Substrate defects key to growth of 2-D materials

Creating two-dimentional materials large enough to use in electronics is a challenge despite huge effort but now, Penn State researchers have discovered a method for improving the quality of one class of 2-D materials, with ...

Smart pill bottle keeps drugs safe

Low-cost, stretchy sensors can be assembled inside the lid of a drug container to help monitor patient safety.

Flexible circuits for 3-D printing

A research collaborative between the University of Hamburg and DESY has developed a process suitable for 3-D printing that can be used to produce transparent and mechanically flexible electronic circuits. The electronics ...

A new energy-saving LED phosphor

The human eye is particularly sensitive to green, but less sensitive to blue and red. Chemists led by Hubert Huppertz at the University of Innsbruck have now developed a new red phosphor whose light is well perceived by the ...

New nanomaterial to replace mercury

The nano research team led by professors Helge Weman and Bjørn-Ove Fimland at the Norwegian University of Science and Technology's (NTNU) Department of Electronic Systems has succeeded in creating light-emitting diodes, ...

Record efficiency for perovskite-based light-emitting diodes

Efficient near-infrared (NIR) light-emitting diodes of perovskite have been produced in a laboratory at Linköping University. The external quantum efficiency is 21.6 percent, which is a record. The results have been published ...

Engineered light could improve health, food, suggests researcher

People who believe light-emitting diodes, or LEDS, are just an efficient upgrade to the ordinary electric light bulb are stuck in their thinking, suggest Sandia National Laboratories researcher Jeff Tsao and colleagues from ...

A new generation of organic light-emitting diodes

Another major success for the University of Bayreuth: over the next four years, the university will be coordinating an intercontinental research network that has 3.9 million euros in funding. Taking an interdisciplinary approach, ...

Directivity to improve optical devices

A team of researchers from the Dutch institute AMOLF, Western University (Canada), and the University of Texas (United States of America) recently demonstrated the use of algorithmic design to create a new type of nanophotonic ...
