Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents

open access: yesPolymer International, EarlyView.
The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐

Degradation of Crystalline Si‐Based Solar Modules With Varying Material Combinations—Part I: Encapsulant Degradation

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
This work deals with the degradation of solar modules with varying material combinations under accelerated aging conditions. By in situ moisture measurements and simulations of oxygen ingress, the consumption of stabilizing additives and polymer degradation can be correlated spatially resolved with the penetrating stressors.

Kirigami‐Inspired Deployable Microneedle Robot With Enhanced Conformability for Targeted Oral Drug Delivery

open access: yesSmall, EarlyView.
We have engineered a kirigami‐inspired deployable microneedle robot (KiriBot) capable of remotely controlled attachment to target tissues for sustained drug release. KiriBot incorporates a flexible structure that enhances conformability, improves adherence to irregular tissues, and facilitates microneedle insertion.
