Accounting for nonlinearity—constitutive relations improve modeling of fiber-reinforced polymer composites

Modeling the mechanical behavior of fiber-reinforced polymer composites is difficult because of their nonlinear response to external stimuli. Constitutive relations offer one way to account for the nonlinearity, and a team of researchers in Russia used this approach to model polymer composites designed as shut-off valves for pressure vessel service equipment.

Extracting proteins from pottery: Researchers advance proteomic profiling of ceramic artifacts

There are relatively few examples of successful recovery and identification of archeological protein residues from ceramic artifacts. Researchers led by the University of Catania in Italy looked to advance the application of proteomics to ancient ceramics by investigating prehistoric pottery from the Maltese Bronze/Iron Age site of il-Qlejgħa tal-Baħrija.
