“…From 2006 onwards, much literature has been published exploring a wide range of possibilities for the application of such materials. 2–4 The enhanced electrical and thermal conductivity, large surface area, higher charge mobility and carrier concentration, and mechanical strength of graphene materials allows their many applications in prototypes within sensing and energy storage technologies. 5–8 A broad range of possible technological applications vary from the manufacturing of supercapacitors, 9–15 dye-sensitised solar cells, 16,17 biological molecule sensors, 18,19 and catalyst supports, 20 to the field of nano-medicine using pristine graphene or graphene materials.…”

“…The length of arms (alkyl chains) is here in C 7 or C 8 , aims in view of flexibility. Until now, the grafting of pyridine and BiPy [46,47] has been successfully achieved. Any other adaptation pathways applicable to BiPy coverage is quite certainly conceivable.…”

“…Any other adaptation pathways applicable to BiPy coverage is quite certainly conceivable. The immobilization of mono-dentate ligands (like triphenyl phosphine) is at present in progress [47]. under quite similar conditions (stocking of energy with insertion of ions, highly reducing species, nucleophilic properties), and quite certainly opens new possibilities in the field of catalysis under accessible experimental conditions (Chapters 18 and 19).…”

The word "catalytic" comes from Ancient Greek and can be translated as "a breaking down". The word "catalysis" was introduced in the first half of the 19 th century by the Swedish Scientist J. J. Berzelius who applied it to the observation that in chemical reactions, the normal barriers can be removed by the help of external reagents. Nowadays, the term "catalysis" remains attached to the petroleum refining science introduced more than half a century ago. It mainly refers to the removal of sulfur and nitrogen from naphthas in order to produce fuel (gasoline, diesels, etc.). Refining reactions are conducted in the presence of catalysts often constituting of metals and metal oxides (mixed metal oxides, MMOs) in order to decrease cracking temperatures and improve selectivity of chemical reactions [1,2].In electro-chemistry, the term catalysis is quite recent and remains mainly linked to an easiness in interfacial reactions. Therefore, for It may then appear that most of the 19 chapters that follow this introduction possess an undeniable character of novelty both in the domain of new catalytic reactions, the chemical and electrochemical modifications of conducting solid surfaces, especially in the field of carbons, precious metals and copper. It is obvious however that some parts of the book could present a superficial or unbelievable aspect since both the ideas and the significant results do not go sufficiently into enough details about the scientific aspect and the possible applications. It could actually be the responsibility of the reader to freely reproduce some results and use some ideas (good or judged as incomplete) presented in this research.Among the well-established electro-catalytic processes, redox catalysis remains an intriguing and powerful method that specifically belongs to organic electro-chemistry. This technique 3 corresponds to the innovative and important progress in the field of indirect electrolyses. The first evidence of the indirect reduction of an alkyl-halide RX by the anion radical of naphthalene was reported by Fry [3] while the wide scope of redox catalysis (kinetics and synthetic applications) was unambiguously disclosed by Lund and co-workers [4-6, 8, 16] in the course of 1970s by using polarographic currents of Koutecky's theory. Meanwhile, other authors were also interested in this form of catalysis [7,9,10]. Based on this indirect process, kinetic and thermodynamic results were successfully achieved by by using the voltammetric technique. Thus, for the first time, thermodynamic data and standard potential values concerning reduction of R • radicals (issued from the cleavage of alkyl and aryl halides, (RX's and ArX's)) were appreciated in this way. Thus, RIs (alkyl iodides) in general and certain RBrs (alkyl bromides) may lead to one-electron scissions at cathodes. Therefore, selective one-electron processes and subsequently produced free radicals were considered to be of high interest also for synthesis and they prompted many authors in the course of last three decades to revi...

“…5, less tightly held electrons in the molecule (HOMO) lie mainly on the 5-membered ring contains N and S atoms (aminothiazolyl moiety), whereas LUMO, which will be the easiest route to the addition of electrons to the molecule, is located around carboxylic and etheric oxygens. Aminothiazolyl groups are known to be oxidized by 1 electron, dimerization occurs and related mechanisms are postulated in the literature (Jouikov and Simonet, 2007). The reported oxidation mechanism is irreversible which is initiated by removal of proton from the 5-membered ring and followed by a transfer of electron and finally dimerization.…”

Electrochemical behavior of cefditoren pivoxil (CTP) was studied via experimental electrochemical methods and theoretical calculations performed at B3LYP/6-31+G(d)//AM1 level. Experimental studies were carried out based on an irreversible 4eÀ/4H+ reduction peak at ca. À0.8 V on hanging mercury drop electrode (HMDE) and irreversible 1eÀ/1H+ oxidation of CTP at ca. 0.8 V on glassy carbon electrode (GCE) versus Ag/AgCl, KCl (3.0 M) in Britton-Robinson buffer at pH 6.0 and 4.0, respectively. Tentative reduction and oxidation mechanisms were proposed based on computational and experimental results. Square-wave adsorptive stripping voltammetric methods have been developed and validated for quantification of CTP in different samples. Linear working range was established as 0.15-15.0 lM for HMDE and 1.0-50.0 lM for GCE. Limit of quantification (S/N = 10) was calculated to be (0.10 ± 0.02) lM and (0.80 ± 0.03) lM for HMDE and GCE, respectively. Methods were successfully applied to assay the drug in tablets and human serum with good recoveries between (99.2 ± 11.6) % and (102.5 ± 9.5) % having relative standard deviation less than 10%. ª 2014 Production and hosting by Elsevier B.V. on behalf of King Saud University.
