Abstract : Although the study of gels undoubtedly takes its roots within the field of physicochemistry, the interest in gels has flourished and they have progressively become an important object in the study of the mechanics of polymeric materials and volumetric growth, raising some fascinating problems, some of them remaining unsolved. Because gels are multiphase objects, their study represents an important step in the understanding of the mechanics of complex soft matter as well as for the process of shape generation in biological bodies. The scope of this article is to review the understanding we have of the mechanical behavior of gels, with a strong focus on the development of instabilities in swelling gels.
Approaches to the Study of Atg8-Mediated Membrane Dynamics In Vitro - Jotwani, Anjali and Richerson, Diana N. and Motta, Isabelle and Julca-Zevallos, Omar and Melia, Thomas J.

Abstract : Macro-autophagy is the intracellular stress-response pathway by which the cell packages portions of the cytosol for delivery into the lysosome. This ``packaging'' is carried out by the de novo formation of a new organelle called the autophagosome that grows and encapsulates cytosolic material for eventual lysosomal degradation. How autophagosomes form, including especially how the membrane expands and eventually closes upon itself is an area of intense study. One factor implicated in both membrane expansion and membrane fusion is the ubiquitin-like protein, Atg8. During autophagy, Atg8 becomes covalently bound to phosphatidylethanolamine (PE) on the pre-autophagosomal membrane and remains bound through the maturation process of the autophagosome. In this chapter, we discuss two approaches to the in vitro reconstitution of this lipidation reaction. We then describe methods to study Atg8-PE mediated membrane tethering and fusion, two functions implicated in Atg8's role in autophagosome maturation.

Liquid Rope Coiling - Ribe, Neil M. and Habibi, Mehdi and Bonn, Daniel
in ANNUAL REVIEW OF FLUID MECHANICS, VOL 44 edited by Davis, SH and Moin, P (2012)

Abstract : A thin stream or rope of viscous fluid falling from a sufficient height onto a surface forms a steadily rotating helical coil. Tabletop laboratory experiments in combination with a numerical model for slender liquid ropes reveal that finite-amplitude coiling can occur in four distinct regimes (viscous, gravitational, inertio-gravitational, and inertial) corresponding to different balances among the three principal forces acting on the rope. The model further shows that the onset of coiling has distinct viscous, gravitational, and inertial modes that connect smoothly with the corresponding finite-amplitude regimes. In addition to steady coiling, slender liquid ropes falling onto surfaces can exhibit a remarkable variety of nonstationary behaviors, including propagating spiral waves of air bubbles, supercoiling, the leaping-shampoo (Kaye) effect for non-Newtonian fluids, and the fluid-mechanical sewing machine in which the rope leaves complex stitch patterns on a moving surface.
