Optical Behavior of Nile Red in Organic and Aqueous Media Environments
Applied Sciences, 2023 A simple model is proposed to calculate the dimerization constant of a dye in non-aqueous solvents. Alkan-1ols of the formula H–(CH2)n–OH are used to study the spectroscopic behavior of Nile Red dye. The number n varied from 1 to 8 to modulate the medium

Modified model of Newtonian gravitation.
Тонкие химические технологии, 2011 Within the limits of the classical mechanics for planets of the Solar system a new form of gravitational potential is suggested. The following effects are considered: perihelion advance of the planets, deviation of light beams in the field of the Sun ...

An overview on the quasar redshifts
Revista Técnica de la Facultad de Ingeniería, 2011 An overview of the foundations of modem cosmology a well as the controversies about physical association between high-red shift quasi-stellar objects and low-red shift galaxies are presented. This kind of evidence challenges the current velocity-distance

Pink illusions and white shifts
i-PerceptionA rotating stimulus of alternating red and white sectors generates a faint pink fill throughout the image. The trailing cyan after images of the red sectors quickly become the brightest regions in the image, providing an index of the overall illumination

Red Shift in a Laboraory Environment
, 2011 A hypotheses of energy loss for polarization of e-e+ vacuum by a photon passing interstellar space is considered. An excitation and relaxation of vacuum can't run with speed of light due to very small but finite fraction of e-e+ pair mass that creates a retardment in recuperation of deposited energy back to photon.
