Understanding superconductivity – whereby certain materials can conduct electricity without any loss of energy – has proved to be one of the most persistent problems in modern physics. Scientists have struggled for decades to develop a cohesive theory of superconductivity...
The U.S. government's auto safety watchdog is investigating whether Tesla's Model S electric car is vulnerable to fires because roadway debris can pierce the car's underbody and battery. The National Highway Traffic Administration, which announced the probe early Tuesday, is looking into two incidents in which Model S drivers struck metal objects on highways.
Batteries that power electric cars have problems. They take a long time to charge. The charge doesn't hold long enough to drive long distances. They don't allow drivers to quickly accelerate. They are big and bulky. Researchers at the University of California, Riverside's Bourns College of Engineering have redesigned the component materials of the battery in an environmentally friendly way....
Solar cells offer the opportunity to harvest abundant, renewable energy. Although the highest energy light occurs in the ultraviolet and visible spectrum, most solar energy is in the infrared. There is a trade-off in harvesting this light, so that solar cells are efficient in the infrared but waste much of the energy...
Researchers have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell phones and other devices. The secret is a stretchy polymer that coats the electrode, binds it together and spontaneously heals tiny cracks...
Researchers from North Carolina State University have developed new technology and techniques for transmitting power wirelessly from a stationary source to a mobile receiver – moving engineers closer to their goal of creating highway “stations” that can recharge electric vehicles wirelessly as the vehicles drive by.

It's about to be a new year at ECN and we're looking forward to the future with a Brainstorm about alternative energy! It's a hot topic in engineering and around the world as researchers, designers, and politicians try to figure out what the energy of the future will be. This month, we're focusing in on SOLAR POWER with a question for our readers
Linear Technology Corporation announces the LT8302, a monolithic flyback regulator that significantly simplifies the design of isolated DC/DC converters. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no opto-isolator or third winding for regulation.
Tiny electrical wires protrude from some bacteria and contribute to rock and dirt formation. Researchers studying the protein that makes up one such wire have determined the protein's structure. The finding is important to such diverse fields as producing energy, recycling Earth's carbon and miniaturizing computers.
A new chapter has been opened in our understanding of the chemical activity of nanoparticles says a team of international scientists. Using the X-ray beams of the European Synchrotron ESRF they showed that the electrons absorbed and released by cerium dioxide nanoparticles during chemical reactions behave in a completely different way than previously thought...
