successful worldwide. Several reports have argued that the perovskite metal oxide has the ability to promote the conversion of soot into CO 2 in catalytic traps. The perovskite metal oxide is a general formula ABO 3 , in which the A site is generally

that the pool boiling performance decreased while adding those nanoparticles. Trisaksri and Wongwises [ 14 ] carried out an experimental study to investigate the pool boiling heat transfer performance of titanium oxide nanoparticles TiO 2 based R141b

saturated fatty acid (stearic and palmitic). BRM oil and BBM oil exhibited lower stability to oxidation due to its high total unsaturated fatty acid (oleic and linoleic) as reported by Kodali [ 23 ]. Moreover, the ultra/violet visible spectrophotometer

corrosion, a passive oxide adherent film is usually formed in various environments. The amphoteric nature of the oxide film causes it to dissolve significantly when the metal is placed in a high concentration of acidic or basic media [ 5 ]. After the oxide

oxides are added at 2% and when they are exposed to elevated temperatures of about 900 °C, the loss in mass is found to be less than the control specimen without LaSrCoO 3 oxides in it [ 13 ]. When sustainable or waste materials are used in the concrete
