What's the difference between recrystallization and rock?

Recrystallization


Definition:

  • (n.) The process or recrystallizing.

Example Sentences:

  • (5) The blood-brain barrier in the rhesus monkey was opened to intravascular Evans blue-albumin, without causing brain edema or altering brain electrolytes, by perfusing 2.5 molal recrystallized D,L-lactamide into the internal carotid artery for 20--30 sec.
  • (6) Electrophoresis, microscopical observation and pH dependency of encapsulability of recrystallized cores revealed that the electrostatic attractive force between gelatin molecules in solution and a polymer attached to the core particle cause gelatin adsorption on the core surface to result in a great improvement in encapsulability.
  • (7) The porosity in lased enamel was overall very similar to that seen in enamel heated in an electric furnace to a temperature of 600 degrees C. The presence of recrystallized enamel crystals indicated a temperature rise of approximately 1000 degrees C and the grain growth indicated that a temperature > or = 1000 degrees C existed for some time after the laser irradiation.
  • (8) Products of cholesterol auto-oxidation were concentrated from several lots of USP-grade cholesterol by recrystallizing cholesterol from the methanol extract, retaining the mother liquor, and evaporating the residuum to dryness under vacuum.
  • (9) Recrystallization of the synthetic product produced material identical in all respects with natural PGE1.
  • (10) Experiments showed that sulphadimidine crystals recrystallized from ethanol had better dissolution and absorption characteristics than sulphadimidine crystals recrystallized from methanol.
  • (11) Thermal studies (DSC and HSM) showed that form II melts at 196 degrees C, while form I melts at 193 degrees C, immediately followed by a resolidification and remelt at 196 degrees C. The conversion of form II to form I was accomplished by recrystallization from ethanol or methanol, and the form I-to-form II transition was obtained by controlled heating of form I around 194 degrees C. Quantitative XRD was used to determine the polymorphic composition, with a detection limit of less than 1% of the minor form and a linearity of 0-10% form I in form II (correlation coefficient of 0.999).
  • (12) Microcapsule batch reproducibility depended mainly on the variation in particle size distribution of the recrystallized core material.
  • (13) After the administration of 3-H-testosterone to castrated hamsters, extracts from crude nuclei were separated into bound and free fractions by gel filtration of Sephadex G-25, Subsequent analysis by thin-layer chromatography and recrystallization showed that dihydrotestosterone was the predominant radioactive steroid in the bound fraction and that it increased steadily with time until 1 hr after the injection.
  • (14) 1,2-Dimethyl-3-hydroxy-4-pyridone (1), a crystalline oral iron chelator, forms an acetic acid solvate (2) on recrystallization from acetic acid and carbon tetrachloride.
  • (15) Recrystallization of the purified enzyme under different conditions readily produces a variety of single crystals.
  • (16) Ice recrystallization was practically absent at the temperature normally used in cryo-sectioning (-70 degrees C).
  • (17) A convenient, detailed procedure is given for the recrystallization of commercial dithionite from 0.1 M NaOH-methanol under anaerobic conditions.
  • (18) Thus, the protein penetrates partway into the bilayer, distorts the packing of the lipid fatty acid chains, and prevents recrystallization, thus decreasing the phase transition temperature.
  • (19) Winter stem fluid from the bittersweet nightshade, Solanum dulcamara L., also showed the recrystallization inhibition activity characteristic of the animal thermal hysteresis proteins (THPs), suggesting a possible function for the THPs in this freeze tolerant species.
  • (20) The chimeric proteins varied in their effectiveness of inhibiting ice recrystallization according to the number of 11-amino acid repeats present in the antifreeze moiety.

  • (n.) Fig.: Anything which causes a disaster or wreck resembling the wreck of a vessel upon a rock.

  • (v. t.) To cause to sway backward and forward, as a body resting on a support beneath; as, to rock a cradle or chair; to cause to vibrate; to cause to reel or totter.
  • (v. t.) To move as in a cradle; hence, to put to sleep by rocking; to still; to quiet.
  • (v. i.) To move or be moved backward and forward; to be violently agitated; to reel; to totter.
