Magnetite coated iron wire and molybdenum oxide-coated molybdenum wire as pH sensor.

Preparation and Evaluation of a Polyimide-Coated Ultrafine Gilt Molybdenum Wire and Its Knitted Mesh Used for Electromagnetic Reflectors

In this work, polyimide (PI) was coated onto an ultrafine gilt molybdenum wire in order to protect the gilt surface and prepare an electrically stable wire mesh material which can be widely used in space. The surface of the PI-coated gilt molybdenum wires was characterized using FTIR, SEM, and EDS. Factors such as temperature stability of the PI coating, mechanical properties of the PI-coated g...

Removal of Fe2+ from Aqueous Solution Using Manganese Oxide Coated Zeolite and Iron Oxide Coated Zeolite

The adsorption of Fe2+ by the manganese oxide coated zeolite (MOCZ) and iron oxide coated zeolite (FOCZ) was studied. Surface properties of adsorbents have been investigated for monitoring their changes and morphology for both of the MOCZ and FOCZ. Main variables namely; contact time, pH, initial concentration of Fe2+, size and dosage of adsorbent have been optimized, and the results contrasted...

Coated-wire iron(III) ion-selective electrode based on iron complex of 1,4,8,11-tetraazacyclotetradecane

The work described here comprises the determination of Fe(III) by ion selective potentiometry using a coated-wire ion-selective electrode (CWISE) based on iron–cyclam complex. Linear Nernstian response for this electrode was obtained over the total Fe(III) concentration range of 1× 10−2 to 1× 10−6 M in 0.05 M HNO3, H2SO4, HClO4, HCl, KNO3 and KCl media, with a slope of 60± 5 mV per decade chang...

Enhanced Field Emission from Diamond Coated Molybdenum Emitters

The field emission characteristics of individual Mo emitters were measured before and after diamond deposition, as well as before and after annealing. After coating without annealing, the emission current increased dramatically. Subsequent annealing resulted in further increases in emission and improved current stability. After coating, the energy distribution of the emitted electrons was found...
