Recycling Greenhouse Gases

Novel perovskite catalysts could be used wherever methane and carbon dioxide are produced simultaneously

05-Sep-2022

CO2 and methane can be turned into valuable products. But until now the catalysts required for such reactions quickly lose their effectiveness. TU Wien has now developed more stable alternatives. Wherever the production of harmful greenhouse gases cannot be prevented, they should be converted ...

Rare insights into growing nanoparticles

“This is a key factor for the design of highly active catalysts and sensors with high sensitivity”

02-Sep-2022

How exactly do nanoparticles form in solution? Researchers from Universität Hamburg and DESY have now been able to observe the growth of nanoparticles in solution in real time. In the journal Nature Communications, they report on their observations using the method of X-ray ptychography, which ...

Particles from everyday wall paints can harm living organisms

Novel membrane shows high filtering effects

22-Aug-2022

Dispersion paints are mostly used in households for painting walls and ceilings. An interdisciplinary research team from the University of Bayreuth has now analysed the chemical composition of two typical dispersion paints and discovered a large number of solid particles in them which are only a ...

Better magnets for green energy

Researchers use multicomponent alloys to make strong and ductile soft magnetic materials

12-Aug-2022

Soft magnetic materials (SMMs) applied in electric engines transform energy from sustainable resources into electricity. Conventional SMMs, which are currently used in industry, are prone to damage under severe mechanical loads. Researchers from the Max-Planck-Institut für Eisenforschung (MPIE), ...

Illinois Tech ‘spinout’ startup Influit Energy has created the world’s first rechargeable, safe, electric fuel

“Discharged fluid can be returned to a recharge/refuel station for recharging or be charged inside the device by plugging into the power source”

09-Aug-2022

It was only a matter of time—beforeInfluit Energywould need to hire more scientists, before the 2,100-square-foot lab space that the company occupies in Chicago’s West Loop neighborhood would grow too small, and before the three co-founders of the startup whose history is inextricably linked to ...

Nanoparticles save historic buildings

Research team investigates nano-crystals for more strength of sandstone at DESY

21-Jul-2022

Many historic buildings were built of sandstone, such as Vienna's St. Stephen's Cathedral. Sandstone is easy to work, but does not withstand weathering well. It consists of sand grains that are relatively weakly bonded to each other, so over the years parts of the stone keep crumbling away, often ...

Future smart homes could be powered with electronics built on stones

Stone microenergy devices could provide high-performance, customizable and conveniently accessible power from natural building materials

13-Jul-2022

What if you could power the smart thermostats, speakers and lights in your home with a kitchen countertop? Stones, such as marble and granite, are natural, eco-friendly materials that many people building or renovating houses already use. Now, in a step toward integrating energy storage with ...

A mirror tracks a tiny particle

Self-interference method

01-Jul-2022

Sensing with levitated nanoparticles has so far been limited by the precision of position measurements. Now, researchers at the University of Innsbruck led by Tracy Northup, have demonstrated a new method for optical interferometry in which light scattered by a particle is reflected by a mirror. ...
