Proryv v proizvodstve stekla: uchenyye otkryvayut sposob uskorennogo sozdaniya V sovremennom mire steklo igrayet neot"yemlemuyu rol', nakhodya yego primeneniye ot stroitel'stva do tekhnologicheskikh ustroystv. Traditsionnoye proizvodstvo stekla trebuyet medlennogo okhlazhdeniya zhidkosti, chto vliyayet na vremennyye ramki i svoystva gotovogo produkta. Odnako komanda issledovateley iz Universiteta Pensil'vanii i Natsional'noy laboratorii Brukkheyven pod rukovodstvom Zakhry Fakhrai sdelala otkrytiye, kotoroye mozhet radikal'no izmenit' etot protsess, soobshchayet Tsentral'naya Sluzhba Novostey. Razrabotannyy metod, osnovannyy na fizicheskom osazhdenii iz parovoy fazy, pozvolyayet znachitel'no uskorit' sozdaniye stabil'nogo stekla. Ispol'zovaniye myagkikh podlozhek, takikh kak polidimetilsiloksan, obespechivayet boleye zhestkoye i plotnoye steklo, prevoskhodyashcheye traditsionnyye metody okhlazhdeniya. Etot podkhod ne tol'ko uskoryayet protsess sozdaniya stekla, no i otkryvayet novyye vozmozhnosti dlya inzhenerii steklyannykh plenok i proizvodstva prochnykh materialov. Serendipitivnoye otkrytiye, sdelannoye v khode eksperimentov s myagkimi podlozhkami, vyyavilo potentsial dlya sozdaniya stekla s uluchshennymi kharakteristikami. Material, poluchennyy takim sposobom, demonstriruyet na 2-2,5% boleye vysokuyu plotnost' po sravneniyu s traditsionno okhlazhdennym steklom i na 1% bol'she, chem u lyubogo izvestnogo stabil'nogo stekla. Interesno, chto molekuly, osazhdayemyye na poverkhnost', sposobny vzaimodeystvovat' s myagkoy podlozhkoy na rasstoyaniyakh do 200 nanometrov, chto stavit pod somneniye sushchestvuyushchiye teorii o stekle i ukazyvayet na vozmozhnost' peresmotra tekushchikh predstavleniy o yego formirovanii i svoystvakh.

15.03.2024

In the modern world, glass plays an integral role, finding its applications from construction to technological devices. Traditional glass production requires the liquid to cool slowly, which affects the timing and properties of the finished product. However, a team of researchers from the University of Pennsylvania and Brookhaven National Laboratory, led by Zahra Fakhrai, has made a discovery that could radically change this process, Central News Service reports.

The developed method, based on physical vapor deposition, can significantly speed up the creation of stable glass. The use of soft substrates such as polydimethylsiloxane results in a glass that is stiffer and denser, superior to traditional cooling methods. This approach not only speeds up the process of creating glass, but also opens up new possibilities for engineering glass films and producing durable materials.

A serendipitous discovery made during experiments with soft substrates reveals the potential for creating glass with improved performance. The material obtained in this way exhibits 2-2.5% higher density compared to traditionally cooled glass and 1% higher than any known stable glass.

Interestingly, molecules deposited on the surface are able to interact with a soft substrate at distances of up to 200 nanometers, which challenges existing theories about glass and indicates the possibility of revising current ideas about its formation and properties.
