Effects of Hyporheic Exchange and Settlement on the Particle Size Distribution of Colloids
David Andrew Barry, Qihao Jiang
Colloid particle size plays an important role in contaminant adsorption and clogging in the hyporheic zone, but it remains unclear how the particle size changes during the transport of colloids. This study investigated the variation of the particle size of ...
New York2024Influence of Ventilation on Formation and Growth of 1-20 nm Particles via Ozone-Human Chemistry
Dusan Licina, Shen Yang, Marouane Merizak, Meixia Zhang
Ozone reaction with human surfaces is an important source of ultrafine particles indoors. However, 1-20 nm particles generated from ozone-human chemistry, which mark the first step of particle formation and growth, remain understudied. Ventilation and indo ...
Washington2024A Method of Moments Estimator for Interacting Particle Systems and their Mean Field Limit
Andrea Zanoni, Grigorios A. Pavliotis
We study the problem of learning unknown parameters in stochastic interacting particle systems with polynomial drift, interaction, and diffusion functions from the path of one single particle in the system. Our estimator is obtained by solving a linear sys ...
Siam Publications2024Modeling friction and wear using an adaptive discrete-continuum coupling
Manon Eugénie Voisin--Leprince
When two objects slide against each other, wear and friction occur at their interface. The accumulation of wear forms what is commonly referred to as a ``third-body''. Understanding third-body evolution has significant applications in industry, where contr ...
EPFL2024Chiral Anomaly and Dynamos from Inhomogeneous Chemical Potential Fluctuations
In the standard model of particle physics, the chiral anomaly can occur in relativistic plasmas and plays a role in the early Universe, protoneutron stars, heavy-ion collisions, and quantum materials. It gives rise to a magnetic instability if the number d ...
Amer Physical Soc2024Highly anisotropic carbon fiber electrodes for DEAs and their dynamic non-monotonic conductive properties
Yves Perriard, Stefania Maria Aliki Konstantinidi, Markus Koenigsdorff
A common method for creating compliant electrodes for dielectric elastomer actuators (DEAs) and soft sensors is to incorporate electrically conductive carbon particles into a polymer matrix. However, using unidirectional aligned carbon fibers instead not o ...
Society of Photo-Optical Instrumentation Engineers (SPIE)2024Second harmonic scattering of nanoparticles: A journey into the electrical double layer
In aqueous solutions, a charged surface causes the redistribution of nearby ions. The ion layers formed are known as the electrical double layer (EDL), and are widespread in many systems involving electrochemistry, colloidal science, biomedicine, and energ ...
EPFL2024Inhalation of Microplastics—A Toxicological Complexity
Florian Frédéric Vincent Breider, Myriam Borgatta
Humans are chronically exposed to airborne microplastics (MPs) by inhalation. Various types of polymer particles have been detected in lung samples, which could pose a threat to human health. Inhalation toxicological studies are crucial for assessing the e ...
2024Nonempirical semilocal density functionals for correcting the self-interaction of polaronic states
Alfredo Pasquarello, Stefano Falletta
Through the use of the piecewise-linearity condition of the total energy, we correct the self-interaction for the study of polarons by constructing nonempirical functionals at the semilocal level of theory. We consider two functionals, the gamma DFT and mu ...
Aip Publishing2024Energy-Efficient Particle Accelerators for Research
Particle accelerators are the drivers for large-scale research infrastructures for particle physics but also for many branches of condensed matter research. The types of accelerator-driven research infrastructures include particle colliders, neutron, muon ...
