Metrics for the emissions of F-gas refrigerants by Miranda, ND, Palafox-Alcantar, PG, Khosla, R, McCulloch, M

“…Second, we use an atmospheric model to illustrate how the incumbent metric (CO2-equivalent calculated using GWP100), misrepresent the warming of an exemplary f-gas refrigerant (HFC-134a). The model outputs novel profiles of atmospheric concentration, radiative forcing, and temperature, in three scenarios. …”

Development of a sorption-cooled continuous miniature dilution refrigerator for 100 mK detector testing by May, A, Azzoni, S, Banys, D, Coppi, G, Haynes, V, McCulloch, MA, Melhuish, SJ, Piccirillo, L, Wenninger, J

“…This has strongly driven the development of several related systems, including the continuous miniature dilution refrigerator (MDR) reported here. The MDR is comprised of a thermally separated mixing chamber, step heat exchangers, twin stills and twin condensation pumps. …”

China's compliance with the Montreal Protocol by Zhao, J, Ortolano, L

“…An analysis of the household refrigeration sector and the foams sector investigates how Chinese enterprises have complied with the Montreal Protocol on Substances That Deplete the Ozone Layer. …”

Impact of solar panels and cooling devices on frequency control after a generation loss incident by Peruffo, A, Guiu, E, Panciatici, P, Abate, A

“…Common household devices, such as solar panels and refrigerators, offer a considerable potential for frequency regulation, given their aggregate power generation and consumption. …”

OPTICAL SPECTROSCOPY OF GAAS IN THE EXTREME QUANTUM LIMIT - INTEGER AND FRACTIONAL QUANTUM HALL-EFFECT, AND ONSET OF THE ELECTRON SOLID by Clark, R, Ford, R, Haynes, S, Ryan, J, Turberfield, A, Wright, P, Williams, F, Deville, G, Glattli, D, Mallett, J, Vanderburgt, M, Oswald, P, Herlach, F, Foxon, C, Harris, J

“…Our recent optical detection of the integer and fractional quantum Hall effects in GaAs, by intrinsic band-gap photoluminescence at dilution refrigerator temperatures, is reviewed. This work has been extended to the extreme quantum limit where a photoluminescence peak develops close to Landau level filling factor ν = 1/5 which correlates both with the onset of threshold behaviour in current-voltage characteristics of the two-dimensional electron system and a resonant radio-frequency absorption; the latter are quantitatively accounted for by a model of crystalline electronic structure broken up into domains. …”

THE CONSTRUCTION AND PERFORMANCE OF BSCCO-2212 COILS FOR USE IN LIQUID-NITROGEN AT 64K ON AN IRON YOKE IN DEMONSTRATOR DEVICES by Jenkins, R, Jones, H, Yang, M, Goringe, M, Grovenor, C

“…A ''demonstrator'' device is described in which the coils are mounted on an iron yoke, are immersed in liquid nitrogen refrigerated to 64K using a novel technique, and provide ampere-turns to generate a magnetic field in the airgap between two room temperature pole-pieces. …”

POLAREX - Study of polarized exotic nuclei at millikelvin temperatures by Risegari, L, Astier, A, Audi, G, Cabaret, S, Gaulard, C, Georgiev, G, Stone, N, Stone, JR

“…A radioactive beam of interest is implanted into a ferromagnetic host foil held at a temperature of order 10mK in a 3He-4He dilution refrigerator. The foil is magnetized by an applied magnetic field and the nuclear spins become polarized through the internal hyperfine field. …”
