The sample powders (>200 mesh) were first dried at 105 °C for 2 h, then 0.7 g of the dried sample powders was accurately weighted were and placed in a ceramic crucible. The dried sample powders were mixed with 0.4g cosolvent (lithium fluoride) and 0.3 g oxidant (ammonium nitrate), ...
the most to gain from advancing sustainability aspirations. It is no overstatement therefore to assert that rapidly changing African cities, who currently perform poorly against the SDG metrics, are the crucible of SDG implementation. African cities and nations have engaged actively in both structured ...
Approximately 75–100 mg of sample powder and 0.4–0.9 g of tungsten (V) oxide were placed in a porcelain crucible, which was beforehand heated to 1200 °C in a muffle furnace for several hours to remove potential sulfur compounds, and combusted in an oxygen atmosphere at 1350 ...
Typically, 5 g of melamine precursor was finely ground and transferred to a porcelain crucible, then calcined in a tube furnace under a N2 atmosphere at 550 °C for 3 h (with a temperature ramp rate of 5 °C min−1) in order to form bulk g-C3N4. After naturally cooling to room ...
Between 10 and 15 mg of Ivu-1, Ivu-2, Org-2, Org-3, Y-82162 (Y-82a and Y-82b) and Y-980115 were analysed using a TA Instruments SDT Q600 TGA at the Natural History Museum, London, UK. Each sample was loaded into an alumina crucible and analysed under an N2flow of 100 ml ...
The copolymerized polymer (1.03 g) was mixed with a NaOH aqueous solution (1 mol dm−3) in a Teflon crucible and hydrolyzed by heating the solution at 403 K for 12 h. After the solvent was removed, the residual solid polymer was immersed in a HCl aqueous solution (1 ...
rather it is a place of creativity. It is understandable then that the humanness of the scientific process is most apparent here—egos bruised, biases surfaced, clarity threatened—but it is from this crucible that viable theories emerge. It is important not to conflate this aspect of science ...

Firstly, the substrates were buried in a cylindrical alumina crucible, which was full of well-mixed powders, with the diameter of 20 mm and the length of 35 mm. The crucible was sealed with an alumina lid and cement. Then, the packs were loaded into batch-type furnace circulated with...
