Many Military and Aerospace missions  are  going beyond the  classical mechanics through pursuit of higher, farther, deeper, faster, smarter, safer, healthier, and cleaner goals in material production, such as aerostats up to tens of kilometers in length, interstellar travel as far as several light-years, deep-sea submersibles that dive as deep …

Metamaterials are artificially structured materials designed to control and manipulate physical phenomena such as light and other electromagnetic waves, sound waves and seismic waves in unconventional ways, resulting in exotic behavior that’s not found in nature. They are predicted to be able to protect the building from earthquakes by bending …

Gallium nitride (GaN) is hot. Even hotter is a race to integrate GaN with other materials to boost GaN’s performance further.   The power electronics industry has seen the theoretical performance limit reached by silicon MOSFETs and now needs to move to a new element. GaN is a wide bandgap, …

Understanding the complex and increasingly data-intensive world around us relies on the construction of robust empirical models, i.e., representations of real, complex systems that enable decision makers to predict behaviors and answer “what-if” questions. Empirical models lie at the heart of much science (e.g., quantitative physics, material science, chemistry, biology/medicine, …

Nanomaterials (NMs) have gained prominence in technological advancements due to their tunable physical, chemical and biological properties with enhanced performance over their bulk counterparts. NMs are categorized depending on their size, composition, shape, and origin. Newly discovered materials such as fullerene, carbon nanotubes (CNTs), graphene, transition metal dichalcogenides, hexagonal boron nitride …

UUVs—submersible unmanned vehicles—are divided into two categories: remotely operated underwater vehicles (ROVs) and autonomous underwater vehicles (AUVs). ROVs are controlled and powered by a person or crew on either land or neighboring craft via an umbilical or using remote control. The truly autonomous AUV systems are typically deployed from a …

3D printing or additive manufacturing is ongoing revolution in manufacturing with its potential to fabricate any complex object and is being utilized from aerospace components to human organs, textiles, metals, buildings and even food.  Its advantages include less waste and an ability to print custom designs, such as intricate lattice …

Photonics, the science of generating, detecting and manipulating particles of light, forms the basis of many of the technologies we use in our everyday life. In the evolving branch of integrated photonics, increasingly large and complex optical circuits can be built on the surface of a chip. The majority of …

Our society’s infrastructure is increasingly dependent on software deployed on a wide variety of computing devices other than commodity personal computers, such as industrial equipment, automobiles, and airplanes. Unlike commodity computers that have short upgrade cycles and are easily replaceable in case of failure, these computing devices are intended for …

All kinds of engineering infrastructures undergo aging, and damage appears as a consequence of the loads applied to them, so inspection and maintenance actions are required to predict and lengthen their lifetime thus avoiding catastrophic failures. Due to the harsh conditions suffered by aircraft structures, periodic and scheduled inspection and …
