  Artificial Intelligence–Assisted Reduced-Order Modeling and Stability Control in Granular Couette Flow

  By Lakshmi. N. Sridhar

  Abstract: This study develops a reduced-order and stability-aware modeling framework for dense granular Couette flow by integrating continuum mechanics, bifurcation analysis, and data-driven stability estimation. Starting from coupled governing equations for momentum, granular temperature, and microstructural evolution, the system is nondimensionalized and reduced using a Galerkin projection consistent with shear-driven boundary conditions. This yields a low-dimensional nonlinear dynamical system that preserves the essential coupling between velocity, fluctuation energy, and structural relaxation. …

  Framework-Based Optimization of Catalysis Efficiency through Reaction Pathway Engineering

  By Ann Mati*, Chinaza F. Nwachukwu

  Abstract: The rational design of heterogeneous catalysts through framework-based approaches has emerged as a transformative strategy for controlling reaction pathways and enhancing catalytic efficiency. This paper examines recent advances in the optimization of catalytic performance through engineered frameworks, including metal-organic frameworks (MOFs), zeolites, and related porous materials. By integrating computational methods with experimental validation, researchers have achieved unprecedented control overactive site architecture, reactant confinement, and elementary reaction steps. This work reviews …

  Design, Synthesis, and in vitro Evaluation of Novel Benz/Imidazole-2-acetonitrile Derivatives as Antibacterial and Antifungal Agents

  By Hanan Faleh Mohsein

  Abstract: Benzimidazole is a pharmaceutically important compound. In this research, we were able to prepare several heterocyclic derivatives from it by first preparing a new azo derivative ZH through a reaction of 3-aminoacetophenone with benzimidazole-2-acetonitrile. This azo derivative was then introduced via a condensation reaction with aromatic amine derivatives, resulting in the preparation of two Schiff base derivatives Z1 and Z2. From these bases, six and seven membered heterocyclic derivatives were …

  Sustainable Carbon Materials for Catalysis, Energy Conversion, and Environmental Remediation

  By Tharun KP, Indra Neel Pulidindi

  Abstract: Among the most ancient and adaptable materials used by humans, carbon finds use in a wide range of industries, including electronics, energy production, medicine, water purification, air filtration, and catalysis. Among them, activated carbon's highly developed microporous structure, remarkably large specific surface area, and adjustable surface functions have drawn a great deal of attention from both science and industry. Activated carbon materials have been widely used as molecular sieves, adsorbents …

  A Review of Modifications of Cement Slurry Formulations for Carbon Dioxide Storage

  By Yetunde Aladeitan, Okhiria D. Udebhulu

  Abstract: Climate action, which includes activities aimed at mitigating climate change or reducing its adverse impacts, is the thirteenth goal of the 2030 SDGs (Sustainable Development Goals). Tthe successful commercial deployment of CCS technology would heavily rely on the integrity of the cement sheath used to complete the wellbores at the CO₂ storage sites. It has been established that the cement sheath made from conventional ordinary Portland cement (OPC) is not …

  Study on Single-Slope Solar Still for Experimental and Data-Driven Analysis for Improving Productivity with Different Basin Materials.

  By Naveen Kumar, Happy Srivastava, R. Prasad

  Abstract: This study investigates the single-slope solar still under the diurnal variation of water temperature and distillate yield under identical operating conditions. Experimental analysis was conducted to evaluate the performance enhancement through the incorporation of natural basin materials, namely hemp and sand. The water distillation process is focused on improving potable water productivity and thermal behaviour. The inclusion of hemp and sand in the basin leads to noticeable differences in productivity …

  Effect of Microbial Species and Inoculum Dosage on Anaerobic Digestion

  By C.P. Ukpaka, J.A.G. Azuatalam

  Abstract: This work aims at studying the effect of microbial species and inoculum dosage on anaerobic digestion of food waste using cattle rumen content as inoculum. Four different batch runs were carried out with different percentage inoculations which were (control sample), 25% dosage, 50% dosage and 75% dosage. To have both logical and scientific explanation why the inoculated samples had better performance than the control sample, microbial identification was carried out …
