Transparent hydrogels are key materials for many applications, such as contact lens, imperceptible soft robotics and invisible wearable devices. Introducing large engineerable optical anisotropy offers great prospect endowing them with extra birefringence-based functions exploiting their applications in see-through flexible polarization optics. However, existing transparent suffer from limitation of low and/or non-fine birefringence. Here, we invent a magneto-birefringence hydrogel finely...

Most current hydrogel actuators suffer from either poor mechanical properties or limited responsiveness. Also, the widely used thermo-responsive poly-(N-isopropylacrylamide) (PNIPAM) homopolymer hydrogels have a slow response rate. Thus, it remains challenge to fabricate with both excellent and responsive properties. Herein, ultrafast VSNPs-P(NIPAM-co-AA) containing multivalent vinyl functionalized silica nanoparticles (VSNPs) are fabricated. The thermo-responsiveness is due mobile polymer...
Abstract High‐level safety is of vital importance to the continuous pursuit high‐energy‐density batteries in increasingly electrified world. The thermal instability and dendrite‐induced issues conventional polypropylene (PP) separators often cause internal short circuits runaway batteries. Herein, a thermally stable dendrite‐resistant separator (F‐PPTA@PP) constructed using dual‐functional easy‐to‐commercialize design strategy safe poly‐p‐phenylene‐terephthamide nanofibers plasma‐induced...
A new electrode consisting of a Ti/PbO2 shell as main (ME) and numerous Fe3O4/Sb-SnO2 granules auxiliary electrodes (AEs) was developed for flexible electrochemical oxidation (EO) treatment wastewater. Material characterizations were carried out to study the impacts loading amount AEs on attribution construction electrode. Lignin, complex group polymeric macromolecules, selected representative actual contaminant test real EO capability assembled with different AE amounts. The stability...
As the amount of PVA microcrystals increases, network structure changes from being dual-crosslinked (for pure PAA hydrogels) to ternary-crosslinked and finally a double structure, as shown by step-increased modulus hydrogels.
Silkworm fibers have attracted widespread attention for their superb glossy texture and promising mechanical performance. The properties can be reinforced with carbon nanofillers, particularly nanotubes (CNTs), depending on the CNT content in silk fibers. In order to increase content, lignosulfonate (LGS) was used as a surfactant ameliorate solubility, dispersibility, biocompatibility. resulting CNT/LGS nano-composite further processed through an additional purification method remove excess...
A model system has been developed to study the redox behaviors of flavin derivatives appended onto random polystyrene copolymers through "click" chemistry strategies. The results demonstrate that units attached polymers exhibit site-isolated behaviors, yielding new materials with electrochemically tunable associations (Ka(ox) = 450 M-1, Ka(red) 18 200 M-1) complementary diamidopyridine (DAP) functionality.
Abstract Developments in self‐assembly methods allow access to hierarchical materials featuring a wide range of functionality and applications. Polymer‐based nanoparticles opens up new avenues for the fabrication highly structured nanocomposites that can serve as bridges between ‘bottom‐up’ ‘top‐down’ methods. Of various interactions leading nanocomposites, hydrogen bonding electrostatic are commonly utilized. In this review, we illustrate design subsequent property tuning self‐assembled...
A hydrothermal synthesis approach was adopted to embed Sb-doped SnO2 into TiO2 nanotubes form a three dimensional electrode(TiO2-NTs/SnO2-Sb), and it compared with the conventionally fabricated Ti/SnO2-Sb2O5 electrode(Sb-doped coated Ti sheet) in terms of surface morphology, crystal structure, photoelectrochemical properties organic degradation performances. It clearly observed from SEM images that TiO2-NTs/SnO2-Sb electrode had compact oxide embedded successfully nanotubes. The loading...
Silicon nitride (SiN) mechanical resonators with high quality properties are attractive for fundamental research and applications. However, it is challenging to maintain these while achieving strong coupling an electrical circuit efficient on-chip integration. Here, we present a SiN drum resonator covered aluminum thin film, enabling large capacitive suspended top-gate. Implementing the full measurement scheme, demonstrate factor ∼104 (comparable that of bare drums at room temperature) our...
Coupled electromechanical resonators that can be independently driven/detected and easily integrated with external circuits are essential for exploring mechanical modes based signal processing multifunctional integration. One of the main challenges lies in controlling energy transfers between distinct experiencing nanoscale displacements. Here, we present a room temperature system mimics "phonon-cavity", analogy optomechanics. It consists silicon nitride membrane capacitively coupled to an...
Specific three-point hydrogen bonding between diamidopyridine (DAP) and thymine (Thy) was employed to reversibly anchor "brush-like" Tri-DAP end-functionalized polystyrene onto Thy-modified silica surfaces.
Abstract Efficient selective extraction of semiconducting single-walled carbon nanotubes (s-SWCNTs) from as-synthesized SWCNTs is essential for their electronic and photovoltaic applications. In this study, we used a relatively simple copolymer backbone structure poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-thiophene] (PFT) the s-SWCNTs HiPCO SWCNTs. The absorption Raman spectroscopies indicated that PFT-sorted had high purity which was far beyond sensitivity spectrometers. Photoluminescence...

Complementary diaminopyridine (DAP) and flavin derivatives self-assemble into discrete helically stacked tetrads in hydrocarbon solvents. The self-assembled structure was demonstrated through induced circular dichroism using DAPs with chiral side-chains achiral side-chains. Flavin were synthesized; cooperativity the self-assembly established (CD) profiles melting curves. It found that placing stereocenters both recognition units resulted a strong bisignated profile enhancement of complex...
