Authentication of edible oils has been a long-term issue in food safety, and became particularly important with the emergence and widespread use of gutter oils in recent years. Now, researchers have developed a new method for rapid authentication of edible oils and screening of gutter oils.
Instruments that measure the properties of light, known as spectrometers, are widely used in physical, chemical and biological research. These devices are usually too large to be portable, but scientists have shown they can create spectrometers small enough to fit inside a smartphone camera, using tiny semiconductor nanoparticles called quantum dots.
A new technique reveals atomic-scale changes during catalytic reactions in real-time and under real operating conditions. A team of scientists used a newly developed reaction chamber to combine x-ray absorption spectroscopy and electron microscopy for an unprecedented portrait of a common chemical reaction.
Cancer researchers are collaborating with material scientists to create and use nanotubes to capture and understand the regulation of proteins involved in a variety of diseases including certain cancers, cardiovascular diseases and obesity.
It’s been difficult to explain patterns of toxic mercury in some parts of the world, such as why there’s so much of the toxin deposited into ecosystems from the air in the southeastern U.S., even upwind of usual sources. But, a new analysis shows that one key to understanding mercury’s strange behavior may be the unexpected reactivity of naturally occurring halogen compounds from the ocean.
Creating bacterial “fight clubs” is an effective way to find new drugs from natural sources. That is the conclusion of a team of chemists who have been exploring ways to get bacteria to produce biologically active chemicals that they normally hold in reserve.
Research studying 33 stars found that even stars older than 11-billion-years have Earth-like planets. This constitutes the best characterized set of exoplanet host stars currently available.
If you live in the U.S., you’ve probably seen an odorous house ant– one of the most common ants in the country. For more than 50 years, they’ve been described as smelling like rotten coconut. But they don’t.
The changing global economic picture, environmental pressures and growing demand for specialist applications are driving the requirement for a new generation of instrumentation for polymer development.
X-ray photoelectron spectroscopy allows the intricate depth profiling of lithium batteries, revealing information on components and chemistries that can improve overall performance.
Given recent law and attitude changes in the United States, the cannabis industry is on the rise— which means the cannabis testing industry is likewise growing. From analyzing potency and pesticides to testing for terpenes and residual solvents, chromatography is aptly suited to the analytical needs of the cannabis testing industry.
Shimadzu Scientific Instruments’ iMLayer matrix vapor automated sample treatment (matrix deposition) system provides a precise, high-resolution method for high spatial resolution imaging mass spectrometry.
Applied Rigaku Technologies’ Rigaku NEX QC Quant EZ series of low-cost, high-resolution benchtop energy dispersive X-ray fluorescence (EDXRF) elemental analyzers delivers measurements across a diverse range of matrices—from homogeneous liquids of any viscosity to solids, thin films, alloys, slurries, powders and pastes.
