The ability of the complex hierarchical structure of nacre to withstand huge work of fracture beyond its constituent materials has generated much interest in its growth mechanism and biomimicry studies. However, the structural features directly invol

Star-shaped boron suboxide (B 6 O) nanoplates were formed through a liquid-phase reaction of amorphous boron and boron oxide. The formation of the five-vertex B 6 O crystal is attributed to the oxygen-deficient state of B 6 O x , where x 6 O show a h

In the current paper, we present the use of nanostructured boron suboxide (B6O) and in-situ synthesized hexagonal boron nitride (hBN) to form structured composites with commercially available boron carbide (B4C). Taking advantage of the rapid heating

Using a two-dimensional Ginzburg–Landau model and the finite-element computational method, we have calculated stable domain configurations resulting from a second-order ferroelectric phase transition for a finite-sized system. The boundary conditio
