Abstract: A dual function material is provided that captures carbon dioxide from ambient air, i.e., direct air capture, and converts the CO2 to a desired product such as methane. The material includes a high surface area carrier such as Al2O3 upon which catalysts and alkaline adsorbents are positioned proximate each other. In the presence of reactive gas such as hydrogen, the catalysts reduce the adjacent adsorbents to generate additional active sites and enhance the amount of CO2 captured by the material. Once the material becomes saturated with CO2, hydrogen is reintroduced to reduce the catalyst, such as ruthenium, at which time the adsorbed CO2 can migrate from the adsorbent to the catalyst for catalytic conversion to methane. The materials can be employed in isothermal, cyclic reactor systems where target species are bound and then desorbed to reactivate the material, e.g., bind more target species for desorption and/or conversion to additional product.

Abstract: A prepaid wagering card and a system and method for playing the lottery over a telephone line using the prepaid wagering card are provided. The prepaid wagering card includes information that makes it convenient to obtain the prepaid wagering card and use it to wager sets of numbers listed thereon, while also ensuring that the information remains secure. Participating in a lottery using the prepaid wagering card simply involves calling a wagering system from a telephone and providing requested information. Thus, a user can purchase a prepaid wagering card and decide on which scheduled lottery to actually wager using the prepaid wagering card.

Abstract: In an electrochemical fuel cell, an electrode substrate has an in-plane nonuniform structure. The electrode substrate having an in-plane nonuniform structure enables controlled transport of reactant toward the electrocatalyst layer and controlled transport of reaction product away from the electrocatalyst layer.

Abstract: An electrocatalyst material for use in an acid electrolyte environment, comprising platinum or a platinum alloy supported on a conductive support, and gold, gives unexpectedly improved performance over similar electrocatalysts without gold.

Abstract: The present vibrating bucket screen attachment for cleaning beaches and for being mounted on mobile machines such as skid-steer loaders includes an outer excavating bucket with a sand-scooping blade and runners on the outer bucket for supporting the outer bucket relative to the beach. An inner vibrating screen bucket is resiliently mounted in the excavating bucket and includes a hydraulically operated vibrator. Resilient bumper pad mounts disposed between the inner and outer buckets suppress the vibrations of the inner vibrating bucket relative the outer excavating bucket. A floor screen portion of the inner bucket is mounted above bottom, sand-engaging portions of the outer bucket such that the screen portion is spaced from the surface of the beach to vibrate freely during the separation of sand from litter.
