This study evaluates four low-GWP HFO/ionic-liquid working pairs in single-effect and compression-assisted absorption refrigeration cycles, identifying R1234ze(E)/[C4mim][DCA] as the optimal pair and demonstrating that the compression-assisted configuration significantly enhances performance and operating range for low-grade heat applications.
This study employs first-principles density functional theory calculations to investigate the structural, electronic, optical, magnetic, and thermoelectric properties of Ba₂HoXO₆ (X = Rh, Ru, Os) double perovskites, revealing their half-metallic nature and potential for eco-friendly spintronic and renewable energy applications.
This study investigates the mixed convection Darcy-Forchheimer MHD flow and radiative heat transfer of a copper-based water-ethylene glycol hybrid nanofluid over a permeable stretching surface using the Differential Transform Method to analyze how various physical parameters, including thermal radiation, Joule heating, and boundary conditions, influence velocity and temperature profiles.
This review elucidates the microstructural origins and fracture mechanisms of local embrittlement in the heat-affected zones of welded 9Ni steel at cryogenic temperatures, emphasizing the critical role of local microstructure over average properties and proposing targeted mitigation strategies to shift assessment from average-property qualification to local risk identification.
This study employs density functional theory with the GGA-PBE functional and the quasi-harmonic Debye model to comprehensively investigate the structural, electronic, thermophysical, and mechanical properties of cubic LaTiO₃, confirming its metallic nature and validating the results against existing experimental and theoretical data across a wide range of temperatures and pressures.
This study employs an integrated physics-based ETAS framework to analyze 14 years of reservoir-induced seismicity at Vietnam's Song Tranh 2, revealing that while natural tectonic background dominates, persistent activity is driven by fault interactions and rapid fluid transport through anisotropic basement faults that lower frictional thresholds to reactivate stable structures.
This study demonstrates that accurate offshore hypocenter location using submarine DAS in the Nankai Trough can be achieved by leveraging prominent P-to-S converted waves as proxies for faint direct P waves, provided that correct phase identification, phase-specific station corrections, and reliable 3D velocity structures are employed.
This study demonstrates that circularly polarized below-gap mid-infrared pulses can efficiently generate coherent magnons in the antiferromagnet Sr2IrO4 via a nonresonant one-photon–two-magnon coupling mechanism, offering a highly effective pathway for ultrafast spin control.
This study demonstrates that a scalable, eco-friendly acidic vapor-phase etching process effectively creates porous silicon layers on multicrystalline silicon solar cells, significantly reducing reflectivity and recombination losses to boost power conversion efficiency from 8.80% to 11.50% while eliminating liquid chemical waste.
This study demonstrates that low-order harmonics in wide-bandgap dielectrics arise from a strongly non-perturbative intraband current rather than a gas-phase-like injection channel, enabling highly efficient, half-cycle switching of harmonic signals with nearly 100-fold contrast.
