The present invention relates to cylinder packages utilized in the delivery of highly toxic and/or flammable compounds to semiconductor manufacturers. More specifically, the present invention provides a cartridge adapted to removably attach to the gas outlet of a gas discharge passageway in a cylinder valve provided on a toxic gas containing cylinder package, the cartridge comprising a cylindrically shaped housing having at least one end fitted with a barrier member permeable to the toxic gas contained within the cylinder package and the housing containing a toxic-gas getter material.

Coated iron oxide (10) nanocrystal structures, superparamagnetic 10 nanoparticles, methods for synthesizing coated 10 nanocrystal structures, and methods for synthesizing superparamagnetic 10 nanoparticles are described herein. A coated 10 nanocrystal structure may comprise an iron oxide core, a manganese ferrite shell layer surrounding the core, and a bilayer coating surrounding the shell layer. The bilayer coating may include an inner oleic acid layer surrounding the shell layer and an outer layer surrounding the inner oleic acid layer.

The invention relates to a lithium adsorption-desorption apparatus including a plurality of reaction tanks arranged in a row; a guide rail disposed at an upper portion of the reaction tank; a movable driving unit coupled to a moving means that moves along the guide rail; and a reaction housing which is mounted to the driving unit, and can be vertically moved or rotated in a state in which the lithium adsorbent is fixed thereto, and after immersing in the reaction tank, accelerates adsorption or desorption of lithium, and after being lifted, discharges residual solution from the lithium adsorbent by rotation movement. Therefore, the lithium adsorption desorption apparatus can fix a large amount of lithium adsorbent and immerse it in a lithium-containing solution to effectively adsorb lithium and then quickly desorb lithium in a desorption solution, and can efficiently wash the lithium adsorbent in a cleaning solution.

The present invention relates to the use of a particulate mineral material being functionalized with one or more reducing agents for lowering the amount of heavy metal contaminants ions from an aqueous medium. Furthermore, the present invention relates to a corresponding process for lowering the amount of heavy metal contaminants from an aqueous medium as well as to a functionalized particulate mineral material. Additionally, the present invention relates to a process for preparing a functionalized particulate mineral material and to a scavenging complex.
