Abstract: An antimicrobial material can include one or more fibers and a plurality of metal ions. Each fiber can have a plurality of cellulose molecular chains with functions groups. The metal ions can be impregnated within the one or more fibers such that each metal ion forms a coordination bond between functional groups of adjacent cellulose molecular chains. The one or more fibers can exhibit a cellulose-I lattice structure. In some examples, the antimicrobial material is provided as a surface layer in or on a substrate.

Abstract: The invention relates to a kit and methods for quantitative detection of steroids in a sample. The kit comprises quantitative charge tags and an oxidizing agent.

Abstract: A circuit interruption device includes at least one constriction zone. The constriction zone provides for interference with arcing of an electrical signal. The device may include at least one expansion zone. The device may include at least one movable component to assist in creation of the at least one constriction zone. A method of fabrication is provided.

Abstract: A method for biolithographical deposition of molecules is provided. According to an embodiment of the method, a reactive layer (e.g., a polysaccharide mass) having a surface region coated with a biologically compatible resist is provided. A portion of the biologically compatible resist is selectively removed to expose an exposed portion of the reactive layer. Molecules, such as biomolecules and/or cellular species, are then conjugated to the exposed portion of the reactive layer. Also provided are materials and devices related to the method.

Abstract: The deposition of chitosan onto electrode surfaces is disclosed. Methods of depositing chitosan on surfaces are disclosed. Materials comprising chitosan deposited on a substrate are also disclosed.

Abstract: A switchable thermal circuit breaker (10) has an automatically resettable, current carrying thermostatic disc (14) cantilever mounted in a housing (12) and carries a movable contact (14b) into and out of electrical engagement with a stationary contact (14c). A disc coupling member (16) is pivotally mounted above the disc and has fingers (16e, 16f) to capture opposed sides of the disc so that the disc coupling member pivots concomitantly with movement of the disc. A radially extending blade (18c) of a pivot member is biased by a spring (18k) into engagement with a stop surface (16k) of the disc coupling member when the contacts are in the engaged position and is movable under the stop arm (16g) when the disc moves to the contacts disengaged position to prevent reengagement of the contacts.

Abstract: A method is provided for electrochemically depositing a polysaccharide mass having a selected physical state. According to an embodiment, an electrically conductive support of a substrate is contacted with an aqueous solution including a selectively insolubilizable polysaccharide, and the selectively insolubilizable polysaccharide is electrochemically deposited on the electrically conductive support while controlling deposition conditions to form the polysaccharide mass having the selected physical state, such as that of a hydrogel. Deposition may be performed in a spatially and/or temporally controlled manner.

Abstract: A method is provided for electrochemically depositing a polymer with spatial selectivity. A substrate having a substrate surface is contacted with an aqueous solution containing a selectively insolubilizable polysaccharide, such as chitosan, which is subjected to electrochemically treatment to deposit, with spatial selectivity, the selectively insolubilizable polysaccharide on a patterned electrically conductive portion of the substrate surface.
