Patenting trends in Single Electron Transistor

Monday, November 15th, 2010

The single electron transistor (SET) is a type of switching device that uses controlled electron tunneling to amplify current. A SET is made from two tunnel junctions that share a common electrode. A tunnel junction consists of two pieces of metal separated by a very thin (~1 nm) insulator. The only way for electrons in one of the metal electrodes to travel to the other electrode is to tunnel through the insulator. Since tunneling is a discrete process, the electric charge that flows through the tunnel junction flows in multiples of e, the charge of a single electron. Applications of SET include nanoelectronics, GSI applications and low power applications. Find out more…

Patenting trends in Edible Packaging

Monday, November 15th, 2010

While edible packaging does reduce the burden on environment and brings down the costs arising out of recycling or reuse, it still has to meet expectations of the consumers in terms of appearance, taste, freshness shelf-life as well as receive regulatory approval. The most widely known applications of edible packaging are food wraps and casings. Find out more…

Pervaporation

Monday, November 15th, 2010

Pervaporation (PVP), a promising separation method, is an energy efficient way of separating liquid mixtures that form azeotropes with components of low relative volatilities and difficult to separate by conventional methods. PVP offers advantages over conventional techniques in terms of being less energy intensive and enabling modular configuration. PVP applications include removal of water from organics or vice versa and separation of organic/organic systems. Find out more…

Patenting trends in Kinetic Energy Harvesting

Monday, November 15th, 2010

Energy generation from alternative sources such as solar, wind, geothermal, biofuel, biomass, tidal wave etc. are associated with high installation and maintenance costs. Kinetic Energy Harvesting (KEH) on the other hand captures minute amounts of energy from sources such as human or animal actions and weight/vibration of moving vehicles for energy generation. This technology uses dynamos, piezoelectric devices, Pressure plates, Springs etc. for energy generation. The technologies associated with KEH are cost-effective, ecofriendly and utilize simple apparatus Find out more …
