We study photo-induced static and dynamic spectral changes in self-assembled CdSe/ZnS quantum dot (QD) thin films with varying QD concentrations under ambient conditions. Using spatially resolved scanning photoluminescence microscopy in conjunction with spectrally resolved time-correlated photon counting, we measure t…
Sodium lanthanide sulfate NaLn(SO 4 ) 2 ·H 2 O (Ln = Y, La to Yb) nano/microcrystals with multiform morphologies were successfully synthesized by a facile and effective hydrothermal method. The photoluminescence properties of the Ce 3+ and Tb 3+ single-doped as well as the Ce 3+ –Tb 3+ codoped NaY(SO 4 ) 2 ·H 2 O micr…
A general dynamic hysteresis core loss model has been developed. Experimental data for different lamination thicknesses have been measured and analyzed at various frequencies. Based on the analysis, a dynamic hysteresis finite element core loss model is established and validated by experiments. The developed dynamic h…
Reflected Mueller matrix spectra were measured and simulated for asymmetrical photoresist master diffraction gratings in conical mounting (i.e., the direction of grating grooves was not perpendicular to the plane of light incidence). From the electromagnetic reciprocity theorem, Mueller matrix of symmetric grating (co…
The main problem of renewable energy sources is their intermittency. Integration of energy storage devices with renewable energy systems can offer solution to this problem simply by storing excess produced energy for utilization when needed later on. Energy storage devices are also essential for other applications suc…
Multiscale molecular modeling (M 3 ) is applied in many fields of material science, but it is particularly important in the polymer science, due to the wide range of phenomena occurring at different scales which influence the ultimate properties of the materials. In this context, M 3 plays a crucial role in the design…
The modification of ferroelectric vortex domain patterns in hexagonal manganites (here exemplified by YMnO3 and HoMnO3) owing to chemical treatment, thermal annealing, and local electric-field poling is investigated by piezoresponse force microscopy. Chemical treatment transfers the domain pattern into a topographical…
The oxidation kinetics of SiC fiber-reinforced SiC matrix composites with a BN interphase (SiC/BN/SiC) and the constituent fibers was characterized by thermogravimetric analysis and microstructural characterization at temperatures (816-1538°C) and oxygen partial pressures (0.1% to 5% O 2 ) relevant to the hypersonic f…
Films from three different bloom strength were prepared and dried at three different temperatures (20 °C, 40 °C and 60 °C) to investigate whether the differences in ordering and aggregation during film formation, under controlled drying conditions, reflect changes in their mechanical properties. Results showed that Yo…
Phase-pure epitaxial thin films of (Ti,V)2GeC have been grown onto Al2O3(0001) substrates via magnetron sputtering. The c lattice parameter is determined to be 12.59 Å, corresponding to a 50/50 Ti/V solid solution according to Vegard’s law, and the overall (Ti,V):Ge:C composition is 2:1:1 as determined by elastic reco…
This paper presents investigations into the eddy current losses of laminated stator cores with electrically connected edge areas. The application of various manufacturing processes can lead to an electrical connection of the lamination core edges and therefore to additional eddy current losses. This paper considers th…
The synthesis and characterization of a novel fixative, guar gum-graft-poly(acrylamide-co-diallyldimethylammonium chloride) (GG-g-p(AM-co-DADMAC)) polymer is described. The grafted polymerproved to be effective at adsorbing hydrophobic wood resin particles onto papermaking fibre surfaces, thus removing wood resins fro…
Abstract An unusual occurrence of palygorskite was found near Montestrutto, lower Val d'Aosta (Italy), within an eclogite-facies leucogneiss of the Sesia-Lanzo zone. Under the optical microscope the mineral appears as a felt of fibres hundreds of μm long and a few μm thick. SEM observation proved each filament to be a…
Retanning process is one step of wet-finishing operations and is very important operation which overcomes the disadvantages of chrome tan. For this purpose two different nano-emulsions of styrene/acrylate copolymers have been prepared to be used as retanning agents. The main difference and characters of the two nano -…
The quality of finite elements simulations is depending on the used magnetic characteristic curves and material coefficients on a high degree. Especially in the automotive industry the power density of electric machines are tending to increase. Thereby the quality of a whole design optimization process for highly satu…
The present article investigates the recycling effect on properties of dilute suspension of HDPE reinforced by SGF without coupling agents. This dilute suspension at different proportions of SGF loading was produced by melt compounding cycles with a single screw extruder. The differential scanning calorimetry results…
Electrospinning from a single jet is commonly used to produce very fine polymeric fibers. The mass production rate of the electrospinning from a single jet is relatively low. Alternative methods to launch multiple jets and increase production rates are described here. Few variations on the electrospinning process are…
Many of the recent developments in nanoscience research using polyoxometalates (POMs) are reviewed. POMs consist of several octahedral made of transition metals (Tm) and oxygen, attached to one another by sharing oxygen atoms. This review demonstrates the important and variety role of POMs in the advances of nanotechn…
High-power piezoelectric characteristics under continuous driving were studied on some bismuth layer-structured ferroelectric ceramics, i.e., Sr 0.25 Bi 2.75 Ti 0.75 Ta 1.25 O 9 (SBTT, m = 2), Bi 4 Ti 2.98 V 0.02 O 12 (BITV, m = 3), Bi 4 Ti 3 O 12 –SrBi 4 Ti 4 O 15 + MnCO 3 0.2 wt % (BIT–SBTi, m = 3, 4), and (Sr 0.7 C…
