Nanoscale salt baskets up close (w/ Video)

The electron microscope images below, reminiscent of man-made baskets or children's blocks, shows cubic salt crystals that have been forced to form in spheres, as Rox Middleton explains.

New player emerges in mapping protein structures

(Phys.org) —If you keep up with biology, you've probably seen those colorful images in which the atom-by-atom structure of a protein is portrayed by a tangle of ribbons. For the past couple of decades, scientists have been ...

Global first as Witsies split pollen

Wits researchers have become the first to cut sections through pollen grains and make it possible to view a three dimensional image of the internal wall. This positions them to determine how the characteristics of the internal ...

New imaging tool directly measures liquid surfaces

(Phys.org) —A unique chemical imaging tool readily and reliably presents volatile liquids to scientific instruments, according to a team including Pacific Northwest National Laboratory. These instruments require samples ...

Kinks and curves at the nanoscale

One of the basic principles of nanotechnology is that when you make things extremely small—one nanometer is about five atoms wide, 100,000 times smaller than the diameter of a human hair—they are going to become more ...

Microfluidic devices move from application to fundamental science

(Phys.org) —Just a few drops of liquid or a bit more is run past specialized sensors in microfluidic devices to detect chemicals of concern to doctors and security personnel. However, these devices are now being reinvented ...
