Introduction: The image quality as well as film speed is influenced by the film processing conditions. Different combinations of films and processing methods affect the diagnostic accu-racy. Temperature and developer exhaustion result in different image quality. The purpose of this study was to evaluate the influence of film type and processing conditions on caries detec-tion.  Material a...

A transparent and flexible film heater was fabricated; based on a hybrid structure of poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) and silver nanowires (Ag NWs) using a screen printing; which is a scalable production technology. The resulting film integrates the advantages of the two conductive materials; easy film-forming and strong adhesion to the substrate of the polym...

In the film formation of latex, particle deformation can occur by processes of wet sintering, dry sintering, or capillary action. When latex films dry nonuniformly and when particles deform and coalesce while the film is still wet, a detrimental skin layer will develop at the film surface. In their process model, Routh and Russel proposed that the operative particle deformation mechanism can be...

Thin films of tin sulfide/cadmium sulfide (SnS/CdS) were prepared bythermal evaporation method at room temperature on a glass substrate and then annealedat different temperature with the aim of optimizing the optical properties of the materialfor use in photovoltaic solar cell devices. The effect of annealing on optical propertiesof SnS/CdS film was studied in the temper...

In order to develop film electrodes for the surface acoustic wave (SAW) devices operating in harsh high-temperature environments, novel Al₂O₃/Pt/ZnO/Al₂O₃ multilayered film electrodes were prepared by laser molecular beam epitaxy (LMBE) at 150 °C. The first Al₂O₃ layer was used as a barrier layer to prevent the diffusion of Ga, La, and Si atoms from the La₃Ga₅SiO14 (LGS) substrate to the film e...

The effect of both surface coupling Js and surface magnetic field Hs on the dependency of the layering temperature TL as a function of the thickness N , of a spin−1/2 Ising film is studied using mean field theory. It is found that for Js greater than a critical value (Jsc = 1.30), the layering temperature decreases when the film thickness N increases for any values of Hs. While, for Js < Jsc, t...

A submicrometer-thick zirconium dioxide film was deposited on the tip of a polished C-plane sapphire fiber to fabricate a temperature sensor that can work to an extended temperature range. Zirconium dioxide was selected as the thin film material to fabricate the temperature sensor because it has relatively close thermal expansion to that of sapphire, but more importantly it does not react appre...

In order to develop a film electrode for the surface acoustic wave (SAW) devices working in high temperature, harsh environments, novel AlN/Pt/ZnO multilayers were prepared using pulsed laser deposition (PLD) systems on langasite (LGS) substrates. The AlN film was used as a protective layer and the ZnO buffer layer was introduced to improve the crystal quality of Pt films. The results show that...

Polarized Raman spectra of NiFe2O4 (NFO) films of varying thickness and growth temperature are investigated and discussed. We find that the relaxed films obtained at higher temperatures on MgAl2O4 (MAO) substrate exhibit spectra identical to those of single crystals and provide strong indications for ordering of Ni2+ and Fe3+ at the octahedral sites. There is evidence for a certain degree of B-...
