A Reversible Nanoconfined Chemical Reaction

ACS Nano, 2010
Hydrogen is recognized as a potential, extremely interesting energy carrier system, which can facilitate efficient utilization of unevenly distributed renewable energy. A major challenge in a future "hydrogen economy" is the development of a safe, compact, robust, and efficient means of hydrogen storage, in particular, for mobile applications.

Interionic Interactions in Conducting Nanoconfinement

ChemPhysChem, 2013
AbstractInterionic interactions in conducting nanopores determine how counterions may be packed in the pores subject to the applied voltage. In ideal metals, interactions are exponentially screened by metallic electrons. However, modern nanoporous electrodes are predominantly made of carbon materials.

Early-Stage Liquid Infiltration in Nanoconfinements

Langmuir, 2023
Liquid infiltration is one of the commonly adapted flow mechanisms in microscale/nanoscale heat-transfer applications. The theoretical modeling of dynamic infiltration profile in the microscale/nanoscale requires a deep study, because the acting forces are entirely different from those of a large-scale system. Herein, a model equation is developed from

Nanoconfined hydrides for energy storage

Nanoscale, 2011
The world in the 21(st) century is facing increasing challenges within the development of more environmentally friendly energy systems, sustainable and 'green chemistry' solutions for a variety of chemical and catalytic processes. Nanomaterials science is expected to contribute strongly by the development of new nanotools, e.g.

Nanoconfined Lanthanum Hydride Nanoconfinement in Functionalized Carbon Hosts

ECS Meeting Abstracts
Metal 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 ...

Nanoconfined Polyelectrolyte Multilayers

Advanced Materials, 2006
Lateral nanometer-scale control over the growth of polyelectrolyte (layer-by-layer) multilayers is demonstrated down to 40 nm, which is well below the natural size of the macromolecules in solution. Because of confinement upon adsorption, the molecules change conformation as compared with the usual, macroscopic case (see Figure). This work opens direct

Dielectric properties of nanoconfined water

The Journal of Chemical Physics
The 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.

Hierarchical thermal transport in nanoconfined water

The Journal of Chemical Physics, 2020
The 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

Dynamics of Nanoconfined Supercooled Liquids

Annual Review of Physical Chemistry, 2011
Near 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 ...

Structure Evolution of Iron (Hydr)oxides under Nanoconfinement and Its Implication for Water Treatment [PDF]

Environmental Science & Technology
In the development of nanoenabled technologies for large-scale water treatment, immobilizing nanosized functional materials into the confined space of suitable substrates is one of the most effective strategies.
