A micro-sheet anatase TiO(2) single crystal photocatalyst with a remarkable 80% level of reactive {001} facets was synthesized via a microwave-assisted hydrothermal route involving titanium tetrafluoride and a tetrafluoroborate-based ionic liquid.

Direct liquid crystal templating from non-ionic polyoxyethylene surfactants has been utilised to produce well-defined birefringent films of nanostructured cadmium telluride films which displayed good optical properties as evidenced by UV/VIS reflectance spectroscopy.

The diffusion of ions in an ionic liquid crystal exhibiting a bicontinuous cubic liquid-crystalline phase has been investigated by NMR spectroscopy in order to examine the behaviour of ions in an ordered nanostructure.

Liquid Crystal Phase Transitions of Monodisperse and Bidisperse Suspensions of Rodlike Colloidal Virus A dissertation presented to the Faculty of the Graduate School of Arts and Sciences of Brandeis University, Waltham, Massachusetts by Kirstin Rachael Purdy We experimentally study the role of steric and electrostatic interparticle interactions in monodisperse and bidisperse suspensions of rodl...

Accurate electron densities and X-ray form factors of Li, Be, F and their ions have been calculated. Electron correlation, crystal fields and ionic charge transfer change the form factors by up to a few percent, mainly in the range of sin 0 /k < | Ä " 1 . Although electron correlation and crystal fields are small perturbations, their effects on the density and form factor are not additive. Dens...

The recently solved crystallographic structures for the A(2A) adenosine receptor and the beta(1) and beta(2) adrenergic receptors have shown important differences between members of the class-A G-protein-coupled receptors and their archetypal model, rhodopsin, such as the apparent breaking of the ionic lock that stabilizes the inactive structure. Here, we characterize a 1.02 mus all-atom simula...

The removal of crystal violet from aqueous solution by NiFe2O4 magnetic nanoparticles treated with sodium dodecyl sulfate was investigated. The modified magnetic nanoparticles were prepared by chemical reaction of a mixture of Ni+2 and Fe+3 ions mixture in aqueous solution at the presence of ammonia and then sodium dodecyl sulfate was utilized as an ionic surfactant to modified the obtained mag...

The crystal packing of the title compound, C(6)H(11)N(2)O(+)·I(-), can be described as inter-calated layers lying parallel to (010), with the iodide ions located between the cations. A weak intra-molecular C-H⋯O hydrogen bond occurs within the cation. In the crystal, inter-molecular O-H⋯I hydrogen bonds result in the formation of a three-dimensional network and reinforce the cohesion of the ion...

Structure is the most fundamental characteristics of a material. X-ray crystallography allows one to determine how atoms are arranged in a molecule and how molecules pack into a crystal. However, it requires a high-quality crystal sample, which is time consuming to prepare and often impossible under extreme conditions. Theory has been playing a significant role in understanding crystal structur...

Hydrothermal investigations in the high silica region of the Na20-Y 203-Si60 15 system, carried out in a search for novel fast-ion conductors (FIC's), yielded the new compound trisodium yttrium hexasilicate, Na3 YSi60 15 • Single-crystal X-ray methods revealed that Na3 YSi60 15 crystallizes in space group Ibmm, has lattice constants a = 10.468 (2), b = 15.2467 (13) and c = 8.3855 (6) A, Z = 4, ...
