T-carbon, a new carbon allotrope, was initially predicted to exist in a theoretical study [Phys. Rev. Lett. 106 (2011) 155703] and successfully fabricated in recent experiment [Nat. Commun. 8 (2017) 683]. This work investigates the mechanical behaviors and structural evolution of T-carbon nanowires under tensile loading by using molecular dynamics simulations. It is found that T-carbon nanowires exhibit...
The data storage performance, stability and reliability of the graphene memories have advanced significantly towards practical information storage applications. Using highly dispersed 4-bromobenzene functionalized RGO (BB-RGO) as two dimensional template, a new poly[(1,4-diethynylbenzene)-alt-boron dipyrro-methene]-grafted reduced graphene oxide (PDBD-g-RGO) was synthesized via Sonogashira coupling...
This paper investigates the interface thermal conductance G and interface thermal rectification R of hybrid GE/SE monolayers via molecular dynamic simulations. The results show that G not only increases with the temperature but also with the monolayer length at a given temperature until it reaches a saturated value. At 300K, the saturated value is found to be ∼250MW/m2K. In contrast, R decreases with...
High pressure Raman, IR and X-ray diffraction (XRD) studies have been carried out on C 70 (Fe(C 5 H 5 ) 2 ) 2 (hereafter, “C 70 (Fc) 2 ”) sheets. Theoretical calculation is further used to analyze the Electron Localization Function (ELF) and charge transfer in the crystal and thus to understand the transformation of C 70 (Fc) 2 ...
We used a two-layer structure consisting of polyethylene terephthalate (PET) and silicone to transfer graphene grown by chemical vapor deposition onto various rigid and flexible substrates through dispersive adhesion. It only takes a few seconds to transfer graphene from PET/silicone to the target substrates at ambient conditions. And the recycling of the PET/silicone decreases the production cost...
Multi-walled carbon nanotubes covalently functionalized with tetraphenylporphyrin (MWCNT–TPP) with diameter ranges of <10, 10–30 and 40–60nm were prepared by the reaction of MWCNTs with in situ generated porphyrin diazonium compounds. The fluorescence quenching data show that the unique direct linkage mode facilitates the effective photoinduced electron transfer between the excited porphyrin moiety...
Five nanoporous carbons (NPCs) were prepared by polymerizing and then carbonizing carbon precursor of furfuryl alcohol accommodated in a porous metal–organic framework (MOF-5, [Zn 4 O(bdc) 3 ], bdc=1,4-benzenedicarboxylate) template. The Brunauer–Emmett–Teller (BET) surface areas for five NPC samples obtained by carbonizing at the temperatures from 530 to 1000°C fall into the range...
