I hope your January is going well. I always think it will be a steady return to work but it never is. There’s always so much to do and at this point, I should just admit that I’m terrible at fooling myself in how the first few weeks of January will go. It has been good to get the ball rolling with work again however and recently my coauthors and I recently received good comments back on an article. Along with the many training courses I’ve been undertaking, this has made me reflect on the academic writing process. Academic writing is both challenging and extremely rewarding, having to balance data analysis, narrative and discussion with respect to the field in question. Despite the arduousness of the peer review process, the satisfaction of having an article accepted and go to print never gets old.
For aerospace and other extreme environments, solid lubricants and key to increasing performance. Graphene and molybdenum disulphide are extremely promising for this application as they can both offer extremely low friction however environmental effects must be further explored to optimise performance. An investigation on the tribological properties of multilayer graphene and MoS2 nanosheets as additives used in hydraulic applications by Zhao et al. aims to expand on the reported tribological behaviour of these materials.
Abstract:
Recently, we have proposed an Electro-hydrostatic-actuator (EHA) based on a novel linear oscillating motor, which permits nanoparticle additives, such as layered graphene and MoS2, using in hydraulic oil. Especially under a super smooth (Ra~5 nm) surface unlike past studies, the tribological properties of these additives is sent more highlight. In addition, oil temperature is introduced into the friction process. We show that the friction coefficient can be decreased to as low as 0.04 when adding MoS2 nanaosheets for the chemical absorption and forming “available solid lubricant” under smooth surface and high temperature while multilayer graphene performs relatively unstable tribological properties because of agglomerates and crystal defects. It can be concluded that MoS2 nanosheets possess better potential value for the application.
The increased access to education across the globe is without a doubt a benefit to us all with improved outcomes for the individual and great social and economic growth. Though the share of the global population with no education is falling there are still many areas where literacy rates are still low.

There is an increasing push towards the open-access model of publishing allowing greater access to research for scientists and the general public. The Directory of Open Access Journals is a community-curated online resource providing access to high quality, peer-reviewed journals.
