  • (20) The artist covered every inch of the steps in front of his house in tiles, ceramics and mirrors – originally in the green, yellow, blue and white of the Brazilian flag, later adding tiles in other colours brought by visitors.

Polymer


Definition:

  • (n.) Any one of two or more substances related to each other by polymerism; specifically, a substance produced from another substance by chemical polymerization.

Example Sentences:

  • (1) Five days later, the animals were randomly assigned to one of four treatment groups: Group 1 received intracranial implantation of controlled-release polymers containing dexamethasone; Group 2 received intraperitoneal implantation of controlled-release polymers containing dexamethasone; Group 3 received serial intraperitoneal injections of dexamethasone; and Group 4 received sham treatment.
  • (2) In spite of important differences in size, chemical composition, polymer density, and configuration, biological macromolecules indeed manifest some of the essential physical-chemical properties of gels.
  • (3) The acetonitrile extract is concentrated and analyzed by HPLC, using a new polymer-based column, and detected by UV spectroscopy at 270 nm.

  • (8) By performing countercurrent distribution in the presence of a polymer-ligand, the protein that binds the polymer-ligand can be separated from a heterogenous mixture.
  • (9) Pulse labeling of the polymer with [2-3H]adenosine was also maximal at the same time points.
  • (10) Charged polymers, known to alter cell surface characteristics, reversibly inhibit the intercellular communication required in kidney tubule induction.
