Mycotoxin management in the cereal supply chain: Advanced detection, detoxification, and smart packaging strategies

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Mycotoxins remain a persistent threat to the safety and quality of cereal grains and other agricultural products, and their impact on human health continues to raise global concerns. In many situations, the practices traditionally used to control these toxins are no longer sufficiently effective. They can be costly, difficult to implement on a

Interlaboratory comparison of cosmogenic 21 Ne in quartz [PDF]

Quaternary Geochronology, 2015
We performed an interlaboratory comparison study with the aim to determine the accuracy of cosmogenic 21Ne measurements in quartz. CREU-1 is a natural quartz standard prepared from amalgamated vein clasts which were crushed, thoroughly mixed, and sieved into 125–250 μm and 250–500 μm size fractions.

Beyond Chemical Compliance: A Critical Review Toward Microbiome‐Informed Ecological Exit Criteria for Bioremediated Soils

Land Degradation &Development, EarlyView.
ABSTRACT Chemical compliance remains the usual endpoint for closing contaminated‐soil remediation projects, although it does not establish recovery of soil function or the durability of the post‐treatment state. This critical review examines when microbiological evidence can contribute to ecological closure decisions.

Harmonisation of methane isotope ratio measurements from different laboratories using atmospheric samples [PDF]

Atmospheric Measurement Techniques
Establishing interlaboratory compatibility among measurements of stable isotope ratios of atmospheric methane (δ13C-CH4 and δD-CH4) is challenging. Significant offsets are common because laboratories have different ties to the VPDB or SMOW-SLAP scales ...

Flow cytometric phytoplankton concentration and optical properties across instruments and laboratories

Limnology and Oceanography: Methods, EarlyView.
Abstract Flow cytometry measures the optical properties of individual cells and has become essential for enumerating and characterizing marine phytoplankton. Yet systematic comparison of measurements across instruments remains limited, hampering data comparison across laboratories and long‐term time series.

Seven years of gamma-ray spectrometry interlaboratory comparisons in Switzerland.

, 2010
Since the 1990s, regular comparisons of gamma-ray spectrometry in Switzerland were organized to improve laboratory abilities to measure the radioactivity in the environment and food stuffs at typical routine levels. The activity concentration of the test

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Data‐Independent Acquisition Mass Spectrometry in Tumor Classification and Cancer Biomarker Research

Mass Spectrometry Reviews, EarlyView.
Abstract Cancer treatment is far from optimal also because current classification systems do not reflect the complex molecular status of the tumor and its phenotype in sufficient detail. To construct molecular tumor classifiers, omics tools provide complex molecular data reflecting many aspects from genotype to phenotype.
