Disclosed herein is a simple method for generation of high-throughput aerosols of monodisperse micro-shell particles. To create the aerosol, small nozzles are employed blowing slightly compressed air on a thin liquid film. This allows one to generate bubble aerosols consisting of particles having a thin liquid shell surrounding a gas core, which are suspended in a carrier gas flow or environment. The diameter of the created liquid shells is uniform and scales with the inner diameter of the blowing nozzle, enabling control on the size of the produced monodispersed aerosol and formation of particles between few microns to several hundred of microns in outer diameter. The process throughput is very high, reaching several thousands of particles with liquid micro-shells per second for one blowing nozzle. The generated aerosol particles are extremely light-weight (few micrograms) and have very small wall thickness (couple of microns), which enables precise delivery of materials and rapid evaporation of solvent in their liquid walls. The process production rate is easily scalable. In terms of possible applications, liquid used for aerosol generation can be enriched with suspended or dissolved materials, for instance by a medical drug for direct delivery into a patient's airways, or by organic/inorganic solvent which solidifies during drying enabling formation of soft or rigid spherical shells out of particles with liquid shells. The blowing gas can have suspended micron/nano particles in it and these particles will be encapsulated by liquid walls of formed micro-shells, which can potentially solidify during their motion, and thus produced aerosols can be used as transport agents for material delivery. Formation of fine monodisperse liquid or solid foams is possible by collecting liquid micro-shells from the generated aerosol on a surface or in a vessel, while the liquid walls of particles of adhere to each other and then can solidify due to solvent evaporation, freezing or polymerization.

A security tag can prohibit unauthorized usage of a device or product. The device may include an electronic nicotine delivery systems (“ENDS”) device, which may include aerosol delivery devices such as smoking articles that produce aerosol. The security tag can prevent usage until authorized. Attempts at usage without authorization can result in the device being unusable. The authorization may include identity confirmation or age verification.

The present disclosure provides systems, methods and apparatuses for inducing a desired biological response in an organism through the use of one or more repetitive signals from one or a series of LED lights designed to emit the signal with multiple pulsed components. Each component of the signal contains a one or more light color spectrum or wavelength that is within 50 nm of the peak absorption of a photon receptor of the organism corresponding to the desired biological response. Each component has a repetitive ON duration with an OFF duration and an intensity where the relationship between the ON duration and OFF duration of the first component and the second component induces the desired response in the organism through the stimulation or excitation of a molecule associated with a photoreceptor and the reset of the molecule.
