  • Publication number: 20240091757
    Abstract: A method for activating a catalyst is described comprising the steps of: (i) installing a reduced and passivated catalyst containing crystallites of a catalytic metal comprising nickel, cobalt or iron in elemental form encapsulated by a layer comprising an oxide of the catalytic metal in a reactor, such as a steam methane reforming reactor, in which it is to be used, and (ii) heating the reduced and passivated catalyst in the reactor under a vacuum or an inert gas to a temperature in the range (TT?X) to (TT+Y), where TT is the Tammann temperature of the catalytic metal in elemental form in degrees Centigrade, X is 400 and Y is 200, to form a catalytically active surface on the catalyst without requiring the application of a reducing gas.

  • Publication number: 20240083491
    Abstract: A passenger protection unit for a vehicle can comprise an adjustable steering apparatus configured to be lockable at least in a first position and a second position, an instrument panel, an airbag module comprising at least an airbag, a crash control unit, and a retracting mechanism configured to initiate a movement of the steering apparatus in a retracting direction, wherein the crash control unit is configured to release movement of the steering apparatus at least in the retracting direction upon detecting a crash risk or an upcoming crash, wherein the crash control unit is further configured to activate the retracting mechanism, and wherein the crash control unit is further configured to deploy the airbag upon an upcoming crash.

  • Publication number: 20240080007
    Abstract: A coupled resonator filter including a first parallel resonator including a first capacitance connected in parallel with a first inductance. The filter includes a second parallel resonator including a second capacitance connected in parallel with a second inductance and a third parallel resonator including a third capacitance connected in parallel with a third inductance. Magnetic coupling between the first inductance and the second inductance, between the second inductance and the third inductance, and between the first inductance the third inductance occurs in accordance with first, second and third coupling factors, respectively. A frequency response of the coupled resonator filter includes a notch when values of the first coupling factor, the second coupling factor and the third coupling factor satisfy predetermined conditions.

  • Publication number: 20060246113
    Abstract: A bio-synthetic matrix comprising a hydrogel which is formed by cross-linking a synthetic polymer and a bio-polymer is provided. The matrix is robust, biocompatible and non-cytotoxic and is capable of supporting cell in-growth in vivo. The matrix can be tailored to further comprise one or more bioactive agents. The matrix may also comprise cells encapsulated and dispersed therein, which are capable of proliferating upon deposition of the matrix in vivo. Methods of preparing the bio-synthetic matrix and the use of the matrix in vivo for tissue engineering or drug delivery applications are also provided.

  • Publication number: 20060134170
    Abstract: Devices, methods, and compositions for improving vision or treating diseases, disorders or injury of the eye are described. Ophthalmic devices, such as corneal onlays, corneal inlays, and full-thickness corneal implants, are made of a material that is effective in facilitating nerve growth through or over the device. The material may include an amount of collagen greater than 1% (w/w), such as between about 10% (w/w) and about 30% (w/w). The material may include collagen polymers and/or a second biopolymer or water-soluble synthetic polymer cross-linked using EDC/NHS chemistry. The material may additionally comprise a synthetic polymer. The devices are placed into an eye to correct or improve the vision of an individual or to treat a disease, disorder or injury of an eye of an individual.
