• Making good taste measurable

  Does milk chocolate still contain milk? Or does cheaper vegetable fat already dominate here? Has the barrique wine really seen the inside of a barrique barrel or has it been spiked with flavoured woodchips? Both the products of global food manufacturers as well as small, traditional foodstuffs à la more

• Investigating how spiders spin their silk, researchers unravel a key step

  Five times the tensile strength of steel and triple that of the currently best synthetic fibers: Spider silk is a fascinating material. But no one has thus far succeeded in producing the super fibers synthetically. How do spiders form long, highly stable and elastic fibers from the spider silk prote more

• Heinrich Emanuel Merck Award for 2010 granted to leading Italian scientist

  Merck KGaA announced that the 2010 Heinrich Emanuel Merck Award for Analytical Sciences will go to Luisa Torsi, Professor of Analytical Chemistry at the University of Bari in Italy. This marks the first time that the award has been given to a woman and to a scientist in Italy. The award, which is wo more

• Polyether-Modified Silicones for Cosmetic Applications
  

  Polyether-modified silicones have a long history of use in the personal care industry as emulsifiers and dispersants, as well as stabilizers for water-in-oil systems. However, because of their external phase type, water-in-oil systems tend to display poor aesthetics, such as greasiness, tackiness and slow absorption. A new polyether-modified silicone, PEG/PPG-19/19 dimethicone (and) C13-16 isoparaffin (and) C10-13 isoparaffin, was evaluated for its potential to aid in the production of stable water-in-silicone and water-in-oil formulations with unique textures and enhanced aesthetics. Various oil phases were studied, including silicone oils, organic oils, and a combination of both. Results of the evaluations demonstrate the versatility of the new material, and prototype formulations illustrate its broad utility more

• Particle Analysis: Quality Control of Catalysts with Digital Image Processing
  

  Catalysts are widely used as an important auxiliary material in the chemical and petrochemical industry. They are able to accelerate chemical reactions by lowering the activation energy, i.e. they change reaction kinetics. Thus, using catalysts in industrial processes has the advantage of higher productivity combined with less energy consumption. more

• Particle shape - an important parameter in pharmaceutical manufacturing
  

  The advent of rapid and reliable measurement technologies, together with the FDA's PAT (Process Analytical Technologies) initiative, has increased the use of particle shape analysis within the pharmaceutical industry. Particle shape, like particle size which is routinely measured and controlled, can directly influence product performance and its measurement can lead to improved process and product understanding. Here we consider the importance of particle shape measurement for the pharmaceutical industry, with reference to the aims of the PAT initiative, and highlight the modern image analysis techniques available for sensitive size and shape characterization. more
