Quantum Information Processes in Protein Microtubules of Brain Neurons
- 2016
-
Ingår i: 3rd International Conference on Nanotechnologies and Biomedical Engineering. - Singapore : Springer Singapore. - 9789812877369 - 9789812877352 ; , s. 245-249

Konferensbidrag (refereegranskat)abstract
- We study biologically 'orchestrated' coherent quantum processes in collections of protein microtubules of brain neurons, which correlate with, and regulate, neuronal synaptic and membrane activity. In this situation the continuous Schrodinger evolution of each such process terminates in accordance with the specific Diosi-Penrose (DP) scheme of 'objective reduction' ('OR') of the quantum state. This orchestrated OR activity ('Orch OR') is taken to result in moments of conscious awareness and/or choice. We analyze Orch OR in light of advances and developments in quantum physics, computational neuroscience and quantum biology. Much attention is also devoted to the 'beat frequencies' of faster microtubule vibrations as a possible source of the observed electro-encephalographic ('EEG') correlates of consciousness.

Influence of vacancy and adatom defects on the optoelectronic properties of monolayer GeS
- 2021

Ingår i: AIP Conference Proceedings. - : AIP Publishing.

Konferensbidrag (refereegranskat)abstract
- Two-dimensional (2D) GeS monolayer having a similar structure to phosphorene draws research attention due to its novel and interesting properties which may be used as energy harvesting applications. The structural defects are an efficient way to modulate the properties of the materials. In the present work, the structural, electronic and optical properties of pristine GeS, defected system with sulfur vacancy as well as oxygen substitution on the same place are studied. The S-vacancy in GeS monolayer significantly reduces the electronic bandgap and also displayed the remarkable changes in optical properties. Again, the replacement of S atom to O atom on GeS monolayer effectively maintains the electronic properties as well as optical properties which shows very close to pristine system. From these investigations, we conclude that the similar group of atoms not effectively changes the properties of layered monolayer materials and vacancy in GeS monolayer significantly changes the properties of materials which can be used as high performance nanoelectronics and optoelectronics applications.
