New Insights Into the Hydrogen Bonding of Hydrogen Sulphide

What do ice cubes in a drink have to do with the smell of grandma's famous egg salad?

15-Nov-2024 - Water and the bad smelling molecule hydrogen sulphide do not seem to have a lot in common at first sight. However, when investing a little energy, some differences disappear. At first glance, the ice cube in your soft drink and the smell of grandma’s famous egg salad don’t seem to have much in ...

New procedure for better thermoplastics

New insights thanks to nano imaging and spectroscopy at the IRIS beamline of BESSY II

06-Nov-2024 - Bio-based thermoplastics are produced from renewable organic materials and can be recycled after use. Their resilience can be improved by blending bio-based thermoplastics with other thermoplastics. However, the interface between the materials in these blends sometimes requires enhancement to ...

Non-destructive on-site analysis of organic substances using a small modular spectrometer platform

A compact and cost-effective alternative to expensive benchtop devices based on line sensors

04-Apr-2024 - Compact and ultra-compact near-infrared (NIR) spectroscopy systems for the evaluation of organic substances are critical to industries as diverse as food, textiles, and pharmaceuticals. On-site, non-destructive analysis provides confidence in quality control and saves time. The non-resonant ...

Checking items of clothing using a smartphone, AI and infrared spectroscopy

Also suitable for food and skin testing

06-Oct-2023 - Researchers at Fraunhofer have developed an ultra-compact near-infrared spectrometer suitable for recognizing and analyzing textiles. Mixed fabrics can also be reliably identified through the combination of imaging, special AI (artificial intelligence) algorithms and spectroscopy. The technology ...

First comparative study on automated analysis methods of large data sets in microplastics research

27-Mar-2023 - The lack of uniform analytical standards currently prevents the comparability of data on microplastics in the environment. Researchers from the University of Bayreuth and the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have now, for the first time, compared two ...

A pigment from ancient Egypt to modern microscopy

Research team produces new nanosheets for near infrared imaging

25-Mar-2020 - Egyptian blue is one of the oldest manmade colour pigments. It adorns, for instance, the crown of the world famous bust of Nefertiti. But the pigment can do even more. An international research team led by Dr Sebastian Kruss from the Institute of Physical Chemistry at the University of Göttingen ...

Watching complex molecules at work

17-Jan-2020 - A new method of infrared spectroscopy developed at BESSY II makes single-measurement observation and analysis of very fast as well as irreversible reaction mechanisms in molecules feasible for the first time. Previously, thousands of such reactions have had to be run and measured for this ...

Pocket-size food scanner

General-use, cost-effective scanning technology that can be easily adapted

07-Jan-2019 - According to a study by the environmental organization WWF Germany, ten million metric tons of food are thrown in the garbage every year in Germany despite still being edible. A mobile food scanner will allow consumers and supermarket operators in the future to test whether food items have gone ...

Processes at the Surface of Catalysts

Using Infrared Spectroscopy, Scientists Detect that Oxygen Defects Act as Active Centers

12-Apr-2012 - In chemical industry, heterogeneous catalysis is of crucial importance to the manufacture of basic or fine chemicals, in catalytic converters of exhaust gas, or for the chemical storage of solar energy. Scientists of Karlsruhe Institute of Technology (KIT) and Ruhr-Universität Bochum (RUB) have ...

Energy-autonomous sensors in logistics: continuous control of perishable goods

14-May-2010 - The safety and quality in the food supply of today’s globally organized and networked supply chain is everything else than warranted. More than 50% of all foodstuffs are spoiled in the transport routes; alone in Great Britain this makes up 17 million tons and approximately 20 billion Euros. ...
