Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration

open access: yesAdvanced Functional Materials, EarlyView.
Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

open access: yesAdvanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Does Financial Openness Promote Economic Integration? [PDF]

open access: yes
The effect of financial openness on economic integration for two clusters of countries is estimated: the formerly planned economies of Eastern Europe and central Asia (emerging market economies) and some western advanced economies.

Quasi‐Static to Supersonic Energy Absorption of Nanoarchitected Tubulanes and Schwarzites

open access: yesAdvanced Functional Materials, EarlyView.
Nanoarchitected energy‐absorptive Tubulanes exhibit record energy absorption under quasi‐static conditions and exceptional inelastic energy dissipation under 750 m s−1 ballistics impact, with high performance spanning strain rates of 12 orders of magnitude.

Trade and Growth in East Asian Countries: Cause and Effect? [PDF]

open access: yes
Estimates of growth equations have found a role for openness, particularly in explaining rapid growth among East Asian countries. But major concerns of simultaneous causality between growth and trade have been expressed.

Regiorandom Polythiophenes for Fully Stretchable Electrochemical Transistors and Logic Circuits

open access: yesAdvanced Functional Materials, EarlyView.
Regiorandom (RRa) polythiophenes, once regarded as unsuitable for electronics, exhibit exceptional switching performance via volumetric electrochemical doping. Optimized RRa‐based organic electrochemical transistors (OECTs) achieve a high on/off ratio (≈104), stable operation under 200% strain, and enable fully stretchable logic gates, demonstrating ...

A note on the determinants of inflation starts in the OECD [PDF]

open access: yes
Boschen and Weise (Journal of Money, Credit and Banking, (2003)) model the probability of a large upturn in inflation. We extend their work to show that openness to trade exerts a negative effect on the probability of such an event.Inflation starts ...
