Optical coherence tomography shines with a new type of contrast

A diagnostic workhorse, optical coherence tomography (OCT), provides high-resolution 3-D imaging of subsurface tissue structures. Most likely, for your last eye exam, the ophthalmologist took cross-sectional pictures of your ...

Quantum phenomenon governs organic solar cells

Researchers at Linköping University have discovered a quantum phenomenon that influences the formation of free charges in organic solar cells. "If we can properly understand what's going on, we can increase the efficiency," ...

Silver sawtooth creates valley-coherent light for nanophotonics

Scientists at the University of Groningen used a silver sawtooth nanoslit array to produce valley-coherent photoluminescence in two-dimensional tungsten disulfide flakes at room temperature. Until now, this could only be ...

Surprising discovery could change the way industry uses nickel

Nickel is one of the most abundant elements on earth. It is hard, yet malleable, magnetic at room temperature, and a relatively good conductor of electricity and heat. Most notably, nickel is highly corrosion resistant, which ...

Eye imaging technology provides opportunities in biotechnology

In her doctoral dissertation, M.Sc. Sanna Haavisto, researched the flow properties of aqueous microcellulose suspensions. Optical coherence tomography, an imaging technology commonly used in medical imaging of eye, was applied ...

Creating 'movies' of thin film growth

From paint on a wall to tinted car windows, thin films make up a wide variety of materials found in ordinary life. But thin films are also used to build some of today's most important technologies, such as computer chips ...
