All‐Solid‐State Planar Sodium‐Ion Microcapacitors with Multidirectional Fast Ion Diffusion Pathways

Origin of fast ion diffusion in super-ionic conductors

Super-ionic conductor materials have great potential to enable novel technologies in energy storage and conversion. However, it is not yet understood why only a few materials can deliver exceptionally higher ionic conductivity than typical solids or how one can design fast ion conductors following simple principles. Using ab initio modelling, here we show that fast diffusion in super-ionic cond...

Causal mechanisms and multidirectional pathways between trauma, dissociation, and health.

An anisotropic diffusion filter based on multidirectional separability

Extracting tongue contour from high noised ultrasound image is a key issue of observing speech production procedure. Anisotropic diffusion has been widely used in reducing speckle noise of ultrasound images but it is not very effective in preserving edges and tends to blur them. Hence the blurred edges hamper the succeeding contour-based pattern analysis or modeling. In this study, we modify th...

LOW-ENERGY-ION ENHANCED DIFFUSION AT THE SURFACE OF METALS

Radiation enhanced diffusion at the surface of metals has been observed and studied for low-energy nitrogen ions at the surface of copper. The displacement of the target atoms during irradiation creates vacancies and other defects near the surface, thus enhancing the diffusion of implanted materials toward the surface and also into the solid. The mechanism has been studied here by a specia...

Planar Electrode Quadrupole Ion Traps

We present a linear type ion trap consisting of metal lines that are lithographically patterned onto two ceramic substrates. Trapping fields are realized by applying specific voltage potentials to each line. This arrangement allows miniaturization approaches that are immune to surface roughness issues and increased complexities of precision machining of electrode surfaces. We also present how t...
