The first article of the issue solely talks about the mechanistic approach to understanding the characteristic properties of the deadliest virus (COVID-19). This article is authored by Chander Amgoth, et al. from Zhejiang University, China and Tel Aviv University, Israel. Here, the author described that the nano-sized (160-200 nm, in diameter) virus along with the spikes (length ~10 nm) play crucial role in infection. Mutations lead to an increase in population density and glycoprotein of spike spindles fuses the surface of lung cells through the binding affinity. Inflammation caused because of the replicated complex of virus blocks the passage of gases O2, CO2 which lead to severe cough and respiratory problems. This unusual phenomenon of pneumonia leads to death. Further, massive computing is needed to understand the exact detrimental consequences of COVID-19 followed by the drug and vaccine development.

The fourth article is reported by Yao Lu et al., from Nanjing University, China. Here authors discussed double perovskite Ba2FeNbO6 (BFN) powders, which were synthesized by molten salt method. The present work offers an effective approach to tuning the Eg of BFN powders, which find promising applications in the fields of photovoltaic and photocatalytic devices.
In this article, optical properties were characterized by UV-Vis absorption spectra, and the band gaps (Eg) were determined to be 2.12 - 2.25 eV. Here, the authors’ indicate that the overlapping between the O-2p and Fe-3d orbitals is changed, making the Eg values changed. A small absorption shoulder with absorption edge at 650 nm (Eg ~ 1.91 eV) observed in the BFN powders, was ascribed to the d-d electronic transition from the Fe 3d-b2g to Fe 3d-b1g orbitals, which were formed by further splitting of Fe 3d orbitals in the distorted octahedral field.

The seventh article emphasizes more about the requirement of material that has high thermal conductivity as well as suitable electric insulating properties. Such materials are required for electronic components and solar panels. This article is authored by Sumit Sharma et al., from Dr. B R Ambedkar National Institute of Technology, India. In this study, the multi-scale modeling of epoxy (bisphenol-A) reinforced alumina composite has been performed using BIOVIA Materials Studio and Abaqus. Modeling has been done for varying volume fraction (Vf) of alumina. Heat transfer analysis has been done using Abaqus/Explicit. It was found that the thermal conductivity first increased till Vf = 20% and then decreased. When the concentration of alumina was increased further after Vf = 20%, the orientation of alumina particles changed from being in-plane to random, resulting in a fall in the values of thermal conductivity.
