U.S. planetary exploration program
Eos, Transactions American Geophysical Union, 1979 Geoffrey A. Briggs, who is the Deputy Director of NASA's Planetary Division, Office of Space Science, recently described in a ‘Dear Colleague’ letter what he considers is a less bright future for U.S. planetary exploration. This disheartening view may come as news to many scientists who are aware of the enormous achievements of the space program in ...

Advanced Science, EarlyView.The formation of insulating Li2S during discharge in solid‐state lithium–sulfur batteries passivate reaction sites and limits sulfur utilization. In this work, a microstructure‐resolved modeling framework coupling transport and reaction kinetics is developed to predict charge–discharge behavior and reveal particle‐scale species evolution and incomplete

Advanced Science, EarlyView.Photocatalytic treatment of glyphosate herbicide in agricultural wastewater is achieved through the cooperative effect of the local polarization field and dipole field mediated by lattice‐distorted carbon nitride. Glyphosate is completely degraded via selective C─P bond cleavage with a CO evolution rate of 1166 µmol g−1 h−1.
