The V 3 O 7 /graphene oxide nanocomposites (V 3 O 7 /GO) were synthesised by a hydrothermal method. In the nanocomposites, the V 3 O 7 nanobelts are dozens of nanometres in width and several micrometres in length. Acted as the electrode materials, the V 3 O 7 /GO nanocomposites exhibit a high initial discharge capacit…
We propose a new electromagnetic shielding (EMS) sheet that uses carbon nanotube (CNT)-composite paper. The electromagnetic environment in which electronic devices such as mobile phones and personal computers operate has become increasingly complex due to increased electromagnetic noise. This noise can cause unexpecte…
The aim of this study was to determine the diagnostic accuracy of early/delayed (123)I-β-methyl-iodophenyl pentadecanoic acid ((123)I-BMIPP) planar images to detect disrupted fatty acid metabolism in patients with vasospastic angina (VSA). Heart-to-mediastinum (H/M) ratios and washout rates were calculated from early…
The surface plasmon polariton (SPP) modes of gold nanobars (nanowires with rectangular dimensions) have been investigated by scanning pump-probe microscopy. In these experiments the nanobars were suspended over trenches cut in glass coverslips, and propagating SPP modes were launched in the supported portion of the na…
To study crack initiation at weak stress singularities classical Fracture Mechanics approaches do not suffice. In this work weak singularities are discussed and the obstacles occurring in fracture analysis are outlined. The concept of Finite Fracture Mechanics and the use of coupled criteria is explained. A brief disc…
A novel method of copper indium diselenide nanoparticle (CuInSe 2 NP) synthesis using a two-step, continuous flow, solar microreactor is reported here.
Highly conjugated energetic salts exhibit remarkable thermostability and insensitivity.
Localized surface plasmon resonance (LSPR) sensor is constructed by immobilizing gold nanoparticles (AuNPs) on the surface of hetero-core structured fiber optic and characterized as a refractive index sensor. According to increasing of dipping time of the aminated sensing part in the AuNPs suspension, the propagating…
P3HT degrades homogeneously and the degradation rate is reduced by a factor of 3 in the presence of PCBM. Spatial photodegradation maps are obtained by scanning transmission X-ray microscopy near the carbon absorption edge.
The new compound HP-Na2Co[PO4]F was synthesized by high pressure solid state reaction and its crystal structure was determined from single crystal X-ray diffraction data. The physical properties of HP-Na2Co[PO4]F were characterized by magnetic susceptibility, specific heat capacity, galvanometric cycling, and electroc…
Hybrid materials formed from acid functionalized multi-walled carbon nanotubes (MWCNTs) and glutathione (GSH)-capped ZnSe quantum dots (ZnSe QDs) were prepared by a non-covalent self-assembly method. Black spots decorated on the surface of MWCNTs under transmission electron microscopy (TEM) demonstrate successful atta…
Electrochemical anodic oxidation of nickel superalloy ZhS32 under the action of a direct current in an acid solution H 2 SO 4 + HCl has been studied to reveal its efficiency for combined processing of the wastes of this alloy. The material balance of the process and the approaches to processing the formed materials fo…
This paper established 3D coupled thermo-mechanical finite element simulation model of a conical ring rolling process. Three simulation experiments were designed and performed. The effects of key simulation parameters such as mass scaling factor, time scaling factor and remeshing sweeps per increment on simulation tim…
The growing demand for chromium coated aluminium components especially for the automotive industry is due to their favourable physical properties (density, strength to weight ratio etc.). However, their frequent use under harsh environmental conditions renders them corrosion sensitive and consequently they need to be…
The study of silicon species in organic-rich waters is a very significant problem. This type of waters is widely spread all over the world. It is characterized by a high content of humic substances, high color of water and low pH. In this regard, a certain determination of silicon concentration in this type of waters…
In the absence of experimentally determined three dimensional (3D) structures of proteins, the prediction of protein structures using computational methods is a standard alternative approach in bioinformatics. When using the predicted protein models to compute the native structure of an unknown target protein, estimat…
Use of boron compounds has not become widespread because of the hardening and the other related problems in cementitious composites. The boron compounds as an additive material can be used widely in the production of cement and concrete in case of the elimination of these negative conditions. Thus the control of worka…
The electroless nickel-phosphorus based composite coatings are popular because of their outstanding hardness, yield strength, better resistance to wear, frictional resistance, corrosion resistance, and good lubricity. In the present study attempts is made to investigate the influence of process parameters on the surfa…
Blends obtained by mixing high temperature applications thermoplastics have been investigated. Namely the blends considered in this work are made by semi-crystalline thermoplastics PEEK with amorphous PEI. The final goal is to analyse the mechanical, chemical-physical and environmental resistance characteristics of th…
Pd-decorated amorphous Ni–B/C catalysts were successfully synthesized which exhibited enhanced oxygen reduction reaction activities in alkaline media.
