Piezoelectric nanomaterials for bio-interface applications

Nanowerk.com - 11 июля, 2017 - 21:05
Nanostructured piezoelectric interfaces own the actual potential to offer beneficial environments for cell and tissue stimulation, and, at the same time, they introduce new scenarios into nanomedicine, where nanomaterials, owing to their 'smart' properties, are exploited as active devices rather than as passive structural units or carriers for medications.

Bacteria on surfaces - strength of adhesion does not depend on size of contact area

Nanowerk.com - 11 июля, 2017 - 16:32
Scientists have developed a method with which they can measure the contact area between a bacterium and the surface it is 'sitting' on. Interestingly a large contact area does not necessarily mean a large adhesive force.

Using graphene as transparent electrodes and alignment layers for liquid crystal devices

Nanowerk.com - 11 июля, 2017 - 10:33
In conventional liquid crystal displays (LCD), the liquid crystal (LC) material is contained in conventional LC cells, where the polyimide layers are used to align the LC homogeneously in the cell, and the transmissive indium tin oxide (ITO) electrodes are used to apply the electric field to reorient the LC along the field. Now, researchers have experimentally demonstrated that monolayer graphene films on the two glass substrates can function concurrently as the LC alignment layers and the transparent electrodes to fabricate an LC cell, without using the conventional polyimide and ITO substrates.

Controlling multi-modal nanolasing with plasmonic superlattices

Nanowerk.com - 10 июля, 2017 - 17:47
Multi-modal lasers can emit at different wavelengths simultaneously and are important for applications ranging from multiplexed signal processing to multi-color biomedical imaging. To achieve multi-wavelength capabilities, however, the single-color lasers need to be operated as an array of lasers, which dramatically increases the unit cost and precludes their integration with compact photonic devices. Researchers now have demonstrated that multi-modal lasing with control over the different colors can be achieved in a single device.
