Among transitional metal oxides,nano NiO is one of the relatively few metal oxides with p-type semiconductivity,which has stable and wide band gap.

纳米氧化镍是过渡金属氧化物中不多见的p型半导体之一,具有稳定而较宽的带隙,作为一种新型功能材料受到人们关注。

Autoxidation of lipids is a chain raction of free radical.In the inducing stage,the inducers switching on free radical may be lipoxygenase or photoxidation,but the most is transitional metals.

脂类的自动氧化是一个自由基连锁反应，诱导期中启动自由基的诱发剂可能是脂氧酶、光氧化，但多数为过渡金属离子。
