燃料电池作为新型清洁能源技术具有高效的能源转化效率和环境友好等优点,在诸如交通运输以及航空航天等领域有着重要而广泛的应用。在影响燃料电池性能的众多因素中,电极的高效催化与稳定性对于整个燃料电池系统的性能至关重要。近年来,石墨烯材料由于优异的电学与力学性质为低铂高效催化研究提供了理论上的可行性。本研究以六氯环三磷腈(HCCP)为原料设计了一步热还原合成法实验制备了磷氮双掺杂石墨烯,并通过添加碳纳米颗粒增加了石墨烯层间间距,改善了石墨烯层间的团聚效应,提高了氧化还原(ORR)性能。研究结果表明,当AC添加含量与GO的质量比为10%时,其比表面积与电化学性能提升最为明显,极限电流密度达到?6.89 mA·cm?2并且氧化活性能保持80%以上。因此,使用添加碳纳米颗粒对磷氮双掺杂石墨烯作为燃料电池非金属催化剂材料的进一步探索具有巨大的潜力。

为了研究水平夹套式热管内部的沸腾冷凝过程,采用Fluent软件选用Mixture多相流模型对气液两相流进行数值模拟。通过径向热管热阻模型描述热管内部的传热过程。由于热管涉及到复杂的蒸发冷凝传热传质现象,需要对模型加载UDF自定义函数,从而得到稳定的相变瞬态过程。模拟计算得到稳定状态下的管内温度分布,以及液池蒸发现象和凝结液膜的形成过程,并计算出液膜厚度同局部换热系数之间的关系。模拟计算所得到的外壁温度同实验结果相互吻合,表明通过编写UDF程序及选取Mixture模型建立的数值模拟,可以对管内流体的蒸发冷凝进行模拟,并能详细地计算出热管内部相态的变化规律。文章中的研究结果对热管的优化设计提供了有价值的参考。

Microplastics pollution and seawater temperature rise have been the major environmental issues,threatening the survival and biodiversity of marine *** study evaluated the combined effect of temperature and polystyrene microplastics(MP)on Artemia,a filter-feeding crustacean that is widely used for environmental toxicology *** shrimp Artemia franciscana were exposed to three MP concentrations(0,0.2,and 2.0 mg/L)and three temperatures(22,26,and 30℃)for 14 *** general,higher MP concentration and temperature led to a decreased survival rate and ***-way ANOVA analysis indicated that the survival rate of Artemia was significantly impacted by both MP concentration and temperature(P0.05).Growth of Artemia was significantly impacted by temperature(P<0.05),and with a significant interaction between two factors(P<0.05).Furthermore,the enzymatic activity,intestinal histological analyses,and immune gene expression were determined for Artemia reared at 30℃ with three MP concentrations(0,0.2,and 2.0 mg/L).The results showed that 2.0-mg/L MP resulted in reduced Artemia intestinal microvilli and exfoliated epithelia cells,significantly increased acid phosphatase(ACP)activity(P<0.05)and immunerelated gene ADRA1 B and CREB3 expression,revealing that higher MP concentration could induce oxidative and immunological stress on Artemia at 30℃.Overall,our study suggests that MP and temperature have combined adverse effect on Artemia,especially at relatively high temperature and polystyrene MP *** findings are important to understand the potential ecological risks posed by these two factors on the organisms in marine environment.

The V72Ti18Cr10alloy was prepared by a co-precipitation-reduction method in order to consume less energy during whole-life alloy manufacturing, and the phase evolution process in hydrogenation/dehydrogenation process was investigated. The structure refinement analysis of the alloy contented with 1 wt% hydrogen after hydrogenation shows that BCC phase, BCC-hydride phase and FCC phase coexisted, but little BCT phase was found. It indicates that the phase evolution process during hydrogenation was BCC→ BCC-hydride→ FCC,nevertheless the formation of BCT phase was restrained. The limited particle sizes of the alloy in the range of 0.1–5 μm and fewer defects than the normal alloy ingot contributed to the suppression of BCT formation. The annealed alloy, which had similar particle sizes with the unannealed alloy, has less unevenness of the compositions than the unannealed alloy, and the annealed alloy showed flatter plateau in the hydrogenation PCT(pressure-composition-temperature) curves. However, the BCT phase in the annealed alloy appeared in its dehydrogenation process owing to the produced defects during the following dehydrogenation and the hydrogenation process. The alloy with the limited particle sizes even in the range from 0.1 μm to 5 μm could not prevent the generation of BCT phase in the dehydrogenation process.
