Peculiarities of Low-Temperature Behavior of Liquids Confined in Nanostructured Silicon-Based Material

Abstract: This study is devoted to the confinement effects on freezing and melting in electrochemical systems containing nanomaterial electrodes and liquid electrolytes. The melting of nanoparticles formed upon freezing of liquids confined in pores of disordered nanostructured n-type silicon has been studied by low-temperature differential scanning calorimetry. Experimental results obtained for deionized water, an aqueous solution of potassium sulfate, and n-decane are presented. A model is proposed for predicting the m… Show more

“…The properties of materials composed of a homogeneous matrix in which nanoparticles are confined depend on the composition of the solid matrix and the composition, shape, size and crystalline structure of the nanoparticles (Schmid, 2010;Roy et al, 2017). Due to the general interest in the useful properties of these nanocomposites for applications in nanotechnology, studies of the thermodynamic properties of nanoparticles became of growing interest (Li et al, 2017;Delgado-Callico et al, 2021;Bardushkin et al, 2020;Zhang et al, 2020). The optical, electrical, magnetic and mechanical properties of nanocomposites are closely related to the thermodynamic properties of the embedded nanoparticles (Haro-Poniatowski et al, 2005, 2007Jimenez de Castro et al, 2014).…”

“…При этом большое значение имеет эффект изменения температуры плавления/замерзания жидкостей, адсорбированных в мезопористых структурах. Указанный эффект, в частности, может оказывать влияние на низкотемпературное поведение электролитов в металл-ионных аккумуляторах и суперконденсаторах [8][9][10][11][12][13].…”

“…Ранее в работах [8,9,17] были представлены результаты прогнозирования физико-механических свойств водонасыщенных por-Si без учета слоя SiO 2 на поверхностях пор. В работах [18,19] показано, что учет слоя SiO 2 в указанных структурах позволяет уточнить прогнозируемые значения эффективных и локальных упругих характеристик вблизи точки фазового перехода лед -вода.…”
