During pregnancy, the human body is quite vulnerable to external stimuli. Zinc oxide nanoparticles (ZnO-NPs) are widely used in daily life, and they enter via environmental or biomedical exposure, thus having potential risks. Although accumulating studies have demonstrated toxic effects of ZnO-NPs, few addressed effect prenatal ZnO-NP exposure on fetal brain tissue development. Here, we systematically studied ZnO-NP-induced damage underlying mechanism. Using vivo vitro assays, found that...
Linear dielectric polymers are potential candidates for electrostatic capacitors due to their high breakdown strength, efficiency, and low loss. In this work, a novel poly (vinylidene fluoride) (PVDF) tailored linear PMMA-co-GMA (MG) copolymer-based all-organic film with strength discharge energy density was prepared by the solution blending method. Compared PMMA homopolymer, MG copolymer behaved higher (5.6 J/cm3) since GMA component bestowed polarity yielded deep traps copolymer. On other...
ABSTRACT Enhancing the dielectric properties of polymer materials plays a crucial role in reducing volume, weight, and cost capacitors. In this work, polyurethanes (PUs) for high performance were fabricated using poly(tetramethylene ether glycol) (PTMG) polycarbonate diol (PCDL) as soft segments hexamethylene diisocyanate (HDI), isophorone (IPDI), 4,4′‐diphenylmethane (MDI), toluene (TDI) hard segment components. The effects type chemical structure on microphase separation, crystallization,...
With the development of modern power systems, advanced energy storage polymer films are receiving attention. As an important dielectric material, polypropylene (PP) film has advantages low loss and high charge/discharge efficiency. Nevertheless, its inherent constant (∼2.0) severely hampers enhancement density (∼1–2 J/cm3). Herein, all-organic PP-based ternary composite with "sea–island" structure were designed to improve properties PP. In this research, PP formed sea phase. contrast, methyl...
Self-homodyne detection (SHD) is a promising approach to realize high-capacity short-reach optical transmission systems with low cost and power consumption. We experimentally demonstrate single-carrier net 800-Gb/s SHD low-cost ∼MHz linewidth distributed feedback (DFB) laser over 2 km, 10 25 40 km single-mode fiber (SMF) using three different quadrature amplitude modulation (QAM) formats, including 80-Gbaud dual-polarization (DP) 64QAM, 100-Gbaud DP-32QAM, 120-Gbaud DP-16QAM. Among them,...
Background Teachers with high educational levels significantly impact the health-related knowledge and attitudes of young students their family members. This study aimed to investigate coronavirus disease 2019 (COVID-19) vaccine hesitancy associated factors, compare differences between decision-makers non-decision-makers among college teachers.Methods A cross-sectional online survey was administered across mainland China from 4 7 August 2021. Overall, 251 teachers were included using...
Linear MG reduced the loss and improved efficiency of PVDF. CR-C enhanced E b films due to its high modulus formation hydrogen bonds. Multiple bonding restricts carrier migration boosts trap energy. The film achieved a discharge energy density 24.43 J cm −3 .
In order to develop polypropylene (PP) based dielectric materials with high and energy storage properties, PP grafted polystyrene films (PP-g-PS) different grafting content have been prepared by electron beam irradiation method. Free radicals were generated in the chains during also enhanced polarity of due oxidation reaction. The results shown that presence PS introduced smaller spherical crystals, which led more interfacial regions increased polarization. DFT simulations TSDC proved deeper...
Polymer-based dielectric materials have been used in film capacitors due to their rapid charge-discharge rate, lightness, and low cost. Nevertheless, the energy storage properties of these films were limited by weak polarization ability discharge density. Herein, solution casting method was prepare all-organic crosslinked composite using linear methyl methacrylate-co-glycidyl methacrylate (MG) as matrix ferroelectric poly(vinylidene fluoride) (PVDF) organic filler. The MG networks can...
An active reconfigurable intelligent surface (RIS) has been shown to be able enhance the sum-of-degrees-of-freedom (DoF) of a two-user multiple-input multiple-output (MIMO) interference channel (IC) with equal number antennas at each transmitter and receiver. However, for any receive transmit antennas, when how an RIS can help improve sum-DoF are still unclear. This paper studies RIS-assisted MIMO IC arbitrary antenna configurations. In particular, beamforming, zero-forcing, decoding...
To examine the effectiveness of decortication to treat chronic tuberculous empyema (TE) using uniport video-assisted thoracoscopic surgery (VATS) versus conventional triport VATS.Data from consecutive patients with stage II or III TE who underwent either VATS (uniportal group) between July and December 2017, January 2018 (triportal group), were retrospectively analysed. procedures performed under general anaesthesia double lumen endotracheal intubation clinical outcomes compared two...
