SXC - Rev. Fr. Franz Goreaux Central Research Facility


The Central Research Facility (CRF) forms an integral part of research activities in the physical sciences and biosciences programmes of the college. It is being upgraded every year in terms of procurement of new advanced level instruments and computational facilities and the total assets now amount to more than Rs.2.0 cr. The centre now plans to extend its infrastructure to other Colleges and Institutions.

Major Objectives:

  • To encourage and facilitate interdisciplinary research among Faculty (both internal and external) in Chemistry, Microbiology, Physics and Biotechnology.
  • To encourage UG/PG students to handle sophisticated instruments and carry out experiments under ‘Skill-based’ module of the CBCS syllabus.

Instrumental Laboratory:

F-7000 Fluorimeter – For carrying out fluorescence and low temperature (77K) phosphorescence studies on –

  • 3-hydroxy naphthoic acid to study the ESIPT process and the effect of added salts at 77K.
  • Fluorescence and phosphorescence studies in certain newly isolated proteins like BTU-F and FHU-D both in their apo and substrate bound conditions like desferal, vit B12.
  • Quenching studies.
  • Interaction of Naproxen (anti-inflamatory drug) with BSA at 77K
  • Energy transfer processes at room temperature – warfarin with Eu3+ and Tb3+.

U-2900 UV/VIS Spectrophotometer:

  • To obtain absorption spectrum of drugs like Naproxen and warfarin.
  • To check the O.D of Proteins like heme binding proteins (hutB) or bacterial enhancer binding protein, FlrA and thereby checking their interaction with the ligands such as heme by seeing the Soret shift at 385nm.

HP Proliant Server:

  • A new reaction path determination method is developed to determine the lowest lying saddle point on a general path connecting the reactant and the product. The search is set up as an optimization problem and solved using the Adaptive Mutation Random Hill Climbing method.
  • Using the real value coded Genetic Algorithm coupled with the nwchem quantum chemistry package for energy determination, we are trying to determine the global minimum structures of small sized (10-20) -doubly charged- water clusters.
  • Measured the effect of gravitational wave on merging binary system near binary black hole.
  • Designed a dynamical model of cosmology based on some recent research works and trying to test the model using standard data.
  • Inclusion of effects of rotation in QMD model of quark.
  • Studying effect of gravitational waves near strong gravitational lenses.
  • We are studying the formation mechanism of Kirkwood gaps in the main asteroid belt in our solar system. First we were trying to understand this in the context of planar circular three body problem. Then we realized that planar elliptical three body problem is more appropriate for this. So, we were simulating directly the equations of motions of Sun-Jupiter and an asteroid (which initially placed at a particular gap). Initially we missed out several parameters of the problem which we have presently sorted out and able to produce similar results like previous authors using a new N-body code.
  • Two students use the desk for theoretical work along with the internet facility. One student works on gravitational collapse and the other student works on cosmological solutions in modified theories of gravity.

Extensive usage of -800C Freezer by scholars for storage of the samples related to research

Crest of SXC

The Crest of St. Xavier’s College is modeled on Jassu Crest of the College Patron Saint Francis Xavier’s family. It has been adapted to local surroundings, suggestive of a native flavour of a College in India. The escutcheon in white and blue contains a tiger and a palm tree, overlooked by a silver crescent moon, which symbolizes the palacio of Xavier. The charge on the Dexter, HIS, bespeaks a College of the Society of Jesus (Iesus Hominum Salvator – Jesus, Savior of Human Family). The checky argent and sable in the base recall the spirit of the Xaverian family. A garter bearing the words “St. Xavier’s College, Calcutta”, encircles the escutcheon and it is surmounted by a Cross emanating holy rays. A scroll passes underneath inscribed with the words Nihil Ultra (Nothing Beyond), the motto of the College. The Crest signifies dignity, courage, quiet gleam and the call of the beyond – the quest persists towards higher endeavour.

St. Francis Xavier Patron of the College

A Christian Minority Higher Educational Institution, St. Xavier’s was founded in 1860 by a Catholic Minority Religious body, the Society of Jesus, and was affiliated to Calcutta University in 1862. While preference is shown to the educational and cultural needs of the Minority community, admission is open to all irrespective of caste, creed and nationality!
