Transient Directional Solidification of Cast Iron: Microstructure Formation, Columnar to Equiaxed Transition and Hardness [PDF]
Materials Research, 2016 A number of applications may require cast iron. Engine cylinder blocks, flywheels, gearbox cases, machine-tool bases may be manufactured by using grey cast iron while bearing surfaces with white cast iron. Thus, understanding the solidification behaviour

Numerical Simulation of Freckle Defects in Nickel based Superalloys
Journal of Harbin University of Science and Technology, 2020 In order to deeply understand the formation characteristics of freckle defects in the process of directional solidification of nickelbased superalloy, three major equations of fluid mechanics were used to simulate the formation of freckles during the ...

Capillary-wave description of rapid directional solidification [PDF]
Physical Review E, 2012 A recently introduced capillary-wave description of binary-alloy solidification is generalized to include the procedure of directional solidification. For a class of model systems a universal dispersion relation of the unstable eigenmodes of a planar steady-state solidification front is derived, which readjusts previously known stability considerations.

High Temperature Materials and Processes, 2018 Distribution behavior of B and P during directional solidification of Al-20Si, Al-30Si and Al-40Si alloys has been investigated. Macrostructure of the Al-Si alloy ingots and concentration profile of elements B and P reveal that the elements segregate to ...

Directional solidification: Transition from cells to dendrites [PDF]
Physical Review Letters, 1989 The evolution of cells and dendrites on a solidification front is analyzed numerically by a Green's-function method. We obtain a consistent picture of the pattern-forming processes in the whole experimentally accessible range of the phase-diagram cell spacing versus growth rate.

Solidification Front of Oriented Ledeburite
Archives of Foundry Engineering, 2016 Directional solidification of the Fe - 4,3 wt % C alloy was performed with the pulling rate equal to v=83 μm/s. Sample was frozen during solidification to reveal the shape of the solid/liquid interface.

RIPK4 function interferes with melanoma cell adhesion and metastasis
Molecular Oncology, EarlyView.RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Molecular Oncology, EarlyView.Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.
