Shaping metallic glasses by electromagnetic pulsing

With damage tolerance rivalling advanced engineering alloys and thermoplastic forming capabilities analogous to conventional plastics, metallic glasses are emerging as a modern engineering material. Here, we take advantage of their unique electrical and rheological properties along with the classic Lorentz force concept to demonstrate that electromagnetic coupling of electric current and a magn...

Pulsing electromagnetic fields induce cellular transcription.

Weak, pulsing electromagnetic fields can modify biological processes. The hypothesis that responses to such induced currents depend on pulse characteristics was evaluated by using transcription as the target process. Two pulses in clinical use, the repetitive single pulse and the repetitive pulse train, were tested. These pulses produced different results from each other and from controls when ...

Cluster-assembled metallic glasses

A bottom-up approach to nanofabricate metallic glasses from metal clusters as building blocks is presented. Considering metallic glasses as a subclass of cluster-assembled materials, the relation between the two lively fields of metal clusters and metallic glasses is pointed out. Deposition of selected clusters or collections of them, generated by state-of-the-art cluster beam sources, could le...

Superconductivity in Metallic Glasses

Metallic glasses: Family traits.

The disordered atomic structure of metallic glasses gives rise to unique mechanical and physical properties such as strength and elasticity, and are being considered for a wide range of applications. However, to understand and ultimately control these properties, it is important to study their disordered structure. Seen on the macroscale, metallic glasses are isotropic and homogeneous. On the m...
