This article provides a comprehensive overview of the machining of aluminum alloys, composites, and ceramics at micro scale. All major aspects of the micromachining of aluminum alloys including process descriptions, key research findings, applications, major challenges, and guidelines for future research have been covered in this article. Based on the literature, conventional micromachining processes, such as turning, milling, grinding, and drilling, have been found to be suitable for machining most of the cast and wrought aluminum alloys. On the other hand, nonconventional micromachining processes were approached for the micromachining of aluminum metal matrix composites and alumina ceramics. Some challenges and aspects in the area of micromachining of aluminum alloys that need future considerations are burr formation, tool wear, surface finish, microstructures and properties changes, and process development for advanced and hybrid micromachining.

Abstract The field of vocabulary research is witnessing a growing interest in the use of eye-tracking to investigate topics that have traditionally been examined using offline measures, providing new insights into the processing and learning of vocabulary. During an eye-tracking experiment, participants’ eye movements are recorded while they attend to written or auditory input, resulting in a rich record of online processing behaviour. Because of its many benefits, eye-tracking is becoming a major research technique in vocabulary research. However, before this emerging trend of eye-tracking based vocabulary research continues to proliferate, it is important to step back and reflect on what current studies have shown about the processing and learning of vocabulary, and the ways in which we can use the technique in future research. To this aim, the present paper provides a comprehensive overview of current eye-tracking research findings, both in terms of the processing and learning of single words and formulaic sequences. Current research gaps and potential avenues for future research are also discussed.

The changing energy landscape in Europe, marked with the development of the Energy Union in 2015, had a profound impact also on the European port sector. With European ports becoming key points of energy production, but also being prominent energy users, energy consumption has naturally risen into a top environmental priority for port authorities. To this end, the paper provides a pragmatic and comprehensive overview of the main policies, technologies and practices that European ports have adopted to-date for enhancing their energy efficiency. Addressing a gap that has been identified in relevant recent literature, it gathers actual data and port experiences from many different sources in a first attempt to better facilitate knowledge and experience-sharing activities, that will support ports in collectively moving towards a zero-emission and climate-neutral future. Most importantly, it presents an effort to rationalize research findings, assist in aligning them with practice, shed more light on the exploitation path of this line of research and better inform future research efforts.
