A Cu2S/NiOOH Heterojunction Enables Highly Selective Ammonia‐to‐Nitrite Electrooxidation at Industrially Relevant Current Densities

open access: yesAdvanced Materials, EarlyView.
Cu2S/NiOOH heterojunction enables efficient ammonia electrooxidation coupled with hydrogen evolution. Interfacial electronic modulation of Ni sites promotes selective NH3‐to‐NO2− electrooxidation at high current density. In a membrane electrode assembly, Cu2S/NiOOH maintains over 90% Faradaic efficiency of nitrite at 800 mA cm−2, highlighting its ...

Breakthrough Design of Highly Potent Antivirals Against Wild‐Type HIV‐1 and Lenacapavir‐Resistant M66I Variant

open access: yesAngewandte Chemie, EarlyView.
Lenacapavir, the first‐in‐class drug targeting HIV‐1 capsid, is a breakthrough drug in HIV‐1 treatment and prophylaxis. However, a single M66I mutation confers complete viral resistance to lenacapavir. We report herein the design and synthesis of innovative R2 analogs demonstrating low nM potency against HIV‐1 M66I and excellent pharmacokinetics in ...

Disguised as a Sulfate Reducer: Growth of the Deltaproteobacterium Desulfurivibrio alkaliphilus by Sulfide Oxidation with Nitrate

open access: yesmBio, 2017
This study demonstrates that the deltaproteobacterium Desulfurivibrio alkaliphilus can grow chemolithotrophically by coupling sulfide oxidation to the dissimilatory reduction of nitrate and nitrite to ammonium.
