The Influence of Host Star Spectral Type on Ultra-Hot Jupiter Atmospheres [PDF]

open access: yes, 2019
Ultra-hot Jupiters are the most highly irradiated gas giant planets, with equilibrium temperatures from 2000 to over 4000 K. Ultra-hot Jupiters are amenable to characterization due to their high temperatures, inflated radii, and short periods, but their ...

Novel thin film polymer foaming technique for low and ultra low-k dielectrics [PDF]

open access: yes, 2001
The results presented show a novel route for the preparation of thin ultra-low-k polymer films based on commercial and "non-exotic" (non-expensive) polyimide by a foaming technique.

Thermometry at Ultra-Low Temperatures [PDF]

open access: yesJapanese Journal of Applied Physics, 1987
A new millikelvin temperature scale is presented which is based in part on the constraint that the normal-phase specific heat of liquid 3He be linear in temperature with a proportionality constant taken from higher-temperature specific heat measurements.

Unifying the low-temperature photoluminescence spectra of carbon nanotubes: the role of acoustic phonon confinement [PDF]

open access: yes, 2014
At low temperature the photoluminescence of single-wall carbon nanotubes show a large variety of spectral profiles ranging from ultra narrow lines in suspended nanotubes to broad and asymmetrical line-shapes that puzzle the current interpretation in ...

Ultra-low-temperature aqueous batteries [PDF]

open access: yesScience, 2019
Energy Storage The development of efficient electrochemical energy storage systems is of prime importance for future energy management, which will be increasingly based on renewable energy sources. Aqueous rechargeable alkali-ion batteries are particularly attractive for large-scale implementations given their environmentally friendly components and ...

Angle-resolved Photoemission Spectroscopy At Ultra-low Temperatures [PDF]

open access: yesJournal of Visualized Experiments, 2012
The physical properties of a material are defined by its electronic structure. Electrons in solids are characterized by energy (ω) and momentum (k) and the probability to find them in a particular state with given ω and k is described by the spectral function A(k, ω).

Ultra-Low-Temperature Refrigeration Systems: A Review and Performance Comparison of Refrigerants and Configurations

open access: yesEnergies, 2023
During the last decade, many industrial and medical applications have shown a requirement for low-temperature-cooling usage (from −40 to −80 °C), which cannot be efficiently obtained via the conventional refrigeration systems usually employed for medium ...

High Temperature Oxidation of Ultra-Low-Carbon Steel [PDF]

open access: yesDefect and Diffusion Forum, 2006
An oxide scale layer always forms at the strip surface during the hot rolling process. Its properties have a large impact on surface quality. The most important features of the oxide layer are its thickness, composition, structure, adherence and coherence. Temperature, time and gas atmosphere determine the growth of oxide layers.

RELaTED Project: New Developments on Ultra-Low Temperature District Heating Networks

open access: yesProceedings, 2020
District heating networks deliver around 13% of the heating energy in the EU, being considered as a key element of the progressive decarbonization of Europe. The H2020 REnewable Low TEmperature District project (RELaTED) seeks to contribute to the energy
