Physico-chemical characterization of seed oils extracted from oranges (Citrus sinensis)
This study aimed to characterize the seeds of oranges, varieties Hamlin, Natal, Pera-rio and Valencia, on the composition and physico-chemical properties of its oil through the determination of free fatty acids, peroxide ...
Role of residual stress on phase transformations of Pb(Zr0.50Ti0.50)O3 thin films obtained from chemical route
abstract: The effects of heat treatment on the phase transformations of lead zirconate titanate Pb(Zr0.50Ti0.50)O3 (PZT) thin films were studied. The pyrolysis temperature directly affected the densification, residual ...
Chemical analysis and biorefinery of red algae Kappaphycus alvarezii for efficient production of glucose from residue of carrageenan extraction process
Background: Biorefineries serve to efficiently utilize biomass and their by-products. Algal biorefineries are designed to generate bioproducts for commercial use. Due to the high carbohydrate content of algal biomass, ...
