摘要： Fluidic systems and methods for analysis are provided. In some embodiments, systems and methods for improved measurement of absorbance/transmission through fluidic systems are described. Specifically, in one set of embodiments, optical elements are fabricated on one side of a transparent fluidic device opposite a series of fluidic channels. The optical elements may guide incident light passing through the device such that most of the light is dispersed away from specific areas of the device, such as intervening portions between the fluidic channels. By decreasing the amount of light incident upon these intervening portions, the amount of noise in the detection signal can be decreased when using certain optical detection systems.

摘要： An apparatus and method for measuring the isoelectric pH for materials deposited on or otherwise affixed onto and in contact with an electrode surface, and a method for utilizing the isoelectric pH to form nanometer thickness, self-assembled layers on the material, are described. Forming such layers utilizing information obtained about the isoelectric pH values of the substrate and the coating is advantageous since the growth of the coating is self-limiting because once the surface charge has been neutralized there is no longer a driving force for the solid electrolyte coating thickness to increase, and uniform coatings without pinhole defects will be produced because a local driving force for assembly will exist if any bare electrode material is exposed to the solution. The present self-assembly procedure, when combined with electrodeposition, may be used to increase the coating thickness. Self-assembly, with or without additional electrodeposition, allows intimate contact between the anode, electrolyte and cathode which is required for successful application to solid-state batteries, as an example.

摘要： A titration method uses a tracer in the titrant or titrand to quantify the amount of titrant added. The method does not require quantitative addition of titrant or sample. The tracer can be inert or can participate as an indicator of the titrant-analyte reaction. The tracer concentration is quantified by an appropriate method depending upon the type of tracer and analytical performance desired (e.g. precision, accuracy). The method simplifies titrations because it eliminates the need for a precision dispensing device and analytical balance.

摘要： A method for detecting hydrocarbons is described. The method includes performing a remote sensing survey of a survey location to identify a target location. Then, an underwater vehicle (UV) is deployed into a body of water and directed to the target location. The UV collects measurement data within the body of water at the target location, which is then analyzed to determine whether hydrocarbons are present at the target location.

摘要： The invention describes a method of ozone titration sensing which utilizes an ozone addition to a target solution, detection of ozone using an Oxidation-Reduction Potential (ORP) electrode or an Ultraviolet (UV) absorption photodiode or other means to detect ozone and the determination of the relative concentration of organics or pathogens subject to ozone oxidation which are present in the target solution. The inventive sensing method can be usefully employed to determine the relative concentration of pathogens such as viruses, bacteria and/or parasites that are readily oxidizable by ozone in aqueous solutions. The inventive sensing method may be used to control an ozone (or other oxidizing or disinfecting) compound dispensing system to optimize the dosage of ozone (or other disinfecting compound) necessary to produce a desired kill ratio or to generate a desired residual of ozone concentration in an aqueous solution after pathogen disinfection.
