Experimental and Numerical Simulations of the Solidification Process in Continuous Casting of Slab
Metals, 2016 Thermal simulation equipment (TSE) was recently developed to simulate the solidification process in the industrial continuous casting of slab. The grain growth, solid-liquid interface movement, and columnar-to-equiaxed transition (CET) in the continuous ...

Characterization of metals in four dimensions
Materials Research Letters, 2020 The ability to watch the three-dimensional (3D) evolution of structural materials is a breakthrough in non-destructive characterization. In particular, X-ray tomographic imaging techniques have found success in revealing the underlying mechanisms of ...

Grain charging in protoplanetary discs [PDF]
, 2011 Recent work identified a growth barrier for dust coagulation that originates in the electric repulsion between colliding particles. Depending on its charge state, dust material may have the potential to control key processes towards planet formation such

Grain growth and yield potential of wheat genotypes under late sown heat stressed condition
Fundamental and Applied Agriculture, 2019 Four wheat genotypes (BARI gom 25, BARI gom 26, BAW 1135 and Pavon 76) were sown at different dates (29 November, 5, 16, 23 and 30 December respectively) to evaluate genotypic differences imposed by late seeded heat stress condition.

Effect of High Pressure Spark Plasma Sintering on the Densification of a Nb-Doped TiO2 Nanopowder
Ceramics, 2020 Sintering under pressure by means of the spark plasma sintering (SPS) technique is a common route to reduce the sintering temperature and to achieve ceramics with a fine-grained microstructure.
