Thin-film interference is a natural phenomenon in which light waves reflected by the upper and lower boundaries of a thin film interfere with one another, increasing reflection at some wavelengths and decreasing it at others. When white light is incident on a thin film, this effect produces colorful reflections.
Thin-film drug delivery uses a dissolving film or oral drug strip to administer drugs via absorption in the mouth (buccally or sublingually) and/or via the small intestines (enterically). A film is prepared using hydrophilic polymers that rapidly dissolves on the tongue or buccal cavity, delivering the drug to the systemic circulation via ...
4 PH 3 + 5 O 2 → 2 P 2 O 5 + 6 H 2. Glasses containing both boron and phosphorus (borophosphosilicate glass, BPSG) undergo viscous flow at lower temperatures; around 850 °C is achievable with glasses containing around 5 weight % of both constituents, but stability in air can be difficult to achieve. Phosphorus oxide in high concentrations ...
Thin-film optics is the branch of optics that deals with very thin structured layers of different materials. [1] In order to exhibit thin-film optics, the thickness of the layers of material must be similar to the coherence length ; for visible light it is most often observed between 200 and 1000 nm of thickness.
The very thin and tough film allowed 6,000-foot (1,800 m) reels to be exposed on long-range U-2 reconnaissance flights. [ 10 ] In 1964, NASA launched Echo II , a 40-metre (131 ft) diameter balloon constructed from a 9-micrometre (0.00035 in) thick mylar film sandwiched between two layers of 4.5-micrometre (0.00018 in) thick aluminium foil ...

However, CNT thin films show many advantages over other transparent electrodes in the IR range. CNT thin films were reported to have a transmittance of over 90% in this range (400 nm – 22 μm). This paves the way for new applications, indicating that CNT thin films can be used as heat dissipaters in solar cells because of this high transmittance.
Flat panel display manufactures have found use for MIM TFDs as switches in active matrix technology such as active matrix liquid crystal displays (AMLCD). Historically in AMLCDs the switching device of choice for pixels has been the thin-film transistor (TFT), however MIM TFD based displays have had some commercial success as they are simpler to make; only requiring two to three photo ...
