Shear Mediated Elongational Flow and Yielding in Soft Glassy Materials
Asima Shaukat, Manish Kaushal, Ashutosh Sharma +1
In this work, we study the deformation behavior of thin films of various soft glassy materials that are simultaneously subjected to two creep flow fields, rotational shear flow by…
Self-organized Nano-lens Arrays by Intensified Dewetting of Electron Beam Modified Polymer Thin-films
Ankur Verma, Ashutosh Sharma
Sub-100 nm polymeric spherical plano-convex nano-lens arrays are fabricated using short electron beam exposures to selectively modify the ultrathin (< 30 nm) polymer films, followe…
Submicrometer Pattern Fabrication by Intensification of Instability in Ultrathin Polymer Films under a Water-Solvent Mix
Ankur Verma, Ashutosh Sharma
Dewetting of ultrathin (< 100 nm) polymer films, by heating above the glass transition, produces droplets of sizes of the order of microns and mean separations between droplets of…
Ultrafast Large Area Micropattern Generation in Non-absorbing Polymer Thin-Films by Pulsed Laser Diffraction
Ankur Verma, Ashutosh Sharma, Giridhar U. Kulkarni
We report an ultrafast, parallel and beyond-the-master micro-patterning technique for ultrathin (30 nm-400 nm) non-absorbing polymer films by diffraction of a laser light through a…
Enhanced Self-organized Dewetting of Ultrathin Polymer Films under Water-organic Solutions: Fabrication of Sub-micron Spherical Lens Arrays
Ankur Verma, Ashutosh Sharma
Field-induced self-organized patterning in ultrathin (< 100 nm) polymer films produces resolutions of the order of 10 μm or more because of the high energy penalty for the surface…
Micro-fabrication of Carbon Structures by Pattern Miniaturization in Resorcinol-Formaldehyde Gel
Chandra S. Sharma, Ankur Verma, Manish M. Kulkarni +2
A simple and novel method to fabricate and miniaturize surface and sub-surface micro-structures and micro-patterns in glassy carbon is proposed and demonstrated. An aqueous resorci…
