Selectively depolymerizing cellulosic materials for use as thermal and acoustic insulators
The present invention relates to the creation of thermally insulating materials derived from cellulosic materials by selectively depolymerizing the materials anatomy. Cellulosic materials may be comprised of three main biopolymers: lignin, hemicellulose, and cellulose. The present invention relates to the chemical and physical removal of lignin and hemicellulose, while leaving the cellulose unaltered to induce increased porosity within the material and the material's macrostructure matrix for use as thermal and acoustic insulation. The increased porosity will be due to the creation of closed cell voids within the cellulosic matrix. These voids will increase the thermal and acoustic insulating performance of the cellulosic materials. The selective removal of secondary biopolymers from cellulosic materials allow for isolation of other value added products that can be regenerated through fewer reactions/steps. This is a novel advantage over other similar processes that dissolve cellulose completely, making it harder to extract and isolate secondary off-stream products.
STRONG AND TOUGH STRUCTURAL WOOD MATERIALS, AND METHODS FOR FABRICATING AND USE THEREOF
A super strong and tough densified wood structure is formed by subjecting a cellulose-based natural wood material to a chemical treatment that partially removes lignin therefrom. The treated wood retains lumina of the natural wood, with cellulose nanofibers of cell walls being aligned. The treated wood is then pressed in a direction crossing the direction in which the lumina extend, such that the lumina collapse and any residual fluid within the wood is removed. As a result, the cell walls become entangled and hydrogen bonds are formed between adjacent cellulose nanofibers, thereby improving the strength and toughness of the wood among other mechanical properties. By further modifying, manipulating, or machining the densified wood, it can be adapted to various applications.
Integrated unit for treatment and drying lignocellulosic material
An integrated boiler-dryer consisting in a sealable vessel capable of sustaining high humidity and variable gas pressures and into which is placed a lignocellulosic material, and a compound in mist form. The sealable vessel provides dry heat so as to dry the lignocellulosic material while the compound is impregnated within the lignocellulosic material.

FRAGRANCE DISPENSING EMANATING SUBSTRATE AND METHOD
The present disclosure relates to the field of perfumery. In particular, the present disclosure provides fragrance dispensing emanating substrate and related methods for dispensing fragrance oil or liquid fragrance material into an ambient environment.
Wood transaction instrument
In some examples, a method of manufacturing a densified wood transaction instrument includes boiling a sheet of wood in a chemical solution, compressing the boiled sheet of wood using a die in a press to form one or more features in the sheet of wood, during the compressing of the boiled sheet of wood, heating the boiled sheet of wood to create a sheet of densified wood, and attaching one or more payment elements to at least one of the one or more features formed in the sheet of densified wood to form a sheet of one or more densified wood transaction instruments.

Rotary Separation Apparatus and Process of Use
A rotary separation devise deploys a drum with mesh like opening on the cylindrical surfaces and a removable cover or cap for filling in an upright position and removal of product or spent matter in an inverted position. When the drum is loaded with material, and the cover closed, it is rotatable to a horizontal position, and disposed in an outer container. The drum is rotated in the horizontal position to initiate the separation process. The outer container may be formed by the mating engagement at a common rim of an upper and lower vessel that form the sealed container.
