Book Description
The University of Wyoming’s Department of Atmospheric Science received funding through the National Science Foundation for the next generation King Air (UWKA-2) that will include a selection of current and new instruments. Part of this suite of instrumentation includes the new Single Particle Soot Photometer - Extended Range (SP2-XR) that can not only measure scattering particles but also refractory black carbon (BC) mass. As the Intergovernmental Panel on Climate Change (IPCC)’s annual climate report continues to show a large uncertainty in the effective radiative forcing of BC, the instrument was ordered to supplement the aging and scattering-only Ultra High Sensitivity Aerosol Spectrometer (UHSAS), to be able to collect BC incandescence measurements. The SP2-XR and UHSAS were flown together in the Deployable Instruments - Laramie Based - Research Test Flights - 2021 (Project Dilbert 21) as well as calibrated to verify instrument stability over time. The SP2-XR was found to have stable diameter measurements over a period of 30 months to within 20 % of the factory calibrations for both scattering and incandescence. The flight performance between the SP2-XR and UHSAS shows good agreement at higher altitudes and some divergence at lower altitudes. By plotting size distributions and combining bins of the UHSAS to match the SP2-XR, these differences were quantified to be as much as 29 % in the number distribution to 49 % in the volume distribution. Dividing the flight data and calibration data into bins shows that more calibration testing needs to be done to reconcile smaller bin sizes and larger bin sizes as this is where agreement diverges between the two instruments and calibrations.

Book Description
This book systematically examines and quantifies industrial problems by assessing the complexity and safety of large systems. It includes chapters on system performance management, software reliability assessment, testing, quality management, analysis using soft computing techniques, management analytics, and business analytics, with a clear focus on exploring real-world business issues. Through contributions from researchers working in the area of performance, management, and business analytics, it explores the development of new methods and approaches to improve business by gaining knowledge from bulk data. With system performance analytics, companies are now able to drive performance and provide actionable insights for each level and for every role using key indicators, generate mobile-enabled scorecards, time series-based analysis using charts, and dashboards. In the current dynamic environment, a viable tool known as multi-criteria decision analysis (MCDA) is increasingly being adopted to deal with complex business decisions. MCDA is an important decision support tool for analyzing goals and providing optimal solutions and alternatives. It comprises several distinct techniques, which are implemented by specialized decision-making packages. This book addresses a number of important MCDA methods, such as DEMATEL, TOPSIS, AHP, MAUT, and Intuitionistic Fuzzy MCDM, which make it possible to derive maximum utility in the area of analytics. As such, it is a valuable resource for researchers and academicians, as well as practitioners and business experts.

Book Description
The book provides a comprehensive record of current knowledge on the nature of Fusarium head blight, the damage it causes, and current research on how to control it. The book begins with a historical account of Fusarium head blight epidemics that gives context to recent attempts to control epidemics in wheat and barley. A review of pathogen taxonomy and population biology helps scientists to see relationships among head blight pathogens and other Fusarium species. The information on epidemiology included in this review also provides an understanding of the weather conditions and cultural practices that promote explosive epidemics. New information on infection processes will lead the reader to a better understanding of how to breed for resistance in wheat and barley.

Book Description
The book explains the principles and fundamentals of photocatalysis and highlights the current developments and future potential of the green-chemistry-oriented applications of various inorganic, organic, and hybrid photocatalysts. The book consists of eleven chapters, including the principles and fundamentals of heterogeneous photocatalysis; the mechanisms and dynamics of surface photocatalysis; research on TiO2-based composites with unique nanostructures; the latest developments and advances in exploiting photocatalyst alternatives to TiO2; and photocatalytic materials for applications other than the traditional degradation of pollutants, such as carbon dioxide reduction, water oxidation, a complete spectrum of selective organic transformations and water splitting by photocatalytic reduction. In addition, heterogeneized polyoxometalate materials for photocatalytic purposes and the proper design of photocatalytic reactors and modeling of light are also discussed. This book appeals to a wide readership of the academic and industrial researchers and it can also be used in the classroom for undergraduate and graduate students focusing on heterogeneous photocatalysis, sustainable chemistry, energy conversion and storage, nanotechnology, chemical engineering, environmental protection, optoelectronics, sensors, and surface and interface science. Juan Carlos Colmenares is a Professor at the Institute of Physical Chemistry, Polish Academy of Sciences, Poland. Yi-Jun Xu is a Professor at the State Key Laboratory of Photocatalysis on Energy and Environment, College of Chemistry, Fuzhou University, China.

Book Description
All living things contain carbon in some form, as it is the primary component of macromolecules including proteins, lipids, nucleic acids (RNA and DNA), and carbohydrates. As a matter of fact, it is the backbone of all organic (chemistry) compounds forming different kinds of bonds. Carbon: The Black, the Gray and the Transparent is not a complete scientific history of the material, but a book that describes key discoveries about this old faithful element while encouraging broader perspectives and approaches to its research due to its vast applications. All allotropes of carbon are described in this book, along with their properties, uses, and methods of procurement or manufacturing. Black carbon is represented by coal, gray carbon is represented by graphite, and transparent carbon is represented by diamond.

Book Description
Fullerenes and nanotubes are two classes of carbon structures or allotropes, which were discovered about 17 years ago. Since that time, many chemical derivatives have been synthesized using fullerenes and nanotubes as building blocks. Particularly promising was the theory that the chemical properties of fullerenes, and certain derivatives, made them likely candidates for anticancer drugs, inhibitors of viruses such as HIV, or even as anti-bacterials. Their cyctotoxicity can also be controlled by specific circumstances. In addition, the funtionalization of nanotubes has not only produced relatively simple derivatives, but also complex hybrids with biological macromolecules, which show unique supramolecular architecture and which are promising in many medical applications. The application of fullerenes and nanotubes in medicine is at the frontier of our knowledge, thus the work in this field represents the basis for future novel developments.
