Quantum Dot Nanocrystals in Neurosciences

Pathak S., Cao E., Davidson M., Jin S., Silva G., UCSD, US

We have developed labeling methods using commercially available quantum dots specific to neurons and glia (Pathak S, in press) and have used these tools to label GFAP intermediate filament cellular bridges as well as integrin [...]

Spontaneously Forming Unilamellar Nano-Sized Vesicles – Polydispersity, Size, Shape and Stability

Nieh M-P, Raghunathan V.A., Huang C-Y, Pencer J., Harroun T., Katsaras J., National Research Council at Canada, CA

Unilamellar vesicles (ULV) made up entirely of biologically relevant materials can serve as carriers for drug delivery or gene therapy. Compared to extrusion and sonication methods, traditionally used for producing ULV, spontaneously forming ULV offer [...]

Molecular Communication among Nanomachines Using Vesicles

Moritani Y., Hiyama S., Suda T., NTT DoCoMo, Inc., JP

Molecular communication is a new and interdisciplinary research area that spans the nanotechnology, biotechnology, and communication technology. Molecular communication allows biological and artificially-created nanomachines to communicate over a short distance using molecules. In molecular communication, [...]

From Helical Starch Inclusion Complexes to Supramolecular Starch Assemblies

Conde-Petit B., Nuessli J., Heinemann C., Escher F., ETH Zürich, CH

Starch, in particular the linear amylose fraction has the ability ot form helical inclusion complexes with suitable guest molecules like monoglycerides, linear alcohols, lactones or terpenes. The helical amylose segments have a strong tendency to [...]

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 [...]

Playing with actuators in microfluidic systems

Tabeling P., Barbier V., Goulpeau J., Lonetti B., Willaime H., ESPCI, FR

In the lab-on a chips of the future, flows will be handled at the microscale through mazes of microchannels. For such systems, it will be crucial to integrate a number of actuators on the chip [...]

Effect of Surface Hydration and Interfusion of Suspended Silica Nanoparticles on Heat Transfer

Milanova D., Wu X., Kumar R., University of Central Florida, US

Nanofluid suspensions enhance thermal conductivity and the heat transfer. The authors have previously shown that the Critical Heat Flux (CHF) of NiChrome wire in a silica nanofluid can be increased by 200% compared to conventional [...]

Controlled production of food emulsion using microfluidics

Pulido de Torres C., Amici E., Gallarino A., Da Silva M., Jousse F., Unilever, UK

We present Microfluidic technology applied to the production of monodisperse emulsion in a food context. We investigate the effect of surfactants and microdevice geometry on drop size and robust production regimes. Minimum drop size achievable in [...]

Investigation of Molecular Rearrangement by AFM Analysis of SAMs Annealing Process

Wu C-L, Hsieh H-Y, Tseng F-G, Chieng C-C, National Tsing Hua University, TW

Self assembly monolayers (SAMs) are easily prepared nano-film, and have been widely applied to improve device surface properties and biomaterial conjugation on substrates. Among various steps, annealing is one of the general processes for the [...]
