Introduction: The increasing sophistication of the industries requiring optical thin films from unconventional materials calls for alternative fabrication methods. Thin film for use in broadband and narrowband filtering applications, including dense wavelength division multiplexing (DWDM), optical amplification, switching, modulation of light signals, grating based devices, infrared light trans...

Long-term, localized delivery of small molecules from a biodegradable thin film is challenging owing to their low molecular weight and poor charge density. Accomplishing highly extended controlled release can facilitate high therapeutic levels in specific regions of the body while significantly reducing the toxicity to vital organs typically caused by systemic administration and decreasing the ...

We studied the OH oxidation of submicron aerosol particles consisting of pure palmitic acid (PA) or thin (near monolayer) coatings of PA on aqueous and effloresced inorganic salt particles. Experiments were performed as a function of particle size and OH exposure using a continuous-flow photochemical reaction chamber coupled to a chemical 5 ionization mass spectrometer (CIMS) system, for detect...

Abstract Thin copper films with thickness ∼28 nm deposited on SiO 2 substrate the vacuum electron beam evaporation method and treated by UV-ozone are studied. It was found that a treatment of film causes rapid formation thin ∼3-4 oxide film. XPS analysis showed CuO predominates in this The formed effectively protects against following oxidation. presented is simpler cheaper approach compared to...

Abstract: Different thickness of Cu2S thin films were prepared by vacuum evaporation under a pressure of 10-6 torr at an evaporation rate of 3Å /sec. Cu2S has direct band gap energy and indirect band gap energy at 1.2eV and 1.8 eV respectively. This paper presents the analysis of structural and optical properties of the Cu2S thin film by X-ray diffractometer (XRD) and UV-Vis-NIR Spectrophotomet...

titanium nitride-copper (tin-cu) nanocomposite films were deposited onto stainless steel substrate using hollow cathode discharge ion plating technique. the influence of cu content in the range of 2-7 at.% on the microstructure, morphology and mechanical properties of deposited films were investigated. structural properties of the films were studied by x-ray diffraction pattern. topography of t...

Thin liquid films are central to everyday life. They are ubiquitous in modern technology (pharmaceuticals, coatings), consumer products (foams, emulsions) and also serve vital biological functions (tear film of the eye, pulmonary surfactants in the lung). A common feature in all these examples is the presence of surface-active molecules at the air-liquid interface. Though they form only molecul...

Resonant absorbers based on nanostructured materials are promising for variety of applications including optical filters, thermophotovoltaics, thermal emitters, and hot-electron collection. One of the significant challenges for such micro/nanoscale featured medium or surface, however, is costly lithographic processes for structural patterning which restricted from industrial production of compl...

Plasma-induced etching of dielectric thin films is widely used in ~ntegratedcircuit preparation technology. It normally involves the interaction of gas discharge species with a thin-film surface in order to produce volat~le reaction products. The ultimate goal is to etch through a frlm in a spatially selective manner and to thereby generate a desired pattern. This process also occurs unintentio...
