Abstract With the development of microelectronics towards integration, miniaturization and high power, accumulation heat in this small space has become a serious problem. Therefore, polymer matrix composites with thermal conductivity electrical insulation need to be developed urgently. Here, an ordered oriented boron nitride/silicon dioxide (silica) coated multiwalled carbon nanotubes (BN/SiO 2 @MWCNTs) thermally conductive network was constructed polyvinylidene fluoride (PVDF) by electrostatic spinning technique, subsequently PVDF were prepared hot-pressing. The synergistic effect two-dimensional BN one-dimensional MWCNTs investigated. It found that out-of-plane 30 /SiO @MWCNTs reached 0.4693 Wm −1 K , which 209% higher than pure 10% BN/PVDF composites. in-plane @MWCNts) 1.5642 1055% 40% This is attributed on SiO @MWCNTs. Meanwhile, volume resistivity breakdown strength BN/SiO @MWCNTs/PVDF 3.6 × 10 13 Ω m 47.68 kV/mm, respectively. results indicate have excellent insulating properties, are promising for applications.

Abstract Optical fiber sensors are widely utilized for their precision, stability, adjustable functionality, and minimal signal degradation. They excel in detecting diverse parameters, even challenging situations where conventional may falter. This study aims to create a novel optical sensor capable of concurrently both temperature ultraviolet (UV) radiation. The was fabricated using digital light processing 3D printing technique. photocurable resin the prepared by incorporating thermochromic powder UV-sensitive powders into polyethylene glycol diacrylate hydroxyethyl methacrylate polymer blend multi-material printing. fibers were printed two distinct orientations: horizontal vertical. characterization these carried out measuring transmission reflection customized measurement setups. vertically oriented exhibit more reflectivity, whereas horizontally demonstrate higher transmission, owing layering phenomenon. significant variation spectra, making them ideal dual sensing. A notable change percentage at 600 nm observed temperatures 25℃, 35℃, 45℃, reducing from 12.13 9.5%, 17.31 15.6%, 19.62 17.98% upon exposure UV radiation, respectively. presence radiation fluctuations can be easily distinguished analyzing spectra. proposed provide promising sensing platform applications continuous monitoring detection is required.

A hatching-distance-controlled lattice of 65.1Co28.2Cr5.3Mo is additively manufactured via laser powder bed fusion with a couple periodic and aperiodic arrangements nodes struts. Thus, the proposed has an amorphous-inspired structure in short- long-range orders. From structural perspective, artificial intelligence algorithm used to effectively align lattices various hatching distances. Then, metastable combination exhibits unexpectedly high specific compression strength that only slightly below solid structure. microstructural newly designed lattice, where thermal energy from irradiation mainly concentrated, exhibit equiaxial microstructure. By contrast, struts columnar microstructure, thereby allowing pass through narrow ligaments. The heterogeneous phase differences between nodal strut areas explain strength-deteriorating mechanism, owing undesirable multi-phase development as-built state. However, solid-solution heat treatment form homogeneous bestows even higher strength. Furthermore, electrochemical leaching leads formation nanovesicles on surface microporous system, leading large area. more advanced valve cage for use power plant by using both (i) preserve its mechanical stiffness (ii) actively dissipate generated stress area provided nanovesicles.
