Physical vapor deposition (PVD), sometimes (especially in singlecrystal growth contexts) called physical vapor transport (PVT), describes a variety of vacuum deposition methods which can be used to produce thin films and coatings. PVD is characterized by a process in which the material goes from a condensed phase to a vapor phase and then back to a thin film condensed phase.

Milling is a unit operation where mechanical energy is applied to physically break down coarse particles to finer ones and hence, is regarded as a "top–down" approach in the production of fine particles . As virtually every drug can be comminuted to fine particles regardless of its solubility in aqueous or nonaqueous solvents, the "top–down" approach has wider commercial and

For the first six days, put down 3 cups of organic fertilizer per bale every other day, and water the bales to push the fertilizer down and thoroughly saturate the straw. On the off days, simply water the bales. (Tip: try to ignore the neighbors staring suspiciously from their windows.) Days 7 through 9, lay down cups of organic fertilizer each day and water. Day 10 put down 3 cups with

Face milling is the most common milling operation and can be performed using a wide range of different tools. Cutters with a 45º entering angle are most frequently used, but round insert cutters, square shoulder cutters and side and face mills are also used for certain conditions. Be sure to choose the right cutter for the operation for optimal productivity (see information on choice of tools

Posterior vitreous detachment (PVD) is a condition where your vitreous comes away from the retina at the back of your eye. This is caused by changes in your vitreous gel. PVD isn''t painful and it doesn''t cause sight loss, but you may have symptoms such as seeing floaters (small dark spots or shapes) and flashing lights. These symptoms will calm down as your brain learns to ignore them

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
