Atomic scale volume and grain boundary diffusion elucidated by in situ STEM
Johann Michler, Xavier Maeder, Laszlo Pethö, Amit Sharma
Diffusion is one of the most important phenomena studied in science ranging from physics to biology and, in abstract form, even in social sciences. In the field of materials science, diffusion in crystalline solids is of particular interest as it plays a p ...
Berlin2023Diffusion timescale conundrum in contact metamorphism: Oxygen isotope and trace element profiles in dolomite
Anders Meibom, Stéphane Laurent Escrig, Lukas Baumgartner, Florence Bégué
Successful application of diffusion chronometry is based on detailed knowledge of diffusion parameters obtained from laboratory experiments, which also need to be upscaled to be applied to natural samples. While generally applicable, several examples of di ...
PERGAMON-ELSEVIER SCIENCE LTD2023Low-Temperature Dynamics of Water Confined in Unidirectional Hydrophilic Zeolite Nanopores
Livia Eleonora Bove Kado, Umbertoluca Ranieri, Maria Rescigno
The dynamical properties of water molecules confinedin the unidirectionalhydrophilic nanopores of AlPO4-54 are investigated withquasi-elastic neutron scattering as a function of temperature downto 118 K. AlPO4-54 has among the largest pores known foralumin ...
AMER CHEMICAL SOC2023Oxygen diffusion through air–water free surfaces in a pump–turbine operating in condenser mode
François Avellan, Elena Vagnoni, Loïc Andolfatto, Pierre Leroy
The present research aims at understanding the mass transfer of air into water in a reversible pump turbine operating in condenser mode. In particular, the diffusion of oxygen through the water free-surface both in the vaneless gap between the impeller bla ...
2019Observation of enhanced ion particle transport in mixed H/D isotope plasmas on JET
Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Jonathan Graves, Yves Martin, Duccio Testa, Patrick Blanchard, Alessandro Pau, Cristian Sommariva, Michele Marin, Henri Weisen, Richard Pitts, Yann Camenen, Jan Horacek, Javier García Hernández, Marco Wischmeier, Nicola Vianello, Mikhail Maslov, Federico Nespoli, Yao Zhou, David Pfefferlé, Davide Galassi, Antonio José Pereira de Figueiredo, Jonathan Marc Philippe Faustin, Liang Yao, Dalziel Joseph Wilson, Hamish William Patten, Samuel Lanthaler, Bernhard Sieglin, Otto Asunta
Particle transport in tokamak plasmas has been intensively studied in the past, particularly in relation to density peaking and the presence of anomalous inward particle convection in L-and H-modes. While in the L-mode case the presence of the anomalous in ...
2018Optimality of integrability estimates for advection–diffusion equations
We discuss Lp integrability estimates for the solution u of the advection–diffusion equation ∂tu+div(bu)=Δu, where the velocity field b∈LtrLxq. We first summarize some classical results proving such estimates for certain ranges of the exponents r and q. Af ...
2017Fast diffusion of water nanodroplets on graphene
Gabriel Aeppli, Gabriele Tocci, Ming Ma
Diffusion across surfaces generally involves motion on a vibrating but otherwise stationary substrate. Here, using molecular dynamics, we show that a layered material such as graphene opens up a new mechanism for surface diffusion whereby adsorbates are ca ...
Nature Publishing Group2016The nature and role of advection in advection-diffusion equations used for modelling bed load transport
Christophe Ancey, Joris Heyman
The advection-diffusion equation arises quite often in the context of sediment transport, e.g., for describing time and space variations in the particle activity (the solid volume of particles in motion per unit streambed area). Stochastic models can also ...
2016Enhanced permeation arising from dual transport pathways in hybrid polymer-MOF membranes
Wendy Lee Queen, Daniel Teav Sun
The rise of anthropogenic global warming has sparked new interest in developing strategies to mitigate carbon dioxide emissions. Conventional carbon capture processes are not economically viable at scale due to their enormous energy cost. Membrane-based se ...
Royal Society of Chemistry2016Stochastic interpretation of the advection diffusion equation and its relevance to bed load transport
Christophe Ancey, Joris Heyman
The advection diffusion equation is one of the most widespread equations in physics. It arises quite often in the context of sediment transport, e.g., for describing time and space variations in the particle activity (the solid volume of particles in motio ...
