TL;DR: In this article, two polysaccharides (APS-I and APS-II) were obtained after a successive purification consisting of (1) fractional precipitation using ethyl alcohol; (2) filtration through DEAE-Sephadex A-25; and (3) eluted by water.

TL;DR: In this paper, a geometric approach for design and synthesis of deployable/foldable single loop mechanisms with pure revolute joints is presented, which can be regarded as a combination of the basic kinematic chains with nontrivial mobility intersection, under this approach, the 5R to 8R single-loop mechanisms with symmetric mobility are synthesized systematically.

TL;DR: In this paper, the authors investigated the energy absorption properties of hexagonal metal honeycombs, and the size optimisation of the metal honeycomb energy absorber is performed by using response surface method (RSM).

TL;DR: The parabolic cylindrical antenna proposed in this study can be folded completely and can be deployed to the predetermined profile, and provides a novel industrial application of the classical Bennett linkage.

TL;DR: In this paper, a double-vibrator three-component pillared phononic crystal plate is considered and the properties of vibration band gaps of this plate are theoretically analyzed by the finite element method.
