An electrostatic oiling system for use with single blanks in batch systems having an open spray chamber without the need for a negative vacuum chamber. Further, the provided electrostatic oiling system may utilize induction beams and a charge wall that allows for utilization of a smaller vacuum system. Further, the provided electrostatic oiling system may provide variable blank coverage without the need for metered pumps.

Decontaminating materials and methods of making and using the same are provided. The material comprises a network comprising electrospun polymeric nanofibers and at least 50 grams of metal organic framework (MOF) microparticles per m.sup.2 of the network based on the entire area of the network. A composition of the polymeric nanofibers comprises a hydroscopic polymer. An area of the material is defined by an outer surface of the network. The MOF microparticles are retained between the polymeric nanofibers in the network and are configured to decontaminate a chemical threat agent in contact with the material.

Described are an apparatus for generating and collecting nanospray reactive droplets and a method for analyzing a protein digestion. The apparatus includes a capillary, counter electrode, collection vessel, electrostatic lenses, and voltage control module. The capillary receives a mixture that includes a protein and an enzyme and has an outlet disposed in the aperture to dispense the mixture. The collection vessel has a concave surface to receive a nanospray plume emitted from the capillary outlet. The counter electrode and electrostatic lenses are disposed along a nanospray path defined between the capillary outlet and the collection vessel. Each electrostatic lens is formed of an electrically conductive plate having an aperture therein to pass a nanospray reactive plume. The voltage control module is in electrical communication with and is configured to independently control the voltage of the capillary, the counter electrode, the collection vessel and each of the electrostatic lenses.
