Gas-Filled Hohlraum Fabrication

Microfluidic fabrication of stable gas-filled microcapsules for acoustic contrast enhancement.

We introduce a facile approach for the production of gas-filled microcapsules designed to withstand high pressures. We exploit microfluidics to fabricate water-filled microcapsules that are then externally triggered to become gas-filled, thus making them more echogenic. In addition, the gas-filled microcapsules have a solid polymer shell making them resistant to pressure-induced buckling, which...

Argonne Gas-filled Fragment Analyzer-AGFA

As the premier stable-beam user facility in the USA, ATLAS is currently being upgraded to provide high intensity (>1 pμA) stable beams. The combination of new highefficiency detectors and intense beams will move ATLAS to the forefront as a world research center for studying exotic nuclei, such as super-heavy nuclei, nuclei at or near the proton drip line, proton-rich nuclei near 100 Sn and neut...

Fabrication of Magnetic Co/Pt Nanodots Utilizing Filled Diblock Copolymers

The potential of nanosphere lithography utilizing di-block copolymers is demonstrated. The starting configuration is a single layer of micelles, filled with silica, deposited on a ferromagnetic system. After removing the organic shell the SiO2 cores remain on the surface and are used as shadow mask for a succeeding ion milling process. It is demonstrated how the magnetic properties of the dots ...

FABRICATION OF GAS - FILLED TUNGSTEN - COATED GLASS SHELLS by A . NIKROO , W . BAUGH , and D . A . STEINMAN SEPTEMBER 2003

Deformable gas-filled microbubbles targeted to P-selectin.

Ultrasound contrast microbubbles have been successfully targeted to a number of intravascular disease markers. We hypothesized that targeted delivery could be improved further, by making the microbubbles deformable, leading to increased microbubble-endothelium adhesion contact area and stabilized adhesion. Activated leukocytes utilize such strategy; they deform after binding to inflamed endothe...
