Tunable Nanowrinkles on Shape Memory Polymer Sheets
Chi-Cheng Fu,Anthony Grimes,Maureen Long,Christopher G. L. Ferri,Brent D. Rich,Somnath Ghosh,Sayantani Ghosh,Luke P. Lee,Ajay Gopinathan,Michelle Khine +9 more
TL;DR: In this paper, a simple two-step approach is used to fabricate controllable biaxial and uniaxially nanowrinkles based on shape memory polymer (prestressed polystyrene) sheets.
Journal ArticleDOI
ZnO/Ag nanohybrid: synthesis, characterization, synergistic antibacterial activity and its mechanism
TL;DR: In this article, a highly homogeneous ZnO/Ag nanohybrid has been synthesized by a novel route, employing chitosan as mediator by purely electrostatic interaction.
Journal ArticleDOI
Antimicrobial activity of highly stable silver nanoparticles embedded in agar-agar matrix as a thin film.
Somnath Ghosh,Rajni Kaushik,K. Nagalakshmi,S.L. Hoti,Godfred A. Menezes,Belgode Narasimha Harish,H. N. Vasan +6 more
TL;DR: Highly stable silver nanoparticles in agar-agar (Ag/agar) as inorganic-organic hybrid were obtained as free-standing film by in situ reduction of silver nitrate by ethanol and the mechanical strength of the film determined by nanoindentation technique showed almost retention of the strength even after repeated cycle.
Journal ArticleDOI
Trapping of drops by wetting defects
Dieter 't Mannetje,Somnath Ghosh,R. Lagraauw,Simon Otten,Arjen Pit,C.W.J. Berendsen,Jos C.H. Zeegers,Dirk van den Ende,Frieder Mugele +8 more
TL;DR: The general physical conditions required for capturing sliding drops on an inclined plane that is equipped with electrically tunable wetting defects are determined and it is shown that electrically Tunable defects can be used to guide sliding drops along actively switchable tracks—with potential applications in microfluidics.
Journal ArticleDOI
Localization and adiabatic pumping in a generalized Aubry-André-Harper model
TL;DR: In this paper, a generalized version of the AAH model is developed, containing a tunable phase shift between on-site and off-diagonal modulations, which can be induced by varying just this phase, keeping all other model parameters constant.
