Die typischen hohen C- und Si-Gehalte von Gusseisenwerkstoffen und der weiche Graphit limitieren die Behandel- und Beanspruchbarkeit nach dem Nitrieren und der Hartstoffbeschichtung. Wenn die Gusseisenoberfläche vor den genannten Randschichtbehandlungen mittels Elektronstrahls umgeschmolzen wird (Kombinationsbehandlun…
Front Cover: An atmospheric pressure diffuse dielectric barrier discharge between cylindrical rotary electrodes was applied for deposition of silica-like moisture barrier films on polymer foil. The discharge was operated in N2/O2/Ar gas mixture with the addition of tetraethyl orthosilicate. It is shown that high quali…
Effect of Ag addition on the age-hardening response and precipitate microstructure of the Al-3.0Mg-1.0Cu (wt%) alloy has been investigated by micro Vickers hardness and transmission electron microscopy (TEM). The alloy compositions located in the (+S+T) phase field of the Al-Mg-Cu phase diagram are known to be effecti…
Equipping one support structure with DC and AC systems in parallel can increase the transport capacity of existing transmission corridors. The constant electric field of the DC system induces a constant DC component into the AC systems in near vicinity. All magnetic equipment including an iron core is in danger to sat…
Wear and tear, electrification and aging of (low voltage) distribution grids require maintenance in order to assure continuous provision of electricity. Situational awareness is required to find out when parts of the grid need maintenance and which parts should be prioritized. The paper proposes a conceptual value mod…
This paper presents a novel synchronous reference frame based (SRF) control strategy for shunt hybrid active power filter (SHAPF). The control strategy includes a direct current control (DCC) and an indirect current control (ICC) strategy. SHAPF can achieve harmonic compensation and dynamic reactive power compensation…
This manuscript describes an electrospinning method for fabrication of highly aligned poly(vinylidene fluoride-trifluoroethylene) copolymer (P(VDF-TrFE)) nanofibers. In our experiments, micro-patterned parallel electrodes are used to modify the electric field nearby the collector, and electrospun nanofibers achieve go…
A controllable and area selective doping process, especially for p-type Molybdenum disulphide (MoS2), is essential for the realization of various p/n junction-based devices. In this work, we demonstrate p-type doping of multilayer MoS2with phosphorus (P) as a dopant using a CMOS-compatible plasma immersion ion implant…
Abstract New Pb2PdO2(OH)2 and Pb2PdO(OH)4(H2O) were synthesized at ambient conditions from respective KOH alkaline and metal nitrate aqueous feed stocks in high purity and as coarse crystals. The constitutions of the two lead palladates were determined by combined powder neutron and single‐crystal X‐ray diffraction st…
We demonstrate piezoresistive strain sensors based on flexible MoS2field-effect transistors made from a highly uniform large-area trilayer film. The origin of the piezoresistive effect in MoS2is explained to be a strain-induced band gap change, as confirmed by optical spectroscopy. The results are in good agreement wi…
This study introduces indirect water cooling systems and their improvements utilized in proto typing of vehicle machines. Due the vehicle machines require high torque at acceleration they are often equipped with indirect liquid cooling. One common method to implement liquid cooling is a water jacket inside machine fra…
The vortex lattice (VL) in the mixed state of the stannide superconductor Yb3Rh4Sn13 has been studied using small-angle neutron scattering (SANS). The field dependences of the normalized longitudinal and transverse correlation lengths of the VL, ξ(L)/a0 and ξ(T)/a0, reveal two distinct anomalies that are associated wi…
We develop a computational method for optical response of a supported cluster on a dielectric substrate. The substrate is approximated by a dielectric continuum with a frequency-dependent dielectric function. The computational approach is based on our recently developed first-principles simulation method for photoindu…
Properties of chromogenics materials have been of great interest for more than 50 years till now. Some examples of their practical application are photochromic lenses, electrochromic smart windows or even some examples of sensors devices based on gasochromic thin lms have already been commercially available on the mar…
Results of numerical simulations of channeling of ultra-relativistic positrons are reported for straight and uniformly bent diamond crystals. The projectile trajectories in a crystal are computed using a newly developed module of the MBN Explorer package which simulates classical trajectories in a crystalline medium b…
The acoustic characteristics of the 1515 aluminum sub-microcrystalline alloy that were obtained by equal channel angular pressing (ECAP) are investigated. It was found that the action of short-term (5, 10, and 15 min) low-temperature (T = 0.4 T melt) annealing substantially increased both the attenuation coefficient a…
A new 2-tosylaminobenzylidene-2′-amino-5′-chlorothiophenol ligand and its mono- and binuclear copper complexes are synthesized. Their structures are characterized by IR, 1 H NMR, and magnetochemistry. In the copper binuclear complex there is the antiferromagnetic exchange interaction between paramagnetic centers. The…
The phase composition and spectral-luminescent characteristics of yttrium partially stabilized zirconia (YSZ) crystals doped with Nd 2 O 3 and CeO 2 (ZrO 2 -Y 2 O 3 -Nd 2 O 3 -CeO 2 ) are studied. X-ray diffraction shows that YSZ ZrO 2 -2.5 mol %Y 2 O 3 -0.2 mol %CeO 2 -0.1 mol %Nd 2 O 3 , ZrO 2 -2.03 mol %Y 2 O 3 -0.…
We explore the effective potential landscapes that extended particles experience when adsorbed on the surface of quasicrystals. Commonly, these are solids with long-ranged order but no translational symmetry. The effective potentials significantly depend on the size of the adsorbed particles. We show how changing the…
This work deals with the vibrational, thermal and dielectric characterization of a synthetic peptide (S4) released during the proteolysis of human tropoelastin. This peptide was shown to form amyloid-like fibers implied in neurodegenerative pathologies. The comparison between the linear peptides and the associated amy…
