Book Synopsis Arsenic in Drinking Water by : National Research Council
Download or read book Arsenic in Drinking Water written by National Research Council and published by National Academies Press. This book was released on 2001-11-26 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.

Book Synopsis Functionalized epitaxial graphene as versatile platform for air quality sensors by : Marius Rodner
Download or read book Functionalized epitaxial graphene as versatile platform for air quality sensors written by Marius Rodner and published by Linköping University Electronic Press. This book was released on 2021-04-12 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this thesis focuses on epitaxial graphene on SiC as a platform for air quality sensors. Several approaches have been tested and evaluated to increase the sensitivity, selectivity, speed of response and stability of the sensors. The graphene surfaces have been functionalized, for example, with different metal oxide nanoparticles and nanolayers using hollow-cathode sputtering and pulsed laser deposition. The modified surfaces were investigated towards topography, integrity and chemical composition with characterization methods such as atomic force microscopy and Raman spectroscopy. Interaction energies between several analytes and nanoparticle-graphene-combinations were calculated by density functional theory to find the optimal material for specific target gases, and to verify the usefulness of this approach. The impact of environmental influences such as operating temperature, relative humidity and UV irradiation on sensing properties was investigated as well. To further enhance sensor performances, the first-order time-derivative of the sensor’s resistance was introduced to speed up sensor response and a temperature cycled operation mode was investigated towards selectivity. Applying these methods in laboratory conditions, sensors with a quantitative readout of single ppb benzene and formaldehyde were developed. These results show promise to fill the existing gap of low-cost but highly sensitive and fast gas sensors for air quality monitoring. Der Fokus dieser Thesis liegt auf der Erforschung von epitaxialem Graphen auf SiC als Plattform für Luftgütesensoren. Diverse Ansätze wurden untersucht, um die Sensitivität, Selektivität, Reaktionsgeschwindigkeit und Stabilität der Sensoren zu verbessern. Die Graphenoberfläche wurde unter anderem mit Metalloxid-Nanopartikeln oder nanometerdünnen Schichten funktionalisiert. Die funktionalisierten Sensorschichten wurden hinsichtlich ihrer Oberflächenbeschaffenheit, Unversehrtheit und chemischen Zusammensetzung mittels Rasterkraftmikroskopie und Raman Spektroskopie untersucht. Die Reaktionsenergien zwischen verschiedenen Analyten und Nanopartikel-Graphen-Kombinationen wurden mit Dichtefunktionaltheorie berechnet, um das optimale Material für spezifische Gase zu finden und um die Brauchbarkeit dieser Funktionalisierungsmethode zu verifizieren. Der Einfluss von äußeren Parametern wie Sensortemperatur, Luftfeuchte und UV-Einstrahlung auf die Sensoreigenschaften wurde ebenfalls untersucht. Um die Sensorleistung zu verbessern, wurde die erste zeitliche Ableitung des Sensorwiderstands als zusätzliches Signal eingeführt und ein temperaturzyklischer Betriebsmodus hinsichtlich seiner Eignung erforscht. Durch die Anwendung dieser Methoden ist es möglich, einzelne ppbs Benzol und Formaldehyd unter Laborbedingungen zu detektieren. Diese Ergebnisse sind vielversprechend, um die bestehende Lücke der günstigen, aber sehr sensitiven Sensoren für Luftqualitätsüberwachung zu schließen. Arbetet som presenteras i denna avhandling fokuserar på epitaxiell grafen på SiC som en plattform för luftkvalitetssensorer. Flera tillvägagångssätt har testats och utvärderats för att öka känsligheten, selektiviteten, responstiden, och stabiliteten hos sensorerna. Grafenytorna har modifierats till exempel med olika metalloxid-nanopartiklar och nanolager med användning av hålkatodsputtring och PLD. De modifierade ytorna undersöktes mot topografi, strukturell integritet och kemisk sammansättning med karakteriseringsmetoder som atomkraftsmikroskopi och Ramanspektroskopi. Interaktionsenergier mellan flera analyter och nanopartiklar-grafen- materialkombinationer beräknades med täthetsfunktionalteori för att hitta de optimala materialkombinationerna för specifika målgaser och för att verifiera användbarheten av ytmodifieringarna. Effekten av externa faktorer som arbetstemperatur, relativ fuktighet och UV-bestrålning på avkänningsegenskaper undersöktes också. För att ytterligare förbättra sensorprestanda introducerades första ordningens tidsderivat av sensorns resistans för att snabbare utvärdera sensorns respons, och ett temperaturcyklat driftläge i kombination med multivariat dataanalys undersöktes mot selektivitet. Genom att använda dessa metoder under laboratorieförhållanden utvecklades sensorer med en kvantitativ avläsning av enstaka ppb bensen och formaldehyd. Dessa resultat visar på en möjlig lösning för att fylla det hålrum som finns i dagens sensorteknologier för luftkvalitetsövervakning, där flera relevanta gaser i dagsläget inte kan mätas med kostnadseffektiva men mycket känsliga och snabba gassensorer.

Book Synopsis Flexoelectricity in Liquid Crystals by : Agnes Buka
Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

Download or read book Yield Design written by Jean Salençon and published by Wiley-ISTE. This book was released on 2013-05-20 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the middle of the 20th Century yield design approaches have been identified with the lower and upper bound theorem of limit analysis theory – a theory associated with perfect plasticity. This theory is very restrictive regarding the applicability of yield design approaches, which have been used for centuries for the stability of civil engineering structures. This book presents a theory of yield design within the original “equilibrium/resistance” framework rather than referring to the theories of plasticity or limit analysis; expressing the compatibility between the equilibrium of the considered structure and the resistance of its constituent material through simple mathematical arguments of duality and convex analysis results in a general formulation, which encompasses the many aspects of its implementation to various stability analysis problems. After a historic outline and an introductory example, the general theory is developed for the three-dimensional continuum model in a versatile form based upon simple arguments from the mathematical theory of convexity. It is then straightforwardly transposed to the one-dimensional curvilinear continuum, for the yield design analysis of beams, and the two-dimensional continuum model of plates and thin slabs subjected to bending. Field and laboratory observations of the collapse of mechanical systems are presented along with the defining concept of the multi-parameter loading mode. The compatibility of equilibrium and resistance is first expressed in its primal form, on the basis of the equilibrium equations and the strength domain of the material defined by a convex strength criterion along with the dual approach in the field of potentially safe loads, as is the highlighting of the role implicitly played by the theory of yield design as the fundamental basis of the implementation of the ultimate limit state design (ULSD) philosophy with the explicit introduction of resistance parameters.
