Improving CASINO performance for models with large number of electrons
Quantum Monte Carlo calculations have at their core algorithms based on statistical ensembles of multidimensional random walkers which are straightforward to use on parallel computers. Nevertheless some computations have reached the limit of the memory resources for models with more than 1000 electrons because of the…

Low-variance Monte Carlo Solutions of the Boltzmann Transport Equation
We present and discuss a variance-reduced stochastic particle method for simulating the relaxation-time model of the Boltzmann transport equation. The present paper focuses on the dilute gas case, although the method is expected to directly extend to all fields (carriers) for which the relaxation-time approximation is…

FTIR Analysis of $Bi_2O_3-B_2O_3-Fe_2O_3$ Glass System Doped with $Nd_2O_3$
In the present work $Bi_2O_3-B_2O_3-Fe_2O_3$ glasses have been prepared via melt quenching method. The composition has been fixed to 60 mol% B2O3, 20 mol% $Bi_2O_3$ and 20 mol % $Fe_2O_3$ which is a stable glass forming composition. In these glasses, $Nd_2O_3$ has been doped in exchange of $Fe_2O_3$ concentration. FTI…
Wavefunctions and carrier-carrier interactions in InAs quantum dots studied by capacitance-voltage spectroscopy
Das Ziel der hier vorgelegten Arbeit ist es, Modifikationen des Ladungsträgereinschlusses an InAs-Quantenpunkte zu\nuntersuchen. Insbesondere die resultierende Veränderung der Löcherwellenfunktion und die Coulomb-Wechselwirkungen im\nLeitungsband Grundzustand sind Bestandteil dieser Arbeit. Um dieses Ziel zu erreichen…
Ferromagnetic Resonance Investigations on Styrene-Butadiene-Styrene Barium Ferrite Nanocomposites
FMR measurements on barium ferrite nanoparticles (with an average length of about 13 nm) dispersed within a block copolymer (styrene-butadiene-styrene) are reported. Resonance spectra have been successfully simulated by a convolution of a Dysonian line and a Lorentzian line. The temperature dependence of FMR spectra i…
Surface Analysis in Nanotechnology
The physical and instrumental background of commercially available surface analytical techniques based on electron spectroscopy and mass spectrometry are briefly described. Their application to the characterization of nanoscopic structures and material properties is elucidated by a number of practical and technologica…
Diffusion of cyclic versus linear poly(oxyethylene) oligomers in poly(methyl methacrylate) by ATR-FTIR spectroscopy
Diffusion of linear and cyclic poly(oxyethylene) (POE) oligomers in poly(methyl methacrylate) (PMMA) matrix was investigated in situ using attenuated total reflectance (ATR) infrared (IR) spectroscopy technique. The temperatures of studies were 60 oC, 85 oC and 110 oC. A film of PMMA was solution-cast onto an ATR zinc…
trans-Bis(5-carboxy-2-methyl-1H-imidazole-4-carboxylato-κ2N3,O4)copper(II)
In the title compound, [Cu(C(6)H(5)N(2)O(4))(2)], the copper(II) atom lies on an inversion centre and is in an N(2)O(2) four-coordinate environment with a nearly regular square-planar geometry. An extended network of intra-molecular O-H⋯O and inter-molecular N-H⋯O and C-H⋯O hydrogen bonds stabil-izes the crystal struc…
