Scientists shed light on organic photovoltaic characteristics

Scientists have developed a method that allows the prediction of the current density-voltage curve of a photovoltaic device. This new method uses a common measurement technique (impedance spectroscopy) that is affordable, widely available to manufacturers, and relatively easy to perform.

Inhomogeneous surface plasmon polaritons

Scientists have discovered a new way to control light. Light can be guided along the surface of a metal via a surface plasmon polariton phenomenon. When light guided along the surface of one metal encounters a different metal surface, the new type of plasmon called an 'inhomogeneous surface plasmon polariton' results that has controlled confinement properties.

Accounting for biological aggregation in heating and imaging of magnetic nanoparticles

Biological aggregation is a critical, yet often overlooked factor in the medical application of nanoparticles. Here scientists systematically characterize the effects of aggregation on both radiofrequency heating and magnetic resonance image (MRI) contrast of magnetic iron oxide nanoparticles, including detailed analysis of the aggregate morphologies based on quasi-fractal descriptions.

Single laser stops molecular tumbling motion instantly

In the quantum world, making the simple atom behave is one thing, but making the more complex molecule behave is another story. Now scientists have figured out an elegant way to stop a molecule from tumbling so that its potential for new applications, such as quantum computing, can be harnessed: shine a single laser on a trapped molecule and it instantly cools to the temperature of outer space, stopping the rotation of the molecule.
