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 ...

Damage-free way to gauge the health of next-gen batteries for electric vehicles

Electrochemical impedance spectroscopy shows how solid-state lithium metal batteries degrade

20-Sep-2022 - Researchers from Tokyo Metropolitan University have demonstrated that electrochemical impedance spectroscopy (EIS) can be a powerful non-destructive tool to study the degradation mechanisms of all-solid-state lithium metal batteries. They studied ceramic-based all-solid-state Li metal batteries ...

Deeper insight thanks to neutrons from a laser source

The desire to make the hidden visible has always been a driving force of research

28-Mar-2022 - A team led by the Technical University of Darmstadt has for the first time made laser-generated neutrons usable for an industrial application. The researchers showed that neutrons generated compactly with lasers can be used in non-destructive material testing. As electrically neutral particles, ...

New world record in materials research - X-ray microscopy with 1000 tomograms per second

"This method opens a door for the non-destructive study of fast processes in materials, which is what many research groups and also industry have been waiting for"

29-Sep-2021 - Tomoscopy is an imaging method in which three-dimensional images of the inside of materials are calculated in rapid succession. Now a team led by HZB physicist Francisco García Moreno has achieved a new world record at the TOMCAT beamline of the Swiss Light Source at the Paul Scherrer Institute: ...

Laser-based ultrasound approach provides new direction for nondestructive testing

09-Sep-2019 - Many industrial buildings, including nuclear power plants and chemical plants, rely on ultrasound instruments that continually monitor the structural integrity of their systems without damaging or altering their features. One new technique draws on laser technology and candle soot to generate ...

Real-time layer thickness measurement with terahertz

18-Apr-2018 - Terahertz is a key technology for non-destructive material testing. Major advantages are examinations without physical contact and the analysis of complex systems with a low contrast range, in which established methods like ultrasonic usually fail. The Fraunhofer Heinrich Hertz Institute HHI has ...

Exploring nanoscale objects and processes with microwave microscopy

23-Mar-2016 - When lots of energy hits an atom, it can knock off electrons, making the atom extremely chemically reactive and initiating further destruction. That's why radiation is so dangerous. It's also why high-resolution imaging techniques that use energetic electron beams and X-rays can alter, even ...

Detecting material defects in ship propellers

17-Apr-2012 - They can weigh up to 150 tons, and it's not uncommon for them to measure nine meters or more in diameter: the ship propellers on huge tankers, container ships and cruise liners are invisible giants. Damage to these massive propellers could render a ship unmaneuverable – with unpredictable ...
