Desertification of the Peritoneum by Thin-Film Evaporation During Laparoscopy
OBJECTIVE To assess the effects of gas flow during insufflation on peritoneal fluid and peritoneal tissue regarding transient thermal behavior and thin-film evaporation. The effects of laparoscopic gas on peritoneal cell desiccation and peritoneal fluid thin-film evaporation were analyzed. METHODS Measurment of tissue and peritoneal fluid and analysis of gas flow dynamics during laparoscopy. ...
متن کاملAl-Doped ZnO Thin Film Transistors by Thermal Evaporation
In this paper, Al-doped ZnO thin film transistors (AZO-TFT) were fabricated by the thermal evaporation growth of AZO channel layer on a silicon substrate at temperatures below 250°C. A SiO2 dielectric layer grown by the horizontal furnace was used as a gate. An active layer thickness of 10nm was measured by Atomic Force Microscopy (AFM), and its surface had root mean square (rms) roughness 12.6...
متن کاملStudies on Optical Properties of ZnS Thin Film by Thermal Evaporation Technique
The most significant process for optical coating is variant of vacuum deposition. Zinc sulphide having direct and large band gap which is use in opto electronics. By using ZnS material in thermal evaporation technique and characterizing the minimum reflectance and maximum transmittance in visible wavelength and energy gap increases with increasing thickness having direct and large band gap. Whe...
متن کاملThin Film Evolution over a Thin Porous Layer: Modeling a Tear Film on a Contact Lens
We examine a mathematical model describing the behavior of the precontact lens tear film of a human eye. Our work examines the effect of contact lens thickness and lens permeability on the film dynamics. Also investigated are gravitational effects and the effects of different slip models at the fluid-lens interface. A mathematical model for the evolution of the tear film is derived using a lubr...
متن کاملA microscale model for thin-film evaporation in capillary wick structures
A numerical model is developed for the evaporating liquid meniscus in wick microstructures under saturated vapor conditions. Four different wick geometries representing common wicks used in heat pipes, viz., wire mesh, rectangular grooves, sintered wicks and vertical microwires, are modeled and compared for evaporative performance. The solid-liquid combination considered is copper-water. Steady...
