Organometallic reagents in the syntheses of natural compounds

Asymmetric copper-catalyzed conjugate additions of organometallic reagents in the syntheses of natural compounds and pharmaceuticals. Access to enantiopure complex molecular structures is crucial for the development of new drugs as well as agents used in crop-protection. In this regard, numerous asymmetric methods have been established. Copper-catalyzed 1,4-additions of organometallic reagents are robust C-C bond formation strategies applicable in a wide range of circumstances. This review analyses the […]

Conditioning Landfill Sludge With Ferric Chloride And A Fenton Reagent

Insight into conditioning landfill sludge with ferric chloride and a Fenton reagent: Effects on the consolidation properties and advanced dewatering The landfill sludge in storage reservoirs needs to be dewatered and disposed of for environmental and engineering purposes. The key factors are the high organic matter content and low permeability. Chemical conditioning is considered an efficient method for adjusting the properties of sludge. In this […]

Treatment of Polymers Enables Reagent-Free Covalent

Atmospheric Pressure Plasma Jet Treatment of Polymers Enables Reagent-Free Covalent Attachment of Biomolecules for Bioprinting 3D bioprinting, where cells, hydrogels and structural polymers can be printed layer by layer into complex designs, holds great promise for advances in medicine and the biomedical sciences. In principle, this technique enables the creation of highly patient specific disease models and biomedical implants. However, an ability to tailor surface biocompatibility […]

High density lipoprotein phospholipid using a sensitive reagent 

Enzymatic determination of high density lipoprotein phospholipid using a sensitive reagent and a Cobas Bio Centrifugal Analyzer. A sensitive enzymatic method for the measurement of high density lipoprotein choline-containing phospholipids (HDL-pc) was adapted to a Cobas Bio Centrifugal Analyzer. The Boehringer Mannheim phospholipase D/choline oxidase/peroxidase reagent was modified by the inclusion of 2,4,6,-tribromo-3-hydroxybenzoic acid (TBHBA) which reacts with hydrogen peroxide and 4-aminophenazone to produce a quinone-imine dye with […]

Ehrlich’s bio-reagent oxidation over enzyme mimic

Colorimetric willpower of F-, Br- and I- ions by Ehrlich’s bio–reagent oxidation over enzyme mimic like gold nanoparticles: Peroxidase-like exercise and multivariate optimization. Citrate and polyvinyl alcohol capped gold nanoparticles (PVA-GNPs) had been synthesized by way of chemical discount method and totally characterised by DLS, SEM, EDS, XRD, UV-Vis and FT-IR evaluation. A easy and sensible colorimetric sensor based mostly on red-ox response of p-dimethylaminobenzaldehyde (DABA) […]
