Saleh Department of Chemistry, Faculty of Science, Sebha University, Sebha, Libya fatema6288@gmail.com 10.26655/AJNANOMAT.2020.1.1 In this study, photocatalytic activity of Ca-doped ceria (CDC) for malachite green (MG) degradation was investigated. CDC was successfully synthesized via 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 (Eg) 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 https://www.ajnanomat.com/article_92856.html https://www.ajnanomat.com/article_92856_7418c11b95a9cf12a1349f7c69c4acc9.pdf

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 https://www.ajnanomat.com/article_95889.html https://www.ajnanomat.com/article_95889_ab742ed4236926fa6a22d7a06555166a.pdf

India srthopate@gmail.com 10.26655/AJNANOMAT.2020.1.6 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 AgNO3 solution 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 Staphylococcus aureus, Escherichia coli, and Aspergillus niger. Antimicrobial activity of the biosynthesized silver nanoparticles suggests their possible application in medical and pharmaceuticals industry.

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 Musa acuminata and with standard polymer (sodium alginate) with different ratios. The prepared formulations were evaluated for pH stability studies, % entrapment efficacy, in-vitro 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. Musa acuminata provided the excellent stability for the formulation. The results revealed that, uaing Musa acuminata 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.
