A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...

A Strong and Water‐Retaining Biomass Adhesive Inspired by Tofu
Drawing inspiration from the formation mechanism of the traditional food tofu, a strong and water‐retaining adhesive is designed using the soybean meal (SM) oxidized by glucose oxidase (GOx) and calcium sulfate oligomer (CSO). This design strategy effectively addresses the conflicting requirements of water‐resistant bonding strength and water retention

High‐Resolution Patterned Delivery of Chemical Signals From 3D‐Printed Picoliter Droplet Networks
3D‐printed picoliter droplet networks have been fabricated that control gene expression in bacterial populations by releasing chemical signals with precise spatial definition and high temporal resolution. This system of effector release is widely applicable, offering diverse applications in biology and medicine.

The SciAgents AI model drives hypothesis generation by harnessing multi‐agent graph reasoning, extracting insights from knowledge graphs constructed from scientific papers. Each agent plays a specific role: the Ontologist defines concepts, the Scientists draft and refine proposals, and the Critic reviews.

High‐Performance Recyclable Polyester Elastomers Through Transient Strain‐Stiffening
Transient strain‐crystallization simultaneously strengthens and toughens block polyester elastomers while conserving recyclability. Using controlled polymerization catalysis and commercial monomers, block polyester elastomers outperform current commercial elastomers, entering a new region of tensile mechanical property space.

Efficient Synthesis of Amino Lactones via Copper‐catalysed Alkene Aminooxygenation
Abstract The synthesis of 5–7 membered oxygenated heterocycles by intramolecular aminooxygenation of unsaturated alkenes using commercially available N‐fluorobenzenesulfonimide as amination reagent and TpiPr2Cu(NCCH3) as precatalyst is reported. With unsaturated aliphatic carboxylic acids, the corresponding lactones are obtained from moderate to almost

A straightforward synthesis of spirolactones from carbonyls via N‐tosylhydrazones is described. The process consist in the reaction between the N‐tosylhydrazone and ethoxycarbonylethylboronic acid or ethoxycarbonylpropylboronic acid, leading to spiro γ‐butyrolactones or δ‐valerolactones respectively. The transformation takes place by carboborylation of
