Mattinson's idea was to first heat or anneal the zircons, sealing off the least damaged areas of the crystal, then using a strong reagent, hydrofluoric acid, to eat away the heavily damaged areas.
The heat of welding will anneal the copper in the heat-affected area adjacent to the weld and reduce the strength provided by cold working.
For the high-silicon nodular irons, high-temperature heat treatment is advised in all cases to anneal any pearlite and stabilize the casting against growth in service.
The ‘EZ Beader’ from PARAGON is a new bead kiln designed to anneal glass beads to prevent breakage during cooling.
Equal amounts of each RNA were mixed, denatured, and annealed by slow cooling.
Two single-stranded oligos, GAGAEXHO and GAGAESAL, were annealed to generate a double-stranded oligo with XhoI and SalI cohesive ends.
All annealers and fusers are sold two ways; with and without an infinite control switch.
Sense and antisense RNAs were annealed to create double-stranded RNA by heating to 93°C for 30 s, followed by twenty-five 30-s incubations at 2° decrements for each incubation.
A stock solution of double stranded DNA was prepared by annealing the two single strands in 100 mM. pH 7.2 sodium phosphate buffer at a DNA concentration of 14 M (in helices).
In heat treatable alloys, annealing also may be accompanied by precipitation and changes in solute concentration.
