Quenching of lamellar ordering in an n-alkane embedded in nanopores
, 2004 We present an X-ray diffraction study of the normale alkane nonadecane C_{19}H_{40} embedded in nanoporous Vycor glass. The confined molecular crystal accomplishes a close-packed structure by alignment of the rod-like molecules parallel to the pore axis ...

Unravelling friction anisotropy by atomic force microscopy
Journal of Microscopy, Volume 302, Issue 1, Page 111-144, April 2026.Abstract Friction plays a crucial role in both natural phenomena, from the flow of blood cells to earthquakes, and technological applications, from car engines to wind turbines. One of the most fundamental aspects of tribology is friction anisotropy, that is, the dependence of the friction force vector on the direction of sliding.

Theoretical study of C60 as catalyst for dehydrogenation in LiBH4
, 2011 Complex light metal hydrides possess many properties which make them attractive as a storage medium for hydrogen, but typically, catalysts are required to lower the hydrogen desorption temperature and to facilitate hydrogen uptake in the form of a ...

Effect of Functional Group-Modified UiO-66 on the Dehydrogenation of Ammonia Borane
MoleculesAmmonia borane (AB) has attracted much attention in the field of solid-state hydrogen storage due to its high hydrogen storage capacity. Nanoconfinement in UiO-66 can reduce the hydrogen release temperature. In particular, terephthalic acid was used as a

Learning a general model of single phase flow in complex 3D porous media
Machine Learning: Science and TechnologyModeling effective transport properties of 3D porous media, such as permeability, at multiple scales is challenging as a result of the combined complexity of the pore structures and fluid physics—in particular, confinement effects which vary across the ...

Molecular rheology of nanoconfined oligomer melts
Journal of RheologyWe use nonequilibrium atomistic molecular dynamics simulations of unentangled melts of linear and star oligomer chains (C25H52) to study the steady-state viscoelastic response under confinement within nanoscale hematite (α−Fe2O3) channels. We report (i) the negative (positive) first (second) normal stress difference and (ii) the presence of ...
