Coronavirus disease 2019 (COVID-19) pandemic has spread in 220 countries/regions to wreak havoc human beings around the world. At present, second wave of COVID-19 begun many European countries. The complete control is very urgent. Although China quickly brought virus under control, there have been eight sporadic outbreaks since then. Both Xinfadi Beijing and Dalian outbreak COVID-19, environmental swab samples related imported cold chain food were tested nucleic acid positive for SARS-CoV-2....
Abstract Hexagonal boron nitride nanosheets (h‐BNNSs) are obtained by a chemical exfoliation method from bulk h‐BN powders. The surface of h‐BNNSs is functionalized with 3‐aminopropyltriethoxysilane (APTS). Further, the amino functional groups on APTS‐modified (APTS‐BNNSs) reacted 4‐carboxyphenylboronic acid (CPBA) to obtain covalently linked CPBA‐BNNSs. morphology and structure h‐BNNSs, APTS‐BNNSs, CPBA‐BNNSs comprehensively discussed. Of all above four additives, can most outstandingly...
The increase in energy consumption and its collateral damage on the environment has encouraged development of environment-friendly ceramic materials with good storage properties. In this work, (1–x)Na0.5Bi0.5TiO3-xCa(Mg1/3Nb2/3)O3 ceramics were synthesized by solid-state reaction method. 0.88Na0.5Bi0.5TiO3-0.12Ca(Mg1/3Nb2/3)O3 exhibited a high recoverable density 8.1 J/cm3 efficiency 82.4% at 550 kV/cm. introduction Ca(Mg1/3Nb2/3)O3 reduced grain size increased band gap, thereby enhancing...
Abstract SiOC ceramics have been successfully synthesized using photosensitive resin as a liquid precursor through digital light processing 3D printing technology and pyrolysis. Liquid has excellent fluidity (processable viscosity 0.068 Pa⋅s) which is beneficial for printing. The formulation was designed without solvent filler. After researching the ratio of raw materials temperature conditions, ceramic with complex structures can be produced cracks. were characterized by SEM, XRD, Raman...
Summary of main observation and conclusion Paraffin, as an excellent phase change material (PCM), is limited by the leakage problem low thermal conductivity. In this research, a novel paraffin/neopentyl glycol dimethacrylate/boron nitride (paraffin/NPGDMA/BN) composite PCM was successfully prepared via physical mixing process. NPGDMA in paraffin/NPGDMA/BN cured UV light under action photo initiator, which can improve shape stability to avoid paraffin process change. By comparing rate, latent...
Piezophotonics is a great interesting field of physics that has led to number important technologies, such as light source, smart sensors, and mechatronics. In this work, we reported Pr-doped (Bi0·5Na0.5)TiO3-based lead-free ceramics with strong red photoluminescence emission large strain response (d33∗ = 460 pm/V, S 0.32 %). The PL can be quenched by decreasing the intensity 93 % after electrical polarization (E 50 kV/cm). local structure electric field-induced structural changes were...
Abstract Enhancing the heat dissipation capacity of polymer‐based composites requires effectively improving compatibility filler in a polymer matrix. Herein, hydroxylated boron nitride (BN‐OH) and modified polystyrene (mPS) are combined to achieve high thermal conductive BN‐OH@mPS composite by using facile in‐situ polymerization. Due strong interface interaction between BN‐OH mPS, proposed can have conductivity (TC). Specifically, TC containing 10 wt% reach 1.231 W/mK, which is 142% higher...
The structure and electrical properties of CaCu3Ti4O12 (CCTO) ceramics doped with xHo2O3 synthesized by solid-phase reaction method were systematically studied. Insights from X-ray diffraction (XRD) measurements indicate the existence a primary phase CCTO in all samples. Ho2O3 dopant was found to inhibit grain growth thus leading reduced size ceramics. Moreover, distribution resistivity temperature revealed manifestation negative coefficient (NTC) effect More specifically, (ρ20) values...
