Wire‐Laser‐Directed Energy Deposition of Ti‐6Al‐4V Alloy Under Vacuum: Effect of Substrate Preheating on the Refinement of Prior‐β Grain Structure

Advanced Engineering Materials, EarlyView.
Microstructural evolution of Laser beam Direct Energy Deposition (DED‐LB)/Ti64, showing changes in microstructure after employing a preheated build platform, as evaluated by both optical microscopy and scanning electron microscopy/electron backscatter diffraction (SEM/EBSD), highlighting changes in grain morphology, the formation of equiaxed grains ...

Field and lab conditions alter microbial enzyme and biomass dynamics driving decomposition of the same leaf litter

Frontiers in Microbiology, 2013
Fluctuations in climate and edaphic factors influence field decomposition rates and preclude a complete understanding of how microbial communities respond to plant litter quality. In contrast, laboratory microcosms isolate the intrinsic effects of litter

Enhanced Oxidation and Thermal Shock Resistance of N‐type Mg2Si0.89(Sn0.1,Sb0.01) Thermoelectric Material via Cr0.9Si0.1 Coating

Advanced Engineering Materials, EarlyView.
Cr0.9Si0.1 protective coatings are developed to enhance the thermal‐shock and oxidation resistance of Mg2Si0.89(Sn0.1,Sb0.01) thermoelectric (TE) materials. The coating forms a dense and adherent barrier that suppresses oxygen diffusion and mitigates mechanical degradation during cyclic oxidation, demonstrating its potential to improve the long‐term ...

Efficient and Scalable Radiative Cooling for Photovoltaics Using Solution‐Processable and Solar‐Transparent Mesoporous Nanoparticles

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 ...

Stabilized Intermediate Phase Via Pseudo‐Halide Anions Toward Highly Efficient and Light‐Soaking Stable Perovskite Solar Cells

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.

A decomposition of continuity

Acta Mathematica Hungarica, 1996
The authors define a subset \(S\) of a topological space \(X\) to be an \(\alpha^*\)-set if \(\text{int} S\) is regular open. A \(C\)-set is the intersection of an open set and an \(\alpha^*\)-set. A function between two spaces is called \(C\)-continuous if the inverse image of each open set is a \(C\)-set.
