This induces a slight electronegative charge on the electronegative atom with a slight positive charge around the carbon atom.
The higher AC conductivity of PANI/CuS composites than that of PANI may be due to the strong interaction between the metal particles and electronegative nitrogen of PANI.
The trifluoromethyl group is much more electronegative than the methyl group.
To the best of our knowledge, this would be the first time this porphyrin has been made and it may as well be the most electronegative porphyrin so far made.
Projects currently funded are in the area of thin oxides, electronegative plasmas, microbiocontamination in ultrapure water, BEOL yield modeling, CMP and post-CMP cleaning.
The trivalent nitrogen in copolymer 17 is thus more electronegative hence less basic or nucleophilic than its counterpart in homopolymer 12, thereby imparting greater stability to the copolymer as it is unable to push the electrons required for decomposition to 26 as depicted in Scheme 6.
1981); the more electronegative ALAD2 enzyme may thus have a higher affinity/stability for the lead cation than ALAD1 (Wetmur et al.
x] pollutant formation, soot formation, electron scavenging by electronegative additives to form negative ions, and the ion chemistry of metals at high temperatures.
The less electronegative B atoms resulted in the lower binding energy of N.
The ALAD 2 allele has been shown to modify the toxicokinetics of lead by coding for a more electronegative enzyme that may bind positively charged lead ions more tightly than does the ALAD-1 protein (Wetmur 1994; Wetmur et al.
Lemieux also continued studies of the anomeric effect, a term which he introduced in 1958 to describe the effect responsible for an electronegative substituent such as chlorine or acetoxyl at an anomeric centre preferring an axial to an equatorial orientation.
As for the growing process from P(AN-co-VA) microspheres to waxberry-like P(AN-co-VA)/Ag composites, it is suggested that the electronegative groups (--CN) on the P(AN-co-VA) spheres surface act as anchored sites for the growth of Ag nanoparticles by attracting or chelating positive [Ag.
2] is probably attracted to the highly electronegative fluorine atoms in the polymer side groups.
Since the carboxylate group is electronegative in water, higher carboxylate concentrations will lead to repulsion among these groups and a decrease of water absorbency, although carboxylate group have better water absorbency than carboxylic group does.
For the strongly electronegative fluorine, already very small spin densities result in significant hyperfine couplings, so that fluorine nuclei in the neighborhood of a spin probe can be readily detected (21).
