MAVZUSIDAGI МАGISTRLIK DISSERTATSIYASIGA
АNNOTATSIYA
Mavzuning dolzarbligi: XX asrdagi sanoatlashish darajasi ortishi bilan energiyalarga bo’lgan ehtiyoj oshib bormoqda. Energiya resurslariga bo‘lgan talab tarkibiy jihatdan o‘zgarmoqda, xususan uglevodorod resurslaridan qayta tiklanuvchi manbalarga o‘tishda vodorod energetikasini rivojlantirish dolzarb masalaga aylanmoqda. Bugungi kunda vodorod esa ekologik toza muqobil energiya manbasi sifatida ko’rilmoqda. Aksariyat mutaxassis va olimlarning qayd etishicha, vodorod sanoati kelajakdagi globallashgan iqtisodiyotning asosini tashkil etishi kutilmoqda. Vodorodni xavfsiz saqlash esa muammoli masalalardan biri bo’lib qolmoqda.
Tadqiqot ob'ekti: Tadqiqod obekti sifatida H₂O (suv) va C₃H₆O (atseton) olinadi.
Tadqiqotning maqsadi: Binar suyuqliklarda nisbatan past bosimda vodorodni saqlash mumkin. Tadqiqod maqsadi suv va atseton aralashmasini MD simulyatsiya jarayonini baholash va binar suyuqliklarni turli xil konsentratsiyasida dielektrik va sindirish ko’rsatkich xossalarini tadqiq qilish. Vodorodni saqlash mumkin bo’lgan optimal suv va atseton aralashmasini prognoz qilish va eng ko’p vodorod bog’li klatrat strukturalar xosil qiluvchi konsentratsiyasini topish.
Tadqiqot vazifalari: Tadqiqod vazifalari suv va atseton aralashmasini kompyuterda MD metodi yordamida simulatsiya jarayonini kuzatish. Aralashmaning dielektrik konstanta va sindirish ko’rsatkichining ortiqcha qiymatlarini hisoblab, vodorodni saqlash mumkin bo’lgan konsentratsiyani topish va tajriba natijalari bilan taqqoslash. Refraktometr yordamida turli konsentratsiyalarda sindirish korsatkichlarini aniqlash.
Tadqiqotining ilmiy yangiligi: Vodorod saqlash mumkin bo’lgan texnalogiyalarga qo’shimcha tarzda, suv va atseton aralashmasining mavjud modellari qo’llanilishini yanada kengroq tadqiq qilish. Vodorod energiyasini samarali va xavfsiz saqlashda suv va atsetonning yangi modelini topish.

“DIELECTRIC AND OPTICAL CHARACTERISTICS OF BINARY FLUIDS FORMING HETEROMOLECULAR STRUCTURES” ANNOTATION TO THE MASTER'S DISSERTATION ON THE TOPIC

Relevance of the topic: The need for energy is increasing with the increase in the level of industrialization in the twentieth century. The demand for energy resources is changing structurally, especially in the transition from hydrocarbon resources to renewable sources. Today, hydrogen is seen as an environmentally friendly alternative energy source. Most experts and scientists point out that the hydrogen industry is expected to form the basis of a future globalized economy. The safe storage of hydrogen remains a problem.
Object of research: H₂O (water) and C₃H₆O (acetone) as the object of study is obtained.
The aim of the study: Hydrogen can be stored in binary liquids at relatively low pressures. The aim of the study was to evaluate the MD simulation process of a mixture of water and acetone and to study the dielectric and refractive properties of binary fluids at different concentrations. Predict the optimal mix of water and acetone that can store hydrogen and find the concentration that forms the most hydrogen-dependent clathrate structures.
Research objectives: The research tasks were to observe the process of simulation of a mixture of water and acetone on a computer using the MD method. Calculate the excess concentration of the dielectric constant and the refractive index of the mixture, find the possible concentration of hydrogen and compare it with the experimental results. Determination of refractive indices at different concentrations using a refractometer.
Scientific novelty of the research: In addition to potential hydrogen storage technologies, further study of the application of existing models of water and acetone mixtures. Finding a new model of water and acetone in the efficient and safe storage of hydrogen energy.
