Abstract: The graphite-MoS2 coated on GCr15 bearing steel is prepared through air spraying and its tribological performances are investigated experimentally. Then its coefficient of friction (COF) and wear scar width (WSW) are ...

Abstract: The winter climate of the British Isles is characterized by considerable interannual variability, which, because of the general climate sensitivity of a number of health outcomes, places at times considerable pressure on ...

Abstract: easured ice crystal concentrations in natural clouds at modest supercooling (temperature ~>?10°C) are often orders of magnitude greater than the number concentration of primary ice nucleating particles. Therefore, it has ...
