Improving image sensors for machine vision

Image sensors measure light intensity, but angle, spectrum, and other aspects of light must also be extracted to significantly advance machine vision.

Metamaterial significantly enhances chiral nanoparticle signals

The left hand looks like the right hand in the mirror but the left-handed glove does not fit on the right hand. Chirality refers to this property where the object cannot be superimposed on to the mirror image. This property ...

Evanescent scattering microscopy: A sharper image for proteins

Proteins may be the most important and varied biomolecules within living systems. These strings of amino acids, assuming complex 3-dimensional forms, are essential for the growth and maintenance of tissue, the initiation ...

Ultrafast electron dynamics in space and time

Often depicted as colorful balloons or clouds, electron orbitals provide information on the whereabouts of electrons in molecules, a bit like fuzzy snapshots. In order to understand the exchange of electrons in chemical reactions, ...

Nanoscale machines convert light into work

Researchers have developed a tiny new machine that converts laser light into work. These optically powered machines self-assemble and could be used for nanoscale manipulation of tiny cargo for applications such as nanofluidics ...
