Onye ọzọ nwetara ihe nrite Nobel nke ekwesịrị ka a kpọtụrụ aha tupu ya alaghachi na ọmụmụ ihe ugbu a bụ Johannes Diderik van der Waals, onye nwetara Nrite Nobel na Physics kpọmkwem otu narị afọ tupu mgbe ahụ, na 1910. Ihe ndị a kpọrọ aha ugbu a n'aha ya—vdW material—bụ ihe a na-elekwasị anya na ya. Nchọpụta Prof. Kaminer.Graphene bụkwa ihe atụ nke ihe vdW, mana nchọpụta ọhụrụ ahụ na-achọpụta ugbu a na ihe vdW ndị ọzọ dị elu bara uru maka ịmepụta X-ray.Ndị na-eme nchọpụta Technion ewepụtala ihe vdW dị iche iche wee ziga ọkụ elektrọn site na ha n'akụkụ ụfọdụ nke butere mpụta X-ray n'ụzọ ziri ezi.Ọzọkwa, ndị nchọpụta ahụ gosipụtara ngbanwe ziri ezi nke ụdị ọkụ ọkụ radieshon na mkpebi a na-enwetụbeghị ụdị ya, na-eji mgbanwe n'ichepụta ezinụlọ nke ihe vdW.
