Cellulose Nanocrystal Application Research – Presented by Dr. Cagri Ayranci on May 11, 2016 @ Alberta Innovates Bio Solutions Impact Innovation 2016
Here is an excellent video on current cellulose nanocrystal application research presented by Dr. Cagri Aranci.
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 firstname.lastname@example.org.

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.
Implant materials: Reducing wear debris
ACS Nano, 2016, 10 (1), pp 298–306 – Ai Lin Chun – Nature Nanotechnology – Published 03 February 2016
Total joint replacements frequently fail because wear debris from the prosthesis, which is typically made of ultrahigh molecular weight polyethylene, can trigger an immune response. To prevent this, scientists formed a composite of polyethylene and cellulose nanocrystals as a strengthener to increase the wear resistance to minimize the wear debris.

nn-2015-04393k_0011Abstract – The doping of biocompatible nanomaterials into ultrahigh molecular weight polyethylene (UHMWPE) to improve the biocompatibility and reduce the wear debris is of great significance to prolonging implantation time of UHMWPE as the bearing material for artificial joints. This study shows that UHMWPE can form a composite with nanocrystalline cellulose (NCC, a hydrophilic nanosized material with a high aspect ratio) by ball-milling and hot-pressing. Compared to pure UHMWPE, the NCC/UHMWPE composite exhibits improved tribological characteristics with reduced generation of wear debris. The underlying mechanism is related to the weak binding between hydrophilic NCC and hydrophobic UHMWPE. The hydrophilic, rigid NCC particles tend to detach from the UHMWPE surface during friction, which could move with the rubbing surface, serve as a thin lubricant layer, and protect the UHMWPE substrate from abrasion. The biological safety of the NCC/UHMWPE composite, as tested by MC3T3-E1 preosteoblast cells and macrophage RAW264.7 cells, is high, with significantly lower inflammatory responses/cytotoxicity than pure UHMWPE. The NCC/UHMWPE composite therefore could be a promising alternative to the current UHMWPE for bearing applications.
Here is a recorded Tappi webinar, produced in May 2013 where Sean Ireland does a great job of introducing nanocellulose, the different types, how they are made and the potential market applications that exist.
