Researchers fine-tune chromatic properties of tungsten trioxide nanodots by adjusting their size, crystallinity, and surface ligands.

Researchers are making strides toward all-optical computing and making access to it, as well as to high-resolution imaging and sensing, easier and more widespread.

Researchers in Japan devise a three-dimensional (3D) full-color display method that relies on an iPhone, rather than a laser, to create holographic images—and it may prove useful...
