Abstract:
Use of physical vapor deposition methodologies to deposit nanoscale gold on activating support media makes the use of catalytically active gold dramatically easier and opens the door to significant improvements associated with developing, making, and using gold-based, catalytic systems. The present invention, therefore, relates to novel features, ingredients, and formulations of gold-based, heterogeneous catalyst systems generally comprising nanoscale gold deposited onto a nanoporous support.
Abstract:
Various embodiments of a respirator that includes a harness, a mask body, and an exhalation valve are disclosed. The exhalation valve can include a valve seat and a flexible flap that is in engagement with the valve seat. The flexible flap can have one or more materials that can cause the flap to flash when moving from a closed position to an open position or vice versa. The flashing valve can make it easier for a user to ascertain whether the valve is operating properly.
Abstract:
Illumination articles are described. More specifically, illumination articles that include a wearable device configured for wearing on the head of a wearer, a lightguide and light sources for emitting light into the lightguide are described. The illumination articles allow for wearable devices that uniformly illuminate a working area at high brightness without providing excessive glare to observers.
Abstract:
Heterogeneous catalyst systems, methods of making these systems, and methods of using these systems, wherein catalytically active gold is deposited onto composite support media. The composite support media is formed by providing nanoporous material on at least a portion of the surfaces of carbonaceous host material. In representative embodiments, relatively fine, nanoporous guest particles are coated or otherwise provided on surfaces of relatively coarser activated carbon particles. Catalytically active gold may be deposited onto one or both of the guest or host materials either before or after the guest and host materials are combined to from the composite host material. PVD is the preferred catalyst system of depositing gold.
Abstract:
An apparatus for fluorinating a substrate. The apparatus includes a vacuum chamber and a means for generating a fluorine-containing plasma throughout the entire chamber. The apparatus includes a capacitively-coupled system within the chamber that has at least one electrode powered by an RF source and at least one grounded electrode substantially parallel to the powered electrode. The electrodes are separated by about 25 mm or less.

Abstract:
Various embodiments of a respirator (10) that includes a harness (13, 16), a mask body (12), and an exhalation valve (14) are disclosed. The exhalation valve (14) can include a valve seat (20) and a flexible flap (22) that is in engagement with the valve seat. The flexible flap can have one or more materials that can cause the flap to flash (26) when moving from a closed position to an open position or vice versa. The flashing valve can make it easier for a user to ascertain whether the valve is operating properly.
