Abstract:
Catalyst articles comprising substantially only a palladium precious metal component and related methods of preparation and use are disclosed. Disclosed is a catalyst article comprising a first layer formed on a carrier substrate, wherein the first layer comprises a refractory metal oxide and has a surface that is substantially uniform; and a second layer formed on the first layer, wherein the second layer comprises i) an oxygen storage component that is about 50-90% by weight of the second layer and ii) a palladium component in an amount of about 10-150 g/ft3 of palladium, wherein the palladium component is substantially the only platinum group metal component. One or more improved properties are exhibited by the catalyst article.

Abstract:
The present invention relates to a new wild-type lipase, its nucleic acid sequences and the amino acid sequences thereof. This new lipase shows washing performance in the form of wild-type. The present invention also relates to the method for producing the lipase and the uses of the lipase in baking.
Abstract:
A process for forming a composite film on a substrate comprises providing a suspension comprising an ionised polymer and functionalised carbon nanotubes in a solvent, at least partially immersing the substrate and a counterelectrode in the suspension, and applying a voltage between the substrate and the counterelectrode so as to form the composite film on the substrate. Electrical charges on the polymer and on the nanotubes have the same sign and the voltage is applied such that the charge on the substrate has the opposite sign to the charge on the polymer and the nanotubes.
Abstract:
The present invention is generally related to modified or mutated respiratory syncytial virus fusion (F) proteins and methods for making and using them, including immunogenic compositions such as vaccines for the treatment and/or prevention of RSV infection.
Abstract:
Catalyst articles comprising palladium and related methods of preparation and use are disclosed. Disclosed is a catalyst article comprising a first catalytic layer formed on a substrate, wherein the first catalytic layer comprises palladium impregnated on a ceria-free oxygen storage component and platinum impregnated on a refractory metal oxide, and a second catalytic layer formed on the first catalytic layer comprising platinum impregnated on an oxygen storage component and rhodium impregnated on a zirconia-coated or yttria-coated alumina. The palladium component of the catalyst article is present in a higher proportion relative to the other platinum group metal components. The catalyst articles provide improved reductions in NOx in exhaust gases, particularly after lean-rich aging.
Abstract:
A portable electronic device includes a carrying structure and defines a mounting hole and an opposite strap hole. The carrying structure includes a snap module received in the mounting hole, having a pressing element, a snap element, a knuckle element and an elastic element, and a strap. The strap has two strap connecting ends connecting to the knuckle element and the strap hole. The pressing element has two extending portions, each of which has a wedge-shaped surface. The snap element has three wedge-shaped engaging portions. One engaging portion engages the knuckle element, latching the snap element with the knuckle element. The knuckle element and the snap element are unlockable by pressing the pressing element, where the one engaging portion disengages from the knuckle element, and anther two engaging portions slide aslant along the wedge-shaped surfaces. The elastic element has two ends resisting the snap element and the pressing element.
Abstract:
A hinge assembly includes a positioning module, a connecting module and a rotating module. The positioning module includes a sleeve. The connecting module includes a pivot tube and an shaft. The pivot tube is rotatably attached to the sleeve. The shaft is slidably and rotatably received in the pivot tube. The rotating module is rotatably attached to one end of the shaft.
Abstract:
A method of power down control (PDC) for a display device is to be implemented by a processor in a power down controller of the display device. The power down controller includes a main system, a main system power source, and a PDC power source. The method includes the steps of: (A) receiving power from the PDC power source, determining if the main system is to be activated, and proceeding to step (B) if affirmative; (B) turning on the main system power source, and activating the main system; (C) determining if operation in a power down mode is intended, and proceeding to step (D) if affirmative; and (D) turning off the main system power source to operate in the power down mode. Further, a state parameter is stored that allows the main system to be restored to the operating state prior to a power interruption.
Abstract:
A rotary mechanism includes a base (10), a cover (30), a torsion spring (40) and a locking module (60). The cover is rotatably mounted to the base. Two ends of the torsion spring are fixed with the base and the cover respectively. The locking module limits the cover rotation relative to the base. When the cover overcomes the limitation of the locking module, the cover is automatically rotated relative to the base by the torsion spring.
