The transport mechanism of YSZ thin films prepared by MOCVD

Thin films for micro solid oxide fuel cells

“…In studies of (ZrO 2 ) 0.95 (Y 2 O 3 ) 0.05 deposited by CVD onto different substrates with a constant film thickness and a constant average grain size [177,178], a severe impact of the substrate material on the electrical properties was found. The authors proposed that the mismatch of thermal expansion coefficients (TEC) between the substrate and the YSZ resulted in differently compressed thin films states, affecting the electrical conductivity.…”

The grain and grain boundary impedance of sol–gel prepared thin layers of yttria stabilized zirconia (YSZ)

“…During the last years, thin film ion conductors have stirred a lot of interest [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] . This is partly due to their use as model systems to study material properties only observable in nanometer scaled systems, for which the term “nano-ionics” has been coined.…”

Flame retardant and hydrophobic cotton fabrics from intumescent coatings

“…Developing approaches to improve the fire resistance of these abundant flammable materials is becoming an increasingly significant research focus [2][3][4][5][6][7][8][9]. Many techniques have been investigated as a means to impart flame retardancy to different substrates, including ultraviolet curing of functional monomers and pre-polymers [10], plasma technology to activate substrate surface [11], physical and chemical vapor deposition to generate a protective thin film on substrates [12][13][14], sol-gel process to form a coating layer directly on substrates [15,16], and layer-by-layer (LbL) assembly of a thin coating on substrate surface [17][18][19][20][21][22]. All of these technologies aim to modify the substrate surface in a certain way that will impede combustion initiation and propagation.…”
