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 [...]

Rheological performance and NMR structure investigation of ultrasound crumb rubber modified bitumen

Filippelli L., Antunes F.E., Gentile L., Spadafora A., Ranieri G.A., Rossi C.O., University of Calabria, IT

Rubber from tyres is a waste material with a highly valuable constituents. the introduction of crumb rubber in the production of asphalt rubber (AR) mixes for road pavements should be considered as a sustainable technology [...]

Nanostructure of Interfaces and Giant Magnetoresistance of Co/Cu Superlattices

Chuprakov S.A., Verhovsky S.V., Krinitsina T.P., Bannikova N.S., Blinov I.V., Milyaev M.A., Popov V.V., Ustinov V.V., Institute of Metal Physics, RU

The structure, the state of interfaces and magnetoresistance of [Co(1.5nm)/Cu(0.9nm)]n superlattices have been studied. The magnetoresistance decreases with the growth of n from 38% for n = 10 to 24% for n = 40. TEM [...]

A structural analysis of olive oil organogelation

Filippelli L., Gentile L., Lupi F.R., Rossi C.O., Baldino N., Ranieri G.A., Gabriele D., University of Calabria, IT

Organogels based on liquid vegetable oils are possible replacers of saturated or hydrogenated fats in the food industry. There is still a lack of information about the link between macroscopic parameters and material microstructure. By [...]

Imaging Molecules and cells

Sharma R., Florida State University and TCC, US

Proteins provide the building blocks for multicomponent molecular units, or pathways, from which higher cellular functions emerge. These units consist of either assemblies of physically interacting proteins or dispersed biochemical activities connected by rapidly diffusing [...]

Morphological Implications of the Interphase; Linking Crystalline and Amorphous Regions in Semi-Crystalline Polymers

Rastogi S., Terry A.E., Eindhoven University of Technology, NL

In semi-crystalline polymers, a range of morphologies can be obtained in which a chain may traverse the amorphous region between the crystals or fold back into the crystals leading to adjacent or non-adjacent re-entry, depending [...]

Quantum Information Processing with Nuclear Spin-Based Devices

Havel T.F., Cappellaro P., Ramanathan C., Cory D.G., Massachusetts Institute of Technology, US

This talk will illustrate the benefits offered by QIP with two devices which use quantum entanglement among nuclear spins to defeat the Heisenberg limits: (1) a spin gyroscope that operates by detecting the frequency shift [...]
