Growth of unsaturated, cyclic, and polycyclic aromatic hydrocarbons: Reactions under the conditions of the interstellar medium
… reactions between cationic PAHs/hydrocarbons and methyne (CH) were investigated. The reaction type and the precursor were derived and selected from known chemical and physical properties of the ISM. These chemical reactions were characterised by calculating branching ratios (based on cross …

Production of biodegradable poly lactic acid from pineapple industry wastewater by lactobacillus casei fermentation
… was due to CH stretching of the methylene and methyne groups, a range 1716 to 1748 for ester carbonyl group; other significant bands are in region 1118-1360 typical for ester group -CO-O. A clear glass transition (Tg)at 45.3 °C was exhibited when heat synthesis at 160°C. The results obtained …
