Biography
Imtiaz Ahmad is currently working at the Department of physics, University of Peshawar. His expertise is in condensed Matter Physics. Advanced imaging techniques such as Helium Ion Microscopy (HIM), STM, AFM, HRSEM for the analysis of nanosystems are also his expertise. Self-assembly of nanogeometries and their properties at various wettable surfaces and theoretical interpretation of the forces responsible for shape-separation and self-assembly at the nanoscale is the prime aspect of his work.

Contrast of Ultrasonic Assisted Phase-Separation of RodSphere Mixture with Static Deposits in a Coffee-Stain Rin
Author(s): Imtiaz Ahmad*, Hidayat Ullah Khan and Rahim Jan
The effect of ultrasonic vibrations on the self-assembly and phase separation of nanorods and nanospheres is investigated. Such deposits of rod-sphere mixture on SiO2 surface, dried during ultrasonic vibrations, are compared with static nanoparticle deposits. Phaseseparation at various positions of the coffee-stain ring for both of the cases is evaluated. The ensuing phase separation under ultrasonic agitation is found more noticeable than the one ensemble through static drying. Also, shape separated nanoparticle deposits are studied at various positions of the coffee-stain ring and discuss in relation with steric interaction.
