• New analytical method for detecting the mineral oil contents in foodstuffs resulting from recycled cardboard

  On 22 and 23 September 2011, about 400 representatives from the worlds of science, business and society as well as politics and government institutions discussed how food packaging made of recycled paper could be made safer. Two years ago, mineral oil contents classified as dangerous to health were more

• Quartz crystal microbalances enable new microscale analytic technique
  

  A new chemical analysis technique developed by a research group at the National Institute of Standards and Technology (NIST) uses the shifting ultrasonic pitch of a small quartz crystal to test the purity of only a few micrograms of material. Since it works with samples close to a thousand times sma more

• Scientists show there's nothing boring about watching paint dry

  It turns out that watching paint dry might not be as boring as the old adage claims. A team led by Yale University researchers has come up with a new technique to study the mechanics of coatings as they dry and peel, and has discovered that the process is far from mundane. In the August 9-13 editio more

• UV/Vis/NIR Spectrometry for the Film Thickness Determination of Transparent Films and Layers
  

  Within nearly all branches of industry we find products, which are coated with thin transparent layers to improve the surface features: Window sheet glasses obtain changes in reflection and absorption behavior, ceramics are treated with coatings to lower water adhesion, coatings on metals create corrosion resistance or better sliding factors. Transparent coatings play also a major role in the semiconductor business. One of the important features to be determined and controlled is the thickness of the layers to balance performance and material input during development and production more

• Good Reasons to Use ATR Libraries
  

  Transmission spectroscopy was the only method in general use until the early 1960s. The first applications of attenuated total reflection (ATR) or internal reflection spectroscopy were reported independently by Fahrenfort and Harrick. Especially macromolecular materials (rubbers, fibers, fabrics, coatings, laminates etc), which often failed to yield useful transmittance spectra, became accessible for infrared spectroscopic investigations by the ATR technique. Meanwhile, the ATR technique has been proven to be an extremely useful technique for material analysis and has become more widely used for all but gaseous samples. more
