Graphitic carbon is currently considered the state-of-the-artmaterial for the negative electrode in lithium ion cells, mainly due to its high reversibility and low operating potential. However, carbon anodes exhibit mediocre charge/ discharge rate performance, which contributes to severe transport-induced surface structural damage upon prolonged cycling and limits the lifetime of the cell. Lith...

Reactive molecular dynamics simulations are used to study the initial stage of pyrolysis of phenolic polymers with carbon nanotube and carbon fiber. The products formed are characterized and water is found to be the primary product in all cases. The water formation mechanisms are analyzed and the value of the activation energy for water formation is estimated. A detailed study of graphitic prec...

The wet-chemical synthesis of hollow graphitic spheres, a highly defined model catalyst support for electrocatalytic processes, is laborious and not scalable, which hampers potential applications. Here, we present insights into the chemical vapor deposition (CVD) ferrocene as simple, scalable method to synthesize spheres (HGScvd). During CVD process, iron carbon are embedded in pores mesoporous...

Mesoporous silica nanoparticles (MSNs) were used as a nano-carrier/amplifier to develop a novel MSN-SERS probe for DNA MTase detection. High sensitivity, good selectivity, and rapid analysis are achieved.

The Gardnos impact structure in southern Norway is one of only two known impact structures (among 175) whose impactites contain significant amounts (typically 0.2–1.0 wt.%) of carbon, or 5 to 10 times the amount present in the target rocks; Sudbury, Canada is the other. This study extends a previous investigation of the geochemistry and petrology of Gardnos impactites (French et al., 1997) with...

A novel design and facile synthesis process for carbon based hybrid materials, i.e., cobalt monoxide (CoO)-doped graphitic porous carbon microspheres (Co-GPCMs), have been developed. With the synthesis strategy, the mixture of cobalt gluconate, α-cyclodextrin and poly (ethylene oxide)₁₀₆-poly (propylene oxide)₇₀-poly (ethylene oxide)₁₀₆ is treated hydrothermally, followed by pyrolysis in argon....

Supercapacitors with holey graphitic carbon nano-flakes (HGCNF) capable of demonstrating large specific capacitance (SC) have been developed for the first time. The unique approach applying an additional conducting layer fabric (CF) coated HGCNF at both half-cells provides a significant enhancement in SC, from 323 to 1142 F g?1, half cell and 8 487 g?1 symmetric supercapacitor, when architectur...
