A Better Lithium Battery Dr. Stefan Koller with his team at the Institute for Chemistry and Technology of Materials Graz University of Technology has developed a new method to utilize silicon in lithium-ion anode materials. The news stories are saying silicon applied to the anodes raises theoretical storage capacity ten times higher than the graphite substrate, which has been used up to now, and promises considerable improvements for users. Koller, who is familiar with the research in lithium from his doctoral thesis, explains that modern electronic devices need more energy and even the automotive industry is striving for increasingly powerful energy storage systems. The technological development of battery research has been inadequate for some time now. Koller says, “A real revolution is needed for the development of the next generation.
Save 25% on the On-Q/Legrand inQuire Intercom Room Unit through the month of November! You’ll never be more than a few steps away from answering the door, monitoring a child’s room or communicating to another part of the house. On-Q inQuire Intercom Systems not only deliver superior sound, but also install in decorator-style wall plates that blend into the home’s décor. A broadcast system allows talk/page from every unit, and LEDs show stations that are in use, muted or being monitored. Available in white, black, light almond, or ivory, the Broadcast Intercom Room Unit is perfect for any décor. The modern, adjustable backlit keypad makes it simple to communicate in low-light conditions. In addition to paging, the user can monitor other units from anywhere in the house

The National High Magnetic Field Laboratory in Tallahassee Florida has been awarded nearly $3 million to build a novel kind of superconducting magnet that’s expected to break records for magnetic field strength, make possible new types of science and save vast amounts of energy and money. Of interest is the technologies that could benefit from improved magnetic fields such as the Bussard Fusion team. The magnet is funded by a National Science Foundation grant of $2 million and a matching award from The Florida State University of $1 million. The goal is to generate a magnetic field of 32 Tesla, the scientific unit of measure of magnetic field strength. The National High magnetic Field Lab press release says, “That is more than 3,000 times stronger than a typical refrigerator magnet, and about 45 percent more powerful than the strongest superconducting magnets available today.” Brian Wang’s NextBigFuture site offers these applications: Better quantum oscillation measurements Hopefully advanced the understanding of superconductivity physics Should lead to even better superconducting magnets and hopefully breakthroughs in understanding that lead to room temperature superconductors. It will allow more detailed investigation of other superconducting materials It will provide low cost permanent high field magnets instead of pulsing to this field strength or using resistive magnets that are expensive to get up to high field strength

Global warming is one of the “hottest” issues nowadays. The current climate change is the worst yet to happen. Global warming is an overall increase in world temperature which is attributed to the increasing number of greenhouse gases trapped in the atmosphere. Searching an alternative energy source is considered a way of reducing the toxic [...]
