Abstract: The present invention relates to reduction of corrosion. The present invention includes a method of decreasing corrosion during ammonia extraction. The method includes performing a process to extract ammonia using ammonia extraction equipment. The ammonia extraction equipment includes an ammonia absorber, an ammonia desorber, and an aqueous solution. The aqueous solution includes an acid or an ammonium salt thereof. The method also includes sparging an oxygen-containing gas into the solution in the ammonia absorber, the ammonia desorber, or therebetween. The invention also provides a system that can perform the method.

Abstract: A novel nickel particulate form is provided that efficiently forms a zero-valent nickel complex with a phosphorus-containing ligands in an organic liquid to form a hydrocyanation catalyst. Particles in the nickel particulate form comprise nickel crystallites. For example, the nickel particulate form can have a BET Specific Surface Area of at least about 1 m2/gm; an average crystallite size less than about 20-25 nm, the nickel particulate form can have at least 10% of the crystallites in the nickel form can have a diameter (C10) of less than about 10 nm, and/or there are on average at least about 1015 surface crystallites per gram nickel. A ratio of BET SSA to C50 for the nickel particulate form can be at least about 0.1×109 m/gm and preferably at least about 0.4×109 m/gm. Methods of preparation and use are also provided.

Abstract: A system and method for monitoring blood pressure of a wearer has an inflatable arm cuff that is selectably inflatable to differing air pressures that incorporates a fabric having both a light transmission property and a light reflection property when the fabric is illuminated with light having wavelength(s) in the range from about 400 to about 2200 nanometers. A radiation source and a detector are attached to the fabric in relative positions such that the reception of incident radiation by the detector is directly affected by a change in the amount of light transmitted through the fabric relative to the amount of light reflected by the fabric as the fabric stretches in response to motion in the wearer's body due to changes in the flow of blood through an artery disposed beneath the fabric occurring in consonance with variations in the air pressure within the inflatable cuff.
