Time-Space Quantum Entanglement

In writing this article, we started with fundamental differences between Science and Mathematics. One is physical reality and other is abstract reality. By using exact mathematics to analyze approximated science, it is not a guarantee to obtain reliable and accurate solutions. Since we live in a Temporal Subspace, every substance within universe obeys the laws of science and the rule of time.  We will show instant Quantum Entanglement at a large distance only existed in a Timeless Space. But Timeless Space is not a Temporal Space and it cannot be existed within a temporal space. Particle Entanglement has to be at least two to tangle (it takes two to tangle). Since every entanglement involves time and space, Temporal and Spatial Entanglement can be defined. We have also shown that, Quantum entanglement is operating within the Certainty Limit of Heisenberg. In view of the Einstein’s Relativity, Quantum Entanglement can be extended to the Relativistic Regime; namely Relativistic Quantum Entanglement. © Anita Publications. All rights reserved.

Applications of high-resolution cavity ring-down spectroscopy
for non-invasive medical diagnostics

Manik Pradhan

Recent progress in the development of external-cavity quantum cascade lasers (EC-QCLs) in the mid-IR spectral region may be effective for high-resolution spectroscopic applications and multiple-trace gas detection. When QCLs are employed in the high-finesse optical cavity-enhanced spectroscopy techniques such as cavity ring-down spectroscopy (CRDS), the simultaneous and real-time detection of numerous trace species in exhaled breath are possible with ultra-high sensitivity and molecular specificity. In this short article, we briefly describe the basic principle of CRDS technique, its principal advantages and one of the potential application areas of CRDS method, in particular in the field of non-invasive medical diagnosis of diseases through breath analysis. © Anita Publications.

Effect of sputtering power on structural, morphological and optical properties of Zinc oxide thin films

In this work, we report the synthesis of zinc oxide (ZnO) thin films using reactive magnetron sputtering technique and the effect of sputtering power (40, 60 and 80 W)  on their structural, morphological and optical properties. The  newly synthesized thin films were characterised using powder X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), Energy dispersive X-ray analysis (EDXA) and UV-NIR visible spectroscopy. XRD analysis exhibited the hexagonal wurtzite structure with increase in average crystallite size and hydrophobicity with the increase of sputtering power. The contact angle of ZnO thin films were determined by contact goniometer. ZnO thin films deposited with low sputtering power (40W) exhibit higher optical transmittance (T~82 %) and larger band gap (~3.3 e V) as evident from transmittance measurements in the wavelength range from 300 to 800 nm. © Anita Publications.

Rahul Kaushik and P P Pathak
Department of Physics, Gurukula Kangri Vishwavidyalaya, Haridwar-249 404, india

The internal electric fields and specific absorption rate (SAR) are calculated for the human skin tissue due to cylindrical wave-front radiated from vertical sector antenna used in transmission tower of a mobile phone base station. The calculations have been made for Global System for Mobile communication (GSM), for 2G (GSM900) 935 - 960 MHz, for 2G (GSM1800) 1810 – 1880 MHz and 2110 – 2170 MHz for 3G. The obtained values are compared with the safe limits of exposure to electromagnetic radiations provided by the international agencies and found that the radiation of different frequencies come under the harmful limit for humans. © Anita Publications.

Computational Investigations of quinacridone on silver and gold clusters:
Application to Nonlinear Optical and OLED devices

U Reeta Felscia, Beulah J M Rajkumar*
PG & Research Department of Physics, Lady Doak College, Madurai 625002, India

Interaction of quinacradone (QA) on silver and gold clusters has been investigated using computational methods. Hyperpolarizabilities computed theoretically point towards the possible use of QA adsorbed on Ag3 and Au3 in the rational design of NLO devices. The red shift in the simulated UV-Vis spectra confirms the process of adsorption on metal clusters, which is mainly due to the electrostatic interaction between the metals and QA. This interaction induces variations in the structural parameters of QA, which are confirmed by the NBO analysis and the MEP plot. Reduction in the hole reorganization energy along with the increment in hyperpolarizability suggest that QA adsorbed on silver cluster can be used as an effective material in OLED and NLO devices.© Anita Publications.
