This invention provides particle board or fiber board that is 100% non-toxic and 25% stronger than currently available products. This is accomplished by replacing commonly used formaldehyde based resins with a safe, renewable nanocellulose based binder.
- Reduction of health problems and related expenses ($9m – $48m per year1) caused by formaldehyde exposure
- 25% strength increase reduces material and transportation costs
- Nanocellulose, a renewable resource, replaces binders generally synthesized from non-renewable resources
Performance quality of many industrial materials depends on consistent distribution of particle sizes within the material. The ability to quantify other parameters such as surface roughness, surface area, and particle shape is also desirable. Current methods provide a static, batched measurement of limited utility. This new method and device provides real-time measurements directly from the manufacturing line flow.
This device has demonstrated performance on paper additive products with aspect ratios ranging from 2 to 8 and short axis diameters between 100 and 500 nm. Applications are in quality control.
A stable, aqueous barrier coating composition includes: (a) prolamine; (b) cold water insoluble polymer; (c) water; (d) water-soluble co-solvent; and (e) stabilizer. The composition, when applied to a substrate, produces an article having a high surface energy and resistance to oil and grease penetration. A method of producing the article involves applying the composition to a substrate.

Environmentally Friendly Adhesive Bonding for Composites, Pollutant Remediation, and Dye Decolorization
PROBLEM: Environmentally friendly methods are needed to bond wood products and other composites without formaldehyde. Organic pollutants and dyes from textile and paper plants in industrial wastestreams need remediation.
SOLUTION: Using the chemically enhanced Fenton system, dyes can be remediated quickly in an environmentally safe manner. Natural lignin from wood residues can be activated to produce an formaldehyde-free adhesive system and organic pollutants in waters or soils can be broken down.
