Abstract: Pre-connected analyte sensors are provided. A pre-connected analyte sensor includes a sensor carrier attached to an analyte sensor. The sensor carrier includes a substrate configured for mechanical coupling of the sensor to testing, calibration, or wearable equipment. The sensor carrier also includes conductive contacts for electrically coupling sensor electrodes to the testing, calibration, or wearable equipment.

Abstract: The invention relates to a method for preparing a saline solution comprising [13N]NH4+. The method comprises following steps: preparing [13N]NH3 gas, transporting [13N]NH3 gas to a diffusion chamber, to a first side of a semipermeable membrane, transporting sterile saline solution to the diffusion chamber, to a second side of a semipermeable membrane, allowing the mixing of [13N]NH3 gas that has penetrated the semipermeable membrane with the saline solution on the second side of the semipermeable membrane, whereby saline solution comprising [13N]NH4+ is obtained, and directing the saline solution comprising [13N]NH4+ out from the diffusion chamber. The invention relates also to use of a device for preparing a radiolabelled saline solution for preparation of a saline solution comprising [13N]NH4+.

Abstract: A method is provided for making a hydrophilic carbon fiber construction, such as a fuel cell gas diffusion layer or diffuser/current collector, by electrophoretic deposition of a metal oxide selected from Type I or Type II, where Type I consists of metal oxides having a negative zeta potential and Type II consists of metal oxides having a positive zeta potential. A hydrophilic carbon fiber construction is provided, such as a fuel cell gas diffusion layer or diffuser/current collector, which is coated with a metal oxide and capable of wicking 200 mg of water per 40 mg of the hydrophilic carbon fiber construction.

Abstract: A method is provided for making a hydrophobic carbon fiber construction, such as a fuel cell gas diffusion layer, by electrophoretic deposition of a highly fluorinated polymer, which may be followed by sintering of the fluoropolymer. A hydrophobic carbon fiber construction is provided, such as a fuel cell gas diffusion layer, which is coated with a monolayer of particles of a highly fluorinated polymer, which may be sintered.
