Displacement of a labile ligand from appropriate precursor complexes by 2- or 4-PPh2C6H4COOH yields neutral gold(I) and gold(III) [AuXn(PPh2C6H4COOH)] (n = 1, X = Cl; n = 3, X = C6F5), cationic gold(I) [Au(PPh2C6H4COOH)2](CF3SO3), and neutral chromium(0) [Cr(CO)5(PPh2C6H4COOH)] metallo-organic acids. [AuCl(4-PPh2C6H4C…
Denim is the worldwide much popular form of fabric. A faded stylish look can be achieved due to ring dyeing of warp yarns of denim garments. This effect occurs naturally in the process of indigo dyeing. Stonewashed cotton fabrics with finest washed appearance are generally woven from ring spun yarns which are ring dye…
This objective of this article is to present a new technique of nanofluids/MQL in high speed milling by using MWCNTs. In the past, studies have shown the MQL process can improve tool life and surface accuracy in high speed cutting. The purpose of using carbon nanotubes is to increase the thermal conductivity of cuttin…
Monazite is a light rare earth phosphate which is difficult to process when using conventional chemical processes. It is considered to be one of the most important commercial sources of thorium and lanthanides. Using conventional chemicals to process monazite have caused severe environmental damage as has been demonst…
Summary In the search for new biodegradable materials is found the combination of natural fibers with conventional polymeric materials or biodegradable polymers. The incorporation of natural fibers to thermoplastic polymer matrix is associated with improvement of their properties due to advantages such as the fact tha…
Dielectric breakdown strength of poly (ethylene-co-butyl acrylate) (EBA) nanocomposites filled with spherical alumina particles was studied as a function of particle coating, moisture content and the effective specific surface area. Two kinds of alumina nanoparticles were used: NA (25 nm in diameter) or ND (45 nm in d…
According to DFT PBE/3 z calculations, conformational transformations of 1,1,1-trifluoroethane molecule in model single-walled carbon nanotubes are determined primarily by the diameter of the latter. Reduction of the nanotube diameter is accompanied by displacement of the conformational equilibrium toward the eclipsed…
The rate of leaching of actinide-simulating rare-earth elements from two types of crystalline matrices consisting of titanate and titanozirconate phases was examined. The experiments were carried out at 95°C in distilled water. The rates of REE leaching from the samples were below 10 −3 g/m 2 day, which satisfied the…
Abstract This article provides information on the metallurgy of austenitic stainless steels, and the formation of their intermediate phases (Sigma, Chi, and Laves). It discusses sensitization, a major problem associated with the austenitics, and solutions to avoid the problem. The article describes heat treatments app…
Single-crystal X‑ray diffraction of trona, Na 3 CO 3 HCO 3 ·2H 2 O, was measured between 100 and 340 K at ambient pressures, and the infrared and Raman spectra of this material characterized to ∼25 GPa. The thermal expansion of trona is greatest in the b direction, which is due to a particularly large expansion of the…
Yarn-like carbon nanotube (CNT) fibres are a hierarchically-structured material with a variety of promising applications such as high performance composites, sensors and actuators, smart textiles, and energy storage and transmission. However, in order to fully realize these possibilities, a more detailed understanding…
Iron losses are one major origin of losses in highly utilized electrical machines. This work presents how iron losses can be modeled including material deterioration due to manufacturing processes. The obtained model is used to improve the machine design process and understand currently used building factors. These fa…
Nanocadmium sulphide (CdS) has been prepared by the one‐pot solid‐state method from cadmium chloride (CdCl 2 ) and sodium sulphide (Na 2 S) without any capping agent. The grinding period plays a major role in transforming CdS from the cubic (zinc blende) to the hexagonal (wurtzite) phase, hitherto unreported at the lo…
Partial discharge (PD) analysis is an important tool for assessing the lifespan of power equipment especially in cables and high voltage (HV) transformers. Different PD sources have different effects on the condition and performance of power equipment insulation system. Therefore, the ability to identify different PD…
This work develops an amplitude method for the photothermal (PT) technique to analyze the amplitude of the thermal radiation signal from the surface of a multilayered film sample. The thermal conductivity of any individual layer in the sample can be thereby determined. Chemical vapor deposited SiC film samples (sample…
Valve hall fittings' corona characteristics, corona inception electric-field strength and the critical electric-field values are the key factors to consider while designing fittings. Furthermore, the characteristics and value have guiding significance for engineering application. However it is difficult to obtain elec…
We report first investigations on a ferroelectret transducer material that is based on the same layer sequence as a simple electret microphone. Only one electrically charged polymer film is employed instead of two as in previous tubular-channel ferroelectrets. The new materials design has major advantages such as a re…
Viruses are important for a range of modern day applications. However, their utility is limited by their susceptibility to temperature degradation. In this study, we report a simple system to compare the ability of different dried protein films to stabilize viruses against exposure to elevated temperatures. Films from…
Biosolids handling is an energy intensive and expensive process. Thus, the use of beneficial end-products is strongly desired to reduce costs. Pyrolysis, the thermal decomposition of organic matter under anaerobic conditions, has potential to be a beneficial biosolids handling process. Pyrolysis results in biochar tha…
Nanocarriers show incredible potential in theranostic applications as they offer diagnostic capabilities along with the ability to encapsulate and protect drugs from degradation, be functionalized with targeting moieties and be designed with controlled release mechanisms. Most clinically approved nanocarrier drugs are…
