Flexible mechanical metamaterials
TL;DR: In this article, the design principles leading to these properties are identified and discussed, in particular, linear and mechanism-based metamaterials (such as origami-based and kirigami based metammaterials), harnessing instabilities and frustration, and topological and nonlinear metam materials.

Biomechanics of cellular solids.
TL;DR: The mechanics of a wide range of natural cellular materials and their role in lightweight natural sandwich structures and natural tubular structures are examined, as well as two examples of engineered biomaterials with a cellular structure, designed to replace or regenerate tissue in the body.

Design of materials with extreme thermal expansion using a three-phase topology optimization method
Ole Sigmund,Salvatore Torquato +1 more
TL;DR: In this article, a three-phase topology optimization method was proposed to find the distribution of material phases that optimizes an objective function (e.g. thermoelastic properties) subject to certain constraints, such as elastic symmetry or volume fractions of the constituent phases, within a periodic base cell.

Encystation and expression of cyst antigens by Giardia lamblia in vitro
Frances D. Gillin,David S. Reiner,Michael J. Gault,Herndon Douglas,Siddhartha Das,Annette C. Wunderlich,Judith F. Sauch +6 more
TL;DR: In these studies, encystation of Giardia lamblia in vitro was demonstrated by morphologic, immunologic, and biochemical criteria and will aid in understanding the differentiation of an important protozoan pathogen.

The anisotropic behavior of Poisson's ratio, Young's modulus, and shear modulus in hexagonal materials
TL;DR: In this paper, a method of calculating the anisotropy of Poisson's ratio is applied to trigonal and tetragonal crystals in the literature, and the method of calculation is extended to hexagonal crystals.
