Severe plastic deformation(SPD)-induced gradient nanostructured(GNS)metallic materials exhibit supe-rior mechanical performance,especially the high strength and good ductility.In this study,a novel high-speed machining SPD technique,namely single point di
High entropy pyrochlores(HEP)are potential candidates as dispersoids in the oxide dispersed strength-ened steels or alloys,which can be used in nuclear reactors and supercritical boilers.For the first time,HEP oxides Y2(TiZrHfMoV)2O7 were synthesized with
It is a challenge to reduce the dielectric loss and increase the tunability of pure barium strontium titanate(BST)films for microwave tunable application because these two properties change simultaneously.Herein,a novel composite of strontium titanate(ST)
Using natural product-based antifouling coatings has proven to be an effective strategy to combat biofoul-ing.However,their antifouling mechanisms are still unclear.In this study,the antifouling mechanism of natural product-based coatings consisting of bi
Hetero-structured thermally conductive spherical boron nitride and boron nitride nanosheets(BNN-30@BNNS)fillers were prepared via electrostatic self-assembly method.And the corresponding thermally conductive&electrically insulating BNN-30@BNNS/Si-GFs/E-44
Increasing occurrence of intrinsically antimicrobial-resistant,human pathogens and the protective biofilm-mode in which they grow,dictates a need for the alternative control of infectious biofilms.Biofilm bacteria utilize dispersal mechanisms to detach pa
Polymer-dispersed liquid crystal(PDLC)films comprising polyvinyl alcohol(PVA)and liquid crystal monomer(LCM)were successfully obtained by the method of solution casting&thermal compress-ing.LCM was distributed orderly in PVA matrix by hydrogen bond intera
High-strength bainitic steels have created a lot of interest in recent times because of their excellent com-bination of strength,ductility,toughness,and high ballistic mass efficiency.Bainitic steels have great potential in the fabrication of steel armor
Crystal defect engineering is widely used as an effective approach to regulate the optical and opto-electronic properties of semiconductor nanostructures.However,photogenerated electron-hole pair recombination centers caused by structural defects usually
通过热重实验,从还原温度、还原气氛及还原时间三方面对含碳球团的还原特点和动力学进行了研究,采用界面反应模型、三维扩散模型等对含碳球团还原过程进行拟合.研究表明:在本实验条件下,当温度为1100℃、气氛为单一H2、还原时间为60 min时,反应分数达到最大值0.81,还原效果最佳;还原过程中,还原速率先迅速增大,随后逐渐减小;当假设扩散模型为还原过程的限制性环节时,得到的拟合效果最好,反应活化能为93.18 kJ/mol.
