Recovery of sparse signals from linear, dimensionality reducing measurements broadly fall under two well-known formulations, named the synthesis and the analysis a ́ la Elad et al. Recently, Chandrasekaran et al. introduced a new algorithmic sparse recover ...
A non-thermal plasma rector with a catalytic electrode made of sintered metal fibres (SMFs) was tested for the oxidative decomposition of a model VOC toluene. The input energy was varied in the range 160-295 J/I by varying the applied voltage between 12.5 ...
Clusters in the (Be, B, C)@Si-n((0,1,2+)) (n = 6-10) series, isoelectronic to Si-n(2-), present multiple symmetric structures, including rings, cages and open structures, which the doping atom stabilizes using contrasting bonding mechanisms. The most strik ...
The interactions between 60 degrees dislocation pile-ups with grain boundaries (GBs) are studied using multiscale modeling. Careful quantitative analyses of complex processes associated with 60 degrees dislocation absorption and transmission phenomena at S ...
Since more than twenty years it is known that deposition of Ag onto Si(111)–(7×7) leads under certain conditions to the formation of so-called “ring-like” clusters, that are particularly stable among small clusters. In order to resolve their still unknown ...
The timescales for structural changes in a single crystal of bismuth after excitation with an intense near-infrared laser pulse are studied with femtosecond pump-probe X-ray diffraction. Changes in the intensity and reciprocal-lattice vector of several ref ...
A direct multiscale method coupling molecular dynamics to finite element simulations is introduced to study the contact area evolution of rough surfaces under normal loading. First, a description of the difficulties due to using the bridging domain method ...
We applied density functional theory based on ultrasoft pseudopotentials to study the structural properties of Ir-4 clusters both in the gas phase and adsorbed on a MgO(100) surface. To resolve the discrepancy between experimental data which suggest a tetr ...
Due to their limited length of structural coherence nanocryst. materials show very diffuse powder x-ray diffraction patterns that are difficult to interpret unambiguously. A combination of high-energy x-ray powder diffraction and at. pair distribution func ...
The solid solubility of germanium in silver has been measured in the temperature range of 520 K to 913 K via measurements of density and of electrical conductivity of two near-eutectic Ag-Ge alloys. The atomic fraction of germanium in solid solution varied ...
