UAE Spergula Fallax (lowe) E.H.L Krause Aqueous Extract as a Corrosion Inhibitor for Mild Steel in HCl Solution
The aim of this research is to study the effect of UAE Spergula fallax (lowe) E.H.L Krause aqueous extract on the corrosion inhibition of mild steel in 1.0 M HCl solution by weight loss experiments, which will serve researchers in the field of corrosion. Weight loss measurements were carried out on mild steel specimens in 1.0 M HCl containing various concentration (ranging from 5.0 to 0.0005 g/L) of the UAE Spergula fallax (lowe) E.H.L Krause aqueous extract at temperature ranging from 303 to 343 K. The aqueous UAE Spergula fallax was found to be a highly efficient inhibitor for mild steel in 1.0 M HCl, reaching 90.23% at 5.0 g/L and 303 K. the corrosion rate decreases as the concentration of aqueous extract of UAE spergula fallax (lowe) E.H.L Krause aqueous extract increases.
Robustness of gold nanoparticles under physiological conditions
Scientific research on nanoparticles is intense as they have many potential applications in medicine, physics, optics, and electronics. The U.S. National Nanotechnology Initiative offers government funding focused on nanoparticle research.The aim of this research is to check the robustness of gold nanoparticles in different solutions of pH, concentrations of NaCl, and %NaCl. Our nanoparticles were the first that were robust under certain pH's, and we reached our goal that the nanoparticles are stable but not 100%, because in pH 1.8 the solution is too acidic, which forms instant aggregation.We studied different physiological pH's and how some diseases affect these physiological conditions, as for NaCl we studied robustness at normal percentage and higher percentages and our nanoparticles were robust in both cases which indicates good results
Antagonist effect of divalent ions towards Azorubine dye toxicity to Serum Albumin
Serum albumin is one of the important proteins in our blood circulation, it transports many essential biomolecules in our body. One of the most commonly and widely used food colors in UAE is the red color Azorubine, which is added to the rice, sauce, and sweets. In this student research project, we intend to correlate the common eating habit to the biochemical studies of the effect of some dyes on our health through understanding the serum albumin- Azorubine dye conjugates. In addition, the antagonistic effect of calcium and magnesium ions in competing and protecting serum albumin from binding to the Azorubine dye was investigated. Furthermore, the use of several biochemical techniques in separation, characterization, and stoichiometric analysis of dye-protein binding were applied. Some of the specific techniques the student will use including spectrophotometry, membrane dialysis, and dynamic light scattering (DLS).
Formulation of vitamin D encapsulated argan oil nanoemulsion: Its potential anti-oxidant activity
Nanoemulsion were successfully made from a food proved surfactant and an endemic Argan oil which is known to have many benefit. Nanoemulsion were characterized by DLS and zeta potential and were found to be stable for 30 days. Vitamin D was successfully encapsulated in the nanoemulsion by two different techniques.
