As is well known, the remarkable properties of many active crystalline materials, such as shape-memory alloys, originate from a symmetry-breaking martensitic phase transformation. A recent analysis (see [1]) has shown that if a special condition on the strain parameters is satisfied, the twinning ability of a crystal undergoing a cubic-to-monoclinic transformation is considerably increased. As ...

Mg alloys have a vast usage where weight reduction is really significant since they do the features really well for materials of ultra-light weight. However, Mg is inherently a reactive metal and its alloys generally possess quite weak corrosion resistance that widely restricts their technological usages, especially in some rough service conditions. Despite, many investigations on the passive a...

Alloys consisting of the phases α-Mo (Mo solid solution), Mo3Si, and Mo5SiB2 (“T2”) were fabricated by ingot and powder metallurgy. A novel powder-metallurgical processing technique was developed which allows the fabrication of silicide alloys with a continuous α-Mo matrix. In these alloys the relatively ductile and tough α-Mo matrix acts as a “binder” for brittle silicide particles. An alloy p...

BACKGROUND mHealth has experienced a huge growth during the last decade. It has been presented as a new and promising pathway to increase self-management of health and chronic conditions in several populations. One of the most prolific areas of mHealth has been healthy lifestyles promotion. However, few mobile apps have succeeded in engaging people and ensuring sustained use. OBJECTIVE This p...
