MONODISPERS NiO NANOKLASTERLARINING AGREGATSIYA MEXANIZMLARI
##submission.downloads##
Turli muhitlarda nanokatalizatorlar o‘lchamini boshqarishda ularning muhitdagi agregatsiya mexanizmlarini o‘rganish fundamental ahamiyatga ega. Garchi NiO nanozarralar agregatsiya jarayonlari ideal muhitlarda (ya’ni, gaz va suvli eritmalarda) qisman o‘rganilgan bo‘lsada, ularning suvli muhit bilan ta’sir mexanizmlari haligacha to‘la tushinilmagan. Ushbu tadqiqotda o‘lchami 1 nm atrofidagi NiO nanoklasterlari agregatsiya jarayoniga muhitning ta’siri molekulyar dinamika usuli yordamida o‘rganildi. Hisoblash natijalari shuni ko‘rsatadiki, (1) suvli muhit ta’sirida NiO nanoagregatlari atrofida hosil bo‘lgan
Natural sciences gidrodinamik qobiq (qalinligi 0.08 nm) hisobiga bu nanoagregatlar vakuumdagiga nisbatan bir-biridan uzoqroq masofada joylashadi, hamda (2) bu gidrodinamik qobiqning hosil bo‘lishi natijasida NiO nanoklasterlari suv muhitidagi barqarorligi pasayadi. Ushbu tadqiqot nanotexnalogiyaning asosini tashkil qilgan noyob fizik xususiyatli nanomateriallarning selektiv sintezi uchun nanokatalizatorlar o‘lchamini boshqarishni yaxshiroq tushunishda yordam beradi.
