Electromagnetic wave(EMW)absorbing materials have an irreplaceable position in the field of military stealth as well as in the field of electromagnetic pollution control.And in order to cope with the complex electromagnetic environment,the design of multifunctional and multiband high efficiency EMW absorbers remains a tremendous challenge.In this work,we designed a three-dimensional porous structure via the salt melt synthesis strategy to optimize the impedance matching of the absorber.Also,through interfacial engineering,a molybdenum carbide transition layer was introduced between the molybdenum selenide nanoparticles and the three-dimensional porous carbon matrix to improve the absorption behavior of the absorber.The analysis indicates that the number and components of the heterogeneous interfaces have a significant impact on the EMW absorption performance of the absorber due to mechanisms such as interfacial polarization and conduction loss introduced by interfacial engineering.Wherein,the prepared MoSe_(2)/MoC/PNC composites showed excellent EMW absorption performance in C,X,and Ku bands,especially exhibiting a reflection loss of−59.09 dB and an effective absorption bandwidth of 6.96 GHz at 1.9 mm.The coordination between structure and components endows the absorber with strong absorption,broad bandwidth,thin thickness,and multi-frequency absorption characteristics.Remarkably,it can effectively reinforce the marine anticorrosion property of the epoxy resin coating on Q235 steel substrate.This study contributes to a deeper understanding of the relationship between interfacial engineering and the performance of EMW absorbers,and provides a reference for the design of multifunctional,multiband EMW absorption materials.

Confronted with severe electromagnetic wave pollution,the development of high-performance electromagnetic wave shielding or absorbing materials is an effective way to deal with it.Notably,double transition metal alloys and transition metal dichalcogenides have attracted extensive attention in electromagnetic wave absorption,but few reports have studied the effects of these two materials on electromagnetic wave absorption at the same time.In this work,cobalt-based alloy with magnetic loss mechanism was selected for composition optimization.The ternary metal-organic framework was prepared by the one-step method,and then CoCu/C was prepared by high temperature annealing.Finally,in the hydrothermal process,ultra-thin tungsten selenide nanosheets were coated on the surface of magnetic component,and the final polyhedral WSe_(2)/CoCu/C composites with multiple heterogeneous interfaces were obtained.The synergistic effect of dielectric and magnetic components optimizes impedance matching and allows more electromagnetic waves to enter the absorber.Subsequently,through the conduction loss of high conductivity graphitized carbon,interfacial polarization,and dipole polarization of heterogeneous interfaces between the components,the magnetic loss provided by CoCu alloy can work together to maximize the attenuation ability of electromagnetic waves.Exactly,the minimum reflection loss(RLmin)value of the composite reaches-53.43 dB when the matched thickness is 2.1 mm,while the maximum effective absorption bandwidth(EABmax)reaches 6.0 GHz at a thin thickness of 1.8 mm.This work provides some support and reference for the design of novel electromagnetic wave absorbing materials via the dielectric/magnetic loss synergistic mechanism.

Astaxanthine(AST) has important biological activities including antioxidant and antiinflammatory effects that could alleviate neurological and heart diseases, but its role in the prevention of cisplatin-induced hearing loss(CIHL) is not yet well understood. In our study, a steady interaction between AST and the E3 ligase adapter Kelch-like ECH-associated protein 1, a predominant repressor of nuclear factor erythroid 2-related factor 2(NRF2), was performed and tested via computer molecular docking and dynamics. AST protected against cisplatin-induced ototoxicity via NRF2 mediated pathwayusing quantitative PCR and Western blotting. The levels of reactive oxygen species(ROS) and mitochondrial membrane potential revealed that AST reduced ROS overexpression and mitochondrial dysfunction.Moreover, AST exerted anti-apoptosis effects in mouse cochlear explants using immunofluorescence staining and HEI-OC1 cell lines using quantitative PCR and Western blotting. Finally, AST combined with poloxamer was injected into the middle ear through the tympanum, and the protection against CIHL was evaluated using the acoustic brain stem test and immunofluorescent staining in adult mice. Our results suggest that AST reduced ROS overexpression, mitochondrial dysfunction, and apoptosis via NRF2-mediated pathway in cisplatin-exposed HEI-OC1 cell lines and mouse cochlear explants, finally promoting cell survival. Our study demonstrates that AST is a candidate therapeutic agent for CIHL.

共享道路空间中的人类驾驶交互行为具有兼顾伴行车损益的社会性特征。由于对驾驶交互社会性的理解缺失,自动驾驶车辆往往难以估计自身行为对伴行车辆的潜在影响,因而陷入“被迫保守”的决策困境。本文在博弈论框架中引入驾驶人兼顾伴行车损益的行为特征,构建社会性驾驶交互行为模型,刻画了驾驶交互中个体间的动作依赖关系。结合该模型,提出主车预期行为对其交互对象所造成潜在影响的通用定量表达——交互效用项。通过在规划目标中引入交互效用项,可定向调整运动规划算法的交互主动性。高速路出匝道实验结果表明,在对安全性无显著影响的前提下,通过提升交互主动性,基于优化和基于采样的运动规划算法在给定距离内出匝道任务成功率可分别提升3.9%与5.2%。

Food Science and Human Wellness 2021年第1期10卷 112-118页

作者： zirui zhao Shujie Wang Dayu Li Yajun Zhou College of Biological and Agricultural Engineering Jilin UniversityChangchun130025China Department of Food Science and Engineering Jilin UniversityChangchun130062China

The effects of xanthan gum (0 % and 0.3 %) on the quality of low sodium (2.0 %, 2.4 %, 2.8 %, 3.2 %, 3.6 % and 4.0 %) salted beef and property of myofibril proteins (MP) extracted from salted beef were researched. Changes in the salting absorptivity, cooking loss, shear force, color and sensory analysis showed that xanthan gum had a positive effect on the quality of salted beef with low salinity (2.0 %, 2.4 % and 2.8 %). MP of salted beef treated with xanthan gum had higher solubility, lower hydrogen bond than that without it (P < 0.05). The decrease of surface hydrophobicity and intrinsic fluorescence intensity indicated that the chromophore of protein was brought into a hydrophobic environment in the presence of xanthan gum. The electrophoresis showed that xanthan gum could improve the concentration of myosin heavy chain, paramyosin and actin after tumble-salting. The data suggested that salted beef and its MP treated with xanthan gum and 2.8 % salt (XS3) had the best properties. Together, xanthan gum could be considered as a sodium salt substitute for the development of low sodium meat products.

Investigation on the adhesive contact and electrical performance for triboelectric nanogenerator considering polymer viscoelasticity

引用

Nano Research 2021年第12期14卷 4625-4633页

作者： Chenfei Wang Xiaoli Wang Yanqiang Hu Lizhou Li Zhihao Li Heng Wu zirui zhao Department of Mechanical Engineering Beijing Institute of TechnologyBeijing100081China

The triboelectric nanogenerator(TENG)is a new mechanical energy harvesting technology in which the typical viscoelastic material polydimethylsiloxane(PDMS)is widely used.Micro-/nano-textures are often fabricated on the PDMS surface to enhance the electrical performance of TENG.As the contact region decreases to micro/nano scale,the adhesive forces become dominant.However,there is still a lack of contact mechanics model considering both material viscoelasticity and the adhesive forces to guide the surface texture design.In this paper,the explicit data-fitting formulas based on the fractional derivative Zener model are firstly derived to identify the viscoelastic constitutive parameters,which can not only avoid the influence of the initial contact point,but also ensure the accurate conversion between the creep compliance and the relaxation modulus function.Then a viscoelastic-adhesive contact model based on the fitted constitutive parameters is established,and the numerical algorithms such as bi-conjugate stabilized(Bi-CGSTAB)method and fast Fourier transform(FFT)technique are employed to analyze the effects of material viscoelasticity and texture sizes on the contact and electrical performance.It is shown that,compared with results from the elastic-adhesive contact model,the contact area ratio based on the viscoelastic-adhesive contact model is significantly larger,which is much closer to the experimental results.Among the selected sizes of pyramid texture,the higher electrical performance can be obtained from the textures with a smaller pitch and a larger width under the heavier applied load.This study can provide a theoretical reference for the design of viscoelastic surface texture of TENG.
