To be able to determine the elemental composition and morphology of individual nanoparticles consisting of no more than a dozen or so atoms that weigh a few zeptograms (10(-21) g) is but one of the attainments of modern electron microscopy. With slightly larger specimens (embracing a few unit cells of the structure) t…

Cyanide-functionalized mesoporous silica SBA-15 (CN/SBA-15) with pore diameters larger than 6 nm has been prepared by a one-pot synthesis. The structure of CN/SBA-15 is affected by the amount of the functional silane 2-cyanoethyltriethoxysilane (CTES) and the conditions of co-condensation in the acidic aqueous solutio…

For wetland soil studies, it would be desirable to estimate soil redox status and its effect on element translocations based on diagnostic redoximorphic features. However, their identification and interpretation is often complicated and require a regional calibration. This study was conducted (i) to determine the rela…

Photochromic performance of diarylethene single crystals was controlled by crystal engineering using non-covalent aromatic-aromatic interactions as the directional intermolecular force. A diarylethene derivative with two pentafluorophenyl groups, 1,2-bis(2-methyl-5-pentafluorophenyl-3-thienyl)perfluorocyclopentene (1a…

Results of the electrical conductivity study of highly textured, ultrathin (15 nm) cubic yttria-stabilized zirconia (YSZ) thin films are presented for the first time. A nanoscale effect that results in exceptionally high ionic conductivity at moderate temperatures is detected in films less than 60 nm thick. The conduc…

Bimodal porous carbons with both micropores and meso- or macropores were selectively synthesized by an colloidal crystal-templating process. The opal templates exclusively contributed to the formation of meso- and macropores in carbons. The electrical double-layer capacitance per surface area of the templated porous c…

K6Cd4Sn3Se13 forms in superheated water and has a polar open-framework structure that is based on an octahedral topological motif. It forms from the polymerization of a single [Cd4Sn3Se13]6− cluster which formally derives from a [Cd4Sn4Se17]10−via elimination of one [SnSe4]4− anion. K6Cd4Sn3Se13 exhibits facile ion-ex…
