In recent years, high power fiber and semiconductor laser technology has improved rapidly, with power density increasing by an order of magnitude or more. Much of this increase has been driven by demand for industrial cutting machines and high-bandwidth, long-range telecommunications. These same laser materials and devices can also be …

When Hurricane Harvey hit Texas, the Department of Homeland Security (DHS) Science and Technology Directorate (S&T) deployed the Android Team Awareness Kit (ATAK) to support the complex communication and coordination needs of the multi-jurisdictional responders. Most of the operators provided with ATAK in Texas had never used it before. Still, …

Normal solid surfaces are wetted by liquids such as water and oil. In many cases, surface wetting is undesirable due to the fact that the liquids may largely deteriorate the functionality of the surface, or cause unwanted effects. For example, evaporation of liquid droplets could leave behind chemical or dirt …

Quantum key distribution (QKD), establishes highly secure keys between distant parties by using single photons to transmit each bit of the key. A unique aspect of quantum cryptography is that Heisenberg’s uncertainty principle ensures that any attempts to intercept and measure quantum transmissions, will introduce an anomalously high error rate …

Insects are the most successful creatures on the planet, endowed with millions of years of evolution. Attempting robots that mimic the insect form has turned out to be a complex affair. Therefore researchers planned to turn bugs into robots to exploit insects’ natural abilities to achieve feats that are not …

Synthetic biology represents an intersection of biology and engineering that focuses on the modification or creation of novel biological systems. The current state of synthetic biology is mostly the result of research in biology, engineering, computer science, and information technology dating back to the mid-1900s. Synthetic biology has drawn increasing …

Terahertz (THz) waves lie in the electromagnetic spectrum between microwaves and infrared radiation. They are invisible to the human eye. Since they are low in energy, there is no need for be concerned with their impact on human. Today, they play a role in medical and communications technology, but also …
