Toward Flexible Printed Electronics: A Spider‐Silk‐Inspired, Strong and Tough Thermoplastic Polyamide Elastomer

Advanced Science, EarlyView.
Inspired by spider silk, a bio‐inspired polyamide elastomer with a dynamic physical cross‐linking network is developed. Mimicking the rigid β‐sheet crystals and sacrificial hydrogen bonds of silk, the material achieves an exceptional balance of strength and toughness.

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

Advanced 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.

Depth‐of‐Discharge‐Dependent Chemical Evolution in Sulfurized Polyacrylonitrile Cathodes for Ether‐Based Room‐Temperature Sodium–Sulfur Batteries

Advanced Energy Materials, EarlyView.
Sulfurized polyacrylonitrile (SPAN) is investigated as a cathode for room‐temperature Na–S batteries in ether‐based electrolytes under controlled discharge depths. Depth‐of‐discharge‐dependent structural evolution reveals that deep discharge below 1.0 V destabilizes SPAN structure, alters polysulfide equilibria, and promotes sodium dendrite formation ...

Analyzing individual rent price ratios in eastern German agricultural land markets: A GAMLSS approach

Agribusiness, EarlyView.
Abstract This study explores the rent price ratio in agricultural land markets, crucial for evaluating market efficiency, policy needs, and farmer decision‐making. Traditionally, the analyses faced challenges due to the absence of concurrent sale and rent data for the same land, potentially leading to biased results.

Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

American Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market
