Liquefied wood coating
Disclosed are various embodiments relating to a liquefied wood coating that can be applied to virtually any surface. The liquefied wood coating contains a micronized wood powder, a non-elastomeric resin with high adhesion properties, and an elastomeric resin for flexibility. Once dried, the wood coating accepts stain, polyurethane, and other types of coatings to provide a real wood finish.
Lignin derived photo-responsive coatings
Coating compositions that provide hydrophilic and self-cleaning properties upon exposure to an electromagnetic spectrum are disclosed. Coatings can include lignin-coumarate derivatives and/or lignin-azobenzene derivatives. When exposed to the electromagnetic spectrum, these compounds isomerize to cis-configuration which are hydrophilic in nature as compared to when these compounds are in their hydrophobic trans-state.
Compositions of biomass materials for refining
The present invention relates to a composition and a method for preparing said composition where the composition comprises a lignin, a solvent, a carrier liquid, and a fatty acid, wherein the lignin constitutes at least 4 weight % of the composition and has a weight average molecular weight of not more than 5,000 g/mol, wherein the solvent is an alcohol, ether, organic ester, sulfoxide, ketone, aldehyde or a combination thereof, and wherein the carrier liquid is a hydrocarbon oil.
Methods for making hydrophobizing compositions by hydrodynamic cavitation and uses thereof
Methods for making emulsified hydrophobizing compositions and uses thereof are provided. In at least one specific embodiment, a method for making an emulsified hydrophobizing composition, can include mixing a hydrophobizing agent, a liquid medium, and a lignosulfonic acid or salt thereof to provide a hydrophobizing composition and emulsifying the hydrophobizing composition using hydrodynamic cavitation to provide an emulsified hydrophobizing composition. The emulsified hydrophobizing composition can have an average particle size of about 0.3 microns to about 160 microns. The method can also include maintaining the emulsified hydrophobizing composition at a temperature of greater than a melting point of the hydrophobizing agent for at least 10 minutes.
ELECTRODE ACTIVE COATING FOR A LITHIUM-ION BATTERY AND METHOD OF PRODUCTION THEREFORE
A method for producing an electrode active coating on a current collector comprising providing isolated lignin and subjecting the isolated lignin to a pre-treatment in order to remove low molecular mass fractions of the lignin. The pre-treated lignin is mixed with an electrode active material, water and a conductive additive material so as obtain a slurry adapted for coating of a current collector. The coating obtained by the method comprises pre-treated lignin as a binder. The coating obtained has good binding properties between the particles of the coating as well as to the current collector. Furthermore, it has excellent electrochemical properties during use in a lithium-ion battery.
Functionalized lignin and method of producing the same
In this study, commercially available softwood lignin was esterified with tall oil fatty acid (TOFA) and tested as barrier material in fiber-based packaging material. The modified lignin samples were applied with a bar coater forming an even coating on the paperboard substrate. A significant decrease in WVTR and OTR value was observed for paperboard coated with the modified lignin as well as pure TOFA used as a reference. In contrast to the TOFA coating, the modified lignin coatings exhibited a high and stable contact angle. The coating material did not affect the tensile strength of the paperboard. According to the results, the demonstration of the conversion of lignin into a value added product has been shown. Furthermore, the novel coating material shows promising properties for the development as sustainable barrier material in fiber-based packaging material to replace oil-placed barriers.
PRODUCTION OF HUMIC ACID BASED POWDERS FOR LATENT FINGERPRINT DETECTION
The invention comprises the production and use of humic acid and its various salts (humate), which have been used even in areas such as food, pharmaceutical, etc., as fingerprint powder, alternatively to fingerprint powders with various compositions used for fingerprint detection, the oldest and most common method for criminal identification at crime scenes.

BIODEGRADABLE FUNCTIONAL BIOBASED COATING
A biobased coating and method of forming and use of the same is disclosed. The biobased coating can be used, for example, in packaging and food receptacles or as a sacrificial layer. The coating includes (a) a cellulose, (b) lignin and/or (c) natural latex. Since the coating does not use wax or petrochemically derived polymers, it is eco-friendly to produce and biodegradable. The biobased coating can be formed on an external surface of a substrate, such as, e.g., paper or pulp starch, corrugated cardboard, mushroom (including mycelium), seaweed, a fabric, concrete or metal.
Containment with internal seal and method for manufacture thereof
The present disclosure concerns a containment of pulp material that reduces reliance on adhesives and polymers. The containment is of two preformed semi-cylinders that linked together by using a preformed raised ridge that slots into a trough on the opposing half. The containment may optionally include a biopolymer based internal layer to provide a sealed containment. The present disclosure also concerns a cap for the containment with a narrowed wall and a recess to retain a lid liner with notched walls that allow for expansion at the closed end.
