A ZnO modified TiO2 (ZnO/TiO2) film was prepared by immersing TiO2 electrodes in Zn(Ac)2 aqueous solution. The open circuit voltage of a dye sensitised solar cell (DSSC) with the ZnO/TiO2 film electrode has a dramatic enhancement, compared to the DSSC with the TiO2 film electrode. However, the short circuit current de…
An analytical study of artificial materials created by embedding spherical nano-particles in an infinite homogenous medium is presented in this paper. Propositions by various contributors to this area of the nanomaterials' field have been compared with respect to their approaches in finding the effective constituent p…
Based on the characteristics of SBS modified asphalt (SBSMA) and crumb rubber modified asphalt (CRMA), crumb rubber and SBS composites modified asphalt (CR/SBSCMA) technology is proposed combine the advantages of crumb rubber and SBS. The preparation technology and production process factors have been discussed in thi…
The authors investigate the light-trapping efficiency of nanoimprinted ceramic grating reflectors for crystal silicon photovoltaic cells. Using 25 μm silicon wafers as a model system and hemispherical reflection measurements, they demonstrate a 4%–6% increase in AM 1.5 solar-photon absorption for one-dimensional squar…
To understand the effects of thermal gradient field with phase change on the crystal morphologies of high density polyethylene (HDPE) during gas assisted injection moulding (GAIM) process, the combination of the simulation of the temperature field via an enthalpy transformation method and the hierarchical structures a…
The effects of Zn2+ substitution on the sintering behavior and dielectric properties of Nd1−xZnxNbO4−x/2 ceramics were investigated. The synthetic process and phase evolution were studied using TG-DSC and X-ray diffraction (XRD) analysis. The results show that Zn2+ substitution lowers the densification temperature of…
Hexagonal base pyramid microwave absorber is the new design of microwave absorber. In this work, two sub-shapes are considered to compare it reflection loss performance. The shapes are hexagonal and truncated hexagonal base pyramid. Three sample of agricultural waste are used that is rice husk, rice straw and banana l…
The article discusses the process of electrodeposition of lead-tin alloy (tin content in the deposit up to 10–12 wt %) from methanesulfonate electrolytes. A composition was proposed of organic additives to the electrolyte providing attainment of high quality microcrystalline coatings with the alloy of predetermined co…
Europium-doped zirconium oxide (ZrO2:Eu3+) nanofibers were prepared via electrospinning, in which a mixture of zirconium chloride oxide octahydrate, europium nitrate hexahydrate, poly(vinyl pyrrolidone), dimethylformamide, and ethanol were electrospun at atmospheric conditions. Subsequent calcination to produce ZrO2:E…
The CNRS has been involved in molten salt reactors since 1997. Starting from the Molten Salt Breeder Reactor project of Oak-Ridge, an innovative concept called Molten Salt Fast Reactor or MSFR has been proposed, resulting from extensive parametric studies in which various core arrangements, reprocessing performances a…
In this paper, analysis impulse voltage distribution in transformer winding, and winding of the voltage impulse response with a standard full wave and clipped wave especially at the ends of the entanglement presented. Compared with experimental data EMTPDC simulation, the result of t; 2.0 μs was obtained near the same…
We report on a contactless, all-optical method to derive thermal properties of 340 nm thin, 640×640 μm(2) wide, freestanding silicon membranes. Exploiting the temperature dependent optical transmissivity of 4×10(-3)/K between 300 and 470 K, we are able to measure the temperature of the membrane with millikelvin therma…
Skin analysis is one of the most important procedures before medical cosmetology. Most conventional skin analysis systems are semi-automatic. They often require human intervention. In this study, an automatic facial skin defect detection approach is proposed. The system first detects human face in the facial image. Ba…
The critical current of an internal tin Nb3Sn wire developed by Oxford Instruments, Superconducting Technology for International Thermonuclear Experimental Reactor (ITER) (OST type-I, billet No. 7567) has been studied under axial strain at fields between 12 and 19 T at 4.2 K. Simulating the situation in a cable in con…
The photoinduced stiffening (PIS) and photoplastic effect (PPE) of ZnS individual nanobelt (NB) were observed by using a nanoindenter in conjunction with an incident ultraviolet (UV) light source system. The results show that the elastic modulus and hardness of ZnS individual NB under UV illumination are at least 32%…
AIM: Macrophages play a key role in the initiation, progression and complications of atherosclerosis. In this article we describe the synthesis of biocompatible, paramagnetic, fluorescent phosphatidylserine vesicles containing cholesterol ester with a free carboxylic acid function and its use for targeted imaging of m…
Defect-modified copolymer P (VDF-CTFE) has a high dipole density and breakdown field, and BaTiO3 (BT) has a high dielectric constants. Both their characteristics can be achieved in P(VDF-CTFE)/BT composites. The powders of BaTiO3 was manufactured by sol-gel methods and coupled in KH550. The composites which is compoun…
Poly(3-hexylthiophene) (P3HT)-C60 organic photovoltaic devices with interpenetrating donor-acceptor interfaces were fabricated by oblique thermal deposition of C60 into the P3HT nanogratings. The uniformity and step coverage of C60 infiltration into the P3HT nanostructures, which can determine the device performance,…
Abstract One widely accepted approach – component additivity (CA) – to describe the sorption of contaminants onto complex materials such as rocks or soils is based on the assumption that the surface of a complex mineral assemblage is composed of a mixture of mineral constituents whose surface properties are known from…
Phenylene-based polymers are a widely studied class of blue-emitting materials for use in polymer light-emitting diodes intended for display applications. This review looks at the various types of such polymers that have been synthesised and the problems that have arisen in obtaining stable and efficient blue emission…
