The paper deals with the analysis of the friction force between the breech block carrier and receiver assembly in the amphibious rifle when firing in air and firing underwater by experimental method.

Strongly segregating block copolymers (BCPs) are attractive as a means of forming 10 nm scale lithographic features. Here, we report directed self-assembly of polyhedral oligomeric silsesquioxane ...

This article presents a design for interlocking blocks and an algorithm that allows these blocks to be assembled into desired shapes. During and after assembly, the structure is kinematically ...

We report the fabrication of ultradense circular nanolines of block copolymer (BCP) microdomains over macroscopic areas. These lines were generated by the directed self-assembly (DSA) of BCPs on the ...
