Altohami Mohammed M. Ahwidi Ihssin A. Abdalsamed Fatema A. Saleh In this study, photocatalytic activity of Ca-doped ceria (CDC) for malachite green (MG) degradation was investigated. CDC was successfully synthesized <em>via</em> co-precipitation method using ammonium oxalate as a precipitating agent. CDC was characterized using Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (XRD), UV-Vis spectroscopy, and scanning electron microscopy (SEM). The band gap energy (<em>E</em>_g) of CDC was found to be 3.96 eV. In addition, the factors affecting the photodegradation of MG including; irradiation time, photocatalyst dosage, initial dye concentration, and solution temperature were studied. The results revealed that CDC could degrade approximately 93% of MG dye at the concentration of 6 mg/L, irradiation time of 90 min, photocatalyst dosage of 0.1 g, and solution temperature of 35 °C. The obtained results indicate that CDC is a promising material for the photocatalytic applications and can be used to eliminate very toxic dyes such as MG. dye photodegradation Nanostructured materials doped ceria catalyst Semiconductor Optical properties 2020 01 01 1 14 https://www.ajnanomat.com/article_92856_7418c11b95a9cf12a1349f7c69c4acc9.pdf

Ferrous sulphate (FeSO₄) and sodium hydroxide were used as the precursor precipitating agent, respectively. The resultant specimens were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), ultra-violet visible spectroscopy (UV-Vis), fourier-transform infrared spectroscopy (FT-IR), soil test, biochemical, and phytochemical analysis. To test the effect of the synthesized specimen as the nanofertilizer in the seed germination and the growth, the sample was incorporated in to the red soil and the agronomical traits including plant height. Number of leaves were studied over a survival period of 75 days of the selected plant species <em>vigna mungo</em> using POT analysis. The plant samples were harvested, and then the biochemical and phytochemical studies were carried out for alkaloids, glycosides, flavonoids, phenols, steroids, protein and total chlorophyll content.

Ekpunobi Synthesis and characterization fluorine-doped tin oxide thin film using spray pyrolysis were coated on a glass substrate by varying the atomizing voltage. The XRD analysis was carried out and the results showed that the deposited films are polycrystalline in nature having the characteristic peaks of tetragonal structure of SnO₂. The observed peaks are (110), (101), (200), (211) and the preferential growth was found to be (110) direction. The I/V plots of the material deposited with 3.8 kV, 4.0 kV and 4.2 kV, which represent sample FT1-FT3 showed a non-linear plot and observed to be a non Ohmic semiconducting material. It was also noticed that as the atomizing voltage of the depositing material increases the thickness of the films increases. The resistivity of the material deposited increases and decreases at 4.0 kV as the atomizing voltage and thickness of the films increases. The electrical conductivity of the material deposited increases with respect to the atomizing voltage and thickness, respectively. It was observed that as the optical absorbance and reflectance decreased the wavelength of the incident radiation and transmittance enhanced as the wavelength of the incident radiation increased and the band gap energy of the films were observed to be at the range of 2.70-3.10 eV. spray pyrolysis Fluorine Tin Oxide XRD Optical properties 2020 01 01 47 57 https://www.ajnanomat.com/article_95889_ab742ed4236926fa6a22d7a06555166a.pdf

Thopate Biosynthesized silver nanoparticle is a very expanding and useful area. The reductant material in the plant extracts (leaves and bark) of Carissa carandas can produce silver nanoparticles. The plant leaves and bark extract of Carissa caranadas act as reducing and capping agent. Conventionally, chemical reduction is the most frequently applied approach for preparation of metallic nanoparticles; however, it might be hazardous to environment. In the present work we report eco-friendly, cost effective, and green approach for the synthesis of AgNPs by using 0.02 M AgNO₃solution and plant extracts (leaves and bark) of Carissa caranadas as reducing and capping agent. The synthesized nanoparticles were characterized using UV-VIS spectrophotomer, XRD, FT-IR, FE-SEM, and ICP-AES analysis. The biosynthesized silver nanoparticles showed a comparable antimicrobial activity against <em>Staphylococcus aureus</em>, <em>Escherichia coli,</em> and <em>Aspergillus niger</em>. Antimicrobial activity of the biosynthesized silver nanoparticles suggests their possible application in medical and pharmaceuticals industry.<br /><br /> Green synthesis Silver nanoparticles UV-Visible Spectrophotometer FT-IR ICP-AES Antimicrobial activity 2020 01 01 58 66 https://www.ajnanomat.com/article_96487_14cacc20f1655d9704fb85f9a12300ed.pdf

Mater. 2645-775X 2645-775X 2020 3 1 Mohammad Jahidul Islam Sunanda Paul Ajoy Kumer Md Nuruzzaman Sarker Incomputational chemistry through various basis sets, it is possible to design new molecules and discuss their use through their physical, chemical, biochemical studies. Chemical activity, biological activity, physical chemical activities can be diagnosed using density functional theory (DFT) for some palladium (II) complex ions. In this research study, the optimized dihydrazine palladium (II) complex ion (L01), di(1, 2- diaminemethane) palladium (II) complex ion (L02), di(1, 2- diamineethane) palladium (II) complex ion (L03), and di (1, 2- diamine propane) palladium (II) complex ion (L04) were simulated. Finally a comparative study of the palladium (II) complex ions were designed to show what ions are biologically more active using their QSAR data and orbital diagrams for HOMO and LUMO of the study of electronic properties. The HOMO-LUMO gap was also evaluated for chemical reactivity. The PIC50 value was calculated using the QSAR data where the value ​​of L01, L02, and L03 L04 where -15.757, 13.128, -6.111 and -5.955, respectively. If PIC50 is below -6, then the compound is said to be biologically active. It was found that, the L04 is highly biological active and L03 is almost similar to L04. Also, by enhancing the methyl group in palladium chain, the biological activity increased.

In this research work, Pregablin selected as a molecule for designing a emulgel using novel bio-functional agent and compared with standard polymer. This can be overcome by minimizing the dose and side-effects of API molecule used for various routes. The Pregablin loaded emulgel was prepared using novel bio-functional agent isolated from fruit pulp of <em>Musa acuminata</em> and with standard polymer (sodium alginate) with different ratios. The prepared formulations were evaluated for pH stability studies, % entrapment efficacy, <em>in-vitro</em> drug release and stability studies. The prepared emulgel was subjected to the best formulation based on comparison of above mentioned evaluation parameters, FM2 formulation was found to be the best formulation showing an R² value of 0.9487, T50% of 23.52 h and T80% of 60.22 h respectively. According to the release kinetics, the best fit model was Peppas Korsmeyer with Fickian Diffusion (Higuchi Matrix) as the mechanism of drug release.<em> Musa acuminata </em>provided the excellent stability for the formulation. The results revealed that, uaing <em>Musa acuminata</em> as bio-functional agent was safe and compatible with drug, so Pregablin loaded emulgel can be more affective for brain targeting upon trans-cranial administration.
