We report the structural and optical properties of molecular beam epitaxy (MBE) grown 2-dimensional (2D) material molybdenum diselenide (MoSe2) on graphite, CaF2 and epitaxial graphene. Extensive characterizations reveal that 2HMoSe2 grows by van-der-Waals epitaxy on all 3 substrates with a preferred crystallographic orientation and a Mo:Se ratio of 1:2.
The title compound, NpCuSe(2), is the first ternary neptunium transition-metal chalcogenide. It was synthesized from the elements at 873 K in an evacuated fused-silica tube. Single crystals were grown by vapor transport with I(2). NpCuSe(2) crystallizes in the LaCuS(2) structure type and can be viewed as a stacking of layers of CuSe(4) tetra-hedra and of double layers of NpSe(7) monocapped trig...
Measurements of titanium diselenide differentiate between the material's optical phonons and charge-density-wave excitations, showing use tabletop extreme ultraviolet spectroscopy to probe dynamics.
In the title compound, C(14)H(12)Br(2)Se(2), the Se-Se bond length [2.3034 (9) Å] is similar to those in diphenyl diselenide [2.3066 (7) and 2.3073 (10) Å] and shorter than that in 1,8-diselenona-phthalene [2.0879 (8)Å]. The mol-ecule adopts a classical gauche conformation.
Thin films of copper indium diselenide (CIS) were prepared by chemical bath deposition technique onto glass substrate at 60C. The studies on composition, morphology, optical absorption, electrical conductivity and structure of the films were carried out. Characterization includes X-ray diffraction (XRD), Scanning electron microscopy (SEM), Atomic force microscopy (AFM), Energy dispersive x-ray ...
A diselenide containing fluorescent probe based on a fluorescein scaffold for thiols was developed. The fluorescent probe exhibited rapid response, high selectivity and reversibility. Confocal fluorescence microscopy was used to visualize the redox changes mediated by thiols and reactive oxygen species in living HeLa cells.
Pass them on! Dithiobutylamine immobilized on a resin is a useful reagent for the reduction of disulfide bonds. Its ability to reduce a disulfide bond in a protein is enhanced greatly if used along with a soluble strained cyclic disulfide or mixed diselenide that relays electrons from the resin to the protein. This electron-relay catalysis system provides distinct advantages over the use of exc...
