The critical role that dopants play in semiconductor devices has stimulated research on the properties and the potential applications of semiconductor nanocrystals, or colloidal quantum dots, doped with intentional impurities. We review advances in the chemical synthesis of doped nanocrystals, in the theoretical understanding of the fundamental ...

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, 2018Carbon 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.

International Journal of Sports Medicine, 2006
Together with the rapidly increasing knowledge on genetic therapies as a promising new branch of regular medicine, the issue has arisen whether these techniques might be abused in the field of sports. Previous experiences have shown that drugs that are still in the experimental phases of research may find their way into the athletic world.

Journal of Vacuum Science and Technology, 1979
The MBE technique has made feasible the growth of periodic semiconductor structures composed of ultrathin layers with alternating p- and n-doping. This kind of superlattice, in contrast to familiar heterostructure systems, does not contain any interfaces, and, therefore, does not show the problems related to those. Doping superlattices, on the contrary,

Abstract Doping CeO2 cubic fluorite with transitional metal ions can effectively improve its redox behavior, oxygen storage capacity and catalytic performance, but the relevant fundamental understanding of the promotion effect is still insufficient due to the difficulty on determining the distribution of dopant.

Abstract Doping in sport, with its connotations of unethical behaviour and harm to health, has existed since antiquity. In contemporary times, an acceleration of doping practices resulted in the eventual development of a robust legal and scientific framework now entrenched in the World Anti-Doping Code.

Gene doping abuses the legitimate approach of gene therapy. While gene therapy aims to correct genetic disorders by introducing a foreign gene to replace an existing faulty one or by manipulating existing gene(s) to achieve a therapeutic benefit, gene doping employs the same concepts to bestow performance advantages on athletes over their competitors ...
