Simulation of Soot Formation in Pulverized Coal Combustion under O/N and O/CO Atmospheres.

In this study, simulations were carried out to study the combustion characteristics within a 600 MW W-shaped pulverized coal boiler under O/N and O/CO atmospheres. The objective of this work is to develop and validate a novel model for pulverized coal combustion under O-enriched conditions, specifically optimized for the O/CO atmosphere. The innovation in this model lies in the precise calibration of kinetic constants for soot nucleation and surface growth rates, enabling a more accurate simulation of flame characteristics (such as the flame temperature and soot volume fraction) under O-enriched combustion conditions.

Mung Bean Protein Hydrolysates Protect Mouse Liver Cell Line Nctc-1469 Cell from Hydrogen Peroxide-Induced Cell Injury.

Mung bean is nutritious and rich in protein (19.5%-33.1%).

Physico-chemical properties, antioxidant activities and angiotensin-I converting enzyme inhibitory of protein hydrolysates from Mung bean (Vigna radiate).

Mung bean Protein hydrolyses (MBPHs) have attracted a great deal of attention due to their variety of biological activities. In present study, MBPHs were fractionate according to the molecular mass into three fractions of MBPHs-I (<3 kDa), MBPHs-II (3-10 kDa) and MBPHs-III (>10 kDa). Their antioxidant activity and angiotensin-I converting enzyme (ACE) inhibitory of were investigated in vitro.

Physicochemical characterization, antioxidant activity of polysaccharides from Mesona chinensis Benth and their protective effect on injured NCTC-1469 cells induced by HO.

Polysaccharides MP-A, MP-U and MP-C were extracted from Mesona chinensis Benth by hot-alkali extraction (HAE), ultrasonic-assisted extraction (UAE) and cellulose-enzyme assisted extraction (CAE), respectively. The yields, physicochemical properties and antioxidant of polysaccharides were investigated. Results showed that the yields of MP-A (11.
