Cooking fresh sweet corn in boiling water is simple: Shuck the corn. Bring water to a boil in a large pot and boil the corn for five to 10 minutes, depending on how soft you like your corn. You can cook fresh sweet corn in the microwave in just minutes. Shuck the ears and wrap them in plastic cling wrap. Microwave them for 90 seconds per ear.
PDC drill bits. Polycrystalline diamond materials, for use in polycrystalline diamond compact (PDC) bits, are one of the most important material advances for oil drilling tools in recent years. Fixed-head bits rotate as one piece and contain no separately moving parts. When fixed-head bits use PDC cutters, they are commonly called PDC bits.
Stearic acid. Water soluble wax, Carbowax, polyethylene glycol and PEG are all terms used to describe the same material. Chemically they are polyethylene glycols of varying degrees of polymerisation and molecular weights, or polyethylene glycol fatty acid esters, such as polyethylene glycol monostearate.ike paraffin waxes, polyethylene glycol is usually a mixture of materials with varying molecular weights, due in this case to varying degrees of polymerisation, rather than a single molecular entity. When purchasing, the molecular weight has to be specified to ensure the correct material.
