A potential long-lasting nano treatment for sensitive teeth

Rather than soothe and comfort, a hot cup of tea or cocoa can cause people with sensitive teeth a jolt of pain. But scientists are now developing a new biomaterial that can potentially rebuild worn enamel and reduce tooth sensitivity for an extended period.

Microfluidics to accelerate cell membrane research

Life processes depend fundamentally on phenomena occurring on the membranes separating cells from their environment. Hitherto poorly understood, the mechanisms responsible for transport through the cell membrane will be able to be studied faster and more cheaply - thanks to a new microfluidic system. The system enables the serial formation of cell membranes and measurement of the processes taking place on them.

A novel nanobowl optical concentrator for organic solar cell

Geometrical light trapping is a simple and promising strategy to largely improve the optical absorption and efficiency of solar cells. Nonetheless, implementation of geometrical light trapping in organic photovoltaic (OPV) is challenging due to the fact that uniform organic active layer can rarely be achieved on textured substrate. Researchers have now reported novel nanobowl optical concentrator fabricated on low-cost aluminum foil and aiming at tackling this problem.
