Abstract: A system and method for efficiently and sustainably producing propylene and acrylonitrile is disclosed which utilizes biodegradable materials, combustible materials that produce carbon dioxide and/or carbon monoxide. According to one embodiment of the invention, a source of carbon dioxide and/or carbon monoxide is utilized and the carbon dioxide and/or carbon monoxide is electrochemically reduced to ethylene. Dimerization is applied to separate the ethylene to produce 1-butene; which is isomerized to produce 2-butene. The 2-butene is metathesized to produce propylene. The propylene may then be subject to ammoxidation as desired in order to produce acrylonitrile.

Abstract: Computer program products and methods for displaying information relating to one or more digital looseleafs are disclosed. In one embodiment, a computer program product includes a computer usable medium having computer readable instructions embodied therein. The computer readable instructions cause a processor to display of a first table of contents page of a digital looseleaf. In response to receipt of a user selection of a representation of an individual one of the plurality of main sections, a second table of contents page is displayed overtop the first table of contents page such that an edge portion of the first table of contents page is unobstructed by the second table of contents page. In response to receipt of a user input in the edge portion of the first table of contents page, an entirety of the first table of contents page is displayed.

Abstract: A thermal desorption apparatus is configured to detect a substance of interest in a sample, the apparatus comprising: a wand configured to support a swab and a detector comprising an analyser arranged to detect a substance of interest, wherein the wand is configured to couple to the detector such that thermal desorption of a sample from the swab provides a part of the sample to the analyser.
