This study elucidates the mechanistic drivers of chloride-induced stress corrosion cracking (CISCC) and internal pitting in austenitic stainless steel by utilizing advanced electron microscopy to reveal how grain-scale plasticity, slip system availability, and localized corrosion collectively dictate crack propagation paths and the formation of internal pits.
This paper presents a combined experimental and modeling approach using femtosecond laser-driven carbon nanotube emitters and an augmented electric-field integral equation method to characterize ultrafast electron pulses, revealing that pulse widths can be smaller than laser pulses and optimized by increasing emitter density for advanced terahertz and imaging applications.
This study derives exact analytical solutions for the unsteady magnetohydrodynamic flow and heat transfer of a Casson hybrid nanofluid containing magnetite and cobalt ferrite particles in a vertical porous channel, utilizing the Caputo-Fabrizio fractional integral to model thermal memory and demonstrating how fractional parameters, nanoparticle concentration, and magnetic fields significantly influence the fluid's thermal and hydrodynamic behavior.
This paper introduces a single-station diagnostic method using the Jones–Kusunose gap derived from time-resolved 3D particle tracking velocimetry to distinguish the specific physical mechanisms of wingtip vortex control devices—such as span extension, core unwinding, or core intensification—that remain indistinguishable through conventional integral force measurements alone.
This paper presents a novel self-consistent field (SCF) method that prevents variational collapse in metastable anions by removing non-physical pseudo-continuum states from the Fock matrix and employing a complex absorbing potential, thereby enabling stable anionic calculations and efficient post-SCF correlation treatments with reduced computational cost.
This study employs a time-dependent Ginzburg-Landau approach to investigate how introducing symmetric subdivisions into a superconducting nano-bridge influences Abrikosov and kinematic vortex dynamics, critical currents, and Shapiro steps, ultimately proposing a method for the organized control of fluxoids in mesoscale samples.
This work proposes and experimentally demonstrates a robust topological plasmonic cavity strategy that converts symmetry-protected bound states in the continuum into quasi-BICs to achieve deterministic, directional upconversion emission from individual nanocrystals with enhanced light-matter interactions and structural resilience.
This paper demonstrates that integrating 2D materials like molybdenum disulfide (MoS2) onto metal-dielectric photonic crystals significantly enhances the sensitivity and detection limits of Bloch-like surface wave-based sensors for physiological glucose monitoring.
This study demonstrates that combining a low-temperature amorphous TiO₂ electron transport layer with Mg²⁺ and Ba²⁺ cationic doping in perovskite absorbers significantly enhances HTL-free solar cell performance by reducing bulk defect density, engineering the bandgap, and optimizing key photovoltaic parameters like short-circuit current and open-circuit voltage.
This study investigates the kinetic mechanisms of Hot-Wire Chemical Vapor Deposition for silicon nitride films, revealing that a 32A hot-wire current optimizes the balance between optical properties and surface quality, while a 200°C substrate temperature maximizes refractive index and passivation performance, with higher temperatures inducing thermal stress that degrades film density and optical properties.
