The year 2011-2012 being the International Year of Chemistry, the focus of the department was to broaden the scientific temperament of teachers and students, alike.
The students were encouraged to “think beyond” in the way of assignments as posters, static models and power point presentations as part of their curriculum.
Teachers were encouraged to apprise themselves of the recent advances through submission of Minor and Major research projects, participation in seminars, workshops, paper and poster presentation in national and international reputed journals and Science Meets, and refresher and orientation courses as also clearing the mandatory NET examination.
The students were encouraged to contribute towards Community Service through participation in Mini Marathon organized by the Terry Fox Foundation in aid of Cancer Patients.
