DPRA is designed to mimic the covalent bonding of electrophilic chemicals (sensitizers) to nucleophilic domains present in skin proteins.
The first includes aspirin inactivating the COX-1 or COX-2 enzyme through formation of covalent bonds, thus suppressing inflammation, and the second includes reactions through reversible covalent bonding that catalyze bodily enzymatic reactions.
However, introduced as a central concept early in the course, electronegativity can be used to explain vital chemical concepts such as ionic and covalent bonding, polarity, and hydrogen bonding.
Smith, Stevens, and Wood of Siemens Energy have developed an electrical insulation with high thermal conductivity using thermal-conducting nanoparticles bonded to a resin matrix by covalent bonding.
However, because the two non-bonding pairs are closer to the oxygen atom, they repel the two covalent bonding pairs, effectively pushing the two hydrogen atoms closer together.
Although these IR spectra themselves do not provide direct evidence for any covalent bonding between the PNIPA hydrogel and modified silica, the results indicating the presence of ester carbonyl groups in the absence of any double bonds in the PNIPA/modified silica hydrogel suggested that the double bonds introduced on the modified silica were copolymerized with NIPA and that the modified silica was bound with PNIPA hydrogel via covalent bonding.
