Current opinion in superspreading mechanisms.
Nikolov A, Wasan D. Nikolov A, et al. Adv Colloid Interface Sci. 2015 Aug;222:517-29. doi: 10.1016/j.cis.2014.03.006. Epub 2014 Mar 16. Adv Colloid Interface Sci. 2015. PMID: 24680845 Review.
CONCLUSIONS: A simple model was proposed concerning the surface tension gradient (or Marangoni flow) over the curved droplet surface when the value of the wetting angle was considered. The model predicted the optimum rate of spreading vs. angle at teta = 60 and was …

Structure and stability of nanofluid films wetting solids: An overview.
Nikolov A, Wu P, Wasan D. Nikolov A, et al. Adv Colloid Interface Sci. 2019 Feb;264:1-10. doi: 10.1016/j.cis.2018.12.001. Epub 2018 Dec 7. Adv Colloid Interface Sci. 2019. PMID: 30553993 Review.
We independently verified it by the direct measurement of the nanofilm-meniscus contact angle using reflected light interferometry. Finally, we present some practical applications of a wetting aqueous film for oily soil removal from a solid surface and the nanofilm displac …

Synthetic aperture ultrasound imaging.
Jensen JA, Nikolov SI, Gammelmark KL, Pedersen MH. Jensen JA, et al. Ultrasonics. 2006 Dec 22;44 Suppl 1:e5-15. doi: 10.1016/j.ultras.2006.07.017. Epub 2006 Aug 11. Ultrasonics. 2006. PMID: 16959281 Review.
Data sets for vector flow imaging can be acquired using short imaging sequences, whereby both the correct velocity magnitude and angle can be estimated. A number of examples of both phantom and in vivo SA images will be presented measured by the experimental ultrasound sca …

Capillary Rise: Validity of the Dynamic Contact Angle Models.
Wu P, Nikolov AD, Wasan DT. Wu P, et al. Langmuir. 2017 Aug 15;33(32):7862-7872. doi: 10.1021/acs.langmuir.7b01762. Epub 2017 Aug 1. Langmuir. 2017. PMID: 28722421
The classical Lucas-Washburn-Rideal (LWR) equation, using the equilibrium contact angle, predicts a faster capillary rise process than experiments in many cases. The major contributor to the faster prediction is believed to be the velocity dependent dynamic contact angl …

Oil lenses on the air-water surface and the validity of Neumann's rule.
Nikolov A, Wasan D. Nikolov A, et al. Adv Colloid Interface Sci. 2017 Jun;244:174-183. doi: 10.1016/j.cis.2016.05.003. Epub 2016 May 10. Adv Colloid Interface Sci. 2017. PMID: 27217081 Review.
Here, we highlight an accurate method to study the oil lens's three-phase-contact angle by reflected light interferometry, using both common (CRLI) and differential reflected light interferometry (DRLI) to verify Neumann's rule (the vectorial sum of the three tensions is z …

Nanoparticle self-structuring in a nanofluid film spreading on a solid surface.
Nikolov A, Kondiparty K, Wasan D. Nikolov A, et al. Langmuir. 2010 Jun 1;26(11):7665-70. doi: 10.1021/la100928t. Langmuir. 2010. PMID: 20438106
The complex nature of the interactions between the particles in the nanofluid and with the solid substrate alters the spreading dynamics [Wasan, D. T.; Nikolov, A. D. Nature 2003, 423, 156]. Here, we report, for the first time, the results of an experimental observation of …

Novel approach for calculating the equilibrium foam nanofilm-meniscus contact angle and the film free energy.
Nikolov A, Wu P, Wasan D. Nikolov A, et al. J Colloid Interface Sci. 2019 Dec 1;557:591-597. doi: 10.1016/j.jcis.2019.09.057. Epub 2019 Sep 18. J Colloid Interface Sci. 2019. PMID: 31557579
The film-meniscus transition region, known as the Gibbs-Plateau border, and macroscopic contact angle, defined by the extrapolated meniscus Laplace surfaces, are the characteristics of capillary systems that reveal how the surface forces contribute to the stability of the …
