About Cover

In current pandemic, as there is no approved specific antiviral agent for coronavirus disease (COVID-19) available till to date; Ayurveda has emerged out as effective tool to control the prevailing pandemic at initial stage mainly by gearing up the immune system. The cover photo of this February 2021 issue of Advanced Materials Letters is inspired by the Perspective Article by Mangala et al., on “COVID-19: A Significant Revival Approach - Concurrent Case Study in India”.

Article 3. Viral Evolution of Multiple Coronavirus Genomes on Genomic Index Maps

The third article of this issue is published by Jeffrey Zheng and Minghan Zhu from Yunnan University, China and focused on genomic index maps related to evolutionary aspects. Here author discussed about a novel scheme, which represented to arrange various coronavirus genomes by two genomic indexes as 2D maps. In this article for a genome, two unique invariants of genomic indexes provide an absolute position on a 2D region in real measurements. Samples of seventeen coronavirus and twenty-six SARS-CoV-2 genomes from various countries are selected. This provides an efficient scheme to identify variations of SARS-CoV-2 strains for better identifications on both complicated coronavirus clusters and SARS-CoV-2 group of viral evolution in intermediate and original hosts on selective environments.

Article 4. Solution Combustion Synthesis and Energy Transfer in Tunable Phosphor

The fourth article of the issue is published by S.P. Puppalwar et al from Kamla Nehru Mahavidyalaya, India and R.T.M. Nagpur University, India. Article described that Tb3+/Sm3+ single as well as co-doped LaMgAl11O19 (LMA) phosphors have been synthesized by a low-temperature solution combustion method. The X-ray diffraction pattern, photoluminescence properties and energy transfer (ET) processes between rare earth (RE) ions, were investigated in detail. Here, LMA: Tb3+, Sm3+ phosphors exhibited the emission peaks in the blue (5D3→7FJ = 5, 4, 3, and 2), green (5D4→7FJ = 6, 5, and 4), and orange-red (4G5/2→6HJ = 5/2, 7/2, and 9/2) regions under the excitation wavelength of 375 nm. As a consequence of fine-tuning of the emission composition of the Tb3+ and Sm3+ ions, multicolor emitting luminescence properties can be achieved in a single host lattice LMA.

Article 5. Influence of Fe3O4 and CTABr on the Rate of Degradation of Methylene Blue by H2O2

The fifth article reported by the Mohd Shaban Ansari et al. from Aligarh Muslim University, India and King Abdul Aziz University, Saudi Arabia. Here author studied the kinetics of the oxidation of methylene blue (MB) by H2O2 in the presence of iron oxide nanoparticles. The nanoparticles of iron oxide (Fe3O4) were synthesized and characterized physico-chemical techniques. The XRD studies showed its crystalline nature. The Fe3O4 nanoparticles enhanced the rate of degradation of MB. The oxidation rate increased with the increase in Fe3O4. At pH 3, the maximum rate of oxidation of MB was observed. The rate of reaction increased with the increase in [H2O2] in the absence of Fe3O4. But in the presence of Fe3O4, the rate constant versus [H2O2] showed peaked behaviour. The CTABr increased the rate of oxidation of MB by H2O2 in the presence of Fe3O4 nanoparticles.

Article 6. Effect of Sulfurization Temperature on RF Sputtered MoS2 Thin Film

In the sixth article, V. Thiruvengadam et al. From National Institute Of Science Education And Research (NISER), India worked on MoS2 Thin Film. Here, author report a facile way to fabricate stoichiometric, crystalline and star shaped MoS2 film. In this work, ultra-thin MoS2 films were fabricated by two step process (i) RF sputtering of MoS2 target followed by (ii) sulfurization to improve stoichiometry and crystallinity. The study results confirm that as sputtered MoS2 films are discontinuous, amorphous in nature and it crystalizes into a layered structure during sulfurization at temperature ≥ 750°C. Here, star shapes can provide more surface area/edges that can be exploited to enhance the efficiency of gas sensors.

Article 7. Fatigue Analysis for Fe-34.5Mn-l0Al-0.76C Tidal Turbine Blades using Rainflow Algorithm

The seventh article of the issue investigates the effect of the environmental conditions (seawater mean thrust force and flow velocity) on a tidal turbine for different thicknesses mathematically. Eisa A. Almeshaiei et al. from Public Authority for Applied Education and Training, Kuwait; Alexandria University, Kuwait and Heriot Watt University, Kuwait published this article. This study had been achieved through predicting the fatigue stresses applied on the turbine for different conditions using Rainflow algorithm. Fe-34.5Mn-l0Al-0.76C alloy had been selected in this study. Obtained results showed that, increasing thickness of the blade resulted in increasing the turbine lifespan for each studied flow velocity and thrust forces. Here, optimizing the blade thickness would help in maximizing the energy conversion efficiency of the turbine as well, as a lightweight blade would be able of generating electricity higher than heavy ones.

Article 8. Modelling for the Study of Thermoelastic Properties of Nanoparticles

In the eighth article, author proposed a very simple model to predict the thermoelastic properties of nanosolid, nanowire and nanofilm of Selenium, Copper, Silver, Lead, Tin, Zinc and Nickel elements with the variation of temperature at their different sizes. This article is published by the Shridhar Pathak et al. MMM University of Technology, India and Government Degree College, India. In this study, it is observed that compression (V/V0) increases with temperature in nanospheres, nanowires and nanofilms of the considered elements. Here, author found that the compression decreases with an increase in size. The thermal expansivity and bulk modulus vary with shape and size and shows significant deviation in thermoelastic parameters.

Article 9. Potato Starch Edible Films as Environmentally Friendly Carriers for Model Drug: In vitro Release Study

In the ninth article of the issue, in vitro release model for drug is highlighted. This study is published by Fateh Eltaboni et al. from University of Benghazi, Libya and Bright Star University, Libya. This work aims to introduce edible starch films-based carriers for supporting the release of fluorescein as a model drug. Starch is a vital plant polymer used in thousands of food and non-food products. Physical modification for potato starch carriers (PSS) was done by incorporating glycerol and low-density polyethylene (LDPE) molecules. It was found that PSS-LDPE is spread better than LDPE at physiological temperature, While PSS formed faster edible film than LDPE and PSS-LDPE. Here, amounts of dye released from PSS and PSS-LDPE films were higher than that of fluorescein dispersed in starch suspension in buffer solution (pH 7.5) at 37oC.
