We report the improved performance of all-polymer solar cells with bulk heterojunction nanolayers of an electron-donating polymer (poly(3-hexylthiophene) (P3HT)) and an electron-accepting polymer (poly(9,9-dioctylfluorene-co-benzothiadiazole) (F8BT)), which were both doped with 4-ethylbenzenesulfonic acid (EBSA). To choose the doping ratio of P3HT for all-polymer solar cells, various EBSA dopin...

Doping CeO2 with Pd atoms has been associated with catalytic CO oxidation, but current surface models do not allow CO adsorption. Here, we report a new structure of Pd-doped CeO2(111), in which Pd adopts a square planar configuration instead of the previously assumed octahedral configuration. Oxygen removal from this doped structure is favorable. The resulting defective Pd-doped CeO2 surface is...

We determine the phase diagram of LaFe$_{1-x}$Co$_x$AsO single crystals by using nuclear magnetic resonance (NMR). Up to a nominal doping $x=0.03$, it follows for F-doped polycrystals. Above samples become superconducting, whereas Co-doping structural and transitions can be observed up $x=0.042$, superconductivity occurs only higher levels with reduced transition temperatures. For dopings $x=0....

The exploration of topological electronic phases that result from strong correlations is a frontier in condensed matter physics. One class systems currently emerging as platform for such studies are so-called kagome magnets based on transition metals. Using muon spin-rotation, we explore magnetic the magnet Co$_{3}$Sn$_{2-x}$In$_{x}$S$_{2}$ function In-doping, providing putative evidence an int...

The thermoelectric (TE) performance of pristine Bi2Se3 is inferior to that Bi2Te3. Therefore, the study on has faced a decline. lower due low power factor and high thermal conductivity. In recent years, single aliovalent doping been adopted improve TE Bi2Se3. Here, we adopt an isovalent co-doping approach using indium antimony create manifold enhancement in via creation neutral impurities deep ...

Glycerol is prohibited as an ergogenic aid by the World Anti-Doping Agency (WADA) due to the potential for its plasma expansion properties to have masking effects. However, the scientific basis of the inclusion of Gly as a "masking agent" remains inconclusive. The purpose of this study was to determine the effects of a hyperhydrating supplement containing Gly on doping-relevant blood parameters...
