When metal complexes and clusters are bonded to oxide or zeolite supports, they may combine the technological advantages of solid catalysts (robustness for high-temperature operation, lack of corrosiveness, ease of separation from products) with the selectivity of soluble molecular catalysts. Supported mononuclear met…

This study attempts to develop Ti-Nb alloys with elastic moduli that approach that of human bone. The experimental results reveal that the microstructure of a Ti-Nb alloy that contains 14 mass% Nb consists of α and β phases, with α phase being the dominant one. The proportion of the α phase decreases gradually as the…

Using X-ray induced photoelectron spectroscopy, the influence of Brønsted acids, namely sulfuric, nitric, and hydrochloric acid on the electronic properties of single-walled carbon nanotubes (SWCNTs) was investigated. Doping effects were monitored by changes in binding energy of the C 1s core level of the nanotubes. F…

Heat conduction of finite-length single-walled carbon nanotubes (SWNTs) was simulated by the molecular dynamics method with Tersoff-Brenner bond order potential. Temperature at each end of an SWNT was controlled by the phantom technique, and the thermal conductivity was calculated with Fourier’s law from the measured…

A new strategy to build caged-compounds is presented. The approach is based on heterolytic photocleavage of a metal-ligand bond in a coordination compound. A ruthenium polypyridine complex, containing the neurocompound 4-amino pyridine (4AP) is used as the core of the phototrigger. The biomolecule is released by irrad…

Many organisms from a wide variety of taxa produce amorphous calcium carbonate (ACC), despite the fact that it is inherently unstable and relatively soluble in its pure state. These properties also make it difficult to detect and characterize ACC. Raman spectroscopy is a particularly useful method for investigating AC…

Abstract Divalent and multivalent metallic compounds catalyze the flame retardancy performance of intumescent systems based on ammonium polyphosphate (APP) and pentaerythritol (petol) in poly(propylene) (PP). The catalytic effect is shown by increases in the oxygen index (OI) and UL‐94 ratings. The effect is exerted b…

The synthesis of water-soluble Mn doped ZnS nanocrystals with MPA (3-mercaptopropionic acid) as stabilizer is described. The coordination of Zn ion with MPA helps efficient doping of Mn and thus makes the process reproducible as compared to the common co-precipitation method. To obtain a high luminescent intensity, po…
