Dynamic Supramolecular Polyurethane Elastomers Enabling Bioinspired Strain‐Adaptive Stiffening to Resolve the Softness–Strength Paradox

open access: yesAdvanced Science, EarlyView.
Segmental‐level molecular engineering of a supramolecular polyurethane elastomer integrates strain‐adaptive chains, soft elastic segments, and dynamic hydrogen bonding motifs. This design reconciles skin‐like softness with muscle‐level strength, offering a sustainable and high‐performance material platform for next‐generation artificial skin and soft ...

The origin principle and the welfare gains from indirect tax harmonization [PDF]

open access: yes, 1996
The purpose of this paper is to establish a parallelism between the analyses in Keen (1987,1989.a) referred to indirect tax harmonization when taxes are levied according to the destination principle and its counterpart when taxes are imposed on an origin

Synergistic Se‐Doping and Accompanying S‐Vacancies Drive Lattice Distortion and p‐Band Modulation for Enhanced Sodium Storage in Sulfides

open access: yesAdvanced Science, EarlyView.
Se‐doping in sulfides facilitates the creation of S vacancies. The collaboration of Se‐doping and S vacancies not only induces lattice distortion to weaken the M─S bonds and lift the p‐band center for improved Na+ adsorption, but also increases the number of charge carriers for an improved electronic conductivity.

Workfare and Trade Unions: Labor Market Repercussions of Welfare Reform [PDF]

open access: yes
Workfare proposals concentrate on the work incentives for welfare recipients, thus focusing on the labor supply side. This paper analyzes the effects workfare has on labor demand when the labor market is unionized.

In Situ Polyurea Integration for Self‐Healing, Durable Transparent Electromagnetic‐Interference Shielding Film

open access: yesAdvanced Science, EarlyView.
A steric‐hindrance molecular engineering strategy uses dimethyl maleate (DMM) to convert poly(1,4‐butanediol) bis(4‐aminobenzoate) (PBDAB) into a precursor with reduced reactivity via Michael addition, thereby retarding the curing process to form a transparent, ultraflexible, and self‐healable secondary‑amine polyurea (PuSA) with a crosslinked network.

Spatially Selective Solvation Chemistry by Local Charge Enrichment for Stable Potassium‐Metal Anodes

open access: yesAdvanced Science, EarlyView.
A MoC/NC functional intermediate medium preferentially interacts with KFSI to reconstruct the interfacial solvation structure and form a KF‐rich inorganic SEI. The synergistic integration of the electronically insulating SEI and MoC/NC suppresses electron tunneling, enables fast and balanced K+/electron transport, and promotes uniform K deposition for ...
