Activated carbon (AC), a porous material with high pore volume, attracts increasing attention owing to its potential applications in several fields. The development of a porous structure in AC marginally relies on both the treatment methods and the type of precursor. Thus far, both renewable and nonrenewable precursor sources have been used to synthesize AC with high surface area and pore volume. This study presents the synthesis of AC via physicochemical treatment of waste oil fly ash (OFA), a waste material produced from power plants.

This study was aimed to investigate the potential of single culture of fungi Aspergillus niger, to decolorize reactive dyes from synthetic solution. Different parameters such as pH, time, temperature, agitation rate and various carbon, nitrogen and inorganic salts source, were optimized for decolorization of reactive blue 19 and reactive black 5 dyes. Aspergillus niger showed maximum dye decolorization under optimum condition and found to be more efficient when added in the dye solution of pH 8 and 10 with agitation at 130 rpm and incubation time for 7 days with 25°C.

The present study was undertaken on 60 adult female Sprague Dawley rats (275±2.04 g) for an experimental duration of 84 days to evaluate various organic sources of zinc on immunity, reproduction, oxidative defense mechanism in rats. The rats were randomly allotted to 5 dietary treatments (6 replicates in each) prepared by varying the source of Zn supplementation (12 ppm) either from inorganic (Zn carbonate) or sources (Zn proteinate, Zn propionate, Zn amino acid complex and Zn methionine).

Starch is the most abundant carbohydrate from the plant source.In different food processing sectors starch plays a vital role, includes thickening, gelling, consistency and shelf stability in various food applications. Irradiation plays an important role on the starch modification, it improves the viscosity of starch and plays a key role in the pasting properties. Irradiation dose was positively correlated to solubility and negatively correlated with relative crystallinity, thermal properties, and pasting properties.

CO2 -rich natural gas sources are popular in Vietnam, with their CO2 contents in the range of 10 - 60 mol%. Based on various CO2 contents of natural gas sources, a certain number of technologies are recommended for their wise uses. If the gas contains less than 10 mol% of CO2 , it can be used where urea production. In the case where its CO2 content is up to 25 mol%, methanol and dimethyl ether (DME) production could be considered. Gas with CO2 content of up to 50 mol% could be a good feedstock for carbon nanotube (CNT) production.
