Power and Electrical Engineering

Electrochemical transistors made of plastic open myriad possibilities. Since both electrons and ions are active, they can function as a bridge between traditional electronics and biological systems. A new dissertation from Linköping University in Sweden describes a simple and inexpensive humidity sensor that can be manufactured in a printing press.

Electrically conducting plastic is used today in field effect transistors, light-emitting diodes, electrochemical components, and

A new study has disclosed perhaps the strongest evidence to date for superfluidity in an exotic gas that mimics extreme behavior in Nature — ranging from high temperature superconductivity to the behavior of fundamental particles in the Big Bang, when the universe is believed to have begun in a huge burst of energy within a very small space. Although the gas was trapped by a laser beam within billionths of a degree of absolute zero, the lowest possible temperature, researchers said it behaved

Significant advances in university research and other studies in the past two years are pointing toward Oregon as the possible epicenter of wave energy development in the United States.

This may lead to a major initiative to expand a technology that is now in its engineering infancy, and tap the constant heave of the oceans for a new era of clean, affordable and renewable electrical power. Electrical engineers at Oregon State University have pioneered the development of techno

Thieves could exploit encryption vulnerabilities, computer scientists warn

A popular radio-frequency ID system that is used to deter car thefts and as a convenience device for the purchase of gasoline can be defeated with low-cost technology, computer scientists from The Johns Hopkins University and RSA Laboratories have determined.
Their findings, described in a new research paper, indicate that the encryption in RFID microchips in some newer car keys and wireless payment tag

NETL and Carnegie Mellon develop new computational modeling tool

The Department of Energy’s National Energy Technology Laboratory (NETL) and Carnegie Mellon University have developed a new computational modeling tool that could make the production of hydrogen cheaper as the United States seeks to expand its portfolio of alternative energy supplies.

The research, supported by the DOE’s Office of Fossil Energy and reported in the current issue of the prestigious journ

The storage of hydrogen in fuel cell powered cars can probably be greatly improved by increasing the working temperature of the fuel cell. With the use of magnesium powder, the storage of hydrogen can take place more efficiently and safely and at a higher temperature. This is the conclusion of Gijs Schimmel, who will defend his PhD thesis at TU Delft on 1 February.

One of the main problems in the transition to a hydrogen economy is the storage of hydrogen, for use in vehicles, for
