Hydrogen peroxide(H_(2)O_(2)) is a high-demand organic chemical reagent and has been widely used in various modern industrial applications. Currently,the prominent method for the preparation of H_(2)O_(2) is the anthraquinone ***, it is not conducive to economic and sustainable development since it is a complex process and involves unfriendly environment and potential hazards. In this context, numerous approaches have been developed to synthesize H_(2)O_(2). Among them, photo/electro-catalytic ones are considered as two of the most promising manners for on-site synthesis of H_(2)O_(2). These alternatives are sustainable in that only water or O_(2) is required. Namely, water oxidation(WOR) or oxygen reduction(ORR)reactions can be further coupled with clean and sustainable energy. For photo/electro-catalytic reactions for H_(2)O_(2) generation, the design of the catalysts is extremely important and has been extensively conducted with an aim to obtain ultimate catalytic performance. This article overviews the basic principles of WOR and ORR,followed by the summary of recent progresses and achievements on the design and performance of various photo/electro-catalysts for H_(2)O_(2) generation. The related mechanisms for these approaches are highlighted from theoretical and experimental aspects. Scientific challenges and opportunities of engineering photo/electro-catalysts for H_(2)O_(2) generation are also outlined and discussed.

Characterization of bonding property in asphalt pavement interlayer: A review

引用

Journal of Traffic and Transportation Engineering(English Edition) 2021年第3期8卷 374-387页

Higher requirements are put forward for interlayer bonding property with the increase of traffic load, including bearing capacity and durability. Typical diseases caused by insufficient adhesion between layers are slippage cracking, de-bonding and pavement deformation. The correct characterization of bonding property becomes necessary with evolving concerns of interlayer failure and material innovations. In the past forty years, many researches have focused on the evaluation of interlayer bonding property, and some valuable conclusions have been drawn. In this review, the mechanism, evaluation method and influencing factors of the interlayer bond strength are reviewed. The common test equipment can be classified into the shear, pull-off and torsion test. Different influence factors are analyzed including tack coat property, temperature, asphalt aging and surface condition. It is recommended to select the appropriate tack coat rate, and apply the tack coat under the conditions of clean, dry, high surface texture and good compaction. However, the interlayer failure mechanism and the interaction between the different influencing factors need to be further studied. The future work can focus on the correlation between different test methods and evaluation parameters, which would address the lack of harmonization or consistency among various evaluation approaches. Meanwhile, it is significant to add the evaluation of interlayer bonding property into the system of pavement design.

Lifespan of Solutions to MHD Boundary Layer Equations with Analytic Perturbation of General Shear Flow

引用

Acta Mathematicae Applicatae Sinica 2019年第1期35卷 209-229页

作者： Feng XIE tong yang School of Mathematical Sciences and LSC-MOE Shanghai Jiao Tong University Department of Mathematics City University of Hong Kong School of Mathematical Sciences Shanghai Jiao Tong University

In this paper, we consider the lifespan of solution to the MHD boundary layer system as an analytic perturbation of general shear flow. By using the cancellation mechanism in the system observed in [12], the lifespan of solution is shown to have a lower bound in the order of ε^(-2-) if the strength of the perturbation is of the order of ε. Since there is no restriction on the strength of the shear flow and the lifespan estimate is larger than the one obtained for the classical Prandtl system in this setting, it reveals the stabilizing effect of the magnetic field on the electrically conducting fluid near the boundary.
