Nano-eggshell/B(III)as a highly efficient heterogeneous catalyst for the synthesis of 1,3-oxazines in aqueous media, along with DFT simulations

In the present study, a convenient and greener synthesis of a series of naphtho[1,2- e ][1,3]oxazines was accomplished via three-component one-pot cyclocondensation between β -naphthol, formaldehyde, and various amines using nano-eggshell/B(III) as a natural catalyst in aqueous m...

Digital capabilities, global value chains, and sustainability: A bibliometric-content review of converging literatures and governance complementarities

Research on digital capabilities, including Industry 4.0 technologies, increasingly intersects with debates on sustainability and global value chains (GVCs), yet the evidence base remains uneven. This bibliometric-content review maps a 199-record broad-convergence corpus linking...

Scenario planning for Mashhad’s smart city: an ICT-driven future

Uncertainties and discontinuous probable events of the age of communication technology have penetrated into various aspects of human life and are seeking a new face for the spatial organization of future smart cities. This article systematically explores the possible futures, lea...

Multivariate predictive modeling of photothermal response of indocyanine green loaded graphene oxide under continuous and pulsed laser irradiation

The integration of photothermal therapy (PTT) into a single nanoplatform is a promising approach for precise cancer treatment; however, achieving predictable and optimized thermal doses remains a key challenge. While previous studies have explored graphene oxide (GO) and indocyan...

Analysis and optimization of process parameters affecting core-spun ring yarn properties using a soft computing-based approach

This study presents a soft computing-based framework for the analysis, modeling, and optimization of cotton/polyester core-spun yarn properties produced on a ring spinning system. The effects of pre-tension, core multi-filament linear density, twist level, and spindle speed on ya...

Reconfiguration of active medium- and low-voltage distribution networks based on multi-agent systems and mutual support capacity

Reducing power losses and preventing voltage instability remain key concerns in electrical distribution networks (DNs). These challenges are often addressed through reconfiguration of the network and the integration of distributed generation (DG) resources. In this study, a multi...

Development and psychometric validation of substance abuse prevention questionnaire based on the multi-theory model: construct validity and reliability

Substance abuse is one of the major social challenges worldwide. To address this issue, health promotion specialists are striving to overcome the limitations of existing health education models in promoting unhealthy behaviors. The relatively new Multi-Theory Model (MTM) has been...

Source identification and health risk assessment of potentially toxic elements in groundwater

This study presents an integrated assessment of potentially toxic elements (PTEs), pollution status, ecological risk, human health risk, spatial distribution, and source apportionment in groundwater from the Birjand aquifer, eastern Iran. Twenty-eight groundwater samples were col...
