Antibacterial Properties of Polysulfone Membranes Blended with Arabic Gum.
Published 2019“…These changes were due to the amphiphilic properties of AG macromolecules that contained negatively charged hydrophilic residues. A pronounced decrease in bacterial attachment was seen in the field emission scanning electron microscopy (FESEM) images for PS/AG membrane samples compared to both commercial (Microdyn-Nadir) and bare PS (without AG) membranes. …”

The Formation of Sulfide Scales on Carbon Steel in Saturated H2S
Published 2020“…The electrochemical reaction commonly contains three stages: first, the reactant transported from the solution (bulk) to the metal surface; then the transfer of the charge reaction on the surface, followed by the reaction product transported away from the iron surface to the bulk solution or the formation and development of the corrosion product which then can decrease the corrosion rate. Development of a robust corrosion model to predict the corrosion process in H2S these requires a mechanistic understanding of all these elements. …”

Self-assembled zirconia nanotube arrays: Fabrication mechanism, energy consideration and optical activity
Published 2014“…The effects of anodization time, applied voltage, solvent composition, as well as fluoride and water content are investigated. The length of the resulting nanotubes showed a strong dependence on the concentration and mobility of F - ions, whilst O2- ion content was found to play a key role in controlling the nanotube wall thickness. …”

Effect of Verbal Encouragement on Performance and Affective Responses in Male Sport Science Students during Sprint Modalities
Published 2024“…The assessed parameters comprised physical performance, rating of perceived exertion (RPE), and a feeling scale. Post hoc test analysis indicates a significant increase in physical performance during VETS and VESS conditions compared to the control condition due to a decrease in sprint in line 20 m (VETS: p < 0.001, d = 0.55; VESS: p = 0.016, d = 0.41), sprint 10*2 (VETS: p < 0.001, d = 0.64; VESS: p = 0.05, d = 0.36), and sprint L (VETS: p = 0.001, d = 1.19) times compared to the control condition. …”

Influence Of Surface Finish Parameters On Corrosion Of Zinc
Published 1989“…Also, it was found that the increase in surface roughness has two connecting effects. The first leads to a decrease in corrosion potential due to a decrease in the cathodic surface area while the second leads to an increase in corrosion potential due to a decrease in the peak to valley distances of surface irregularities…”
