf, and slope sediments are important sites of microbially mediated carbon and sulfur cycling. Marine geochemists investigated the rates and mechanisms of cycling processes in these environments by chemical distribution studies,

Geochemical evidence for cryptic sulfur cycling in salt marsh sediments [PDF]

Cryptic sulfur cycling is an enigmatic process in which sulfate is reduced to some lower-valence state sulfur species and subsequently quantitatively reoxidized; the rate and microbial energetics of this process and how prevalent it may be in the ...

Evidence for Microbial Carbon and Sulfur Cycling in Deeply Buried Ridge Flank Basalt [PDF]

, 2012
Sediment-covered basalt on the flanks of mid-ocean ridges constitutes most of Earth's oceanic crust, but the composition and metabolic function of its microbial ecosystem are largely unknown.

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.

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.
