Method of manufacturing epoxy compound.
Disclosed is prepn. method of an epoxy compd., characterized by reaction of an olefin with hydrogen peroxide in the presence of a tungsten compd. and a nitrogen-contg. compd. (wherein, pKa of conjugate acid of the nitrogen-contg. comound is 1.5-11.5). For example, to a soln. of tetrahydroindene (THI; 1 mmol) in acetonitrile (5 mL) were added imidazole (

Investigation of the effects of cobalt ions on epoxy properties [PDF]
The effects of Co(acac)sub x complexes on MY-720 epoxy properties have been investigated. It appears that Co2(+) ions form antibonding or nonbonding orbitals which increase the free volume and also reduce the cohesiveness of the host epoxy.

Tunable 3D‐Printed Static Mixers for Gradient Bioprinting With High Cell Viability
ABSTRACT The fabrication of native tissue‐like structures with gradual transitions in material properties, cell types, and growth factors remains a major challenge in biofabrication due to the lack of suitable methods. Mimicking the hierarchical organization of living tissues is essential for functional models, yet creating gradient, multimaterial ...

Molecular Inks for the Development of Complex 3D In‐Mold Electronics
Molecular inks (MINKs) enable the fabrication of thermoformed 3D circuits by decoupling the forming and metallization steps. Following thermoforming, intense pulsed‑light or thermal processing converts the patterned MINKs into complex 3D conductive tracks with improved stretchability and electrical performance, advancing low‑cost, high‑performance in ...

In this study, we report a resistive‐type strain sensor fabricated using single‐walled CNTs, are used layer using the pray technique to deposit as conductive, and UV‐resin was spin‐coated as a protection layer. The sensor functioned in harsh temperature variation conditions from −50°C to 125°C without deterioration.

An Accessible Microfluidic Platform for the Generation of Polarized Brain Organoids
This study presents an accessible double‐gradient microfluidic device that enables controlled morphogen delivery and spatially polarized differentiation in brain organoids. By integrating a pump‐free design and stable fabrication method, the platform generates dorsal–ventral neuronal asymmetry, offering a reproducible and versatile approach to model ...

One‐dimensional C4N2H14PbBr4 is shown to have a quasi‐direct electronic band structure and strongly anisotropic transport with polarized broadband emission. A GW/Bethe–Salpeter excited‐state force formalism, supported by polarized Raman and temperature‐dependent photoluminescence, identifies low–frequency Pb–Br phonons that drive ultrafast exciton self‐
