Sentences with phrase «tiny nanocrystals»

Researchers in China have developed tiny nanocrystals that could be used in the next generation of medical imaging technologies to light up cancer cells.

Using tiny nanocrystals made of semiconducting materials, the scientists developed a method in which a single nanocrystal can be accurately positioned on top of a specially designed and carefully fabricated nano - antenna.

Not exact matches

To stop nanocrystals getting stuck in tight spots, scientists have been sorting through the tiny tubes to weed out imperfect versions.

Semiconductor nanocrystals, or quantum dots, are tiny, nanometer - sized particles with the ability to absorb light and re-emit it with well - defined colors.

The final product is cellulose nanocrystals, tiny rod - like structures that are 120 nanometers long and have a diameter of 6.5 nanometers.

Their tests with transmission electron microscopy on the nanocrystals, which form as ultrathin films, plates and tiny particles, reveal the desired quality and uniformity.

Using star - shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures — including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals.

The result brings the tiny flakes, called nanocrystals, a crucial step closer to fulfilling their promise of tailoring a laser's color just by changing the size of the crystal, which could lead to more powerful tools for detecting chemicals or sending information via flickers of light.

The researchers found that the composite material not only could control both NIR light and visible light, but that there was «a synergistic interaction in the tiny region where glassy matrix meets nanocrystal that increases the potency of the electrochromic effect,» which means that thinner coatings of the material could pack just as much punch.
