The need for environmental education, which incorporates the life cycle concept into the learning program, will become increasingly greater all over the world.
锂离子电池由于具有高能量密度、高比容量和长循环寿命等优势作为一种理想的储能装置,被广泛的应用于电子移动设备和电动汽车。商业化的石墨负极材料理论容量低,仅有372 mAh g-1,而且导电性较差,锂离子扩散系数较低,从而进一步限制了其在高性能锂离子动力电池中的应用。本论文主要利用溶剂热和脱合法制备了二元过渡金属氧化物CoFe_2O_4和NiFe_2O_4纳米多孔球、分层的Co_3O_4(h-Co_3
In this current paper, the exposure time effects on four endocrine disruptors and teleost fishes were evaluated using the reduced life expectancy (RLE) model ba
