Metal-catalyst-free growth of single-wall carbon nanotubes(SWCNTs)has attracted lots of attention recently,aiming for structure and property-controlled synthesis of SWCNTs.In this talk,we will report
Each chiral single-wall carbon nanotube(SWCNT)has a pair of optical isomers(i.e.,left-and right-handed structures),which exhibit different optical activities and have potential applications in optical
All Single-and few-layer graphene have emerged as interesting 2D systems for the investigation of novel integer and fractional quantum Hall states.Recently clear fractional quantum Hall states in bi-l
During the last decade focused ion beam(FIB)processing has become an essential tool for sub-surface(3D)metrology and the site specific fabrication of ultrathin lamellas suitable for transmission elect
Carbon nanodots(CNDs)are small(1–10 nm)surface-passivated carbon nanoparticles[1],emitting photoluminescence(PL)across the entire visible light range.Since their first description in 2004[2],CNDs have
As is known to all,graphene oxide(GO)is amphipathic for the hydrophilic edges and hydrophobic basal plane.And with the decrease of the lateral dimension size,the hydrophility would be significantly im
Semiconducting single-walled carbon nanotubes(sc-SWCNTs)have been regarded as one of ideal materials to fabricate high-performance thin film transistors(TFTs)and circuits due to their flexibility,high
Two-dimensional(2D)group VIB transition-metal dichalcogenides(TMD)have attracted broad interests.While group IVB TMDs,such as ZrX2,HfX2(X=S,Se,Te),have rarely been studied but can have superior electr
With the commercial application of graphite anode,lithium-ion batteries(LIBs)are extensively applied in numerous portable devices such as smartphones and laptops.However,current LIBs based on conventi
It is generally believed that cytotoxicity of QDs mostly comes from the release of toxic heavy metal ions(e.g.,Cd 2+,Pb 2+),which is largely dependent on the stability of outer surface layers.For exam
