In order to understand the dynamics of Z-pinch irnposions of thin wires in pulsepower accelerators, it is necessaryto understandthe physicalprocessby which the initially solid wires are coverted into plasma by rising current. For this purpose, we model wire explosions using TRAC II, a tw~demensional MHD code, in three distinct cases: pure tungsten, impure tungsten, and gold-plated tungsten. We ...

This paper describes the interaction of the NEMI recommended lead-free solder for reflow assembly (Sn3.8Ag0.7Cu) with different commercial printed wiring board (PWB) platings. It also discusses the effects of plating type and manufacturer on the strength of the lead-free solder joints. PWBs from two different manufacturers with the same four types of plating were examined. The platings were org...

Background: Oblique spiral fractures of the distal third of the fibula are commonly encountered in any orthopedic practice. Controversy persists over various fixation methods and their corresponding risks and benefits. Methods: A systematic review of the pertinent literature pertaining to these fractures was performed, and currently published results were summarized. Results: There are advantag...

We present a microfluidic technique for precision patterning thin-film metals (silver and gold) without the need for photolithography. This technique is employed for the fabrication of metal resistors that are subsequently utilized as temperature sensors, strain gauges, and fluid flow sensors. Patterns of thin film metal are fabricated by premixing and flowing electroless silver or gold plating...

Chemical separations play an important role in most chemical, pharmaceutical, and petrochemical processes. Membrane-based separations are potentially important because they can be less energy intensive and more economical than conventional separation methods [1]. By controlling the pore diameter of track-etched nanoporous polymer membranes, they can be used as nanofilters for the separation of ...

Elements 112 through 118 are expected to be very volatile due to strong relativistic effects on their valence electrons. Their volatility is to be studied via the gas-phase thermochromatography technique by measuring the adsorption enthalpy, ∆Hads, on gold plated detectors located along the chromatography column (see results for elements 112 and 114 [1,2]). The obtained ∆Hads is then related to...
