Tracing the ancestral roots of Polish Jews before the introduction of metrical data in 1808 represents a unique and complex challenge for genealogists and historians alike. Indeed, limited official records, shifting geopolitical boundaries, and the a

The fibre–matrix interface plays an important role in the overall mechanical behaviour of a fibre-reinforced composite, but the classical approach to improving the interface through chemical sizing is bounded by the materials’ properties. By cont

Short fibers may serve as toughening agents of composite materials because of the high energy dissipated during fracture, associated with numerous fiber pullouts. An ongoing challenge is to improve their toughness even further, by directing and conce

Natural materials often consist of hierarchical architectures, which are extremely efficient in mechanical terms. Whereas the structure-function relationship is well-studied in natural hard materials, soft materials are not getting equal attention, d

The reinforcement of composites by carbon-nanotubes (CNTs) is typically limited by agglomeration and non-uniform dispersion. Thus, achieving a nanocomposite with high density of reinforcement material is a tough challenge. In this work, rather than m

We examined the combined effect of crosslinking and dual reinforcement on the thermal and mechanical properties of polyvinyl alcohol (PVA). Glutaric acid (GA) was used as crosslinker while tungsten disulfide nanotubes (WSNT) and carboxylated multiwal
