Confinement Effects in Zeolite‐Confined Noble Metals

Angewandte Chemie International Edition, 2019
AbstractConfinement of noble nanometals in a zeolite matrix is a promising way to special types of catalysts that show significant advantages in size control, site adjustment, and nano‐architecture design. The beauty of zeolite‐confined noble metals lies in their unique confinement effects on a molecular scale, and thus enables spatially confined ...

Confined–unconfined flow in a horizontal confined aquifer

Journal of Hydrology, 2003
Mixed confined and unconfined groundwater flow occurs in a bounded initially dry aquifer when the hydraulic head at the side boundary suddenly rises above the elevation of the aquifer's top boundary. The flow problem as modelled by the Boussinesq equation is non-trivial because of the involvement of two moving boundaries.

SPECTROSCOPY AND CONFINEMENT

International Journal of Modern Physics A, 2003
In this talk I progress semi-historically from the potential model as applied to heavy onia states to the QCD string dynamics of light quark mesons. The virtues and problems of the potential model are reviewed. Some of the difficulties are solved by the introduction of QCD string confinement. The method of solving string models numerically is outlined

Solitary Confinement

2017
Solitary confinement has been used in correctional practice since the very inception of the penitentiary system in the United States. However, by the late 1840’s, it usefulness as a rehabilitative strategy was placed into question. By the late 1880’s, it’s utility as a mode of rationalized retribution quickly became the sole function of this type of ...

What Is Confinement?

2010
Most efforts aimed at proving (or at least understanding) confinement attempt to show that the potential energy between a static quark–antiquark pair (the static quark potential), grows linearly with the separation between the quarks. In other words, since a linear potential is associated with an area-law falloff for Wilson loops, the aim is to show ...
