Nanoconfined Lanthanum Hydride Nanoconfinement in Functionalized Carbon Hosts
ECS Meeting AbstractsMetal hydrides with a high hydrogen content have long been considered for materials-based hydrogen storage and but are now attracting attention as potential high-temperature superconductors.1 Recently, we showed that cryo-milling lanthanum improves hydrogen diffusion, yielding a higher hydrogen-to-metal ratio of lanthanum hydride up to LaH4.2 ...

Hierarchical thermal transport in nanoconfined water
The Journal of Chemical Physics, 2020The structure of nanoconfined fluids is particularly non-uniform owing to the wall interaction, resulting in the distinctive characteristic of thermal transport compared to bulk fluids. We present the molecular simulations on the thermal transport of water confined in nanochannels with a major investigation of its spatial distribution under the effects

Dielectric properties of nanoconfined water
The Journal of Chemical PhysicsThe dielectric function of a dipolar liquid exhibits a strong wavenumber dependence in the bulk homogeneous state. Such a behavior seems to suggest the possibility of a strong system size dependence of the dielectric constant (DC) of a nanoconfined liquid, although details have been revealed only recently.

Nanoconfinement and the Strength of Biopolymers
Annual Review of Biophysics, 2013This review examines size effects observed in the mechanical strength of biopolymers that are organized in microstructures such as fibrils, layered composites, or particle nanocomposites. We review the most important aspects that connect nanoconfinement of basic material constituents at critical length scales to the mechanical performance of the ...

Dynamics of Nanoconfined Supercooled Liquids
Annual Review of Physical Chemistry, 2011Near their glass transition temperature Tg, supercooled liquids display dramatic changes regarding the dynamics if subject to geometrical restrictions on the scale of 2 to 200 nm. Confinement-induced shifts of Tg of 25 K have been reported, equivalent to relaxation times that differ by several orders of magnitude compared with the bulk liquid at the ...

Temperature Driven Macromolecule Separation by Nanoconfinement
Macromolecules, 2014We focused on the influence of temperature variations on macromolecule partitioning between unconfined and nanoconfined areas in nanoslits using single molecule measurements. We evaluated the number of fluorescent poly(ethylene glycol) (PEG) molecules confined in glass nanoslits in several configurations by fluorescence correlation spectroscopy (FCS ...

Hydrodynamics of Capillary Imbibition under Nanoconfinement
Langmuir, 2012Understanding fluid flow in nanoconfined geometries is crucial for a broad range of scientific problems relevant to the behavior of porous materials in biology, nanotechnology, and the built environment. Because of the dominant importance of surface effects at the nanoscale, long-standing assumptions that are valid for macroscopic systems must be ...

Uniaxial Alignment of Nanoconfined Columnar Mesophases
Nano Letters, 2007By confining discotic phthalocyanines in a network of crisscrossed nanogrooves, we obtain a uniaxial alignment of the columnar mesophase. The alignment process is based on the anisotropy of interface tension between the mesophase and the nanogrooves' walls.

Ultralow Percolation Threshold in Nanoconfined Domains
ACS Nano, 2017Self-assembled percolated networks play an important role in many advanced electronic materials and devices. In nanocarbon composites, decreasing the percolation threshold ϕc is of paramount importance to reduce nanotube bundling, minimize material resources and costs, and enhance charge transport.
