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

Rare‐Earth–Sulfur Surface Modification Enables SiC Ceramics for Low‐Frequency Electromagnetic Wave Absorption in Extreme Environments

Advanced Science, Volume 13, Issue 55, 5 October 2026.
By altering surface chemical bonds to prolong relaxation time and shift absorption to lower frequencies, SiC/rare earth–sulfur (RE─S, RE = La, Ce, Pr, Sm, Gd, Er) materials achieve excellent low‐frequency electromagnetic wave absorption under extreme conditions, offering a new direction for designing high‐performance SiC‐based absorbers.

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 ...

The importance of biodiversity components differs among wood‐based material Nature's contributions to people (NCP) in a tropical montane ecosystem

Oikos, Volume 2026, Issue 10, October 2026.
Biodiversity can influence forest productivity, but this does not necessarily translate into higher provision of wood‐based Nature's contributions to people (NCP), as only a subset of the wood produced is used for each NCP. Biodiversity–NCP relationships therefore require further assessment.

Core–Shell UHTCs as a Multiscale Design Paradigm for Extreme Environments

International Journal of Applied Ceramic Technology, Volume 23, Issue 5, October 2026.
ABSTRACT An integrated perspective on the performance of multiscale core–shell ultra‐high temperature ceramics (UHTCs) developed through a multiphase design strategy is here presented. The manuscript merges insights gained from studies on ZrB2 formulated and processed in the presence of a second transition metal compound based on W, Mo, or Ta ...
