Lance Armstrong: it's not about the doping

, 2012
Doping in sport raises issues of justice, liberty and expectations of public figures. This piece explores three areas relevant to this area: should we offer amnesties to those caught doping, should we have more liberal rules, and why (when so many others

Thermally Robust Room‐Temperature Interlayer Excitons in a Hybrid van der Waals Heterostructure

Advanced Functional Materials, EarlyView.
We report an optically active interlayer exciton in a hybrid van der Waals (PEA)2PbBr4/MoS2 heterostructure that remains thermally stable up to 400 K. The emission exhibits polarization anisotropy consistent with an out‐of‐plane optical transition‐dipole component and shows lifetime extension indicative of electron–hole separation.

Simultaneous Reduction of Silver and Indium in Silicon Heterojunction Solar Cells via Contact Transport Engineering

Advanced Functional Materials, EarlyView.
Integrating Ag‐lean Cu@Ag metallization with an In‐lean ITO/SnOX transparent conductive oxide maintains high silicon heterojunction solar cell efficiency with only a slight efficiency penalty while reducing material cost by more than 65%. The study highlights the benefits of jointly optimizing metallization and transparent conductive oxide design to ...
