A method is provided. The method comprises reacting a reactive solution and a templating agent to form a gel; and calcining the gel to form a catalyst composition comprising homogeneous solid mixture. The homogenous solid mixture contains (i) at least one catalytic metal and (ii) at least one metal inorganic network. The templating agent comprises an octylphenol ethoxylate having a structure [I]: wherein “n” is an integer having a value of about 8 to 20. A catalyst composition prepared using the templating agent having a structure [1] is also provided.

A composition includes a templated metal oxide substrate having a plurality of pores and a catalyst material includes silver. The composition under H2 at 30 degrees Celsius, the composition at a wavelength that is in a range of from about 350 nm to about 500 nm has a VIS-UV absorbance intensity that is at least 20 percent less than a standard silver alumina catalyst (Ag STD). The standard alumina is Norton alumina, and which has the same amount of silver by weight.

Disclosed herein are methods and systems for creating stereoscopic images. A left-eye view image for a stereoscopic image and an imperfect right-eye view image may be received. A smooth optical flow may be generated from the received image representing the left-eye view to the imperfect image representing the right-eye view to produce a first candidate right-eye view. Objects are identified in the imperfect image, and merged into the first candidate right-eye view image to create a right-eye view image. A stereoscopic image is created from the left-eye view image and right-eye view image.

A support frame for use in a lift chair. In one embodiment, the support frame includes a base frame having longitudinally spaced transversely extending front and rear frame base rails; a first longitudinally extending side frame base rail connected to the front and rear frame base rails and a second longitudinally extending side frame base rail connected to the front and rear frame base rails, respectively, the first and second side frame base rails and the front and rear frame base rails being co-planar for supporting the lift chair on a surface; and a force balance member mounted to the rear frame base rail. The force balance member has a transversely extending base portion, a first arm portion extending from the base portion at a first angle αa, and an opposite, second arm portion extending from the base portion at a second angle αb.
