NOx emissions in the atmosphere can cause various environmental problems, which should be strictly controlled and regulated. Furthermore, because of limited amount crude oil resources world severe global warming, development fuel-efficient vehicles has long been desired. Accordingly, efficient storage reduction catalysts have developed over decades, called NSR (NOx storage/reduction) catalysts....

Although the electronic properties of graphene layers can be modulated by various doping techniques, most of doping methods cost degradation of structural uniqueness or electrical mobility. It is matter of huge concern to develop a technique to improve the electrical properties of graphene while sustaining its superior properties. Here, we report the modification of electrical properties of sin...

Seed priming is a technique which is potentially able to promote rapid and more uniform seed germination and plant growth as well. In this regards, the presowing effects of seed priming treatments were investigated on some physiological viz. seed germination, germination rate, radicle elongation, shoot elongation, radicle dry weight, shoot dry weight and vigor index. Seeds were subjected to two...

We present a detailed study of the structural behavior and polarization reversal mechanism in phase III of KNO3, an unusual ferroelectric material in which the nitrate groups rotate during polarization reversal. This material was one of several studied in a previous work O. Diéguez and D. Vanderbilt, Phys. Rev. Lett. 96, 056401 2006 where methods were described for computing curves of energy ve...

AIM To compare the plaque inhibition efficacy of a sodium fluoride/potassium nitrate (NaF/KNO3 with 1450 ppm F) test dentifrice to a 0.454% stannous fluoride/sodium hexametaphosphate/sodium fluoride positive control dentifrice (SnF2/SHMP with 1450 ppm F). METHODS AND MATERIALS Twenty-five subjects were randomized to a two-period, two-treatment, double blind crossover sequence using NaF/KNO3 (...

in order to evaluate the effect of priming on germination of black cumin under different levels of salinity, a factorial experiment on base of completely randomized design was conducted with three replications. the main factors consisted of five levels of priming (osmopraiming with kno3 (1 and 3%), salicylic acid (sa) (0.2 and 0.5 mm) and a hydropriming)) and four salinity levels (zero, 75, 125...

Plant density was varied with P, Ca, Mg, and KNO3 in a multifactor experiment to improve Curcuma longa L. micropropagation, biomass and microrhizome development in fed-batch liquid culture. The experiment had two paired D-optimal designs, testing sucrose fed-batch and nutrient sucrose fed-batch techniques. When sucrose became depleted, volume was restored to 5% m/v sucrose in 200 ml of modified...
