Direct ink writing of piezoresistive isoprene rubber nanocomposites
Polymer Composites, EarlyView.Use of carbon nanoparticles as conductive fillers in an isoprene rubber matrix for piezoresistive sensors fabricated via direct ink writing. Abstract Despite the growing interest in flexible electronics and wearable sensors, research in piezoresistive polymer nanocomposites has stagnated in consideration of the polymer matrices, particularly in ...

PLANTS, PEOPLE, PLANET, EarlyView.Herbarium collections are powerful, yet underutilized, tools for global biodiversity conservation and protected area management. By integrating digitized herbarium records with existing biodiversity data, previously unknown plant species were uncovered, exposing critical gaps in conservation knowledge.

Small, EarlyView.The effect of CeO2 on the Pt nanoparticles nucleation and growth and on the activity versus the oxygen reduction reaction was studied by in situ synchrotron wide‐angle X‐ray total scattering. The most active catalyst (MA = 423 A g−1; SA = 446 µA cm−2) shows greater stability than the commercial benchmark as demonstrated by accelerated stress tests at ...

Small Science, EarlyView.Selenium‐doped ruthenium phosphide (Ru2(P0.9Se0.1)) is obtained via ion‐engineering techniques. Ru sites in Ru2(P0.9Se0.1) act as primary catalytic centers, optimizing intermediate adsorption energies. The precisely controlled Se doping enhances the Ru−OH moieties formation on the surface while preventing Ru dissolution.

Plant Species Biology, EarlyView.Recent research has ignited a renewed interest in Ceratozamia cycads, unveiling their remarkable diversity. While previous studies primarily focused on morphology, this investigation employs a multidisciplinary approach, integrating phylogenetics, morphology, and ecological niches. Our methods identify seven distinct lineages as separate species.

Animal Conservation, EarlyView.Environmental DNA is a powerful tool for simultaneous detection of rare species and their pathogens. We confirmed the presence of Atelopus at multiple sampling locations and found that the concentration of the amphibian pathogen Bd in eDNA samples was correlated with stream characteristics and the pathogen load of the amphibian community.

Archaeometry, EarlyView.Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)
