Abrégé
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.

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.

Abrégé
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.

Abrégé
Structural hierarchy in heat sinks combines the thermal conductivity of materials with fin architectures tailored for active or passive electronic cooling components. Heat sinks with nanoscale hierarchical structures can combine thermally conductive materials with high aspect-ratio fms for rapid thermal exchange with surroundings. Carbon nanotubes (CNT) are promising components since they combine ultra-high thermal conductivity along their axial directions with high surface area and radiative heat transfer capacity. In some embodiments, nanostructures (e.g., aligned carbon nanotubes) strongly attached (e.g., covalently attached) to surfaces of structures such as heat sinks, heat spreaders, etc., can enhance thermal performance (e.g., thermoelectric energy generation (TEG) voltage, heat dissipation, heat radiation, etc.).

The perception of flavor is a multisensory experience as it involves not only taste, but other sensory experiences such as sight, sound, smell, and touch. Delivery of one or more sensory experiences to a user as the user is consuming a food item is able to augment how the user experiences the food item's flavor. For example, changing a smell or color a food item has affects how users perceive it when being consumed. Changing perceptions through stimulating various senses can alter expectations significantly and in unexpected ways when delivering or combining stimuli. Accordingly in some embodiments, the present disclosure provides for technologies (e.g., device(s), systems and/or method(s)) for delivering simulated flavor sensations while consuming food items (e.g., solid food items, a beverage).
