Discrete direct current (DC) resistivity sounding still remains a convenient and popular tool for groundwater studies in wadi environments in Egypt, such as Wadi Feiran. It is considered one of the main sources for groundwater in Southern Sinai, Egypt. The stratigraphic make-up of such wadi is complex with the presence of near surface inhomogeneiti...

In this present work, we adopted a modified lemon juice-involved combustion method to prepare MgFe2O4 nanoparticles (MgFNPs). The prepared MgFNPs are subjected to annealing treatment at different temperatures. The synthesized and annealed MgFNPs have been studied using various techniques to analyze their structural, morphological and biomedical act...
Mosquito act as a vector for variety of deadly diseases. In this study, larvicide activity was investigated in relation to Aedes aegypti ( A. aegypti ) and Culex quinquefasciatus ( C. quinquefasciatus ) of synthesised silver nanoparticles (AgNPs) of the Pila virens ( P.virens ) shell extract. The characterization techniques UV–vis spectral, Fourier...

Toxoplasma gondii is an obligate intracellular pathogen that infects warm-blooded animals and humans. However, side effects limit toxoplasmosis treatment, and new drugs with high efficiency and low toxicity need to be developed. Natural products found in plants have become a useful source of drugs for toxoplasmosis. In this study, twenty natural co...

Escherichia coli chaperonin GroEL, which is a large cylindrical protein complex comprising two heptameric rings with cavities of 4.5 nm each in the center, assists in intracellular protein folding with the aid of GroES and adenosine triphosphate (ATP). Here, we investigated the possibility that GroEL can also encapsulate metal nanoparticles (NPs) u...

Aluminide coating is prepared on K438 Ni-based superalloy by pack cementation. The hot corrosion test of as-received and pre-oxidation aluminide coating in Na2SO4 salt are carried out at 1050°C. The coating morphologies, phase composition, and corrosion products are characterized by XRD, SEM, EDS, and TEM. The conclusion is that the pre-oxidation a...

Here we report the electrospinning synthesis of Cd-substituted Ni-Co ferrite Ni0.5Co0.5-xCdxFe1.78Nd0.02O4 (x ≤ 0.25) nanofiber (NFs) with a very low concentration of Nd as a dopant. The structure and surface morphology of the Ni0.5Co0.5-xCdxFe1.78Nd0.02O4 (x ≤ 0.25) NFs were analyzed by X-ray powder pattern (XRD), transmission and scanning electro...

An alternative green approach through which nanoscience/nanotechnology could be applied in the industry is being demonstrated in this study. Ethanol extracts of Allium cepa peels (Et-ACPE) is used to mediate the synthesis of silver nanoparticles (Et-AgNPs) at room temperature. Stable crystalline, monodisperse and non-agglomerated spherical NPs with...

Helium bubbles, which are typical radiation microstructures observed in metals or alloys, are usually investigated using transmission electron microscopy (TEM). However, the investigation requires human inputs to locate and mark the bubbles in the acquired TEM images, rendering this task laborious and prone to error. In this paper, a machine learni...
