In this paper, the xLiFePO4.yLi3V2(PO4)3/C composite cathode materials were prepared via sol-gel method in order to combine the outstanding performance of L
重结晶烧结SiC需要不同颗粒粒径SiC的混合,粒径相差比较大的SiC在水基悬浮液中很难达到良好的分散,要制备出满足注浆成型要求的低粘度浆料,必须对影响SiC浆料流变性能的
Hydrogen detection has fundamental significance.Optical type sensor has a favorable prospect of development because of its Security and Sensitivity.In our w
A surfactant assisted sol-gel process was adopted to synthesize Li2ZnTi3Os nanopowders, which was then used to prepare dielectric ceramics.The size and size dis
综合实践活动的终极目标,要求综合实践活动课程设计要“全程化”,也就是说课程设计要注重动态性和发展性.通过全员合作,为“全程化”动起来注入满满活力;全面合作,为“全程化
我们的小城已经变了,只有围绕它的大海一如既往.不少新房子拔地而起,有些街道铺上了柏油路面,街角也装了红绿灯.城中有了两三家接待游客的高档酒店,到邻近的城市去也不再像过
The increase of partial pressure of CO2 in airproof room caused by staffs breath or any other reasons is really bad to peoples health.Adsorption has been an ide
针对三维纤维预制件的结构特点，为充分发挥其增强效果，采用高固相含量的Al2O3-SiO2双相溶胶为原料，通过浸渍-干燥-烧结制备三维碳纤维增强(Al2O3-SiO2)复合材料。本文以三维
类石墨状氮化碳(g-C3N4)因其特殊的物理化学性能,在太阳能利用、环境保护等领域显示了良好的应用前景,己引起广泛关注[1,2].g-C3N4能隙约为2.7 eV,制备简单,且化学稳定性
Ruddlesden-Popper(RP)系列的层状氧化物材料具有良好的氧扩散性能、电化学活性以及与电解质材料匹配的热膨胀系数(TEC).但如果要作为中低温的氧电极材料，还必须提高其中
