Remote control of mechano-sensory function of primary cilia by Fe2O3 nanoparticles in ciliopathic animal models

Pala R., Nauli S.M., Chapman University and University of California Irvine, US

In the present studies, we designed a cilia-targeted delivery system to deliver fenoldopam (FD) specifically to the primary cilia. Hence, we devised the iron oxide nanoparticle (Fe2O3-NP)-based technology for ciliotherapy. Dynamic light scattering measurements showed [...]

Magnetic properties of metallic AuPdO nanoparticles confined in ordered mesoporous silica SBA-15 channels

Iwamoto W., Lesseux G.G., Dias B.F., Teixeira-Neto A.A., Teixeira-Neto E., Teixeira-Neto A.A., Teixeira-Neto E., Urbano R.R., Rettori C., Universidade Estadual de Campinas (UNICAMP), BR

Materials consisting of metallic AuPdO nanoparticles (AuPdO-NPs) supported on mesoporous silica SBA-15 channels (AuPdO-NPs/SBA15, Figure 1) have become composite compounds of great interest due to their catalytic applications [1]. In this work we report on [...]

Electron pairing instabilities and magnetic properties in nanoclusters and nanomaterials

Kocharian A.N., Fernando G.W., Fung K., Palandage K., California State University Los Angeles, US

Studies of assembled clusters, nanoparticles and optical lattices in various topologies provide intriguing insights into several many body problems in condensed matter physics1. A new, emerging guiding principle for the search of new materials can [...]

A facile block copolymer inclusion technique for large scale monodisperse hexagonal arrays of superparamagnetic iron oxides nanodots

Ghoshal T., Maity T., Godsell J.F., Roy S., Morris M.A., University College Cork, IE

We demonstrate a simple and cost-effective route, based around block copolymer patterning, to create dense arrays of highly ordered iron oxide nanodots at substrate surface. The methodology creates hexagonally arranged features via a process of [...]

Electron instabilities in nanoclusters, nanostructures and inhomogeneous nanomaterials: bottom up approach

Kocharian A., California State University Los Angeles, US

Inhomogeneous nanomaterials with strong local electron correlations are creating a new world-view in condensed matter physics [1-4]. These materials with intrinsic ihomogeneities have electronic and magnetic properties that are widely different from the conventional materials. [...]

Surface Enhanced Raman Utilizing Magentic Core Silver Shell Nanoparticles

Glaspell G.P., UACE ERDC, US

SERS is an extremely sensitive technique exploited in laboratory investigations to provide single molecule detection. In sensor applications, this sensitivity has not been fully realized in part due to the low scattering efficiency. We hypothesize [...]

Spin Dependent Transport in Carbon Nanostructures

Harrison N.M., Montanari B., Imperial College London, UK

A theoretical investigation of the electronic and magnetic structure in carbon nanoribbons, defective graphene and carbon peapod structures. The critical importance of electron correlation in the emergent behaviour will be demonstrated for; the generation of [...]

Oxygen Vacancies induced ferromagnetism in undoped and Cr doped SnO2 nanowires

Zhang L., Ge S., Zuo Y., Jing Q., Lanzhou University, CN

Observations of room temperature ferromagnetism (FM) in various pristine oxides have been reported recently. The findings have urged researchers to explore the origin of FM, but there is no uniform model to explain this issue [...]

Magnetic properties of Sputter deposited and magnetically annealed IrMn/CoFeB nanometric bilayers for exchange biased magnetic tunnel junctions

Fulara H., Raju M., Chaudhary S., Kashyap S.C., Pandya D.K., Inidan Institute of Technology Delhi, IN

The work relates to the exploring the means of controlling the coercivities of the ferromagnetic thin films in a Magnetic Tunnel Junction Stack. Exchange bias route is a very powerful route in achieving this task. [...]
