Benzoyl Peroxide Decomposition by Nitrogen-Containing Carbon Nanomaterials

Tretinoin and Benzoyl Peroxide

A simple, sensitive, spectrophotometric method in UV region has been developed for the simultaneous estimation of benzoyl peroxide and tretinoin in bulk and semi solid dosage form (cream). Standard solution of benzoyl peroxide shows maximum absorbance at 234.8 nm and tretinoin shows maximum absorbance at 348.6 nm. Beer’s Lamberts law is obeyed in concentration range 1-9 μg/ml for tretinoin with...

MATERIALS CHEMISTRY COMMUNICATION Nitrogen-containing carbon nanotubes

could be prepared by employing appropriate precursor molecules. Nanotubes containing both boron and nitrogen have Carbon nanotubes containing small amounts of nitrogen are been grown in the electric arc discharge between graphite produced by the pyrolysis of aza-aromatics such as pyridine, cathodes and graphite anodes filled with boron in a nitrogen methylpyrimidine and triazine over cobalt nan...

Nitrogen-Containing Carbon Nanotubes - A Theoretical Approach

Oxygen Adsorption on Nitrogen Containing Carbon Surfaces

Introduction The reaction of O2 with carbonaceous surfaces has been widely studied due to its important application in industry. In general, O2 is first chemisorbed on an electron-rich site of the carbon basal plane of graphite and then, it dissociates into oxygen atoms. Oxygen will diffuse on the surface until finds a structural defect to form covalent bonds. If temperature is appropriated, CO...

Poly(lactic acid) Composites Containing Carbon-Based Nanomaterials: A Review

Poly(lactic acid) (PLA) is a green alternative to petrochemical commodity plastics, used in packaging, agricultural products, disposable materials, textiles, and automotive composites. It is also approved by regulatory authorities for several biomedical applications. However, for some uses it is required that some of its properties be improved, namely in terms of thermo-mechanical and electrica...
