Cationic initiators are most commonly compounds or combinations of compounds that can transfer a hydrogen ion, H+, to the monomers, thereby converting the monomer into a cation.
Brønsted Lowry theory, also called proton theory of acids and bases, a theory, introduced independently in 1923 by the Danish chemist Johannes Nicolaus Brønsted and the English chemist Thomas Martin Lowry, stating that any compound that can transfer a proton to any other compound is an acid, and the compound that accepts the proton is a base.
For much of organic chemistry, an acid may be defined as a compound that can transfer a proton (H+) to a base, and a base may be defined as any entity with an unshared pair of electrons (and therefore capable of accepting a proton).
In one study, researchers fed pregnant rats a diet that was deficient in methyl donors (substances such as folic acid that can transfer methyl compounds to other substances), then assessed the offspring for changes in hippocampal DNA methylation and gene expression as well as associated behavioral changes in female pups as they aged.
Another issue that came to light was what Tice calls "compound carryover"—some compounds can be transferred from one set of plates to another by the pin tools used in the quantitative high-throughput screening system.
Furthermore, these compounds can be transferred across the blood brain barrier and accumulate in the brain (Brouwer and van den Berg 1986; Cheek et al. 1999; Darnerud et al. 1996; McKinney 1989).
Collars make contact with the skin of your pet and thus chemicals or active compounds can be transferred to the skin or fur of your pooch which leads to removal of ticks.
If she hates it, she can transfer.
They can transfer a liquid in volumes less than a zeptoliter [8], as well as can transfer small amounts of materials such as nanoparticles, chemical compounds, and proteins.
