In this study, to understand the effects of paramagnetic impurities, we investigated the temperature dependent of the spin-lattice relaxation times of pure LiNbO3, LiNbO3:Mg, LiNbO3:Mg/Ti, LiNbO3:Mg/Fe, and LiNbO3:Mg/Fe (thermally treated at 500°C) single crystals. The results for the LiNbO3:Mg single crystals doped w…
MnAlFe alloy was prepared by the combined use of smelting, high-energy ball milling and tempering heat treatment process. The phase composition and microwave absorbing properties of MnAlFe alloy were investigated by X-ray diffractometer(XRD) and vector network analyzer. The results show that the powders consist of Al8…

In this paper we study the morphology of drops formed on partially wetting substrates, whose footprint is not circular. These drops are consequence of the breakup processes occurring in thin films when anisotropic contact line motions take place. The anisotropy is basically due to the hysteresis of the contact angle s…
Mass transfer was examined at a stationary rectangular copper electrode (cathode) by using the reduction of cupric ions as the electrochemical reaction. The influence of electrolyte temperature (25, 45, and 65 oC), and cupric ions concentration (4, 8, and 12 mM) on mass transfer coefficient were investigated by using…
Nowadays, constant pressure on enviromental aspects in the foundry industry is calling for an improvement in casting production. The almost not used inorganic binders are coming back to the fore. Into this group, among others, belong binders based on alcali silicate solutions, known as water glass. The new hot-curing…
In this work, anthocyanin dye was extracted in ethanol from black rice and used as a sensitizer together with CdS and CdSe quantum dots (QDs) in a QD-dye-co-sensitized TiO 2 solar cell. QDs were prepared via wet solution processed method. Performances of the natural dye-sensitized solar cells with iodide based or coba…
We introduce a novel apparatus designed for stress-controlled rheometers to perform simultaneous rheological and electrical measurements on strongly conductive complex fluids under shear. By means of a non-toxic liquid metal at room temperature, the electrical connection to the rotating shaft is completed with minimal…
ABSTRAK Kerajinan kerang simping atau dalam bahasa latinnya Amusium pleuronectes banyak diminati oleh konsumen. Umumnya produknya berupa kap lampu yang dibuat dengan sistem bingkai menggunakan kuningan. Pada beberapa daerah kuningan sulit diperoleh, sehingga perlu dilakukan penelitian produk kerang dengan sistem bingk…
Dy1-x(Gd or Yb)xBa2Cu3O7-δsamples were prepared using chemical solution deposition, based on trifluoroacetate metal-organic decomposition methods. X-ray diffraction results demonstrated the formation of the RE123 superconducting phase with strong in-plane and out-of-plane texture. For all samples doped with Gd or Yb,…
Composite fibrous electrospun membranes based on poly(dl-lactide) (PLA) and poly(e-caprolactone) (PCL) were engineered to include borate bioactive glass (BBG) for the potential purposes of guided bone regeneration (GBR). The fibers were characterized using scanning and transmission electron microscopies, which respect…
Favimat single fibre tester is non-conventional textile testing equipment. Review of several Textile Testing textbooks revealed that neither any information nor mentioning of the equipment was provided even in the most recent publications. As a result, the mainstream force of textile professionals in most countries, i…
In this work we report the preparation of rigid microcellular polyurethane/carbon nanotube nanocomposites with different CNT loadings (0.09-0.46%) and various isocyanate indexes (110-260). Water was used as a blowing agent for samples. Density of all obtained samples – 200 ± 10 kg/m 3 . Electrical properties, as well…
In this paper, the properties of carbon fibers before and after their gaseous oxidation are evaluated using the RAMAN spectroscopy and electron paramagnetic resonance.
Fuel cells are one of the cleanest and efficient technologies for electricity generation with products of water and heat. Polymer Electrode Membrane (PEM) fuel cells has been widely recognized as the most promising technique for future generating devices in the automotive, distributed power generation and portable ele…
In this paper we demonstrate a solution to achieve robust enhancement-mode Al2O3/GaN MISFETs with a high breakdown voltage and suggest a possible model for the device off-state breakdown. It is found that the device breakdown exhibits different gate voltage dependence for different surface treatments before the gate d…
Three-dimensional (3D) porous Au nanocoral network (GNN) structure was fabricated on glassy carbon (GC) electrode by one-step, template-free electrodeposition and decorated with ultrathin Pt film by combining the underpotential deposition (UPD) of copper adatoms and the galvanic displacement (GD) between PtCl 6 2- and…
The results of studying the self-locking of dislocations, namely, the transformation of glissile dislocations into blocked dislocations in the absence of an applied stress, are generalized. The existence of selflocking is theoretically grounded and experimentally proved via the observation of dislocation extension alo…
This paper considers ways to improve the electric strength of a high-voltage bushing by decreasing the maximum electric intensity. For a coaxial cylindrical bushing with radii r 0 and r m > r 0, which result in an insulation gap (r m –r 0) with permittivity ε0, this problem is solved with the use of an additional laye…
Ge and B diffusion was studied in nanocrystalline Si, and Pd and Si self-diffusion was studied in nanocrystalline Pd2Si during and after Pd/Si reactive diffusion. These experiments showed that grain boundary (GB) diffusion kinetic is the same in micro-and nanoGBs, whereas triple junction (TJ) diffusion is several orde…
