摘要： An electrolysis unit (10) has an ion selective barrier (20) for separating an anodic chamber (12) from a cathodic chamber (14). An electrolyte within the unit includes a precursor, such as potassium acetate, or acetic acid. A positive potential is applied to an anode (16) within the anodic chamber, resulting in the generation of a variety of shorter and longer lived oxidizing species, such as peracetic acid, hydrogen peroxide, and ozone. In one preferred embodiment, a solution containing the oxidizing species is transported to a site where articles, such as medical instruments, are to be decontaminated. The oxidizing species are generated as needed, avoiding the need to store hazardous decontaminants.

摘要： An electrolysis unit (10, 210, 310) has an anode (16, 216,316) and a gas diffusion cathode (18, 218, 318). Air is fed to the cathode (18, 218) to generate peroxide species, such as hydrogen peroxide, peroxide ions, or peroxide radicals by electrolysis of oxygenated water. A peracetic acid precursor, such as acetyl salicylic acid, reacts with the peroxide to form peracetic acid. An ion selective barrier (20, 220) optionally separates the unit into two chambers, an anodic chamber (12, 212) and a cathodic chamber (14, 214). By selecting either a proton permeable membrane or an anion exchange membrane for the barrier, the peracetic acid may be formed in either an alkaline electrolyte in the cathodic chamber or in an acid electrolyte in the anode chamber, respectively.

摘要： A micro-viscosity sensor for measuring the viscosity of a lubricant. The micro-viscosity sensor including at least one finger-like element or an array of finger-like elements vertically extending from the surface of a semiconductor base, the at least one finger-like element being oscillated at a desired frequency. The power required to oscillate the at least one-finger-like element is monitored because the power required is a function of the viscosity of the lubricant. The sensor also includes a temperature detector, wherein the thermal conductivity of the temperature detector varies in correspondence with the temperature of the lubricant. A first set of electrical contacts provides for electrical connection to the at least one finger-like element; and a second set of electrical contacts provides for electrical connection to the temperature detector. The viscosity of the lubricant is determined based on the temperature of the lubricant correlated with the power required to oscillate the at least one-finger like element at a particular frequency.

The mechanically alloyed particles are stable and retain their hydrogen-absorbing efficiency even after prolonged exposure to air and water. Binders and solvent can be added to produce low-viscosity inks. The hydrogen storage system can be used with fuel cells that can be microfabricated and optionally be integrated with electronic devices.

The electrolyte is a proton exchange membrane (PEM) upon which can be printed, by ink jet means, the anode and cathode electrodes and the current collectors that convey current to or from the edges of the PEM which has a thickness on the order of 0.001 to 0.010 inch. Pluralities of the series connected fuel cell stacks can be arranged in electrical and physical parallel with one another to provide what are batteries of fuel cell stacks that can be connected by manifolds to sources of fuel and oxidizer. The invention is directed to a thin, light-weight, flexible fuel cell assembly that can be produced in ambient conditions using standard micro-fabrication techniques, such as thick film printing and ink jet deposition. Thick film printing techniques, screen printing or ink jet printing, are used to deposit porous current collectors on either side of the membrane.
