The First Table of Atomic Site Coordinates of the Ih Quasicrystal

1. Introduction The mathematical derivation and classification of the 230 space groups were completed and perfected independently by Fedorov, Schoenflies, and Barlow before the twentieth century [1]. It was only later, in 1912, that Laue’s discovery of X-ray diffraction initiated...

Monomer Sequence Architecture Tunes the Performance of Poly(octadecyl acrylate- co -styrene) Pour Point Depressants in Waxy Oils

Abstract Monomer sequence architecture is an underexplored design parameter for polymeric pour point depressants (PPDs). Here, octadecyl acrylate-styrene (OA-St) copolymers with statistical, block, and gradient architectures were synthesized by free-radical and reversible additio...

Influence of liquid film in star wheel tip clearance on dynamic characteristics of single screw compressor
