Hierarchically Wrinkled Silver Ink as a Platform for Fully Integrated Stretchable Electronic Systems
Silver Hierarchical Responsive ink (SHRink), a universal approach for the fabrication of highly stretchable interconnects, wirings, and skin‐interfaced electrodes, is realized through low‐cost, scalable spray‐printing and transfer‐printing. The SHRink demonstrates high electrical conductivity (1.2E04 S cm−1) and large stretchability (235% max fracture ...

Star-branched polystyrenes by nitroxide living free-radical polymerization
Star-branched polystyrenes, with polydispersity indices of 1.15-1.56 and 4-644 equal arms, were synthesized by the reaction of 2,2,6,6-tetramethylpiperidin-1-yloxy (TEMPO)-capped polystyrene (PS-T) with divinylbenzene (DVB).

Cellulose fibers functionalized using cationic poly(Dimethyldiallylammonium chloride) (polyDADMAC) and laccase‐mediated ferulic acid system are processed into foams using different surfactants (Anionic, cationic, and non‐ionic). Fiber–surfactant interactions influence foam stabilization and porous structure formation during convective drying, producing

Thermal degradation of alkyne-containing polystyrenes
The synthesis and thermal behavior of several alkyne-containing polystyrenes was studied. The introduction of the alkynyl group was performed by coupling reaction of poly(p-bromostyrene) with alkynes using palladium/copper catalyst.

Programming Actuation in 3D‐Printed Micro‐Architectures via Interfacial Adhesion Control
A two‐phase meniscus‐guided 3D printing method directly fabricates microscale poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and poly(vinyl alcohol) (PVA) bilayers with in situ programmable interfaces. Modulating the meniscus stretching speed switches the interface between separated and bonded states, which controls the mechanical ...

Bridging rigid electrodes with soft, irregular tissues demands more than conductivity alone. Modular conductive hydrogels autonomously reconfigure into conformal electrode‐tissue interfaces, coupling mixed ionic‐electronic conduction with tissue‐like mechanics, self‐healing, and degradability.

Hydrophilic nanoporous polystyrenes and 1,2-polybutadienes
Nanoporous polymers from ordered block copolymers having hydrophilic cavity surfaces were successfully prepared by two methodologies: ' 1. Nanoporous polystyrenes fromPtBA-b-PS diblock or PDMS-b-PtBA-b-PS triblock copolymer precursors by atom transfer ...

Self‐Sealing Microneedles Improve Precision and Reduce Reflux in Subretinal Cell Transplantation
Ultrafine 49G microneedles enable subretinal delivery of induced pluripotent stem cell‐derived retinal pigment epithelial cells through a 50 µm outer diameter tip. Compared with conventional 38G microcannulas, these microneedles reduce cell suspension reflux in a rabbit model, highlighting the potential of microinvasive delivery instruments to improve ...

We have used the pulsed-gradient spin-echo method to measure the self-diffusion of linear and three-armed star-branched polystyrenes and polybutadienes (3 × 103 M 106) dissolved in CC14 at 50 °C.
