In Situ Programmable Modulation of Hydrogel Stiffness for Stage‐Adaptive Bone Regeneration

Advanced Science, EarlyView.
Near‐infrared (NIR) irradiation triggers Ca2+ release from thermoresponsive nanocarriers, enabling in situ stiffening of an adaptive hydrogel from a soft to a stiff state, thereby sequentially supporting mesenchymal stromal cell stemness and osteogenic differentiation for stage‐adaptive bone regeneration.

Further Evidences for the Sulfur Spillover on Carbon: Thermodynamic Aspects and Effects on Li‐S Solid‐State Batteries

Advanced Science, EarlyView.
ABSTRACT This study investigates sulfur spillover, the spontaneous and rapid spread of sulfur over carbon surfaces at ambient temperature. The process is studied by small‐angle X‐ray scattering (SAXS), X‐ray radiography, and microcalorimetry from which a number of physicochemical properties are derived.

High‐Entropy Engineering and External Magnetic Field Modulation Synergistically Enhance the H2S Sensing Performance of Rare‐Earth Perovskite Ferrites

Advanced Science, EarlyView.
A novel high‐entropy perovskite oxide, (Gd0.2Tb0.2Dy0.2Ho0.2Er0.2)FeO3, was successfully synthesized for advanced hydrogen sulfide gas detection. By synergistically coupling high‐entropy‐induced local lattice distortion with weak magnetic field modulation, the tailored material generates abundant active sites. This innovative dual strategy dramatically

The sulfur cycle.

Science (New York, N.Y.), 1972
Even granting our uncertainties about parts of our model of the sulfur cycle, we can draw some conclusions from it: 1) Man is now contributing about one half as much as nature to the total atmospheric burden of sulfur compounds, but by A.D. 2000 he will be contributing about as much, and in the Northern Hemisphere alone he will be more than matching ...

The Sulfur Cycle

1980
The geochemistry of sulfur is to a great extent affected by the biosphere. Living organisms transform sulfur from one oxidation state to another, thus changing the chemical properties of sulfur compounds and their distribution in the atmosphere, soils, waters and sediments.
