(1) Vanadium, molybdenum , niobium, titanium, chromium, nickel, manganese are but a few of the many metals which make their way into steel to yield alloys with special properties.

(2) The corresponding loss in yield strength is compensated by alloying with vanadium, nitrogen, chromium, molybdenum , and titanium.

(3) Common hydroprocessing catalysts consist of an aluminum oxide carrier on to which the metals molybdenum and nickel or cobalt are added.

(4) We added copper, cobalt, selenium, molybdenum , etc to the deficient soils and transformed the plant and animal health.

(5) One might be able to recover from waste relatively pure metals, such as chromium and molybdenum , which are for all practical purposes identical to unused materials.
