Water Access, Water Scarcity, and Climate Change [PDF]

open access: yesEnvironmental Management, 2010
This article investigates the approaches of the various discourses operating in the water sector and how they address the issues of scarcity and equitable access under projected climate change impacts. Little synergy exists between the different approaches dealing with these issues.

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

FOOD SECURITY IN A WATER-SCARCE WORLD: MAKING VIRTUAL WATER COMPATIBLE WITH CROP WATER USE AND FOOD TRADE [PDF]

open access: yesScientific Papers Series : Management, Economic Engineering in Agriculture and Rural Development, 2013
Virtual water has been proposed as a mechanism with potential to reduce the effects of water scarcity on food security. To evaluate the role of virtual water in reducing the effect of water scarcity on food security, all components of the available water

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Adapting crop production to water scarcity

open access: yesEnvironmental Research Letters
Rapidly growing global food demand requires increased crop production that is supported by groundwater irrigation in many agricultural regions. This pressure on water sources has led to groundwater depletion already and is likely to increase moving ...

Simultaneous Enhancement of Performance and Stability in Dual‐Gate a‐IGZO Thin‐Film Transistors via Single‐Step Laser Annealing for Capacitor‐Less DRAM

open access: yesAdvanced Functional Materials, EarlyView.
A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Tracking Battery Microstructural Degradation Through Directional Thermal Transport Signatures

open access: yesAdvanced Functional Materials, EarlyView.
In lithium‐ion batteries, heat conduction varies between the through‐plane and in‐plane directions because of the cell's layered structure. Therefore, cell degradation influences thermal conductivity in each direction uniquely due to detailed microstructural and compositional changes.

Modelling the impact of agriculture expansion on water scarcity in Xinjiang, China

open access: yesEcological Indicators
Quantitative evaluation of changes in water supply and demand, water scarcity, and their influencing factors is essential for the sustainable management of regional water resources, food production, and ecological health.
