Marine biofouling seriously affects human marine exploitation and transportation activities, to which marine antifouling(AF) coatings are considered to be the most cost-effective solution. Since the mid-20th century, human beings have dedicated their efforts on developing AF coatings with long cycle and high performance, leading to a large number of non-target organisms? distortion, death and marine environmental pollution. Polydimethylsiloxane(PDMS), is considered as one of the representative environment-friendly AF materials thanks to its non-toxic, hydrophobic, low surface energy and AF properties. However, PDMS AF coatings are prone to mechanical damage, weak adhesion strength to substrate, and poor static AF effect, which seriously restrict their use in the ocean. The rapid development of various nanomaterials provides an opportunity to enhance and improve the mechanical properties and antifouling properties of PDMS coating by embedding *** on our research background and the problems faced in our laboratory, this article presents an overview of the current progress in the fields of PDMS composite coatings enhanced by different nanomaterials, with the discussion focused on the advantages and main bottlenecks currently encountered in this field. Finally, we propose an outlook, hoping to provide fundamental guidance for the development of marine AF field.

Research on perturbation of neutron fluence rate in a closed thermal neutron field due to medium materials

NUCLEAR SCIENCE AND TECHNIQUES 2024年第10期35卷 1-11页

The neutron radiation field has vital applications in areas such as biomedicine, geology, radiation safety, and many others for neutron detection and neutron metrology. Correcting neutron fluence rate perturbation accurately is an important yet challenging problem. This study proposes a correction method that analyzes three physical processes. This method, which transforms the detection process from point detection to area detection, is based on a novel physical model and has been validated through theoretical analyses, experiments, and simulations. According to the average differences between the calculated and experimental results, the new method (1.67%) demonstrated better accuracy than the traditional simulation (2.17%). In a closed thermal neutron radiation field, the detector or strong neutron absorption material significantly perturbs the neutron fluence rate, whereas its impact on the energy spectrum shape and neutron directionality is relatively minor. Furthermore, based on the calculation results of the perturbation rate formula for medium materials with different compositions and sizes, the larger the volume and capture cross section of the medium, the higher the perturbation rate generated in the closed radiation field.

陌生人间的合作行为对于解决社会公共问题,应对世界百年未有之大变局意义重大。本研究采用横断历史元分析方法,基于1999~2019年间开展的254项使用社会困境范式测量我国陌生人间合作行为的研究(共302个合作率,29249名被试,平均年龄:18~28岁),探讨了中国社会中合作行为的变迁及一些社会发展指标在其中的解释作用,并比较中美两国的合作行为变迁趋势。结果表明,中国人的合作行为水平随时间而上升,一些社会发展指标(人均国内生产总值、城市化率、高等教育水平、互联网普及率等)可能是其上升的社会变迁基础。中美两国合作行为表现出相似的上升趋势,但中国的在更短时间内有更大上升幅度。研究结果对提振民众信心具有重要意义。
