Modifying the microstructure of photocatalysts while simultaneously introducing vacancies has shown significant potential in enhancing their performance for hydrogen production. Herein, a novel tubular mesoporous carbon nitride（TMCN） with nitrogen vacancies was fabricated using a microwave-assisted synthesis strategy, employing melamine-cyanuric acid supramolecular（MC-S） as the precursor. The optimized TMCN exhibited an outstanding H2production rate, approximately 29 times higher than that of pristine g-C3N4. The N-vacancies serve as sites for reactant adsorption and activation, leading to enhanced delocalization of HOMO-LUMO. Furthermore, the porous structures of TMCN facilitate the reactant diffusion, while its tubular architectures promote the oriented transfer of charge carriers. Crucially, the markedly improved photocatalytic performance of TMCN can be predominantly attributed to the synergistic effects arising from its superior structure and N-vacancy defects. This work opens new possibilities for the simultaneous formation of surface defect states as photocatalytic reaction sites and distinctive structures conducive to charge carrier transport.

【目的】研究酸性饲粮对东方蜜蜂微孢子虫繁殖和意大利蜜蜂免疫力的影响,验证酸性饲粮是否能够防治蜜蜂微孢子虫疾病,为在养蜂中合理使用酸性饲料提供科学依据。【方法】以意大利蜜蜂为研究对象,选取400只新出房蜜蜂,随机分为4组,分别为对照组、微孢子虫组、微孢子虫+柠檬酸组(含50 g·L^(-1)柠檬酸)和微孢子虫+醋酸组(含400 mL·L^(-1)醋酸),每组100只,检测并分析感染后第1天和第3天免疫基因的相对表达量,统计分析感染7 d后蜜蜂体内微孢子虫数量和蜜蜂存活率。【结果】4个试验组之间的存活率差异极显著(P0.05)。在微孢子虫组中,蜜蜂感染3 d内检测到11个免疫基因的相对表达量未显著下降(P>0.05),但酸性饲粮处理组中的部分免疫基因PGRPSC4300和Abaecin的表达量显著下降(P<0.05)。【结论】含有50 g·L^(-1)柠檬酸和400 mL·L^(-1)醋酸的饲粮无法抑制微孢子虫繁殖,也不能提高蜜蜂免疫力和存活率,不适用于治疗蜜蜂微孢子虫病。

Rising oil price has brought huge cost pressure for low grade highway construction, and it is urgent to find alternative resources. At the same time, there are nearly 50000-60000 tons of low temperature coal output in inner Mongolia region, China, which has high toxicity and high polluting. To make the low temperature coal be applicable for road constructions, the formaldehyde is used as cross linking agent, the concentrated sulfuric acid is used as catalyst, and the chemical modification of low temperature coal tar pitch in Inner Mongolia region is investigated. The road performance （softening point, penetration and ductility） of modified low temperature coal are tested. Results shown that the road performance of modified low temperature coal is increased significantly. Modification mechanism of low temperature coal is studied by Scanning Electron Microscopy and other analytical tools. Results show that, in the modified low temperature coal, resin content increases and the resin fiber diameter becomes larger with the increasing of formaldehyde content.

Digitization precision analysis is an important tool to ensure the design precision of machine tool currently. The correlative research about precision modeling and analysis mainly focuses on the geometry precision and motion precision of machine tool, and the forming motion precision of workpiece surface. For the machine tool with complex forming motion, there is not accurate corresponding relationship between the existing criterion on precision design and the machining precision of workpiece. Therefore, a design scheme on machine tool precision based on error prediction is proposed, which is divided into two-stage digitization precision analysis crucially. The first stage aims at the technology system to complete the precision distribution and inspection from the workpiece to various component parts of technology system and achieve the total output precision of machine tool under the specified machining precision; the second stage aims at the machine tool system to complete the precision distribution and inspection from the output precision of machine tool to the machine tool components. This article serves YK3610 gear hobber as the example to describe the error model of two systems and basic application method, and the practical cutting precision of this machine tool achieves to 5-4-4 grade. The proposed method can provide reliable guidance to the precision design of machine tool with complex forming motion.
