Download or read book Physico chemical Characterization of Size selected Internal Combustion Engine Nanoparticles and Original Method for Measuring Adsorption Energies on Carbonaceous Surfaces by Laser Mass Spectrometry written by Dumitru Duca and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emission of carbonaceous aerosols by combustion-powered ground transport vehicles has a major impact on both global climate and human health. Intensive research efforts are dedicated to the development of robust procedures able to reliably measure particles as small as 10 nm in real-driving conditions, as current European Union regulations are limited to 23 nm. Within the H2020 PEMS4Nano project, we performed detailed physico-chemical characterization of size-selected particulate matter emitted by a gasoline direct injection engine. This included chemical characterization performed with mass spectrometry as well as structural/morphology data obtained with electron and atomic force microscopy together with Tip-Enhanced Raman Spectroscopy. In addition, to gain insight into the interaction between the carbonaceous surface and adsorbed compounds, a novel laser-based method for determining the adsorption energy of chemical species on carbonaceous surfaces was developed.

Download or read book Improving Sensitivity and Specificity when Measuring Environmental Exposure to Engineered Nanoparticle Releases with the Use of Low Background Techniques written by Heather Laine Papinchak and published by . This book was released on 2013 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: As applications of nanotechnology expand, there is an increasing need to develop inexpensive, sensitive, and specific procedures to measure occupational exposures to engineered nanoparticles (ENPs). The use of hand-held direct reading instruments to screen for airborne ENPs is attractive due to the relatively low cost of such commercially available instruments and the immediate feedback provided. However, because ambient air typically contains thousands of non-engineered nanoparticles per cubic centimeter (pt/cm3), this background particle concentration must be accounted for in quantifying ENPs. Incidental nanoscale particles are present in many workplaces due to sources including internal combustion engines, grinding and welding, electric motors, office equipment, printers, and infiltration of contaminated outside air. Because ENP toxicity has not been investigated comprehensively, and because some studies suggest that certain ENPs may be highly toxic, the risk management philosophy of many organizations is that exposure to ENPs above background nanoparticle levels is not acceptable. Industrial hygienists have generally approached ENP sampling with the notion that if ENPs cannot be detected above background levels in the sampling environment, exposure to ENPs is not occurring. If there is a low signal-to-noise ratio, however, this approach underestimates ENP exposure intensity, and large fluctuations in background concentrations could make it difficult to measure actual releases of ENPs. Therefore, it is important to accurately discern between background non-engineered nanoparticle and ENP concentrations. The few ENP exposure studies that have been published tend to inadequately account for background nanoparticles. Tools and techniques were developed to improve the sensitivity and specificity of ENP exposure measurements in research laboratories based on direct reading instruments and filter-based sampling. These research facilities were located at the Lawrence Berkeley National Laboratory (LBNL). A portable fume-hood antechamber enclosure and a portable, bottomless glovebox enclosure were constructed. These enclosures are supplied with air passed through a high efficiency particulate air (HEPA) filter air, and ENP-handling tasks are performed within the enclosures. HEPA filtration greatly reduces the nanoparticle concentration in the supply air and thereby increases the ENP signal-to-noise ratio. Based on measurements made with a commercially available CPC, a 100- to 300-fold increase in sensitivity was achieved with the clean air enclosures. Combined with high-resolution microscopy analysis of particles collected on filter samples of air, employee exposures to ENPs that were previously not detectable using traditional sampling techniques were quantified. Three different monitoring studies are described in this dissertation. The first study characterized airborne metal-oxide LiNi0.45Mn0.45Co0.1-yAlyO2 ENP emissions associated with a nanomaterial synthesis comprised of three steps - heating a precursor solution, combustion, and harvesting - all conducted within a laboratory fume hood. With the use of the cleanroom enclosure, background particle concentration levels of 0-2 pt/cm3 were achieved. A CPC was located in the cleanroom enclosure at waist-level or near the personal breathing zone (PBZ) of the LBNL researcher, and a second CPC was located inside the laboratory fume hood. The maximum of 465,129 pt/cm3 (measured inside the fume hood) was the highest particle concentration recorded in this research. For all the combustion events, I observed plumes of black particles which corresponded in time with the highest particle measurements. To my knowledge, there are no published studies that have shown such high particle number concentrations from ENP synthesis. At the conclusion of the synthesis, ENM was found on fume hood surfaces and equipment, and on the CPC instrument located in the fume hood. ANOVA demonstrated that the mean particle number concentrations were not equal across the three steps (p

Download or read book Laser Diagnostics and Optical Measurement Techniques in Internal Combustion Engines written by Hua Zhao and published by SAE International. This book was released on 2012-07-30 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing concern about CO2 emissions and energy prices has led to new CO2 emission and fuel economy legislation being introduced in world regions served by the automotive industry. In response, automotive manufacturers and Tier-1 suppliers are developing a new generation of internal combustion (IC) engines with ultra-low emissions and high fuel efficiency. To further this development, a better understanding is needed of the combustion and pollutant formation processes in IC engines. As efficiency and emission abatement processes have reached points of diminishing returns, there is more of a need to make measurements inside the combustion chamber, where the combustion and pollutant formation processes take place. However, there is currently no good overview of how to make these measurements. Based on the author’s previous SAE book, Engine Combustion Instrumentation and Diagnostics, this book focuses on laser-based optical techniques for combustion flows and in-cylinder measurements. Included are new chapters on optical engines and optical equipment, case studies, and an updated description of each technique. The purpose of this book is to provide, in one publication, an introduction to experimental techniques that are best suited for in-cylinder engine combustion measurements. It provides sufficient details for readers to set up and apply these techniques to IC engines and combustion flows.

Download or read book Nanoparticles in medicine and environment written by J.C. Marijnissen and published by Springer Science & Business Media. This book was released on 2009-12-01 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: A huge effort is put into the science of nanoparticles and their production. In many cases it is unavoidable that nanoparticles are released into the environment, either during the production processes or during the use of a product made from these particles. It is also realized that combustion processes like traffic and power plants release nanoparticles into the atmosphere. However it is not known how nanoparticles interact with the human body, especially upon inhalation. At the same time research activities are devoted to understand how nano-sized medicine particles can be used to administer medicines via inhalation. In any case it is absolutely necessary to know how the nanoparticles interfere with the inhalation system, how they deposit and affect on the human system. Three main themes are discussed: Nanoparticle sources and production Nanoparticle inhalation and deposition Toxicological and medical consequences of nanoparticles Each theme is covered comprehensively, starting at nano-quantum effects up to technical and medical applications such as measuring equipment and inhalation instrumentation. This book brings together all sub-disciplines in the field related to aerosol nanoparticles. Each chapter is written by a world expert, giving the state of the art information and challenging open questions. The last chapter summarizes in an interdisciplinary way what is already known and what still is ahead of us.
