Yb3+/Ho3+ doped hexagonal NaGdF4 nanocrystals are synthesized through solvothermal method, for which pure hexagonal phased nanorods are presented. The concentration influence of Yb3+ ions on the sample morphology and fluorescence emission of Ho3+ is investigated. It is found that the sample size is changed from 25 nm…
One of the best methods of detecting certain problems which can lead to failure of the transformer is Dissolved Gas Analysis (DGA). For diagnosing fault condition on oil filled insulation, one of the most recent techniques developed is Dissolved Gas Analysis. The chemical analysis of the generated gases is known as Di…
Collapse of building due to gas explosion or due to bombing has been occurred in past. Due to explosion a local load carrying member fails and the load carried by failed member get transferred as extra loads to adjacent members which are generally not designed for that, due to extra loads adjacent members gets failed…
Automobile companies are showing interest in reducing the weight of vehicle by replacing the steel by GFRC for increasing the fuel economy and performance. The Natural Fiber composites are the excellent alternative for the GFRC due to lightweight compared to steel and low cost as well as good elastic strain energy sto…
Because of the diversity in the morphology of carbon nanomaterials that can extend the practical application areas by using the morphologycorrelated properties thus, many researchers have found that there are diverse unique forms of the carbon nanomaterials, such as carbon nanotubes, graphenes, carbon coils, and so on…
The main goal of this book is therefore to provide the reader with an overview of various concepts in cluster physics and related topics in physics, and is based on lecture courses given by the author to undergraduate and graduate students at Kyoto University (Japan), to nuclear engineering students at Purdue Universi…
Solution combustion method was successfully used for the synthesis of nanocrystalline Mn1-xZnxFe2O4 with stoichiometry (x = 0, 0.1, 0.3, 0.5, 0.7, 0.9 and 1.0). The room temperature dielectric studies real and imaginary part of permittivity (epsilon' and epsilon `') were undertaken in the vide frequency range 1 MHz to…
CdS thin films of varying thickness were deposited on the glass substrate by chemical bath deposition (CBD) using Cadmium Chloride (CdCl2) and Thiourea ((NH2)2CS) as Cd and S sources respectively with ammonia as a complexing agent. The synthesized CdS thin films have been characterized using X-ray diffractometer (XRD)…
Transformers are an extremely important element of electrical power system. Detecting minor turn-to-turn faults on the power transformer winding is a difficult problem. Understanding frequency responses in relation to winding structures was developed by using experimental and simulation efforts. In this paper, n-secti…
Adv. Electron. Mater, 2016, 2, 1500467 An error is present in Figure 2 of this manuscript. The corrected version is below. The authors apologize for any inconvenience caused by this oversight.
In the paper was compared the stress state in front of the crack for SEN(B) specimens of S235RJ steel without and with delamination cracks. Stress distribution and characteristics of stress state triaxiality were calculated for both type of specimens. It was showed a reduction in the stress fields and triaxiality para…
A series of bifunctional Ni–S2O8 2−/ZrO2 (Ni x -SSZ-T) catalysts with different Ni mass fraction (x, %) and calcintion temperature (T, °C) were prepared by impregnation method. The catalysts were characterized by XRD, FTIR, and py-FTIR. The effects of Ni content and calcination temperature on the acidic property and i…
The phase composition of alloys in the Ag–Bi–S–I system (in the region AgI–Bi–Bi2S3–BiSI) for Т ≤ 550 K was studied by physicochemical analysis methods. Equations of overall potential-forming reactions involving the BiSI and Bi 19 S 27 I 3 phases were composed. The reactions were performed in the C|Ag|glass Ag 3 GeS 3…
Nanofibrillated cellulose (NFC) was prepared from cotton linter after electron beam irradiation to investigate its effects on the manufacturing efficiency of the NFC preparation and the property changes by the treatment. Mechanical device (Super Masscolloider) was used to prepare the NFC and its passing frequency for…
The oxidative conversion of ethane over a multicomponent oxide catalyst with the composition V 0.3 Mo 1 Te 0.23 Nb 0.12 was studied in the temperature range of 360–450°C. It was found that temperature did not affect the contribution from the parallel and consecutive paths of reaction product formation. The obtained da…
A series of single-frame and single-stringer compression tests were conducted at NASA Langley Research Center on specimens harvested from a large panel built using the Pultruded Rod Stitched Efficient Unitized Structure (PRSEUS) concept. Different frame and stringer designs were used in fabrication of the PRSEUS panel…
The work presents non-local line method by which the equivalent fatigue zones were designated. These zones are one-dimensional efficient lengths in which operating stress variables cause initiation of fatigue cracks. The algorithm of the presented method considers the issues of multi-axial stress state, critical plane…
The study presents the numerical simulation of the void nucleation process due to decohesion of the interface between the matrix and inclusion of iron carbide Fe3C, under high stress state triaxiality ratio, which is equal to 1.345. The analysis was conducted for S355J2G3 steel, commonly used in civil engineering stru…
세계적으로 사용 중인 대부분의 추진물질들은 연소 시 메탄가스, 이산화탄소 등의 환경유해 물질을 다량 발생시킨다. 본 연구에서는 이러한 문제를 개선하기 위해 에너지 가소제로 사용 가능한 고질소 화합물인 트리아졸 계열의 4,5-bis(azidomethyl)-methyl-1,2,3-triazole(DAMTR)의 합성공정을 확립하였다. 또한, 분광분석(NMR, IR)을 통해 DAMTR의 구조를 분석하였고, 유리전이온도, 녹는점, 분해온도, 밀도, 점도, 충격감도, 점도, 휘발성 등의 물리적 특성을 측정하였다. 그리고 Gaussian 09와 EXPLO5를 이용하여 생성열과…
