Rule 10b-5: The Rejection of the Birnbaum Doctrine by Eason v. General Motors Acceptance Corp. and the Need for a New Limitation on Damages [PDF]

open access: yes, 1974
Det är viktigt att vägarna håller så länge som möjligt. En faktor som har en påverkan i asfaltens långvarighet är bitumen. När bitumenet föråldras försämras dess egenskaper som ökar risken att skador uppstår på asfalten. Med hjälp av olika tillsatser kan

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Research Status and Development Trend of Macromolecular Structure and Model Construction of Different Coals

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Coal is a natural macromolecular substance composed of complex organic molecules and a small amount of minerals. Its chemical composition and microstructure are highly complex and variable, and no unified definition exists. This inherent structural complexity underscores the theoretical significance of constructing accurate macromolecular ...

Homologous Bio‐Tar and Bio‐Tar Pitch as Co‐Carbonization Agents in the Preparation of Mesophase Pitch

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The present work systematically compares the performance differences between two novel homologous materials employed as co‐carbonization agents in the synthesis of mesophase pitch. Low‐cost FCC slurry was used as the raw material, with bio‐tar (BT) and bio‐tar pitch (BTP) as co‐carbonization agents.
