Three-dimensional (3D) printing has had a large impact on various fields, with fused deposition modeling (FDM) being the most versatile and cost-effective 3D technology. However, FDM often requires sacrificial support structures, which significantly complicates processing increases cost. Furthermore, poor layer-to-layer adhesion greatly affects mechanical stability of 3D-printed objects. Here, ...

The emergence of nanomaterials (NMs) has made everyone more aware the close relationship between size and performance materials. Especially, catalytic properties materials may change dramatically when macroscopic matter goes from bulk to nanometer atomic level. It is very firmly believed that “Small determines macroproperties, contains big science.” Therefore, as chemists hope, it essential rat...
