Abstract Hardwood spent mushroom substrate was employed as a carbon precursor to prepare activated biochars using phosphoric acid (H 3 PO 4 ) chemical activator. The activation process carried out an impregnation ratio of 1 precursor:2 H ; pyrolysis temperatures 700, 800, and 900 °C; heating rate 10 °C min −1 treatment time h. specific surface area (SSA) the reached 975, 1031, 1215 m 2 g for sa...

Nanobiotechnology appears to be an emerging science which leads to new developments in the field of medicine. Importance of the magnetic nanomaterials in biomedical science cannot be overlooked. The most commonly used chemical methods to synthesize drugable magnetic nanobeads are co-precipitation, thermal decomposition and microemulsion. However monodispersion, selection of an appropriate coati...

Inorganic thiosulfate has been implicated as an intermediate in the assimilation of sulfate in a variety of organisms. Nutritional studies with mutants of Aspergillus have been interpreted to indicate thiosulfate as an intermediate between sulfite and cysteine (1, 2), possibly via a pathway involving cysteine-Ssulfonate as a direct precursor of cyst&e (24). Shepherd earlier had envisioned the u...

A facile method was successfully developed to prepare strontium-tantalum perovskite oxynitride, SrTaO2N, and its solid solutions. Urea employed as a nitriding agent eliminate the use of toxic NH3 gas. In addition, utilization sol-gel-derived Ta2O5 gel Ta precursor allowed for completion nitridation within shorter period at lower calcination temperature compared with conventional ammonolysis pro...

Abstract Synthesis of silver nanoparticles using a bioreductant simpur leaf extract to minimize the use inorganic materials that are harmful and not environmentally friendly. Silver with bioreduction method, solution was mixed AgNO3 precursor addition PVA concentrations 0%, 0.75%, 1.5% 3%. The purpose this study determine effect on characteristics antibacterial activity. Analysis functional gro...

Organic-inorganic hybrid materials can be prepared dispersing organic species into well-defined inorganic nanoblocks. This paper describes the immobilization of natural dyes from the extract of the Brazilian açaí-fruit into two types of layered hexaniobate precursors derived from H(2)K(2)Nb(6)O(17): (i) colloidal dispersion of niobate exfoliated nanoparticles and (ii) niobate pre-intercalated w...

In the present study, twenty-five male goat kids (20±2.5 kg BW) were used during an 84- day experimental period to determine the effect of source and level of sulfur supplementation on mohair characteristics and performance. Experimental diets were diets containing 0.18% (as control), 0.24% and 0.34% DM inorganic or organic sulfur. The data were analyzed as a 2 × 2 factorial design. Methionine ...

Surface concentrations of secondary inorganic particle components over the UK have been analysed for 2001–2010 using the EMEP4UK regional atmospheric chemistry transport model and evaluated against measurements. Gas/particle partitioning in the EMEP4UK model simulations used a bulk approach, which may lead to uncertainties in simulated secondary inorganic aerosol. However, model simulations wer...

Co-self-assembly of mesostructured silica films from solutions of tetrahydrofuran (THF) and water, silica precursor species, and structure-directing Pluronic P123 block-copolymer molecules is reported with and without conjugated polymer guest species. The solution-phase behavior of the ternary THF-water-P123 system guided the selection of nonequilibrium synthesis conditions that allowed highly ...
