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...

Molecular imprinting finds relevance and importance in a range of applications including the development of new chemical sensors, separation technologies, and selective binding particularly for catalytic and bioreactors. While molecular imprinting technology has found success when imprinting small molecules, progress in molecular imprinting of biomacromolecules, such as polypeptides and protein...

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 ...

An algorithm for determining correspondences between images has been developed and applied to the analysis of 2-D Electrophoretic gels[2, 6]. Various heuristics both derived from the comparison problem and the specific application are incorporated into the algorithm and result in a fairly high level of accuracy. Consistency checking mechanisms, based on exploring violations of a basic symmetry ...
