A higher manganese silicide (HMS) thermoelectric, with composition MnSi1.74, densified by spark plasma sintering, was successfully coated with a glass-ceramic, in order to be used at temperatures higher than 500 °C. Compositional changes in both the HMS substrate and the glass-ceramic coating a...

Neanderthal material culture patterning in Western Europe has been primarily approached from retouched stone tools and associated flake production methods. While considerable effort has been devoted over the past decade to better characterize Middle Palaeolithic lithic techno-complexes (LTCs) in...

Barium and manganese-doped zinc silicates was prepared under hydrothermal treatment by mesoporous template route employing mesoporous silica as an active template. The sample displays a rod-like morphology with a mean diameter of ∼40 nm and a mean length of ∼450 nm, which inherits the characte...

Polymeric aluminum ferric silicate (PAFSi), which is a composite coagulant, was prepared for high-oil-containing wastewater treatment. X-ray diffraction, scanning electron microscopy, and infrared spectra were used to characterize the structure of the PAFSi coagulants. The characterization resul...

Brackish coal seam water produced from the coal seam gas (CSG) industry is often treated by reverse osmosis to make the water suitable for beneficial reuse. As such, pre-treatment technologies are required in order to minimise membrane fouling. It was our hypothesis that coagulants may be able t...

Poly-silicic-cation coagulants (PSiCs) were prepared from industrial wastes such as fly ash, pyrite slag and wasted sulfuric acid by synchronous-polymerization and co-polymerization, and were denoted as PSiCs and PSiCc respectively. Their structures and morphologies were characterized and compar...

By finding appropriate recycling approaches, the volume of wastes, corresponding disposal cost, and the pollution of environment could be diminished. Also, such promising approaches can result in the conservation of natural sources and economic benefits. Aluminum dross as a hazardous solid waste...

The coastal northern Gulf of Alaska receives significant fluvial inputs from the numerous glaciers and rivers that border the region. The distribution of dissolved (soluble and total) and particulate aluminum (leachable and total) was examined in coastal surface water transects and vertical prof...

Silicon (Si) is reported to improve salt stress tolerance of cereals, but little is known about the effects of Si on flows and partitioning of sodium (Na+), chloride (Cl−), and essential mineral ions at the tissue and cellular level. Wheat (Triticum aestivum L.) was exposed to 200 mM NaCl for 30...

Natural attenuation of polychlorinated biphenyls (PCBs) by indigenous bacteria is an effective remediation strategy for polluted marine sediments. This study investigated the relationships between PCB concentrations in sediment pore water, humin electron transfer capacity, and potential PCB dech...

The bio-based material polyamide 56 (PA 56) is a new kind of biopolymer. Reactive Blue P-3R, which is a derivative of anthraquinone, can react directly with the amino groups on PA 56. 3,3′,4,4′-Benzophenone tetracarboxylic acid (BPTCA), which is a photoactive derivative of benzophenone, can al...

This study focuses on the investigation of removal of textile dye (Reactive Yellow) by a combined approach of sorption integrated with biodegradation using low cost adsorbent fly ash immobilized with Pseudomonas sp. To ensure immobilization of bacterial species on treated fly ash, fly ash with i...

The aqueous degradation of Reactive Yellow 84 (RY84) by potassium peroxydisulfate (K2S2O8) has been studied in laboratory scale experiments. The effect of the initial concentrations of potassium peroxydisulfate and RY84, pH and temperature on RY84 degradation were also examined. Experimental dat...

Textile wastewater represents a serious environmental issue due to the presence of toxic dyes. The cloud point extraction, which involves the application of nonionic surfactants at temperatures above the cloud point, was applied in this research to remove Reactive Blue 19 dye from a synthetic wa...

SummaryIn dentistry, blue light is widely used for tooth bleaching and restoration procedures involving composite resin. In addition, many dentists use magnification loupes to enable them to provide more accurate dental treatment. Therefore, the use of light is indispensable in dental treatment....

Reactive Blue-19 (RB19) is an anthraquinone based vinylsulphone dye, which is very difficult to degrade by chemical oxidation because its anthraquinone structure is stabilized by resonance. It has 75–80% fixation efficiency on the cellulose (cotton textiles) and the unfixed dye persists in the ...

Effluents from textile industry are a major source of environmental pollution, especially water pollution. One of the commonly used nanoparticles is zinc oxide (ZnO). In this study, the toxicity of solutions containing the Reactive blue 29 dye after nano-catalytic process UV/ZnO using the model ...

Aromatic Tb(III) chelates can be detected down to subnanomolar concentrations at polystyrene-carbon black composite electrodes on the basis of hot electron-induced electrochemiluminescence, and used as electrochemiluminescent labels in bioaffinity assays. The excitation mechanism is based on che...

Nanoscale Fe-Ni bimetallic particles with Polyvinyl pyrrolidone (PVP) as a stabilizer were synthesized for dye decolourization and characterized by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM) and nano particle size analyser. Analysi...

Black silicon is a kind of micro-/nanostructure formed on the surface of silicon, which can greatly reduce light reflection. In this review, five main fabrication techniques of black silicon are introduced and these techniques can change the morphology of the surface of crystalline silicon to a ...
