Charles-Saint-Ange Thilorier was a student at the École polytechnique in the class / year of 1815, who was mistakenly believed to have been the first person to create solid carbon dioxide ("dry ice"). Actually, a French inventor, Adrien-Jean-Pierre Thilorier (1790–1844), discovered dry ice.
Dry ice blasting used for cleaning a rubber mold Dry ice blasting used for cleaning electrical installations. Dry ice can be used for loosening asphalt floor tiles or car sound deadening material, making them easy to prise off, [30] as well as freezing water in valveless pipes to enable repair. [31]
c. 50,000 BC – A discovered twisted fibre (a 3-ply cord fragment) indicates the likely use of clothing, bags, nets and similar technology by Neanderthals in southeastern France. [1] [2] c. 27000 BC – Impressions of textiles and basketry and nets left on small pieces of hard clay in Europe. [3] c. 25000 BC – Venus figurines depicted with ...
Fibers invented between 1930 and 1970 include nylon, PTFE, polyester, Spandex, and Kevlar. Clothing producers soon adopted synthetic fibers, often using blends of different fibers for optimized properties. [100] Synthetic fibers can be knit and woven similarly to natural fibers. Synthetic fibers are made by humans through chemical synthesis as ...
c. 1700 BC – Zimri-Lim, ruler of Mari in Syria commanded the construction of one of the first ice houses near the Euphrates. [2] c. 500 BC – The yakhchal (meaning "ice pit" in Persian) is an ancient Persian type of refrigerator. The structure was formed from a mortar resistant to heat transmission, in the shape of a dome.
A vacuum is the best insulator, but its use in clothing is impractical. Dry air is a practical insulator. Extreme cold weather clothing uses still dry air to insulate the body, [2] layers of loose air trapping material are most effective. The inner layers should conduct moisture away from the body.
Radiative cooling has been applied in various contexts throughout human history, including ice making in India and Iran, [3] heat shields for spacecraft, [4] and in architecture. [5] In 2014, a scientific breakthrough in the use of photonic metamaterials made daytime radiative cooling possible.
