Professor David Kisailus, from the University of California, Riverside’s Bourns College of Engineering, together with his team of students and scientists at Harvard University, University in Cambridge Mass., Chapman University in Orange, Calif. and Brookhaven National Laboratory in Upton, NY, designed the revolutionary engineering products and materials.

have been of interest to Kisailus for about five years. Initially he was interested in abrasion and impact-resistant materials. Some of his earlier findings indicate that chiton teeth contain magnetite- the hardest biomaterial known on Earth.

The professor used his previous knowledge and built on it to come up with his ground-breaking innovation. The aim of his work was to determine the exact process of formation of the magnetic region of the chiton’s teeth.

This research identified three crucial steps in the formation of the material. Firstly, hydrated iron oxide (ferrihydrite) crystals nucleate on a fiber-like chitinous (complex sugar) organic template. Through the process of solid-state transformation, ferrihydrite particles convert to a magnetic iron oxide (magnetite). The strength of the teeth comes from the yielding of parallel rods within the teeth, which occurs as a result of the organic fibers growing along the magnetite particles.

This process occurs at a room temperature, naturally bringing down the production cost of the nanomaterials. This is the procedure Kisailus follows in order to grow minerals used in solar cells and lithium-ion batteries under laboratory conditions.

He is convinced that building such materials is possible and they will help solar cells and lithium-ion batteries operate more efficiently.

Paper battery?

WASHINGTON (Reuters) – Ordinary paper could one day be used as a lightweight battery to power the devices that are now enabling the printed word to be eclipsed by e-mail, e-books and online news.
Scientists at Stanford University in California reported on Monday they have successfully turned paper coated with ink made of silver and carbon nanomaterials into a "paper battery" that holds promise for new types of lightweight, high-performance energy storage.
The same feature that helps ink adhere to paper allows it to hold onto the single-walled carbon nanotubes and silver nanowire films

“We are looking for solid materials that can store and release hydrogen easily,” said Olivia Graeve, a professor at the Jacobs School of Engineering at UC San Diego, who has gained international recognition as a nanomaterials manufacturing expert.
