Tadmor R, Yadav S, Gulec S, Leh A, Dang L, Nguessan H, et al.
Langmuir . 2018 Mar; 34(15):4695-4700. PMID: 29510056
It is shown that introducing gravity in the energy minimization of drops on surfaces results in different expressions when minimized with respect to volume or with respect to contact angle....

Tadmor R, Das R, Gulec S, Liu J, Nguessan H, Shah M, et al.
Langmuir . 2017 Jan; 33(15):3594-3600. PMID: 28121158
We establish a tool for direct measurements of the work needed to separate a liquid from a solid. This method mimics a pendant drop that is subjected to a gravitational...

S Wasnik P, Nguessan H, Tadmor R
J Colloid Interface Sci . 2015 Jun; 455:212-9. PMID: 26072445
In this paper we show a way that allows for the first time to induce arbitrary humidity of desired value for systems without convective flow. To enable this novelty we...

Nguessan H, Leh A, Cox P, Bahadur P, Tadmor R, Patra P, et al.
Nat Commun . 2012 Dec; 3:1242. PMID: 23212371
Classical experiments show that the force required to slide liquid drops on surfaces increases with the resting time of the drop, t(rest), and reaches a plateau typically after several minutes....

Leh A, Nguessan H, Fan J, Bahadur P, Tadmor R, Zhao Y
Langmuir . 2012 Mar; 28(13):5795-801. PMID: 22375701
Viscoelastic braking theories developed by Shanahan and de Gennes and by others predict deformation of a solid surface at the solid-liquid-air contact line. This phenomenon has only been observed for...

Tadmor R, Bahadur P, Leh A, Nguessan H, Jaini R, Dang L
Phys Rev Lett . 2010 Apr; 103(26):266101. PMID: 20366322
A novel instrument allows for the first time measurements of the lateral adhesion forces at a solid-liquid interface, f(parallel), in a way that is decoupled from the normal forces, f(perpendicular)....
