Hybridization by multi-components in an aerogel is efficient way to make nanoporous robust, high-temperature stable and multifunctional. While the formation of network a liquid-solid phase separation, solid-solid separation between multi-component likely be triggered enthalpy penalty, which would undermine synergistically effects. Here, this work presents copolymerized precursor that simultaneously incorporates two metals one precursor, efficiently suppress potential distinct components...
High-quality reflective screens constitute an important part of multi-layer insulation materials. However, the metal foils currently used as thermal are easily oxidized in oxidizing environment. Nanoscale yttrium oxide exhibits high reflectivity near-infrared (NIR) region, well excellent stability The material also shows potential for application a high-temperature screen. A Y2O3 nanofiber membrane was successfully prepared by electrospinning synthetic polyacetylacetone‑yttrium (PAY)...
Magnetic fibers adsorbent has attracted more and attention because of the large surface area overcoming disadvantages easy agglomeration difficult separation. Adding Fe3O4 nanoparticles into spinning solution followed by electrospinning is a common method to prepare magnetic fibers. In this paper, new sol-gel was developed fibers, which overcame disadvantage low saturation magnetization due limited amount in solution, uneven distribution Through studying effect proportion ethanol solvent on...
Abstract Yttria-stabilized zirconia (YSZ) fiber composites are highly efficient thermal insulating materials; however, the poor shock resistance limits their versatile applications. In present study, YSZ was mixed directly with Al2TiO5 fiber, which had an extremely low expansion coefficient, to prepare YSZ−Al 2 TiO 5 (ZAT) by compression molding and heat treatment. The minimum coefficient of prepared ZAT measured be 7.74×10 −6 K −1 , 26% lower than that (10.42×10 ). It shown maintain...
An efficient organocatalytic Michael/aldol/hemiacetalization cascade reaction for construction of enantioenriched spirocyclic oxindoles fused with tetrahydropyrane has been developed. The desired highly functionalized 5′,6′-dihydro-2′H,4′H-spiro[indoline-3,3′-pyran]-2-one derivatives containing multiple stereogenic centers were obtained in moderate to high chemical yields and stereoselectivities.
Low density, heat‐resistant sponge‐like fiber assembly materials are considered as promising high‐temperature insulation materials. However, the poor structural stability, infrared radiation heat transfer, and complex preparation process limit its further application. Herein, a facile method to create ultralow‐density ZrO 2 –TiO sponges by electrospinning followed treatment is presented. The layered structure treated at 1200 °C have low density of 9.5 mg cm −3 . Moreover, possess high...
High-performance thermally insulating ceramic materials with excellent mechanical and thermal insulation properties are essential for management in extreme environments. In this work, SiO2 was introduced into the crystalline lattice grain boundary of TiO2 to inhibit its phase transition growth. Meanwhile, layered TiO2/SiO2 nanofiber membranes (TS NFMs) were designed prepared. The TS NFMs had lightweight (44 mg/cm3), high tensile strength (4.55 MPa), ultra-flexibility, low conductivity (31.5...
Multiferroic properties of BiFe<sub>1−x</sub>Zr<sub>x</sub>O<sub>3</sub>films can be regulated by controlling the doping amount Zr, and influence phase transition on films is systematically studied.
The inherent brittleness and hydrophilicity of ceramics pose a great challenge to designing reliable structure that can resist mechanical loads moisture in extreme conditions with high temperature humidity. Here, we report two-phase hydrophobic silica–zirconia composite ceramic nanofiber membrane (H-ZSNFM) exceptional robustness high-temperature resistance. For the dual-phasic nanofibers, amorphous silica blocked connection zirconia nanocrystals, lattice distortion was observed due Si ZrO2...
Ultralow-density (35–60 mg·cm–3) Yb2O3 nanofibrous membranes (YbFMs) with a multilayer structure were successfully prepared for the first time using Yb-acetylacetone coordination polymer as precursor. Thanks to high ceramic yield (62.1%) and excellent spinnability of precursor, YbFMs exhibited outstanding flexibility, which does not cause damage even when bent or knotted. The tensile strength was 1.69 MPa, maximum elongation could reach 33%. Notably, robust fatigue resistance, retaining...
