\nNept\u00fcn ve Uran\u00fcs gibi buz devi gezegenler, \u00e7al\u0131\u015fmay\u0131 yay\u0131nlayan ekibin laboratuvarda ortaya \u00e7\u0131kard\u0131\u011f\u0131 ortama benzer fiziksel ko\u015fullar\u0131 sa\u011fl\u0131yor. Bu durum da, bu gezegenlerin merkezi noktalar\u0131nda k\u00fc\u00e7\u00fck elmas zerreciklerinin olabilece\u011fini ortaya koyuyor. Dahas\u0131, bu yeni uygulama kuantum teknolojileri kullanan cihazlarda ihtiya\u00e7 duyulan nanoelmas \u00fcretiminde kullan\u0131labilir.<\/p>\n

\nYay\u0131mlanan yeni \u00e7al\u0131\u015fmada ara\u015ft\u0131rmac\u0131lar lazerleri ilk \u00f6nce \u00e7e\u015fitli plastik \u00f6rnekleri kullanarak “e\u011fittiler”. Ate\u015flenen her lazer bir \u015fok dalgas\u0131, plasti\u011fin i\u00e7inden ge\u00e7en bir \u015fok dalgas\u0131 \u00fcretiyor ve plasti\u011fin y\u00fczeyindeki bas\u0131n\u00e7la s\u0131cakl\u0131\u011f\u0131 y\u00fckseltiyor. Malzemeyi X-\u0131\u015f\u0131n\u0131 ate\u015flemeleriyle saran bu s\u00fcre\u00e7\u00a0 nanoelmaslar\u0131n olu\u015fmas\u0131n\u0131 sa\u011fl\u0131yor.
\nDaha \u00f6nce yap\u0131lan \u00e7al\u0131\u015fmalarda Hidrojen ve Karbon atomlar\u0131n\u0131 s\u0131k\u0131\u015ft\u0131rarak elmas olu\u015fturmay\u0131 ba\u015farm\u0131\u015ft\u0131. Ancak \u00f6zellikle g\u00fcnl\u00fck hayatta s\u0131k\u00e7a kullan\u0131lan yiyecek ve i\u00e7ecek paketlerinin temel malzemesi PET, yaln\u0131zca Hidrojen ve Karbon de\u011fil ama ayn\u0131 zamanda Oksijen de i\u00e7eriyor. Bu kimyasal yap\u0131 buz devi olarak adland\u0131r\u0131lan Nept\u00fcn ve Uran\u00fcs i\u00e7erisinde de bulunmakta. Almanya’n\u0131n Rostock \u00dcniversitesi’nden biliminsan\u0131 Dominik Kraus, “Oksijen elmas olu\u015funa olduk\u00e7a elveri\u015fli bir malzeme gibi g\u00f6r\u00fcn\u00fcyor zira Oksijen Hidrojeni adeta ’emiyor’ ve geriye sadece elmas haline gelen Karbon kal\u0131yor.” diyor.
\nNanoelmaslar \u00f6zellikle patlay\u0131c\u0131 \u00fcretiminde kullan\u0131lmaktalar dolay\u0131s\u0131yla kontrol etmeleri kolay de\u011fil. Kraus ve ekibinin \u00f6nerdi\u011fi bu yeni teknik genel kullan\u0131ma \u00e7ok daha uygun bir nanoelmas \u00fcretim y\u00f6ntemi sunuyor. Ayr\u0131ca Azot kullan\u0131lan kimi kuantum cihazlar\u0131nda da bu y\u00f6ntem sayesinde Karbon kullan\u0131labilire benziyor.
\nABD’nin Kaliforniya eyaletinde\u00a0 bulunan Lawrence Livermore Ulusal Labarotuvar\u0131’ndan, \u00e7al\u0131\u015fmada yer almayan fizik\u00e7i Marius Millot son olarak ekliyor: “Fikir \u00e7ok haval\u0131. Elinizde bir plastik \u015fi\u015fe var. Lazerle ate\u015f ediyorsunuz ve elmas olu\u015fuyor. G\u00fcnl\u00fck hayatta kullan\u0131m olas\u0131l\u0131klar\u0131n\u0131 zaman g\u00f6sterecek.”<\/p>\n
