Press coverage of Prof. K. Chattopadhyay Group’s research on mechanical behaviour of sea shells

We are pleased to note that several popular science media outlets have covered a recent paper from Prof. Chattopadhyay’s group in the journal Scientific Advances: Morphogenesis and mechanostabilization of complex natural and 3D printed shapes (by Chandra Sekhar Tiwary, Sharan Kishore, Suman Sarkar, Debiprosad Roy Mahapatra, Pulickel M. Ajayan, Kamanio Chattopadhyay).

Here’s a partial list:

Professor Philip Eisenlohr from Michigan State University is visiting our department as an Aaronson Visiting Scientist.

Professor Philip Eisenlohr from Michigan State University is visiting our department as an Aaronson Visiting Scientist. His current research interests include mechanical behavior of materials and computational materials science.

He will be here till 29th June and sitting in Professor Rangnathan’s office (A-208). Besides interacting with interested faculty members and students, he will also be delivering a seminar on computational materials science and a series of lectures on computational crystal plasticity. Soon we will announce the schedule for the seminar and the lectures.

RIP: Prof. G.N.K. Iyengar

It is with deep regret and sadness that we announce the passing away of Prof. G.N.K.Iyengar, an alumnus and former faculty member of our department, on Friday, 17th April, 2015 at 6.30 p.m. at his residence.

A condolence meeting is being arranged on 22.04.2015 (wednesday) at 11.30 a.m. in the Lecture Theatre of the department.

If you wish to share your tributes to (and reminiscences of your association with) Prof. Iyengar, please send them to Prof. S. Subramanian at

Postdoctoral/Research Associate position in Multiphase Flow Modelling at IISc
in Department of Materials Engineering

Date of posting vacancy: April 1, 2015

Deadline: April 16, 2015

Duration: 3 years

Job Description:

Brief outline of the job to be carried out under this project:
* Modifying the existing turbulent fluid and fines flow models/codes and
developing & modifying the existing DEM model/code for particle and combining
them with the existing liquid flow model/code. Developing heat and mass
transfer model/code for a packed bed under the above mentioned conditions and
combining it with above mentioned computer codes.
* May develop a cluster and parallelize the computer codes.
* Assisting/performing experiments to validate the findings.
* May assist in supervising postgraduate students.


Ph.D. in Chemical, Metallurgy, Mechanical, Aerospace, Civil, Physics and
related areas. A good working experience in the field of Computational Fluid
Dynamics including a sound knowledge of numerical techniques with strong
programming skill in FORTRAN / C is essential. Knowledge of Discrete Element
Method (DEM) including coupling of Eulerian-Lagrangian based models would be
desirable but not essential. Experience in multiphase flow modeling including
heat and mass transfer in a moving bed would be advantageous.

Other information:

Consolidated salary would be Indian Rupees (INR) 52,000.00 per month. The
initial appointment would be for one year extendable up to three years
depending upon the satisfactory performance of the candidate. Interested
candidates are requested to send their CV and one or two best publications
along with the contact details of three references to:,

UG Final Year Project: Oral Examination

The Oral Exam for the UG Final Year Project will take place in the last week of April. Here’s the broad description of the process we will follow this year:

1. All the students are to submit three copies of their Project Report to Mrs. Lakshmi in the office of the Department of Materials Engineering. The deadline for submission is 5:00 p.m. on Monday, the 20th of April.

The Report needs to be submitted either in a spiral-bound form, or in a file. After incorporating all the corrections and suggestions from the examiners, the final, bound version of the Report has to be submitted on the 30th of April.

2. The Oral Examination board will consist of two common examiners, the Project guide(s), and an examiner identified by the guide(s).

3. The time-table for the Oral Exam will be sent in due course.

Please contact Prof. Abinandanan if you need any further information.

An article in The Hindu on Prof. Suryasarathi Bose’s research

R. Prasad in The Hindu: IISc researchers produce a superior water filter:

A membrane capable of producing safe drinking water by filtering out objects at the nanoscale level and killing the commonly found pathogenic bacteria E. coli has been developed by a team led by Dr. Suryasarathi Bose, Assistant Professor, Department of Materials Engineering, IISc, Bengaluru.

The membrane is produced by mixing two polymers — poly(vinylidene fluoride) (PVDF) and poly(methyl methacrylate) (PMMA) — that become miscible at about 220 degree C. While PVDF crystallises during cooling, PMMA does not and separates out; the PMMA is removed using a solvent. This property of selective crystallisation and separation is taken advantage of to produce a nano-porous membrane.
