Single- or few-layered h-BN nanosheets (BNNSs) are analogous to graphene and possess unique properties. However, their technological applications were severely hindered by the low production efficiency of BNNSs. We reported here a study in which BNNSs efficiently produced exfoliating bulk powder thionyl chloride without using any dispersion agents. The yield was as high 20%, it could be doubled through second round exfoliation precipitate. Microscopic results revealed that generally...
Fiber-based sensors are desirable to provide an immersive experience for users in the human–computer interface. We report a hierarchically porous silver nanowire-bacterial cellulose fiber that can be utilized sensitive detection of both pressure and proximity human fingers. The conductive was synthesized via continuous wet-spinning at speed 20 m/min, with diameter 53 μm, electrical conductivity 1.3 × 104 S/cm, tensile strength 198 MPa, elongation strain 3.0% break. fibers were coaxially...
We demonstrate a single-phase, two-way shape actuator that, in the absence of an external load, elongates upon cooling and reversibly contracts heating. In simple straightforward process, partially cross-linked, semicrystalline poly(ε-caprolactone) (PCL) network is melted, stretched to several hundred percent strain, further cross-linked. Upon removal applied elastic double adopts "state-of-ease" that retains part its former strain. When cooled, internal stress-induced crystallization causes...
NH4+ preintercalated V2O5·nH2O nanobelts with a large interlayer distance of 10.9 Å were prepared by the hydrothermal method. The material showed specific capacity 391 mA·h·g-1 at 500 mA·g-1 current density in aqueous rechargeable zinc batteries. In operando synchrotron X-ray diffraction demonstrated that experienced reversible solid-solution reaction and two-phase transition during charge-discharge cycling, accompanied formation/decomposition ZnSO4Zn3(OH)6·5H2O byproduct. absorption...
Abstract Paper has remained the world's most‐widely accessible information medium even as sustainable and reusable paper replacements have attracted increasing attention. Here, an ink‐free rewritable concept is developed that combines recent developments in photonic crystals, shape memory polymers, electroactive polymers a nanocomposite matches benefits of zero‐energy, long‐term data storage medium, but provides additional advantage rewritability. The consists ferroferric oxide‐carbon (Fe 3...
Dielectric elastomer actuators (DEAs) feature large, reversible in-plane deformation, and stacked DEA layers are used to produce large strokes in the thickness dimension. We introduce an electrophoretic process concentrate boron nitride nanosheet dispersion a dielectric precursor solution onto designated electrode surface. The resulting unimorph nanocomposite (UNDE) has seamless bilayer structure with 13 times of modulus difference. UNDE can be actuated bending curvatures, enhanced breakdown...
Abstract Zinc‐ion batteries (ZIBs) that use water‐based electrolytes have attracted significant attention. However, under harsh conditions, extreme heat is accumulated inside ZIBs, which inevitably causes thermal runway risk. Therefore, the practical applications of rechargeable ZIBs are significantly limited because internal by conditions induces drastic bulges or even explosions. To overcome this limitation, a self‐adaptive thermoregulatory hydrogel electrolyte (TRHE) integrates phase...
An aqueous supercapacitor is an emerging energy storage unit on account of its low cost, fast delivery rate, and long service life. The density can be enlarged via extending the voltage window electrode materials, while electrolyte remains thermodynamically constant at 1.23 V. Herein, with a 2.0 V high-voltage realized by core-shell MoO3-x/polypyrrole (MP) nanocomposites as both cathode anode materials. ultrathin PPy layer MoO3 core not only improves conductivity cycle stability but also...
Controlling network architecture and chain connectivity is critical to understanding elastic energy storage improving performance of shape-memory polymers. Acrylate-terminated poly(caprolactones) were converted into thermoset networks by three different reactions: conventional free radical polymerization, radical-induced coupling with multifunctional thiols, base-catalyzed Michael addition thiols. The highly efficient thiol–acrylate reaction ensures that the molecular weight between...
ABSTRACT Shape‐memory polymers (SMPs) that respond near body temperature are attracting broad interest, especially in the biomedical fields. In this study, triggering of poly(caprolactone) SMP networks is precisely adjusted by inclusion non‐crystallizable molecular linkers and variation prepolymer weight. Longer, non‐crystalline lower weight prepolymers interfere with crystallization, lowering transition temperature. Networks prepared crystallization temperatures beneath human yet above room...
Boron nitride nanosheets (BNNS) were used to anchor bimetallic Pd–Fe nanoparticles for Suzuki–Miyaura coupling catalysts. The found be core–shell in structure, and their formation was likely facilitated by interactions with the BNNS. Pd–Fe/BNNS catalysts highly effective representative reactions, performances matching or exceeding those of state-of-the-art methods. Specifically, superior catalytic activities characterized generally shortened reaction times, minimal Pd usage, excellent...
Hexagonal boron nitride nanosheets (BNNSs) possess ultimate thermal and chemical stabilities mechanical strengths. However, the unmodified BNNSs are hydrophobic insoluble in water, which hinders their use many technological areas requiring aqueous compatibility. In this work, h-BN was treated with molten citric acid to produce dispersible sheets (ca-BNNSs). The resultant ca-BNNSs were used fabricate ca-BNNS/polyacrylamide (i.e., BNNS2.5/PAAm) nanocomposite hydrogels, targeting high water...
