Titan, the largest satellite of Saturn, is a key planetary body for astrobiological studies due to its active organic chemistry, hydrocarbon lakes and possible subsurface water-ammonia liquids. We have investigated the physicochemical properties of organic compounds synthesized in a simulated Titan atmosphere. A laboratory analog of Titans aerosols, called tholin, was produced by irradiation of a nitrogen/methane gas mixture. The primary aim was to determine whether tholin represent possible sources of surface-active substances that could have been involved in the formation of prebiotic structures. A tholin sample was extracted with chloroform-methanol and the chloroform soluble material was separated by two-dimensional thin layer chromatography. Fluorescence excited by UV light was used to identify the major components on the plates. After being scraped from the TLC plate, the components were eluted as specific fractions and investigated by surface chemical methods, FTIR, scanning electron microscopy and cyclic voltammetry. Fractions 1 and 2 were strongly fluorescent and surface active, producing films at air-water interfaces. When exposed to aqueous phases, components in fraction 1 form spherical microstructures resembling prebionts. The prebionts are precursor structures that might have evolved into the first living cells.

Single-entity electrochemistry mainly focuses on the properties of single nanoscale systems, which provides a new avenue of studying electrochemical processes at the nanoscale rather than in complex ensemble systems. Stochastic collision nanoelectrochemistry (SCNEC), which has emerged as a convenient and fast single-entity electrochemical analysis method, has gone through significant improvements over the past few years. As a powerful tool for the establishment of multiple analytical strategies, SCNEC has broad applications in electrochemical analysis, catalysis, biosensing, and so forth. This technique is especially promising for the rapid analysis of a single entity with respect to size, concentration, aggregation, and kinetic studies. In this Minireview, we summarize the basic principles and experimental techniques of SCNEC and give a brief overview of the cutting-edge developments in SCNEC over the past 3 years.

Electric Literature of 1273-86-5, 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, 1273-86-5, molcular formula is C11H3FeO, belongs to iron-catalyst compound, introducing its new discovery.

Multilayer films made of poly(diallyldimethylammonium) (PDDA), gold nanoparticles (AuNP) of 10 nm diameter and lactate oxidase (LOx), were built for the first time, by layer-by-layer (LBL) assembly technique onto both quartz and gold substrates. The surface plasmon resonance (SPR) band of AuNP was used for monitoring the film growth and adsorption kinetics on PDDA monolayer supported onto quartz substrate. In the case of polycrystalline gold surfaces, electrochemical characterization was performed by means of cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The latter system was used as bioelectrode for L-lactate quantification, showing a short time response (<10 s) with high sensitivity of 63 ± 3 muA mM?1cm?2, detection limit of 0.47 muM and linear range between 0.001 mM and 0.25 mM. This bioelectrode was also tested for L-lactate analysis in yogurt and fermented milk, and it was checked that typical interfering as glucose and citric, acetic and ascorbic acids do not play a role. Present results indicate that self-assembled multilayers made of PDDA/AuNP/LOx are suitable thin films for electroanalytical determination of L-lactate in real samples.

The chemical modification of an sp2 hybridized carbon surface in a controllable manner is very challenging but also crucial for many applications. An inverse electron demand Diels?Alder (IEDDA) reaction using microcontact printing technique is introduced to spatially control the modification of a highly ordered pyrolytic graphite (HOPG) surface under ambient conditions. The covalent modification was characterized by Raman spectroscopy, XPS, and SECM. Tetrazine derivatives can effectively react with an HOPG surface and with microcontact printing methods resulting in spatially patterned surfaces being produced with micrometer-scale resolution.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states.

The different techniques nowadays applied in life sciences may be considered as individual instruments in a symphony orchestra, each providing different valuable information. Fundamental questions are addressed regarding biomolecules, biomolecule-modified surfaces, live cells and complex biological functions such as cell signaling cascades, influences on cell proliferation, gene expression and cell death. Techniques such as optical microscopy, electrophoresis, chromatographic techniques bulk or on-chip electrochemical measurements and spectroscopic techniques are among the approaches providing bulk information usually averaging over a large number of biological entities. However, for most of the listed techniques either modification or complexing agents may be necessary and/or the obtained information cannot be correlated to structural changes. Fluorescence-based and high-resolution optical techniques provide spatially resolved information down to individual molecules (e.g., single molecule fluorescence) but usually require labeling steps.1 Scanning probe microscopy (SPM) techniques such as atomic force microscopy (AFM),2 scanning electrochemical microscopy (SECM)3 and scanning ion conductance microscopy (SICM)4 yield valuable information when investigating biological samples in respect to topographical and structural analysis of, for example, cells, yet some of them lack chemical and molecular specificity. In particular electrochemical methods5,6 play a dominant role in studying signaling processes as many transmitter molecules are either electroactive molecules (e.g., catecholamines)7 or can be selectively determined using biosensors.8 Ideally, the detection of specific constituents and the response to stimulation and/or changes of the biological sample should be obtained in a temporally and spatially resolved manner. SECM, as introduced by Bard and co-workers,9 is an attractive scanning probe technique for life sciences and related research areas, which was already demonstrated by early investigations on biological samples10,11 and first enzyme activityrelated investigations presented in 1992.12 Since then, SECM evolved into an increasingly popular technique for studying biochemical and bio-related processes. Significant progress has been made over the years in instrumental developments, by introducing new imaging modes and establishing comprehensive theoretical models. While the early years of SECM were certainly shaped by the team of A. Bard and the research groups emerging from this nucleus, not much later research groups in Japan13-15 and Europe16-24 contributed to SECM research in the field of life sciences. In the early twenty-first century, SECM was improved in respect to resolution, introducing new imaging modalities and SECM research expanded to the investigation of DNA,25-27 cells,28,29 membranes30,31 and neurons.32 Returning to the metaphor of an orchestra, the musical development in allegro was not just limited to its leitmotif of SECM, but combinations with other scanning probe techniques such as AFM and SICM or optical techniques enriched the Symphony. Within this chapter an overview on SECM is provided along with the imaging modalities on biologically relevant applications in the life sciences and related research areas with selected examples. As this chapter cannot be comprehensive, the interested reader is directed further to the seminal book Scanning Electrochemical Microscopy.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.

We propose an innovative nanoarchitecture for the development of electrochemical biosensors based on the non-covalent functionalization of multi-walled carbon nanotubes (MWCNTs) with the lectin Concanavalin A (ConA) and the site-specific supramolecular binding of glycobiomolecules. As proof-of-concept, we propose the use of two glycoenzymes, glucose oxidase (GOx) and horseradish peroxidase (HRP), for building mono and bienzymatic glucose biosensors. The selected conditions for the preparation of the dispersion were 1.5 mg MWCNTs in 1.0 mL of 2.0 mg mL?1 ConA sonicated for 5.0 min with sonicator probe. The monoenzymatic glucose biosensor was prepared by casting GCE with the MWCNTs-ConA dispersion (GCE/MWCNTs-ConA) followed by the interaction with GOx (GCE/MWCNTs-ConA/GOx), while the bienzymatic one was obtained by interaction of GCE/MWCNTs-ConA with GOx + HRP (GCE/MWCNTs-ConA/GOx-HRP). The best analytical performance was obtained with the bienzymatic biosensor from the amperometric response at -0.050 V in the presence of 1.0 × 10-4 M hydroquinone. The sensitivity was (2.22 ± 0.03) muA mM?1 (which was 5.2 times higher than the one obtained with the monoenzymatic biosensor) and a detection limit of 0.31 muM. The reproducibility was 5.4% and the biosensor was challenged with human blood serum showing an excellent correlation with the values reported by the laboratory.

Electrochemical grafting of a water-insoluble diazonium salt in aqueous media onto an electrode surface was achieved by host-guest complexation. 1-(2-Bisthienyl)-4-aminobenzene (BTAB) was solubilized in a water/beta- cyclodextrin solution (beta-CD). The corresponding diazonium salt was generated in situ then electroreduced. This process leads to the attachment of bithiophene or short oligothiophene groups to the electrode surface. The modified surfaces were analyzed by cyclic voltammetry (CV), scanning electrochemical microscopy (SECM), X-ray photoelectron spectroscopy (XPS), infrared reflection absorption spectroscopy (IRRAS), and atomic force microscopy (AFM). The electrochemical investigations show that the waterbased modified surface is similar to one generated in acetonitrile without beta-CD. Thus, the attached organic layer behaves like an electrochemical switch (above some threshold potential, a soluble external probe is oxidized, but the oxidized form cannot be reduced). The modified surfaces consist of grafted bisthienylbenzene (BTB) and cyclodextrins that can be removed from the surface. This procedure may be considered as a new means of creating a surface made of submicrometric holes in an organic semiconducting layer.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. In my other articles, you can also check out more blogs about 1273-86-5

A series of ruthenium(II) complexes incorporating a thiosemicarbazone chelate tethered with a diphenylphosphine pendant have been studied. Thus, [(PNS-Et)RuCl(CO)(PPh3)] (1), [N,S-(PNS-Et)RuH(CO)(PPh3)2] (2) and [(PNS-Et)RuCl(PPh3)] (3) were synthesized by reactions of various RuII precursors with 2-(2-(diphenylphosphino)benzylidene)-N-ethylthiosemicarbazone (PNS-Et). However, complexation of PNS-Et with an equimolar amount of [RuCl2(dmso)4] resulted in two different entities [(PNS-Et)RuCl(dmso)2] (4) and [(PNS-Et)2Ru] (5) with different structural features in a single reaction. All the RuII complexes have been characterized by analytical and various spectroscopic techniques. Compounds 1-5 were recrystallized, and the X-ray crystal structures have been reported for 1, 2 and 5. In the complexes 1 and 3-5 the ligand coordinated in a tridentate monobasic fashion by forming PNS five- and six-membered rings, whereas in 2, the ligand coordinated in a bidentate monobasic fashion by forming a strained NS four-membered ring. Furthermore, compounds 1-5 showed catalytic activity in N-alkylation of heteroaromatic amines. Notably, complexes 1-3 were found to be very efficient catalysts toward N-alkylation of a wide range of heterocyclic amines with alcohols. In the presence of a catalytic amount of 2 with 50 mol% of KOH, N1,C5-dialkylation of 4-phenylthiazol-2-amine has been investigated. Reaction of in situ generated aldehyde with amine yields the N1,C5-dialkylated products through the hydride ion transformation from alcohol. Complexes 1-3 also catalyzed a variety of coupling reactions of benzyl alcohols and sulfonamides, which were realized often with 99% isolated yields. Advantageously, only one equivalent of the primary alcohol was consumed in the process.

The performances of a single microband electrode probing within a microfluidic channel, the passage of a concentration front of electroactive species,were investigated. Optimal conditions in terms of device geometries and hydrodynamic flow were delineated to allowamperometric detectionswith high temporal resolution. These conditions correspond to specific regimes reflecting the complex coupling between diffusional and convective transport. Experimental current responses were in excellent agreement with the theoretical predictions. A new concept of microchannel electrodes acting as concentration probes was thus successfully demonstrated.
