R & D talk on Shape Memory alloys & Heat Domes

The R & D Cell (Department of Science & Humanities) of Don Bosco College of Engineering had the session on July 4,  2022. The resource persons were Mr. Harison Cota –  Assistant Professor in Physics and Mr. Milindraj Paigankar – Lab Assistant in Physics.

In his session, Mr. Harison Cota spoke about the Shape Memory alloys.

Shape-memory alloys are metals that, even if they become deformed at below a given temperature, they will return to their original shape before deformation simply by being heated. Mr. Cota demonstrated how the Nitinol alloy works by making use of dental braces. Shape memory alloys with this fascinating property are used as functional materials in temperature sensors, actuators, and clamping fixtures in medical and industrial applications.

Mr. Milindraj Paigankar demonstrated through a video how the Heat Domes occur.

Mr. Milindraj started the session with an explanation about the heat waves and how heat waves lead to more use of Thermal energy and further depletion of the environment due to Greenhouse effect. His main focus was on the occurrence of Heat Domes. A heat dome occurs when the atmosphere traps hot ocean air like a lid or cap. As per National Oceanic and Atmospheric Administration (NOAA), USA, a heat dome is created when strong high-pressure atmospheric condition combine with weather patterns like La Niña. They are more likely to form during La Niña years like 2021, when waters are cool in the eastern Pacific and warm in the western Pacific, creating vast areas of sweltering.

Both the sessions were very educative and well appreciated by Dr. Kala Nayak HOD of Science & Humanities and all the staff. The session was coordinated by Asst Prof. Gladys Da Silva (R&D Coordinator Science & Humanities Department)
