Device for Measuring Nanoparticles and Proteins

Malvern Instuments has launched a device suitable for the characterization of proteins and nanoparticles where the highest sensitivity for size and zeta potential measurement is required.

Laboratory Mixer With Stainless Air Motor and Adjustable Stand

Sharpe Mixers has introduced a new laboratory mixer that features a stainless steel air motor.

Comparatively Speaking—Creativity vs. Innovation

In this philosophical discussion, Tony O'Lenick considers the differences between creativity and innovation, and how they can lead to success in the consumer market.

Comparatively Speaking—Water vs. Oil vs. Fluoro vs. Silicone Extraction of Broccoli Fractions

Materials are extracted based on their solubility in different menstrua (solvents), and the spectral subtraction of solvents allows for the identification of groups present in the extracted materials. Given here is an example of how broccoli sprout fractions with four different FTIR spectra were derived using four different silicone polymer menstrua.

Researchers Refine Biomimetic Polymer Synthesis

In a study from the University of Warwick, researchers from the UK and Australia describe a new method to synthesize polymers offering unprecedented control over the final polymer structure.

Comparatively Speaking—Maceration vs. Decoction

Herein, industry expert Tony O'Lenick explains the difference between maceration and decoction, and how decoction can extract large quantities of inert materials that may contribute to microbiological spoilage.

A Dermatological View—The Future of Allergic Contact Dermatitis as it Pertains to Cosmetics

Following are some aspects of patch testing that require consideration, including the ingredients used, related legislative measures and testing limitations.

Fluorescent Biosensor Reveals Immune System Response

Researchers at Carnegie Mellon University have discovered how immune cells exchange information using a new fluorescent biosensor developed at the university.

Survey Finds R&D to Increase in 2012 With Emphasis On Innovation

A survey conducted by the Industrial Research Institute (IRI) has found that R&D spending is expected to increase in 2012. The company's 2012 R&D Trends Forecast also found that new product development will increase in 2012.

New Perspectives in Emulsion Formation

Previously, the theory explaining emulsion behavior was based on the equilibrium contact angle of the particle at the interface; however, Vinothan N. Manoharan, PhD, and his team at Harvard believe the time allowed for the system to reach equilibrium and the force pushing the particle to the interface are equally as important.

Researchers Suggest New Way to Look at Manufacturing Emulsions

Researchers at Harvard's School of Engineering and Applied Sciences (SEAS) have discovered that stabilized emulsions may take months to years to reach equilibrium. This research has important implications for the manufacturing processes used in pharmaceuticals, cosmetics and foods, among other chemical industries.
