Nanocellulose Video

Here is an excellent 4-minute video produced by TAPPI.  It has been around for a while, but it is still very relevant.

The video is focused on the forestry industry, but nanocellulose can be extracted from any  lignocellulosic biomass.  This would include trees, wheat straw, rice straw, hemp, flax, bamboo, sisal, corn stover and miscanthus to name a few.

At Blue Goose, we focus our efforts on producing cellulose nanocrystals, a specific type of nanocellulose, sometimes referred to as nanocrystalline cellulose, crystalline nanocellulose, cellulose whiskers or cellulose nanowhiskers.

Blue Goose provides companies, universities, and individuals easy access to this exciting new material for research and product development activities without any intellectual property restrictions.

We welcome guest posts or specific questions directed to info@bluegoosebiorefineries.com.

Food additive

Nanocellulose as a Food Additive

salad-drinkCellulose nanofibers (CNF) as well as cellulose nanocrystals (CNC) are being investigated by a number of research laboratories including Innventia (Sweden) and Borregaard (Norway), among others. Nanocellulose shows promise as a stabilizer for oils in water emulsions and foams containing high amounts of dissolved sugar. When added to dough, nanocellulose makes bread with higher volume and even form. Nanocellulose has also been added to hamburger to improve the moister retention during frying.

Lastly, nanocellulose from coconuts has been commercialized as a low-calorie, high dietary fiber additive in fruit flavored drinks by a number of companies in the far east. The nanocellulose product is called nata de coco. Nata de coco can also be enjoyed as a mixture of iced fruit, compote, custard, ice cream, fruit cocktail, candy, or desert.

Cellulose Nanogenerators

How Cellulose Nanogenerators Power Bio-Implants
Calendar February 1, 2016

Implantable electronics that can deliver drugs, monitor vital signs and perform other health-related roles are on the horizon. But finding a way to power them remains a challenge. Now scientists have built a flexible nanogenerator out of cellulose, an abundant natural material, that could potentially harvest energy from the body — its heartbeats, blood flow and other almost imperceptible but constant movements.

Efforts to convert the energy of motion — from footsteps, ocean waves, wind and other movement sources — are well underway. Many of these developing technologies are designed with the goal of powering everyday gadgets and even buildings. As such, they don’t need to bend and are often made with stiff materials. But to power biomedical devices inside the body, a flexible generator could provide more versatility. So Md. Mehebub Alam and Dipankar Mandal at Jadavpur University in India set out to design one.

The researchers turned to cellulose, the most abundant biopolymer on earth, and mixed it in a simple process with a kind of silicone called polydimethylsiloxane — the stuff of breast implants — and carbon nanotubes. Repeated pressing on the resulting nanogenerator lit up about two dozen LEDs instantly. It also charged capacitors that powered a portable LCD, a calculator and a wrist watch. And because cellulose is non-toxic, the researchers say the device could potentially be implanted in the body and harvest its internal stretches, vibrations and other movements.

The findings appear in the journal ACS Applied Materials & Interfaces.
