Abstract: Certain embodiments provide ligand-metal composite materials and compositions that could serve as catalyst-reductive agents to accelerate PFAS compounds defluorination. Certain embodiments provide optionally substituted 2,2?-bipyridine and 1,10-Phenanthroline ligand coordinated zero-valent metal as described herein and their use for defluorinating PFAS compounds.

Abstract: The invention provides a catalyst comprising 1) Ru0 and 2) Pd0, Pt0, Rh0, or Ir0, on a solid support. The catalyst is useful for water purification applications. In particular, the catalyst is useful for reducing ClO3? and ClO2? from water. The invention also provides catalysts that are useful for reducing nitrate in a water supply and methods for their use.

Abstract: Described herein are heterogeneous catalysts for removing impurities, such as halogen oxyanions (e.g., ClO4? and ClO3?), from a fluid, the catalyst can comprise: an oxygen atom transfer (OAT) transition metal, a Group VIII metal, and a support, where the transition metal, and the Group VIII metal can be in physical communication with the support either directly or indirectly through each other, whereby the catalyst can chemically remove impurities from the fluid. Certain embodiments provide catalysts that further comprise nitrogen donor ligand(s). Accordingly, such catalysts that comprise the OAT transition metal in the form of a complex with one or more nitrogen donor ligands have enhanced efficiency in reducing halogen oxyanion (e.g., ClO4?) to Cl?. Also described are methods or kits for making the catalysts and methods or reactor for the treatment of a fluid utilizing the catalyst.

Abstract: A light bulb apparatus includes a flexible circuit board, LED modules, a control circuit, a driver circuit and a bulb head. The flexible circuit board is rolled as a hollow tube with a cap. The LED modules are disposed on the flexible circuit board. The control circuit is used for controlling turn-on and turn-off of the LED modules in a predetermined pattern. The driver circuit is connected with an electrode terminal on the cap. The bulb head receives external power supply.

Abstract: A synchronous adjustment mechanism for use in a steam iron includes an active module and a passive module. The active module is operable to adjust steam emission rate of the steam iron. The passive module is operable to adjust temperature of a soleplate of the steam iron. The active module and the passive module are cooperatively associated with each other, so that when the active module is operated to adjust the steam emission rate of the steam iron, the passive module is driven by the active module to synchronously adjust the temperature of the soleplate.

Abstract: A steam mop includes a mop body, a steam generator and a control system. The mop body includes a hollow mop head having side and bottom steam outlets. The control system includes a hollow valve seat, a valve member and a pushbutton. The valve seat communicates with the steam generator and the side and bottom steam outlets. The valve member is movable relative to the valve seat such that the control system is switchable between first and second states where the steam generated by the steam generator is expelled respectively from the bottom and side steam outlets. The pushbutton is coupled to the valve member, and is operable to drive movement of the valve member for switching the control system between the first and second states.
