Insulating thermally conductive polymer composites are in great demand integrated-circuit packages, for efficient heat dissipation and to alleviative short-circuit risk. Herein, the continuous oriented hexagonal boron nitride (h-BN) frameworks (o-BN@SiC) were prepared via self-assembly situ chemical vapor infiltration (CVI) interface welding. The insulating o-BN@SiC/epoxy (o-BN@SiC/EP) exhibited enhanced thermal conductivity benefited from CVI-SiC-welded BN-BN interface. Further, multiscale...
High stability single- and dual-wavelength compound cavity erbium-doped fiber lasers (EDFLs) with ultra-narrow linewidth, high optical signal to noise ratio (OSNR) widely tunable range are demonstrated. Different from using traditional cascaded Type-1/Type-2 rings as secondary cavities, we nest a Type-1 ring inside Type-2 form passive subring achieve single-longitudinal-mode (SLM) lasing linewidth for the first time. We also show that SLM can be further improved by inserting length of...
To be the wound dressings that alleviate progressive thermal injury, hydrogels require to have high conductivity, excellent mechanical properties, and outstanding biocompatibility, which are hard achieve simultaneously. Inspired by multiscale structure of spider silk, we developed a hierarchical hydrogel architecture. This architecture includes molecular-scale hydrogen bonds between oxygen plasma-treated graphene fibers (OPGFs) poly(vinyl alcohol) (PVA), as well within PVA molecular chains....
Halide perovskite light-emitting diodes (PeLEDs), considered as potential candidates for future displays, face significant limitations in their external quantum efficiency (EQE) due to an uncontrollable nucleation and crystallization process. Herein, a close-space inverted annealing (CSIA) strategy is developed achieve fast obtain more uniform film with larger crystal domains much lower defect centers. The increased surficial temperature quick solvent evaporation the CSIA method result...

Currently, polyimine vitrimer is restricted by unitary functionality and poor responsiveness to external stimuli, thus showing limited potentials for broader applications as a kind of smart material. Herein, we reported thermal, near-infrared light, amine solvent triple-responsive (ACAT-vitrimer) incorporating oligoaniline into traditional imine-type through the polycondensation reaction terephthaldehyde, m-xylylene diamine, tris (2-aminoethyl) amine. The material exhibited superior...

We report what we believe to be the first quantitative determination of strain-induced birefringence variations in polarization maintaining fibers (PMFs). The measurement method is based on ghost-peak-free scanning white light interferometer distributed crosstalk analysis technique with two fusion-splicing-induced reference peaks, as variation causes a change spacing between peaks. Two types commercial PMF samples (Panda and Bow-tie) are measured experimental data fitted linear equation...
