Background: This study was carried out to fully investigate the phenolic chemical constituents of Sarcopyramis nepalensis and determine their α-glucosidase inhibitory activity. Materials and Methods: S. nepalensis was extracted using the ultrasonic assistant extraction (UAE) method and further fractionated with petroleum ether (PE), chloroform (CHCl3), ethyl acetate (EtOAc) and n-butanol (n-BuO...

Thermal Protection Materials (TPM) such as carbon/phenolic composites are used to protect spacecraft structures from extreme conditions. This protection is, in part, achieved by the decomposition via pyrolysis of phenolic resin. Finite rate chemistry models however still unable predict chemical production rates and composition products accurately. is mostly due scarcity experimental data for mo...

With the rapid growth in the ethanol fuel industry in recent years, considerable research is being devoted to optimizing the use of processing coproducts, such as distillers dried grains with solubles (DDGS), in livestock diets. Because these residues contain high fiber levels, they may be amendable to incorporation into biobased composites. Thus, the goal of this study was to demonstrate the v...

FeIII supported on resin as an effective catalyst for oxidation was prepared and applied for the degradation of aqueous phenol. Phenol was selected as a model pollutant and the catalytic oxidation was carried out in a batch reactor using hydrogen peroxide as the oxidant. The influent factors on oxidation, such as catalyst dosage, H2O2 concentration, pH, and phenol concentration were examined by...

Two white wine extracts rich in phenolic acids, caffeic acid and gallic acid were tested as inhibitors of the decrease of linalool in Muscat wine. Each wine extract was added at 60 ppm and each phenolic acid at 40 ppm. Immediately after the addition of each wine extract or phenolic acid, no effect on the concentration of linalool was observed, but it decreased from the initial 470.9 to 223.3 μg...

There are three types of adhesion difficulties faced by the Babylon Tyre manufactured: bonding the inner liner to the fabric cord, bonding the tread to the breaker bandage, and bonding the sidewall to the bead apex. We have investigated the adhesion between layers of tyre by using maleic anhydride (MA) in an elastomer while using phenolic resin, resorcinol, or novolak in another elastomer to un...

Diet switching in mammalian herbivores may necessitate a change in the biotransformation enzymes used to process plant secondary compounds (PSCs). We investigated differences in the biotransformation system in the mammalian herbivore, Neotoma lepida, after a radical shift in diet and secondary compound composition. Populations of N. lepida in the Mojave Desert have evolved over the past 10,000 ...

Supported ionic liquid membranes (SILMs) have a promising prospect of application in flue gas separation, owing to its high permeability and selectivity of CO₂. However, existing SILMs have the disadvantage of poor stability due to the loss of ionic liquid from the large pores of the macroporous support. In this study, a novel SILM with high stability was developed by confining ionic liquid in ...
