Magnetic 3D nitrogen doped graphene gels (MNG) were easily obtained via one-pot hydrothermal synthesis process. It was found that N doping process, reduction of graphene oxide and Fe"3O"4 nanoparticles (NPs) generation in situ proceeded simultaneously, accompanied by the three-dimensional self-...
In summary, worm-nest-like nanocarbons with rich nitrogen functionalities were fabricated by a role-divided templating and doping strategy, in which MgO first serves as catalyst for phenol and formaldehyde polymerization to form a resin, and then as template for the generation of worm-nest-like ...
graphenesilicon‐dopingmolecular sensingdensity functional theoryOn page 7593, R. T. Lv, M. Terrones, and co-workers demonstrate that Si-doped graphene can be used as an efficient substrate to identify fluorescent molecules by Raman spectroscopy using laser beams (shown in green). The image shows...
This causes 2D materials to act as metallic layers, and an ion implantation technique with precise doping controllability is not available for these materials (e.g., MoS2, MoSe2, WS2, WSe2, graphene). Since adjustment of the electrical and optical properties of 2D materials is possible within...
doping. However, the weak coupling between moments in Cu can not survive at room temperature. The fall of ferromagnetism in the 5 × 1015 cm−2sample can not be understood with Cu doping, either. Considering that the implantation also creates defects in graphene, this result may be ...

graphene/CsPbBr3heterojunction and the natural middle energy band in graphene nanowalls extend the carrier lifetime. Therefore, a long half-life period of photocurrent decay - 35.59 s has been achieved. Moreover, the long-term optoelectronic response can be controlled by the adjustment of numbers,...
A facile strategy to construct the N-enriched hierarchically porous carbon nanosheets was developed while the bis-vinylimidazolium based poly(ionic liquids) (PIL-Ac) served as ideal carbon precursors and zinc acetate (Zn (Ac)(2)) as a potent template based on Zn(Ac)(2)/PIL-Ac coordination ...
In this paper, we carry out a theoretical investigation on the population dynamics of graphene system under continuous-wave (cw) laser and chirped pulse excitation. Results of our numerical simulations reveal that complete population transfer from an initially occupied ground state to the initially uno...
