Available in PDF, EPUB and Kindle. Book excerpt: Gas molecules such as O2, NO, CO and ethylene are present in the environment and are endogenously (enzymatically) produced to act as signalling molecules in biological systems, including the regulation of metabolic networks, chemotaxis, circadian rhythms, mammalian hypoxia responses, and plant ethylene responses by transcriptional, translational, or post translational control. Sensing these gas molecules is the first step in their acting as signalling molecules. When a sensor domain/protein senses an external signal, intra- and inter-molecular signal transductions take place to regulate the biological function of a regulatory domain/protein such as DNA-binding, enzymatic activity, or protein–protein interaction. Interaction between gas molecules and sensor proteins is essential for recognition of gas molecules. Metal-containing prosthetic groups such as haem, iron–sulfur clusters, and non-haem iron centres are widely used. As these metal-containing centres are good spectroscopic probes, detail characterizations have utilized spectroscopic techniques along with X-ray crystallography. Covering both the signalling and sensing of gaseous molecules, this book provides the first comprehensive overview of gas sensor proteins in both prokaryotic and eukaryotic cells. This book will be particularly interesting to postgraduates and researchers in biochemistry, molecular biology and metallobiology.

Download or read book Advanced Gas Sensing written by Theodor Doll and published by Springer Science & Business Media. This book was released on 2003-05-31 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced Gas Sensing focuses on the Electroadsorptive Effect: its theory, experimental measurement and applications in consumer gas sensors as well as in surface physics laboratory work. The Electroadsorptive Effect is invaluable when used in MEMS gas sensors. The authors use a general approach that covers new insights into temperature modulation and the use of light. The emphasis is given to electrical fields in gas sensors, which cause the Electroadsorptive Effect. The effect has long been known by experts working in the field, but has been regarded as too difficult for use until recently because of increasing sensor miniaturization. The book will serve as an introduction to sensitivity tuning of semiconductor gas sensors, introducing the underlying theory and experimental models before moving on to design considerations, applications and market considerations. A literature review and examples of experimental data are included.

Download or read book Gas Sensors written by G. Sberveglieri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: There were two reasons that induced me to plan and to organize this book, the first was the lack of a text entirely devoted to the subject of gas sensors, notwithstanding some books devoted to the various kind of chemical sensors have recently been published. The second reason was the need of introducing the basic topics of gas detection mechanisms to a growing number of researchers active in research and development laboratories of industries and uni versities. The field of chemical sensors is indeed in fast and consistent growth, as it is proved by the increased number of participants to the congresses that were recently held on this subject, namely the Third Meeting on Chemical Sensors (September 24 - 26, 1990, Cleveland), Transducers' 91 (June 24 - 27, 1991, S. Francisco) and EUROSENSORS V (September 30 - October 3, 1991, Rome). Therefore, this book is mainly intended as a reference text for researchers with a MS degree in physics, chemistry and electrical engineering; it reports the last progresses in the R. & D. and in the technology of gas sensors. I choose to deal specifically with the topic of gas sensors because these devices show a very large number of applications in the domestic and industrial field and they are characterized by a great effort of research and development.

Download or read book Higher order Sensors for Fast Detection of Gases written by Isao Sasaki and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The research is divided into two main parts: the sensing part and the gas delivery part. The reliable chemical information from the chemical sensor requires that the sensitive layer of the sensor exhibits long-term stability. To improve the stability of the sensing layer, camphorsulfonic acid was added to the formic acid. The introduction of photo-irradiation at 254 nm as an additional treatment to the sensing layer was proved to be effective. For gas selectivity of PANI matrix, metal or metal oxide clusters have been incorporated into the matrix. The composite materials of PANI with silver, copper, iron, nickel, palladium and mercury were also prepared and exposed to different gases. The second part of the thesis discusses the gas delivery system to the sensors using the synthetic jet technology. The sniffing functionality was demonstrated using the designed jet cell for operation in the open system. The gas sniffing experiments showed that in the presence of the jet, the response time of the sensor is faster by about two orders of magnitude (20 compared to 1800 seconds). The jet sampling system was applied to continuous monitoring of ammonia gas filter performance using the chemFET array. The jet system collected the gas before and after filtering, and the difference between the two responses was compared to observe the break-through of the filter. It was concluded that the gas sensing system integrated with the gas sampling functionality can be applied to monitor a gas filter performance. The cell was designed so that the impinging jet covers the sensing active area of the array of eight chemFETs. The two-dimensional distribution of the ammonia gas concentrations showed that the jet covers the active sensing area in an effective way so that the sampling volume for sensing is significantly reduced compared with the conventional gas flow cell system. Based on these initial studies shown in this thesis, the proposed gas sniffing system was shown to be effective in realizing fast detections of gases for critical applications of a gas sensor system.

This book was released on 2008-11-25 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Study Institute on “Sensors for Environment, Health and Security: Advanced Materials and Technology” was held in Vichy (France) on September 16–27, 2007 where more than 65 participants, ranging from Ph. D. students to experienced senior scientists, met and exchanged ideas and know-how in a friendly atmosphere. The present book intends to cover the main topics of this NATO ASI through 32 chapters distributed over two parts (Part I: “Materials and Technologies” and Part II: “Applications to Environment, Health and Security”). The scientific programme of the NATO ASI consisted in 28 1-hour lectures given by 14 invited lecturers, 5 additional 1-hour lectures given by seminar speakers, 22 oral presentations by selected ASI participants and a poster session. The programme was divided into four sessions: (1) Advanced materials and technologies; (2) Sensors for environment; (3) Sensors for health; (4) Sensors for security. During the “Advanced Materials and Technologies” session (Part I of the present book), the lectures were dedicated to critical analyses of current methods for the synthesis of materials, nanomaterials (nanoparticles, nanowires, nanotubes, ...) and nanocomposites to be used for the fabrication of sensing devices, mainly semiconductor sensors. Among the synthesis methods, chemical (sol-gel, etc. ) and physical methods (laser deposition, DC magnetron sputtering, etc. ) were discussed. Several lectures addressed characterization techniques and it was concluded that the physical and chemical control of the materials/nanomaterials, including surface chemistry, remains a key issue for the reproducibility of the final device.
