In our laboratory, based on "Tribology" which is regarding the friction wear and lubrication technology, we are conducting research on mechanical elements often used in automobiles, energy equipment, information equipment, robots, etc., especially bearings used for reducing the friction in many types of machinery. In addition, there are many joint research projects with companies, such as research related to environmental issues. In recent years, we have been paying attention to the relationship between engineering and tribology, which specializes in ne structures, microbubbles, and ne droplets.ResearchAreasEngineeringKeywords■Tribology■Machine Design■Bearing□Optimization□BiomimeticsRelatedresearchSDGOptimum design for improving the characteristics of machine elements. Visualization of high-speed and microscale uid ow in many devices. Development of micro air vehicle and some devices by biomimetics.ProfessorMasayuki OchiaiUndergraduate School of EngineeringDepartment of Mechanical EngineeringMaintenance and replication of physiological functions of cells cultured in vitro are extremely difficult in conventional cell-based assay methods during life science and medical applications. Microfluidics is an emerging technology with the potential to provide integrated environments for maintenance, control, and monitoring the environment around cells. We work mainly in fundamental technologies of microuidic devices and systems, and their applications to biological sciences including Microphysiological systems. A physiological environment in vitro can be replicated by fabrication of microstructures and control of microfluidics in these devices. Because cells cultured in vitro could be maintained and measured, these devices may be applied to medical, pharmaceutical and biological sciences.The main focus of our research is on nanomaterials, their preparation and use for various applications. Among other approaches, in our lab we apply the laser ablation in liquid phase technique to prepare various nanomaterials by ablating (or irradiating) solid targets immersed or suspended in liquids. Nanoparticles of metals, metal oxides and metal suldes, as well as hybrid nanosturctures, with dierent sizes and morphologies are generated. The produced nanostructures are then characterized and tested as candidates for potential use in different fields (e.g., as photocatalysts, materials for electrocatalytic splitting of water, gas sensors and biosensors, antibacterial agents for biomedicine, etc.).
