On the basis of granular synthetic zeolites NaY, HY, and ZSM-5, adsorbents containing nanoparticles silver, cobalt, molybdenum, tungsten were obtained. The samples have a lower surface polarity in comparison with initial zeolites, which is reflected selectivity number respect to argon. This due fact that argon molecule interacts only through nonspecific forces. Modification was performed by int...

Nano γAl2O3 has been one of the nanometal oxides that improved characteristics biodiesel. The effect nanoparticles addition on premixed flame combustion is investigated with an experiment laminar speed Calophyllum inophyllum methyl ester 30% and 70% petrodiesel mixtures, at atmospheric pressure preheated temperature T = 473K. added to CIME30 biodiesel were 0ppm, 100ppm, 200ppm, 300ppm. Experime...

the reaction of ch₃nh₂ with o₂ on the singlet potential energy surfaces (pes) was carried out using the b3lyp, ccsd(t) and g3b3 theoretical approaches along with 6-311++g(3df,3pd) basis set. the suggested mechanism for the title reaction consists of one pre-reactive complex. from the pre-reactive complex, nine types of products, ch2nh+h2o2, ch3nh+ooh, nh2cho+h2o, ch2nho+h2o, nh3+hcooh, ch2nh+h2...

In this work, plasma has been used as a simple, very fast, low energy and efficient method for modification of the zinc oxide nanopowder to improve its photocatalytic activity. Zinc is one effective photocatalysts in degradation organic contaminants, e.g. dyes. The purpose photocatalyst reduce band gap thus increase activity visible light range. To achieve nitrogen-doped nanoparticles (N-Doped ...

The atmospheric aerosol particles have a potential heavy burden on environment, climate, and human health, which were closely related to the surface physicochemical properties. Time-of-flight secondary ion mass spectrometry (TOF-SIMS) technique is powerful tool obtain detailed chemical information since it has high sensitivity for both elements molecular ions, resolution. In this work, size-fra...
