Abstract: Antibacterial coatings and methods of making the antibacterial coatings are described herein. A first branched polyethylenimine (BPEI) layer is formed and a first glyoxal layer is formed on a surface of the BPEI layer. The first BPEI layer and the first glyoxal layer are cured to form a crosslinked BPEI coating. The first BPEI layer can be modified with superhydrophobic moieties, superhydrophilic moieties, or negatively charged moieties to increase the antifouling characteristics of the coating. The first BPEI layer can be modified with contact-killing bactericidal moieties to increase the bactericidal characteristics of the coating.

Abstract: Low power combustible gas sensors using a thermocouple design are provided. In one aspect, a combustible gas sensor includes: at least one first electrode; at least one second electrode formed from a dissimilar material from the first electrode; and a catalytic material at an active reaction junction between the first electrode and the second electrode, wherein the active reaction junction between the first electrode and the second electrode forms a thermocouple. A sensing device is including, e.g., multiple sensors, and a method for sensing combustible gas using the present sensors are also provided.

Abstract: Antibacterial coatings and methods of making the antibacterial coatings are described herein. In particular, a method for forming an organocatalyzed polythioether coating is provided in which a first solution including a bis-silylated dithiol and a fluoroarene is prepared. A second solution including an organocatalyst is prepared. The first solution and the second solution are mixed to form a mixed solution. The mixed solution is applied to a substrate, and the substrate is cured.

Abstract: Methods and systems for cleaning an optic include measuring a state of the optic. It is determined whether the optic needs to be cleaned based on the measured state of the optic. The optic is cleaned with ultrasonic vibrations if the optic needs to be cleaned.
