Hydrogen (H2) Recovery From Hydrogen Sulfide (H2S): Current Technologies, Challenges, and Future Outlook

Advanced Science, EarlyView.
ABSTRACT Hydrogen sulfide (H2S) can be transformed into hydrogen (H2) through several chemical and catalytic processes, offering a promising route for both waste treatment and clean H2 production. This colorless, flammable, and toxic gas is found abundantly in swamps, volcanoes, hot springs, sewages, other natural gas fields, and even in refineries and

Electrostatic Potential Complementarity for Thickness‐Tolerant Cathode Interlayers in High‐Efficiency Organic and Tandem Solar Cells

Advanced Science, EarlyView.
Two model molecules — trimesic acid (TMA) and phloroglucinol (PG) — with opposite central electrostatic potential (ESP) distributions are employed to elucidate how molecular electrostatic interactions regulate the cathode interlayer (CIL) PDINN. Electrostatic potential complementarity is revealed as the intrinsic origin of thickness sensitivity in CILs,

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,
