Flexible FeRAM fabricated with CMOS-compatible approach

flexible_electronicsResearchers have demonstrated the fabrication flexible ferroelectric random access memory (FeRAM) devices using state-of-the-art CMOS processes (sputtering, photolithography, and reactive ion etching). This bridges the existing gap between rigid inflexible semiconductor high performance, integration density, yield, and reliable electronics and highly flexible polymer/hybrid materials based relatively low performance electronics....

Trapping individual metal nanoparticles in air

trapped_nanoparticlesWhile there is a great deal of knowledge on optical manipulation of metallic nanoparticles in liquids, aerosol trapping of metallic nanoparticles is essentially unexplored. In general, very little is known about optical manipulation of any type of particle in air, where the physics appear to be rather different than in water. The just demonstrated ability to manipulate and study individual metallic or semiconductor nanostructures...

3D-shaping graphene - swell it, shrink it, adapt it

nanostructureGetting from 2D to 3D has been quite a challenge for the graphene community. The transfer of two-dimensional graphene onto three-dimensional surfaces has proven to be difficult due to the fractures in graphene caused by local stresses. New research is bound to change that. Scientists have demonstrated graphene integration into a variety of different microstructured geometries - pyramids, pillars, domes, inverted pyramids,...

New 'smart' nanoparticle platform for cancer thermotherapy

thermotherapyMicrowave hyperthermia is one of the most important clinical thermotherapy techniques, however, it is often difficult to apply heat locally to a tumor. By bringing together experts in medicine with experts in nanotechnology, researchers aim to explore the possibilities of designing microwave sensitive agents, which focus the destructive effects of microwaves specifically onto tumor cells. Scientists have now proposed a novel...

Bioinspired nanofur could significantly reduce underwater drag of marine vessels

nanofurObservations made on a fern and an insect have led researchers to develop a nanofur structure that significantly reduces fluid drag. Both have surfaces covered by high density hairs which allow them to keep an air layer under water. This enables the bug to move nimbly and swiftly through the water by reducing the drag on its surface. Based on these observations, researchers have developed a very inexpensive, highly scalable...

A magnetic-assisted, self-healing supercapacitor

magnetic_selfhealingSelf-healing of a device is different from material self-healing because the devices contain electronic circuits. Self-healing of a device includes materials self-healing plus alignment of electrodes, which is very difficult but essential. Researchers have now come up with the idea of using magnetic force to assist alignment of electrodes in a circuit, facilitating self-healing of the whole device. To realize this idea, they...

Novel nanosphere lithography to fabricate tunable plasmonic metasurfaces

nanosphere_lithographyIn conventional nanosphere lithography, the nanosphere configurations in the layers are determined by a spontaneous self-assembly process. Therefore, the final configurations are limited to those with or close to the minimal free energy giving rise to very simple patterns. Researchers have now managed to circumvent this thermodynamical restriction by putting the monolayers in a confined environment and constructing the bilayers...

Synthesizing a boron-rich cousin of graphene

nanosheetsWhile exploring the possibility to realize graphene-like nanostructures of boron, carbon's neighbor in the periodic table, a team of chemical engineers has discovered an entirely new family of 2-D compounds. They demonstrated exfoliation of a well-known superconductor magnesium diboride, a layered material that consists Mg atoms sandwiched in between born honeycomb planes. These nanosheets can be an order of magnitude more...
