Microbubbles show peculiar properties, such as shrinking collapse, long lifetime, high gas solubility, negative electric charge, and free radical production. Fluids supersaturated with various gases can be easily generated using microbubbles. Oxygen microbubble fluid can be very useful for oxygen delivery to hypoxic tissues. However, there have been no reports of comparative investigations into...

Combinatorial designs have long had substantial application in the statistical design of experiments, and in the theory of error-correcting codes. Applications in experimental and theoretical computer science, communications, cryptography and networking have also emerged in recent years. In this paper, we focus on a new application of combinatorial design theory in experimental design theory. E...

We present here an example of an important biomedical technique in which it is critical to understand and avoid bubble nucleation in supersaturated aqueous solutions of oxygen. By doing so it is possible to inject highly supersaturated oxygen solutions through a small capillary without the formation of significant gas bubbles. The potential medical benefits of a successful technique of this kin...

A supersaturated design is a design whose run size is not enough for estimating all the main effects. It is commonly used in screening experiment, where the goal is to identify sparse and dominant active effects with low cost. In this paper, we study a variable selection method via Dantzig selector, proposed by Candes and Tao (2007), to screen active effects. A graphical procedure and an automa...

Two-level supersaturated designs (SSDs) are designs that examine more than n− 1 factors in n runs. Although SSD literature for both construction and analysis is plentiful, the dearth of actual applications suggests that SSDs are still an unproven tool. Whether using forward selection or all-subsets regression, it is easy to select simple models from SSDs that explain a very large percentage of ...

This work gives insights into processing and characterisation of bulk nanocrystalline FeCr materials. The investigated alloys, consisting 30, 50 70 at.% ferromagnetic Fe remaining anti-ferromagnetic Cr, are processed by arc melting subsequent severe plastic deformation high pressure torsion. physical similarities between elemental Cr in combination with the structure as-deformed necessitates ad...

The supersaturated solid-solution interfaces between Cu core and Ag shell structures improve their bonding strength greatly prevent the outward diffusion of atoms slow down growth oxides. printed CuAg x electrodes maintain high conductivity for a long time even at 220 °C, which is far better than conventional core/Ag Cu/Ag mixed that rapidly oxidize below 150 °C. These findings not only promote...
