Two is better than one: Single-atom dimer electrocatalyst for green hydrogen production

Nickel-cobalt metal dimer on nitrogen-doped carbon can catalyze electrolysis under both acidic and basic conditions

23-Nov-2021 - The limited reservoir of fossils fuels and the ever-increasing threats of climate change have encouraged researchers to develop alternative technologies to produce eco-friendly fuels. Green hydrogen generated from the electrolysis of water using renewable electricity is considered a ...

Improving zinc oxide nanorods’ performance in piezoelectric nanogenerators

09-Jan-2013 - Scientists in the Republic of Korea have treated zinc oxide nanorods in piezoelectric nanogenerators (which use mechanical vibrations, such as body movement and air flow, to power electronic devices) to a thermal annealing process to improve their output voltage (output was 25 times higher than ...

The thinnest, smoothest metallic lines in the world helps speed up miniaturisation of electronic devices

New method creates super-thin, high integrity, continuous metal lines that surpass today’s semiconductor industry requirements

06-Jul-2010 - Scientists from Singapore A*STAR’s Institute of Materials Research and Engineering (IMRE), University of Cambridge (UK) and Sungkyunkwan University (South Korea) have created metallic lines so thin and smooth that they can only be seen using powerful electron microscopes. This research will be ...
