This study systematically investigates how ultrasonic atomization parameters influence the morphology and composition of Sn-58Bi solder powder, demonstrating that optimized conditions yield high-quality powder capable of forming strong solder joints with a maximum shear strength of 44.7 MPa in ultrasonic-assisted soldering applications.
This study presents a fluorine-free, magnetically recoverable BiFeO₃@g-C₃N₄/TEOS-PDMS coated cotton fabric that achieves highly efficient gravity-driven oil-water separation and Z-scheme photocatalytic dye degradation through a durable, eco-friendly hybrid coating.
This paper presents a novel near-infrared fluorescent probe, N-Bu-DCIB-2DNP, which utilizes a cascade thiolysis strategy to rapidly and sensitively detect hydrogen sulfide with dual emission signals, demonstrating successful application in visual test strips for spoiled food and real water samples.
This study demonstrates that incorporating waste eggshells as a dual-function CO₂ adsorbent and catalyst in municipal solid waste gasification significantly reduces CO₂ emissions while enhancing hydrogen and carbon monoxide yields, ultimately improving overall process efficiency through effective calcium-based carbon capture.
This study demonstrates that co-doping spark plasma sintered CoCrMn medium-entropy alloys with silicon and vanadium, particularly at a 2.5Si-2.5V composition, significantly enhances microhardness, densification, wear resistance, and corrosion performance by promoting a dendritic microstructure and the formation of a protective passive film.
This study presents a reversible, pressure-swing acidification process using SO₂ to achieve closed-loop, total separation of olivine into high-purity iron and magnesium oxides while recycling reagents and significantly reducing energy costs compared to existing methods.
This study demonstrates that Cu and Zn doping of NiTiO₃ nanoparticles yield divergent bandgap responses due to their distinct electronic configurations, where Cu²⁺ introduces impurity states that significantly narrow the bandgap and enhance visible-light photocatalytic activity, while Zn²⁺ has a negligible effect.
This study demonstrates that MnCo2O4 spinel nanostructures anchored on multi-walled carbon nanotubes, synthesized via hydrothermal-assisted calcination, deliver exceptional pseudocapacitive performance with high specific capacitance, superior rate capability, and outstanding cycling stability, making them a promising electrode material for next-generation high-performance supercapacitors.
This study employs a multidimensional approach combining Taguchi optimization, kinetic and thermodynamic modeling, and life cycle assessment to evaluate n-Hexane, n-Heptane, and Ethanol for spent coffee grounds oil extraction, revealing n-Hexane as the most efficient solvent while identifying Ethanol as the most environmentally sustainable option for biodiesel production.
This study presents an autonomous, multi-stimuli-responsive bilayer hydrogel actuator that, when coupled with a newly developed NaOH–Sultone pH-clock, achieves programmable bidirectional mechanical motion and synchronized fluorescence modulation without external intervention.
