This work describes a method for fabrication of extensive ordered arrays of microelectrodes with varied geometries, surrounded either by an insulating surface of poly(methyl methacrylate) (PMMA) or by a conductive material such as gold or glassy carbon (GC). The method is based on procedures from electron beam lithography (EBL) but, in contrast to classic EBL, it can be applied by using widely available conventional SEM instruments that are not specifically tailored for EBL operation. The electron gun of the SEM is used to irradiate and modify a PMMA film that is covered by a micro- or nano-structured mask (i.e., a TEM grid), which is further selectively revealed. Each array can be evaluated in two configurations, when it is surrounded by the PMMA film, and when it is in contact with the exposed support after PMMA removal. The first configuration is useful to evaluate the electrochemical behavior of pure microelectrode arrays for correlating it with model equations. The second configuration is particularly useful when the substrate material by itself is inactive for the studied reaction. In the latter case, any detected differences between the electrochemical behavior of the PMMA-coated array and that of the bi-component array should come from the contributions of the microelectrode boundaries. These arrays were employed for studying the hydrogen oxidation reaction in alkaline medium on Au/Rh and on GC/Rh in order to detect possible kinetic interactions of both components at the heterojunctions.

Career opportunities within science and technology are seeing unprecedented growth across the world, Formula: C14H6FeO2, and those who study chemistry or another natural science at university now have increasingly better career prospects. In a patent，Which mentioned a new discovery about 1273-94-5

We report about a series of mono-nuclear and bi-nuclear complexes with acyclic as well as macro-cyclic ligands, which have been synthesized with Schiff base ligands in tri- tetra and pentadentate forms. The bonding sites on complex formation are mainly the azomethine groups and/or imide nitrogen, ketonic oxygen or sulphur atoms. Complexes of two series of Schiff base ligands, H 2 La and H2 Lb derived from the reaction of 2,6-diacetyl pyridine with semicarbazide, replaced by or thiosemicarbazide with the metal ions, Co(II), Ni(II), Cu(II), VO(IV) and UO2(VI) have been prepared. Mono-nuclear complexes with tetradentate macrocyclic Schiff base ligands, derived from the condensation of 1,1?-diacetylferrocene with 1,3-diaminopropanein in the molar ratio 1:1 and 1:2 have been also synthesized and react with the transition metal ions, copper(II), nickel(II), cobalt(II), and Zinc(II) in the molar ratio 1:1. The structures of these ligands as well as the related complexes are elucidated by different spectroscopic methods. Solvatochromic behavior of copper(II) mixed ligand complexes of 3-acetylcoumarine (3-ACoum) and dinitrogen bases (L), with the general formula Cu(3-ACoum)(L)Xn; where n = 2, L = N,N,-Rfnet-temp?, N?-tetramethylethylenediamine (tmen), 1,10-phenanthroline (phen), 2,2?-bipyridine (bipy) and X = ClO 4-, BF4- or NO3- their synthesis and characterization by elemental analysis, IR, UV-Vis, electron spin resonance spectra, magnetic susceptibility and conductivity measurements is reported. The d-d absorption bands of tmen-complexes in weak donor solvents show the formation of square planar or square pyramidal geometries, whilst the strong donor solvents yield octahedral complexes. The observed solvatochromism is mainly due to the solute-solvent interaction between the chelate cation and the solvent molecules and the spectra displayed the possibility of using these complexes as Lewis base indicators. The Coats-Redfern equation can be used to calculate the kinetic and thermodynamic parameters for the different thermal decomposition steps of some complexes. Cyclic voltagrammes of Co(II) and Ni(II) show quasi-reversible peaks and characterize the redox properties and the nature of the electroactive species of the complexes. Biochemically, both the ligands and the complexes show growth inhibitory activity against pathogenic bacteria and plant pathogenic fungi.

Despite the fact that multiple artemisinin-alkylated proteins in Plasmodium falciparum have been identified in recent studies, the alkylation mechanism and accurate binding site of artemisinin-protein interaction have remained elusive. Here, we report the chemical-probe-based enrichment of the artemisinin-binding peptide and characterization of the artemisinin-binding site of P. falciparum translationally controlled tumor protein (TCTP). A peptide fragment within the N-terminal region of TCTP was enriched and found to be alkylated by an artemisinin-derived probe. MS2 fragments showed that artemisinin could alkylate multiple amino acids from Phe12 to Tyr22 of TCTP, which was supported by labeling experiments upon site-directed mutagenesis and computational modeling studies. Taken together, the “capture-and-release” strategy affords consolidated advantages previously unavailable in artemisinin-protein binding site studies, and our results deepened the understanding of the mechanism of protein alkylation via heme-activated artemisinin.

Recommanded Product: 1,1′-Diacetylferrocene, With the volume and accessibility of scientific research increasing across the world, it has never been more important to continue building the reputation for quality and ethical publishing we’ve spent the past two centuries establishing.In an article, 1273-94-5, molcular formula is C14H6FeO2, belongs to iron-catalyst compound, introducing its new discovery.

A chromotropic ferrocenyl chalcone with two pyrenyl groups (Fc-dPyr) is prepared and spectroscopically characterized. The X-ray structure analysis shows that the two pyrenyl groups are almost parallel to each other with a torsion angle of 5.57 and adopt a dimeric mode with a distance of 3.776 A? between them, ready to form an excimer. The solvatochromic fluorescence spectra indicate that the emission maxima observed in hydrogen-bonding donor (HBD) solvents (CHCl3, EtOH and MeOH) exhibit a strictly linear relationship with the normalized ETN value, while those in a non-HBD solvent (CH3CN) do not. The molecular chemosensor activity of Fc-dPyr is highly selective toward Fe(III) ions over Fe(II) ions. The fluorescence emission intensity of Fc-dPyr steeply decreases in the presence of Fe(III) ions as an oxidant, but not in the presence of Fe(II) ions.

Two types of transformations (the metal complex protonation and oxidation) have been revealed in the ferrocenylmethanol??2?2??? system (HX = HClO4, CF3COOH) by means of electronic spectroscopy. The efficiency of protonation has been determined from the intensity of the FcCH2 + carbocation absorption band (lambdamax = 600 nm); it depends on the acid strength and relative concentration as well as the solvent nature. Kinetics of ferrocenylmethanol oxidation in dioxane has been studied in the presence of trifluoroacetic acid. Two alternative reaction mechanisms have been proposed, differing in the coordination type of the reagents.

An ultrasensitive sandwich-type electrochemical biosensor for microRNA (miRNA) detection is developed based on magnesium oxide (MgO) nanoflower and graphene oxide?gold nanoparticles (GO?AuNPs) hybrids coupling with electrochemical?chemical?chemical (ECC) detection system. In this bioassay system, MgO nanoflowers and AuNPs are modified on electrode to act as sensing platform. The thiolated capture probe is then self-assembled onto AuNPs/MgO substrate via formation of Au-S bonds. Subsequently, a biotinylated DNA signal probe is conjugated to GO?AuNPs hybrids. When miRNA-21 is added, a sandwich complex is formed and a lot of signal indicators streptavidin-conjugated alkaline phosphatases (SA-ALP) are immobilized upon electrode by the specific reaction between avidin and biotin. Finally, ECC reaction is performed in the system to improve detection signal. The proposed sandwich-type assay benefits from advantages of sandwich-type structure for enhanced sensitivity and specificity, MgO nanoflowers/AuNPs as sensing platform and GO?AuNPs hybrids as signal carriers for signal amplification, and ECC as a sensitive detection system for low detection limit. This biosensor exhibits a good dynamic ranging from 0.1 to 100 fM and a low detection limit of 50 aM (S/N = 3) toward target miRNA-21.

An efficient system for the catalytic redox isomerization of the allylic alcohol 1-octen-3-ol to 3-octanone is presented. The homogeneous ruthenium(II) catalyst contains a monodentate phosphane ligand with a ferrocene moiety in the backbone and provides 3-octanone in quantitative yields. The activity is increased by nearly 90 % with respect to the corresponding triphenyl phosphane ruthenium(II) complex. By grafting the catalyst at the surface of a dendrimer, the catalytic activity is further increased. By introducing different spacers between ferrocene and phosphorus, the influence on the electronic properties of the complexes is shown by evaluating the electrochemical behavior of the compounds.
