A novel enzyme-based glassy-carbon electrode (GCE) was constructed by coating Nafion-graphene nanoribbon (GNR) biocomposite on the electrode surface and then immobilized glucose oxidase (GOD).The dire
Ultralong isolated single-walled carbon nanotubes (SWCNTs) were synthesized on the SiO2/Mo mesh to fabricate long individual suspended SWCNTs samples.We detected delicately temperature dependence Rama
Commonly, single-walled carbon nanotubes (SWCNTs) are catalytically grown from transition metal nanoparticles at a high temperature ranging from 700 to 1100 C, where metal catalysts are in liquid or p
We develop an experimental technique that is convenient for both chirality determination and transport measurements of carbon nanotubes, thus providing a way to explore the physical properties of carb
The chiral liquid crystal (CLC) phase of pristine graphene oxide have been disclosed recently, opening an avenue to high performance neat graphene fibers.Here, we report for the first time LC of polym
Charging of insulating substrates is a common problem during electron beam lithography (EBL) exposure, which deflects the beam and distorts the pattern.A lot of efforts have been done in order to over
Two-dimensional (2D) carbon nanosheets (CNSs), which consist of few-to multi-layer of graphene sheets, have attracted great interest in many fields because of their high surface area, high height/thic
A large amount of studies have already focused on the mechanisms of silk self-assembly and the nanoscale structure formation in silk-based biomaterials.However, there were several key issues should be
第三代锂离子电池的发展趋势是采用高容量的纳米硅负极以及富锂正极材料.纳米硅负极的主要问题是高容量带来的显著的体积膨胀,在电池工艺上带来较大的挑战,目前以限制电极容量的办法开始小范围应用.
实验通过溶剂热结合酯化反应合成了Co掺杂的一系列LiFe1-xCoxPO4/C (x=0,0.005,0.01,0.015,0.02 and 0.025)纳米片,乙二醇做溶剂.SEM显示所得样品为片状,经TEM显示所得纳米片在b轴方向很短,主要沿(101)晶面的[001]晶向生长,这样缩短了b轴长度,有利于锂离子扩散.电化学测试显示掺杂量为x=0.01的样品LiFe0.99Co0.01PO4/C展
