Long-hypothesized 'next generation wonder material’ created for first time

Scientists have successfully synthesized graphyne, which has been theorized for decades but never successfully produced

25-May-2022

For over a decade, scientists have attempted to synthesize a new form of carbon called graphyne with limited success. That endeavor is now at an end, though, thanks to new research from the University of Colorado Boulder. Graphyne has long been of interest to scientists because of its ...

Microparticles with feeling

Researchers develop a new method to simultaneously measure flow and oxygen - Accurate and fast as never before

25-May-2022

An international research team headed by the Max Planck Institute for Marine Microbiology in Bremen, Aarhus University and the Science for Life Lab in Uppsala has developed tiny particles that measure the oxygen concentration in their surroundings. In this way, they can track fluid flow and ...

Using X-rays to identify liquid chiral molecules

New method can for the first time distinguish their components in liquid form – and more effectively than ever before

25-May-2022

Sugars, amino acids, drugs - chiral molecules are everywhere. Researchers in the AQUACHIRAL project at the Fritz-Haber-Institut have used X-rays to study hair-thin liquid jets of these molecules. Using a new method, they can now for the first time distinguish their components in liquid form – and ...

PFAS chemicals do not last forever

The use of sulfite and iodide under ultraviolet light can destroy PFAS in water in a few hours

25-May-2022

Once dubbed “forever chemicals,” per-and polyfluoroalkyl substances, or PFAS, might be in the market for a new nickname. That’s because adding iodide to a water treatment reactor that uses ultraviolet (UV) light and sulfite destroys up to 90% of carbon-fluorine atoms in PFAS forever chemicals in ...

Surprising turbulence: HZDR team comes across unexpected flow behavior in liquid metals

Implications for battery technology

24-May-2022

Some metals are in liquid form, the prime example being mercury. But there are also enormous quantities of liquid metal in the Earth’s core, where temperatures are so high that part of the iron is molten and undergoes complex flows. A team at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has ...

Spin-off develops and distributes solutions for high-precision multi-material 3D printing

The technology forms a "missing link" for a wide variety of new application areas

24-May-2022

In the framework of an EXIST Transfer of Research project, the HETEROMERGE team is developing a technology for automated material exchange for high-precision 3D printers toward market maturity, enabling multi-material printing even in the area of extremely small structure sizes of down to 100 ...

Researchers develop a membrane that stabilises lithium batteries

"Lithium is just like an unruly child”

24-May-2022

For many people, battery-powered electronic devices like cell phones, laptops, and even electric vehicles, are now a necessity. However, these devices typically require charging at least once a day. Increasing the length of time between charges requires the development of batteries that can store ...

Halogens emitted from oceans amplify global warming of methane in the atmosphere

Iodine, bromine and chlorine transferred from the ocean have increased the lifetime and greenhouse effect of this gas by 6% to 9% over the century.

23-May-2022

An international team, led by researchers from the Spanish National Research Council (CSIC), has performed climate-related chemistry simulations to assess the impact of oceanic emissions of halogenated compounds (iodine, bromine and chlorine) on methane in the atmosphere, the second most ...

Powering a microprocessor by photosynthesis

Algae-powered computing: Scientists create reliable and renewable biological photovoltaic cell

23-May-2022

Researchers have used a widespread species of blue-green algae to power a microprocessor continuously for a year - and counting - using nothing but ambient light and water. Their system has potential as a reliable and renewable way to power small devices. The system, comparable in size to an AA ...
