A series of Fe 1− x Mn x Se polycrystalline samples with , 0.02, 0.05 and 0.08 is prepared by conventional solid-state reaction. Normal-state transport of electrical resistivity and thermopower are investigated up to 700 K. The electrical resistivity monotonically increases with increasing Mn content. The temperature…
Delayed hot water in domestic water heating systems is a worldwide problem. In New Zealand, it accounts to over a 15 million cubic meters of treated water wasted per year. There are few commercial solutions proposed to minimize the problem, but none of them are affordable or practically convenient. To increase the tem…
BACKGROUND: One area of nanoscience deals with nanoscopic interactions between nanostructured materials and biological systems. To elucidate the effects of the substrate surface morphology and viscoelasticity on cell proliferation, fractal analysis was performed on endothelial cells cultured on nanocomposite samples b…
One of challenge for cancer therapy is efficient delivery of anticancer agents into tumor sites to increase efficiency of drugs and reduce side effects. To overcome this challenge, we designed pH- sensitive doxorubicin prodrug (DEX-PEI-DOX) nanoparticles based on dextran-poly(ethylene imine) copolymers (DEX-PEI). The…
Abstract Hloušekite, (Ni,Co)Cu4(AsO4)2(AsO3OH)2(H2O)9, is a new supergene arsenate mineral from the Geister vein (Rovnost mine), Jáchymov (St Joachimsthal), Western Bohemia, Czech Republic. It was found along with veselovský ite, pradetite, lavendulan, arsenolite, babánekite and gypsum on the surface of strongly alter…
Nanocomposites may be produced simply by combining two materials in such a manner as to produce domains of nanometric scale in the resulting composite [1]. True nanocomposites are distinct from simple mixtures in that they exhibit material properties that do not vary monotonically in proportion to the ratio of the con…
Objective(s): The silver nanoparticles, being very small size, can permeate the cellular membrane and interfere in the cell’s natural process. In the present study, the effects of time, the dosage of these particles and their use on blood molecules and hormones, the volume of drinking water, and the urine parameters w…
Capacitors made of metalized polypropylene film are components with high quality and stability. Electrical ageing of these capacitors causes changes in quality of thin film metal electrodes dominantly; changes caused in quality of PP film are low. Method of measurement of current-voltage characteristic nonlinearity wa…
It is established that Cu-1.6 at % Fe alloy tapes obtained through cold rolling to 98.9% followed by recrystallization annealing possess a sharp cube texture, which opens prospects of using thin tapes of this alloy as substrates for second-generation high-temperature superconductors. The optimum regime of annealing is…
Most of the works devoted to the study of measuring current and voltage transformers are focused on defining the characteristics of transformers in steady-state conditions to determine whether the transformers satisfy the metrological requirements. Such studies are often carried out using a chain of equivalent circuit…
The quality of three-layer pipes has been studied; they are manufactured by hot pressing of a three-layer assembly of tubular billets followed by forging and cold rolling. The operating core is made from a V-4Ti-4Cr alloy. The protective claddings are made from corrosion-resistant steels of two grades, 08Kh17T and 20K…
The aim of this paper is to describe the effect of training methods on the accuracy of PCA-KNN partial discharge (PD) classification model. This model used principal component analysis (PCA) combined with k-nearest neighbor (KNN) model, so called, PCA-KNN PD classification model for PD pattern classification. PD pheno…
PEG (polyethylene glycol) have been widely used in the synthesis of nanomaterials due to its special structure and performance. In this paper, the role PEG played in the preparation of nanomaterials, such as dispersion and stabilization, structure-directing, modification and functionalization were summarized.
We report the synthesis of monodisperse calcium carbonate (CaCO3) (nano)particles having either a cubic or spherical structure by reacting calcium nitrate with either sodium carbonate or citric acid, respectively, in the presence of cetyltrimethylammonium bromide (CTAB) via the sonication method. For comparison, CaCO3…
The quest for power electronic converters to operate in a subsea pressurized environment that is completely filled with appropriate dielectric liquid brings about the need to study the insulation performance of liquid in the system while in operation. One of the critical regions for electrical insulation is the trench…
The data presented in this work aim to provide a comprehensive characterization of lipid-coated gold nanoparticles. We show that it is possible to envelop gold nanoparticles with a coating of lipids during the formation of the gold nanoparticles, that the gold in these lipid-coated gold nanoparticles is crystalline an…
Carbon coatings were deposited on Nextel™440 fibres using C 3 H 6 –Ar system by hot wall chemical vapour deposition (CVD) with a total pressure of 1·5 kPa. The morphology and structure of the coatings were characterised by SEM, XRD and Raman spectroscopy. As the deposition temperature increased from 1173 to 1373 K, th…
With gold nanoparticles (AuNPs) is possible to develop nanoscale devices that can interact with chemical and biological systems. The phenomenon explored in these nanosystems is called Localized Surface Plasmon Resonance (LSPR), which promotes electromagnetic wave oscillation electronics on these small metallic structu…
A fabrication strategy is proposed to enable precise coverage of as-grown carbon nanotube (CNT) mats atop vertically aligned silicon nanowire (VA-SiNW) bundles in order to realize a uniform bundle array of CNT-SiNW heterojunctions over a large sample area. No obvious electrical degradation of as-fabricated SiNWs is ob…
A series of linear low-density polyethylene (LLDPE) nanocomposites containing different types of nanofiller (TiO2, MWCNT, expanded graphite, and boehmite) were prepared by in situ polymerization using a tandem catalyst system composed of {TpMs}NiCl (1) and Cp2ZrCl2 (2), and analyzed by differential scanning calorimetr…
