A durability study was performed on a pultruded glass fiber reinforced polymer (GFRP) compression element of a hybrid GFRP/steel joint for concrete structures. GFRP elements were immersed in alkaline pore water solutions of different temperatures during 18 ...
Quantum state-resolved sticking coefficients on Pt(111) and Ni(111) surfaces have been measured for CH4 excited to the first overtone of the antisymmetric C-H stretch (2ν3) at well defined kinetic energies in the range of 10-90 kJ/mol. The ground state rea ...
A new tandem reaction leads to bicyclic cyclohexene derivatives with complete control of the relative configuration of the four chiral centers formed. The high diastereoselectivity is the consequence of an endo-selective Diels-Alder reaction followed by an ...
The mechanism of the reaction between the complex [Re(OH)(CO)(3)(N2C2H4)] and azetidin-2-one or 3-formylamino-N-sulf onatoazetidin-2-one was investigated by using the B3LYP density functional theory methodology in conjunction with the PCM-UAHF model to tak ...
In this work, I present the results of my studies on the state-resolved reactivity of silane (SiH4) on the Si(100)-(2x1) surface. The results demonstrate a co-existence of both a direct and a precursor mediated mechanisms for the dissociative chemisorption ...
Investigations of spectrum adjustment by unfolding techniques for different locations of critical and driven subcritical MUSE4 configurations are presented. The current analysis is based on the recent accomplishment of specific foil activation measurements ...
We derived an orbital dependent Kohn-Sham based scheme for the correction of the self-interaction error in DFT, which is particularly suited for the study of open shell molecular systems. Our approach is based on a weighted form of the Perdew and Zunger (P ...
Aminosilane solutions with pH equal to 8 and to 11 were applied and cured on SiO2 coated poly(ethylene terephthalate) (PET) films. The permeability of the silane-silica hybrid coating on PET was reduced twofold compared to that of the SiO2/PET film, at sol ...
Effects of channel bowing on the pin power and 238U capture rate distributions have been studied experimentally and analytically in a test zone consisting of 9 full-size Westinghouse Atom SVEA-96+ fuel assemblies in the PRO-TEUS critical facility. A very s ...
A detailed characterization of the time scales and mechanisms by which RNA molecules change their folding structure upon binding of metabolites or during catalysis is important for the understanding of the different biological functions of RNA. The folding ...
