At Michigan University USA, Professor Khalil Najafi is working with a doctoral student Erkan Aktakka to find method by which insects can harvest energy from surroundings to run cameras and microphones mounted over them which will help reveal the hazards of the environment they are in and are not safe for human beings. The project aims to build systems that harvest energy at their own and allow them... 

Miniaturization just got a step ahead and scientists have created a very tiny nano scale Electric Vehicle (EV) made up of molecules powered by four motors. It can move in various directions. The vehicle uses electrons to propel. Perhaps that’s the reason it is termed as “electric vehicle” in contrast to previous techniques that used waves etc to move the nano scale vehicles. The car... 

A team of scientists from Oregon State University have managed to store the fast moving light as mechanical excitations. So far, light has been used to transmit data, not store it. But this is something new. Earlier attempts have been made to store light as excitations in the form of sound, spin or atomic form. However in mechanical excitations, the light is stored in silica microspheres. The microspheres... 

At ScientiaWeb, we frequently post articles mentioning developments using Carbon Nanotubes. What are they and what can they yield ? Find out.   Carbon Nanotube is a sheet of graphite, only an atom thick in which carbon atoms are bonded in a hexagonal structure and rolled into a cylindrical tube. They are only 1-100 nanometre in diameter. Currently, they are the strongest known material to man.   Composites... 

MIT Researchers have found a way to improve solar cell efficiency using ‘viruses’ that perform assembly operations at nano level. In this diagram, the M13 virus consists of a strand of DNA (the figure-8 coil on the right) attached to a bundle of proteins called peptides — the virus coat proteins (the corkscrew shapes in the center) which attach to the carbon nanotubes (gray cylinders)... 

Although not the first time, but a better small and super fast single electron transistor has been fabricated by a team of scientists at An atomic-scale depiction of the SketchSET shows three wires (green bars) converging on the central island (center green area), which can house up to two electrons. Electrons tunnel from one wire to another through the island. Conditions on the third wire can result... 

Scientists from University of Buffalo have invented a material for window glass that reflects back heat from sun in summer but allows it during winter. These materials are transparent to infrared light at low temperatures but higher temperature causes them to undergo phase transition (change in internal structure) which improves reflection.   Researchers have basically found the temperature for... 

An atomic force microscope tip scans the surface of a graphene-metal contact to measure temperature upto resolution of about 250 mK. Color represents temperature data. Credit: Alex Jerez, Beckman Institute for Advanced Science and Technology Researchers at University of Illinois have found that graphene based transistors have a cooling effect at nanoscale which lowers their temperature while operation,... 

Team of scientists based in Princess Margaret Hospital have created an organic nanoparticle which is non-toxic, fast and non-degrading. It uses light and heat to treat cancer and deliver drugs to the affected area without any other painful procedure.   Dr. Gang Zheng, the principal investigator from Ontario Cancer Institute, said,”In lab we combined two naturally occurring molecules cholorphyll... 

Engineers at University of Illinois claimed on Friday (11 March, 2011) to have discovered a durable power solution for running gadgets like laptops, mobiles which can run for several months.   Researchers said that they have developed an ultra-low-power digital memory that could extend battery life by as much as 100 times. This is accomplished by using Carbon Nanotubes (A hot area of research)...
