Prof Mohamed Laradji delivers talks at Dept. of Physics

Aligarh : An elected Fellow of the American Physical Society Prof. Mohamed Laradji from the Department of Physics and Materials Science at the University of Memphis, USA visited the Department of Physics and delivered two talks from 15 to 17 May.

In his first talk entitled “Lipid Membranes Mediated Interactions and Self-Assembly of Nano particles”, he emphasized alternative approaches to fabricate nano-assemblies. He discussed that lipid membranes can act as a medium to self-assemble NPs. When NPs adhere to lipid membranes, they induce deformations to the membrane that may extend over length scales well beyond the size of the NPs. He also showed that surface modification of the NPs surface, into Janus NPs, leads to strong repulsive interactions between the NPs, resulting into their self-assembly into a wide range of well-ordered nanoclusters, including three Platonic solids, in the case of NPs adhering to lipid vesicles.

During his second talk on the topic “Collective Motion of Self-Propelled Particles in Circular Confinement and Patterned Substrates”, he explained that the collective motion of self-propelled particles can be investigated through a coarse-grained model of disjoint semi-flexible ring polymers, with a motility force along their polarity that depends on its historical kinetics.

The Chairman of Department of Physics Prof M Sajjad Athar in his introductory note said that Prof Mohamed Laradji work has been focused on theoretical and computational investigations of a variety of problems in soft matter and biological physics, including lipid membranes, polymers, amphiphilic solutions, phase separation dynamics, active matter, nanocomposites, etc. and also holds several US Patents.

On his visit to Maulana Azad Library, he appreciated the rare collections of books, journals and other important documents.
