In 1791. Rev. William Gregor made a remarkable discovery in Cornwall: black magnetic sand resembling gunpowder. This sand. known as ilmenite. turned out to contain an unknown metal. Four years later in 1795. German scientist Martin Heinrich Klaproth identified this metal as titanium and gave it a name inspired by the Greek mythological figure Titan. son of the earth.
Polyethylene Terephthalate (PET) is a type of polyester derived from reacting ethylene glycol (EG) with terephthalic acid (TPA), or its dimethyl ester, dimethyl terephthalate (DMT). This reaction is known as polycondensation. Ethylene glycol is an organic compound commonly used as an antifreeze and in the manufacture of polyester fibers and resins, while terephthalic acid is a benzene derivative. PET is famed for its strength, durability, and recyclability, making it a preferred material for various applications, including fibers for clothing, containers for liquids and foods, and engineering resins used in combination with glass fiber for high-performance applications. Its widespread use in the packaging industry is attributed to its strong barrier properties against water vapor and gases, which help in preserving the freshness of packaged goods. PET's lightweight nature also contributes to reducing transportation costs and carbon emissions, underlining its value in sustainable manufacturing and consumption practices.

[In inkjet printers, the color ink cartridges typically run out faster than black ink, especially in environments where color printing is frequent, such as printing graphics or photos. This discrepancy arises because color printing requires the combined use of cyan, magenta, and yellow inks to produce the wide range of colors desired. In contrast, black ink is used exclusively for monochrome documents, which are more common in office settings but require less ink per page than color prints. Additionally, the printer's color management system may consume small amounts of color ink even when printing in grayscale to maintain color balance and print quality, further depleting color ink levels. Manufacturers recommend using genuine cartridges for optimal efficiency and to avoid unnecessary waste. Meanwhile, users looking to conserve ink might consider adjusting their printer settings to print in draft mode for non-final documents or use grayscale printing when color is not necessary.]
