The Physics and Physical Chemistry of Molecular Machines [PDF]

open access: yesChemPhysChem, 2016
AbstractThe concept of a “power stroke”—a free‐energy releasing conformational change—appears in almost every textbook that deals with the molecular details of muscle, the flagellar rotor, and many other biomolecular machines. Here, it is shown by using the constraints of microscopic reversibility that the power stroke model is incorrect as an ...

The Parametric Generalized Fractional Nikiforov-Uvarov Method and Its Applications

open access: yesEast European Journal of Physics, 2023
By using generalized fractional derivative, the parametric generalized fractional Nikiforov-Uvarov (NU) method is introduced. The second-order parametric generalized differential equation is exactly solved in the fractional form. The obtained results are

Strong enhancement of double Auger decay following plasmon excitation in C60 / Усиление двойного Оже-распада, сопровождающего возбуждение плазмонов в С60 / Jako pojačanje dvostrukog ožeovog raspada koji prati plazmonsku ekscitaciju u C60 [PDF]

open access: yesVojnotehnički Glasnik, 2018
One of the important characteristics of the C60 molecule is the collective response of its valence electron cloud to the electromagnetic radiation. This collective behavior gives rise to the occurrence of the giant dipole resonance (so called surface ...

Numerical Simulation of The Spectroscopic Properties of The Laser Dye for Low Concentrations

open access: yesAl-Mustansiriyah Journal of Science, 2022
In the current study, a mathematical model using the MATLAB program was studied depending on the logistic power peak function to simulate the change in the absorbance with the different values of the concentrations of Rhodamine B.

Strong-field physics in the molecular frame [PDF]

open access: yesEPJ Web of Conferences, 2019
Laser-aligned carbonyl-sulfide molecules were strong-field ionized using mid-infrared light. Investigating the strong-field effects in the molecular frame allowed to add novel facets to the understanding of the intrinsic nature of strong-field physics.
