Chemically converted graphene aerogels with ultralight density and high compressibility are prepared by diamine-mediated functionalization and assembly, followed by microwave irradiation. The resulting graphene aerogels with density as low as 3 mg cm(-3) show excellent resilience and can completely recover after more than 90% compression. The ultralight… (More)
Mitogen-activated protein kinase-activated protein kinase 2 (MK-2) has been identified as a drug target for the treatment of inflammatory diseases. Currently, a series of thiourea analogs as potent MK-2 inhibitors were studied using comprehensive computational methods by 3D-QSAR, molecular docking and molecular dynamics simulations for a further improvement… (More)
Currently, Chemoinformatic methods are used to perform the prediction for FBPase inhibitory activity. A genetic algorithm-random forest coupled method (GA-RF) was proposed to predict fructose 1,6-bisphosphatase (FBPase) inhibitors to treat type 2 diabetes mellitus using the Mold(2) molecular descriptors. A data set of 126 oxazole and thiazole analogs was… (More)
Boron-doped graphene, synthesized by annealing a mixture of graphite oxide and B2O3, has shown a high conversion efficiency of 6.73% as a counter electrode (CE) for dye-sensitized solar cells, which is better than the Pt CE.
Triple-walled carbon nanotubes (TWNTs) with three concentric cylindrical graphene layers have been selectively synthesized for the first time from decomposition of ferrocene encapsulated inside double-walled carbon nanotubes, and were identified by high-resolution transmission electron microscopy (HRTEM) and Raman spectroscopy; HRTEM observations reveal… (More)
Intermolecular dihydrogen bond O-H···H-Ge in the electronically excited state of the dihydrogen-bonded phenol-triethylgermanium (TEGH) complex was studied theoretically using time-dependent density functional theory. Analysis of the frontier molecular orbitals revealed a locally excited S(1) state in which only the phenol moiety is electronically excited.… (More)
Nitrogen-doped graphene nanoribbon aerogels (N-GNRAs) are fabricated through the self-assembly of graphene oxide nanoribbons (GONRs) combined with a thermal annealing process. Amino-groups are grafted to the surface of graphene nanoribbons (GNRs) by an epoxy ring-opening reaction. High nitrogen doping level (7.6 atm% as confirmed by elemental analysis) is… (More)
Biomass-derived carbon materials, as one type of promising anode material for lithium ion batteries (LIBs), have demonstrated intrinsic potential and superiority. Here, we report a facile and efficient approach to fabricate micro-sized porous carbon spheres (PCSs) by an integrated procedure of enzymolysis, pre-oxidation, and carbonization. Benefiting from… (More)
Well-defined carbon polyhedrons with faceted morphologies and hollow internal structures made of self-organized multi-walled carbon nanotubes have been fabricated by gas phase catalytic CVD inside microchannels, of which the confined space is critical for the formation of polyhedral structures with hexagonal, heptagonal and octagonal cross-sections that… (More)
This work reports an efficient strategy to synthesize B,N-codoped porous carbons with a high specific surface area using chitosan as the carbon precursor with the help of boric acid, featuring a high specific capacitance, large operation voltage and excellent cycle stability for supercapacitors.
