Direct Natural and Artificial Aging of Aluminum Alloy AlSi10Mg After Laser Powder‐Bed Fusion
Advanced Engineering Materials, EarlyView.Laser powder‐bed fusion of metals aluminum alloy AlSi10Mg has been directly aged. Artificial aging after natural aging is considered. The hardening potential is high for the top part of the samples as well as after short natural aging. The hardening potential is substantially reduced for the bottom part of the samples, as well as after natural aging of

Advanced Functional Materials, EarlyView.Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...

Optimizing integrated luminosity of future hadron colliders
Physical Review Special Topics. Accelerators and Beams, 2015 The integrated luminosity, a key figure of merit for any particle-physics collider, is closely linked to the peak luminosity and to the beam lifetime. The instantaneous peak luminosity of a collider is constrained by a number of boundary conditions, such

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.This study reveals that higher shell S coordination can effectively modulate the spin state of FeN4 site via long‐range electronic interactions, giving rise to the oriented generation of singlet oxygen from peroxymonosulfate activation. Abstract Precise manipulation of coordination structure of single‐atom sites and establishment of schematic ...

Achieving Large and Anisotropic Spin‐Mediated Thermal Transport in Textured Quantum Magnets
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.An advanced solvent‐cast cold pressing method is developed to synthesize highly textured quantum magnets. By aligning spin chains in Ca2CuO3 perpendicular to the pressing direction, a spin‐mediated thermal conductivity of 10 ± 1 W m⁻¹ K⁻¹ is achieved, the highest reported for polycrystalline quantum materials.
