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 ...

Labor contracts and flexibility : evidence from a labor market reform in Spain [PDF]
This paper evaluates the effects of a labor market reform in Spain that removed restrictions on fixed-term or temporary contracts. Our empirical results are based on longitudinal firm-level data that covers observations before and after the reform.

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.

Growth, Reform Indicators and Policy Complementarities. [PDF]
In order to assess the growth implications of policy complementarities, this paper applies second-best results to reform indicators. During the transition from central planning to EU integration, which corresponds to a policy cycle, a complementarity ...

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.
