Vitrimers are a novel generation of spacecraft materials. However, how to improve the atomic oxygen (AO) resistance of vitrimers remains un-explored, although it is critical for extending the lifetime of spacecraft at low earth orbit. Herein, we fabricate a series of AO resistance epoxy...

To estimate Brillouin frequency shift with high accuracy and less computational burden, the mixed moment is used to estimate it for the distributed optical fiber sensor. Its computational burden is much less than that of the typical algorithms. Meanwhile, it is free of curve fitting and...

Copper sulfides (Cu x S) have been considered as candidates for sodium ion battery (SIB) anodes because they are environmentally friendly and have large theoretical capacity. Whereas, the cycle stability and capacity of Cu x S are still challenge for their practical applications. Here,...
