Thermal transformations in nanodimensional Pb—WO3 systems

Kinetic regularities of thermal transformations in nanosized lead films

“…The samples were prepared for studies by deposit ing thin (2-115 nm) lead films on glass substrates by thermal evaporation in vacuum (2 × 10 -3 Pa) using a VUP 5M vacuum system [24][25][26]. The substrates were glass photo plates (State Standard GOST 9284 59), which were preliminarily treated in concentrated nitric acid, potassium dichromate solution, concen trated sulfuric acid, and boiling surfactant solution; washed in distilled water; and dried [24][25][26].…”

The treated substrates were optically transparent in the range 300-1100 nm.…”

Thermal transformations in In-MoO3 nanofilms

“…Fundamental aspects of processes in heterogeneous systems are of interest for solid state physics and chem istry in many respects [1][2][3][4][5][6][7][8][9][10][11]. Studies of heterogeneous nanosystems are of technological importance and can be useful in gaining insight into the mechanism of solid state transformations [3][4][5][6][7]11].…”

“…Studies of heterogeneous nanosystems are of technological importance and can be useful in gaining insight into the mechanism of solid state transformations [3][4][5][6][7]11]. Indium, molybde num(VI) oxide, and related materials are widely used in scientific, technological, and industrial applications owing to their advantageous properties and, as a conse quence, have attracted considerable attention of researchers in various fields [1][2][3][4][8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

“…Evaporants were contained in 3 mm thick molybdenum boats. As substrates, we used photo graphic plates, which were pretreated in a potassium dichromate solution and concentrated sulfuric acid, rinsed with distilled water, and dried [7,11,21]. The substrates thus prepared were optically transparent in the range 300-1100 nm.…”
