Salt-assisted ultrasonicated de-aggregation and advanced redox electrochemistry of detonation nanodiamond

Nanodiamond particles form agglomerates in the dry powder state and this poses limitation to the accessibility of their diamond-like core thus dramatically impacting their technological advancement. In this work, we report de-agglomeration of nanodiamond (ND) by using a facile technique namely, salt-assisted ultrasonic de-agglomeration (SAUD). Utilizing ultrasound energy and ionic salts (sodium chloride and sodium acetate), SAUD is expected to break apart thermally treated nanodiamond aggregates (~50-100 nm) and produce an aqueous slurry of de-aggregated stable colloidal nanodiamond dispersions by virtue of ionic interactions and electrostatic stabilization. Moreover, the SAUD technique neither has toxic chemicals nor is it difficult to remove impurities and therefore the isolated nanodiamonds produced are exceptionally suited for engineered nanocarbon for mechanical (composites, lubricants) and biomedical (bio-labeling, biosensing, bioimaging, theranostic) applications. We characterized the microscopic structure using complementary techniques including transmission electron microscopy combined with selected-area electron diffraction, optical and vibrational spectroscopy. We immobilized SAUD produced NDs on boron-doped diamond electrodes to investigate fundamental electrochemical properties. They included surface potential (or Fermi energy level), carrier density and mapping electrochemical (re)activity using advanced scanning electrochemical microscopy in the presence of a redox-active probe, with the aim of understanding the surface redox chemistry and the interfacial process of isolated nanodiamond particles as opposed to aggregated and untreated nanoparticles. The experimental findings are discussed in terms of stable colloids, quantum confinement and predominantly surface effects, defect sites (sp2-bonded C and unsaturated bonds), inner core (sp3-bonded C)/outer shell (sp2-bonded C) structure, and surface functionality. Moreover, the surface electronic states give rise to midgap states which serve as electron donors (or acceptors) depending upon the bonding (or antibonding). These are important as electroanalytical platforms for various electrocatalytic processes.

Improvement of the amperometric response to l-lactate by using a cationic bioinspired thymine polycation in a bioelectrode with immobilized lactate oxidase

We report the electroanalytical properties of an amperometric bioelectrode containing l-lactate oxidase (LOx) immobilized on glassy carbon electrode with a hydrogel film composed of laponite and different amounts of a novel bioinspired polycation obtained by copolymerization of 4-vinylbenzyl thymine (VBT) and 4-vinylbenzyl triethylammonium chloride (VBA) in a molar ratio 1:4, respectively. The electrochemical behavior of the redox couple probe [Fe(CN)6]3-/4- of these VBT-VBA bioelectrodes was compared with that observed for a bioelectrode containing the classical polycation polydiallyldimethylammonium chloride (PDDA). The best response was obtained for a bioelectrode containing a VBT-VBA/laponite mass ratio double than the cationic exchange capacity of the clay, demonstrating that under this condition the polycation induces an optimal microenvironment in the interlamellar space of the clay, both for the position and the functionality of LOx. The VBT-VBA bioelectrode displayed a very high sensitivity (7.2 ¡À 0.2) ¡Á 102 muA mM-1 cm-2, a short time response (<5 s), a wide linear response range (e.g. 0.01-1.0 mM of l-lactate) and an excellent stability over a storage period of 60 days, when sensing l-lactate. The analytical response of the bioelectrode was tested in real food samples, e.g. milk, white wine, and beer, as well as during milk fermentation at 37 C. No effect of molecular interferences in the food matrices was detected, and the quantification of l-lactate was in complete agreement with standard assays reported values. Current results indicate that polycations containing the multifunctional green monomer VBT have high potential for their use in hydrogel film formation producing more responsive and stable electrochemical biosensors.

Organometallic Derivatization of the Nematocidal Drug Monepantel Leads to Promising Antiparasitic Drug Candidates

The discovery of novel drugs against animal parasites is in high demand due to drug-resistance problems encountered around the world. Herein, the synthesis and characterization of 27 organic and organometallic derivatives of the recently launched nematocidal drug monepantel (Zolvix) are described. The compounds were isolated as racemates and were characterized by1H,13C, and19F NMR spectroscopy, mass spectrometry, and IR spectroscopy, and their purity was verified by microanalysis. The molecular structures of nine compounds were confirmed by X-ray crystallography. The anthelmintic activity of the newly designed analogues was evaluated in vitro against the economically important parasites Haemonchus contortus and Trichostrongylus colubriformis. Moderate nematocidal activity was observed for nine of the 27 compounds. Three compounds were confirmed as potentiators of a known monepantel target, the ACR-23 ion channel. Production of reactive oxygen species may confer secondary activity to the organometallic analogues. Two compounds, namely, an organic precursor (3 a) and a cymantrene analogue (9 a), showed activities against microfilariae of Dirofilaria immitis in the low microgram per milliliter range.

alpha-ferrocenylalkylation of 1,5-disubstituted tetrazoles and certain transformations of reaction products

The reaction of alpha-hydroxyferrocenylalkyl derivatives and vinylferrocene with 1,5-disubstituted tetrazoles in methylene chloride-aqueous acid HX (X = BF4, ClO4) two-phase systems gives a mixture of 1,3,5- and 1,4,5-trisubstituted tetrazolium salts, the fraction of the 1,3,5-isomers prevailing. The synthesized salts are readily dealkylated under the action of bases to give the above starting compounds. Heating of 3(4)-(ferrocenylmethylene)-1,5-pentamethylenetetrazolium and 3(4)-(ferrocenylmethylene)-2-methyl-1-phenyltetrazolium tetrafluoroborates in anhydrous methanol or ethanol in the presence of catalytic amounts of alkali gives rise to ferrocenylcarbinol ethers. Other nuclephiles (pyridine, triphenylphosphine, sodium thiocyanate, sodium p-toluenesulfinate, dibenzoylmethane) also react with the above tetrazolium salts, forming ferrocenylmethylation products. Heating of equimolar amounts of 3(4)-(ferrocenylmethylene)-1,5-pentamethylenetetrazolium or 3(4)- (ferrocenylmethylene)-2-methyl-1-phenyltetrazolium perchlorates with mercury(II) perchlorates in anhydrous ethanol results in mercuration of the starting tetrazolium salts, involving hydrogen substitution in the methylene or methyl groups bound to tetrazolium carbon atoms. The condensation of the same salts with p-N,N-(dimethylamino)nitrosobenzene, leading to azomethine formation, occurs under similar conditions.

Novel Synthetic Method for Magnetic Porous Carbon Materials for Efficient Adsorption of Organic Pollutants from Aqueous Solution

A novel method for the preparation of magnetic porous carbon materials (MPMs) with high specific surfaces was developed using hydroxymethylferrocene through the combination of chloromethylation, hypercross-linked polymerization, and vacuum carbonization. The MPMs were mainly composed of porous carbon and iron nanoparticles. The specific surface and maximum specific saturation magnetization of MPMs were 295.90 m2/g and 7.45 emu/g, respectively. Furthermore, organic dyes, organic pesticides, and antibiotics were chosen as model adsorbates to test the adsorption properties of MPMs. The adsorption capacity of MPMs for methyl red was up to 199.54 mg/g at 120 min, and the adsorption isotherm was proved to fit the Langmuir isotherm model. The reuse results confirmed that MPMs had an excellent regenerative capacity and reusability stability. Moreover, MPMs showed superior removal efficiency for the rice field pesticides (emamectin benzoate, imidacloprid) and antibiotics (ampicillin). The above observations demonstrated that MPMs were universal to organic pollutants and would be one of the most promising candidates in the water purification filed.

Simultaneous Multiplex Potentiostatic Electroanalysis with Liquid-Junction-Removed Reference Electrode System using a Closed Bipolar Electrode

A novel liquid-junction-removed reference electrode system was developed for simultaneous multiplex amperometry using a closed bipolar electrode. The liquid junction between the reference cell and the sample cell was replaced by a bipolar electrode to ensure electron conductivity in lieu of ionic conductivity in conventional systems. Under the condition where the redox reaction of the analyte at the bipolar electrode in the sample cell was a limiting process, voltammetric and amperometric measurements were performed for quantitative detection of the analytes. After characterization of the system, a chip-type device was fabricated with six sample cells and one reference cell. Simultaneous determination of ferrocene methanol was conducted in six solutions in the 0.1?0.5 mM range. This is the first demonstration of the simultaneous multiplex determination of analytes with a liquid-junction-removed system. Although the potential control problem (which is different to the liquid potential problem of conventional liquid junction) still remains because of the increase of the solid?liquid interface, this system is expected to solve some problems associated with the liquid junction of the reference electrode, including sample contamination by chloride ions and the complicated process of fabricating a reference electrode on a chip.

Homochiral arsenic-/phosphorus-based ligands

The synthesis of homochiral phosphorus-based ligands has escalated dramatically over the last decade in the drive to develop new, and further fine tune existing, base structures of chiral auxiliaries that have had, and most certainly are continuing to have, a phenomenal impact in the arena of enantioselective catalysis. This review highlights the vast array of homochiral phosphorus-based ligands and their significantly fewer arsenic-based analogs, the key synthetic strategies used to prepare them and the significant roles that they have been employed in after coordination to a transition metal center.

The stability of diazonium ion terminated films on glassy carbon and gold electrodes

Glassy carbon (GC) and Au electrodes were modified with aminophenyl films by electroreduction of the corresponding diazonium salt. Aminophenyl films were diazotised using both aqueous and non-aqueous conditions, to generate film-based phenyldiazonium ions. The stabilities of the diazonium terminated films, to exposure to air and in acidic solution, were investigated by cyclic voltammetry (CV). For films of the same thickness, those grafted to Au substrates are more stable than those grafted to GC.

3D-printed photo-spectroelectrochemical devices for in situ and in operando X-ray absorption spectroscopy investigation

Three-dimensional printed multi-purpose electrochemical devices for X-ray absorption spectroscopy are presented in this paper. The aim of this work is to show how three-dimensional printing can be a strategy for the creation of electrochemical cells for in situ and in operando experiments by means of synchrotron radiation. As a case study, the description of two cells which have been employed in experiments on photoanodes for photoelectrochemical water splitting are presented. The main advantages of these electrochemical devices are associated with their compactness and with the precision of the three-dimensional printing systems which allows details to be obtained that would otherwise be difficult. Thanks to these systems it was possible to combine synchrotron-based methods with complementary techniques in order to study the mechanism of the photoelectrocatalytic process.

Soap film electrochemistry

In this paper we present preliminary electrochemical investigations into the transport properties of free standing ultra-thin surfactant films and the associated meniscus. We describe a new electrochemical cell composed of a 25 mum diameter gold wire placed through a stable surfactant film which served as the electrolyte. Solutions containing anionic sodium dodecyl sulphate (SDS) or non-ionic Triton-X100 surfactants, with background electrolyte NaCl and with electroactive probe ferrocyanide or ferrocene methanol, were used to create the surfactant films. The electrolyte was an ultra-thin surfactant film creating a two dimensional solution with a thickness between 300 and 1000 nm, and its meniscus at the gold wire, within which the electroactive probe was free to diffuse. Cyclic voltammetry was used to oxidise and reduce the electroactive probe within the surfactant film and meniscus. It was shown that films and the associated meniscus formed from SDS solution almost completely excluded negatively charged ferrocyanide. A finite difference simulation showed that the voltammetry was dominated by the meniscus region, the unusual spatially-varying bounded geometry of which resulted in an unusual dependence on potential scan rate of the peak to peak separation (decreasing with increasing scan rate) and anodic:cathodic peak current ratio (increasing with increasing scan rate).
