“…In [1], it was reported on the Rochelle salt ferroelectric phase stabilization in porous alumina up to the decomposition temperature (328 K), which is about 30 K higher than the upper phase transition temperature in bulk samples. An increase in the phase transition temperature was also observed for sodium nitrite, triglycine sulfate, and thiourea encapsulated in porous alumina [2][3][4][5].…”

“…Properties of small particles in pores can change significantly in comparison with properties of bulk materials due to size effects, the interaction with pore walls, and the interparticle interaction. Ferroelectric nanostructures based on porous matrices were studied, e.g., in [1][2][3][4][5][6]. In [1], it was reported on the Rochelle salt ferroelectric phase stabilization in porous alumina up to the decomposition temperature (328 K), which is about 30 K higher than the upper phase transition temperature in bulk samples.…”

“…Свойства малых частиц в порах могут значительно изменяться по сравнению со свойствами объемных веществ за счет размерных эффектов, взаимодействия со стенками пор и межчастичного взаимодействия. Исследования сегнетоэлектрических наноструктур, полученных на основе пористых матриц, были проведены, например в [1][2][3][4][5][6]. В [1] сообщалось о стабилизации сегнетоэлектрической фазы сегнетовой соли в пористом оксиде алюминия вплоть до температуры разложения (328 K), которая примерно на 30 K выше температуры верхнего фазового перехода объемных образцов.…”

Повышение температуры фазовых переходов наблюдалось также для нитрита натрия, триглицинсульфата и тиомочевины, внедренных в пористый оксид алюминия [2][3][4][5]. В то время как для LiCsSO 4 в порах силикатных матриц MCM-41 (d ∼ 3.7 nm) фазовый переход смещался в область более низких температур примерно на 6 K по сравнению с объемным LiCsSO 4 [6].…”

“…Depending on preparation technique, the pore diameter of Al 2 O 3 film varies from 20 to 400 nm with a density of 10 8 -10 12 pores cm −2 . Studies on properties of ferroelectric nanostructures obtained from nanoporous Al 2 O 3 were carried out as reported in numerous works [5][6][7][8][9][10]. The authors of [5] reported the stabilization of ferroelectric phase in Rochelle salt embedded into Al 2 O 3 pores up to the decomposition temperature (328 K) i.e.…”
