Military camouflage has been the subject of continuous improvement and research for over 100 years – ever since the realisation that, supplying troops and equipment with colours matching the ambient environment could lead to improved protection and survivability. A variety of camouflage being developed now is aimed at hiding …

Organic semiconductors enable the fabrication of a range of lightweight and mechanically flexible optoelectronic devices. Organic LEDs, solar cells, and field-effect transistors are now routinely made in bendable or even stretchable formats and with extremely low specific weights. Most organic semiconductor lasers, however, have remained rigid and relatively bulky …

The modern world is filled with macroscopic machines that perform work that we either find demanding or function in places or on length scales in which we cannot act. To date however, we have yet to develop a functional nanotechnology that operates on the scale of molecules or assemblies of …

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 …

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 …
