An extremely simple and rapid (seconds) approach is reported to directly synthesize gram quantities of P-doped graphitic porous carbon materials with controlled P bond configuration. For the first time, it demonstrated that can be used as a selective metal free catalyst for aerobic oxidation reactions. The work function materials, its connectivity configuration, correlation catalytic efficiency are studied established. In direct contrast N-doped graphene, higher show high activity in...
Abstract Three strategies were proposed to prolong the service life of continuous fiber-reinforced silicon carbide ceramic matrix composite (CMC-SiC), which served as thermal-structure components aeroengine at thermo-mechanical-oxygenic coupling environment. As for some with low working stress, improving degree densification was crucial life, and related process approaches recited. If worked under moderate cracking stress ( σ mc ) should be improved far possible. The fiber preform...

Developing high-energy cathode for sodium ion batteries (SIBs) that enables 3-electron reaction is the most effective way to reduce high cost and solve range anxiety safety hazards. Here, a novel NASICON-type Na 4 MnCr(PO ) 3 (NMCP) synthesized as SIBs. The as-prepared 6.4 wt% carbon-coated NMCP (NMCP@C) annealed at 700 °C delivers discharge capacity of 107.3 mA h g −1 @0.1C, rate capability up 15C, well retention 69.3% after 500 cycles 5C within 1.4 ~ 4.3 V. Meanwhile, it also provides an...
Self-intercalation in two-dimensional (2D) materials is significant, as it offers a versatile approach to modify material properties, enabling the creation of interesting functional materials, which essential advancing applications across various fields. Here, we define ic-2D covalently bonded compounds that result from self-intercalation metal into layered 2D compounds. However, precisely growing with controllable phases and concentrations fully exploit family remains great challenge....

Abstract Rational design of hierarchically structured electrocatalysts is particularly important for electrocatalytic oxygen reduction reaction (ORR). Here, ZIF‐67 crystals are stringed on core–shell Ag@C nanocables using a coordination‐modulated process. Upon pyrolysis, strings Co nanoparticles embedded with three‐dimensional porous carbon beads‐on‐string hierarchical structures developed. Due to the advantages rich electrochemical active sites Co‐based “beads” and efficient electron...
Typical graphene field-effect transistors (GFETs) show ambipolar conduction that is unfavorable for some electronic applications. In this work, we report on the development of unipolar GFETs. We found titanium oxide situated surface induced significant hole doping. The threshold voltage p-type GFET was tunable by varying density attached through an etching process. An annealing process followed silicon nitride passivation to convert GFETs n-type air-stable complementary inverter integrated...
In this paper, graphene/mica and graphene/SiO2 based ammonia gas sensors are compared. It is found that adsorbed NH3 molecules result in up-shifting of the Fermi level graphene, leading to a significant increase graphene resistance. comparison with SiO2 supporting substrate, mica substrate induce more p-doping favour molecule adsorption, yielding high sensitivity. These findings suggest plays an important role mediating interaction between can be excellent underlying for detection.
