By measuring the random jiggling motion of electrons in a resistor, researchers at the National Institute of Standards and Technology (NIST) have contributed to accurate new measurements of the Boltzmann constant, a fundamental scientific value that relates the energy of a system to its temperature. more

An international research group led by Tom Gregorkiewicz, professor at the University of Amsterdam and Yasufumi Fujiwara, professor at Osaka University's Graduate School of Engineering together with his Japanese group at National Institute of Advanced Industrial Science and Technology determined dir more

The Innovation Prize Berlin Brandenburg 2012 was awarded to LUM GmbH for the new Adhesion Analyser LUMiFrac®. Adhesive and tensile strength of composite materials, multi-layer films and bonded parts are determined online by the award-winning LUMiFrac®. Starting as an idea for a more simple and objec more

By amending methodology to utilize eVol® for sample preparation processes for GC-C-IRMS C isotope ratio analysis, the ISORA department has: improved sample preparation conditions and the GC-C-IRMS analysis results by removing the risk of ghost peaks, more

We report the first development of a distance-based paper sensor for a simple, inexpensive, instrument-free, and portable determination of chloride ions. Our analysis reaction is based on the oxidative etching of silver nanoparticles (AgNPs) to form AgCl in the presence of Cl⁻ and H2O2. The H2O2 rea more

In this paper, we explore a variety of aqueous digestion techniques for the determination of gold, in a wide variety of mineral matrices. These include feldspar, basalt, pyrites, and other gold-containing minerals. The acid-based digestion methods compete effectively with fire assay to deliver accur more

This is the tenth Atomic Spectrometry Update (ASU) to focus on advances in elemental speciation and covers a period of approximately 12 months from December 2016. This ASU review deals with all aspects of the analytical atomic spectrometry speciation methods developed for: the determination of oxida more
