Jul 07, 2021Geological background. During the early Paleozoic, northwestern Canada formed a promontory along the northern margin of Laurentia. The region was dominated by shallow-water carbonate platforms and deep-water intra-platformal troughs and basins, such as the Richardson trough and Selwyn basin (Fig. 1A) ().These troughs accumulated deep-water strata of the Road River Group

Impact of Ball

Dec 30, 2015Effect of ball-milling pretreatment on pyrolysis characteristics of cellulose was studied by thermogravimetric analysis (TGA) at four different heating rates; 5, 10, 20, and 40 K/min. Variation in the thermal stability and activation energy of cellulose with ball-milling were calculated by TGA Kinetics using Kissinger, Kissinger–Akahira–Sunose, Flynn–Wall–Ozawa and Starink model free

Persistent phosphors for the future: Fit for the right

Dec 24, 2020Therefore, post-synthesis grinding—manually or using a ball mill—is required in that case. Since many phosphor hosts are very hard materials, like oxides, nitrides, and oxynitrides, this particle size reduction is far from obvious and it is a definite advantage to keep the synthesis temperature to a point below the sintering temperature.

Recent Advances in Single

Firstly, the molten salt (ZnCl 2 and NaCl with a mass ratio of 1 : 1), adenine, and Fe 2 O 3 were ground by ball mill. The obtained sample was thermally treated at 900C under inert atmosphere. After removal of the impurities, the single-atom Fe-SAC/NC catalyst was obtained. The strong polarizing force of molten salts plays critical roles in
