The disposal of voluminous, highly alkaline, bauxite residue (BR), the industrial by-product alumina production by Bayer process, constitutes an intricate global environmental problem. BR, containing valuable metals such as rare-earth elements (REEs)—in particular, scandium (Sc)—can be used a secondary source for REE extraction. scope this study was investigation bioleaching innovative and envi...
alismatis rhizoma decoction (ard) is a classical traditional chinese medicine (tcm) formula for treatment of vertigo with its long history of successful clinical effect. since vertigo is a symptom of hyperlipidemia, this study aimed at evaluating the hypolipidemic effect of ard in hyperlipidemia mice induced by high fat diet (hfd) and investigated the rationality of formula combination of alism...
background bedsore is one of the major problems in all the societies as patients are confined to bed. due to antibiotic resistant strains being a significant obstacle for cure, many plants and herbs are being used by researchers as medicinal compounds. objectives the investigation of synergistic effect of cellulose biopolymer and papaver macrostomum extract on bedsores bacterial community. mate...
UNLABELLED Graphene quantum dots (GQDs), a newly emerging 0-dimensional graphene based material, have been widely exploited in optoelectronic devices due to their tunable optical and electronic properties depending on their functional groups. Moreover, the dispersibility of GQDs in common solvents depending on hydrophobicity or hydrophilicity can be controlled by chemical functionalization, whi...
BACKGROUND Evidence-based best practices for incorporation into an optimal multilevel intervention for suicide prevention should be identifiable in the literature. AIMS To identify effective interventions for the prevention of suicidal behavior. METHODS Review of systematic reviews found in the Pubmed, Cochrane, and DARE databases. Steps include risk-of-bias assessment, data extraction, sum...
A set of supercritical extractions (SCE) using carbon dioxide (CO2) has been performed on Solanum nigrum Linn. design experiment (DoE) Box-Behnken was applied to investigate the influential parameters SCE. The relationship between extraction (i.e., temperature, time, and pressure) products phenolics-TPC, alkaloids-TAC, flavonoids-TFC) evaluated. It found that temperature pressure are most influ...
copper extraction from heap 3 low grade ore at sarchechmeh is limited due to its mixed composition (copper oxide and sulphide minerals). changing this heap to a bioheap could improve the copper recovery.
Polyprenols separated from lipids are promising new components from Ginkgo biloba L. leaves (GBL). In this paper, ginkgo lipids were isolated by extraction with petroleum ether, saponification, and molecular distillation. Eight known compounds: isophytol (1), nerolidol (2), linalool (3), β-sitosterol acetate (4), β-sitosterol (5), stigmasterol (6), ergosterol (7), β-sitosterol-3-O-β-D-glucopyra...
