Water Development in South Africa [PDF]
, 2011 A report on South African water development: South Africa's water resources are, in global terms, scarce and extremely limited: average rainfall (450 mm per year) is well below the world average (of about 860 mm), evaporation is comparatively high, no ...

Advanced Science, EarlyView.To tackle low electrocatalytic nitrate reduction to ammonia efficiency in neutral media, this work designs chain‐like dinuclear/trinuclear polyoxometalate‐based metal‐organic complexes. Metal clusters provide nitrate adsorption/activation sites, while polyoxometalates (POMs) drive water dissociation to generate active hydrogen (*H) that migrates to ...

Advanced Science, EarlyView.This study combines the biological structure of octopuses with the “3D structure” of spacer fabrics to fabricate a dual‐interface solar evaporator with adaptive hydrothermal balance. Water adaptation is achieved through the differentiated design of the upper and lower layers, and dynamic hydrothermal balance is realized by dynamically regulating the ...
