Self‐Healing Pd(II) Cage Metallogels for Iodine Capture in Water and Heterogeneous Photocatalysis

Advanced Science, EarlyView.
Two carbazole‐derived metal‐organic cages hierarchically self‐assemble into supramolecular metallogels that integrate autonomous self‐healing, reversible stimuli responsiveness, high‐capacity aqueous iodine capture, and visible‐light‐driven photocatalytic sulfide oxidation within a single multifunctional platform.

Trade-offs between water-saving and aquifer recharge: evaluating canal lining strategies in the Nile Delta

Water Science
Efficient management of irrigation water is critical for sustaining agriculture in the Nile Delta, where canal seepage serves as both a loss from surface water delivery and a key recharge mechanism for the shallow aquifer. This study assessed the impacts

A review: research methods that describe the environmental behavior of colloids in groundwater

Shui kexue jinzhan, 2016
Colloids are widely distributed in groundwater systems and facilitate transport of trace elements and organics. They therefore play an important role in mass transfer with subsequent impacts on groundwater quality. In this contribution,we have summarized

Effect of Hydrate on Gas/Water Relative Permeability of Hydrate-Bearing Sediments: Pore-Scale Microsimulation by the Lattice Boltzmann Method

Geofluids, 2021
As a clean energy source with ample reserves, natural gas hydrate is studied extensively. However, the existing hydrate production from hydrate deposits faces many challenges, especially the uncertain mechanism of complex multiphase seepage in the ...

Groundwater flood or groundwater-induced flood? [PDF]

Quarterly Journal of Engineering Geology and Hydrogeology, 2012
A number of ‘groundwater flood’ events have been recorded over the Chalk aquifer in southern England since the 1994 occurrence at Chichester, Sussex. Reporting of this event and subsequent groundwater floods indicates that there are two types of groundwater flood event. Type 1 is the true groundwater flood in which the water table elevation rises above

Interfacial Salt Redistribution Enables Rapid Atmospheric Water Harvesting in a Biomimetic Multi‐Layer Hygroscopic Membrane

Advanced Science, EarlyView.
A biomimetic multi‐layer hygroscopic membrane redistributes salt toward an air‐accessible nanofiber interface, enabling rapid interfacial deliquescence while a brush‐like hydrogel promotes efficient liquid transport and storage. By decoupling vapor capture from bulk water storage, the membrane achieves fast sorption kinetics and enables rapid‐cycling ...

Climate Change is Rewriting the Hydroclimatic Operating Envelope of Mines

Advanced Science, EarlyView.
Climate change is shown to shift the hydroclimatic operating envelope of mines: 16.2% of represented mine locations have already changed Köppen subtype, rising to 42.5% by late century under SSP5‐8.5. Divergent water trajectories are filtered through geology, infrastructure and lifecycle stage, indicating that adaptation requires monitored, scenario ...

Paleo-modeling of coastal saltwater intrusion during the Holocene: an application to the Netherlands [PDF]

Hydrology and Earth System Sciences, 2014
Coastal groundwater reserves often reflect a complex evolution of marine transgressions and regressions, and are only rarely in equilibrium with current boundary conditions.

Groundwater dependent ecosystems – groundwater status indicators

Natura Sloveniae, 2016
Within the framework of »Water Management Plan for the Danube River Basin and the Adriatic Sea 2015-2021 (NUV II)«, a study on the groundwater status of karst aquifers which are habitats of groundwater dependent ecosystems (GDEs) was carried out. Among them are the habitats of olms (Proteus anguinus), the endemic species of Dinaric karst.

Toward Sustainable Separation and Recovery of Critical Metals From Discarded Industrial Perovskite Solar Modules

Advanced Science, EarlyView.
An architecture‐guided recycling process enables selective metal recovery from end‐of‐life perovskite solar modules by exploiting interfacial accessibility and calcination‐induced phase transformation. The process achieves >99.8% Pb removal, >99.7% In recovery, and >96.1% Cu recovery, while selectively retaining Sn in leaching residue.
