Superior Impact‐Resistant Composite Hydrogels Through an Ionic Coupling Strategy

open access: yesAdvanced Materials, EarlyView.
An ionic coupling strategy is developed to simultaneously reinforce networks and interfaces in composite hydrogels. Sodium citrate acts as a single multifunctional ionic coupler to strengthen the poly(vinyl alcohol) matrix via the Hofmeister effect, reinforce the chitosan–sodium alginate nanofiber network via desolvation and electrostatic crosslinking,

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Efficient Self‐Cleaning and Anti‐Bacterial Behavior Realized by Hierarchical Structure in Hybrid Waterborne Polyurethane Coatings Containing Photocatalyst

open access: yesAdvanced Materials Interfaces, EarlyView.
Hybrid WPU coatings with a hierarchical structure are constructed by first directional freezing polymerization of degradable hydrogels with a vertical channel structure and then filling these channels with aqueous WPU solution containing carbon nitride (g‐C3N4) nanosheets.

Audiencing Artscapes: Encounters between art and audience at Yorkshire Sculpture Park [PDF]

open access: yes, 2011
This thesis explores the ways in which the meanings of site art are inscribed by different audiences and their spatially contingent processes of audiencing. Theoretically and empirically it suggests the importance of the verb ‘audiencing’ over the static

A Comprehensive Review of Waste‐Derived Materials for Solar Still Performance Enhancement

open access: yesAdvanced Materials Interfaces, EarlyView.
Solar desalination reduces energy use and produces freshwater sustainably, but its productivity is limited and cannot meet rising demand. Thus, solar desalination system improvements are sought to boost water productivity. Waste materials are abundantly available and burden the environment, making them low‐cost enhancers for solar desalination systems.

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.
