Anisotropic Thermal Expansion and Electronic Structure of LiInSe2

open access: yesMolecules, 2022
Optical quality cm-sized LiInSe2 crystals were grown using the Bridgman–Stockbarger method, starting from pure element reagents, under the conditions of a low temperature gradient of 5–6 degrees/cm and a slight melt overheating.

Planar Photonic Crystal Nanocavities with Active Quantum Nanostructures [PDF]

open access: yes, 2004
Extreme photon localization is applicable to constructing building blocks in photonic systems and quantum information systems. A finding fact that photon localization in small space modifies the radiation process was reported in 1944 by Purcell, and ...

Crystal structure of cafenstrole [PDF]

open access: yesActa Crystallographica Section E Crystallographic Communications, 2015
The title compound (systematic name:N,N-diethyl-3-mesitylsulfonyl-1H-1,2,4-triazole-1-carboxamide), C16H22N4O3S, is a triazole herbicide. The dihedral angle between the planes of the triazole and benzene ring planes is 88.14 (10)°. In the crystal, C—H...O hydrogen bonds and weak C—H...π interactions link adjacent molecules, forming one-dimensional ...

The crystal structure of ruthenocene [PDF]

open access: yesActa Crystallographica, 1959
>Dicyclopentadienylruthenium, or ruthenocene, crystallizes in the orthorhombic space group Pnma with a = 7.13, b = 8.99, c = 12.81 A. There are four Ru(C/sub 5/H/sub 5/)/sub 2/ molecules per unit cell. The ruthenium atoms form approximately a face-centered lattice, and the cyclopentadienyl rings lie in an eclipsed configuration with respect to each ...
