Summary: In this study, silicone-based lyotropic liquid crystal elastomers with drug-eluting functionality were developed using PDMS and triblock copolymer (DA-F127). Various compositions were explored and evaluated, and three compositions with specific properties of interest were further investigated. The materials demonstrated the ability to encapsulate and release polar and nonpolar substances, with sustained release profiles for up to 6 and 5 days for vancomycin and ibuprofen, respectively. This research presents a lyotropic liquid crystal, silicone-based elastomer with tailorable mechanical properties, water retention capacity, and the ability to host and release active substances.

Summary: Mesoporous materials based on lyotropic liquid crystal templates offer a solution to water scarcity, while polyamide-based thin-film composite membranes have trade-offs between permeability and selectivity. This review explores the advancements in fabricating active layers using liquid crystal templates, analyzes membrane performance, and compares the effects of different substrates on TFC membranes. It also discusses strategies for surface modification and interlayer introduction, and techniques for detecting interfacial structures.

Summary: This study investigates a lyotropic mixture in the calamitic nematic phase and its corresponding calamitic cholesteric phase with the addition of a chiral agent. The structure and local ordering at the nanoscale were analyzed using Small-Angle X-ray Scattering. The results show that the overall shape of the micelles is not modified by the presence of the chiral agent, but the correlation between micelles in the cholesteric phase is increased.

Summary: Dispersing micro- and nanoparticles in liquid crystals is used to tune liquid crystal properties and transfer order onto dispersed particles. Adding ferrofluid droplets to liquid crystals produces a similar system to LC-microparticle dispersions, with added magnetic functionality. The viscosities of various liquid crystalline systems can be measured by moving the ferrofluid inclusions through different types of liquid crystals and determining the effective viscosities as a function of changing environment or other factors.

Summary: Liquid crystals are divided into thermotropic and lyotropic classes, both of which can form nematic phases with preferred orientation. The addition of chiral molecules can induce a chiral nematic phase. Research has shown that the properties of nematic phases can differ significantly between the two classes due to the difference in ordering entities.

Summary: Microfiber fabrication via wet-spinning of lyotropic liquid crystals (LCs) with anisotropic nanomaterials is of great interest due to the excellent physical/chemical properties obtained from the alignment of anisotropic nanomaterials. However, achieving high colloidal stability of anisotropic nanomaterials in lyotropic LCs has been a challenge. In this study, a cationically charged polymeric stabilizer was proposed to effectively adsorb on the surface of boron nitride nanotubes (BNNTs), resulting in high colloidal stability of BNNTs up to 22 wt%. Optical and rheological analysis were used to optimize the phase behavior and rheological properties for wet-spinning of BNNT LCs.

Summary: By studying the optical signals of lyotropic cholesteric liquid crystalline phases under different conditions, it was found that the optical signal of the biaxial cholesteric phase depends on the phases surrounding it when situated between uniaxial cholesteric phases, and must undergo a change if located between uniaxial phases with opposite optical signals.

Summary: In this study, a novel type of D-A non-fused-ring copolymers was designed and synthesized to overcome the trade-off relationship between electrical conductivity and Seebeck coefficient in organic semiconductors. The incorporation of fluorine atoms into the polymer backbone effectively increased the ordered degree of molecular stacking and improved both the electrical conductivity and Seebeck coefficient. The bimodal orientation of polymers played a crucial role in decoupling the correlation between electrical conductivity and Seebeck coefficient.

Summary: This research focuses on the versatile substance, polyaniline/layered double hydroxide (PANI@Nd-Co/LDH), under solvothermal conditions. A thorough analysis of its structure and morphology was conducted using various analytical methods. The findings showed that PANI@Nd-Co/LDH exhibited highly sensitive and specific fluorescence detection of Pb(II) and Al(III), outperforming other heavy metal ions. The sensor demonstrated a turn-off fluorescence response for Pb(II) ions and a turn-on fluorescence response for Al(III) ions. The minimum detectable limits (MDL) were determined to be 9.6 nM for Pb(II) and 220 nM for Al(III). PANI@Nd-Co/LDH could be easily regenerated and reused for multiple cycles. The detection mechanisms involved the inner filter effect (IFE) for Pb(II) and the chelation-enhanced fluorescence (CHEF) effect for Al(III). These results highlight the excellent potential of PANI@Nd-Co/LDH in the detection and recognition of Pb(II) and Al(III) ions.
