Figure 1: Colloidal crystals on curved oil–glycerol interfaces. The topology of surfaces 21 places a constraint on the total defect charge—for example the net charge on a sphere must be 4π, as ...

Physicists have succeeded in creating a defect in the structure of a single-layer crystal by simply inserting an extra particle, and then watching as the crystal "heals" itself. In a paper just ...

An international team of researchers, led by University of Toronto Engineering Professor Yu Zou, is using electric fields to control the motion of material defects. This work has important ...

Based on a small amount of basic information about a crystal's structure, the Oldenburg researchers' programme calculates the properties of complex new materials. Computer-based methods are becoming ...

(Nanowerk News) Research groups at Johannes Gutenberg University Mainz (JGU) and the Physical-Technical Federal Institute (PTB) in Braunschweig, working in collaboration with scientists at the ...

The interaction of ultrasound with surface-breaking slots has been used to characterize the slots, with laser generation of ultrasound providing the short-duration Rayleigh pulses used as the probe.

A new study examining how ice forms from pure water found that the geometry of the surface that water is on can have an effect on whether or not it freezes, suggesting that surface geometry plays an ...

SiC is extensively used in microelectronic devices owing to its several unique properties. However, low yield and high cost of the SiC manufacturing process are the major challenges that must be ...
