"Sustainability - Development that meets the needs of the present without compromising the ability of future generations to meet their own needs"
In today's world, society faces the challenge of an ever-increasing demand for energy, goods, and services. Academic research plays a crucial role in addressing these challenges by contributing to the rapid advancement of technologies that can be applied practically. The development of sustainable technologies exemplifies how academic research can drive improvements in technological solutions for the benefit of both humanity and the planet.
As we live in a world where machines produce almost everything, exploring ways to make these machines more efficient and extend their service life is a key approach to saving energy and resources. Improved lubricant technology is crucial in this endeavor.
As a PhD student specializing in machine design, my research focuses on finding more sustainable alternatives to traditional mineral-based lubricants. Bio-based lubricants are promising candidates due to their superior environmental benefits, including high biodegradability, renewability, low toxicity, and low bioaccumulation. However, their technical performance is not always satisfactory, and their high cost limits their widespread adoption. One potential solution is the development of hybrid lubricants that combine mineral and bio-based lubricants, striking a balance between environmental benefits and technical performance. Hybrid lubricants are analogous to hybrid vehicles, which merge the advantages of electric and gasoline-powered cars.
Additionally, my work involves investigating suitable additives for hybrid lubricants. Additives can enhance lubricants by imparting desired properties, but their solubility in lubricants sometimes poses a challenge. Ionic liquids, known for their tunable properties achieved by altering cation and anion combinations, are among the most promising lubricant additives and are being explored in hybrid lubricants to develop more effective solutions.
When considering the future of our grandchildren and their descendants, sustainability must be more than just a buzzword—it requires meaningful action.
