In this work, we present an efficient strategy for the straightforward synthesis of functionalized 1,6-dihydropyridine derivatives a three-component reaction of 3-vinylchromones, aromatic aldehydes, and ammonium acetate. A tandem procedure including NH aldimine formation/Michael-type addition/opening of the pyrone ring/isomerization/6π-electrocyclization/[1,5]-H shift allows rapid access to a series of dihydropyridines bearing an -hydroxybenzoyl and a benzoyl scaffold in good yields. Readily available precursors, simple heating conditions, and operational simplicity are some highlighted advantages of this transformation.

Enhancing oil recovery in sandstone reservoirs, particularly through smart water flooding, is an appealing area of research that has been thoroughly documented. However, few studies have examined the formation of water-in-heavy oil emulsion because of the incompatibility between the injected water-folded ions, clay particles, and heavy fraction in the oil phase. In this study, we investigated the synergistic roles of asphaltene and clay in the smart water flooding process using a novel experimental approach.

Assessing the impact of climate change on water-related ecosystem services (ES) in Protected Areas (PAs) is essential for developing soil and water conservation strategies that promote sustainability and restore ES. However, the application of ES research in Protected Area (PA) management remains ambiguous and has notable shortcomings. This study primarily aimed to assess the SDR-InVEST (Sediment Delivery Ratio-Integrated Valuation of Ecosystem Services and Tradeoffs) model for estimating ES, including soil loss, sediment export, and sediment retention, under various climate change scenarios from 1997 to 2100 in the data-scarce region of the Bagh-e-Shadi Forest PA.

A fault tolerant CSA in QCA technology for IoT devices.

Sci Rep

January 2025

Department of Computer Engineering, Faculty of Engineering, Bu-Ali Sina University, Hamedan, Iran.

According to recent research, with the ever-increasing use of Internet of Things (IoT) devices, there has arisen an ever-growing need for high-performance yet low-power circuits that can efficiently process information. Quantum-dot Cellular Automata (QCA) has emerged as a promising alternative to conventional complementary metal-oxide-semiconductor (CMOS) technology due to its great potential in digital design at nanoscale levels on account of very low power consumption and very high processing speed. However, QCA circuits are inherently prone to faults due to variations in manufacturing processes and due to the influence of environmental factors.
