The PcBN materials were sintered from the cBN-Al systems under high-pressure and high-temperature, and the mechanical properties, composition and microstructure of prepared samples were analyzed. The results show that the microstructure is fairly even and the binding phase is uniformly distributed in its volume. The s…
In this paper we study certain subclasses of analytic p-valent meromorphic convex functions with positive coefficients in the puncture unit disk. The result presented coefficient estimate, growth and distortion properties for functions belonging to this subclasses. Further results of modified hadamard product, inclusi…

Both liquid chemical permeation rate of n-hexane and water vapour transmission rate (WVTR) of temperature sensitive polymer membranes made from N-isopropylacrylamide (NIPAAM) grafted Poly(vinylidene fluoride) (PVDF) copolymer (PVDF-g-NIPAAM) were studied in order to evaluate its potential utility as a smart barrier la…
Transformer winding deformation is common in transformer faults. Offline monitoring is mostly used in diagnosis of winding deformation, which has some limitations. So an online detecting method based on extraction of current is proposed. The method increases the higher harmonic of the current that flows into the input…
In the era of technological advances in various fields of development was rapid, it would require some sort of infrastructure for the era of free competition. One of the prospects for future development is to build a factory that has competitiveness with foreign products. One of them is by establishing Bisphenol-A pla…
This thesis describes the synthesis and structural characterisation of cyclometalated heteroleptic bis(tridentate)ruthenium(II) complexes based on [Ru(terpyridine)(1,3-dipyridylbenzene)]PF6, a cyclometalated analogue of [Ru(terpyridine)2](PF6)2. These complexes are investigated photophysically, photochemically and ele…
The purpose of this study is to investigate the elastic-plastic behavior of inclusions, i.e. SiO2 particles, in cold drawn wire using reverse analysis and nanoindentation test. First, the nanoindentation tests were performed to obtain indentation load P – penetration depth h curves. Second, the reverse analysis which…
Crystalline AlPO-11 and its metal substituted CoAlPO-11 was prepared by the hydrothermal method and characterized by X-ray diffraction, scanning electron microscopy, Fourier transform infrared (FT-IR) spectroscopy and ICP-AAS. All the samples crystallized with the AFI structure. The catalytic properties of the catalys…
Paper bricks – moulds of brick made of recycled paper as a primary composition – have already been tested and used (although limited) as good sources of domestic fuel, and this alone saves up on the excessive use of wood for fires. The main purpose of this project is to test and expand the uses of paper bricks, to are…
A number of different experiments on a dielectric elastomer, VHB 4910, were performed: uniaxial tensile strain tests, in situ SAXS/WAXS measurements of a sample under uniaxial tensile loading and DIC measurements of an electrically loaded circular sample with simultaneous force measurements around the circular boundar…
In this work, we have studied the optical properties of a crosslinkable poly amic acid containing Disperse Red 1. The thin films were cured at 130, 160 and 195°C. The structural and optical properties of the doped films were investigated by using UV-VIS spectra, and Prism Coupling techniques. The composite crosslinks…
马海毛作为最贵羊毛中的一种，其性能与外观都具有较高的品质，了解并熟悉马海毛的特性是熟练运用马海毛的一个重要前提。在马海毛材质针织服装的设计中，了解马海毛的特性并发挥其优势，熟悉马海毛与其它纱线之间的整合关系是将马海毛运用在针织服装肌理表达中的核心。 Mohair is one of the most expensive wools, whose performance and appearance are of high quality. Understanding and being familiar with the characteristics of mohair are an important premise to u…
以氧化石墨烯、明胶为原料，经冷冻干燥及高温碳化之后，得到了从明胶中得到的掺杂氮的碳片层包裹氧化石墨烯的新型催化剂。利用扫描电镜(SEM)、透射电镜(TEM)、X-射线衍射仪(XRD)和旋转环盘电极(RRDE)表征了化合物的物理特性和氧气还原反应的催化性能。在氧气饱和的0.10 mol/L KOH电解液中，该化合物对氧还原反应(ORR)表现出明显的电催化性能，起始电压为−0.11 V (vs. NHE)，在燃料电池和金属空气电池领域有潜在应用前景。 The nitrogen doped graphene/carbon based oxygen reduction catalyst has been synthesized by fr…
The production technology of casting of the main detail of the hinge of a cherpakovy chain from steel 40GT with a variable chemical composition on pine forest from an external surface of the plug to the internal is developed. Heat treatment increased hardness superficial the borirovannykh of layers of metal to 540 – 5…
Acquisition Software - C-Therm - Thermal Conductivity Instruments - Simplifying thermal conductivity and thermal effusivity analysis with the patented Modified Transient Plane Source technique.
It has been more than 50 years since the enzyme system ribonucleotide reductase (RNR), catalysing the reduction of ribonucleotides to deoxyribonucleotides, was first discovered. RNR was also the first time that radical chemistry was revealed in an enzyme. RNRs carry out a key step in the de novo synthesis of building…
The physical mechanical properties of Al-7000 aluminium foam product and processing has been evaluated in this study. The characterization through the compressive testing refers to flatwise direction provided more confident result than edgewise direction. This experiment may correlate with formation of side products o…
The isolation of crystallite anatase from commercial TiO2 P25 Degussa was investigated. The aim of this research was to study of isolated anatase based DSSC as an effort to develop industrial DSSC. The crystal phase, crystallite size and crystal shape both of original P25 and isolated anatase were characterized by XRD…
Diketopyrrolopyrole-naphthalene polymer (PDPP-TNT), a donor-acceptor co-polymer, has shown versatile behavior demonstrating high performances in organic field-effect transistors (OFETs) and organic photovoltaic (OPV) devices.
