Tribological Behaviour of Solid Lubricants in Hydrogen Environment

open access: yesTribology Online, 2011
For further development of hydrogen technology, it is necessary to have a sufficient number of materials for safe and reliable operation available. Frictional contacts exposed to hydrogen, are critical because of vanishing protective oxide layers in the ...

Investigation of Gas Release from Recycled Plastic Shopping Bags during Melting at Low Temperatures [PDF]

open access: yes, 2023
Recycling plastic is an excellent way to reduce the environmental impact of its production and use. In a circular economy, recycling of recycled plastic is necessary. Most plastic bags are made of thermoplastic, like high-density polyethylene (HDPE) with

Regularities of Low-Temperature Deformation and Fracture of Polyimide Films of Kapton H Type of Different Thickness

open access: yesEast European Journal of Physics, 2020
The mechanical characteristics (limit of forced elasticity σforc, fracture stress σfr, relative deformation to failure εfr) of polyimide films of kapton H type under uniaxial tension conditions along the direction of drawing in the temperature range (4.2-

Tropical forcing of Australian extreme low minimum temperatures in September 2019 [PDF]

open access: yes, 2021
We explore the causes and predictability of extreme low minimum temperatures (Tmin) that occurred across northern and eastern Australia in September 2019. Historically, reduced Tmin is related to the occurrence of a positive Indian Ocean Dipole (IOD) and

Low temperature opacities [PDF]

open access: yesInternational Astronomical Union Colloquium, 1994
AbstractThe importance of low temperature opacities in stellar calibrations led us to compute new sets of Rosseland mean opacities for different Z-values. For the solar metallicity, these tables have been compared to those of Alexander (1975), Cox (1983), Sharp (1991) and Kurucz (1992).

Recent Developments in the Field of the Metal-Insulator Transition in Two Dimensions

open access: yesApplied Sciences, 2019
We review the latest developments in the field of the metal-insulator transition in strongly-correlated two-dimensional electron systems. Particular attention is given to recent discoveries of a sliding quantum electron solid and interaction-induced ...

Behaviour of water in jet fuel: a literature review [PDF]

open access: yes, 2013
This review gives a detailed account of the different types of water contaminated fuel and the conditions that bring about each form of contamination. It also considers studies that have been done to date that investigate the physics behind the behaviour
