Abstract:
In a study published in Advanced Materials, the researchers from Hefei National Laboratory for Physical Sciences at the Microscale, the University of Science and Technology of China of the Chinese Academy of Sciences, using an electron-proton co-doping strategy, invented a new metal-like semiconductor material with excellent plasmonic resonance performance. This material achieves a metal-like ultrahigh free-carrier concentration that leads to strong and tunable plasmonic field.

Plasmonic materials are widely used in the fields including microscopy, sensing, optical computing and photovoltaics. Most common plasmonic materials are gold and silver. Some other materials also show metal-like optical properties but just perform poor in limited wavelength ranges.

Abstract:
Ribosomes are the complexes of ribonucleoproteins at the heart of protein synthesis in cells. However in the absence of conclusive evidence, how these complexes operate has been open to debate. Now Hirotatsu Imai and Noriyuki Kodera at Kanazawa University, alongside Toshio Uchiumi at Niigata University in Japan, show visualizations of the structural dynamics and factor pooling that take place at ribosome stalk proteins as they build new proteins.
