Flexible Supercapacitors Based on Stretchable Conducting Polymer Electrodes.

Supercapacitors are widely used in various fields due to their high power density, fast charging and discharging speeds, and long service life. However, with the increasing demand for flexible electronics, integrated supercapacitors in devices are also facing more challenges, such as extensibility, bending stability, and operability. Despite many reports on stretchable supercapacitors, challenges still exist in their preparation process, which involves multiple steps.

Degradable thiol-acrylate hydrogels as tunable matrices for three-dimensional hepatic culture.

A degradable poly(ethylene glycol)-diacrylate (PEGDA) hydrogel system was developed using simple macromer formulations and visible light initiated thiol-acrylate photopolymerization. In addition to PEGDA, other components in this gelation system include eosin-Y as a photo-sensitizer, bi-functional thiol (dithiothreitol, DTT) as a dual-purpose co-initiator and cross-linker, and N-vinylpyrrolidone (NVP) as a co-monomer. Gelation was achieved through a mixed-mode step-chain growth polymerization mechanism under bright visible light exposure.

Visible light cured thiol-vinyl hydrogels with tunable degradation for 3D cell culture.

We report here a synthetically simple yet highly tunable and diverse visible light mediated thiol-vinyl gelation system for fabricating cell-instructive hydrogels. Gelation was achieved via a mixed-mode step-and-chain-growth photopolymerization using functionalized 4-arm poly(ethylene glycol) as backbone macromer, eosin-Y as photosensitizer, and di-thiol containing molecule as dual purpose co-initiator/cross-linker. N-vinylpyrrolidone (NVP) was used to accelerate gelation kinetics and to adjust the stiffness of the hydrogels.

Polypharmacy among disabled Taiwanese elderly: a longitudinal observational study.

Background And Objective: It is not known whether the correlates of polypharmacy among disabled elderly are similar to those for older adults in general. Furthermore, data on polypharmacy in the Taiwanese population are limited. Therefore, this study was conducted to determine the prevalence and correlates of polypharmacy among disabled Taiwanese elderly (aged >or=65 years).

Characteristics of outpatient prescriptions for frail Taiwanese elders with long-term care needs.

Objective: To describe medication prescription patterns and associated factors among frail Taiwanese elders with long-term care needs defined as having physical or cognitive functioning impairments.

Design: Longitudinal observational study from July 2001 to June 2002.

Setting: Community and Institutions.
