While ultrafast laser welding is a well-established technique for bonding materials, it not applicable to the silicon–silicon configuration because of nonlinear propagation effects. In article number 2200300, Maxime Chambonneau and co-workers solve this issue by relocating filaments at interface where absorption exalted with metallic nanolayer, yielding remarkable shear joining strength values ...

The design and fabrication of ultrathin polymer layers are of increasing importance because of the rapid development of nanoscience and nanotechnology. Confined, two-dimensional crystallization of polymers presents challenges and opportunities due to the long-chain, covalently bonded nature of the macromolecule. Using an innovative layer-multiplying coextrusion process to obtain assemblies with...

The present study evaluates the toughening capability of electrospun PA66 nanofibers for carbon/epoxy composite laminates subjected to mode II loading conditions at elevated temperatures. Dynamic Mechanical Analysis (DMA) test showed that glass transition temperature produced is in a range ∼60–80 °C. Accordingly, End-Notched Flexure (ENF) specimens interleaved by 50 μm-layer were quasi-static r...
