System consisting of two Penning traps connected to an electrical resonant circuit transmits the cooling power of laser-cooled ions
For the first time, physicists have succeeded in successfully realizing a new method for cooling protons using laser-cooled ions - in this case beryllium ions. The innovative feature of the new system is that the two particle types are located in spatially separated traps. This means it is now ...
Bioinspired cellulose nanofibrils can be controlled by electricity
Materials science likes to take nature and the special properties of living beings that could potentially be transferred to materials as a model. A research team led by chemist Professor Andreas Walther of Johannes Gutenberg University Mainz (JGU) has succeeded in endowing materials with a ...
Study shows correlation between Twitter sentiment and the valuation of start-ups by venture capitalists
The short message service Twitter has played a prominent role in US politics in recent weeks and months and attracted a lot of attention. Even in business, Twitter users' tweets are being closely followed and used as a basis for decision-making. A new study shows that venture capitalists can also ...
Researchers use electrolysis to produce dichloro and dibromo compounds in a safer and more environmentally friendly manner
Scientists at Johannes Gutenberg University Mainz (JGU) and ETH Zurich have developed a process to produce commodity chemicals in a much less hazardous way than was previously possible. Such commodity chemicals represent the starting point for many mass-produced products in the chemical industry, ...
New approaches to promote the use of nuclear magnetic resonance spectroscopy for analysis in chemistry, biology, and medicine
The diverse work of Mainz-based physicists in the field of nuclear magnetic resonance is being boosted by a new highly application-oriented approach: In October 2020, Dr. Danila Barskiy will join Johannes Gutenberg University Mainz (JGU) to set up a group focusing on nuclear magnetic resonance ...
‘Gamma Factory’ will enable not only breakthroughs in spectroscopy but also novel ways of testing fundamental symmetries of nature
The ‘Gamma Factory initiative’ – an international team of scientists – is currently exploring a novel research tool: They propose to develop a source of high-intensity gamma rays using the existing accelerator facilities at CERN. To do this, specialized ion beams will be circulated in the SPS and ...
Analysis of heterogeneous samples in metal containers using zero- to ultralow-field NMR spectroscopy
Nuclear magnetic resonance (NMR) is employed in a wide range of applications. In chemistry, nuclear magnetic resonance spectroscopy is in standard use for the purposes of analysis, while in the medical field, magnetic resonance imaging (MRI) is used to see structures and metabolism in the body. ...
Scientists propose a promising way to detect parity violation in molecules for the first time
Scientists have long tried to experimentally demonstrate a certain symmetry property of the weak interaction - parity violation - in molecules. So far, this has not been possible. A new interdisciplinary effort led by a research group at the at the PRISMA+Cluster of Excellence at Johannes ...
New technique for measuring the charge state, defects, and capacity losses of rechargeable batteries using atomic magnetometry
Rechargeable batteries are at the heart of many new technologies involving, for example, the increased use of renewable energies. More specifically, they are employed to power electric vehicles, cell phones, and laptops. Scientists at Johannes Gutenberg University Mainz (JGU) and the Helmholtz ...
Physicists explore long-distance information transmission in antiferromagnetic iron oxide
Scientists have succeeded in observing the first long-distance transfer of information in a magnetic group of materials known as antiferromagnets. These materials make it possible to achieve computing speeds much faster than existing devices. Conventional devices using current technologies have ...
