Collective Behavior of an Array of Spin Torque Nano-Oscillators

Buono P.L., Dabrowski C., Palacios A., Turtle J., In V., San Diego State University, US

As predicted by Slonczewski and Berger, a spin-polarized current can exert a torque on the magnetization of a ferromagnetic layer leading to precession. Then the Giant Magnetoresistance Effect (GMR) can convert the magnetic precession into [...]

Alkali Halide Nanoclusters: Structure, Stability, Properties and Mechanism of Formation

Henkes A.V., Fantuzzi F., Nascimento M.A.C., Instituto de Química, Universidade Federal do Rio de Janeiro, BR

Results of accurate quantum-mechanical calculations for alkali halide nanoclusters (LiF, NaCl, KBr), revealed a variety of new morphologies - single and multiple tubes, double-sheets, honeycomb, sodalitic cages- quite distinct from the cubic macro crystal structure. [...]

Molecular Dynamics Simulations of Polytetrafluoroethylene at Glassy Transition Temperature

Al-Nsour R., Virginia Commonwealth University, US

This research is concerned with studying and understanding the thermal and mechanical behavior of PTFE. Such understanding is critical to predicting PTFE behavior and allowing bottom up design of improved polymers for specific applications. While [...]

Modeling of Graphene Functionalization by F- and FHF- Ions from Associates with Water Molecules

Lvova N.А., Ananina О.Yu., Technological Institute for Superhard and Novel Carbon Materials, RU

In this paper, we simulated the adsorption of fluorine on the surface of mono- and polycrystalline graphene from F- and FHF- ions associates with water molecules. As model objects, we used graphens without grain boundaries, [...]

Inductive Nano Targeted Electromagnetic Therapy

Meymanat M., Zanjan University of Medical Sciences, Zanjan, Iran, IR

A Biofunctionalized conductor Nano-Particle which can be made of ferromagnetic and conductor materials, capable to attach specifically biologic targets in vivo and in vitro by using molecules for specific attachment (such as monoclonal antibody) is [...]

Cu/TiO2-SiO2 Nanostructured Materials for Brain Cancer Treatment

Ortiz-Islas E., Guevara P., Gómez E., Monroy H., Novaro O., National Institute of Neurology and Neurosurgery, MX

In the present work, we are reporting the toxic effect to brain cancer cells exerted by copper complexes loaded (CC) on a binary oxide. For this purpose, the TiO2-SiO2 oxide was prepared using the sol-gel [...]

Thymoquinone nanoparticle formulation and in vitro efficacy

Fakhoury I.H., Saad W.S., Gali-Muhtasib H.U., Schneider-Stock R., American University of Beirut, LB

The work summarized here pertains to the formulation of thymoquinone into controlled size nanoparticles using a recently developed solvent precipiation technique termed Flash Nanoprecipiation. Using a diblock copolymer of poly(styrene-b-ethylene oxide) as the stabilizing polymer, [...]

Nanodelivery of Cerebrolysin as adjunct therapy with Functionalized magnetic iron oxide nanoparticles enhances neuroprotection

Sharma A., Sharma H.S., Muresanu D.F., Tian Z.R., Moessler H., Sharma A., Sharma H.S., Uppsala University, SE

1. Functionalized magnetic iron oxide nanoparticles (FMIONPs) are used as adjunct therapy in cancer to effectively enhance cellular damages of cancerous cells sparing normal cells using chemotherapy or heat treatment. The FMIONPs are considered safe. [...]

Study on the Composite with Sequential and Sustained Release of Multiple Growth Factors for Bone Repair

Liao Y., Liu T.Y., Institute of Biomedical Engineering, National Yang-Ming University, TW

In this study, a PLGA/PVA microsphere and a chitosan-based hydrogel loading FITC were prepared to be a composite. The encapsulation of FITC in PLGA/PVA microspheres and the bonding of crosslink in chitosan-based hydrogel were confirmed. [...]
