The Rotational-Translational Spectra of N2 and CO2 and their Mixtures with Argon: Experimental Investigation | Chapter 10 | Research Trends and Challenges in Physical Science Vol. 6

As a result of molecular pair collisions, the rotational-translational absorption spectra of carbon dioxide, nitrogen, and their mixes with argon in the wavelength range 20-190 cm-1 are acquired and analysed. The terahertz spectra of N2 and CO2 are shown to be dominated by quadrupole interactions, as opposed to absorption in noble gas combinations. The integrated

Study on Application of Advance Constrained Simplex Method for MIMO Systems in Quantum Communication Networks | Chapter 9 | Research Trends and Challenges in Physical Science Vol. 6

The study and exploration of Multiple-Input Multiple-Output (MIMO) wireless access technology has been spurred by the global bandwidth shortage in the wireless communication sector (MIMO). Massive MIMO is a critical enabling technology for Quantum Communication Networks, as it combines antennas at both the transmitter and receiver to give high spectrum and energy efficiency while requiring

Applied Aspects of Classical Thermodynamics. Part II: Some Consequences of Expressions for the Heat of Transition of Phase Transitions of the First Kind | Chapter 8 | Research Trends and Challenges in Physical Science Vol. 6

It is proven that there is no critical point on the melting line using the previously established formulas for the heat of melting and the heat of evaporation. At a critical point, an expression relating thermodynamic parameters is found. The estimated derivative at the critical point changes by only one or two percent, as illustrated.

Study on Thermodynamic Constant of Time Passage | Chapter 7 | Research Trends and Challenges in Physical Science Vol. 6

The study of time has a long and illustrious history, and it is still continuing strong today. Because Isaac Newton coined the term “time” in the 17th century, it could not possibly be related to thermodynamics. Newton’s concept of time is still popular because it captures the universal human sense of time passing. Only the

A Suggestion for a Relevant Conceptual Basis in Biophysics | Chapter 6 | Research Trends and Challenges in Physical Science Vol. 6

For the time being, biological processes are characterised using thermodynamics, mechanics, dynamic systems theory, and other theoretical equipment. A proposal to broaden the theoretical foundation of biophysics by adding new measurable variables and regularities is discussed here. It is proposed a new conceptual basis for describing living objects in their whole and overall reaction. If

Study of the Modification of the High-Latitude Ionosphere by the Ground-Based Ionospheric Heater at the Nighttime: A Simulation Approach | Chapter 5 | Research Trends and Challenges in Physical Science Vol. 6

The goal of this study is to see how high-power, high-frequency radio waves pushed into the ionosphere at high latitudes affect ionospheric plasma characteristics. The ground-based ionospheric heater at Tromso, Scandinavia, is used to calculate three-dimensional distributions of ionospheric parameters using a mathematical model of the high-latitude ionosphere developed earlier at the Polar Geophysical Institute.

LRS Bianchi Type-II Cosmic Domain Wall in Modified Theory of Gravitation | Chapter 4 | Research Trends and Challenges in Physical Science Vol. 6

In the framework of Saez and Ballester’s scalar-tensor theory of gravity, LRS Bianchi-Type-II space time is examined in the presence of thought domain walls (Phys.Lett. A 113:467,1986). It is offered an exact cosmological model that represents a stiff domain wall. The model’s physical and kinematic features are also discussed. Author(S) Details R. SanthikumarAditya Institute of

Study on Highly Biocompatible Porous NiTi Alloys | Chapter 3 | Research Trends and Challenges in Physical Science Vol. 6

Medical equipment including as catheters, pacemakers, and stone removal mesh have shown to be great candidates for nickel titanium alloys. However, there are some issues with the shape and size alterations that are required to meet the requirements of the applications. Porosity for bone replacement, radiopacity, super elasticity, and fatigue strength are all areas where

Parameters Defining the Interband Absorption Coefficient in Amorphous Semiconductors: A Recent Study | Chapter 2 | Research Trends and Challenges in Physical Science Vol. 6

The interband absorption spectra of amorphous semiconductors are explored using theoretically developed formulas. It is shown that the proportionality coefficient and the energy width of the mobility gap of these spectra may be calculated using experimentally acquired interband absorption spectra. The energy width of the mobility gap expands as the amount of selenium in an

Characterization of Plasma Polymerized PANI Films | Chapter 1 | Research Trends and Challenges in Physical Science Vol. 6

Pulsed-plasma polymerization was used to make the polyaniline (PANI) thin film. Ideal conditions were obtained after studying the effects of substrate position, pressure, and the number of plasma pulses on the film growth rate. The structural and optical properties of the PANI thin film were investigated using UV-vis, FTIR, and optical absorption spectra. Electrical conductivity
