Sentence examples for migrate and aggregate from inspiring English sources
However, the metal nanoparticles migrate and aggregate easily on the supports, thus their chemical activity decreases rapidly.
H2O molecules are preferentially adsorbed on the sulfur- and oxygen-containing groups at low moisture, and then migrate and aggregate into clusters in the middle of enterable pores at high moisture.
When the reducing agent H2 diffuses into the cavity, the formed CuO nuclei are further reduced to metallic Cu nuclei, which tend to migrate and aggregate to form bigger particles.
The newly formed silver nanoparticles could migrate and aggregate onto both sides of substrate films, forming continuous and compact silver layers that result in excellent conductivity, i.e. ∼0.6 and 0.5 Ω/sq on the upside and downside surfaces, respectively.
These reactions were usually carried out in liquid phase at harsh conditions with high temperature and pressure, however, catalysts deactivation frequently occurred since small metal NPs were inclined to migrate and aggregate as well as dissolve and leach in such acid systems.
They delaminate, migrate and aggregate to form the islets of Langerhans [10], [11].
Measurements of DR UV vis spectra and TEM images revealed that a part of the Ag NPs migrated and aggregated on the photocatalyst surface to become larger particles during the photocatalytic reaction, which would be related to the decrease of the photocatalytic activity.
For example, when starved of amino acids, Myxobacteria detect surrounding cells in a process known as quorum sensing, migrate toward each other, and aggregate to form fruiting bodies up to 500 micrometres long and containing approximately 100,000 bacterial cells.
Vacancy-di-interstitial pairs have been also produced, though by electron irradiation and through a different mechanism: Individual interstitials migrate during the irradiation and aggregate to form di-interstitials; this process occurs preferentially near the lattice vacancies.
The dissociated cells then settle, migrate, and form active aggregates in which the archaeocytes play an important role.
During gastrulation, the mesodermal cells migrate out of the primitive steak and aggregate and assemble into blood islands.
