Corrosion Characteristics of a - Ti and Ti 2 Cu Composing Ti - Cu Alloys

A series ef binary Ti-Cu alloys containing 5-20 mass% Cu was prepared, and the corresien behavior of a-Ti and Ti2Cu composing the Ti-Cu alloys were examined based on the anodic polarization curves and released iens in O.9% NaCl and 1% lactic acid solutions. In both selutions, the Ti-Cu alloys showed the same anodic polarization curves as titanium in the conditien below 1.4 V. Hewever, precipita...

Role of Ca off - Centering in Tuning Ferroelectric Phase Transitions in Ba ( Zr , Ti ) O 3 System

We here report the substitution effects of the smaller Ca for the bulky Ba in the (Ba1-xCax)(Ti-1-yZry)O3 perovskite oxides for two systems (Ba1-xCax)TiO3 with y=0 and (Ba1-xCax)(Ti0.9Zr0.1)O3 with y=0.1. Ca off-centering was found to play a critical role in stabilizing the ferroelectric phase and tuning the polarization states in both systems. It was demonstrated that the atomic displacement d...

Electronic Conduction in Ti/Poly-TiO2/Ti Structures

Recent intensive investigations on metal/metal oxide/metal structures have targeted nanometric single grain oxides at high electric fields. Similar research on thicker polycrystalline oxide layers can bridge the results to the prior literature on varistors and may uncover novel ionic/electronic features originating from the conduction mechanisms involving grain boundaries. Here, we investigate ...

Retrograde Tuning of Tuning

One way to localize sounds is to measure differences in sound intensity at the two ears. This comparison is made in the lateral superior olive, where signals from both ears converge. Magnusson et al. in this issue of Neuron show that dendritic GABA release can regulate this comparison, which may allow animals localizing sounds to adapt to listening conditions.
