Mud Acid Effect on Fines Migration Problem Using a Newly Developed Al/Zr-Based Clay Stabilizer (A): Mitigation Can Happen
Abstract: Sandstone reservoirs exhibit severe fines migration problems subsequent to conventional mud acid (HCl: HF) treatments. The acid treatment proved to be effective for a relatively short period of time, with a sudden production decline owing to either that mud acid spent rapidly in close proximity to the wellbore, causing clays to migrate into the acidized area and re-plug the formation; or that the mud acid system actually weakens the structure …

Synthesis of Isoamyl Acetate (Banana oil) Using Fly Ash Supported Nano Crystalline Solid Acid Catalyst
Abstract: A novel fly ash supported solid acid catalyst (HClO4/FA) has been synthesized by using F-type fly ash and HClO4 as precursor. The variation of surface and physicochemical properties of the fly ash by activation methods resulted in improved acidity and therefore, catalytic activity for acid catalyzed esterification reactions. The HClO4/FA catalyst was characterized by XRF, XRD, FT-IR, SEM and BET surface area. The catalytic performance of HClO4/FA catalyst was evaluated …

A Systematic Review on Peptic Ulcer Disease and its Pharmacological Treatment
Abstract: A chronic gastrointestinal condition known as Peptic Ulcer Disease (PUD) is typified by the formation of ulcers or mucosal erosions in the proximal duodenum and stomach. In the pathophysiology of PUD, the equilibrium between defensive processes like mucus and bicarbonate secretion, mucosal blood flow, and prostaglandin production, and aggressive factors such stomach acid secretion, pepsin activity, and Helicobacter pylori infection, is upset. Although stress and food have historically been blamed, …

Structural Modification of Sugarcane Bagasse using Alkaline, Acid, and Bleaching Pretreatments for Enhanced Yield of Poly (1→4)-β-D-glucopyranose (Cellulose) and Hemicellulose for Utilization as Biocomposites
Abstract: Sugarcane bagasse, a lignocellulosic byproduct generated in substantial quantities by the sugar industry, represents a promising feedstock for the sustainable production of enzymes and bio-based chemicals. Its high (1→4)-β-D-glucopyranose (cellulose) content, abundant availability, and low cost make it an ideal candidate for bioconversion processes. However, the inherent recalcitrance of bagasse, primarily due to its lignin-rich matrix, necessitates effective pretreatment strategies to enhance enzymatic digestibility. This study presents a comparative investigation …
