Radiation‐Resistant Aluminum Alloy for Space Missions in the Extreme Environment of the Solar System
Advanced Materials, EarlyView.A novel ultrafine‐grained aluminum crossover alloy exhibits unprecedented radiation resistance and mechanical stability under extreme irradiation doses up to 100 dpa. The exceptional resilience arises from thermodynamically stable T‐phase precipitates, enabling lightweight structural materials for next‐generation spacecraft and extraterrestrial ...

Advanced Materials, EarlyView.Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Advanced Materials, EarlyView.The graphic illustrates the design of a hybrid bilayer composed of a liquid crystal hydrogel (LCH) and a liquid crystal network (LCN). The figure highlights the magnetic alignment of the chromonic hydrogel and the thermal‐responsive actuation of the LCN along with the LCH when both layers are aligned or misaligned, enabling programmable, light‐driven ...

Influence of Jumboizing on Propulsive Performance
JOURNAL OF THE MARINE ENGINEERING SOCIETY IN JAPAN, 1999 This paper is concerned with the influence of hull elongation on engine and propulsive performance. Though propulsive performance is known to relate closely to the principle dimensions of a ship, it is not yet clear how ship length can influence the performance of CPP (controllable pitch propeller) ship and FPP (fixed pitch propeller) ship, both of ...
