A ceramic is any of the various hard, brittle, heat-resistant and corrosion-resistant materials made by shaping and then firing a nonmetallic mineral, such as clay, at a high temperature. Common examples are earthenware, porcelain, and brick. With such a large range of possible options for the composition/structure of a …

DoD is exploring opportunities to incorporate autonomy, AI, and human-machine teaming into its weapons and operations. Whether as data-mining tools for intelligence analysts, decision aids for planners, or enablers for autonomous vehicle operations, these systems have the potential to provide more accuracy, speed, and agility than traditional tools. Yet operational …

Phase change materials are substances that absorb and release thermal energy (heat) during the process of melting and freezing at defined temperatures . They are called “phase change” materials because they transition from one of the two fundamental states of matter – solid and liquid – to the other during …

As copper reaches its speed limit, engineers look at optics to replace copper for very high speed signals. The electronic transmission of information requires energy – the faster the interface, the more electrical power is required. At very high data transfer rates, optical interfaces can be significantly more efficient than …

The Arctic region encompasses the seas and land north of latitude 66.33° N. The Arctic Ocean is the smallest of the world’s oceans but is transforming due to its melting ice. Eight countries possess territories there: Canada, Denmark (through possession of Greenland), Finland, Iceland, Norway, Russia, Sweden and the US. …
