The intrinsic nature of persulfate activation and N-doping in carbocatalysis.

Environmental Science and Technology, 2020
Persulfates activation by carbon nanotubes (CNT) has been evidenced as nonradical systems for oxidation of organic pollutants. Peroxymonosulfate (PMS) and peroxydisulfate (PDS) possess discrepant atomic structures and redox potentials, while the nature ...

Heteroatom Doping: An Effective Way to Boost Sodium Ion Storage

Advanced Energy Materials, 2020
In response to the change of energy landscape, sodium‐ion batteries (SIBs) are becoming one of the most promising power sources for the post‐lithium‐ion battery (LIB) era due to the cheap and abundant nature of sodium, and similar electrochemical ...

Se-Doping Activates FeOOH for Cost-Effective and Efficient Electrochemical Water Oxidation.

Journal of the American Chemical Society, 2019
Ni or Co is commonly required in efficient electrocatalysts for oxygen evolution reaction (OER). Although Fe is much more abundant and cheaper, full-Fe or Fe-rich catalysts suffer from insufficient activity.

Direct Pyrolysis of Supermolecules: An Ultrahigh Edge‐Nitrogen Doping Strategy of Carbon Anodes for Potassium‐Ion Batteries

Advances in Materials, 2020
Most reported carbonaceous anodes of potassium‐ion batteries (PIBs) have limited capacities. One approach to improve the performance of carbon anodes is edge‐nitrogen doping, which effectively enhances the K‐ion adsorption energy.

Doping of Carbon Materials for Metal‐Free Electrocatalysis

Advances in Materials, 2018
Carbon atoms in the graphitic carbon skeleton can be replaced by heteroatoms with different electronegative from that of the carbon atom (i.e., heteroatom doping) to modulate the charge distribution over the carbon network.

Cobalt Covalent Doping in MoS2 to Induce Bifunctionality of Overall Water Splitting

Advances in Materials, 2018
The layer‐structured MoS2 is a typical hydrogen evolution reaction (HER) electrocatalyst but it possesses poor activity for the oxygen evolution reaction (OER).

The new dope on semiconductor doping

Computer, 2004
A University of California, Berkeley, researcher has developed a way to apply semiconductor dopants at the atomic level. Controlling the amount of dopant applied is increasingly important as the size of wires, diodes, transistors, switches, and other semiconductor elements approaches molecular scale.

Gene doping

Essays in Biochemistry, 2008
Gene doping is the misuse of gene therapy to enhance athletic performance. It has recently been recognised as a potential threat and subsequently been prohibited by the World Anti-Doping Agency. Despite concerns with safety and efficacy of gene therapy, the technology is progressing steadily. Many of the genes/proteins which are involved in determining
