Star-shaped droplets

Droplets subject to electric fields may obtain spectacular morphologies. Starting from the seminal works of Rayleigh (1882), Zeleny (1917) and G. I. Taylor (1964), the behaviour of droplets in an electric field continues to fascinate scientists due to their numerous applications. Charged droplets are often generated by electrospray ionization methods. We have found by molecular simulations that when a nano-drop comprising a single spherical central ion and dielectric solvent is charged above a well-defined threshold, it acquires a stable star morphology [S.

Modeling the stability of non-covalent protein complexes and assemblies

Protein-protein interactions (PPIs) play a pivotal role in all biological processes, including signal transduction, enzymatic catalysis as well as the formation of protein quaternary structures.

Manifestations of Charge Induced Instability in Droplets Effected by Charged Macromolecules

Phys. Rev. Lett. 109, 148301 (2012)


Every attempt to employ mathematical methods in the study of chemical questions must be considered profoundly irrational and contrary to the spirit of chemistry.... if mathematical analysis should ever hold a prominent place in chemistry, an aberration which is happily almost impossible, it would occasion a rapid and widespread degeneration of that science.
