What's the difference between coacervation and separation?

Coacervation


Definition:

  • (n.) A heaping together.

Example Sentences:

  • (1) Polydispersity of PS played a vital role in determining variables at the critical state of phase separation, such as the composition of coacervate (dense) and lean phases.

  • (6) The structure of the polypentapeptide is one of limited order below 20 degrees C which undergoes an inverse temperature transition to a conformation characterized by a regularly recurring beta-turn at 40 degrees C. The temperature profile for the conformational change is compared to the temperature dependence of elastomeric force of gamma-irradiation cross-linked polypentapeptide coacervate.
  • (7) Coacervates have been suggested as models for cytoplasm since cytoplasm is also essentially an aqueous phase of water-protein-colloid complexes.

  • (13) H-(Ala-Pro-Gly-Gly)n-Val-OMe did not coacervate even at as high a temperature as 100 degrees, and H-(Ala-Pro-Gly-Val-Gly)n-Val-OMe did not coacervate; however, it precipitated irreversibly around 65--70 degrees C. This suggests the critical role of the Val-Pro hydrophobic side chain interaction in coacervation.
  • (14) Electrophoresis and gelatin adsorption studies revealed that encapsulation by way of simple coacervation by gelatin is caused by the affinity between core and coacervate resulting from gelatin adsorption on the core surface.
  • (15) Recovery of the product as water-insoluble discrete units required the use of formaldehyde and isopropanol for coacervate denaturation and flocculation, respectively.
  • (16) Spherical droplets of clofibrate, prepared by a capillary jet method, were encapsulated in gelatin by simpel coacervation, using sodium sulfate as the coacervating agent.
  • (17) Terbutaline sulphate microcapsules were prepared by coacervation-phase separation induced by solvent evaporation technique.
  • (18) Yields and equilibrium water contents of complex coacervates from these polymers were measured, and microcapsule forming systems based on this effect were developed as potential prostheses for organ transplantation.
  • (19) The stability ranges of the coacervates under varying conditions of temperature, pH, salt concentration and concentration of added organic solvent have been investigated with results that suggest a marked sensitivity of elastin conformation to solution conditions.
  • (20) In complex coacervation method optimal ratio was 0.5:1.

Separation


Definition:

  • (n.) The act of separating, or the state of being separated, or separate.
  • (n.) Chemical analysis.
  • (n.) Divorce.
  • (n.) The operation of removing water from steam.

Example Sentences:

  • (1) It was tested for recovery and separation from other selenium moieties present in urine using both in vivo-labeled rat urine and human urine spiked with unlabeled TMSe.
  • (2) Chapter one Announcement of the Islamic Caliphate The announcement of the renewal of the caliphate in Iraq in the year 1427AH [2006] was the arbiter between division and separation as well as the glory of the Muslims.

  • (5) And this is the supply of 30% of the state’s fresh water.” To conduct the survey, the state’s water agency dispatches researchers to measure the level of snow manually at 250 separate sites in the Sierra Nevada, Rizzardo said.
  • (6) Completeness of isolation of the coronary and systemic circulations was shown by the marked difference in appearance times between the reflex hypotensive responses from catecholamine injections into the isolated coronary circulation and the direct hypertensive response from a similar injection when the circulations were connected as well as by the marked difference between the pressure pulses recorded simultaneously on both sides of the aortic balloon separating the two circulations.4.
  • (7) In the present study, respirometric quotients, the ratio of oral air volume expended to total volume expended, were obtained using separate but simultaneous productions of oral and nasal airflow.
  • (8) The sensitivity of an indirect fluorescent antibody (IFA) test (screening test) for the detection of antibodies to cytomegalovirus (CMV) was examined by using 128 serum specimens and quaternary aminoethyl (QAE)-Sephadex A50 column chromatography to separate IgM from IgG class antibodies.
  • (9) This experimental system allows separation of three B lymphocyte developmental stages: early differentiation in vitro, progression to IgM secretion in vivo, and late differentiation dependent upon mature T lymphocytes in vivo.
