Why does the universe favor matter over antimatter? The first glimpse of data from the full array of a deeply chilled particle detector operating beneath a mountain in Italy sets the most precise limits yet on where scientists might find a theorized process to help explain why there is more matter than antimatter in the universe. This new result is based on two months of data from the full detector of the CUORE (Cryogenic Underground Observatory for Rare Events) experiment at the Italian National Institute for Nuclear Physics’ (INFN’s) Gran Sasso National Laboratories (LNGS) in Italy. CUORE means “heart” in Italian.

CUORE is considered one of the most promising effo...

Pinning DNA-sized ribbons of carbon to a gas sensor can boost its sensitivity far better than any other known carbon material, says a new study from the University of Nebraska-Lincoln. When the researchers integrated a film of graphene nano-ribbons into the circuitry of a gas sensor, it responded about 100X more sensitively to molecules than did sensors featuring even the best-performing carbon-based materials...

A research team led by Associate Professor Christian Nijhuis from the Department of Chemistry at the NUS Faculty of Science (second from right) has recently invented a novel “converter” that can harness the speed and small size of plasmons for high frequency data processing and transmission in nanoelectronics.

Invention bagged 4 patents and could potentially make microprocessor chips work 1000X faster. Advancement in nanoelectronics has been fueled by the ever-increasing need to shrink the size of electronic devices in a bid to produce smaller, faster and smarter gadgets such as computers, memory storage devices, displays and medical diagnostic tools.

While most advanced electronic devices are powered by photonics – which involves the use of photons to transmit information – photonic e...

Ferroelectric self-assembled molecular materials. Scientists have developed the first material with conductivity properties that can be switched on and off using ferroelectric polarization. Professor Martijn Kemerink of Linköping University has worked with colleagues in Spain and the Netherlands to develop the first material with conductivity properties that can be switched on and off using ferroelectric polarisation. The phenomenon can be used for small and flexible digital memories of the future, and for completely new types of solar cells.

The research group shows the phenomenon in action in three specially built molecules, and proposes a model ...
