Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

Advanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.

Polyoxometalates as a precursor in one-pot synthesis of MoS2-V2O5@CC for electrocatalytic hydrogen evolution

Polyoxometalates
Polyoxometalates (POMs) are ideal preassembled platforms for constructing transition metal catalysts because they are rich in oxygen and transition metal elements. In contrast to traditional methods for preparing V2O5/MoS2 composite catalysts, the method

One Step Hydrothermal Synthesis of Ni-MoS2-RGO Bifunctional Electrocatalysts for HER and OER

International Journal of Electrochemical Science, 2021
Pure MoS2 and Ni-MoS2-RGO were prepared by a one-step hydrothermal approach. The result indicated that intensity of XRD diffraction peaks for MoS2 increase slightly as with the increase of RGO content.

Magnetic Control of Chiral Hybridized Phonon Magnetic Moments in Ferrimagnets Fe2‐xZnxMo3O8

Advanced Functional Materials, EarlyView.
Helicity‐resolved magneto‐Raman spectroscopy reveals magnetic control of chiral phonon magnetic moments in polar ferrimagnet (ZnxFe2−xMo3O₈). Large spontaneous zero‐field phonon splittings, selective phonon–magnon coupling, and asymmetric Zeeman responses demonstrate that phonon chirality is governed by magnon‐phonon coupling and magnetization.
