Implementation of the Semi Empirical Kinetic Soot Model Within Chemistry Tabulation Framework for Efficient Emissions Predictions in Diesel Engines [PDF]

open access: yesOpen Physics, 2019
Soot prediction for diesel engines is a very important aspect of internal combustion engine emissions research, especially nowadays with very strict emission norms. Computational Fluid Dynamics (CFD) is often used in this research and optimisation of CFD

Fractional paradigms in quantum chemistry [PDF]

open access: yesInternational Journal of Quantum Chemistry, 2021
AbstractThe realization of fractional quantum chemistry is presented. Adopting the integro‐differential operators of the calculus of arbitrary‐order, we develop a general framework for the description of quantum nonlocal effects in the complex electronic environments.

Fraction B From Catfish Epidermal Secretions Kills Pancreatic Cancer Cells, Inhibits CD44 Expression and Stemness, and Alters Cancer Cell Metabolism

open access: yesFrontiers in Pharmacology, 2021
Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer related death in western countries. The successful treatment of PDAC remains limited. We investigated the effect of Fraction B, which is a fraction purified from catfish (Arius

Fractional Quantum Chemistry [PDF]

open access: yes, 2021
The realization of fractional quantum chemistry is presented. Adopting the integro-differential operators of the calculus of arbitrary-order, we develop a general framework for the description of quantum nonlocal effects in the complex electronic environments. After a brief overview of the historical and fundamental aspects of the calculus of arbitrary-
