“…401 Helical nanofibres of a tripodal tris(urea) were found by Stanley et al to exhibit similar mechanical properties, but in this system the mechanism of gel collapse in the region of δ was also considered. 402 Noting that the observed values of δ are an order of magnitude lower than expected if failure occurs through elastic buckling, it was proposed that fibre networks collapse via plastic deformation, with individual fibres displaying a plastic yield stress on the order of 1 MPa. Plastic failure in gels is generally marked by a large increase in strain deviating from the linear elastic stress-strain relationship, and involves nonrecoverable processes such as the fracturing of crystallites and breakage of permanent fibre junctions.…”

Advances in the field of supramolecular chemistry have made it possible, in many situations, to reliably engineer soft materials to address a specific technological problem. Particularly exciting are "smart" gels that undergo reversible physical changes on exposure to remote, non-invasive environmental stimuli. This review explores the development of gels which are transformed by heat, light and ultrasound, as well as other mechanical inputs, applied voltages and magnetic fields. Focusing on small-molecule gelators, but with reference to organic polymers and metal-organic systems, we examine how the structures of gelator assemblies influence the physical and chemical mechanisms leading to thermo-, photo-and mechano-switchable behaviour. In addition, we evaluate how the unique and versatile properties of smart materials may be exploited in a wide range of applications, including catalysis, crystal growth, ion sensing, drug delivery, data storage and biomaterial replacement.

“…It has been shown that the mechanical properties of small-molecule gel systems do not match those of a colloidal gel. 42 Instead a more appropriate model is that of a cellular solid which is formed from interconnected load-bearing struts.…”

Knot theory is a branch of pure mathematics, but it is increasingly being applied in a variety of sciences. Knots appear in chemistry, not only in synthetic molecular design, but also in an array of materials and media, including some not traditionally associated with knots. Mathematics and chemistry can now be used synergistically to identify, characterise and create knots, as well as to understand and predict their physical properties. This tutorial r eview provides a brief introduction to the mathematics of knots and related topological concepts in the context of the chemical sciences. We then survey the broad range of applications of the theory to contemporary research in the field. Key Learning Points Some fundamentals of knot theory.  Knot theory and closely related ideas in topology can be applied to modern chemistry.  Knots can be formed in single molecules as well as in materials and biological fibres using a mixture of selfassembly, metal templating and optical manipulation. The inclusion of knots in molecular structures can alter chemical and physical properties.  Knots are surprisingly ubiquitous in the chemical sciences.

“…Common structural features link cellular materials [1,2], polymer gels [3,4], and biological networks [5][6][7]: that of a random lattice of interconnecting struts. These struts can bear mechanical loads by either stretching or bending.…”
