Book Description
The general aviation industry is about to be transformed by a rare convergence of technologies, mainly electrification, automation, and autonomy. Small aircraft of the future will be more sustainable, safer to operate, and more capable than today’s piston-engine aircraft. This report describes some of the challenges and opportunities that will arise when the upcoming technology convergence wave finds applications in four- to six-seat aircraft that will enter into service before the end of the 2020s. NOTE: SAE EDGE™ Research Reports are intended to identify and illuminate key issues in emerging, but still unsettled, technologies of interest to the mobility industry. The goal of SAE EDGE™ Research Reports is to stimulate discussion and work in the hope of promoting and speeding resolution of identified issues. These reports are not intended to resolve the challenges they identify or close any topic to further scrutiny. https://doi.org/10.4271/EPR2022015

Book Description
Drop-in replacement biofuels and electrofuels can provide net-zero CO2 emissions with dramatic reductions in contrail formation. Biofuels must transition to second-generation cellulosic feedstocks while improving land and soil management. Electrofuels, or "e-fuels,” require aggressive cost reduction in hydrogen production, carbon capture, and fuel synthesis. Hydrogen has great potential for energy efficiency, cost reduction, and emissions reduction; however, its low density (even in liquid form) combined with it’s extremely low boiling temperature mean that bulky spherical tanks will consume considerable fuselage volume. Still, emerging direct-kerosene fuel cells may ultimately provide a superior zero-emission, energy-dense solution. Decarbonized Power Options for Civil Aviation discusses the current challenges with these power options and explores the economic incentives and levers vital to decarbonization. Until common and enforceable global carbon pricing arrives, targeted national measures (e.g., mandates, price support, and finance) will be required.

Book Description
The primary human activities that release carbon dioxide (CO2) into the atmosphere are the combustion of fossil fuels (coal, natural gas, and oil) to generate electricity, the provision of energy for transportation, and as a consequence of some industrial processes. Although aviation CO2 emissions only make up approximately 2.0 to 2.5 percent of total global annual CO2 emissions, research to reduce CO2 emissions is urgent because (1) such reductions may be legislated even as commercial air travel grows, (2) because it takes new technology a long time to propagate into and through the aviation fleet, and (3) because of the ongoing impact of global CO2 emissions. Commercial Aircraft Propulsion and Energy Systems Research develops a national research agenda for reducing CO2 emissions from commercial aviation. This report focuses on propulsion and energy technologies for reducing carbon emissions from large, commercial aircraftâ€" single-aisle and twin-aisle aircraft that carry 100 or more passengersâ€"because such aircraft account for more than 90 percent of global emissions from commercial aircraft. Moreover, while smaller aircraft also emit CO2, they make only a minor contribution to global emissions, and many technologies that reduce CO2 emissions for large aircraft also apply to smaller aircraft. As commercial aviation continues to grow in terms of revenue-passenger miles and cargo ton miles, CO2 emissions are expected to increase. To reduce the contribution of aviation to climate change, it is essential to improve the effectiveness of ongoing efforts to reduce emissions and initiate research into new approaches.

Book Description
The COVID-19 pandemic has offered the world and its governments many challenges in how they will conduct their responsibilities and best assist their citizens. The COVID-19 pandemic not only brought a global health emergency, but also helped to shed light on systemic inequalities, caused conspiracy and distrust within the masses, and exhausted global health services. The government and nonprofit sector, including healthcare, education, and social service organizations, will have to utilize the best practices, greater collaboration, and joint venturing to survive post pandemic. The Handbook of Research on Transforming Government, Nonprofits, and Healthcare in a Post-Pandemic Era serves as a resource for those in education, healthcare, government, social service, and other nonprofit organizations who wish to advance their missions in an age of uncertainty. It further discusses how democracy can continue to advance the world, its countries, and the way that we see one another. Covering topics such as BIPOC academic leaders, economic development, and health science education, this premier reference source is an essential resource for government officials, public administration, community leaders, advocacy networks, social service organizations, hospital administrators, health officials, medical professionals, students and faculty of higher education, researchers, and academicians.
