A sensor module is disclosed herein. The sensor module includes a skin piercing member carried by the carrier. The skin piercing member has a skin piercing end positioned opposite from a base end. The skin piercing member defines a lumen that extends along the central longitudinal axis from the skin piercing end toward the base end and the lumen having a lumen axis. The sensor module also includes a blood sample analysis zone located entirely within the lumen of the skin piercing member and a capillary flow stop for stopping capillary flow at a predetermined location within the lumen of the skin piercing member. The sensor module includes an elongated working electrode positioned within the lumen. The working electrode has a length that extends along the lumen axis where at least a section of the working electrode is positioned within the analysis zone. The working electrode includes sensing chemistry.

The present application discloses novel amino-sulfide metal catalysts for organic chemical syntheses including hydrogenation (reduction) of unsaturated compounds or dehydrogenation of substrates. The range of hydrogenation substrate compounds includes esters, lactones, oils and fats, resulting in alcohols, diols, and triols as reaction products. The catalysts of current application can be used to catalyze a hydrogenation reaction under solvent free conditions. The present catalysts also allow the hydrogenation to proceed without added base, and it can be used in place of the conventional reduction methods employing hydrides of the main-group elements. Furthermore, the catalysts of the present application can catalyze a dehydrogenation reaction under homogenous and/or acceptorless conditions. As such, the catalysts provided herein can be useful in substantially reducing cost and improving the environmental profile of manufacturing processes for a variety of chemicals.

A sensor module is disclosed herein. The sensor module includes a main housing defining an analysis zone within the housing. The sensor module also includes a skin piercing member mounted within the main housing. The skin piercing member is movable relative to the main housing between a retracted position and an extended position. The main housing of the sensor module defines a fluid sample flow passage that extends from a sampling end of the main housing to the analysis zone. The fluid sample flow passage includes a funnel structure through which the skin piecing member extends when in the extended position. The fluid sample flow passage also includes capillary flow enhancing slots that extend outwardly from opposite sides of the funnel structure.

Methods and systems for use of switchable water, which is capable of reversibly switching between an initial ionic strength and an increased ionic strength, is described. The disclosed methods and systems can be used, for example, in distillation-free removal of water from solvents, solutes, or solutions, desalination, clay settling, viscosity switching, etc. Switching from lower to higher ionic strength is readily achieved using low energy methods such as bubbling with C02, CS2 or COS or treatment with Bronsted acids. Switching from higher to lower ionic strength is readily achieved using low energy methods such as bubbling with air, inert gas, heating, agitating, introducing a vacuum or partial vacuum, or any combination or thereof.

A solvent that reversibly converts from a hydrophobic liquid form to hydrophilic liquid form upon contact with water and a selected trigger, e.g., contact with CO2, is described. The hydrophilic liquid form is readily converted back to the hydrophobic liquid form and water. The hydrophobic liquid is an amidine or amine. The hydrophilic liquid form comprises an amidinium salt or an ammonium salt.

Emulsions containing a hydrocarbon liquid in a continuous phase and alcohol and/or water in a dispersed phase. The emulsions are stabilised by an emulsifier and a coupling agent. The emulsifier is a copolymer containing at least one relatively hydrophobic polymeric block of styrene or ring substituted styrene monomer, and at least one relatively hydrophilic polymeric block of at least one monomer, such as ethylene oxide, selected from the group having the formula H(O-R)nOH where R is an aliphatic radical containing from 1 to 4 carbon atoms and n is a number between 20 and 300. The coupling agent is a copolymer containing at least one polymeric block of styrene or ring substituted styrene monomer, and at least one block being of a saturated or unsaturated aliphatic hydrocarbon moiety, such as butadiene. The emulsifier is present in an amount sufficient to form micelles of the relatively hydrophilic polymer block sufficient to contain the dispersed phase and the coupling agent is present in an amount that is sufficient to substantially prevent the dispersed phase droplets from coalescing while not being present in a sufficiently high amount that micelles of the styrene containing polymeric blocks of the coupling agent form in the continuous phase of the emulsion.
