Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 1119-97-7, molcular formula is C17H38BrN, introducing its new discovery. Recommanded Product: MitMAB

We propose an efficient and clean avenue for ammonia synthesis, via electroreduction of nitrate which could be obtained from industrial wastewater, domestic sewage, sodium nitrate ore, and nitrification of bacteria and electrochemical oxidation of nitrogen, which addresses the water pollution issues and simultaneously upgrades the nitrate to high-value ammonia. At a low overpotential of ?0.15 V versus RHE, Cu nanosheets achieved an ammonia formation rate of 390.1 mug mg?1 Cu h?1 and a Faradaic efficiency of 99.7%, attributed to suppression of the HER activity and apparent improvement of the rate of rate-determining step on Cu (111). Such an ammonia formation rate is more than two orders of magnitude higher than electrochemical nitrogen reduction reaction to ammonia. This work not only develops a powerful strategy to the rational design of robust and efficient catalysts by crystal facet engineering, but also provides an alternative route for electrochemical ammonia synthesis by reduction of nitrate.

Polyoxomolybdate-surfactant hybrid layered crystals were synthesized by using single-tailed alkyltrimethylammonium ([CnH2n+1N(CH3)3]+ (Cn), n = 8, 10, 12, 14, 16, and 18) cations. The crystal structures consisted of alternate stacking of octamolybdate ([Mo8O26]4-, Mo8) anionic layers and surfactant cationic layers. The layered distance of the hybrid crystals became longer from 18.5 A to 26.5 A with an increase in alkyl chain length. Interestingly, the molecular structures of Mo8, which has several isomers, depended on the alkyl chain length of the employed surfactants. Shorter surfactant (C8 and C10) formed hybrid crystals containing beta-type Mo8 isomer, while surfactant with longer alkyl chain (C12, C14, C16, and C18) gave crystals containing delta-type Mo8 isomer. This structural controllability will lead to the precise functional control in the polyoxomolybdate-surfactant hybrid layered crystals.

A previously elaborated capillary electrophoresis (CE) method used for the determination of glyphosate and aminomethylphosphonic acid (AMPA) was slightly modified in order to improve the sensitivity. However, detection limits attained (5 mug mL-1 for glyphosate and 4 mug mL-1 for AMPA) were still not satisfactory for analytical purposes, thus the addition of a preconcentration step before the CE analysis was proposed. AMBERLITE IRA-900, a strong anion-exchange resin, was used to preconcentrate both analytes in environmental aqueous samples. The experimental conditions optimised in a previous work were readapted, by decreasing the eluent concentration due to CE limitations. Satisfactory results were attained when spiked ultrapure water was applied, with recoveries from 84 to 87% for glyphosate (R.S.D. < 6%) and from 85 to 98% for AMPA (R.S.D. < 5%). Enrichment factors up to 65 were achieved with this system, allowing the determination of 85 ng mL-1 of glyphosate and 60 ng mL-1 of AMPA. The extraction efficiency varied when four different natural water samples of varying conductivity were applied. Especially the strong dependence on ion concentration in samples on AMPA recovery was found. For glyphosate, good recoveries (86-99%) were obtained for samples of low and medium conductivity (0-800 muS). The effect of sample salt content on extraction efficiency was studied and a linear relationship could be established for AMPA (r2 = 0.996). An important improvement on recoveries was observed when lower volumes of sample were treated. A HPLC method with UV-vis detection and pre-column derivatisation with p-toluensulphonyl chloride was compared to the CE method. No significant differences in results were found when t- and F-statistical tests were applied.

Quaternary derivatives of lysosomotropic substances (QDLS) are compounds belonging to the group of esterquats which exhibit both surface properties as well as special biological activity. In view of the biological application of these types of esterquats and/or their mixtures, it is necessary to carry out research in the cellular environmental conditions. Living organisms constitute an environment rich in various electrolytes. In turn, the presence of an electrolyte strongly influences the surface properties of QDLS and their biological activity. Therefore, the aim of the study was to analyze the adsorption properties of quaternary ammonium bromides from the group of esterquats and their mixtures in air-electrolyte systems. The electrolytes studied were four different sodium salts, as their use would allow determination of the effect of anion of electrolyte on adsorption properties of substances investigated. The measurements were performed at two temperatures: 21. C and 36.6. C. The results obtained indicate that both, addition of salt and temperature rise led to improved surface activity and accelerated the adsorption process of QDLS at the air-electrolyte interface. However, the enhancement of adsorption properties observed is affected by the type of anion added as well as its concentration.

Cyclic voltammetry investigation has been performed for the binary mixtures of tetradecyltrimethylammonium bromide (TTAB), hexadecyltrimethylammonium bromide (HTAB), and polyoxyethylene(23)laurylether (Brij 35), with triblock polymers, Pluronic L64 and F127, by using 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) as an electroactive probe at 25C. A variation in the peak current versus the total concentration of surfactant allowed us to evaluate the critical micellar concentration (cmc) and related parameters from regular solution theory along with the diffusion coefficient of the electroactive species. A variation in the micellar mole fraction of the ionic component suggests that the mixed micelles are rich in triblock polymer component in the ionic surfactant rich region of the mixture and vice versa. The regular solution interaction parameter (beta) indicates the formation of mixed micelles due to synergistic interactions which have been found to be more intense in the combinations of F127 rather than that of L64.

The anaerobic biodegradability and toxicity to methanogenic gas production of different alkyl chain length homologs of quaternary ammonium based surfactants were examinated. Two series of these cationic surfactants were selected: alkyl trimethyl ammonium and alkyl benzyl dimethyl ammonium compounds. A simple anaerobic gas production test containing municipal digester solids as a source of anaerobic bacteria was used. Under the applied methanogenic conditions, the cationic surfactants tested showed a very poor primary biodegradation and no evidence of any extent of ultimate biodegradation was observed. The toxicity of quaternary ammonium based surfactants to methanogenic gas production decreased with increasing the alkyl chain length.

We characterized the potent in vitro antimalarial activity and biologic assessment of 13 phospholipid polar head analogs on a comparative basis. There was a positive relationship between the abilities of the drugs to inhibit parasite growth in culture and their abilities to specifically inhibit phosphatidylcholine biosynthesis of Plasmodium falciparum-infected erythrocytes. Maximal activity of G25 was observed for the trophozoite stage of the 48-h erythrocytic cycle (50% inhibitory concentration, 0.75 nM), whereas the schizont and ring stages were 12- and 213-fold less susceptible. The compounds exerted a rapid nonreversible cytotoxic effect, with complete clearance of parasitemia after 5 h of contact with the mature stages. The compounds were highly specific against P. falciparum, with much lower toxicity against three other mammalian cell lines, and the in vitro therapeutic indices ranged from 300 to 2,500,000. Finally, the monoquaternary ammonium E10 and two bis-ammonium salts, G5 and G25, were similarly active against multiresistant strains and fresh isolates of P. falciparum. This impressive selective in vitro toxicity against P. falciparum strongly highlights the clinical potential of these quaternary ammonium salts for malarial chemotherapy.

We identified a novel plasmid-borne gene (designated qacJ) encoding resistance to quaternary ammonium compounds (QACs) in three staphylococcal species associated with chronic infections in four horses. qacJ was located on a 2,650-bp plasmid (designated pNVH01), a new member of the pC194 family of rolling-circle replication plasmids. The 107-amino-acid protein, QacJ, showed similarities to known proteins of the small multidrug resistance family: Smr/QacC (72.5%), QacG (82.6%), and QacH (73.4%). The benzalkonium chloride MIC for a qacJ-containing recombinant was higher than those for otherwise isogenic recombinants expressing Smr, QacG, or QacH. Molecular epidemiological analyses by pulsed-field gel electrophoresis suggested both the clonal spread of a qacJ-harboring Staphylococcus aureus strain and the horizontal transfer of pNVH01 within and between different equine staphylococcal species. The presence of pNVH01 of identical nucleotide sequence in different staphylococcal species suggests that recent transfer has occurred. In three of the horses, a skin preparation containing cetyltrimethylammonium bromide had been used extensively for several years; this might explain the selection of staphylococci harboring the novel QAC resistance gene.
