The 8–18 GHz microwave transmittance, absorption, permittivity and microwave conductivity have been investigated for nanocrystalline Ni0.4CoxCd0.6−xFe2O4 (x = 0.0, 0.2, 0.4, 0.6) prepared by auto combustion method. The X ray diffraction pattern reveals the nanocrystalline cubic spinel structure with crystallite size 1…
Few data exist on the change of mobility of ions in nonpolar dielectric liquids by pre-irradiation of the liquid sample with ionizing radiation. Such data are especially important for cases where such liquids are used in devices, which operate under exposure of high-energy radiation. Examples are transformers in nucle…
An angular dependence of domain wall (DW) motion is studied in a magnetic wire consisting of a giant-magnetoresistance spin-valve. A DW pinning site is formed by a single notch, where a conventional linear one and a specially designed tilted one are compared. The asymmetric angular dependence was found in the DW depin…

The results of mathematical modeling of heating mains laid out without canals, as well as numerical analysis of their heat losses in the presence of ground freezing in the area of installation are presented. The laws of heat transfer in the system and the factors influencing the intensification of heat losses are esta…
Recent decades witnessed an explosion of new materials and new ways to fabricate/use naturally occurring and engineered materials. Scientists and engineers from various fields refer to this development to understand fundamental materials structure and accordingly material properties and function. Therefore, it is cruc…
Abstract Ruthenium tris-bipyridine derived complexes functionalized by either carboxyl or phosphonyl groups were tested as sensitizers for the photocatalytic reduction of carbon dioxide in the presence of nickel cyclam acting as a catalyst, and a sacrificial donor. These systems were shown to be as efficient as the un…
Divalent europium-activated strontium silicate (Sr2SiO4:Eu2+) phosphors were prepared at relatively low temperature via a conventional solid-state reaction method, in which BaF2 was used as both flux and component. The effect of BaF2 on XRD patterns and luminescent properties of Sr2SiO4:Eu2+ was investigated. BaF2 cou…
In previous work, we have reported that a P3HT:PCBM-based organic photovoltaic cell using a thermally evaporated DMDCNQI buffer layer shows a high power conversion efficiency. In the present work, we have fabricated organic photovoltaic cells consisting of ITO/PEDOT:PSS/P3HT:PCBM:DMDCNQI/DMDCNQI/Al using an all-soluti…
Nanocrystalline 4Fe-Al2O3 composite was simultaneously synthesized and consolidated by pulsed current activated sintering (PCAS) method within 5 min from mechanically activated powders of Fe2O3 and 2FeAl. The average grain size and mechanical properties of the composite were investigated. The average grain sizes of Fe…

Visualization of biomolecules in living bodies has attracted increasing attention in recent years. Magnetic resonance imaging (MRI) is a noninvasive technique that yields high-resolution structural information of deep anatomical regions; therefore, it has promising applications in the development of probes to visualiz…
The phase gratings have been recorded in silver halide emulsion (Slavich PFG-01) by utilizing a two-beam laser interferometric technique and Kodak DA-163 as a developer. Such gratings are observed to conform to both the surface relief and refractive index modulations. In the present work, we have studied the contribut…

폴리우레탄 접착제의 내가수 분해성 향상을 위하여 실란 커플링제를 첨가하여 특성을 고찰 하였다. 실란 커플링제는 사슬 내에 2종 이상의 다른 기능성기를 가지고 있는 3-isocyanatopropyl triethoxy silane (ITS)을 사용하였는데 일반적으로 고분자와 무기, 유기 또는 금속소재와의 복합계에서 계면결합으로 접착성 개선을 가져올 수 있다. 본 연구에서는 폴리우레탄 접착제 제조에서 ITS의 양을 0, 0.3, 0.5, 0.7 및 1 wt%로 첨가하여 샘플을 제조하고 가사시간, modulus, 내열성 및 접착력을 평가하였다. ITS가 첨가된 샘플은 대부…
College profs spend a great amount of time reading and commenting on students' written work. This can be a real struggle! The precision and clarity required in science writing are often alien to first-time lab students who have been tutored by high school English teachers to include elaborate metaphors and colorful vo…
Self-assembled GaSb nano structures were grown on GaN/sapphire. GaSb nano triangles as well as quantum dots were obtained under controlled growth conditions. Nano triangles were grown at 580 degrees C due to the growth rate anisotropy among the (1100) planes. The size of nano triangle was 87 nm in width, 5 nm in heigh…

Vertically aligned carbon nanofibers (VA-CNFs)-carbon nanowalls (CNWs) have been prepared on a silicon (Si) substrate by plasma-enhanced chemical vapor deposition. The VA-CNFs-CNWs were formed at bias voltage of - 185 V, whereas conventional VA-CNFs were synthesized under conditions of high bias voltages. Degenerated…
