Stability-Indicating Rp-Hplc Development and Validation for the Estimation of Lercanidipine Hydrochloride Content in Tablet Dosage Form
Abstract: A sensitive, stability-revealing, and easy reverse-phase high-performance liquid chromatographic (RP-HPLC) technique was developed and rationalized to be in a position to determine Lercanidipine hydrochloride in ingested dosing preparations. It was separated by chromatography on a C 18 column using a mobile phase containing 10 mM potassium dihydrogen phosphate buffer and methanol (20:80, v/v; pH 4.0) at a flow rate of 1.0 mL/min and UV detected at 258 nm. The retention …

Optimization of Fly Ash and Granulated Blast Furnace Slag (FA-GBFS) Mixes for Flexible Pavements
Abstract: This study investigates the compaction, strength, and permeability characteristics of fly ash (FA) stabilized with granulated blast furnace slag (GBFS) to determine the optimal mix proportions for geotechnical applications. Standard Proctor compaction, unconfined compressive strength (UCS), California Bearing Ratio (CBR), and permeability tests were conducted on FA-GBFS mixtures, with GBFS content varying from 10 to 50% by dry weight. The results indicate that increasing GBFS content enhances the maximum dry …

Mechanical & Tribological Characterization of Al2024-Alumina-Graphite Reinforced Monolithic and Hybrid Composites
Abstract: This work investigates the mechanical characteristics of Al2024-Al2O3-Graphite reinforced monolithic and hybrid composites fabricated by the stir casting method. Exploratory work involved the fabrication of monolithic composites with varying Al2O3 contents (5-8 wt%) and hybrid composites with the ratios of Al2O3 (2-6 wt%) and Graphite (1-3 wt%) in matrix Al2024. For improving their dispersion, preheated reinforcement particles were introduced in matrix alloy at controlled stirring rates. A homogeneous particle distribution …

Chemiluminescence: Recent Developments and Photochemical Applications in Analytical Chemistry
Abstract: Chemiluminescence (CL) is the observable production of electromagnetic radiation from a chemical reaction, typically in the form of ultraviolet, visible, or infrared light. According to subjective yield, CL has either been directly emitted from electronically excited intermediate products, or it has been supported by another molecule to emit CL. Since the 1950s, CL has been supported as a valid analytical tool, with the descriptive issued scope being limited to content …

Optimizing Mechanical and Durability Properties of Eco-Friendly Composite Materials Using Recycled Fillers and ML Techniques
Abstract: The increasing demand for sustainable construction materials has intensified the exploration of recycled fillers as partial or full replacements for natural aggregates in composite materials. This study investigates the mechanical and durability performance of polymer matrix composites incorporating processed recycled fillers derived from construction and demolition (C&D) waste. Three distinct processing methods were employed to prepare the recycled fillers: untreated (URF), single processed (SPRF), and double processed (DPRF), with replacement …

Investigating the Mechanical Properties and Microstructure of AA 7074 Composites with Silicon Nitride Reinforcement
Abstract: This study investigates the mechanical and microstructural properties of AA 7074 aluminium alloy reinforced with 1%, 3%, and 5% by weight of silicon nitride (Si₃N₄), fabricated via the stir casting method, intended for structural aerospace applications. A thorough series of mechanical tests—comprising tensile, compression, hardness, impact, flexural, and wear tests—was performed to assess the influence of differing reinforcing content. The composite containing 5 wt% Si₃N₄ (SN5) demonstrated the most pronounced …
