High-precision distributed sensing using an entangled quantum network (22/01/2020)

Quantum-enhanced metrology has been an active area of research for several years now due to its many possible applications, ranging from atomic clocks to biological imaging. Past physics research established that having a non-classical probe, such as squeezed light or an entangled spin state, can have significant benefits compared to classical probes. This idea was explored further in several recent works, some of which also considered the benefits of examining multiple distinct samples with non-classical probes.

Advanced polymers help streamline water purification, environmental remediation (22/01/2020)

It takes a lot of energy to collect, clean and dispose of contaminated water. Some contaminants, like arsenic, occur in low concentrations, calling for even more energy-intensive selective removal processes.

Determining the atomic structure of natural products more rapidly and accurately (22/01/2020)

Many drugs are derived from natural products. But before natural products can be exploited, chemists must first determine their structure and stereochemistry. This can be a major challenge, particularly when the molecules cannot be crystallized and contain only few hydrogen atoms. A new NMR-based method, developed at the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP), now simplifies the analysis and produces more accurate results. The work has been published in the Journal of the American Chemical Society.

Making computers and smartphones more energy efficient with novel tiny structures (20/01/2020)

With enhanced properties such as greater strength, lighter weight, increased electrical conductivity and chemical reactivity, nanomaterials (NMs) are widely used in areas like ICT, energy and medicine. For example, nanotubes, nanorods and nanowires with different size, structure and chemical composition have been successfully synthesised for various applications in mechanical, electromechanical, electric and optoelectronic devices.

'Universal memory' research passes new milestone (20/01/2020)

Physicists at Lancaster University have demonstrated that their invention of a new type of memory device could transform the way computers, smartphones and other gadgets work.

Memory storage for super cold computing (17/01/2020)

Scientists at the Department of Energy's Oak Ridge National Laboratory have experimentally demonstrated a novel cryogenic, or low temperature, memory cell circuit design based on coupled arrays of Josephson junctions, a technology that may be faster and more energy efficient than existing memory devices. If successfully scaled, this type of cryogenic memory array could advance a variety of applications including quantum and exascale computing.

The mysterious movement of water molecules (16/01/2020)

Water is ubiquitous and essential for life. Nevertheless, experimental information about its behaviour on the atomic level—above all how it interacts with surfaces—is scarce. Thanks to a new experimental method, TU Graz researchers have now delivered insights into the atomic-level movement of water molecules, which they outline in a paper in Nature Communications.

Researchers demonstrate first stable semiconductor neutron detector (16/01/2020)

Homeland Security might soon have a new tool to add to its arsenal. Researchers at Northwestern University and Argonne National Laboratory have developed a new material that opens doors for a new class of neutron detectors.

New method produces robust transistors (16/01/2020)

A new method to fit together layers of semiconductors as thin as a few nanometers has resulted in not only a scientific discovery but also a new type of transistor for high-power electronic devices. The result, published in Applied Physics Letters, has aroused huge interest.

New mechanisms describe how the genome regulates itself (16/01/2020)

An organism's genome contains all of the information necessary for each of its cells and tissues to develop and function properly. Written in DNA, each individual gene encodes for something, whether it is a structural protein that helps define a tissue's shape, an enzyme that catalyzes the chemical reactions of life, or a signaling protein that cells use to communicate.
