DOI: 10.1002/jrs.5236

Abstract: We report a comparative study of rigid-layer Raman-active modes in N-layer transition metal dichalcogenides. Trigonal prismatic (2Hc, such as MoSe2, MoTe2, WS2, and WSe2) and distorted octahedral (1T', such as ReS2 and ReSe2) phases are… read more here.

DOI: 10.1021/acsnano.2c11240

Abstract: Resonance Raman spectroscopy is an efficient tool for multiplex imaging because of the narrow bandwidth of the electronically enhanced vibrational signals. However, Raman signals are often overwhelmed by concurrent fluorescence. In this study, we synthesized… read more here.

DOI: 10.1021/jacs.3c11334

Abstract: The surface oxidation states of the metal electrodes affect the activity, selectivity, and stability of the electrocatalysts. Oxide formation and reduction on such electrodes must be comprehensively understood to achieve next-generation electrocatalysts with outstanding performance… read more here.

DOI: 10.1039/d0tc04101g

Abstract: The Raman-active phonon modes of β-Ga2O3 in two O isotope compositions are studied by theory and experiment. Raman modes dominated by different, inequivalent O lattice sites were identified and can be used for the investigation… read more here.

DOI: 10.1089/ast.2021.0170

Abstract: Anthraquinones are a family of natural products with useful bioactivity and optical properties. An anthraquinone called parietin is produced by extremophiles to protect against solar ultraviolet B radiation, so it is a potential biosignature in… read more here.
