Dual‐Ligand Metal‐Organic Frameworks via In Situ Amidoxime Engineering for Selective Ion Separation

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by microbial ion‐trapping mechanisms, a mild and universal strategy is developed to construct highly porous amidoxime‐functionalized MOFs. DFT calculations and molecular force measurements reveal that the dual‐ligand amidoxime configuration significantly strengthens Ga(III) affinity.

Enhanced Efficiencies for High-Concentration, Multijunction PV Systems by Optimizing Grid Spacing under Nonuniform Illumination

open access: yesInternational Journal of Photoenergy, 2014
The design of a triple junction solar cell’s front contact grid can significantly affect cell conversion efficiency under high concentration. We consider one aspect of grid design, choosing a linear grid within a distributed resistance cell model to ...

Electric Field‐Dependent Conductivity as Probe for Charge Carrier Delocalization and Morphology in Organic Semiconductors

open access: yesAdvanced Functional Materials, EarlyView.
Applying a high electric field to a doped organic semiconductor heats up the charge carrier distribution beyond the lattice temperature, enhancing conductivity. It is shown that the associated effective temperature can be used to extract the effective localization length, which is a characteristic length scale of charge transport and provides ...

Nanolayer‐Encapsulated Stretchable Liquid‐Metal Sheets for Thermal Management

open access: yesAdvanced Functional Materials, EarlyView.
A stretchable liquid metal sheet with both high thermal conductivity and mechanical flexibility is developed. Its trilayer structure, comprising copper‐particle‐dispersed gallium liquid metal encapsulated by styrene‐butadiene‐styrene nanosheets, shows 40.4 W m−1 K−1 conductivity, elongation exceeding 200%, and retention of 96% of its initial ...
