Current methodologies used for the inference of thin film stress through curvature measurements are strictly restricted to stress and curvature states which are assumed to remain uniform over the entire film/substrate system. Recently Huang, Rosakis and co-workers [Huang, Y., Ngo, D., Rosakis, A.J., 2005. Non-uniform, axisymmetric misfit strain: in thin films bonded on plate substrates/substrat...

PURPOSE The purpose of this work was to gather preliminary data in normals and dry eye subjects, using a new, non-invasive imaging platform to measure the thickness of pre-corneal tear film. METHODS Human subjects were screened for dry eye and classified as dry or normal. Tear film thickness over the inferior paracentral cornea was measured using laser illumination and a complementary metal-o...

Objective- This study aimed at evaluation of histopathological findings of application of chitosan- nano selenium biodegradable film on full thickness excisional wound healing in rats. Design- Experimental Study Animals- Seventy-two male Wistar rats Procedures- Animals were randomized into six groups of 12 animals each. Group I: Animals with created wounds and no...

This paper reports the effect of the different deposition methods towards the ZnO nanostructure crystal quality and film thickness on the polyimide substrate. The ZnO film has been deposited by using the spray pyrolysis technique, sol-gel and RF Sputtering. Different methods give a different nanostructure of the ZnO thin film. Sol gel methods, results of nanoflowers ZnO thin film with the thick...

The transmission probability of the free electron scattered by the quantum well in metal film may reveal the phenomenon of resonance. This transmission resonance, appearing above the vacuum level, can be probed by scanning tunnelling spectroscopy (STS). In this paper, STS is used to observe the transmission resonance on Ag films grown on Si(111)7 × 7 surfaces. The transmission resonance appears...

Fully-depleted SOI devices are being considered for low power applications due to their threshold voltage, sub-threshold slope and capacitance advantages over other technologies. However, the threshold voltage of a fully-depleted SOI device is a strong function of the silicon film and sacrificial oxide thicknesses. Thus, to fully realize the advantages of fully-depleted SOI devices in commercia...

A suction line of a refrigeration cycle with vertical upward flow is one area where the refrigeration oil tends to accumulate. This paper discusses the flow characteristics of the oil film in a pipe with the vertical upward flow. Air and oil two-phase flow is used as the first step of the study and the flow pattern of the oil film in the vertical upward flow is observed. The oil film thickness ...

An implementation of plasmon resonances in nanocomposite thin films for biosensors is discussed. The effect is studied in the system of modified Au inclusions inside the Teflon matrix. The optical response of the nanocomposite thin film with inhomogeneous distribution of embedded coated Au spherical nanoparticles across the film thickness is analyzed. The absorption profiles are calculated in a...

Tear film stability and its interaction with the corneal surface play an important role in maintaining ocular surface integrity and quality of vision. We present a non-invasive technique to quantify the pre-corneal tear film thickness. A cMOS camera is used to record the interference pattern produced by the reflections from multiple layers of the tear film Principles of spatial autocorrelation ...
