Protective coatings that resist oxide scale growth and decrease chromium evaporation are necessary to makestainless steel interconnect materials for long-term durable operation of solid oxide fuel cells (SOFCs). Inthis study a layer of manganese was coated on the surface of AISI 441 ferritic stainless steel which is used insolid oxide fuel cells for interconnect applications. The oxidation beha...

In this work, a novel thinner derived from natural botany Chinese Larch Tree was obtained by combination lignin with phenol using H2O2 as oxidant and the acting efficiency of lignosulfonate in the drilling fluids is greatly enhanced after oxidation with H2O2. Both the chemical structure and the adsorptive ability of the oxidation...

The vanadium-based catalyst, acts as a homogeneous catalyst for the selective oxidation of various kinds of sulfides with 30% aqueous H2O2. Vanadium-based catalyst was successfully used as the oxygen source for the oxidation of sulfides to sulfoxides for the first time. The sulfoxides were obtained in a good way to high yields without any detectable over-oxidation to sulfones under normal condi...

the perovskite-structured la2cuo4 nanoparticles (lco nps) have been synthesized via an ultrasonic-assisted co-precipitation route using octanoic acidas organic surfactant, and the phase composition, morphology, lattice parameters and size of nanoparticles  are characterized through fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd), scanning electron microscopy (sem) and t...

background: koobideh kebab (barbequed minced meat) is one of the most popular iranian foods. reduction in the water holding capacity (whc) of meat during thermal processing makes the water and melted fat run out of the meat. the fat content of the final product depends on the proportion of the retained moisture and fat. meanwhile, high temperature and the presence of oxygen and iron in meat may...

dehulling is an important step in walnut processing that has considerable effect on the quality, chemical and microbial properties of walnuts. improving dehulling can increase the quality of the final product. this research studied the effect of genotype and hulling method on walnut properties. one experiment was performed as a factorial in a randomized complete block design with three replicat...

an efficient protocol for the selective oxidation of primary alcohols to aldehydes withh5io6/v2o5 in ionic liquid [bmpy][pf6] has been developed. high yields of the products, mildreaction conditions and simple experimental procedure make this protocol complementary tothe existing methods. the catalyst can be reused for several times without obvious loss of thecatalytic activity.
