Region of East Prussia is investigated very low in Lithuania and in Poland. The aim of this investigation is to make complex analysis and to compare folk home textile of East Prussia weaved in territories of Lithuania and Poland presenting technological recommendations for reconstructions manufacturing. In this work t…
A new MnZn ferrite with low core loss, P cv and high saturation flux density, B s above 100C have been developed as a material suitable for transformer or inductor cores, which operate in the high temperature range from 130 to 150C. The material with the B s of 400mT at 140 C and the P cv of 286kW/m 3 at 140C, 100 kHz…
The combination of a glycine-derivative supramolecular salt with lanthanide( iii ) chloride hydrates under hydrothermal conditions (120 °C, 48 h) produced a family of isotypical materials formulated as [Ln(bodt)(Hbodt)].
In the present work, we report the preparation of a fluorescent carbon nanodots (C-dots) epoxy composite thin films on a glass substrate. C-dots were prepared directly by a simple hydrothermal method using citric acid as a carbon source. The C-dots solutions were mixed with a transparent epoxy resin to form C-dot epox…
We study the alignment of single‐wall carbon nanotubes (SWCNTs) in bubble imprints through polarized Raman microscopy. A hemispherical bubble containing SWCNTs is pressed against a glass substrate, resulting in an imprint of the bubble membrane with a coffee ring on the substrate. We find that macroscopic ensembles of…
Mn substituted Mg-Zn ferrites have been synthesized by employing a co-precipitation technique using oxalate precursors. Initial permeability is found to increases initially up to x = 0.10 and with further addition of Mn2+ content it decreases. The observed variation in initial permeability can be explained by consider…
The surface of Zn–Al-chloride LDH microcrystals (LDH = Layered Double Hydroxides) was activated by grafting a redox active catechol bearing bis-phosphonate obtained by dopamine derivatization.
The mode III fracture analysis of graded cracked plane in the framework of classical and strain gradient elasticity is presented in this work. Solutions to the problem of screw dislocation in plane are available for classical and strain gradient elasticity theories. Different approaches for the formulation of the stra…
We report the dependence of the characteristics of photovoltaic organic light-emitting diodes (PVOLEDs) on the composition of the light-emission and electron-donating layer (EL-EDL). 5,6,11,12-Tetraphenylnaphthacene (rubrene): dibenzo{[f,f′]-4,4′,7,7′-tetraphenyl}diindeno[1,2,3-cd:1′,2′,3′-lm]perylene (DBP) was used t…
In this paper, controlling chaos when chaotic ferroresonant oscillations occur in a voltage transformer with nonlinear core loss model is performed. The effect of a parallel metal oxide surge arrester on the ferroresonance oscillations of voltage transformers is studied. The metal oxide arrester (MOA) is found to be e…
TiO 2 replica of ZnO nanosheets were synthesized, showing exceptional e-transport properties in dye solar cells.
In polymers, the electronic activation energy depends on the fragmentation, crosslinking, dopants, moisture and in general on the structure-environment interaction. This has a special importance in plasma polymers because fragmentation and crosslinking are usually higher than in other polymers. In this work, DC electr…
Metal-free organic sensitizer consisting of donor, electron conducting, and anchoring anhydride groups was engineered at molecular level and synthesized. Dye sensitized solar cells based on conjugated naphthalene dye were fabricated using nanoporous electrode. Photoelectrodes with a 7 μm thick nanoporous layer and a 5…
Corrosion fatigue small crack growth rates have been determined for a 12Cr steam turbine steel in a simulated condensate solution under conditions representing repetitive turbine start-up and shut-down. Cracks were grown from a single corrosion pit generated electrochemically using the droplet technique and the crack…
Polymers with individually adjusted optical and rheological properties are gaining more and more importance in industrial applications like information technologies and for biological use. With respect to the aspired applications the refractive index n of a matrix polymer has to be adjusted. For a refractive index inc…
In order to improve the matrix microstructure of SiC-fiber-reinforced SiC matrix (SiC/SiC) composite, the authors examined a combination process involving the polymer impregnation and pyrolysis (PIP) process and a pore-producing treatment that incorporates a pore-forming agent into the matrix precursor. Unidirectional…
Abstract The present work consists in the development of an autonomous, low cost, reliable, energy scavenger sensor for automotive applications. Thermoelectric generators typically exhibit low efficiency but high reliability, making them suitable for autonomous, low average energy consumption, applications. A prototyp…
The Raman spectra of the mixtures containing the low-temperature ionic liquid ethylmethylimidazolinium bis(trifluoromethanesulfonyl)imide (EMIIm), the salt component lithium bis(trifluoromethylesulfonyl)-imide (LiIm), and the aprotic solvent ethylene carbonate (EC) are studied. It is found that the addition of the lit…
A novel coil based cylindrical architecture for TCO-less DSSC is reported. The steps of fabrication involved are relatively fast and easy for the mass production of DSSC. Advantages over the previous cylindrical architectures in many aspects are described. The effect of different metal wire characteristics on the sola…
Multi-gripper flexible stretch forming is a novel sheet metal forming process aimed at improving the conformability of sheet metal to forming die, material utilization and forming quality of sheet metal. Straight jaws in traditional stretch forming machines are replaced by a pair of opposed clamping mechanisms movable…
