    Abstract: Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. Depending on a desired proportion, or ratio, of the desired materials, raw materials are added to the solution to achieve the desired ratio of the commingled compounds for the recycled cathode material for new cells. The desired materials precipitate out of solution without extensive heating or separation of the desired materials into individual compounds or elements. The resulting active cathode material has the predetermined ratio for use in new cells, and avoids high heat typically required to separate the useful elements because the desired materials remain commingled in solution.

    Abstract: Device, and methods of using or making the device, for engineering cells in vitro are disclosed. In some aspects, a cell culture device comprises at least one glass or polymer surface configured for incubating cells in a culture medium; a charged molecule electrostatically bound to the surface; and a polyelectrolyte multilayer (PEM) electrostatically bound to the charged molecule, the PEM comprising one or more bi-layers of oppositely charged polyelectrolytes, and the PEM having a sufficient thickness to permit release of the charged molecule into the culture medium in a controlled released manner.

    Abstract: A fiber optic sensing device includes an optical fiber having a polished end defining a flat sensory portion coated with a lossy-mode-resonance (LMR) coating. A reflective coating on an end face of the optical fiber facilitates propagation of a return signal. An optic circuit for identifies a wavelength attenuated by the LMR coating from the return signal reflected by the reflective coating based on a moisture presence at the sensory portion. Various gaseous parameters may be detected based on the coating on the sensory portion. An LMR coating of tin oxide (SnO2) is employed for moisture sensing.

    Abstract: Bauxite residue recovery includes mixing a solution of hydrochloric acid (HCL) according to a predetermined concentration, and adding the HCL solution to a quantity of raw red mud recovered from industrial operations as waste material. The highly alkaline property of the bauxite residue, commonly known as red mud is at least partially neutralized from the HCL, and makes the resulting washed red mud more amenable to subsequent uses in various applications in fields such as construction, wastewater treatment, and metal recovery processes. The process recovers washed red mud from the red mud and HCL solution by filtering the raw red mud and HCL solution for generating a stream of leach liquor from the filtrate and the recovered washed red mud from the residue.

    Abstract: An impact absorbing ski binding interface device includes an elongated top plate having a toe end and a heel end adapted to engage a boot toe and a boot heel, respectively, and a bottom plate adapted to engage a ski, thereby securing the device between the boot and ski. A plurality of constant force spring linkages between the top plate and the bottom plate include a constant force spring linkage between the toe end and the bottom plate, and a constant force spring linkage between the heel end and the bottom plate, such that each of the constant force spring linkages have an opposed pair of deformable members for exerting a counterforce to vertical displacement forces between the top plate and the bottom plate for load mitigation.
