氧原子普遍共存于六方氮化硼(h-BN)吸附剂中。如何利用h-BN中的氧原子以强化其与吸附质之间的相互作用,从而提高材料的吸附性能,是一个亟待解决课题。本文以聚合法构建氧原子晶格内部取代和边缘羟基化修饰的双氧原子位点改性BN(BN‒2O)材料。BN‒2O的边缘羟基氧原子能够增强二苯并噻吩(DBT)与其非均匀表面的π-π作用,从而促进多分子层型吸附过程。实验结果表明,相比边缘羟基取代BN(BN‒OH)材料,BN‒2O材料对燃油中DBT的吸附容量提升了12%。密度泛函理论计算还揭示了BN‒2O晶格内部的氧原子可以通过极化吸附质的方式增强其与BN‒2O之间的偶极作用,进一步提高BN‒2O从富含芳烃的燃油中选择性吸附DBT的能力,使得其在燃油吸附脱硫领域表现出更好的应用前景。吸附结果符合Freundlich模型和准二级动力学模型结果。因此,该聚合法同样可被应用于其他杂原子掺杂体系以提升吸附剂的吸附性能。

Electrical discharge machining (EDM) is a well-known nontraditional manufacturing process to machine the difficult-to-machine (DTM) materials which have unique hardness properties. Researchers have successfully performed hybridization to improve this process by incorporating powders into the EDM process known as powder-mixed EDM process. This process drastically improves process efficiency by increasing material removal rate, micro-hardness, as well as reducing the tool wear rate and surface roughness. EDM also has some input parameters, including pulse-on time, dielectric levels and its type, current setting, flushing pressure, and so on, which have a significant effect on EDM performance. However, despite their positive influence, investigating the effects of these parameters on environmental conditions is necessary. Most studies demonstrate the use of kerosene oil as dielectric fluid. Nevertheless, in this work, the authors highlight the findings with respect to three different dielectric fluids, including kerosene oil, EDM oil, and distilled water using one-variable-at-a-time approach for machining as well as environmental aspects. The hazard and operability analysis is employed to identify the inherent safety factors associated with powder-mixed EDM of WC-Co.
