New type of engineered carbon nanomaterial is capable of changing shapes and colors

Researchers have presented a unique design and synthesis of hybrid carbon nanosheets, which show a strong solvatochromic behavior with wide color tunability ranging from blue to orange and even to white in various solvents.

Piezoelectric nanomaterials for bio-interface applications

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.

Novel techniques examine solar cells with nanoscale precision

The new techniques, which investigated a common type of solar cell made of the semiconductor material cadmium telluride, promise to aid scientists in better understanding the microscopic structure of solar cells and may ultimately suggest ways to boost the efficiency at which they convert sunlight to electricity.
