To the best of our knowledge, this method has not been used for analyzing such reactive intermediates, but the results showed that ion 1‐Br+ displays similar hardness, or the lack thereof, as those of bromonium ions of the conjugated cyclohexenes included in this theoretical study, which was expected, and ions 7‐Br+ and 11‐ Br+, while somewhat harder than ion 1‐Br+, also displayed hardness values much lower than bromonium ions of non‐ conjugated mono‐alkenes included in this report. keywords: 11‐br+; bond; bromonium; bromonium ion; charge; compound; conjugation; cyclopropyl; hardness; ion; ions; nmr; reaction; ring; scheme cache: eurjchem-1307.pdf plain text: eurjchem-1307.txt item: #155 of 1199 id: eurjchem-1310 author: Islam, Muhammad; Shafiq, Zahid; Hussain, Mazhar; Ahmad, Hafiz Badaruddin; Hussain, Muhammad Ajaz title: Synthesis, characterization and antimicrobial studies of imine derivatives of amoxicillin date: 2015 words: 4107 flesch: 72 summary: Qin, W.; Panunzio, M.; Biondi, S.

substances behave according to these rules, in terms of electron  chemical bonds scission and formation.  Now,  pretending  that  empirical  rules  used  by  chemists  to  interpret  repeated observations  (such as  the  lack of  reactivity  of noble gas elements with heuristic concepts such as the octet  rule)  are  of  fundamental  nature,  may  easily  implicate  a  limitation  to  the  progress  of  chemistry;  as  the  case  of  the  delayed  discovery  of  xenon  compounds  (“forbidden”  by  the  octet rule) typically demonstrates. keywords: chemical; chemistry; chemists;

It was found that pure TiO2 exhibited photo- catalytic activity under the visible light irradiation, the reason might be that added C6H12N4 in the experiment not only provided an alkaline environment, meanwhile added C6H12N4 acted as the nitrogen source for nitrogen doping into TiO2, so the as-prepared TiO2 exhibited photocatalytic activity under visible light irradiation. keywords: composites; figure; irradiation; journal; tio2; zntio3 cache: eurjchem-1824.pdf plain text: eurjchem-1824.txt item: #430 of 1199 id: eurjchem-1825 author: Zaghary, Wafaa Abdou; Abdalla, Ahmed Mostafa; Hanna, Emily Tawfik; Shoukry, Nermeen Abdallah title: Application of multiple reaction monitoring for quantitation of sweeteners in food products date: 2019 words: 3111 flesch: 55 summary: Robustness of the method The robustness of an analytical method measures the capacity of the method to restrain minute but deliberate changes in method parameters [4].

Color changes of receptor 1 due to addition of F‐ ion. Therefore the acidic property of H of NH of imidazole moiety remarkably increased and binding ability of the receptors 1‐3 for anions remarkably increased accordingly, but for the receptors 2 and 3 the nitro group of m‐site or o‐site blocked binding of receptors 2 and 3 to bind with F‐. For the receptor 7‐9, the 4 and 5 sites of imidazole moiety have no phenyl ring and the acidic property of H of HN of imidazole moiety remarkably decreased, therefore they can’t bind anions. keywords: addition; anions; chem; fluoride; lett; receptor cache: eurjchem-189.pdf plain text: eurjchem-189.txt item: #466 of 1199 id: eurjchem-1895 author: Abd El-Moemen, Ayman title: Catalytic activity of nanosized Au/CeO2 catalyst towards H2O2 decomposition and the role of cationic/metallic ratio in its activity date: 2019 words: 4303 flesch: 66 summary: Pireaux, J.

Different solvents with various polarity were screened (Table 1) for the condensation reaction in the presence of catalyst and found that all the solvents studied afforded the products in excellent yields with a slight variation in reaction period (15‐60 min).

Photodegradation process occurred due to the adsorbing of drugs over TiO2 particles and the photodegradation is driven by injecting of an electron from excited state of drug into the conduction band of TiO2 particles which leads to the oxidation of drug molecules, also the electron of conduction band caused by moving the electrons from valence band and these electron may be used to drive another photoreactions of drug molecules in different routes.
