A chitosan based coating system. The coating system includes a carrier agent and a chitosan based agent preservative. The carrier agent may be a cleaning agent, a polishing agent, and/or a finishing agent. The chitosan based agent may be a chitosan acetate and salts thereof, chitosan citrate acetate and salts thereof, or combinations thereof. The coating system may include 0.01-5 weight percent chitosan based agent. The chitosan based agent functions as a preservative to increase both the shelf-life and use-life of the coating system as well as functions as a chelating agent to reduce soap scum.

Provided is a method that achieves tunable crosslinking and reversible phase transition of hydrogels. The method is useful for preparing 3D-printable hydrogel, for example, for wound healing, aneurysm treatment or tissue regeneration.

A disinfecting device for purifying air to reduce the presence of dust and/or pathogens. The device includes a main housing, a battery module configured for installation within a first receptacle in the main housing and a reservoir module configured for installation within a second receptacle in the main housing. The reservoir is configured to hold a disinfecting fluid. The housing also includes an ultrasonic wave emitter electrical power communication with the battery, the ultrasonic wave emitter providing ultrasonic waves to the disinfecting fluid thereby creating a pressurized fluid, a membrane in contact with the pressurized fluid. The membrane generates reduced-size particles of the pressurized fluid which are emitted from a nozzle mounted on the housing.

Paint and coating compositions including a low molecular weight chitosan composition that may be incorporated in a coating composition at higher loading levels, which exhibits one or more of improved elongation, improved thermocycling characteristics, reduced leaching of coating components, are lesser susceptibility to fungal and mildew defacement than conventional coatings or coatings containing higher molecular weight chitosan compounds, articles coated in the same, and methods for making said coatings and coated articles.
