Flocculation of oxides using polyethylene oxide
Powder Technology, 1990 Abstract Flocculation of oxides using polyethylene oxide was investigated. Polyethylene oxide adsorbed strongly on and flocculated sodium kaolinite. H-bonding is considered to be the driving force for polyethylene oxide adsorption on kaolinite. The mechanism of adsorption of polyethylene oxide on kaolinite was examined by studying the adsorption ...

FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Ultraviolet Oxidation of Polyethylene
Kobunshi Kagaku, 1965 分岐度および二重結合量の異なる高圧法, 中圧法, 低圧法ポリエチレンフィルムに254, 316, 336, 354, 380mμ にそれぞれ主波長をもつ光源を使用して紫外照射を行ない, 紫外線酸化における波長依存性について赤外線吸収スペクトル, 密度および結晶化度, Melt flow rate, 不溶解分の測定を行なって検討した。その結果, 低エネルギー紫外線により結合エネルギーの小さい二重結合に対するβ位のC-H結合が攻撃され, 高エネルギー紫外線により分岐部のtertiary C-H結合も攻撃されることを確認した。また, 高エネルギー紫外線により高圧法ポリエチレンは橋かけ反応が, 中圧法, 低圧法ポリエチレンは切断反応が優先することを認めた。
