Here we report a one-pot route for the synthesis of nickel dodecahedra with 52.3 ± 0.1 emu g(-1) of saturation magnetization. The procedure is very simple, and only three chemicals (NiCl2·6H2O, isopropanol and polyvinylpyrrolidone) are used throughout the entire synthetic process. During the reaction, it is believed t…
Dear Gun, and Master Sommelier Blind-Tastes a Glass of Water David Hernandez (bio) Dear Gun Again you’re on television,printed repeatedly in newsprint,on pages of overcast sky that crackle when turned.On monitors too,glowing bluely across America. On our minds and tongues,your word, monosyllabic, justthree curled fing…
Scratch tests on (001) face, doubler face and tripler face of KDP crystals are carried out at room temperature. It shows that the friction ceoffcients of different crystal faces are affected seriously by the crystal oritations, their variation periods of (001) face, doubler face and tripler face are 90o, 180o and 180o…
We report the mass production of Ni metal nanoparticles using dc transferred arc thermal plasma reactor by homogeneous gas phase condensation process. To increase the evaporation rate and purity of Ni nanoparticles small amount of hydrogen added along with argon in the plasma. Crystal structure analysis was done by us…
Liquid crystal (LC) lenses have been the subject of research due to their advantage of focal length tunability that brings added value to applications typically based on conventional gradient index lenses. A novel approach for modeling the unwrapped phase defects in modal LC microlenses is presented. For solving the g…
The present study deals with the application of non-destructive radio isotopic tracer technique to evaluate the performance of nuclear grade resins Tulsion A-30 and Dowex 550A LC. The evaluation was made by testing the performance of the two resins during iodide and bromide ion-isotopic exchange reactions. It was obse…

The present trend in power electronics is the increase of power density and the reduction of the size and cost of devices. It is now mandatory to find new solutions to reach high integration levels without decreasing the efficiency and by considering thermal issues. Recently, a new family of low-loss ferrites emerged…
The principal possibility to use byproducts of acidic processing of aluminium-bearing raw materials as the main component of batch to obtain a heat insulating material using low-temperature technology is established. The compositions suitable to obtain low-temperature frit and a foam glass material on its basis are de…
In this work, we theoretically and numerically demonstrate several new plasma filament-based structures used for increasing the angular and range resolution of microwave radar systems, and show that they can survive in adverse environments.
Abstract Presently, double melted, cold worked and stress relieved Zr-2.5%Nb alloy pressure tubes are employed in some of Indian Pressurized Heavy Water Reactors (IPHWRs) where initial hydrogen content is limited to 25 wppm . Over a period of time, part of hydrogen/deuterium released by the corrosion reaction (metal-c…
Photovoltaic effect on single-crystalline silicon treated by compression plasma flows is studied. A number of samples (1 1 cm) of single-crystalline silicon with n- and p-types of conductivity and different dopant concentrations (p-type silicon doped by B: 0.3, 4.5, 10, 12 Ω cm; n-type silicon doped by P: 0.5, 4.5, 20…
KNO3 nano-particles with the diameter of about 28 nm were prepared by mechanical milling using planetary ball mill from the commercial KNO3 powder. Rotation speeds of ball mill were 0 to 500 rpm, where the milling time was kept at 15 minutes. Magnetization was measured by SQUID magnetometer. The milled sample at 500 r…

Recently the first porous hydride, gamma-Mg(BH4)2, featuring so-called "borohydride framework" and capable to store reversibly guest species was discovered [1]. This example clearly shows that the covalently bound hydride anions, such as borohydride, can act as directional ligands, capable to form molecular and polynu…
Charge transport in conjugated polymers as well as in bulk-heterojunction (BHJ) solar cells made of blends between conjugated polymers, as electron-donors (D), and fullerenes, as electron-acceptors (A), has been investigated. It is shown how charge carrier mobility of a series of anthracene-containing poly(p-phenylene…

Solid polarisable activated carbon electrodes have been prepared from Coconut shells and Rice husks. The preparation process involved precursor pre-carbonizations and conversion to solid carbon discs, inert environment carbonization and C02 activation at 7500C. Electrochemical Impedance spectroscopy characterizations…
In this paper, the HAZ of pipeline steel in high heat input welding is researched, including the microstructure and properties of HAZ, the embrittlement of HAZ and the existing problems and solutions of HAZ. The results show that the welding normalized zone is the best part of the HAZ. The main embrittlement mode of H…
