Two different microstructural architectures featuring multiple length scales have been created in the thermoelectric Mg2(SixSn1 x) system. The first one combines the nano-grain microstructure, characteristic of rapid solidification, with a large-scale pseudo-periodic pattern in one direction. The second is a layered structure in which the composition and microstructural scale vary from layer to...

Periventricular hemorrhagic infarct (PVHI) is among the most devastating injuries suffered by prematurely born infants. In PVHI (formerly called Grade 4 intraventricular hemorrhage), an intraventricular vein that drains smaller veins from the surrounding white matter is occluded, resulting in venous infarction with hemorrhage [1]. DTI has become a useful imaging technique to identify maturation...

Homocysteine level can lead to adverse effects on the brain white matter through endothelial dysfunction, microstructural inflammation, and neurotoxin effects. Despite previously observed associations between elevated homocysteine and macroscopic structural brain changes, it is still unknown whether microstructural associations of homocysteine on brain tissue properties can be observed in healt...

Abstract Heritage buildings always pose challenges due to experiencing high temperatures and pressure over time. Sandstone is one of the common sedimentary rock types used for these buildings. Therefore, it very important understand microstructural variations rocks associated with constructions along mechanical variations. In this study, alteration selected sandstones investigated after heated ...

The extraordinary mechanical performance of spider dragline silk is explained by its highly ordered microstructure and results from the sequences of its constituent proteins. This optimized microstructural organization simultaneously achieves high tensile strength and strain at breaking by taking advantage of weak molecular interactions. However, elucidating how the original design evolved over...
