Objective: The present report describes the green synthesis of Zinc oxide nanoparticles (ZnO NPs) using Argemone maxicana leaf extract by an eco-friendly approach. Also, the in-vitro cytotoxicity of prepared ZnO NPs against the cardiac cell lines of Sahul India Catla catla fish (SICH) was studied. Methods: ZnO NPs were prepared by using Argemone maxicana leaf extract as reducing and stabilizing...

We test several convolution and deconvolution models on phase curves at small phase angles ð0:0011oao1:51Þ that have the highest phase angle sampling to date. These curves were provided by cameras onboard several NASA missions (Clementine/UVVIS, Galileo/SSI and Cassini/ISS) when the Sun had different apparent angular radii (a 1⁄4 0:2661, 0.0511, 0.0281). For the smallest phase angles, the brigh...

A liquid chromatographic method coupled with UVVis and photodiode–array detection for the determination of nitrofuran residues: nitrofurazone, nitrofurantoin, furazolidone, and furaltadone in water was developed and validated. Confirmation of the identity of nitrofurans was performed by liquid chromatography–mass spectrometry with atmospheric pressure chemical ionization interface. The nitrofur...

[1] High-alumina (HA) mare basalts are a unique group of the lunar sample collection. Sample geochemistry indicates that these basalts are derived from sources composed of late-stage cumulates from the Lunar Magma Ocean (LMO). Their aluminous nature suggests their sources contained significant plagioclase, which has implications regarding the efficiency of plagioclase separation from earlier fo...

Introduction: In February 1994, the Clementine spacecraft began orbiting the Moon with a suite of instrumentation that generated millions of images of the lunar surface. This instrumentation package included an ultraviolet-visible (UVVIS) imager that collected 5 spectral wavelengths (0.415, 0.75, 0.90, 0.95, and 1.00 μm) and a near-infrared (NIR) imager that collected 6 spectral wavelengths (1....

Impact basins are the dominant landforms on lunar surface, and their geological evolution varies. This research studied diversity in of three impact basins: Dirichlet–Jackson Basin, Nectaris Orientale Basin. First, regional topography geomorphology were using SLDEM2015 digital elevation model (DEM). Clementine ultraviolet–visible (UVVIS) data Moon Mineralogy Mapper (M3) used to study chemical c...

We examine a dome within the boundary between Fracastorius crater and Mare Nectaris. The has noticeable vent structure appears to be perpendicular wrinkle ridges in southern Nectaris basin. spectral signature of this dome, derived from Clementine UVVIS Chandrayaan-1 M3 reflectance data, revealed that low TiO2 content primarily basaltic material. Using altimeter we measured diameter 28.6 km, wit...

در این پژوهش، سنتز نانوبیوالیاف شیشه¬ای مزومتخلخل در دو سیستم sio2-cao-p2o5-tio2 و sio2-cao-p2o5 به روش الکتروریسی هم¬محور مورد بررسی قرار گرفت و پارامترهای غلظت و ولتاژ اعمالی در فرآیند الکتروریسی بهینه شد. سطح ویژه و حجم حفرات نانوبیوالیاف در دو سیستم sio2-cao-p2o5 و sio2-cao-p2o5-tio2، پس از عملیات حرارتی اندازه¬گیری شد. در مرحله بعد جهت بررسی رسانش دارو، از داروی مدل ایبوپروفن استفاده و این...
