Copper is an essential microelement that plays an important role in a wide variety of biological processes. Copper concentration has to be finely regulated, as any imbalance in its homeostasis can induce abnormalities. In particular, excess copper plays an important role in the etiopathogenesis of the genetic disease Wilson's syndrome, in neurological and neurodegenerative pathologies such ...

Recent reports on proteins and related models show that vibrational spectroscopy in the farinfrared domain is a promising technique to characterize metal sphere coordination in proteins. The lowfrequency modes are however complex, and there is a need to develop the analysis of metal sites by means of quantum chemical calculations as a support for useful interpretation of the farIR data. In ...

 · One technique that's being considered a lot is the development of using copper pillars instead of ball grid areas that get to very high density interconnects at the package level, so you can have small integrated systems that can be put on a circuit and have much denser, much smaller systems. The maximum we've measured so far for our thermal vias is 290 watts per metre Kelvin," said Zinn.

Abstract: This paper presents a new method by sticking a copper ring on the permanent magnet pole of the permanent magnet brush dc (PMBDC) motor to reduce the electromagnetic vibration. First, the airgap flux density distribution and radial force density distribution are derived and the principle of the electromagnetic vibration reducing technique by the copper ring is analyzed in detail.
