The Molecular Structure of Chemical Compounds by using Quantitative Calculations in Chemistry
Abstract: Computational chemistry has its roots in the early attempts of theoretical physicists, beginning in 1928, to solve the Schrödinger equation using mechanical calculating machines. These calculations verified that the solutions of the Schrödinger equation quantitatively reproduced experimentally observed properties of simple systems such as the helium atom and the hydrogen molecule. These approximate solutions of larger systems and exact solutions of simple model problems allowed chemists and physicists to provide …

Guanidine as a Starting Material for Preparing a Scale Inhibitor
Abstract: Oilfield scale inhibition, which can obstruct fluid flow in pipelines, valves, and pumps during oil production and processing, is critical for preventing scale formation. Effective scale inhibitors (SIs) minimize downtime and enhance productivity by preventing the build-up of insoluble crystals in water systems. In oil processing, scale formation results from the precipitation of salts due to incompatible aqueous phases, leading to equipment blockage. Phosphonates are highly effective chelating agents for …

Improving the Mechanical and Interfacial Properties of Bhendi Fiber via Chemical Surface Treatments
Abstract: Because of its primary benefits—moderate strength and stiffness, low cost, and being a renewable, degradable, and ecologically friendly material—natural fibers are believed to have potential use as reinforcing agents in polymer composite materials. Due to their inherent hydrophilicity, they have a tendency to retain moisture, which can impair or soften the fibers' adhesion to the surrounding matrix. This can have an impact on the performance of composite materials used in …
