Carbon nanodots (CDs) are a new class of zero-dimensional, discrete and almost spherical carbon nanomaterials with sizes below 10 nm.Compared with those heavy-metal-based quantum dots, CDs have the su
We developed a graphene oxide (GO) and label-free aptamer based method for the fluorescence turn-on sensing of adenosine combined with exonuclease I (Exo I).This nearly universal biosensor approach is
We explore the interactions between a fluorescein (FAM) labeled guanine(G)-rich oligonucleotide sequences (P), graphene oxide (GO) and a cationic conjugated polymer, poly [(9, 9-bis (6-N, N, N-trimeth
In this work, different effects of substrates on the morphologies of single-walled carbon nanotubes (SWNTs) are studied.SWNTs were produced by floating catalytic chemical vapor deposition using CH4 as
Graphene and its derivatives have been regarded as the next-generation material for flexible nanoelectronic devices and one of the next-generation fillers for polymer nanocomposites to improve the mec
ZnO was synthesized on Si (100) substrate coated with vertical graphene (VG) by magnetron sputtering method.VG-ZnO nanocompositos were obtained with different morphology by controlling the preparation
富锂层状正极材料是一种新型的锂离子电池正极材料,因其具有理论容量高(>200mAh/g)、低成本、充放电电压高(>3.5V vs Li/Li+)等优点,已广泛成为人们的研究热点[1-2].Kim等[3]通过共沉淀法合成了0.3Li2MnO3·0.7LiMn1-xNiyCo0.1O2(x=0.3,y=0.2),2.0~4.6 V时放电容量为200 mAh/g;Kang等[4]采用溶胶凝胶法合成了0.
