CVS, a well-known drugstore chain in the United States, primarily focuses on health and wellness products, beauty items, medications, and convenience goods. While it's best known for its pharmacy services, CVS does offer a variety of office and school supplies. However, the selection of such items, including printer ink, can vary greatly from one CVS store to another. Some locations might carry a limited selection of ink cartridges, particularly those for common printer models, but CVS is not typically recognized as a go-to retailer for printer ink. If you're in urgent need of ink, it might be worth calling your local CVS to check their current stock. For a broader selection, specialized electronic or office supply stores are generally more reliable options.
Sunlight can degrade polymers through the process known as photo-oxidation, which involves the absorption of ultraviolet (UV) light by the polymer chains. This absorption of energy can break the chemical bonds within the polymer structure, leading to the formation of free radicals. These free radicals can react with oxygen present in the environment, resulting in the deterioration of the polymer's properties, such as changes in color, loss of tensile strength, and brittleness. The rate of degradation is influenced by the type of polymer, presence of UV stabilizers or absorbers, and environmental conditions. To mitigate these effects and extend the lifespan of polymers exposed to sunlight, stabilizers such as UV absorbers, quenchers, or HALS (Hindered Amine Light Stabilizers) are commonly added during the manufacturing process.

Boron carbide is a ceramic material, specifically a type of non-metallic, inorganic solid. It is renowned for its exceptional hardness, coming in just behind diamond and cubic boron nitride in terms of hardness scale. Structurally, it's made up of boron and carbon atoms, which forms a very rigid crystalline lattice. This makes it highly resistant to abrasion and thus, it's often used in applications requiring wear resistance, such as in abrasive nozzles, body armor, and cutting tools. Unlike metals, which have free electrons that facilitate electrical conductivity, or polymers, which are composed of long chains of organic molecules, ceramics like boron carbide are characterized by strong ionic and covalent bonds which contribute to their high hardness, high melting point, and generally poor conductivity.
