Permeation and trapping of hydrogen in Eurofer97
Nuclear Materials and Energy, 2021 Diffusion and trapping of hydrogen isotopes in fusion materials need to be fully described in order to evaluate permeation and retention in fusion reactors walls and breeding blankets.

High Voltage, 2022 Needle electrodes are widely used in the research of corona discharge. Aiming at the problem of needle electrode discharge in a large‐scale space (tens or even hundreds of centimetres), a hybrid model was proposed in the previous work.

Effective-range description of a Bose gas under strong one- or two-dimensional confinement [PDF]
New J. Phys. 9 No 1 (January 2007) 19, 2006 We point out that theories describing s-wave collisions of bosonic atoms confined in one- or two-dimensional geometries can be extended to much tighter confinements than previously thought. This is achieved by replacing the scattering length by an energy-dependent scattering length which was already introduced for the calculation of energy levels under

Quantum and Dielectric Confinement Effects in Lower-Dimensional Hybrid Perovskite Semiconductors.
Chemical Reviews, 2019 Hybrid halide perovskites are now superstar materials leading the field of low-cost thin film photovoltaics technologies. Following the surge for more efficient and stable 3D bulk alloys, multilayered halide perovskites and colloidal perovskite ...

Rate effects on layering of a confined linear alkane [PDF]
Phys Rev Lett 99 (2007) 225503, 2007 We perform drainage experiments of a linear alkane fluid (n-hexadecane) down to molecular thicknesses, and focus on the role played by the confinement rate. We show that molecular layering is strongly influenced by the velocity at which the confining walls are approached: under high enough shear rates, the confined medium behaves as a structureless ...

International Journal of Environmental Research and Public Health, 2020 The association between the changes in lifestyle during coronavirus disease 2019 (COVID-19) confinement and body weight have not been studied deeply. Therefore, the aim of the present study was to determine lifestyle changes, such as eating habits and ...

Spatial confinement effects on quantum field theory using nonlinear coherent states approach [PDF]
J.Phys.A42:045403,2009, 2007 We study some basic quantum confinement effects through investigation a deformed harmonic oscillator algebra. We show that spatial confinement effects on a quantum harmonic oscillator can be represented by a deformation function within the framework of nonlinear coherent states theory.

3D confinement of water: H2O exhibits long-range (> 50 nm) structure while D2O does not [PDF]
, 2022 Water is the liquid of life, thanks to its three-dimensional adaptive hydrogen (H)-bond network. Confinement of this network may lead to dramatic structural changes that influence chemical and physical transformations. Although confinement effects occur on a < 1 nm length scale, the upper length scale limit is not known.
