Abstract Polymer blended materials such as polyamide 6 (PA6)/polypropylene (PP) blends have received considerable attention in recent years. To improve the compatibility of PA6 and PP, compatibilizers like maleic anhydride‐ g ‐polypropylene (MPP) are often added. In addition, organically modified montmorillonite (MMT)…

We report on photocurrent switching based on photoisomerization for the nondestructive readout of photochromic optical memory. The photoisomerization of a diarylethene (DAE) memory layer switched the photocurrent generated in a light-absorbing phthalocyanine layer upon irradiation of a laser light. This switching is b…

Approximately 65% of PSI structures report some type of ligand(s) that is bound in the crystal structure. Here, a description is given of how such ligands are handled and analyzed at the JCSG and a survey of the types, variety and frequency of ligands that are observed in the PSI structures is also compiled and analyz…

Spotless catalysts: Ligand immobilization was studied by two-photon fluorescence microscopy with a fluorescent nixantphos ligand as probe (see picture). In the immobilization process ligand aggregates form in solution and are deposited on the support, where they appear as bright spots in fluorescence images. Preventin…

Synchrotron X-ray diffraction and neutron diffraction have been used to investigate the phase changes that the titanosilicate mineral sitinakite undergoes when dehydrated. Refinements of the powder diffraction data of the material before and after heating to 573K indicate a phase change from space group P 4 2 / mcm to…

In this paper, we present a detailed study of localized two-photon photoluminescence from metal nanoparticles on a dielectric surface. An ultrafast (∼13 fs) near-infrared laser focused on a micrometer sized region is used to excite a silver nanoparticle covered quartz or mica substrate, and a pulse shaper is used to c…

Borate: guilty and charged! The borate ion, and possibly carbonate, enhances rates of steady oxygen-isotope exchanges at some, but not all, structural sites in polyoxometalate ions. Addition of an oxygen atom to an incoming neutral boric acid molecule (blue=boron) from a bridging oxygen atom on a decametalate ion is s…

A surface-modifier-assisted photodeposition technique for directly depositing PbS quantum dots on mesoporous TiO2 nanocrystalline films is developed (see figure). The addition of mercaptoacetic acid (MAA) drastically increases the photodeposition rate and significantly blueshifts the absorption edge. The PbS particle…
