The surface interrogation mode of scanning electrochemical microscopy (SECM) is extended to the in situ quantification of adsorbed hydrogen, H ads, at polycrystalline platinum. The methodology consists of the production, at an interrogator electrode, of an oxidized species that is able to react with Hads on the Pt surface and report the amounts of this adsorbate through the SECM feedback response. The technique is validated by comparison to the electrochemical underpotential deposition (UPD) of hydrogen on Pt. We include an evaluation of electrochemical mediators for their use as oxidizing reporters for adsorbed species at platinum; a notable finding is the ability of tetramethyl-p-phenylenediamine (TMPD) to oxidize (interrogate) H ads on Pt at low pH (0.5 M H2SO4 or 1 M HClO4) and with minimal background effects. As a case study, the decomposition of formic acid (HCOOH) in acidic media at open circuit on Pt was investigated. Our results suggest that formic acid decomposes at the surface of unbiased Pt through a dehydrogenation route to yield Hads at the Pt surface. The amount of Hads depended on the open circuit potential (OCP) of the Pt electrode at the time of interrogation; at a fixed concentration of HCOOH, a more negative OCP yielded larger amounts of Hads until reaching a coulomb limiting coverage close to 1 UPD monolayer of H ads. The introduction of oxygen into the cell shifted the OCP to more positive potentials and reduced the quantified Hads; furthermore, the system was shown to be chemically reversible, as several interrogations could be run consecutively and reproducibly regardless of the path taken to reach a given OCP.

Chemistry is a science major with cience and engineering. The main research directions are preparation and modification of special coatings, and research on the structure and performance of functional materials. In a patent, 1273-86-5, name is Ferrocenemethanol, introducing its new discovery. Recommanded Product: Ferrocenemethanol

The ferrocene-derived acids FcCH2CH2E(O)(OH)2 [4, E=P; 10, E=As; Fc=Fe(eta5-C5H5)(eta5-C5H4)] have been synthesized by the reaction of FcCH2CH2Br with either P(OEt)3 followed by hydrolysis, or with sodium arsenite followed by acidification. Reaction of FcCH2OH with (EtO)2P(O)Na gave FcP(O)(OEt)(OH), which was converted to FcCH2P(O)(OH)2 (3) by silyl ester hydrolysis using Me3SiBr-Et3N followed by aqueous work-up. Similarly, the known phosphonic acid FcP(O)(OH)2 and the new derivatives 1,1?-Fc?[P(O)(OH)2]2 [Fc?=Fe(eta5-C5H4)2] and 1,1?-Fc?[CH2P(O)(OH)2]2 (7) have been synthesized via their corresponding esters. X-ray crystal structure determinations have been carried out on 3 and 7, and the hydrogen-bonding networks discussed. Electrospray mass spectrometry has been employed in the characterization of the various acids. Phosphonic acids give the expected [M-H]- ions and their fragmentation at elevated cone voltages has been found to be dependent on the acid. FcP(O)(OH)2 fragments to [C5H4PO2H]-, but in contrast Fc(CH2)nP(O)(OH)2 (n=1, 2) give Fe{eta5-C5H4(CH2)nP(O)O2]- ions, which are proposed to have an intramolecular interaction between the Fe atom and the phosphonate group. In contrast, arsonic acid (10), together with PhAs(O)(OH)2 for comparison, undergo facile alkylation (in methanol or ethanol solvent), and at elevated cone voltages (e.g. 60 V) undergo carbon-arsenic bond cleavage giving [CpFeAs(O)(OR)O]- (R=H, Me, Et) and ultimately [AsO2]- ions.

Integrated amperometric biosensors for the determination of l-malic and l-lactic acids were developed by coimmobilization of the enzymes l-malate dehydrogenase (MDH) and diaphorase (DP), or l-lactate oxidase (LOX) and horseradish peroxidase (HRP), respectively, together with the redox mediator tetrathiafulvalene (TTF), on a 3-mercaptopropionic acid (MPA) self-assembled monolayer (SAM)-modified gold electrode by using a dialysis membrane. The electrochemical oxidation of TTF at +100 mV (vs. Ag/AgCl), and the reduction of TTF+ at -50 mV were used for the monitoring of the enzyme reactions involved in l-malic and l-lactic acid determinations, respectively. Experimental variables concerning the biosensors composition and the detection conditions were optimized for each biosensor. Good relative standard deviation values were obtained in both cases for the measurements carried out with the same biosensor, with no need of cleaning or pretreatment of the bioelectrodes surface, and with different biosensors constructed in the same manner. After 7 days of continuous use, the MDH/DP biosensor still exhibited 90% of the original sensitivity, while the LOX/HRP biosensor yielded a 91% of the original response after 5 days. Calibration graphs for l-malic and l-lactic were obtained with linear ranges of 5.2 × 10-7 to 2.0 × 10-5 and 4.2 × 10-7 to 2.0 × 10-5 M, respectively. The calculated detection limits were 5.2 × 10-7 and 4.2 × 10-7 M, respectively. The biosensors exhibited a high selectivity with no significant interferences. They were applied to monitor malolactic fermentation (MLF) induced by inoculation of Lactobacillus plantarum CECT 748T into a synthetic wine. Samples collected during MLF were assayed for l-malic and l-lactic acids, and the results obtained with the biosensors exhibited a very good correlation when plotted against those obtained by using commercial enzymatic kits.

Air-stable primary phosphines were photopolymerized using phosphane-ene chemistry, the phosphorus analogue of the thiol-ene reaction, to fabricate a completely new class of polymer networks. It was demonstrated that the tunable thermal and physical properties accessible using thiol-ene chemistry could also be achieved using an analogous phosphane-ene reaction. At the same time, the presence of the 31P nucleus that is easily observed using NMR spectroscopy allowed the chemical structures of the networks to be directly probed using solid state NMR spectroscopy. Following its incorporation into the network, phosphorus offers the distinct difference and advantage of being able to undergo a diverse array of further derivatization to afford functional materials. For example, the networks were demonstrated to serve as effective oxygen scavengers and to bind transition metals (e.g., Pd). By using the air stable ferrocenyl phosphine (FcCH2CH2)PH2, redox-active networks were produced and these materials could be pyrolyzed to yield magnetic ceramics. Overall, this demonstrates the promise of phosphane-ene chemistry as an alternative to thiol-ene systems for providing functional materials for a diverse range of applications.

A new form of high surface area bioelectrode, based on nanofibers of electrospun gold with immobilized fructose dehydrogenase, was developed. The gold fibers were prepared by electroless deposition of gold nanoparticles on an electrospun poly(acrylonitrile)-HAuCl4 fiber. The material was characterized using electron microscopy, XRD and BET, as well as cyclic voltammetry and biochemical assay of the immobilized enzyme. The electrochemical surface area of the gold microfibers was 0.32±0.04m2/g. Fructose dehydrogenase was covalently coupled to the gold surface through glutaraldehyde crosslinks to a cystamine monolayer. The enzyme exhibited mediated electron transfer directly to the gold electrode and catalytic currents characteristic of fructose oxidation in the presence of a ferrocene methanol mediator were observed. The limit of detection of fructose was 11.7muM and the KM of the immobilized enzyme was 5mM. The microfiber electrode was stable over 20 cycles with a 3.05% standard deviation. The response time of the sensor was less than 2.2s and reached half maximum value within 3.6s. The sensor was proven to be accurate and precise in both serum and popular beverages sweetened with high fructose corn syrup. The addition of glucose isomerase enabled the sensor to perform with glucose, thus expanding the available analyte selection for the sensor.

This paper describes a simple and miniaturized microdroplet chip (muchip) that is constructed with a silica nanochannel (SNC)-assisted electrode array and a hydrophobic paper cover (SNC&P-muchip). Vertically aligned SNCs with uniform pore size of 2?3 nm in diameter and negatively charged surface can significantly accelerate the mass transport of the positively charged tris(2,2′-bipyridyl) ruthenium (II), resulting in a remarkably enhanced electrochemiluminescence (ECL) signal. The SNC-assisted electrode array was coupled to a low cost paper cover to achieve simultaneous detection of six samples in 1 min. The feasibility and universality of the SNC&P-muchip was evaluated by detecting a series of alkaloidal drugs both in buffers and in human serum. The performance of the SNC&P-muchip was fully validated with respect to linearity (0.9999 > R > 0.9939), sensitivity (limits of detection from 1.799 nM to 11.43 nM), and accuracy (recovery rate between 94.38% and 109.12%). The facile and economic SNC&P-muchip shows promising potential for rapid drug detection in complex biofluids.

A ferrocene-based compartmental ligand, H2L, was synthesized by the reaction of diacetyl ferrocene with hydrazine hydrate followed by a condensation reaction with o-vanillin. [L]2- possesses a dual coordination pocket, an inner pocket of 2 imino nitrogens and two phenolate oxygens and an outer pocket of two phenolate and two methoxy oxygen atoms. Utilizing this ligand, several ZnII/LnIII heterobimetallic complexes were assembled: [LZn(mu-OAc)Dy(NO3)2] (2), [LZn(mu-OAc)Tb(NO3)2] (3), [LZn(mu-OAc)Gd(NO 3)2·2CHCl3] (4), [LZn(mu-OAc) Er(NO3)2] (5), [LZn(mu-OAc)Ho(NO3) 2] (6), [LZn(mu-OAc)Eu(NO3)2] (7). All of these metal complexes are neutral and isostructural: the ZnII ion occupies the inner coordination pocket while the LnIII ion occupies the outer coordination pocket of the doubly deprotonated ligand [L] 2-. Zn(ii) has a coordination number of 5 (2N, 3O) in a square pyramidal coordination geometry while Ln(iii) has a coordination number of 9 (9O) in a distorted tricapped trigonal prismatic geometry. Zn(ii) and the 4f metal ion are bridged to each other by two phenolate oxygen atoms and an acetate ligand. ESI-MS reveals that 2-7 retain their structural integrity in solution. Cyclic voltammetry of 1-7 revealed a quasi-reversible oxidation (involving the ferrocene motif) and an irreversible reduction of the hydrazone unit. Magnetic studies of 2, 3 and 6 were carried out. Ac susceptibility studies did not reveal slow relaxation of magnetization.

A virus-based nanostructuring strategy is proposed for improving the catalytic performance of integrated redox enzyme electrodes. Random arrays of adsorbed filamentous fd bacteriophage particles, used as scaffolds, are assembled onto gold electrode surfaces. The viral particles are endowed with functionally coupled enzymatic and redox properties, by the sequential immunological assembly of quinoprotein glucose dehydrogenase conjugated antibodies and ferrocene PEGylated antibodies on their protein shell. The resulting virus-scaffolded enzyme/redox mediator integrated system displays a large enhancement in the catalytic current generated per enzyme molecule (i.e., in enzymatic turnover) as compared with nonscaffolded integrated glucose oxidizing enzyme electrodes. The mechanism underlying the observed scaffolding-induced catalytic enhancement is deciphered. Confinement of the mediator on the viral scaffold enables fast electron transport rate and shifts the enzyme behavior into its most effective cooperative kinetic mode.
