Does China’s Aid in Africa Affect Traditional Donors?
International Studies: Interdisciplinary Political and Cultural Journal, 2019 China’s role as an emerging aid provider and the concept of a social plan in Africa has led to polarised responses in the West. Several say that this “productivist” strategy is much less determined by the concepts of citizenship, legal, social rights ...

Advanced 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 ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization
Advanced Materials Interfaces, EarlyView.Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery
