Scientist cooks up adjustable strength metals

As you could know, crafting a katana is a gentle process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. Sooner or later though, smiths and forging fires may well be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. No less than that is what we envisioned after we examine Jörg Weißmüller’s breakthrough research within the field of nanomaterials . The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be utilized to harden the fabric and, for those who change your mind in regards to the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually result in self-healing vehicle armor or scratch-resistant cellphones — but, really, we just wish to zap our option to a high-quality samurai sword.
