Heat (i.e., thermal energy) is defined as the energy that is transferred spontaneously between two bodies due to difference in their temperature; heat flows from high to low temperature. There are three main well-known mechanisms for heat transfer: conduction through solid and fluids, convection through fluid, and radiation through solid, …

Trions are what scientists call “quasiparticles,” bundles of energy, electric charge and spin that zoom around inside semiconductors.   Trions were first observed in quantum wells in 1993 and shortly thereafter in GaAs-AlGaAs quantum wells. Trions were were predicted and found in the photoluminescence and absorption spectra of various optically …

Nanotechnology enables designing and creating structures and devices utilising extraordinary properties and behaviour of matter at very fine length scales – nanoscale level (10-9 m). Between 2001 and 2004, approximately 60 countries globally implemented national nanotechnology programmes. According to R.D Shelton, an international technology assessor, research and development in this …

Humans view the intensity of light as the various colors of the spectrum. Characteristics of light include amplitude (intensity), frequency (color), polarization, and coherence. The human eye has cone cells, that correspond reflected light from objects into colors which range from wavelengths of approximately 400-700nm. Polarization, the direction in which …

The Internet of things (IoT) is the network of physical devices, vehicles, home appliances and other items embedded with electronics, software, sensors, actuators, and connectivity which enables these objects to connect and exchange data. Each thing is uniquely identifiable through its embedded computing system but is able to inter-operate within the …

As attack vectors increase with the burgeoning of the Internet of Things (IoT), the Defense sector is exposed to different risks that require increasingly advanced authentication techniques. Today’s threat players are using more sophisticated social engineering tactics, credential-stuffing botnets, and account takeover tactics to pull off all sorts of attacks. …

The DoD has become increasingly reliant on intelligence, surveillance and reconnaissance (ISR) applications. With the advent of expanded ISR capabilities, there is a pressing need to dramatically expand the real-time processing of wide-area, high-resolution video imagery, especially for target recognition and tracking a large number of objects. Not only is …

The emerging field of printed electronics requires a suite of functional materials for applications including flexible and large-area displays, radio frequency identification tags, portable energy harvesting and storage, biomedical and environmental sensor arrays, and logic circuits.   To enable these technologies, functional materials must be integrated with suitable patterning technologies, …

The Defense Advanced Research Projects Agency (DARPA) is soliciting innovative proposals in maritime communications with an emphasis on undersea and cross-domain (above sea to below sea and vice versa) communications. The Defense Advanced Research Projects Agency wants to build an undersea network so that the military can have situational awareness …

Naval Warfare depends a large extent on lethality and survivability of submarines, its principal weapon, therefore Navies have been researching new ways to make them quieter and increasing their underwater endurance. Propulsion system plays an extremely important role in the functioning of a submarine for the completion of its desired …
