Abstract Electrically‐induced oblique helicoidal cholesterics (Ch OH ) are attractive for use in reflective displays due to tunable photonic band gap (PBG) a broad spectral range and natural eye‐friendly feature. However, the lack of stable liquid crystal (LC) material system with wide temperature unknown driver architecture hinder implementation Ch ‐based displays. Here, prototype full‐color display device based on electrically‐tunable ‐LC is demonstrated. In comparison ‐S1, S2 S3 samples,...
Abstract The burgeoning growth in electric vehicles and portable energy storage systems necessitates advances the density cost‐effectiveness of lithium‐ion batteries (LIBs), areas where lithium‐rich manganese‐based oxide (LLO) materials naturally stand out. Despite their inherent advantages, these encounter significant practical hurdles, including low initial Coulombic efficiency (ICE), diminished cycle/rate performance, voltage fading during cycling, hindering widespread adoption. In...
Cyclic voltammetry (CV) and electrochemical impedance spectroscopies (EIS) of 2M V (IV) electrolyte in CH3SO3H H2SO4 mixed acid solution (MAS sample) (Pristine as the positive vanadium redox flow battery (VRFB) were investigated. CV results revealed that MAS sample had a higher reversible reaction than Prisinte sample. EIS showed that. The performance VRFB with was investigated charge-discharge technique. At 120 mA/cm2, exhibited energy density (39.87 Wh/L) comparison Pristine Cycling tests...
A series of side-chain polysiloxane liquid crystalline elastomers, E-Cm (where m is the number carbon atoms in interim alkyl groups, and = 4, 6, 8, 10), with binaphthalene derivatives as crosslinkings, were designed synthesized. The mesophase structures these elastomers dependent on value m. ≤ 8 could form cholesteric (Ch) phases, while both smectic Ch phases be formed for elastomer 10. Blue can achieved when ≥ 8. Besides, helical twisting power (HTP) all exhibits a turning point changing...
Abstract The broadband polarising films with pitch gradients induced by the diffusion of nematic liquid crystal (N-LC) monomer in chiral crystals (N*-LCs) during photopolymerisation process have been studied theoretically and experimentally. It was found that bandwidth such broadened sharply after polymerisation. To elucidate mechanism photoinduced gradients, fractured surface morphology polymer network sample were observed scanning electron microscopy (SEM). influence dye concentration,...
The arrangement of the title compound (crystal <bold>I</bold>) was regulated <italic>via</italic> different solvates and cocrystals (crystals <bold>II–V</bold>) for fluorescence modulation.
Cholesteric liquid crystals (CLCs) have recently sparked an enormous amount of interest in the development soft matter materials due to their unique ability self-organize into a helical supra-molecular architecture and excellent selective reflection light based on Bragg relationship. Nowadays, by virtue building self-organized nanostructures with pitch gradient or non-uniform distribution, extensive work has already been performed obtain CLC films broad band. Based authors' many years'...
A charge transfer organic cocrystal 1 was constructed from an anthracene derivative, 1-(5-(anthracen-9-yl)-3-(4-methoxyphen-yl)-4,5-dihydropyrazol-1-yl)ethanone (AMPE) and TCNQ. Eight solvates which can be placed into types I II were obtained solution. Type include 1·toluene, 1·chlorobenzene, 1·o-chlorotoluene, 1·p-chlorotoluene, 1·o-xylene, 1·m-xylene, 1·p-xylene-1, while 1·p-xylene-2 belongs to type solvate. Crystal structure analysis revealed that isomorphic desolvate of solvates....

An enhanced mechanical and thermal property phase change composite was successfully prepared. A paraffin is absorbed by expanded graphite confined polyethylene, Ethylene-propylene terpolymer added cross-linked to polyethylene improve properties. Melting temperature latent heat of the are 41.5 °C 143.8 J g–1, respectively.

A bandwidth-controllable reflective gel has been investigated from photo- and thermally-induced processes. Due to the pitch of cholesteric liquid crystal (CLC) composite increasing as temperature rises, CLC with short is frozen by UV-curing polymer network at low long fixed heat curing high temperature. non-uniform distribution CLCs forms in when becomes low. It demonstrated that memory effect an important mechanism for resulting gel.
In this study, we demonstrate a new method for obtaining binary chiral mixture (BCM) which exhibits an unprecedented temperature-dependent helical twisting power (HTP) by utilising the conflict between two dopants with opposite handedness and HTP temperature dependence. Different from common dopant reported before, addition of such BCM could increase clearing host liquid crystal (LC). Due to sufficiently large value BCM, three primary colours (blue, green red) can be easily reflected nematic...
