ORNL devises recipe to fine-tune silica rod diameters

Posted at 7:31 pm December 20, 2013

By controlling the temperature of silica rods as they grow, researchers at Oak Ridge National Laboratory could be setting the stage for advances in anti-reflective solar cells, computer monitors, TV screens, eye glasses, and more.

The goal of fabricating fixed-size one-dimensional silica structures and being able to precisely control the diameter during growth has long eluded scientists. Now, Panos Datskos and Jaswinder Sharma have demonstrated what they describe as the addressable local control of diameter of each segment of the silica rod.

“In nature, many intricate structures develop and grow in response to their environments,” said Sharma, a Wigner Fellow and corresponding author of the Angewandte Chemie International Edition paper that outlines the process. “For example, in addition to genotype, shell shape is also controlled by the local environment in many oysters and scallops.” [Read more…]
