Femto- to picosecond excited-state dynamics of the complexes Re(L)(CO)(3)(N,N) (N,N = bpy, phen, 4,7-dimethyl-phen (dmp); L = Cl, n = 0; L = imidazole, n = 1+) were investigated using fluorescence up-conversion, transient absorption in the 650-285 nm ...
Carbon dioxide and the carbonates, the available natural C-1 sources, can be easily hydrogenated into formic acid and formates in water; the rate of this reduction strongly depends on the pH of the solution. This reaction is catalysed by ruthenium(II) pre- ...
Copper and silver cation-exchanged zeolite SSZ-13 present an interesting opportunity to study the mechanism of interaction of adsorbate gases, primarily hydrogen (H2), with the ion-exchange sites in zeolites as there is only one type of cation site, in con ...
A homogenous catalytic system has been developed that efficiently and selectively decomposes formic acid into hydrogen and carbon dioxide. [Ru(H2O)6]2+, [Ru(H2O)6]3+ and RuCl3·xH2O are all excellent precatalysts in presence of TPPTS (TPPTS=meta-trisulfonat ...
A clear description of the paths of thermal decomposition of complex borohydrides represents a crucial step forward to their utilisation as a reservoir of hydrogen and hence as materials for solid state hydrogen storage. We present in this work a theoretic ...
We demonstrate a novel approach for high-throughput and high-resolution fabrication of engineered infrared plasmonic antenna arrays with reusable nanostencils for vibrational spectroscopy. Optical responses of these antennas are identical to ones fabricate ...
Using high-throughput instrumentation to screen conditions, the reaction between FeCl2 and H3BTT·2HCl (BTT3- = 1,3,5-benzenetristetrazolate) in a mixt. of DMF and DMSO gave Fe3[(Fe4Cl)3(BTT)8]2·22DMF·32DMSO·11H2O. This compd. adopts a porous three-dimensio ...
The introduction of hydrogen in transport, particularly using fuel cell vehicles, faces a number of technical and non-technical hurdles. However, their relative importance is unclear, as are the levels of concern accorded them within the expert community c ...
This study aims at an investigation of the impurity gases emitted during the decomposition of borohydrides. For this we have set up a quantitative gas analysis based on a combination of FTIR spectroscopy and gravimetry. We show that the emission of various ...
Temperature dependence of physical and mechanical properties is considered in most thermal and mechanical response models for composite materials. Based on thermogravimetry analysis, differential scanning calorimetry, and dynamic mechanical analysis conduc ...
