City boundaries for global urban water scarcity assessment

open access: yesScientific Data
Rapid and continuous urbanization has increased water demand in cities worldwide. Global assessments of urban water scarcity should be conducted using gridded hydrological information, but are hampered by the lack of water-resource-based city boundary ...

A Super‐Adhesive Air Filter With Capillarity‐Mediated Spontaneous Particle Absorption via Dynamic Bond Exchange

open access: yesAdvanced Materials, EarlyView.
We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

open access: yesAdvanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

A study of unsteady flow wave attenuation in partially filled pipe networks

open access: yes, 1984
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.The attenuation of unsteady flow in building drainage systems must be fully considered if water conservation proposals involving changes in flush volume or

Effect of insoluble surfactants on drainage and rupture of a film between drops interacting under a constant force.

open access: yes, 2000
The deformation, drainage, and rupture of an axisymmetrical film between colliding drops in the presence of insoluble surfactants under the influence of van der Waals forces is studied numerically at small capillary and Reynolds numbers and small ...

Building irrigation-tailored soil datasets for land suitability assessment in collective irrigation systems

open access: yesAgricultural Water Management
Reliable soil information is critical for irrigation planning, yet data scarcity and spatial variability often constrain its effective use, particularly in Mediterranean collective irrigation systems (CIS).

Phase Engineering of Nanomaterials (PEN): Evolution, Current Challenges, and Future Opportunities

open access: yesAdvanced Materials, EarlyView.
This review summarizes the synthesis, phase transition, advanced characterization spanning ex situ to in situ and operando techniques, and diverse applications of phase engineering of nanomaterials (PEN). It further outlines key challenges and future opportunities, such as phase stability, architecture control, and artificial intelligence (AI)‐driven ...

Effects of Groundwater Depth on Soil Water and Salinity Dynamics in the Hetao Irrigation District: Insights from Laboratory Experiments and HYDRUS-1D Simulations

open access: yesAgronomy
The management of groundwater depth (GWD) in alluvial soils under irrigation in arid climates is critical for soil and water conservation, given its influence on salt dynamics and water availability for crops.

Méthode analytique généralisée pour le calcul du coning. Nouvelle solution pour calculer le coning de gaz, d'eau et double coning dans les puits verticaux et horizontaux Generalized Analytical Method for Coning Calculation. New Solution to Calculation Both the Gas Coning, Water Coning and Dual Coning for Vertical and Horizontal Wells

open access: yesOil & Gas Science and Technology, 2006
Une nouvelle méthode analytique d'évaluation du coning d'eau par bottom water drive et/ou de gaz par gas-cap drive dans les puits horizontaux et verticaux a été développée pour les réservoirs infinis [1].
