Improving the Vertical Thermal Conductivity of Carbon

However, thermoplastic resins with low thermal conductivity limit the commercialization of the CFRP as a polymer matrix for composites [13,14]. Composites with low thermal conductivity do not dissipate heat quickly but accumulate heat, which causes deterioration of the mechanical properties due to peeling between the carbon fiber and the polymer matrix of the composite.

XIAOJIA ZHANG

Here, we present a newly designed, highly flexible transparent conductive electrode based on a copper sulfide nanotrough network (CuS NN) film. This electrode achieves the sheet resistance of 20 Ω/sq with a transmittance of up to 80%, which is produced by a process involving electrospinning, metal deposition and low temperature solvothermal reaction.

Scientific Challenges for the Implementation of Zn

Zn-ion batteries are frequently cited with promising metrics for a myriad of applications including stationary storage. However, fundamental aspects of their chemistry, which may hinder commercialization, have been largely overlooked in the recent literature. In this review, we focus on these aspects and provide guidance for future research, including the challenge of proton/Zn2+ co

Electrochemically exfoliating graphite into N

The voltage was kept constant for 12 h, and the expanded graphite electrode was calcined in N 2 atmosphere at 650 C for 3 h to produce N-doped graphite paper. Afterward, the obtained N-doped graphite paper was used as the working electrode, and then was further electrochemically exfoliated in ammonium sulfate electrolyte solution under the equal condition with the first exfoliation step.
