Abstract
Performance-based designs follow building codes that specify the desired goals of a building, allowing more flexibility and innovation. Although the current modular and manufactured methods offer fewer manufacturing steps and reduced waste compared to traditional construction, production of modular components requires use of multiple materials and machines, and the processes are not highly precise or repeatable. The present disclosure incorporates performance- based designs and advanced manufacturing methods to fabricate construction components and/or sub-components that are intended to be utilized in building structures. The components and/or sub-components are manufactured by single machines or work cells in controlled environments and are subsequently transported to the site where minimal work is involved for assembly. The performance-based designs are applied in the initial design, throughout the life, and at the end-of- life reuse plan of the components. The current disclosure enables mass customization, precision and repeatability, and use of recyclable and biobased materials.

Abstract
Substances that are suspended, dispersed, and/or dissolved in a liquid can be dried or concentrated to obtain dried or concentrated material. For example, cellulose nanofibrils (CNFs) are cellulose-based materials with nanoscale dimensions and desirable properties formed by treating macroscopic cellulose fibers to defibrillate them into a slurry or feedstock, followed by drying of the feedstock to form dry CNF material. Drying methods such as spray drying and oven drying cause excessive aggregation of the dried materials, while freeze drying and supercritical CO2 drying are costly and difficult to scale up. The present embodiments include methods and systems using high shear for drying or concentrating liquid feedstocks containing suspended and/or dissolved substances to produce dried or concentrated substances in a scalable manner with high yield.

Abstract
Presented herein are systems and methods related to associating nanobubbles (NBs) with a composition (e.g., a liquid composition). NBs are ultrafine gas domains in liquid with nano-scale diameters that are, on average, smaller than 1000 nm diameter (e.g., about 200nm in diameter or less). NBs have remarkably large interfacial surface areas and have unique physicochemical properties due to their small dimensions. The small size (e.g., diameter) and higher surface tension of NBs increase the interfacial gas-liquid surface area, which in turn promotes mass transfer. In some embodiments, NBs (e.g., oxygen NBs) can be suspended in a composition (e.g., water) long periods of time and produce reactive oxygen species without added catalysts. However, NB applications in water treatment applications have not been widely explored.

Abstract
Presented herein are devices, systems, and methods related to liquid infused substrates for use in medical applications. Adhesion of proteins, pathogens, and other substances to medical devices presents an issue. Proteins from the surrounding environment adhere to medical devices, which may, under certain conditions, result in the adhesion of pathogens to the medical device. The presence of these pathogens may result in infections when a medical device is inserted or otherwise placed in vivo (in whole or in part), which may require the removal of the device and/or treatment of the subject with antibiotics.

Abstract
Presented herein are devices, systems, and methods related to liquid infused substrates for use in medical applications. Adhesion of proteins, pathogens, and other substances to medical devices presents an issue. Proteins from the surrounding environment adhere to medical devices, which may, under certain conditions, result in the adhesion of pathogens to the medical device. The presence of these pathogens may result in infections when a medical device is inserted or otherwise placed in vivo (in whole or in part), which may require the removal of the device and/or treatment of the subject with antibiotics. Changing the surface properties of such devices can alter which proteins, pathogens, and/or other substances adhere and/or adsorb to the surface. Accordingly, in some embodiments, the present disclosure provides for technologies for altering surface adhesion and/or absorption of proteins, pathogens and/or other substances by infusing/impregnating a substrate of the device with an impregnation fluid.

Abstract
An improved market pulp and process for making the same by adding a composite material are described. The composite material includes cellulose nanocrystals, cellulose nanofibers, or another high aspect ratio, high surface area cellulose material (or a starch, or both) and a crosslinking compound that crosslinks a portion of the surface hydroxyl groups to form a 3-D matrix. Adding the composite material to market pulp has been shown to improve the strength of twice-dried paper products, made from such an enhanced market pulp. By crosslinking a portion of the surface hydroxyl groups in the market pulp to form a 3-D matrix, a first drying step may be accomplished without loss of benefits afforded when the market pulp is later re-pulped to make a paper product.

Abstract
Lignin formulations for making light-selective mulch, methods of making such lignin formulations, light-selective mulches comprising substrates treated with lignin formulations, and methods of making such light-selective mulches. Some methods involve preparing aqueous lignin formulations that can be used as coatings that, in turn, can be applied to a substrate, such as a paper web, to form a biodegradable, light-selective mulch. Some such mulches blocks at least some light in the ultraviolet and blue/green ranges (350 nm to 500 nm) of the visible light spectrum to inhibit weed growth below the mulch, while also transmitting light in the red/infrared ranges to heat the soil below the mulch.

Abstract
An improved market pulp and process for making the same by adding a composite material are described. The composite material includes cellulose nanocrystals, cellulose nanofibers, or another high aspect ratio, high surface area cellulose material (or a starch, or both) and a crosslinking compound that crosslinks a portion of the surface hydroxyl groups to form a 3-D matrix. Adding the composite material to market pulp has been shown to improve the strength of twice-dried paper products, made from such an enhanced market pulp. By crosslinking a portion of the surface hydroxyl groups in the market pulp to form a 3-D matrix, a first drying step may be accomplished without loss of benefits afforded when the market pulp is later re-pulped to make a paper product.
