Abstract: Exemplary systems and methods associated with activating fluids using indirect plasma. In particular, liquid can be activated to high concentrations and at high volumes by thinning and mixing the liquid as it is exposed to the plasma, resulting more efficient activation. Further increases in activation can be reached by re-circulating fluid for additional exposure to the plasma. High flow rates can be achieved with integrated systems that utilize multiple activation systems with coordinated control.

Abstract: One or more techniques and/or systems are provided for dispense event verification. For example, a user verification component may be associated with a dispenser that is configured to dispense material, such as a sanitizer dispenser configured to dispense sanitizer. The user verification component may obtain user identification information associated with a user attempting to invoke the dispenser to perform a dispense event of material. The user identification information may be evaluated against a dispense access model (e.g., specifying levels of access to the dispenser for users, such as a first user being allowed to perform up to 10 dispense events of sanitizer every 45 minutes) to determine whether to facilitate or restrict the dispense event. In this way, dispensing of material that may be susceptible to abuse by users (e.g., prisoners, psychiatric ward patients, daycare children, etc.) may be monitored and/or restricted for the safety of such users.
