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...
