A mobile breakthrough for water environment monitoring

A novel colorimetric multi-channel sensor on cell phone platform

26-Jan-2023

Reliable colorimetric analysis technologies have been widely praised for their highly sensitive and selective responses towards various contaminants in environmental monitoring. In principle, the chromogenic agent selectively reacts with the target in water samples, and the colored product ...

Researchers develop new method for X-ray colour imaging

Colour images from the shadow of a sample

25-Jan-2023

A research team at the University of Göttingen has developed a new method to produce X-ray images in colour. In the past, the only way to determine the chemical composition of a sample and the position of its components using X-ray fluorescence analysis was to focus the X-rays and scan the whole ...

Atoms of a glass jump similarly to cosmic particles

X-ray experiment shows possible novel route for tailoring properties of glasses: “The story appears to be getting more interesting”

23-Jan-2023

For thousands of years, people around the world have experimented with different ways to make glasses with varying properties by heating them until they melt then cooling them again. A team led by scientists at the University of Padua in Italy have used DESY’s PETRA III X-ray light source to ...

Quantum simulator enables first microscopic observation of charge carriers pairing

Research results could be key to understanding high-temperature superconductors

23-Jan-2023

A team of researchers at the MPQ has for the first time monitored in an experiment how holes (positive charge carriers) in a solid-state model combined to form pairs. This process could play an important role in understanding high-temperature superconductivity. Using a quantum simulator, ...

Researchers cast new light on magnons to verify topological phases in magnetic materials

“Raman scattering is a standard experimental technique available in many labs, which is one of the strengths of this proposal”

19-Jan-2023

Much recent research has focused on ‘topological’ materials – an intriguing type of solids which fall outside the standard classification into insulators and conductors. While their bulk is insulating, these phases are characterized by electrically conducting channels which appear at their edges. ...

Bayesian inference massively cuts time of X-ray fluorescence analysis!

Saved seconds add up to hours over multiple measurements

10-Jan-2023

How can the component elements of an unknown material, such as a meteorite, be determined? X-ray fluorescence analysis can be used to identify an abundance of elements, by irradiating samples with X-rays and analyzing the spectrum they emit and can detect many elements simultaneously. For this ...

Using machine learning to improve the toxicity assessment of chemicals

Chemists take a new approach to testing chemicals

30-Dec-2022

Researchers of the University of Amsterdam, together with colleagues at the University of Queensland and the Norwegian Institute for Water Research, have developed a strategy for assessing the toxicity of chemicals using machine learning. They present their approach in an article in Environmental ...

New X-ray imaging technique to study the transient phases of quantum materials

An international team of researchers has demonstrated for the first time the use of a new lensless ultrafast X-Ray method to image phase transitions

27-Dec-2022

The use of light to produce transient phases in quantum materials is fast becoming a novel way to engineer new properties in them, such as the generation of superconductivity or nanoscale topological defects. However, visualizing the growth of a new phase in a solid is not easy, due in-part to ...
