Publication number: 20250059709Abstract: The present invention provides a pulp product (e.g., paper) comprising cellulose and nanocellulose, wherein the nanocellulose is derived from the cellulose in a mechanical and/or chemical step that is separate from the main pulping process. The pulping process may be thermomechanical pulping or hydrothermal-mechanical pulping, for example. The pulp product is stronger and smoother with the presence of the nanocellulose. The nanocellulose further can function as a retention aid, for a step of forming the pulp product (e.g., in a paper machine). Other embodiments provide a corrugated medium pulp composition comprising cellulose pulp and nanocellulose, wherein the nanocellulose includes cellulose nanofibrils and/or cellulose nanocrystals and the nanocellulose may be hydrophobic. The nanocellulose improves the strength properties of the corrugated medium. In some embodiments, the cellulose pulp is a GreenBox+® pulp and the nanocellulose is derived from the AVAP® process.Type: ApplicationFiled: August 30, 2024Publication date: February 20, 2025Inventors: Theodora RETSINA, Kimberly NELSON, Lee HILL, Vesa PYLKKANEN, Timothy J.

Publication number: 20250043508Abstract: In some variations, OCC is screened, cleaned, deinked, and mechanically refined to generate cellulose nanofibrils. The OCC may be subjected to further chemical, physical, or thermal processing, prior to mechanical refining. For example, the OCC may be subjected to hot-water extraction, or fractionation with an acid catalyst, a solvent for lignin, and water. In certain embodiments to produce cellulose nanocrystals, OCC is exposed to AVAP® digestor conditions. The resulting pulp is optionally bleached and is mechanically refined to generate cellulose nanocrystals. In certain embodiments to produce cellulose nanofibrils, OCC is exposed to GreenBox+® digestor conditions. The resulting pulp is mechanically refined to generate cellulose nanofibrils. The site of a system to convert OCC to nanocellulose may be co-located with an existing OCC processing site. The nanocellulose line may be a bolt-on retrofit system to existing infrastructure.Type: ApplicationFiled: June 12, 2024Publication date: February 6, 2025Inventors: Kimberly NELSON, Theodora RETSINA, Lee HILL

Publication number: 20140239157Abstract: This invention relates to a low light imaging sensors and particularly image intensification and CMOS sensors. To overcome issues of dazzle and halo when operating in areas where the scene encompasses bright light sources, the invention provides material layers in contact with the detector material to spatially limit the generation or subsequent diffusion of electrons in said detector material. This allows the imaging sensor to perform as normal under bright conditions, maintaining the operator's scene awareness and spatial acuity.Type: ApplicationFiled: September 27, 2012Publication date: August 28, 2014Inventors: Christopher David Burgess, Lee Hill
