Anode-free all-solid-state lithium metal batteries (ASLMBs) promise high energy density and safety but suffer from a low initial Coulombic efficiency rapid capacity decay, especially at cathode loadings. Using operando techniques, we concluded these issues were related to interfacial contact loss during stripping. To address this, introduce conductive carbon felt elastic layer that self-adjusts the pressure anode side, ensuring consistent lithium–solid electrolyte contact. This...
Aptamers as new modes of detection have strong affinity and specificity for targets. A novel sensor was developed by constructing a composite system specific aptamers reduced graphene oxide (rGO)/graphitic carbon nitride (g-C3N4) (GCN) detecting the cadmium cation. Attributed to incorporation rGO with designed terminal groups well delicate bonding g-C3N4, this electrochemical biosensor exhibited good sensitivity, specificity, reproducibility, stability Cd2+ detection. The linear calibration...
Abstract A hyperelasticity modelling approach is employed for capturing various and complex mechanical behaviours exhibited by macroscopically isotropic polydomain liquid crystal elastomers (LCEs). These include the highly non-linear behaviour of nematic-genesis LCEs, soft elasticity plateau in isotropic-genesis under finite multimodal deformations (uniaxial pure shear) using in-house synthesised acrylate-based LCE samples. Examples application to continuous softening (i.e., primary loading...
Abstract The increasing demand for wearable electronics calls advanced energy storage solutions that integrate high electrochemical performances and mechanical robustness. Ionogel is a promising candidate due to its stretchability combined with ionic conductivity. However, simultaneously optimizing both the performance of ionogels remains challenge. This paper reports tough highly ion‐conductive ionogel through ion impregnation solvent exchange. fabricated consists double interpenetrating...
Methylammonium lead iodide (CH3NH3PbI3), with the organic-inorganic hybrid perovskite (OIHP) structure, has gained tremendous research interest due to its excellent photo-electron conversion ability in application of photovoltaics. Despite solution processed polycrystalline thin film form solar cells, single crystalline counterpart may offer some incredibly novel optoelectronic functionalities. In this work, a sizable (>5 mm) and high quality CH3NH3PbI3 crystal been synthesized by inverse...
Abstract Liquid crystal elastomers (LCEs) are made of liquid molecules integrated with rubber-like polymer networks. An LCE exhibits both the thermotropic property crystals and large deformation elastomers. It can be monodomain or polydomain in nematic phase transforms to an isotropic at elevated temperature. These features have enabled various new applications LCEs robotics other fields. However, despite substantial research development recent years, thermomechanical coupling remains poorly...
Due to the disruption of liquid-crystal order caused by photoisomerization rodlike molecules, solids containing light-sensitive molecules such as nematic elastomers can undergo large reversible shape changes when stimulated light. In this paper, we study surface deformation illuminated light based on a phenomenological model. Numerical computation shows that topography depends remarkably spot radius The result is expected helpful practical applications related creation patterns, guidance...
Photoactive liquid crystal elastomers are polymer networks of mesogens embedded with chromophores like azobenzene. They undergo large deformation when illuminated by light a certain wavelength through photochemical reaction, inspiring exciting new applications. However, despite the recent progresses in both experiment and theory these materials, fundamental understanding temperature effect on their photomechanical actuation various molecular-to-mesoscale processes have remained largely...
