Various techniques are provided to secure a memory polymer component in a flow path. In one embodiment, a method includes providing a memory component in a rest state, performing a deformation operation to transition the component from the rest state to a deformed state, inserting the component into a flow path defined by interior side walls of a structure, and applying a stimulus to transition the component from the deformed state to an intermediate state in which the component abuts the side walls to secure the component in the flow path. Additional devices, systems, and related methods are also provided.

Retention of deformable memory material in flow path

Various techniques are provided to determine the presence of trace chemicals corresponding to various materials of interest. In one example, a method includes providing a chemical reporter of a chemical detector. The chemical reporter includes protonated 2-[5-methoxy-2-(4-phenyl-quinoline-2yl)-phenyl]-ethanol. A vapor-phase amine compound is subsequently received at the chemical reporter. The chemical detector then detects a response of the chemical reporter to the amine compound to determine whether materials of interest are present. Additional methods and related devices are also provided.

Fluorescence-based chemical detection of amine-based substances

Various techniques are provided to determine the presence of trace chemicals corresponding to various materials of interest. In one example, a method includes receiving a vapor-phase nitric acid precursor. The vapor-phase nitric acid precursor is subsequently hydrolyzed in the presence of an acid catalyst to form nitric acid. The nitric acid is then received at a chemical reporter of a chemical detector. A response of the chemical reporter to the nitric acid is detected by the chemical reporter to determine whether materials of interest are present. Additional methods and related devices are also provided.
