Tunnel magnetoresistance in alumina, magnesia and composite tunnel barrier magnetic tunnel junctions
, 2010 Using magnetron sputtering, we have prepared Co-Fe-B/tunnel barrier/Co-Fe-B magnetic tunnel junctions with tunnel barriers consisting of alumina, magnesia, and magnesia-alumina bilayer systems. The highest tunnel magnetoresistance ratios we found were 73%

Treatment effect on the adsorption capacity of alumina for removal fluoride
Nano Biomedicine and Engineering, 2010 Acid and base treated alumina particles were studied to assess their capacities for the adsorption of fluoride from aqueous solutions. The surface morphology of untreated alumina was analyzed by SEM and its crystal structure was checked by XRD, and was ...

The effect of alumina nanofillers size and shape on mechanical behavior of PMMA matrix composite [PDF]
Journal of the Serbian Chemical Society, 2014 Composites with the addition of alumina nanofillers show improvement in mechanical properties. The PMMA polymer was used as a matrix and two different types of nanofillers, having extremely different shapes were added in the matrix to form the ...

Controlling the size and shape of Mg-MOF-74 crystals to optimise film synthesis on alumina substrates [PDF]
, 2017 Mg-MOF-74 is a metal organic framework with the highest CO2 adsorption capacity of any porous material. Therefore, it has been suggested for CO2 separations as both an adsorbent and incorporated into membranes.

Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

The effect of thermal annealing on the properties of thin alumina films prepared by low pressure MOCVD [PDF]
, 1995 Thin amorphous alumina films were prepared on stainless steel, type AISI 304, by low pressure metal-organic chemical vapour deposition. The effect of thermal annealing in nitrogen (for 2, 4 and 17 h at 600, 700 and 800 °C) on the film properties ...

Improved masers for X-band and Ku band [PDF]
, 1973 Slow-wave structure of traveling-wave maser utilizes comb system which is comprised of ruby on one side and alumina on other; alumina also supports isolator material. Radiation at pump frequency is coupled to ruby through shaped alumina strips.
