We demonstrate a polarizer-free electro-optical switch using dye-doped liquid crystal (LC) gels. The mechanism of dye-doped LC gels mainly involves the combination of polymer scattering and dye absorption. However, the domain size of polymer networks, dye concentration, LC concentration, and fabrication process can all affect the phase separation process and thus result in dye-doped LC gels wit...

Properly fabricated polymer gels exhibit an abrupt change in volume in response to a small change in an environmental parameter, such as temperature. We have developed gels that change in volume in response to an applied alternating magnetic field, and we are working to apply these gels as actuators. This paper describes power electronic circuits suitable for electromagnetic activation of these...

Fluorescent supramolecular gel is a large group in luminescent gels. In the scope of practical applications, excellent stability and robust luminescence are complementary indispensable for high-performance fluorescent Therefore, this Perspective, proceedings precursor explorations stabilizing boosting behavior gels will be briefly summarized. The challenges possible development frontiers also p...

BACKGROUND This work aimed to provide useful information on the use of nanoemulsions for the percutaneous administration of triptolide. Lipid nanosystems have great potential for transdermal drug delivery. Nanoemulsions and nanoemulsion gels were prepared to enhance percutaneous permeation. Microstructure and in vitro/in vivo percutaneous delivery characteristics of triptolide (TPL)-nanoemulsio...

In this study, a novel composite gel was fabricated from Konjac glucomannan (KGM) combined with zein, while its properties and structure were characterized. The effect of the KGM/zein ratios freeze-thaw treatment on gels investigated. storage modulus (G?) KGM increased even when zein content below 20%, partial phase separation occurred exceeded 50%. initial decomposition temperature improved by...

The effects of dermal fibroblasts on keratinocyte outgrowth on collagen substrata was studied using an in vitro keratinocyte-collagen gel composite model. Skin fibroblasts were seeded inside collagen gels, which remained attached to the cell culture plastic substratum. Fibroblasts incorporated in collagen gels were either kept viable throughout the study, or were lysed hypotonically with water ...

Polymer gels that exhibit a change in volume in response to a small change in an environmental parameter such as temperature have been fabricated and studied for several decades. We have developed gels that change volume in response to an applied alternating magnetic field. These gels could serve as actuators in servomechanisms. This paper presents practical techniques for using closed-loop fee...

Intelligent ion gels, which possess highly tunable mechanical, electrical, and stimulus-responsive properties, have emerged as powerful candidates in the field of artificial intelligence, telemedicine, health monitoring. To enrich functionality it is critical to explore link between structure function gels. In this review, we provide an overview synthesis path functional derivatives The conform...
