Recently, the biomass "bottom-up" approach for synthesis of graphene quantum dots (GQDs) has attracted broad interest because outstanding features, including low-cost, rapid, and environmentally friendly nature. However, low crystalline quality products, substitutional doping with heteroatoms in lattice, ambiguous reaction mechanism strongly challenge further development this technique. Herein, we proposed a facile effective strategy to prepare controllable sulfur (S) GQDs, occurring lattice...
Abstract Those responsible for the development of sonosensitizers are faced with a dilemma between high sonosensitization efficacy and good biosecurity that limited sonodynamic therapy (SDT). Herein, inspired by intriguing therapeutic features SDT potential catalytic activity graphene quantum dots, N‐doped dots (N‐GQDs) to act as sonosensitizer is demonstrated. The superior effect N‐GQDs believed be three five times higher than traditional (such porphyrin, porphyrin Mn, Zn, TiO 2 , etc.)....
Abstract Studying the phosphorescent mechanisms of carbon nanostructures synthesized by “bottom‐up” approach is key to understanding structure modulation and interfacial properties nanostructures. In this work, relationships among symmetry precursors in synthesis, structures products, phosphorescence lifetimes graphene quantum dots (GQDs) are studied. The matching formation a D 6h graphene‐like framework considered factor controlling separability sp 2 domains GQDs. As GQDs increases,...
Directly synthesize vertical graphene nano-petals (VGNPs) on SiO<sub>2</sub> substrate by PACVD, the growth temperature is significantly reduced and reaches at 550 °C. We utilize unique topography of VGNPs to investigate ammonia gas sensitivity realize ppt level detection ability.
Tunable photoluminescence performance of graphene quantum dots (GQDs) is one the most important topics for development GQDs. In this paper, we report lattice-doped GQDs (boron-doped (B-GQDs) and phosphorus-doped (P-GQDs)). Because matched band structure, fast energy transfer between blue-emitted B-GQDs (emission wavelength: 460 nm) orange-emitted P-GQDs 630 can induce an efficient fluorescence emission in once are excited under optimal excitation wavelength nm. Moreover, with effective...
The evaluation of intracellular reactive oxygen species (ROS) would greatly deepen the understanding cell metabolism/proliferation and tumor detection. However, current long-acting level tracking techniques for ROS remain unsuited to practical applications. To solve this problem, we synthesized cyclotriphosphazene-doped graphene quantum dots (C-GQDs) whose yield is highly sensitive (increased by 400% from 0.12 0.63). Electron cloud polarization oxidized cyclotriphosphazene rings in C-GQDs...
Vertical few layered graphene (VG) nanoflakes were directly synthesized on traditional glass substrate by the plasma-assisted chemical vapor deposition, where extremely low growing temperature (<560 °C) and short time (<30 min) involved. The VG microstructure could be well-controlled tuning plasma power, growth temperature. Raman, TEM, SEM used to determine quality single size of VG. Because unique three-dimensional structure with high surface area, network can provide superior thermal...
Environmentally responsive cotton fabrics were fabricated by dip-coating ABC miktoarm star terpolymers, which contain reactive poly(3-triisopropyloxysilylpropyl methacrylate) blocks, hydrophobic poly(dimethylsiloxane) (PDMS) and hydrophilic poly(N,N-dimethylaminoethyl (PDMAEMA) blocks. The functionalized with perfectly alternating PDMS PDMAEMA blocks show underoil superhydrophobicity underwater superoleophobicity. wettability permeability of the can be readily adjusted contacting medium....
