Translationstemperare [il metallo]temperaranneal
anneal[ə′nēl] (engineering) To treat a metal, alloy, or glass with heat and then cool to remove internal stresses and to make the material less brittle. Also known as temper. (genetics) To recombine strands of complementary deoxyribonucleic acid that were separated by heating or other means of denaturation. annealTo take the brittleness out of metal, plastic or certain carbon composites. Performed in the preparation of new products or in their restoration, annealing is accomplished via a heat treating process.anneal
anneal [ah-nēl´] 1. to heat a material, such as glass or metal, followed by controlled cooling to remove internal stresses and induce a desired degree of toughness, temper, or softness of the material.2. to homogenize an amalgam alloy ingot by heating it in an oven.3. to heat a material, such as gold foil, to volatilize and drive off impurities from its surface, and to increase its cohesive properties.an·neal (an-nēl'), 1. To soften or temper a metal by controlled heating and cooling; the process makes a metal more easily adapted, bent, or swaged, and often less brittle. 2. In dentistry, to heat gold leaf preparatory to its insertion into a cavity, to remove adsorbed gases and other contaminants. 3. The pairing of complementary single strands of DNA; or of DNA-RNA. 4. The attachment of the ends of two macromolecules, for example, two microtubules annealing to form one longer microtubule. 5. In molecular biology, annealing is a process in which short sections of single-stranded DNA from one source are bound to a filter and incubated with single-stranded, radioactively conjugated DNA from a second source. Where the two sets of DNA possess complementary sequences of nucleotides, bonding occurs. The degree of relatedness (homology) of the two sets of DNA is then estimated according to the radioactivity level of the filter. This technique plays a central role in the classification of bacteria and viruses. Synonym(s): nucleic acid hybridization6. To renature proteins or polynucleic acids by slow cooling. [A.S. anaelan, to burn] an·neal (ă-nēl') Process by which oligonucleotides affix to targeted DNA sequences. [A.S. anaelan, to burn]an·neal (ă-nēl') In dentistry, to heat gold leaf preparatory to its insertion into a cavity to remove adsorbed gases and other contaminants. [A.S. anaelan, to burn]anneal
