Inspired by the efficiency of the photo-Fenton process on oxidation of organic pollutants, we herein present the feasibility of visible light driven photo-Fenton process as a post treatment of biological method for the effective degradation and detoxification of monoazo dye Mordant Yellow 10 (MY...

Carmoisine is an azo dye widely used in many industries, and therefore frequently occurs in the effluent of many factories. To our knowledge, biological degradation of carmoisine has received little attention. The present study investigates the capability of Saccharomyces cerevisiae ATCC 9763 fo...

The commercially available Fe0 aggregate has advantages of low-cost, fast-effective decontamination, reusability, and ease of operation. However, little study has been done on the performance of Fe0 aggregate as a catalyst in degradation of azo dyes, particularly used in persulfate (PS) oxidatio...

This paper presents some modifications of the melanin formation assay for tyrosinase from the point of view of both eu- and phaeomelanosynthesis. On the one hand, eumelanosynthesis can be estimated using neutral paper filters, such as the 3MM Whatman filters so far employed. The main advantages ...

The skin pigment melanin is produced in melanocytes in highly specialized organelles known as melanosomes. Melanosomes are related to the organelles of the endosomal/lysosomal pathway and can have a low internal pH. In the present study we have shown that melanin synthesis in human pigment cell ...

Tyrosinase expression was examined in hair follicles from twenty three red- and dark-haired individuals. Tyrosinase activity was greater in the hair follicles of red-haired subjects than in those from dark-haired subjects. Tyrosinase synthesis was also greater in the red-haired subjects and this...

Melanin synthesis in the mouse involves the interaction of many pigmentation loci. Tyrosinase, the product of the albino (c) locus, catalyses the first step of the pathway. The brown (b) locus protein has significant homology to tyrosinase and controls black/brown coat coloration, but its functi...

Sexually selected traits confer greater reproductive benefits to individuals with more elaborate forms of the signal. However, whether these signals convey reliable information about the physiology underlying trait development remains unknown in many species. The steroid hormone corticosterone (...

A simple procedure was developed to synthesize molybdenum carbide nanoparticles (Mo2C/BC) by carburization of molybdate salts supported on the biochar from pyrolysis of biomass without using extra carbon source or reducing gas. The molybdenum carbide formation procedure investigated by in-situ X...

Al2O3-, SiO2-, and SiC-supported molybdenum carbide catalysts promoted by nickel for the dry reforming of methane were evaluated at 800 °C. Several oxide precursors were synthesized and carburized using temperature-programmed carburization (TPC). The precursors and catalysts were characterized ...

Depolymerization of lignin into aromatic compounds in high yield for production of fuels and chemicals is vital to realize an economically competitive biorefinery. In this study, undoped and nickel-doped bulk molybdenum carbides were synthesized and evaluated in reductive depolymerization of lig...

Searching for high-efficiency and earth-abundant electrocatalysts towards hydrogen evolution reaction (HER) is one of the most promising pathways to ameliorate environmental contamination. In this work, we report a facile protocol to achieve the synthesis of the coupled molybdenum carbide and mo...

Clay sample of Qulapalk – Sulaimani of Kurdistan region of Iraq was analyzed for its chemical composition and mineralogy. Calcite (a non-clay mineral) was a major constituent of the sample (34%). The main clay mineral was smectite as depicted by X-ray diffraction patterns of the oriented slides...

Conventional antimony metallurgy had the problems of low-concentration SO2 pollution and high energy consumption. This work proposed a new clean metallurgy method for antimony extraction. Zinc oxide and carbon were used as sulfur-fixing and reducing agent, and metallic antimony was obtained one ...

Gliosis including microgliosis and astrogliosis is a response to central nervous system inflammation. The purpose of this study was to evaluate whether olfactory bulbs are influenced by intranasal exposure to the detergent Triton X-100, a non-ionic surfactant. In this experiment, we measured olf...

Penitrem A is a fungal neurotoxin that recurrently causes intoxication in animals, and occasionally also in humans. We have previously reported that penitrem A induced the production of reactive oxygen species (ROS) in rat cerebellar granule cells, opening for a new mechanism of action for the n...

Developing high-capacity electrode materials is critical to enhance the energy-density of lithium-ion batteries. Here, a new graphene nanoplatelets-supported SiOx-disordered carbon composite (SiOx-C/GNPs) is fabricated by a Stöber-type process and high-temperature treatment. When used as an anod...

The design and fabrication of two-dimension (2D) nanostructure carbon with desired lithium-ion storage properties is highly demanded for substitution graphite. Herein, the hierarchically porous carbon nanosheets with hybrid N, P functionalization (NPHC) via a layered magadiite surface-induced st...

The impact of calcium and gypsum on separation of scheelite from fluorite using sodium silicate as depressant was investigated by micro-flotation tests, X-ray photoelectron spectroscopy (XPS), zeta potential measurements and solution chemical analysis. The flotation results confirmed that sodium...

First results of the cooling rate dependent vitrification process of a silicate melt in the cooling rate range between 0.1 and 30,000 K/s are presented. These results are compared with the temperature dependence of the shear viscosity. The results indicate that rule of the proportionality betwee...
