Porous Materials with Tunable Structure and Mechanical Properties via Templated Layer-by-Layer Assembly

The deposition of stiff and strong coatings onto porous templates offers a novel strategy for fabricating macroscale materials with controlled architectures at the micro- and nanoscale. Here, layer-by-layer assembly is utilized to fabricate nanocomposite-coated foams with highly customizable properties by depositing polymer–nanoclay coatings onto open-cell foam templates. The compressive mechanical behavior of these materials evolves in a predictable manner that is qualitatively captured by scaling laws for the mechanical properties of cellular materials. The observed and predicted properties span a remarkable range of density-stiffness space, extending from regions of very soft elastomer foams to very stiff, lightweight honeycomb and lattice materials.

Commentary on Maugham's Treatise on the Laws of Literary Property (1828)

The first British legal treatise dedicated specifically to the law of copyright written by a strong advocate of the common law rights of the author. Maugham, in addition to providing a commentary upon the law of copyright, also used his work to lobby for both an extension to the copyright term (ideally resulting in a perpetual right) and a reduction in the library deposit requirements (arguing that authors should only be required to deposit one copy of their work for the British Museum). In proselytising the need for a change to the law in both areas he drew frequent comparisons with the law of other jurisdictions (in particular France and Germany). The work became a standard point of reference for many British and American authors who followed.
