In Fall 2022, Turja Nandy received Graduate Student Research Travel Award for presenting IEEE conference paper (in-person). This award is given by Marquette University Graduate School.
During October 23-26, 2022, Turja Nandy attended The 67th IEEE Holm Conference on Electrical Contacts held in Tampa, Florida. He presented one oral presentation in the technical session: Nano and Micro Scale Systems.
The talk was presented on March 20, 2020, where the design, fabrication, and testing of microelectromechanical systems (MEMS), metal-contact, micro-switches and the issues associated with performance and reliability were discussed. Specifically, unstable electrical contact resistance reduces micro-switch performance and severely degrades device reliability resulting from degradation in the micro-contact region. Therefore, our research focus is to improve the micro-switch reliability by improving micro-contacts with novel contact materials and engineered micro-contact surfaces. The contact metallurgies considered in this work are thin film combinations of Au and Ruthenium. A typical MEMS switch consists of an upper hemispherical bump and a lower planar contact. A micro-switch with engineered micro-contacts will retain the upper hemisperical contact but will replace the lower planar contacts with 2D pyramidal structure. This work suggests that the combination of engineered lower contacts and composite materials can significantly improve the performance and reliability of micro-switches.
Farhana’s MS degree was conferred on the 8th of January, 2020. She has moved on to complete her PhD under Dr. Ronald Coutu’s supervision. Way to go Farhana!
During September 16-18, 2019, Dr. Coutu and Protap Mahanta attended 65th IEEE Holm Conference held in Milwaukee, Wisconsin. Protap Mahanta presented one oral presentation and one poster presentation. Turja Nandy and Mohiuddin Munna volunteered the technical sessions of the conference.
Dr. Coutu presented a work in 28th International Materials Research Congress held in Cancun, Mexico, on 20th August 2019, arranged by Materials Research Society (MRS). Turja Nandy and Dr. Coutu had their poster in the symposium: Materials and Environment.
During June 17-19, 2019, Turja Nandy and Dr. Coutu attended NANOTECH 2019 Conference – TechConnect World Innovation 2019, held in Boston, Massachusetts. Turja Nandy presented two oral presentations and one poster presentation in the symposium: MEMS & NEMS Devices, Modeling & Applications.
