2. Ion-exchange resin - Wikipedia

   en.wikipedia.org/wiki/Ion-exchange_resin

   Ion-exchange resin beads. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.

3. Seed bead - Wikipedia

   en.wikipedia.org/wiki/Seed_bead

   Not every 20 inch strand of size 11/0 beads weighs the same. However, there are some online calculators, which can be used for conversion from hanks to grams and from grams to hanks. A hank of size 2/0 bugles or size 11/0 seed beads generally weighs between 30 and 40 grams, depending on manufacturing variations, coatings or linings.

4. Speeds and feeds - Wikipedia

   en.wikipedia.org/wiki/Speeds_and_feeds

   Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

5. Strain rate - Wikipedia

   en.wikipedia.org/wiki/Strain_rate

   The definition of strain rate was first introduced in 1867 by American metallurgist Jade LeCocq, who defined it as "the rate at which strain occurs. It is the time rate of change of strain." In physics the strain rate is generally defined as the derivative of the strain with respect to time. Its precise definition depends on how strain is measured.

6. Shear rate - Wikipedia

   en.wikipedia.org/wiki/Shear_rate

   The shear rate for a fluid flowing between two parallel plates, one moving at a constant speed and the other one stationary (Couette flow), is defined by ˙ =, where: ˙ is the shear rate, measured in reciprocal seconds;

8. Calculation of glass properties - Wikipedia

   en.wikipedia.org/wiki/Calculation_of_glass...

   The calculation of glass properties allows "fine-tuning" of desired material characteristics, e.g., the refractive index. [1]The calculation of glass properties (glass modeling) is used to predict glass properties of interest or glass behavior under certain conditions (e.g., during production) without experimental investigation, based on past data and experience, with the intention to save ...

9. Conversion (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Conversion_(chemistry)

   Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
