    Alternating Current Loss of Superconductors Applied to Superconducting Electrical Machines by Hongye Zhang, Zezhao Wen, Francesco Grilli, Konstantinos Gyftakis, Markus Mueller

    Published 2021-04-01
    “…The alternating current (AC) loss of superconductors caused by time-varying transport currents or magnetic fields (or both) has impaired the efficiency and reliability of superconducting machines, bringing severe challenges to the cryogenic systems, too. Although much research has been conducted in terms of the qualitative and quantitative analysis of AC loss and its reduction methods, AC loss remains a crucial problem for the design of highly efficient superconducting machines, especially for those operating at high speeds for future aviation. …”

    The active tectonics of the Vuoksi Fault Zone in the Karelian Isthmus: parameters of paleoearthquakes estimated from bedrock and softsediment deformation features by S.V. Shvarev, A.A. Nikonov, M.V. Rodkin, A.V. Poleshchuk

    Published 2018-12-01
    “…Interpretation of some of these deformation structures can lead to different conclusions about their origin, for example, weathering, cryogenic, glacial, and gravitational factors. One possible way to overcome these difficulties is an integrated study of different types of deformations at key sites, comparison of these with each other and with the tectonic features of the region, and the search for common structural and kinematic features. …”

    Laboratory Evaluation of Mechanical Properties of Modified Asphalt and Mixture Using Graphene Platelets (GnPs) by Mohamed Samir Eisa, Ahmed Mohamady, Mohamed E. Basiouny, Ayman Abdulhamid, Jong R. Kim

    Published 2021-09-01
    “…At the same GnPs content, modified asphalt mixture led to lower failure temperature by 2 °C in comparison with unmodified asphalt mixture and the cryogenic failure stress was improved by 12%. The wheel tracking tests showed that GnPs-modified asphalt mixture has outstanding deformation resistance in comparison with unmodified asphalt mixtures: after 5000 cycles, 1.0 wt% of GnPs reduced the rut depth of asphalt mixture by 60%—the rut depth of unmodified asphalt mixture was 6.9 mm compared to 2.75 mm for modified asphalt mixture. …”

    Ultrafast Investigations of Exciton Dynamics in 0D and 2D Hybrid Semiconductor Nanomaterials by Powers, Eric R.

    Published 2023
    “…A temperature-dependent study of CsPbBr3 nanocrystals reveals that charging occurs in a significant fraction of photoexcited nanocrystals (>10%), which then exhibit a microsecond neutralization lifetime at cryogenic temperatures. The temperature-dependent dynamics are modeled to extract a ~100 meV energy barrier to re-neutralization. …”

    Published 2024
    “…Over the past forty years, membrane-based gas separations have emerged as a promising alternative to energy-intensive separation processes such as amine absorption and cryogenic distillation. However, a trade-off between permeability and selectivity as well as issues of decreased performance at high pressures have hindered widespread membrane deployment. …”

    ORIGIN: metal creation and evolution from the cosmic dawn by Figueroa-Feliciano, Enectali

    Published 2013
    “…The ORIGIN mission includes a Transient Event Detector (coded mask with a sensitivity of 0.4 photon/cm2/s in 10 s in the 5–150 keV band) to identify and localize 2000 GRBs over a five year mission, of which ∼65 GRBs have a redshift >7. The Cryogenic Imaging Spectrometer, with a spectral resolution of 2.5 eV, a field of view of 30 arcmin and large effective area below 1 keV has the sensitivity to study clusters up to a significant fraction of the virial radius and to map the denser parts of the WHIM (factor 30 higher than achievable with current instruments). …”
