Chemical reactivity under nanoconfinement
Nature Nanotechnology, 2020Confining molecules can fundamentally change their chemical and physical properties. Confinement effects are considered instrumental at various stages of the origins of life, and life continues to rely on layers of compartmentalization to maintain an out-of-equilibrium state and efficiently synthesize complex biomolecules under mild conditions.

Chemical Reviews, 2016
Ionic liquids (ILs) have been widely investigated as novel solvents, electrolytes, and soft functional materials. Nevertheless, the widespread applications of ILs in most cases have been hampered by their liquid state. The confinement of ILs into nanoporous hosts is a simple but versatile strategy to overcome this problem. Nanoconfined ILs constitute a

Superpermittivity of nanoconfined water
The Journal of Chemical Physics, 2015Nowadays, it is well established that the physical properties of confined liquids strongly differ from those in bulk phase. While dynamical and structural properties were strongly explored, dielectric properties are poorly studied despite their importance in the understanding and the modelling of molecular mechanism in a number of nano-applications ...

Nanoconfined Polyelectrolyte Multilayers
Advanced Materials, 2006Lateral 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

Viscous Water Meniscus under Nanoconfinement
Physical Review Letters, 2006A dramatic transition in the mechanical properties of water is observed at the nanometer scale. For a water meniscus formed between two hydrophilic surfaces in the attractive region, with < or = 1 nm interfacial separation, the measured viscosity is 7 orders of magnitude greater than that of bulk water at room temperature.

Early-Stage Liquid Infiltration in Nanoconfinements
Langmuir, 2023Liquid 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, 2011The 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.

Interionic Interactions in Conducting Nanoconfinement
ChemPhysChem, 2013AbstractInterionic 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.

Nanoconfined crystallites toughen artificial silk
Journal of Materials Chemistry B, 2014Spider dragline silk is of great interest to people for its outstanding mechanical properties including high toughness. Biomimetic spinning of spider silk has attracted people's attention for decades. This paper reports a simple and cheap method to greatly toughen artificial silk by compositing with nanoanatase.

A Reversible Nanoconfined Chemical Reaction
ACS Nano, 2010Hydrogen 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.
