Zinc selenide optical fibers.
200 μm MRSEC researchers have fabricated the first optical Fibers made from zinc selenide, using a high-pressure Chemical deposition technique invented in the MRSEC. Optical fibers are a cornerstone of modern science and technology, yet remain fundamentally limited by the types of materials from which they can be made. With these new ZnSe fibers, it is now possible to exploit the materials prop...
متن کاملBis(4-nitrophenyl) selenide
In the title compound, C12H8N2O4Se, the Se atom is situated on a twofold rotational axis, so the asymmetric unit contains one half-mol-ecule. In the mol-ecule, the C-Se-C angle is 99.48 (13)°, the two benzene rings are inclined to each other at an angle of 63.8 (1)° and the nitro group is twisted by 15.9 (1)° from the attached benzene ring. In the crystal, mol-ecules are held together through w...
متن کاملAcute hydrogen selenide inhalation.
Acute exposure to selenium hydrochloride resulted in severe dyspnea and a pneumomediastinum in a young healthy man. Pulmonary function tests revealed restrictive and obstructive airways disease. Although the patient's pulmonary function slowly improved, subsequent studies revealed persistent impairment. Therefore, exposure to selenium gas may result acutely in severe coughing and wheezing and m...
متن کاملBis(4-acetylphenyl) selenide
In the title compound, C(16)H(14)O(2)Se, the dihedral angle between the benzene rings is 87.08 (11)°. In the crystal, mol-ecules are linked into layers parallel to the bc plane by inter-molecular C-H⋯O hydrogen bonds.
متن کامل(4-Ethenylphenyl)diphenylphosphine selenide
In the title mol-ecule, C(10)H(17)PSe, the P atom has a distorted tetra-hedral environment resulting in an effective cone angle of 165°. The benzene ring makes dihedral angles of 70.04 (8) and 77.28 (8)° with the phenyl rings, while the dihedral angle between the phenyl rings is 62.95 (8)°. In the crystal, mol-ecules are linked by C-H⋯π inter-actions.
