Recently biocomputers are  becoming feasible due to advancements in nanobiotechnology and Synthetic Biology. Biocomputers use systems of biologically derived molecules—such as DNA and proteins—to perform computational calculations. It is expected that the most significant advantage of the DNA chip will be parallel processing.   Scientists are also using  DNA for …

In mathematics, a tensor is an algebraic object that describes a linear mapping from one set of algebraic objects to another. According to Ars Technica, “Basically, a tensor is a matrix of equations, instead of a matrix of pure numbers. Tensor mathematics is the manipulation of these equation matrices as …

Energy harvesting is the process of collecting low-level ambient energy and converting it into electrical energy to be used as a power source for miniaturized autonomous devices. Examples of this can be seen in structural health monitoring, smart packaging solutions, communication systems, transportation, air and aerospace vehicles, structural biology, robotics, …

The vision for the future soldier is to be combat effective and also highly mobile, adaptive, networked, sustainable with total battle space situation awareness and information assurance. Therefore, he is equipped with night- vision goggles, radios, smartphones, GPS, infrared sights, a laptop as well as batteries to power them. Some …

Spintronics is an emerging field of nanoscale electronics  whose central theme is the active manipulation of spin degrees of freedom of charge carriers in solid-state systems, in addition to their electronic charge used in traditional semiconductor electronics. Spintronics or spin electronics in contrast to conventional electronics uses the spin of electrons …

More than thirty countries produce mines, and twenty countries export them. Iran has reportedly laid several thousand naval mines, North Korea’s 50,000, China 100,000 or so, and Russia estimated quarter-million. Since World War II, sea mines have damaged or sunk four times more U.S. Navy ships than all other means …

The threats of chemical, biological, radiological, nuclear and explosive (CBRNE) hazards continue to advance. CBRN weapons are some of the most indiscriminate and deadly weapons in existence today, with capability to affect large population in wide geographical area and in short time. The release of Chemical, Biological, Radiological and Nuclear …

Modern cryptography being used extensively for securing our internet payments, banking transactions, emails and even phone conversations use cryptographic algorithms based on public-key encryption, which is considered to be secure against attacks from modern computers.   The development of quantum computers once seen as a remote theoretical possibility is now …

The warning bells has ringed in US, as  Kim has finally succeeded in developing an ICBM operational capability through which it can deliver a nuclear weapon anywhere in the United States, according to analysis based on Images released by North Korea. North Korea released dozens of photos and a video …

Silicon carbide, also known as carborundum, is a unique compound of carbon and silicon and is one of the hardest available materials.  Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and corrosion, and most importantly, the maintenance of elastic resistance at …
