Microstructure Tailoring of Laser Powder Bed Fused Nb521 Alloy Toward Strength‐Ductility Synergy

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Niobium‐based refractory alloys are promising candidates for high‐temperature aerospace structures, yet their limited ambient‐temperature ductility and poor processability remain major barriers to broader implementation. Here, Nb521 alloy was fabricated by laser powder bed fusion (LPBF), and the effects of processing conditions and subsequent ...

Analysis of S-duct's fluid-solid-thermal coupling characteristic considering creep effect

Hangkong gongcheng jinzhan
For the hypersonic vehicle whose inlet and combustion chamber are not on the same axis，the S-duct is an important component，and its main function is to turn the air flow. In order to study the influence of multi-field coupling effect of creep material on

Physics‐Aware AI‐Driven 4D Temperature Reconstruction With Enhanced Non‐Uniform Vertical Resolution in Near Space (20–80 km)

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Near‐space temperature is crucial for atmospheric dynamics and aerospace applications, yet data sets with refined vertical resolution remain scarce. We present the Atmospheric Spatio‐Temporal Reconstruction Network (AtmoST‐Net), which integrates high‐resolution SABER observations with dual‐source reanalysis, combining non‐uniform vertical ...

Effect of a Roughness Element on the Receptivity of a Hypersonic Boundary Layer over a Blunt Cone Due to Pulse Entropy Disturbance with a Single Frequency

Entropy, 2018
A high-order finite difference method was used to simulate the hypersonic flow field over a blunt cone with different height roughness elements. The unsteady flow field induced by pulse disturbances was analyzed and compared with that under continuous ...

Multiscale Architecture and Mechanics of the Cell Nucleus: Implications for Disease, Bioengineering and Nanomedicine

Advanced Science, Volume 13, Issue 37, 3 July 2026.
Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

Tunable High‐Performance Metamaterial Filters Based on Novel SRR Architectures

Advanced Science, Volume 13, Issue 42, 28 July 2026.
Based on two novel SRR configurations and two independent SRR integration approaches, four tunable bandpass metamaterial filters were fabricated with an ultra‐thin ceramic substrate. Among them, SM‐2 achieves over 97% electromagnetic wave transmittance, with a minimal 1.15% deviation in its resonant frequency prediction, making them promising ...
