This article describes a Group (VI) modified Co-Zr-B amorphous nano alloys were prepared in situ ultrasound-assisted reduction by sodium borohydride in an aqueous solution. Co-Cr-Zr-B, Co-Mo-Zr-B and Co-W-Zr-B powders were characterized by XRD, FESEM, BET and ICP techniques. No distinct peak...

In the present work we match the biased hierarchical continuous-time random flight (HCTRF) on a regular lattice (based on hierarchical waiting-time distribution) and the extreme event theory (EVT). This approach extends the understanding of the anomalous transport and diffusion (for example,...

Amorphous materials as diverse as foams, emulsions, colloidal suspensions and granular media can jam into a rigid, disordered state where they withstand finite shear stresses before yielding. Here we give a simple introduction to the surprising physics displayed by a very simple model system for...
