silicon core-shell structures for high-power supercapacitor electrodes S. A. Safiabadi Tali1,2, S. Soleimani-Amiri3, Z. Sanaee1,2 & S. Mohajerzadeh2 We report successful deposition of nitrogen-doped amorphous carbon films to realize high-power core- shell supercapacitor electrodes...
Generally, carbon electrodes (e.g., GC) exhibits relatively low 4-electron selectivity during the ORR and generates high peroxide yields, but this will greatly depend on carbon structure (e.g., morphology and graphitization degree) and nitrogen doping (e.g., total nitrogen content, doping posit...
The incorporation of electron-rich nitrogen atoms into the carbon architecture promotes the interaction between neighboring carbons and electrons, providing a superior heteroatom-doped catalyst23,26. Nitrogen-doped graphene is one of the most prom- ising candidates owing to its high chemical stability, ...
electron microscopy (SEM). Graphene sheet structures were abundant in the hybrid catalyst. Loading differences notwithstanding, the performance gap in terms of E1/2in RDE testing between the hybrid Fe—Co catalyst (600 μg/cm2) and Pt/C (60 μg-Pt/cm2) catalysts is approximately 35 mV in...
In this type of environment, energy is not the limiting factor for the development of the microbial community, as sulfur or iron minerals are abundant and can be used as electron donors. Therefore, carbon and/or nitrogen are likely the most limiting elements for the development of the ...
The lattice stripes of each component of the material can be clearly observed in the high-resolution transmission electron microscope image (Figure 4b). The lattice fringes of the carbon layer are 0.317 nm, corresponding to the graphite carbon (002) crystal plane, while the lattice stripe with ...

Conclusions In summary, the Co@NC series catalysts using different nitrogen sources were synthesized by a one-pot pyrolysis method. The catalysts’ characterizations demonstrated that the metallic Co...
Ultra-high resolution samples were analyzed using a hybrid 7 Tesla linear ion trap (LTQ) FT-ICR MS (LTQ FT Ultra, Thermo Electron, Woods Hole Oceano- graphic Institute Mass Spectrometer Facility) in the positive ionization mode. A larger number of N-con- taining compounds are found in the...
However, the poor electrical conductivity of T-Nb2O5 (~3.4×10−6 S cm−1 at 300 K) limits the electron transport, reducing rate capability and electrochemical utilization [17,18]. An effective method to overcome this issue is to introduce conductive carbon materials into the T-...
