Moisture Uptake Characterization in Nanocellulose Using Microwave Cavity

Emiroglu C.D., Natarajan B., Gillman J.W., Liddle J.A., Obrzut J., National Institute of Standards and Technology, US

Nanocellulose has been a continuously emerging area of interest over the recent years due to inexpensive, abundant, and renewable nature of the material source. Cellulose nanocrystals (CNCs) are regarded to be highly useful candidates as [...]

Length amplification of single walled carbon nanotubes for the enrichment of chiral specific nanotubes

Orbaek A.W., Barron A.R., Rice University, US

At Rice University there is a large body of work relating to the development of an “Armchair Quantum Wire”. This would be composed of armchair SWNTs spun into a fiber, that could span global distances. [...]

Plasmon assisted two-photon direct laser writing of micro-structures composed of chiral Ag nanoparticles

Vidal X., Kim W-J, Baev A., S. Jee H., Tokar V., Swihart M.T., The Institute for Lasers, Photonics and Biophotonics, ES

We present an approach to produce micropatterns of metallic nanoparticles (NPs) that preserve key optical properties of the individual NPs. The technique uses a photothermal reaction induced by two-photon direct laser writing. The studied NP [...]

Role of Nano-chirality and broken symmetry in hostile organism penetration of host cell DNA

Vezzoli G.C., Institute for the Basic Sciences, US

We show that broken symmetry, at the nano level, of biomolecules is key to phage invasion of a host cell, and take-over of the cell’s RNA-DNA replication processes. We determined that perturbation of cellular water [...]

Determination of relative concentrations of metallic and semi-conducting SWNTs in suspension via dielectrophoresis

Mureau N., Mendoza E., Hoettges K.F., Silva S.R.P, Hughes M.P., University of Surrey, UK

Dielectrophoresis (DEP) is a phemomenon of induced particle motion in non-uniform electric fields. The effect is frequency dependent; by monitoring the motion of particles in AC fields and ananlysing the change in motion with frequency, [...]
