Experimental and computational approach on the corrosion inhibition properties of two newly pyrazole derivatives on carbon steel in acid medium.
Sci Rep

LCEA Laboratory, Faculty of Sciences, Mohammed Premier University, Oujda, Morocco.
In the current investigation, the efficiency inhibition of two newly synthesized bi-pyrazole derivatives, namely 2,3-bis[(bis((1 H-pyrazol-1-yl) methyl) amino)] pyridine (Tetra-Pz-Ortho) and 1,4-bis[(bis((1 H-pyrazol-1-yl) methyl) amino)] benzene (Tetra-Pz-Para) for corrosion of carbon steel (C&S) in 1 M HCl medium was evaluated. A Comparative study of inhibitor effect of Tetra-Pz-Ortho and Tetra-Pz-Para was conducted first using weight loss method and EIS (Electrochemical Impedance Spectroscopy) and PDP (Potentiodynamic Polarisation) techniques. Tetra-Pz-Ortho and Tetra-Pz-Para had a maximum inhibition efficacy of 97.

The adoption of carbon capture, utilization, and storage (CCUS) technology is increasingly prevalent, driven by the global initiative to conserve energy and reduce emissions. Nevertheless, CCUS has the potential to induce corrosion in equipment, particularly in high-pressure environments containing carbon dioxide (CO). Therefore, anti-corrosion protection is necessary for the metal utilized for CO production and storage equipment.

Purpose: To assess the effect of anterior chamber depth on corneal endothelium using specular microscopy following uneventful phacoemulsification among cataract patients with different axial lengths.
Methods: The study was conducted in a quasi-experimental design including 300 eyes of 300 patients with grade three age-related nuclear cataract distributed equally based on their axial length into three equal groups. All eyes had grade three nuclear cataract.
Physical Isolation Strategy in Multi-Layer Self-Nanoemulsifying Pellets: Improving Dissolution and Drug Loading Efficiency of Ramipril.

Background And Purpose: Liquid self-nanoemulsifying drug delivery systems (SNEDDS) face challenges related to stability, handling, and storage. In particular, lipophilic and unstable drugs, such as ramipril (RMP) and thymoquinone (THQ), face challenges in oral administration due to poor aqueous solubility and chemical instability. This study aimed to develop and optimize multi-layer self-nanoemulsifying pellets (ML-SNEP) to enhance the stability and dissolution of ramipril (RMP) and thymoquinone (THQ).

This study focused on developing biodegradable packaging films based on starch as an alternative to non-biodegradable such as petroleum-derived synthetic polymers. To improve its physicochemical properties, potato starch was chemically modified through phosphorylation. Starch phosphorylation was carried out using cyclic 1,3-propanediol phosphoryl chloride (CPPC), produced phosphorylated starch (PS), and analyzed using Fourier transform infrared (FT-IR), X-ray diffraction (XRD), Nuclear magnetic resonance (NMR), and Thermogravimetric analysis (TGA).
