文摘:四種羧酰化甲殼素即乙酰化、丙酰化、丁酰化和己酰化甲殼素在二氯乙酸溶液中均呈現膽甾型溶致液晶相.臨界濃度隨側基長度增加而略有增加,衍生物的臨界濃度明顯都比原甲殼素高許多,這些規律都可以用鏈剛性的變化來解釋.四種羧酰化甲殼素在剪切時均能形成條帶織構,而且能形成條帶織構的最低濃度有明顯差別,隨側基長度增加而提高,進一步表明側基較長,液晶性減少They immersed a lead object first in copper acetate ( a compound made by letting vinegar corrode copper ), and then in a silver solution created by dissolving silver chloride in dilute ammonia ( which ancient chemists made from urine )

研究表明:電解液的配製過程中,氯化釕濃度、溶液ph值、陳化時間、溶液溫度對電鍍效果均有影響,其中溶液ph值是最主要的影響因素;在儀器的使用條件探索中,理論結合實驗確定了本電鍍液體系循環伏安電勢窗的理想范圍,並發現循環伏安掃描速度和掃描周期對電鍍結果也有較大影響;混合氧化物的共沉澱是目前研究熱點,在此選用與釕同一族的銥作為共沉澱元素,銥的加入會阻礙氧化物的沉積速度,銥的比例超過50 %會使沉積作用停止,但是二元氧化物的協同作用使沉積的活性物質比容量大大提高;一定溫度下退火后處理作用會使水合釕化物轉變成混合價態的氧化釕,從而提高活性物質的穩定性。Results indicated that hrp could effectively oxidate pcp in aqueous solution. factors, such as acidity, temperature, enzyme activity, and initial concentration of pcp and h
