Aerospace nanotechnology refers to the application of nanotechnology science and engineering conducted at the scale of atoms and molecules (typically below 100 nanometers) to the design, development, and performance enhancement of aerospace systems, including aircraft, spacecraft, satellites, and unmanned aerial vehicles (UAVs). This field involves the use of nanomaterials, nano sensors, nanoelectronics, and nanostructures to improve key aerospace characteristics such as strength-to-weight ratio, thermal resistance, durability, fuel efficiency, stealth capabilities, and system miniaturization.

In glass recycling, waste glasses are crushed and melted to cullet. Cullet is a high-grade product that is mixed with virgin materials such as sand and limestone for manufacturing new glass bottles and containers. This cullet can be further categorized into internal and external cullet based on the feedstock used for manufacturing. The internal cullet is manufactured by crushing defective glass products such as bottles, which are rejected during a quality check at various manufacturing industries. The external cullet is manufactured by the processing of used bottles or other glass. Glass fines are low-grade products, which are used in the manufacturing mix of construction and car glass.

Cosmetics are naturally sourced or chemically synthesized products that are designed to improve or enhance the physical appearance. These improvements and enhancements may be achieved through various properties such as body cleansing, skin protection, skin nourishment, hair conditioning, and moisturizing. Cosmetic ingredients are naturally available or synthetically developed; common cosmetic ingredients include water, emulsification agents, preservatives, thickeners, moisturizers, colorants, and fragrances.

A glass lens is a transparent optical component used in glasses (eyewear) to correct vision or protect the eyes. These lenses can be made from various materials, including glass, plastic, or polycarbonate, and are designed to focus light correctly onto the retina, helping to improve vision clarity.

Agricultural films encompass stretchable plastics used to protect crops in open fields and greenhouses, enhancing productivity and crop quality. These films are made from materials like polyethylene and ethyl vinyl acetate, and are used in applications such as mulching, silage, and greenhouse covering.
