Download or read book Electrochemistry in Research and Development written by R. Kalvoda and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers presented at the UNESCO Scientific Forum on Chemistry in the Service of Mankind - Electrochemistry in Research and Development, held in Paris, June 4-6, 1984. Electrochemistry is concerned with the way electricity produces chemical changes and in turn chemical changes result in the production of electricity. This interaction forms the basis for an enormous variety of processes ranging from heavy industry through batteries to biological phenomena. Although there are many established applications, modern research has led to a great expansion in the possibilities for using electrochemistry in exciting future developments. To encourage this progress, UNESCO has set up an Expert Committee on Electrochemistry and its Applications in the European and North American region, which has already held a number of meetings devoted to specific topics. To achieve a synthesis of the main directions of development and to demonstrate the importance of these for the needs of our modern society, the Expert Committee organized a Forum on Electrochemistry in Research and Development. The object of this was to assess the future trends in research and development and to establish a dialogue between experts in electrochemistry and their colleagues in the many other disciplines which can make use of electrochemistry. The Forum was also intended to present electrochemistry and its applications in a form accessible to non-specialists so that science policy-makers will be aware of the potentialities of this subject for the future needs of mankind.

Download or read book Electrochemical Sensing for Food Quality and Safety written by and published by . This book was released on 2013 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: An electrochemical sensor is a self-contained integrated device capable of generating specific quantitative or semi-quantitative analytical signals based on a biological or chemical recognition element/receptor in combination with an electrochemical transduction element. Electrochemical analytical sensors are used a wide range of industries such as pharmaceutical, healthcare, food, agriculture, environment and water. Food and drink industries are in need for reliable detection technologies to assure product quality, monitor deleterious ingredients and contaminants and process control. Electrochemical sensors afford such promising applications in food processing and quality control owing to their simplicity, rapidity, affordability and miniaturization for on-site detection. Carbon, as an array of atoms in certain structural forms, exists as diamond, graphite, graphene, fullerenes, carbon nanotubes and amorphous carbon (soft, hard, diamond-like or graphitic carbon) with a number of appealing properties for different purposes. This group of materials is being used in the construction of biosensors as transducers, immobilization matrices, stabilizers, and mediators. In this thesis, different carbon or carbon hybrid based electrochemical biosensors are developed for detection of food ingredients and additives such as sugars. Sugars are not only extensively involved in the production of thousands of food products from cured meat through preserves and frozen fruits to confections, but also directly related to human health such as obesity, glycemic index, metabolism and diseases. The most known health problem is diabetes which is associated with elevated glucose (Glc) level in blood and sometimes in urine and it is yet completely cured as a chronic disease. Several enzyme-free electrochemical sensors were developed for detection of Glc based on different carbon hybrid nanocomposite materials. Vertically well-aligned multi-walled carbonnanotubes (MWCNTs) were firstly synthesized by chemical vapor deposition (CVD) on a tantalum (Ta) foil substrate using a thin layer of magnetron-sputtered cobalt (Co) as catalyst. The as-synthesized MWCNTs were then modified with copper nanoparticles or cobalt oxide/hydroxide nanoparticles. The modified nanocomposites exhibit much higher electrocatalytic activity towards Glc than before modification, with a high sensitivity, fast response time, wide linear range, low detection limit (at signal/noise ratio=3) and long-term stability for weeks. In another work, a facile one-step approach is used to directly deposit chitosan-reduced graphene oxide-nickel nanoparticle (CS-ERGO-NiNPs) composites onto a screen-printed carbon electrode (SPE) with outstanding analytical performances. A microfluidic electrochemical device with polydimethylsiloxane(PDMS) chambers and acrylonitrile butadiene styrene (ABS) plastic holders was fabricated to feature the as-synthesized SPE sensor. Enzymatic electrochemical biosensors were also developed. The first sensor was based on electrochemically-reduced graphene oxide (ERGO) modified with heterogeneous bimetallic gold-palladium (AuPd) nanoparticles, and the as-synthesized material showed extraordinary sensitivity and stability towards oxygen reduction. A biosensor was then constructed by immobilizing glucose oxidase (GOx) as a model enzyme on the nanocomposites for glucose detection through oxygen consumption during the enzymatic reaction and thus this type of sensor is basically suitable for any oxidase-based biosensing. The second enzymatic sensor was fabricated based on platinum nanoparticles (PtNPs)-modified SPE and enzyme-immobilized cellulose paper and the detection was achieved by detection of the hydrogen peroxide (H2O2) generated in the enzymatic reaction which is different from the first sensor. The enzyme-modified paper showed better mechanical properties and the paper fluidic device has many advantages in sensing such as reagent storage, sample delivery, concentration and low cost. Moreover, a disposable indium tin oxide-coated glass (ITO) working electrode was modified by gold nanoparticles (AuNPs)-ERGO for quick detection of lean meat powder compounds in meat samples at low cost for clinical diagnostic and therapeutic purposes as well as to prevent possible illegal use in animal feed. The neurotransmitter dopamine (4-(2-aminoethyl)benzene-1,2-diol) (DA) can be detected using the one-time-use electrode by either amperometry or differential pulse voltammetry (DPV). The electrochemical catalysis of DA was proven to be a surface process and correlates well with the conventional UV-vis spectrophotometric approach but with more than thrice the dynamic range. The sensor also exhibited good stability and capability to detect DA in beef samples, and thus is a promising candidate for simple and inexpensive sub-nanomolar detection of DA, especially in the presence of UV-absorbing compounds. Lastly, a novel and facile approach was developed to synthesize thin films of magnetite (Fe3O4) with epitaxial needle-like columnar grains on titanium nitride (TiN) buffered substrate using DC magnetron reactive sputtering. The electrocatalytic activity of the epitaxial peroxidase-mimetic Fe3O4 thin-film sensor against H2O2 reduction was rapid with a response time less than 5 s. The sensor also exhibited an acceptable stability, a satisfactory sensitivity, good selectivity to the substrate, a dynamic working range and a low detection limit. The sensor performance correlated well (R2= 0.996) with results obtained using a commercial HPLC-UV device. The sensor performance was robust and accurate in measuring H2O2 in some complex food matrices. The advantages of relative simplicity and ease of mass production make the epitaxial Fe3O4 thin film promising candidate for use in sensing applications.

Available in PDF, EPUB and Kindle. Book excerpt: This sixth volume in the book series Progress in HPLC-HPCE examines the enhancement of high- performance liquid chromatography through the development of an advanced mode of electrochemical detection (ECD) --- the coulometric array detection --- from its initial, yet problematic, amperometric (thin-layer) design to the highly sensitive, selective and stable coulometric (flow-through) design. Unlike amperometric electrodes, the coulometric electrode is 100% efficient and measures signals from all of the analyte passing through it, which leads to improved sensitivity as well as unique selectivity. The coulometric electrode array offers the resolution of the photodiode array with the extreme sensitivity of an electrochemical detector.

This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
