In 2014, researchers conducted experiments where they exfoliated black phosphorus, or phosphorene, into very thin films of about 10 to 20 atoms thick. Phosphorene, has an inherent bandgap, or energy band in which no electron states can exist, that graphene lacks. According to Philip Feng, an assistant professor of electrical engineering and computer science at Case Western … [Read more...]
New Graphene Based Filament Introduced
Graphene 3D Lab, Inc., has created Black Magic 3D, a commercial graphene-based conductive polymer filament for use in 3D printing to manufacture electronics. “This graphene-enabled polymer filament is unique on the market in its ability to impart electrical conductivity,” IEEE.org said. Black Magic 3D’s volume resistivity measures at 0.6 Ohms-cm. This is 25 times better than … [Read more...]
Scientists Discover Coulomb Interactions Key to Heat Dissipation
An international team of researchers, lead by a team at the University of Michigan, have discovered that Coulomb Interactions dissipate heat better than expected. “The scientists demonstrated that the electrostatic interactions between electrically charged particles — known as Coulomb interactions — in different layers of multi-layered graphene offers a key mechanism for … [Read more...]
New Material Boosts Efficiency of Solar Cells and Improves Cooling
Researchers from Stanford University have successfully improved the efficiency of solar cells and solar panels. They have developed a transparent overlay material, a patterned silica material on top of a normal solar cell, which increases solar cell efficiency by cooling cells in full sunlight. The material works by radiating heat away from the solar cells, according to … [Read more...]
New Headlamp LED
During the ISAL 2015 automotive lighting symposium, Osram Opto Semiconductors introduced a 2,000 lm prototype headlamp LED called the Oslon Black Flat S. Compared with its predecessor, the headlamp LED has enhanced chips and thermal management. “Larger contact pads are partly responsible for better cooling – at 3.75×7.9mm it is slightly larger than its predecessor. When … [Read more...]
