The objective of this work is to study Ɓ-types of contraction mappings in the settings of partial metric space and establish fixed point results. As a result, a fixed point theorem has been established for a pair of Ɓ-type contraction mappings with a unique common fixed point. The study's main findings, in particular, expand and extend a fixed point theorem first proposed by Bijender et. al. in 2021.

This article analyses the influence of heat generation and thermal radiation on steady hydromagnetic fully developed natural convection flow in a vertical micro-porous–channel in the presence of viscous dissipation. The governing ordinary differential equations, exhibiting the physics of the flow formation are displayed. Using the relevant non–dimensional variables, the governing equations are transformed into their corresponding non–dimensional form and then solved exactly by employing the perturbation technique. The influence of different admissible parameters such as fluid wall interaction parameter, Knudsen number, heat generation parameter, thermal radiation parameter, magnetic parameter, Eckert number, and permeability parameter on the fluid velocity, temperature, skin friction coefficient, and heat transfer coefficient at the micro-porous–channel surfaces is discussed with the aid of line graphs and tables.

The micro canonical ensemble (MCE) represents an isolated system having fixed energy. The nature of energy in MCE is always a subject of discussion. In this paper we are distinguishing the energy possessed by the system and the energy offered by the system for measurement in MCE. This we hope will help the learners of statistical mechanics to have a more understanding of MCE.

Stars are not just useful in the pursuit of astronomy, their importance to us is fundamental. However, the true nature of stars remained a mystery for centuries. Then, through years of hard work we presently do have the tool using which we can actually study and understand the stars. That tool is spectroscopy. For the past few years, intense research in the field of stellar spectroscopy is being carried out at the CHRIST (Deemed to be University) too. This article, written in popular style, provides an understanding of how the exciting field of spectroscopy -- the language of stars -- gradually developed, thus helping humanity to gain a good understanding about stars and astronomy as a whole. The article intends to provide motivation to young students, especially of UG level, who dreams to pursue astronomy research in future to do research in this exciting field.

Over time, pre-main-sequence (PMS) stars evolve into main-sequence (MS) stars. Stars evolving from PMS to MS phase is a significant subject of research that aims to better understand stellar phases and their properties. Existing literature shows a lack of study of stars in between PMS and MS phase. 'We focused on what belongs in the midst of these two phases. Classical Be (CBe) and Herbig Ae/Be (HAeBe) stars, corresponding to MS and PMS phases, are two well known categories of emission-line stars. Through optical and infrared photometric analysis of a sample of 2167 CBe and 225 HAeBe stars, we identified 98 such rare stars which are in transition between PMS and MS phase. Those rare stars are termed as 'Transition Phase' (TP) candidates in our study. Using the machine learning approach, the potential of the identified TP candidates was verified.

Structural figure prints for identifying the molecules in graphene layers of various carbon materials can be obtained from Raman spectroscopy. In this review we have discussed the Microraman analysis of few- layer graphenes from different carbon samples originating from hydrocarbon and agricultural derivatives. This review also shows the crystallite size dependence of the D-band in the Raman spectrum. Deconvolution of broad signal peaks is done to get multiple overlapping bands giving information about various aspects of defects and structure of graphitic materials. This review also contains information regarding different types of defects that can be analyzed using Raman spectroscopy.

One of the most distinctive inventions in the world of nanotechnology is the carbon nanotube (CNT). Many scholars around the world have been studying carbon nanotubes (CNTs) over the past two decades due to their enormous potential in a variety of sectors. Single-wall CNTs with dimensions in the nanometer range are commonly referred to as carbon nanotubes. Carbon nanotubes are also known as multi-wall CNTs, which are made up of nested single-wall CNTs that are weakly bonded together in a tree ring-like structure by van der Waals interactions. Tubes having an unknown carbon wall structure and diameters smaller than 100 nanometers are also referred to as carbon nanotubes. A carbon nanotube's length is often substantially longer than its diameter, according to standard manufacturing methods. Carbon nanotubes are capable of exhibiting a variety of remarkable properties. CNTs have distinct electrical, mechanical and optical properties that have all been thoroughly investigated. The properties and applications of carbon nanotubes are the focus of this review.
