The Journal of Physical Chemistry B, 2011 In the diffusion model of chemical reactions, the encounter (reaction) rate between reactant particles is governed by the Smoluchowski equation, which is a diffusion equation in a field of forces. We consider crowded environments where the particles diffuse through a "liquid" of like particles. Assuming that the liquid-like short-range structure around

Brief communication: An autonomous UAV for catchment-wide monitoring of a debris flow torrent [PDF]
Natural Hazards and Earth System Sciences, 2022 Debris flows threaten communities in mountain regions worldwide. Combining modern photogrammetric processing with autonomous unoccupied aerial vehicle (UAV) flights at sub-weekly intervals allows mapping of sediment dynamics in a debris flow catchment ...

Lattice Boltzmann Simulation of Multicomponent Porous Media Flows With Chemical Reaction
Frontiers in Physics, 2021 Flows with chemical reactions in porous media are fundamental phenomena encountered in many natural, industrial, and scientific areas. For such flows, most existing studies use continuum assumptions and focus on volume-averaged properties on macroscopic ...

Spatial and Temporal Oscillations of Surface Tension Induced by an A + B → C Traveling Front
Frontiers in Physics, 2022 This work describes a new mechanism for the emergence of oscillatory dynamics driven by the interaction of hydrodynamic flows and reaction-diffusion processes with no autocatalytic feedback nor prescribed hydrodynamic instability involved.

Global financial crisis and its impact on global trade trends and WTO [PDF]
Međunarodni Problemi, 2014 The modern economic and financial crisis has caused a significant reduction in trade flows for the first time since the Second World War, so it is often referred to as the trade crisis.
