Enhanced electro-osmotic microfluidic mixing in an obstacle-embedded converging–diverging channel

This work presents an electro-osmotic micromixer that contains an obstacle-embedded converging-diverging channel for the purpose of enhancing fluid mixing at the microscale. Based on the finite element method, a two-dimensional transient model for Alternating current (AC) electro...

Fracture behavior of nano‐silica‐modified recycled aggregate concrete: Experimental evaluation and predictive modeling using work of fracture and size effect methods

Abstract This study investigates the fracture behavior of recycled aggregate concrete (RAC) modified with nano‐silica (NS), aiming to enhance the performance of sustainable concrete made with recycled materials. While recycled aggregates reduce environmental impacts, they comprom...

Artificial intelligence framework for predicting inclined magneto-bioconvective Ellis penta-hybrid nanofluid flow over a stretching cylinder with gyrotactic microorganisms: A Levenberg–Marquardt approach

This study aims to develop data-driven framework for predicting the magneto-bioconvective transport characteristics of an Ellis penta-hybrid nanofluid over a stretching boundary, with particular emphasis on rheological behavior, Brownian diffusion, thermophoresis, and gyrotactic...

Spent coffee grounds ash as a potential sustainable binder for mechanical and microstructural enhancement of alkali-activated mortars

The global generation of spent coffee grounds (SCG) poses serious environmental challenges, including landfill occupation and greenhouse gas emissions. Although SCG and its derivatives have been investigated in construction materials, the application of spent coffee grounds ash (...

Hybrid Cu/Zn-BDC@MA-BTCStructures as SynergisticFillers for High-Performance Mixed Matrix Gas Separation Membrane

Abstract Achieving an optimal balance between permeability and selectivity, along with enhancing CO2 separation performance, is a key challenge in the development of mixed-matrix membranes. In this study, a binary Cu2+/Zn2+ MOF based on the H2BDC ligand was employed due to the pr...

Exploring cybersecurity adaptation assessment criteria in the oil and gas industry

Cybersecurity is a pillar of Industry 4.0 that guarantees the safe and secure application of other pillars, such as Internet of Things (IoT), 3D printing, Simulation, and augmented/virtual reality. Nonetheless, cybersecurity management has been paid less attention in energy secto...

Water-Saving Attitudes in Residential Gardens: Exploring Climate Change Exposure, Risk Perception, Belief, and Environmental Efficacy

Abstract As climate change intensifies, understanding the psychological and contextual factors that shape water-saving attitudes in residential gardening is increasingly important, particularly in arid and semi-arid countries such as Iran. This study examines how climate-related...

The implementation of wide angle and UWB retrodirective linear Van Atta array

This paper presents the design, fabrication, and experimental validation of a broadband 1×16 Van Atta reflector array based on compact antipodal Vivaldi antennas. The proposed structure achieves wide azimuthal coverage in addition to ultra-wideband operation, ensuring stable retr...

Parametric hydrodynamic and acoustic performance analysis of toroidal propellers with emphasis on geometric variations and advanced design optimization

Toroidal propellers, defined by their continuous closed-loop blade topology, offer promising potential for marine propulsion but remain insufficiently characterized through systematic geometric parametrization. This paper presents a numerical and experimental study of toroidal pr...
