This study demonstrates that incorporating a Ti foil as an intermediate layer successfully joins TiAl45XD and GH4169 alloys, revealing a four-layer microstructure where shear fractures predominantly initiate in diffusion layers II and III due to the mechanical property disparities between phases like hard γ-Ni and soft Ti₃Al.
This study reports the first naked-eye visualization of light helicity in luminescent films by developing a hybrid system of chiral Eu(III) complexes and an achiral dye that converts circularly polarized luminescence into distinguishable emission colors for advanced security applications.
This study demonstrates that cost-effective spray-pyrolysis of aqueous silver-tin-sulfide solutions followed by nitrogen annealing yields Ag₈SnS₆-based thin films with tunable n- and p-type conductivity, improved crystallinity, and enhanced optoelectronic properties suitable for large-scale applications.
This study demonstrates the successful synthesis of Ti/SiO2 composite powder via powder metallurgy, confirming through multi-technique characterization that high-energy mechanical mixing and vacuum sintering facilitate chemical interfacial bonding while preserving the nanoscale α-quartz structure and thermodynamic stability without forming secondary phases.
This study demonstrates that TiO₂ photocatalysis is the most efficient advanced oxidation process for ciprofloxacin remediation, offering superior degradation kinetics and energy efficiency compared to photolysis and high-voltage electrical discharges, while highlighting that short-duration treatments can transiently increase ecotoxicity due to the formation of more toxic intermediate byproducts.
This study demonstrates that ohmic fermentation effectively differentiates the volatile fingerprints of roasted Arabica and Robusta coffees from four Indonesian origins by generating distinct, origin-specific chemical profiles dominated by classes such as furans, ketones, and pyrazines.
By integrating operando spectroscopies, density functional theory, and spectro-kinetic analysis, this study identifies monomeric, high-spin Fe species in the 6-membered rings of Fe-CHA zeolites as the active sites that enable continuous N2O-assisted methane hydroxylation to methanol through a mechanism involving kinetically relevant site formation and C-H bond cleavage.
This paper proposes a modified Scarf-type interaction potential that, when solved via the parametric Nikiforov-Uvarov method, accurately predicts vibrational energy eigenvalues and chemical equilibrium constants for selected diatomic molecules, demonstrating strong agreement with experimental and reference data.
This paper introduces a transferable diamond tape strategy that decouples diamond growth from metal substrates by growing polycrystalline diamond on a releasable TiO₂ nanorod-engineered silicon template and attaching it to Ti6Al4V via a TiO₂ sol-gel adhesive, thereby creating a hierarchical, wear- and corrosion-resistant protective layer that reduces wear rates by four orders of magnitude and significantly lowers corrosion current density.
This DFT study challenges the hypothesis of a zwitterionic intermediate in the (3+2) cycloaddition between 2-diphenylphosphinoyl-2-methyl-3,4-dihydro-2H-pyrrole N-oxide and di-t-butyl selenoketone by demonstrating that while a two-step pathway is possible, it is less favorable than the kinetically preferred route that explains the observed regio- and stereoselectivity.
