Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

High Thermoelectric Performance in Low‐Cost Cu8SiSxSe6‐x Argyrodite

open access: yesAdvanced Functional Materials, EarlyView.
This study discovers the great potential of Cu8SiSxSe6‐x argyrodites as new, low‐cost, Te‐free thermoelectric materials. The proposed defect scheme suppresses the phase transition, enhances the weighted mobility and optimizes the grain boundary contacts.

Association between solid fuel use and cognitive impairment: A cross-sectional and follow-up study in a middle-aged and older Chinese population

open access: yesEnvironment International, 2021
Background: To date, few studies have focused on the influence of indoor air pollution on cognitive impairment. Thus, we aimed to explore the association of household fuel use, the major cause of household air pollution, with cognitive functioning among ...

Coupling Interfacial Redox‐Reactions with In Situ Proton Generation for the Photoelectrochemical Separation of Rare‐Earth Elements

open access: yesAdvanced Functional Materials, EarlyView.
To enhance the sustainability of electrochemical separations for resource recovery, a photoelectrochemical ion recovery system is developed that utilizes renewable solar energy. A composite integrating titianium dioxide nanorods and a redox‐copolymer enables spontaneous cation adsorption and light‐activated redox reactions for regeneration, thus ...

Transient Stiffness Patterning in Hydrogels Driven by Dissipative Mechanochemical Coupling

open access: yesAdvanced Functional Materials, EarlyView.
Force‐induced disulfide bond rupture in a polymer‐based hydrogel, coupled with chemical or electrochemical reoxidation, leads to the transient modulation of the hydrogel's stiffness properties. High spatiotemporal control is achieved by this dissipative process, enabling the development of out‐of‐equilibrium stiffness patterns and transient, dose ...
