Morphological Plasticity in a Sulfur-Oxidizing Marine Bacterium from the SUP05 Clade Enhances Dark Carbon Fixation

mBio, 2019
Sulfur-oxidizing bacteria from the SUP05 clade are abundant in anoxic and oxygenated marine waters that appear to lack reduced sources of sulfur for cell growth.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Nanofiber‐Confined 2H‐NbSe2 With a Li2S Activation Interface for 10 C Fast‐Charging Lithium–Sulfur Batteries

EcoEnergy
The uncontrolled shuttle of lithium polysulfides (LiPSs) and sluggish Li2S conversion kinetics critically limits the high‐rate performance of lithium–sulfur (Li–S) batteries.

Effect of sulfur on the polymorphism and reactivity of dicalcium silicate of Portland clinker Efeito do enxofre no polimorfismo e reatividade do silicato dicálcico do clínquer Portland

Cerâmica, 2011
The present study regards the effect of sulfur in dicalcium silicate (Ca2SiO4), a major crystalline phase (20 to 40 wt.%) of the ordinary Portland cement clinker. Dicalcium silicate is also known as C2S (2CaO.SiO2) or belite.

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.

Sulfur-Promoted Decarboxylative Sulfurative Hexamerization of Phenylacetic Acids: Direct Approach to Hexabenzylidyne Tetrasulfides

, 2018
During our experiments aimed at understanding the reaction pathways by which arylacetic acids were oxidatively decarboxylated and condensed with different nucleophiles in the presence of elemental sulfur, these acids have been treated with sulfur powder ...

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 ...

Global sulfur emissions in the 1990s [PDF]

This paper provides global and country by country estimates of sulfur emissions for the early and mid-1990s. Raw estimates are obtained in two ways. For countries with published data we compile that data from the available sources.

Ammoniacal Carbonate Leaching: Effect of Dissolved Sulfur in the Distillation Operation

Acta Chimica Slovenica, 2020
The distillation process in the Ammoniacal Carbonate Leaching technology was studied at bench-scale and on industrial scale. The dissolved sulfur effect in the Product-liquor that feeds to the columns, on the Basic Nickel Carbonate (BNC) properties and ...
