Clarification of creep damage condition and rupture time prediction method for round notch bar specimens on Modified 9Cr-1Mo Steel under creep loading

Nihon Kikai Gakkai ronbunshu, 2019
Creep damage preferentially extends at a stress concentration portion in components such as steam turbines and boilers. Therefore, in order to maintain reliable operation of these components, it is necessary to clarify the relationship between the creep ...

A Super‐Adhesive Air Filter With Capillarity‐Mediated Spontaneous Particle Absorption via Dynamic Bond Exchange

Advanced Materials, EarlyView.
We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...
