A temperature-dependent phase transformation of (E)-2-[(4-chloro-phen-yl)imino]-ace-naphthylen-1-one. [PDF]

open access: yes, 2017
The crystal structure determination based on 90 K data of the title imine ligand, C18H10ClNO, revealed non-merohedral twinning with three twin domains. In our experience, this is an indication of an ordering phase transition.

The Crystal Structure of Monovalent Streptavidin. [PDF]

open access: yes, 2016
The strong interaction between streptavidin (SA) and biotin is widely utilized in biotechnological applications. A SA variant, monovalent SA, was developed with a single and high affinity biotin-binding site within the intact tetramer.

Photonic Crystal Laser Accelerator Structures [PDF]

open access: yes, 2003
Photonic crystals have great potential for use as laser-driven accelerator structures. A photonic crystal is a dielectric structure arranged in a periodic geometry.

[1,1′-Bicyclohexane]-1,1′-diol

open access: yesIUCrData, 2023
The title compound, C12H22O2, is a symmetric diol derived from the pinacol coupling of cyclohexanone. The asymmetric unit contains three complete molecules. The cyclohexane moieties adopt chair conformations.

Linear, diatomic crystal: single-electron states and large-radius excitons [PDF]

open access: yes, 2008
The large-radius exciton spectrum in a linear crystal with two atoms in the unit cell was obtained using the single-electron eigenfunctions and the band structure, which were found by the zero-range potential (ZRP) method.

Continuous-wave operation of electrically pumped, single-mode, edge-emitting photonic crystal Bragg lasers [PDF]

open access: yes, 2007
The authors demonstrate an electrically pumped, single-mode, large-area, edge-emitting InGaAsP/InP two dimensional photonic crystal Bragg laser operating in continuous-wave condition.

Crystal structure and high-field magnetism of La2CuO4 [PDF]

open access: yes, 2006
Neutron diffraction was used to determine the crystal structure and magnetic ordering pattern of a La2CuO4 single crystal, with and without applied magnetic field.

Pressure-induced amorphization, crystal-crystal transformations and the memory glass effect in interacting particles in two dimensions [PDF]

open access: yes, 2005
We study a model of interacting particles in two dimensions to address the relation between crystal-crystal transformations and pressure-induced amorphization.

Two-dimensional phononic-photonic bandgap optomechanical crystal cavity [PDF]

open access: yes, 2014
We present the fabrication and characterization of an artificial crystal structure formed from a thin-film of silicon which has a full phononic bandgap for microwave X-band phonons and a two-dimensional pseudo-bandgap for near-infrared photons.
