In this work time resolved luminescence measurements on the red phase of 3BCMU are presented. These polydiacetylenes form an ordered and isolated one dimensional model system. This work is divided in two parts. First we present an excitation spectrum in ch ...
The process parameters of an inductively coupled thermal plasma used for nanopowder synthesis are experimentally investigated using various plasma diagnostics and in situ powder monitoring methods. An enthalpy probe technique is applied to characterize the ...
Photo-induced excited-state reactions stand in the center of function of the photosensitive biological systems. These reactions can be accompanied by structural changes of the chromophore (for example isomerization) which are influenced by the nearest envi ...
Proton magnetic resonance spectroscopy (1H-MRS) has been used in a number of studies to noninvasively assess the temporal changes of lactate in the activated human brain. However, the results have not been consistent. The aim of the present study was to te ...
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 ...
Experimental uncertainties concerning the coordination mode of trivalent plutonium in concentrated LiCl have led us to theoretically evaluate the f-f transitions of a series of rare earth aquo and chloro complexes. The calculation of Pr(III), U(III), Np(II ...
We report on the results obtained during the commissioning phase of the volume photoemission (VOLPE) project, now operational at ESRF. Test experiments were performed on noble metals and highly correlated systems, analyzing photoelectrons with kinetic ener ...
We report on a first-principles investigation of the structural and vibrational properties of vitreous germania (v-GeO2). Our work focuses on a periodic model structure of 168 atoms, but three smaller models are also studied for comparison. We first carry ...
To better understand the complex photophysics of the amino acid tryptophan, which is widely used as a probe of protein structure and dynamics, we have measured electronic spectra of protonated, gas-phase tryptophan solvated with a controlled number of wate ...
Since the first inductively coupled plasma (ICP) torch was developed in the 60's, RF thermal plasmas have found a variety of applications in material processing such as crystal growth, thermal spray coatings, spheroidization and vaporization of refractory ...
