Advanced Functional Materials, EarlyView.Inspired by skeletal muscles’ precision and endurance, CoilLCE integrates a self‐sensing liquid crystal elastomer/graphene artificial muscle with an embedded Joule‐heating copper coil, enabling closed‐loop multistage actuation with programmable intermediate states (strain accuracy of 2%), and antagonistic coordination (32% total strain). These features

Advanced Functional Materials, EarlyView.Resonant standing waves generate large‐area lattices of liquid‐crystal topological defects that are permanently encoded into polymer coatings by photopolymerization. The preserved director architecture produces thermally reconfigurable surface topographies while maintaining programmable optical functionality, demonstrating a scalable strategy for ...

The Determinants of Bangladesh's Trade: Evidence from the Generalized Gravity Model [PDF]
The application of the generalized gravity model in analyzing the Bangladesh's trade reveals that Bangladesh's trade is positively determined by the size of the economies, per capita GNP differential of the countries involved and openness of the trading ...

Two-Way Models for Gravity [PDF]
The Review of Economics and Statistics, 2017 © 2017 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology. Empirical models for dyadic interactions between n agents often feature agent-specific parameters. Fixed-effect estimators of such models generally have bias of order n-1, which is nonnegligible relative to their standard error.

Advanced Functional Materials, EarlyView.A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)
