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 …

In recent years, spread of terrorism has assumed an alarming proportion across the globe, because of the simplicity and variety of schemes by which these explosive-based weapons can be deployed causing enormous damage to public safety and environmental pollution. This has emphasized the need for rapid, sensitive and reliable detection …

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. This class of micro- and nano-structured artificial media are predicted to be able to protect …

The inductors along with capacitors and resistors, inductors are one of the three passive elements that are the foundations of all electronics. An inductor works by inducing a magnetic field as an electric current flows through its coil of wire. This magnetic field temporarily stores electric energy as magnetic energy, …

Nanomedicine is a branch of medicine that applies the knowledge and tools of nanotechnology to the prevention and treatment of disease. Nanomedicines typically encapsulate therapeutic and/or imaging compounds in submicrometer-sized carrier materials. Nanomedicine involves the use of nanoscale materials, such as biocompatible nanoparticles and nanorobots, for diagnosis, delivery, sensing or …

Within only a few years, research labs worldwide have adopted a new technology referred to as “CRISPR,”that facilitates making specific changes in the DNA of humans, other animals, and plants. Compared to previous techniques for modifying DNA, this new approach is much faster and easier. CRISPR allows removing a single (defective) …

As computer processors have continued to shrink down to sizes where billions of transistors are on single chip, heat has increasingly become a bigger factor in their performance. If those CPUs did not get as hot in the first place, then much less energy would be needed to keep them …

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 …
