Researchers present an innovative approach for enhancing electronic devices

28-Oct-2022 - Researchers at Johannes Gutenberg University Mainz (JGU) are pursuing a completely new and unconventional strategy to improve the way data can be processed and – in particular – stored. Together with their partners at the Hebrew University of Jerusalem, they have been granted funding by the Carl ...

Get ready for a new periodic table

Researchers at Hebrew University combine quantum dot 'atoms' and create new 'molecules'

18-Dec-2019 - Are you ready for the future? Back in 1869, Russia's Dmitri Mendeleev began to classify the elements according to their chemical properties, giving rise to the Periodical Table of Elements. "I saw in a dream a table where all elements fell into place as required. Awakening, I immediately wrote it ...

Scientists develop printable water sensor

X-ray investigation reveals functioning of highly versatile copper-based compound

05-Mar-2019 - A new, versatile plastic-composite sensor can detect tiny amounts of water. The 3d printable material, developed by a Spanish-Israeli team of scientists, is cheap, flexible and non-toxic and changes its colour from purple to blue in wet conditions. The researchers lead by Pilar Amo-Ochoa from the ...

14-May-2018 - A new study by Professors Yossi Paltiel of the Hebrew University of Jerusalem and Ron Naaman from the Weizmann Institute of Science describes a breakthrough technology with the power to create drugs with fewer unwanted side effects. Chemical compounds are made up of molecules. The most important ...

Enhancing the quantum sensing capabilities of diamond

24-Nov-2017 - Researchers have discovered that dense ensembles of quantum spins can be created in diamond with high resolution using an electron microscopes, paving the way for enhanced sensors and resources for quantum technologies. Diamonds are made of carbon atoms in a crystalline structure, but if a carbon ...

Enhancing the sensing capabilities of diamonds with quantum properties

26-Sep-2017 - Pure diamond consists of carbon atoms in a perfect crystal lattice. But remove a few carbons and swap some others for nitrogen, and you get a diamond with special quantum-sensing properties. These properties are useful for quantum information applications and sensing magnetic fields, and as a ...

First look inside nanoscale catalysts shows 'defects' are useful

13-Jan-2017 - Using one of the world's brightest light sources to peer inside some of the world's smallest particles, scientists have confirmed a longstanding hypothesis: that atomic disorder or "defects" at the edges of nanoparticles is what makes them effective as chemical change agents. The process by which ...

A compact, efficient single photon source that operates at ambient temperatures on a chip

06-May-2016 - Quantum information science and technology has emerged as a new paradigm for dramatically faster computation and secure communication in the 21st century. At the heart of any quantum system is the most basic building block, the quantum bit or qbit, which carries the quantum information that can ...

Gold nanoparticles reveal fingerprints

04-Apr-2013 - Gold nanoparticles capped with mercaptocarboxylic acids, followed by silver precipitation, have been used to develop latent fingerprints on paper as high quality negative images. Scientists say that the effect stems from hydrogen bonding between the carboxylic group and the paper ...
