Examples of Using CATIONIC in a Sentence

• The result is a neutral sheet: with aluminium as a +3 ion and hydroxide a −1 ion, the net cationic charge of one aluminium per six hydroxides is (+3)/6 = +1/2, and likewise the net anionic charge of one hydroxide per two aluminium atoms is (−1)/2 = −1/2.
• In this context, leaving groups are generally anions or neutral species, departing from neutral or cationic substrates, respectively, though in rare cases, cations leaving from a dicationic substrate are also known.
• Benzalkonium chloride (BZK, BKC, BAK, BAC), also known as alkyldimethylbenzylammonium chloride (ADBAC) and by the trade name Zephiran, is a type of cationic surfactant.
• Brown of Purdue over the existence of so-called "nonclassical" carbocations – such as the norbornyl cation, which can be depicted as cationic character delocalized over several bonds.
• The Coomassie brilliant blue G-250 dye exists in three forms: anionic (blue), neutral (green), and cationic (red).
• Most commonly the more electronegative atom keeps the pair of electrons becoming anionic while the more electropositive atom becomes cationic.
• Furthermore, the catalytic and organometallic studies on Wilkinson's catalyst also played a significant role on the subsequent development of cationic Rh- and Ru-based asymmetric hydrogenation transfer catalysts which set the foundations for modern asymmetric catalysis.
• Conway was elected a Fellow of the Royal Society in 1947, his application citation stating that he was "Distinguished for investigations of chemical and physiochemical processes in living tissues, including a quantitative interpretation of the processes underlying potassium accumulation in isolated muscle, with applications to resting potentials and related questions; the exact determination of blood ammonia, the ammonia increase in shed blood, and studies of the deaminase involved; general structural relations of the mammalian kidney, and studies of diffusion rates through tissues; biochemical studies of yeast fermentation in relation to cationic exchanges and production of free hydrochloric acid; bio-geochemical study of oceanic evolution; new methods of micro-diffusion analysis".
• These special anions are essential components of homogeneous alkene polymerisation catalysts, where the active catalyst is a coordinatively unsaturated, cationic transition metal complex.
• Here the two binding sites are a benzidine and a biphenol unit; the cationic ring typically prefers staying over the benzidine ring, but moves over to the biphenol group when the benzidine gets protonated at low pH or if it gets electrochemically oxidized.
• The equilibrated stationary phase consists of an ionizable functional group where the targeted molecules of a mixture to be separated and quantified can bind while passing through the column—a cationic stationary phase is used to separate anions and an anionic stationary phase is used to separate cations.
• Mutations in the ion channel domain of a neuronal nicotinic receptor convert ion selectivity from cationic to anionic.
• Their amino acid composition, amphipathicity, cationic charge and size allow them to attach to and insert into membrane bilayers to form pores by ‘barrel-stave’, ‘carpet’ or ‘toroidal-pore’ mechanisms.
• Pauling used effective nuclear charge to proportion the distance between ions into anionic and a cationic radii.
• As an nonionic monomer it can be co-polymerize with anionic for example Acrylic acid and cationic monomer such as diallyldimethyl ammonium chloride (DADMAC) and resulted co-polymer that can have different compatibility in different applications.

• The biosynthesis of longifolene begins with farnesyl diphosphate (1) (also called farnesyl pyrophosphate) by means of a cationic polycyclization cascade.
• Structures that stain with aluminium-hematein (haemalum) are often said to be basophilic, but the staining mechanism is not as simple as for basic (cationic) dyes with smaller molecules.
