The present invention provides for the use of a metal-organic framework (MOF) in removing particular chemical species or compounds, in particular oxy-anions, from a liquid or liquid stream. In some embodiments, the MOF is a Zr-based MOF, such as NU-1000, and the oxy-anions that are removed include, include, for example, oxy-anions of selenium, including selenite (SeO) and selenate (SeO); oxy-anions of antimony, including oxy-anions in either the Sb[III] (antimonite) or the Sb[V] (antimonate) redox state; and oxy-anions of lead, including oxy-anions in either the Pb[II] or the Pb[IV] redox state, such as Pb(OH), Pb(OH), PbO, and PbO. The Zr-based MOF, including NU-1000 can be used to remove these oxy-anions from various liquid streams in industrial processes such as a nuclear and fossil fuel power plants, including the latter's flue gas desulfurization system.

Metal-organic frameworks for adsorption of liquid phase compounds

The present application is directed to a method for the conversion of nitrous acid to dinitrogen gas. In particular, the present application relates to a method for the conversion of nitrous acid to dinitrogen gas by contacting the nitrous acid with an amine-functionalized metal organic framework.

Method for the conversion of nitrous acid to dinitrogen gas

The present invention provides a metal-organic framework (MOF) for use in removing particular chemical species or compounds from a liquid. In particular, the present invention provides an MOF having a molecular formula of Zr(&#x3bc;-O)(&#x3bc;OH)(OH)(HO)(TBAPy), wherein TBAPy is 1,3,6,8-tetrakis (p-benzoic-acid)pyrene, (known as NU-1000) for use in complexing selenate or selenite from a liquid or liquid stream. Further, the selenium based oxy-anions are removed to concentrations below that specified for wastewater discharge by the U.S. Environmental Protection Agency for flue gas desulfurization operations in the fossil fueled electric power generation industry. Such water treatment results are achieved even in the presence of competing sulfate anion challenges and at elevated temperatures comparable to condensate cooling water.

A method of using a metal organic framework (MOF) comprising a metal ion and an at least bidendate organic ligand to catalytically detoxify chemical warfare nerve agents including exposing the metal-organic-framework (MOF) to the chemical warfare nerve agent and catalytically decomposing the nerve agent with the MOF.

Folding computer

Prior miniaturzed palm-top computers have reduced-size keyboards which are not useful for standard typing. The present invention provides a folding pocket-sized computer, comprising up to a 12' screen, a central processing unit, data storage and input means and a full size computer keyboard. It does this by having the keyboard divided into two halves hingedly connected along a fold line, whereby one of the keys is split along the fold line to permit folding of the keyboard, and by folding the screen and abutting the sections of the screen with no intervening frames.
