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

Double Reverse Theta *- Centralizer of Rings With Involution
, 2016 Let R be a ring with involution and θ is a mapping of R. It was known that every double reverse θ* - centralizer is a double Jordan θ* - centralizer on R but the converse need not be true . In this paper we give conditions to the converse to be true

Left centralizers on rings that are not semiprime
, 2011 A (left) centralizer for an associative ring R is an additive map satisfying T(xy) = T(x)y for all x, y in R. A (left) Jordan centralizer for an associative ring R is an additive map satisfying T(xy+yx) = T(x)y + T(y)x for all x, y in R.

Centralizers in PBW Extensions
, 2020 In this article we give a description for the centralizer of the coefficient ring R in the skew PBW extension. We give an explicit description in the quasi-commutative case and state a necessary condition in the general case.

Advanced Science, EarlyView.We report a fully wireless, circuit‐free neural stimulator built on a millimetric magneto‐mechano‐electric (MME) cantilever transducer (3 × 10 × 5 mm) with a barium titanate (BTO) piezoelectric ceramic core. Under low‐frequency alternating magnetic fields, the MME cantilever mechanically oscillates, inducing stress on the BTO element and thereby ...
