No transfer of compounds from the bottle material into the oil detected

22-Feb-2023

Bottles made of bioplastic protect cooking oil from oxidative spoilage (rancidity) to a similar extent as PET bottles. In addition, even less taste- and odor-impairing substances were formed. This is the result of a recent study published in the journal "Food Packaging and Shelf Life" by ...

Chemicals from tyre wear could get into our vegetables via sewage sludge and waste water

05-Jan-2023

Wind, sewage sludge, and waste water carry tyre wear particles from roads onto farmland. A new lab study shows: The pollutants contained in the particles could get into the vegetables grown there. Researchers at the Centre for Microbiology and Environmental Systems Science (CMESS) at the ...

Adaptive imaging technique for materials science and structural biology

03-Oct-2022

A new technique that combines electron microscopy and laser technology enables programmable, arbitrary shaping of electron beams. It can potentially be used for optimizing electron optics and for adaptive electron microscopy, maximizing sensitivity while minimizing beam-induced damage. This ...

The study is an example of serendipity in research

27-Jun-2022

The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on the stability of the material can now be determined indirectly while the ...

Scientists say more environmental pollutants should be considered in species protection

20-Jun-2022

Environmental chemical pollution threatens biodiversity. However, the complexity of this pollution remains insufficiently recognised by decision-makers - this is what international researchers led by Gabriel Sigmund from the University of Vienna and Ksenia Groh from the Swiss Federal Institute of ...

Towards new 2D materials

21-Jan-2022

Atoms bind together by sharing electrons. The way this happens depends on the atom types but also on conditions such as temperature and pressure. In two-dimensional (2D) materials, such as graphene, atoms join along a plane to form structures just one atom thick, which leads to fascinating ...

Particles with pompom-like structure

13-Dec-2021

The predictions of researchers that certain particles of matter with sufficiently high density would form a new state - crystalline and flowing at the same time - could be confirmed in the laboratory. More than 20 years ago, researchers predicted that with sufficiently high density certain ...

Quantum computers become ever more powerful, but how can we be sure that the answers they return are accurate? A team of physicists from Vienna, Innsbruck, Oxford, and Singapore solves this problem by letting quantum computers check each other. Quantum computers are advancing at a rapid pace and ...

"We are excited of the prospect of creating new materials that are designed starting at the atomic level, based on this method"

22-Jun-2021

Properties of materials are often defined by imperfections in their atomic structure, especially when the material itself is just one atom thick, such as graphene. Researchers at the University of Vienna have now developed a method for controlled creation of such imperfections into graphene at ...
