Secondary Refining for High Purity Steel.

Use of Nickel and 316L Stainless Steel Filter Assemblies in High Purity Corrosive Gas Distribution Systems

In addition to meeting the requirements of ultra high purity bulk gas distribution systems, the distribution of specialty and corrosive gases necessitates that the gas distribution system is corrosion resistant and does not exhibit any catalytic behavior. Vereecke1 and coworkers reported that reaction between reactive gases and materials of construction employed in gas delivery systems can resu...

High purity amphotericin B.

OBJECTIVES Amphotericin B (AmB) is a drug of choice for treatment of disseminated fungal infections, but its use is often associated with severe adverse effects. Our observation that generic formulations of AmB contain multiple polyene components led us to propose that removal of other polyenes would yield a high purity AmB (AmBHP) with an improved therapeutic index. METHODS To test that prem...

Multiphase Mass Transfer in Iron and Steel Refining Processes

In the present chapter, a computational fluid dynamics (CFD) model for multiphase flow was developed, allowing the simulation of two different processes, the desulfurization of hot metal in a ladle mechanically agitated by an impeller (KR process) and the desulfuri‐ zation of steel in a gas-agitated ladle. The model gives important information to charac‐ terize the fluid flow conditions, to def...

Protective Polymer Coatings for High-Throughput, High-Purity Cellular Isolation

Cell-based therapies are emerging as the next frontier of medicine, offering a plausible path forward in the treatment of many devastating diseases. Critically, current methods for antigen positive cell sorting lack a high throughput method for delivering ultrahigh purity populations, prohibiting the application of some cell-based therapies to widespread diseases. Here we show the first use of ...
