Nitrogen-doped porous carbon nanosheets as both anode and cathode for advanced potassium-ion hybrid capacitors

Green Energy & Environment, 2023
Potassium-ion hybrid capacitors (PIHCs) as a burgeoning research hotspot are an ideal replacement for lithium-ion hybrid capacitors (LIHCs). Here, we report nitrogen-doped porous carbon nanosheets (NPCNs) with enlarged interlayer spacing, abundant ...

Boosted molecular mobility during common chemical reactions

Science, 2020
Reactions give solvents a kick During a chemical reaction, the reorganization of solvent molecules not directly in contact with reactants and products is normally viewed as a simple diffusion response. Wang et al.

Modelling chemical reactions using semiconductor quantum dots [PDF]

, 2007
We propose using semiconductor quantum dots for a simulation of chemical reactions as electrons are redistributed among such artificial atoms. We show that it is possible to achieve various reaction regimes and obtain different reaction products by ...

Femtosecond X-ray solution scattering reveals that bond formation mechanism of a gold trimer complex is independent of excitation wavelength

Structural Dynamics, 2016
The [Au(CN)2−]3 trimer in water experiences a strong van der Waals interaction between the d10 gold atoms due to large relativistic effect and can serve as an excellent model system to study the bond formation process in real time.

Progress in understanding the four dominant intra-particle phenomena of lignocellulose pyrolysis: chemical reactions, heat transfer, mass transfer, and phase change

Green Chemistry, 2019
Four principal intra-particle phenomena occur in a highly concerted manner during the pyrolysis of lignocellulosic materials: heat transfer, mass transfer, chemical reactions, and phase changes.
