6+ hour, 15+ min ago   (469+ words) Carbon nanoparticles (CNPs) have attracted considerable attention for biomedical applications owing to their excellent biocompatibility, tunable optical properties, and low toxicity. In this study, we report a simple, rapid, and cost-effective one-pot bottom-up synthesis of fluorescent carbon nanoparticles using propanoic…...

18+ hour, 53+ min ago   (352+ words) This comprehensive review systematically examines the fundamental and contemporary concepts underlying the Toms effect—the phenomenon of turbulent drag reduction (DR) induced by the addition of minute concentrations of high-molecular-weight linear polymers to turbulent flows. The evolution of scientific understanding…...

1+ day, 16+ hour ago   (430+ words) Accurate remaining useful life (RUL) prediction of lithium-ion batteries is critical for reliable operation of the system. The performance evolution of lithium-ion batteries shows long-range dependence and capacity regeneration. However, existing performance evolution models fail to properly consider the joint…...

2+ day, 17+ hour ago   (383+ words) This work presents an electrochemical, kinetic, and morphological study of iron electrodeposition on a glassy carbon electrode from an ammonium chloride-based electrolyte containing 0.01 M FeCl2 and 0.1 M NH4Cl at pH 6.0. Thermodynamic analysis identified [Fe(H2O)6]2+ as the predominant Fe(II) species under the investigated…...

3+ day, 18+ hour ago   (492+ words) Miniaturized spatial electric field sensors often exhibit insufficient front-end charge coupling because of their limited sensing area. To address this material-level bottleneck, KH550-functionalized graphene composite films were developed as candidate electrode materials for spatial electric-field sensing. Single-layer and multilayer graphene…...

4+ day, 14+ hour ago   (498+ words) Macadamia husk, a major by-product of the macadamia industry, represents an underutilised source of phenolic compounds with significant potential for value-added applications. This study aimed to investigate the effects of extraction methods (conventional solvent extraction, accelerated solvent extraction and ultrasonic…...

4+ day, 18+ hour ago   (394+ words) Accurate prediction of moisture transfer during drying processes remains challenging. In the present study, a progressive numerical framework was developed to investigate moisture diffusion in ethanol-pretreated beetroot by systematically incorporating increasing levels of physical complexity into Fick’s second law of…...

5+ day, 12+ hour ago   (541+ words) Vibration-based piezoelectric energy harvesting provides a potential power source for low-consumption devices; however, its prediction requires a consistent representation of localized structural properties and experimentally identified modal behavior. This study presents the structural and modal qualification of an analytical electromechanical…...

5+ day, 12+ hour ago   (445+ words) The increasing accumulation of pharmaceutical residues in water environments poses serious threats concerning environmental safety and public health, mainly due to their tenacity, continuous bio-activity, and resistance to traditional wastewater treatment processing. Although many nano-bio/chemosensor systems have been reported…...

5+ day, 16+ hour ago   (503+ words) Metal foams and nanofluids are recognized as attractive and effective heat transfer enhancement methods. This study numerically investigates forced convection heat transfer and second-law thermodynamic behavior of water and a 0.02% Cu–MXene/water hybrid nanofluid flowing through a tube partially…...
