Computational techniques have significantly advanced our understanding of cardiac electrophysiology, yet they predominantly concentrated on averaged models that do not represent the intricate dynamics near individual cardiomyocytes. Recently, accurate representing cells gained popularity, enabling analysis electrophysiology at micrometer level. Here, we evaluate five mathematical to determine their computational efficiency and physiological fidelity. Our findings reveal cell-based introduced...
The Norrish/Yang type II photochemistry of 16 ketones having the basic cis-4-tert-butyl-1-benzoylcyclohexane or 2-benzoyladamantane structure has been investigated in solid state and solution. In both media, bearing methyl substituents α to benzoyl group undergo stereoselective Yang photocyclization afford endo-arylcyclobutanols. Quantum yield quenching studies solution show that reactions are efficient triplet-mediated processes. Asymmetric induction were carried out by providing reactants...
In the title compound extended sheets of cobalt(II) ions, linked in a square array by bridging formates, couple antiferromagnetically. Spin canting generates residual spin on sheets, and interaction between leads to long-range ferromagnetic ordering spontaneous magnetization below 9 K.
