A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials
Advanced Materials Interfaces, EarlyView.Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...

New results on grain refinement of aluminium are presented by using the efficiency concept, which is a powerful tool to compare the nucleation efficiency of different grain refiners. This involves the calculation of nucleation sites per unit volume, which gives much more information about nucleation than intercept grain size.

Grain formation during solidification of magnesium and Mg-AI alloys has been studied with a focus on grain refinement mechanisms, solute and particle effects. The variation in grain size with increased aluminium content in hypoeutectic Mg-AI alloys showed a continuous decrease in grain size up to 5 wt% Al.

Whole grains, refined grains and fortified refined grains: What’s the difference?
Asia Pacific Journal of Clinical Nutrition, 2000Dietary guidance universally supports the importance of grains in the diet. The United States Department of Agriculture pyramid suggests that Americans consume from six to 11 servings of grains per day, with three of these servings being whole grain products. Whole grain contains the bran, germ and endosperm, while refined grain includes only endosperm.

Mechanism of High Grain Refinement Effectiveness on New Grain Refiner “TiBAl Advance”
2021Grain refiners are used in the aluminum DC casting process to refine the cast structure. On the other hand, high levels of TiB2 particles and other inclusions from the grain refiner can cause clogging of the melt filter. Improvement of the grain refinement effectiveness is required in order to reduce the addition level of grain refiners.

Effect of La on Microstructure and Grain-Refining Performance of Al-Ti-C Grain Refiner
Journal of Rare Earths, 2006Abstract Al-Ti-C grain refiner was prepared by SHS (self-propagating high-temperature synthesis)-melting technique. The effect of La on the microstructures of grain refiner was studied by OM, TEM, SEM, XRD, and EDS. The experimental results indicate that La can improve the wettability between liquid aluminum and graphite; the addition of La results ...

Recently significant successes have been achieved in the field of grain refinement by means of such additives as the titanium, zirconium, scandium, AlTiB and AlTiC. However, introduction of grain refining additives results to a number of negative effects. These effects can be divided into four basic groups: 1.
