Surface Chemistry at the Nanometer Scale [PDF]
, 2011 This thesis describes research towards understanding surface chemical and physical processes, as well as their effects on the underlying substrate properties, at the nanometer and atomic scales. We demonstrate a method to tune the density of etch pits on

Attractive force on atoms due to blackbody radiation [PDF]
, 2017 Objects at finite temperature emit thermal radiation with an outward energy–momentum flow, which exerts an outward radiation pressure. At room temperature, a caesium atom scatters on average less than one of these blackbody radiation photons every 108 ...

α′-corrections to near extremal dyonic strings and weak gravity conjecture
Journal of High Energy Physics, 2022 We construct non-extremal dyonic string solutions in 6D minimal supergravity where the leading higher derivative corrections arise from either the type IIA string theory compactified on K3 or the heterotic string theory compactified on 4-torus.

, 2015 In this paper, we present a detailed study of Skyrmion-Skyrmion scattering for two B=1 Skyrmions in the attractive channel where we observe two different scattering regimes. For large separation, the scattering can be approximated as interacting dipoles.

EVACUACIONES DE EMERGENCIA CON PRESENCIA DE GRUPOS SOCIALES
Anales (Asociación Física Argentina), 2023 In this work we study how the presence of social groups affect emergency evacuations. This investigation was carried out in the context of the Social Force Model (SFM).

Time-dependent attractive force between a silica particle and a silica substrate in dodecane [PDF]
, 2008 Surface forces in low-dielectric media are much less understood than those in aqueous solutions. In this work, the technique of colloidal-probe atomic force microscopy (AFM) was used to measure the force between a silica sphere and a flat silica plate in

The role of attractive forces in viscous liquids [PDF]
The Journal of Chemical Physics, 2011 We present evidence from computer simulation that the slowdown of relaxation of a standard Lennard-Jones glass-forming liquid and that of its reduction to a model with truncated pair potentials without attractive tails are quantitatively and qualitatively different in the viscous regime.

Repulsive black holes and higher-derivatives
Journal of High Energy Physics, 2022 In two-derivative theories of gravity coupled to matter, charged black holes are self-attractive at large distances, with the force vanishing at zero temperature.
