Linear allylic C-H oxidation: methods and utility
… complex functional groups through the use of C-H oxidation methodologies has the potential to dramatically increase the efficiency of synthetic sequences with respect to resources, time and overall steps to key intermediates. This work describes methods that target complex intermediates to show …

Molecular and isotopic records of combustion inputs to the environment over the last 250 years
… by a combination of chemical and/or thermal oxidation methods highlighted the limitations of these methods when applied to sedimentary matrices. Finally, parallel lead and cesium isotopic records revealed two new potential stratigraphic markers in North American sedimentary records. …

Nuclear respiratory factor 1: a novel inhibitor of the human gene promoter of the cardiac isoform of acetyl-coenzyme a carboxylase
… a potent inhibitor of CPT-1 and FA 13-oxidation. Since ACCl3 induction elevates malonyl-CoA levels, we hypothesised that AMPK activates NRF-1 thereby inhibiting ACCl3 expression in the heart to ultimately increase FA !3-oxidation. Methods: A 1,317 bp human ACCl3 gene promoter-luciferase …

Novel chemical and toxicological studies on textile industry waste streams clean up
… purify dye house effluents modem photochemical oxidation methods, such as the UV /hydrogen peroxide process, provide an effective treatment technology. Organic contaminants can be completely mineralised by this method but it is relatively expensive. Photochemical oxidation with subsequent …

Enhancing chemoselectivity and predicting site-selectivity in manganese catalyzed C–H oxidation
Recent advancements in Csp³–H oxidation methods have shown that even strong, oxidatively inert C–H bonds can be selectively oxidized in the presence of more oxidatively labile functional groups. Remarkably, these methods enable preferential oxidation of specific C–H bonds within complex substrates, …

High sensitivity DNA detection using gold nanoparticles and conducting polymers
… was obtained. Electrochemical detection of both methods was carried out through a suitable substrate (H2O2) for the enzyme labelled duplex. Polyaniline (PANI) has been synthesized by electrochemical, chemical and vapour oxidation methods. These PANI films have then been modified with …

Colorimetric sensor arrays with a pre-oxidation method for gaseous analytes
… To improve the array response, a disposable pre-oxidation technique has been developed in which a vapor stream is passed through an oxidation tube in front of the array. Oxidation byproducts (e.g., carboxylic acids, phenols, aldehydes, etc.) are reactive species that can be easily detected. Since …

Synthesis and characterisation of molecular nanostructures
… nanostructures. First, diverse chemical and oxidation methods for the purification of as-produced SWCNT were presented. Purified samples were investigated using TEM and OAS. The analysis of the optical absorption spectra in the UV-Vis energy range revealed that some of the chemical treatments …
