The as-synthesized nanowires and nanobelts usually have a large size distribution. We demonstrate here a ball milling technique for narrowing the size distribution of oxide nanobelts and nanowires. High-resolution scanning and transmission electron microscopy reveals that the one-dimensional SnO2 nanostructures with size .150 nm are sensitive to the milling effect and most of them were fracture...

How does magnetism behave when the physical dimension is reduced to the size of nanostructures? The multiplicity of magnetic states in these systems can be very rich, in that their properties depend on the atomic species, the cluster size, shape and symmetry or choice of the substrate. Small variations of the cluster parameters may change the properties dramatically. Research in this field has ...

We present a systematic investigation of tunable magnetization dynamics coupled magnetic nanostructures, arranged in one-dimensional arrays horizontally and vertically linear chains two-dimensional square artificial spin ice lattice. The spatial distribution the demagnetization field is markedly sensitive to lattice arrangement, leading significant modification collective behavior static dynami...

Microwave absorbing materials are usually designed to solve protection against electromagnetic interference in wireless communication systems and high frequency circuit mechanisms. In this research polystyrene (PS) nanocomposites containing various nano-fillers were successfully synthesized. The novelty of this work is comparing of three various nanostructures: non-metallic conductive graphene ...
