Materials researchers have fine-tuned a technique that enables them to apply precisely controlled silica coatings to quantum dot nanorods in a day -- up to 21 times faster than previous methods ...

Silica-coated gold nanorods are dispersed in ethanol, a polar solvent. In ethanol, the hydrogen atoms are partially positively charged, and the oxygen atoms are partially negatively charged.

In 2019, his group showed that a porous liquid made by combining hollow silica nanorods and a polymer (wetting agent) could capture carbon dioxide at room temperature.

(Nanowerk News) Researchers have fine-tuned a technique for coating gold nanorods with silica shells, allowing engineers to create large quantities of the nanorods and giving them more control over ...
