A bow sight mounting system including a forward sight assembly used with conjunction with a rearward sight assembly adjustably mounted to a base plate, each component considered modular. The storage apparatus includes a first cover and a second cover, which are assembled together to form an inner space therebetween for accommodating a reticle or a semiconductor element. The optical-state change material alters irreversibly, the optical article from the pre-activated state of functionality to the activated state of functionality upon interaction with the external stimulus. Accordingly, the present invention also encompasses an improved method for converting a hydrocarbon containing gas and an atomic oxygen-containing gas to a gas mixture comprising hydrogen and carbon monoxide, i.
