Emerging Legal and Product Stewardship Implications of Products of Nanotechnology

Bergeson L.L., Bergeson & Campbell, P.C., US

While the pace of technological innovation is furious, the unambiguous application of law, regulation, and policy, and the implications of nanotechnology for effective product stewardship are moving at far lesser speeds, creating uncertainty and potential [...]

Preparation and Characterization of Highly Dispersive Acrylic Acid/Styrene Submicrocapsules by using Miniemulsion Copolymerization

Ghim H-D, Hwang Y., Kim M.K., Kyungpook National University, KR

This study reports the preparation and characterization of acrylic acid/styrene (AA/St) submicrocapsule having high value of zeta potential by using phytoncide oil as a model material. AA/St submicrocapsules were prepared by miniemulsion copolymerization with 1,3-diphenyl-2-propanone, [...]

Novel encapsulation technology based on Pickering emulsion systems

Sjöö M., Bedi J., Ali A., Speximo AB, SE

A novel technology based on using particles of biological origin for stabilizing emulsions, so called Pickering emulsions, was recently developed. This technology was further employed to encapsulate different types of active substances. Advance development and [...]

Interaction of Beta-Casein with Kappa-Casein Fibrils

Portnaya I., Avni S., Kesselman E., Cogan U., Danino D., Technion – Israel Institute of Technology, IL

Amyloid protein fibrils are associated with numerous degenerative diseases. Kappa casein (kCN) at physiological conditions is known to form amyloid-like fibrils. Although these are not considered disease-related, understanding fibrillization and inhibition of this process may [...]

Solid State and Diffusion NMR Spectroscopy as Applied to Characterization of Complex Formulated Products and Biological Materials

Ulvenlund S., Topgaard D., Gustavsson S., Sparr E., CR Competence AB, SE

Solid and semisolid formulations in pharmaceutics, cosmetics and foods normally comprise complex structures on the molecular and colloidal length scales. Proper understanding of the functionality of a formulated product, as well as rational optimization of [...]

Polysulfone membrane reactors for derivatization of carbon nanotubes

Voicu S.I., Muhulet A., Miculescu F., Miculescu M., Miculescu F., Miculescu M., Vizireanu S., University Politehnica from Bucharest, RO

We propose a new method for derivatization of amino carbon nanotubes with enzymes (carbonic anhydrase, invertase, and diastase) and crown ethers amino derivatives using a polysulfone membrane reactor. The principle of method consist in the [...]

Reduction in HDPE geomembrane thermal expansion using nanoclay particles

Dolez P.I., Mohamed R., David É., Weltrowski M., CTT Group, CA

Polymer membranes have progressively replaced traditional building materials to perform waterproofing functions and control the advective migration of pollutants in civil engineering structures. Either during deployment or in service, geomembranes, 50% of which being made [...]
