Luminescence enhancement of a self-organised Y2O3:Eu3+ thin film-coated porous alumina membrane

Y2O3:Eu3+ thin films were deposited by pulsed laser deposition (PLD) on unordered porous alumina membranes (PAMs). We showed that by adjusting the deposition parameters, self-organisation of Y2O3:Eu3+ on the PAM occurs, which leads to the fo...

Emission of mitochondrial biophotons and their effect on electrical activity of membrane via microtubules

In this paper we argue that, in addition to electrical and chemical signals propagating in the neurons of the brain, signal propagatiion takes place in the form of biophoton production. This statement is supported by recent experimental confirmation ...
