Ammonium bromide was recently found to have a high FR-effectivity of bromine, i.e. 1.24 for NH4Br encapsulated in PP as compared to 0.6 for aliphatic bromine compounds. It has been explained by the low dissocia
STABLE BROMINE CHARGE STORAGE IN POROUS CARBON ELECTRODES USING TETRAALKYLAMMONIUM BROMIDES FOR REVERSIBLE SOLIDCOMPLEXATIONElectrolytes for use in electric double-layer capacitors (EDLCs; often referred as supercapacitors or ultracapacitors) are disclosed. In one example, the electrolyte comprises viologen ...
where the carbonyl group and the halogen atom were both activated by TEMPO+catalysis. TEMPO+has short N–O distance with halogenating reagent, positive charge on the Cl atom, and low

Identify the symbol and charge of the ions in this compound. Write the correct name for the compound NH3. Give the formula for the compound formed from the cation NH4+ and the anion ClO3-. What is the chemical formula for the compound formed between Ba and I? Write formulas for ...
1H NMR was used to confirm the chemical structure of Br-PAEK and to determine the degree of bromine substitution (DBr) of the polymer backbones. As shown in Fig. 1, the chemical shifts Conclusions In this study, poly(arylene ether ketone) containing methyl groups on aromatic rings was ...
A possible mechanism of hormetic effect was analyzed based on the molecular structures of these five QACs on the luciferase in Q67. The hormetic effect of these five compounds may be related to the “alkyl chain effect” and halogen (chlorine or bromine) anions. Therefore, it was assumed that...
It is preferred that R4 represents hydrogen, since such compounds can be isolated as internal salts, which have a phenoxide anion to balance the positive charge on the quaternized nitrogen. It is also preferred that R4 represents alkylcarbonyl, straight or branched, having from two to five ...
Water-soluble random copolymer ammonium ionenes with in the range of 17.4 to 20.8 kg mol1 and various charge densities are synthesized from 1,12-dibromododecane, N,N,N,N-tetramethyl-1,6-hexanediamine, and 1,12-bis(N,N-dimethylamino)dodecane. Anion exchange of the bromine counterion forms ...
Anion exchange of the bromine counterion forms ionenes with TFSI, TFO, and BF 4 anions. The nature of the counteranion and charge density tailor the thermal and rheological properties of 12,6/12-ionenes, respectively. X-ray scattering reveals microphase separation with a correlation length of ≈...
