Cu–CeO2 nanocomposites: mechanochemical synthesis, physico-chemical properties, CO-PROX activity

Physico Chemical Properties and Antioxidant Activity of Roselle Seed Extracts

The aim of this research was to extract phenolic compounds from defatted Roselle (Hibiscus sabdariffa L.) seed and assess their antioxidant potential. Water, ethanol (30%), methanol (30%) and acetone (30%) were used as solvent for extraction. The proximate composition, total phenolic content and extraction yield were analyzed. Antioxidant efficacies of Roselle seed extract were tested by using ...

Mechanochemical Synthesis of Magnetite/Hydroxyapatite Nanocomposites for Hyperthermia

synthesis and physico-chemical properties of a series of bidentate

transfusion-dependent patients such as those suffering from β-thalassaemia develop a fatal secondary haemosiderosis and consequently a selective iron chelator must be used to relieve such iron overload. 3- hydroxypyridin-4-ones are selective for iron(iii) under most biological conditions, but unlike desferrioxamine, are efficiently absorbed when administered orally. in this study, the synthesis...

Physico-chemical Properties of Sweeteners in Confections

Sugars and other sweeteners are often the main components of a confection. Besides making them sweet, they also provide bulk to the candy. However, the physico-chemical properties of the sweeteners do more than just provide bulk. The physical characteristics of a candy, which include consistency, chewy or stretchy characteristics, melt-in-the-mouth behavior, flavor release, and many other prope...

Physico-chemical properties of lactic dehydrogenase.

Although the mechanism of the enzymatic reaction catalyzed by lactic dehydrogenase has been investigated by several workers, little work has been reported on the physical chemistry of this protein. In particular, a precise value for the molecular weight has not been reported. Meister (1) has estimated the molecular weight to be of the order of 100,000 to 150,000. Neilands (2) has reported a val...
