A research team at Chalmers is working with carbon nanotubes as conductive material for through-silicon vias. Carbon nanotubes are going to be the most reliable of all conductive materials if it is possible to use them on a large scale. This is the opinion of Kjell Jeppsson, a member of the research team. The researchers have demonstrated that two chips can be vertically … [Read more...]
New Method for Enhancing Thermal Conductivity Could Cool Computer Chips
The surprising discovery of a new way to tune and enhance thermal conductivity gives engineers a new tool for managing thermal effects in smart phones and computers, lasers and a number of other powered devices. The finding was made by a group of engineers headed by Deyu Li, associate professor of mechanical engineering at Vanderbilt University. Li and his collaborators … [Read more...]
Inrush Current Limitation in Power Supplies and Motors
TDK-EPC has extended its range of EPCOS inrush current limiters (ICL). The P11 series (B57211P*) covers a resistance range from 4 to 25 Ω (R25). These types are designed for currents from 2.5 to 5 A in the temperature range between 0 °C and 25 °C. The P13 series (B57213P*) with a resistance range from 3 to 5 Ω is designed for higher powers, i.e. for currents of 6 or … [Read more...]
Dean Receives the Society of Women Engineers’ Highest Honor
Professor Cristina Amon, dean of the University of Toronto’s Faculty of Applied Science & Engineering, has received the 2011 Society of Women Engineers Achievement Award, the highest award given by the Society, for her outstanding contributions to the field of engineering over more than 20 years. Dr. Amon is known for her work in fluid mechanics, heat transfer and … [Read more...]
Researchers Create Cheap Thermoelectric Materials
A team led by Dr Ole Martin Løvvik of Oslo University’s Centre for Materials Science and Nanotechnology in Norway has found a way of making cheap thermoelectric materials that could harvest waste heat from a range of scenarios. However, attempts to bring the technology into the mainstream, in order to harvest waste heat from industrial and everyday scenarios, have been limited … [Read more...]
