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><sub>g</sub>) 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.https://www.ajnanomat.com/article_92856_7418c11b95a9cf12a1349f7c69c4acc9.pdfdye photodegradationNanostructured materialsdoped ceria catalystSemiconductorOptical propertiesengSami Publishing Company (SPC)Asian Journal of Nanosciences and Materials2645-775X2588-669X2020-01-0131152310.26655/AJNANOMAT.2020.1.293007Antifungal activity of biosynthesized CuO nanoparticles using leaves extract of Moringa oleifera and their structural characterizationsKhanderao Pagar[email protected]1Suresh Ghotekar[email protected]2Trupti Pagar[email protected]3Amol Nikam[email protected]4Shreyas Pansambal[email protected]5Rajeshwari Oza[email protected]6Dnyaneshwar Sanap[email protected]7Harshal Dabhane[email protected]8Department of Chemistry, KKHA Arts, SMGL Commerce and SPHJ Science College, Chandwad, Savitribai Phule Pune University, Maharashtra 423 101, IndiaDepartment of Chemistry, Sanjivani Arts, Commerce and Science College, Kopargaon 423 603, Savitribai Phule Pune University, Maharashtra, IndiaDepartment of Chemistry, G.M.D Arts, B.W Commerce and Science College, Sinnar, 422 103, Savitribai Phule Pune University, Maharashtra, IndiaDepartment of Chemistry, GMV Science College, Tala 402 111, University of Mumbai, Maharashtra, IndiaDepartment of Chemistry, S.N.

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 SnO<sub>2</sub>. 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.https://www.ajnanomat.com/article_95889_ab742ed4236926fa6a22d7a06555166a.pdfspray pyrolysisFluorineTin OxideXRDOptical propertiesengSami Publishing Company (SPC)Asian Journal of Nanosciences and Materials2645-775X2588-669X2020-01-0131586610.26655/AJNANOMAT.2020.1.696487مقاله پژوهشیBiosynthesis of silver nanoparticles using leaf and bark extract of indian plant carissa carandas, characterization and antimicrobial activitySatish B.

IndiaBiosynthesized 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 AgNO<sub>3 </sub>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 <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 />https://www.ajnanomat.com/article_96487_14cacc20f1655d9704fb85f9a12300ed.pdfGreen synthesisSilver nanoparticlesUV-Visible SpectrophotometerFT-IRICP-AESAntimicrobial activityengSami Publishing Company (SPC)Asian Journal of Nanosciences and Materials2645-775X2588-669X2020-01-0131678110.26655/AJNANOMAT.2020.1.796587مقاله پژوهشیComputational approach of palladium (II) complex ions with binuclear diamine ligands thermo-physical, chemical, and biological properties: a dft studyMohammad Jahidul Islam[email protected]1Sunanda Paul[email protected]2Ajoy Kumer[email protected]3Md Nuruzzaman Sarker[email protected]4Department of Physics, European University of Bangladesh, Dhaka-1216, BangladeshDepartment of Biochemistry and Molecular Biology, University of Chittagong, Chittagong,Hathazari-4334, BangladeshDepartment of Chemistry, European University of Bangladesh, Dhaka-1216, BangladeshDepartment of Physics, European University of Bangladesh, Dhaka-1216, BangladeshIncomputational 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.https://www.ajnanomat.com/article_96587_1dc73366f5706319b23d5105850cd227.pdfPalladium (II)DFTQSARHOMOLUMOVibrational spectroscopyElectronic spectroscopyengSami Publishing Company (SPC)Asian Journal of Nanosciences and Materials2645-775X2588-669X2020-01-0131829210.26655/AJNANOMAT.2020.1.896791مقاله پژوهشیAn innovative approach delivery of anticonvulsant via transcranial route using a smart bio-functional agent cum musa acuminataSatheesh Madhav[email protected]1Abhinav Dewari[email protected]2Yogita Tyagi[email protected]3Faculty of Pharmacy, DIT University, Mussoorie diversion Road, Dehradun-248009, Uttarakhand, IndiaFaculty of Pharmacy, DIT University, Mussoorie diversion Road, Dehradun-248009, Uttarakhand, IndiaFaculty of Pharmacy, DIT University, Mussoorie diversion Road, Dehradun-248009, Uttarakhand, IndiaEpilepsy is a central nervous system disorder (neurological disorder) in which the nerve cell activity in the brain becomes disrupted, causing unprovoked, recurrent seizures or unusual behavior, sensations or even unconsciousness. 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 R<sup>2</sup> 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.https://www.ajnanomat.com/article_96791_c49734013b2c46b91c9e5ab7435a3c4e.pdfBio-functional agentEmulgelEpilepsyMusa acuminataPregablin
