Review: Groundwater resource potential and status of groundwater resource development in Ethiopia [PDF]
Hydrogeology Journal, 2019 The groundwater resources potential of Ethiopia is estimated to be about 40 billion cubic meters. Groundwater has been used as the main source of water supply since the 1970s for the main cities, towns and dispersed rural communities across the country, where provision of reticulated surface-water schemes is often expensive because of initial project ...

Advanced Functional Materials, EarlyView.An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...

Cemeteries - A Potential Risk to Groundwater
Water Science and Technology, 1991 Cemeteries are a source of environmental impacts among which is featured the risk to groundwater contamination by microorganisms that proliferate during the process of decomposition of bodies. The main objective of this work was to monitor the bacteriological quality of the water from the water table in three cemeteries chosen in accordance with ...

Advanced Materials, EarlyView.A circular upcycling strategy transforms waste poly(ethylene terephthalate) bottles into microwave‐responsive Ni@C catalyst featuring lattice‐distorted nickel cores and defective carbon shells. These strain‐rich heterointerfaces enhance dielectric loss and promote localized microwave hotspots, accelerating peroxymonosulfate activation and polymer‐chain
