Hierarchically MOF‐Based Porous Monolith Composites for Atmospheric Water Harvesting
Advanced Materials, EarlyView.This review explores the design of hierarchical porous materials for atmospheric water harvesting, focusing on metal‐organic frameworks (MOFs) and porous monoliths. Emphasis is placed on integrating MOF nanoscale porosity with the microscale channels of monolithic scaffolds to enhance sorption‐desorption performance.

Groundwater dependence and drought within the southern African development community [PDF]
, 2005 A groundwater situation analysis of the SADC region has been undertaken as part of the World Bank GEF Programme as a basis for ensuring equitable use of groundwater resources, particularly during periods of drought, both for human needs and for ...

CO2‐Responsive Smart Wood Scaffold for Natural Organic Matter Removal without Secondary Pollution
Advanced Materials, EarlyView.A CO2‐responsive smart wood scaffold is developed for sustainable water purification, achieving efficient natural organic matter (NOM) removal and microbial disinfection without secondary pollution. The CO2‐responsive polymer coating undergoes protonation upon CO2 exposure, enabling strong cation−π interactions with NOM.

Prospective of groundwater overexploitation through participatory approaches: Saiss plain in Morocco [PDF]
, 2015 In the Saiss plain, groundwater overexploitation is often explained by two phenomena. The first one is a natural phenomenon (droughts), which seems therefore uncontrollable; the other one is human as groundwater is largely used by the agricultural sector.

Quantification of nitrate removal by a flooded alluvial zone in the Ill floodplain (Eastern France) [PDF]
, 1999 The nitrate reducing capacity of a flooded system in the Ill floodplain (Eastern France) was investigated for a period of 2 years. The methodology used consisted of a spatio-temporal monitoring of stream flow and nitrate concentrations in the groundwater

Advanced Materials, EarlyView.This work constructs asymmetric Sn‐Cu‐C interface via anchoring SnCu atomic clusters on carbon defects. Such as‐synthesized SnCu‐DG catalyst achieves a high NH3 Faradaic efficiency (99.5%) and a record intrinsic activity of 2.61 × 10−17 mmol h−1 siteCu−1 at neutral electrolyte condition.

Evaluation of the performance of a hydraulic barrier by the Null space Monte Carlo method
Acque Sotterranee, 2019 A gasoline leak caused the contamination of a shallow alluvial aquifer in an urbanized area in Northern Italy. A rapid intervention was conceived to stop the spreading of contamination: a hydraulic barrier has been placed downstream of the source to ...
