Dissolution[edit] In the most common situation‚ a tablet is ingested and passes through the esophagus to the stomach. The rate of dissolution is a key target for controlling the duration of a drug’s effect‚ and as such‚ several dosage forms that contain the same active ingredient may be available‚ differing only in the rate of dissolution. If a drug is supplied in a form that is not readily dissolved‚ the drug may be released more gradually over time with a longer duration of action. Having a

forms a film that runs off taking any loose dirt deposits with it. 4. Anti-fogging: clear view is now possible without the use of electricity‚ due to using ultra-thin coating of nanoscaler titanium dioxide‚ which exhibits a high surface energy. 5. Solar protection: Electrochromatic glass with an ultra-thin Nano coating needs only to be switched once to change state‚ gradually changing to a darkened yet transparent state. At present the maximum dimension of glazing panels is limited.

Daguerre who‚ in 1837‚ developed a process for printing images on a silver coated copper plate. This type of printed image is called a daguerreotype‚ and is made by polishing and cleaning a silver-coated copper plate and then reacting the silver coating with iodine vapors to form light-sensitive silver iodide. The silver iodide coated plate is then exposed to light through the optics of a camera that projects and focuses an image on the plate. In the ensuing reaction‚ the silver ions are reduced
