Experimental and analytical study of the motion of a sphere falling along an inclined plane in still water
(Elsevier Science Sa, 2015-08)
In this work, the transient regime of motion of a sphere, that falls along an inclined smooth plane, submerged in still water, is studied experimentally and analytically. Several experiments were performed, with spheres ...
Analysis of tumoral spheres growing in a multichamber microfluidic device
(Veterinary and Human Toxicology, 2018-09)
Lab on a Chip (LOC) farming systems have emerged as a powerful tool for single cell studies combined with a non‐adherent cell culture substrate and single cell capture chips for the study of single cell derived tumor ...
Fractional Laplacians on the sphere, the Minakshisundaram zeta function and semigroups
(American Mathematical Society, 2019)
In this paper we show novel underlying connections between fractional powers of the Laplacian on the unit sphere and functions from analytic number theory and differential geometry, like the Hurwitz zeta function and the ...
Photon spheres in Einstein and Einstein-Gauss-Bonnet theories and circular null geodesics in axially-symmetric spacetimes
(American Physical Society, 2015-09)
In this article we extend a recent theorem proven by Hod [Upper bound on the radii of black-hole photon spheres, Phys. Lett. B 727, 345 (2013)] to n-dimensional Einstein and Einstein-Gauss-Bonnet theories, which gives an ...
Fluids confined in wedges and by edges: Virial series for the line-thermodynamic properties of hard spheres
(American Institute of Physics, 2014-12)
This work is devoted to analyze the relation between the thermodynamic properties of a confined fluid and the shape of its confining vessel. Recently, new insights in this topic were found through the study of cluster ...
Highly microporous monodisperse silica spheres synthesized by the Stöber process
(Elsevier Science, 2014-07)
Silica spheres that are prepared by the Stöber process are usually considered non-porous. Here we report on a slightly modified synthesis protocol that allows preparation of microporous Stöber particles. Successive treatment ...
