Hydrogen is seen as one of the important energy carriers of the future with potential to reduce local as well as global warming. The main by-product of the combustion of hydrogen in air is water vapor and trace quantities of oxides of nitrogen. An experiment was conducted to study the impact of hydrogen/natural gas blends on performance, thermodynamic efficiency and exhaust gas emissions in ...

Titanium silicate-2 (TS-2) is synthesized in the presence of different amounts of methylamine. The as-synthesized samples were characterized using IR, DRS UV and SEM techniques. The effect of hydrogen fluoride and methylamine on the synthesis is studied. Results showed that the TS-2 crystallinity and titanium content in the framework increase with addition of both hydrogen fluoride and methylam...

in this paper, a modified sol-gel method using peroxotitanic acid sol (pta) was applied for the preparation of tio2 nanostructured thin films on glass plates. the peroxotitanic acid sol was synthesized using titanium isopropoxide, isopropylalchol, h2o and hydrogen peroxide. tio2 films were then calcined at 500oc and characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem)...

In this paper, the effect of adding hydrogen to the composition of methane and air in a micro combustor is investigated by a three-dimensional numerical method. First, the results of the current study in determining the wall temperature of the micro combustion chamber are compared with those obtained from the experimental and numerical results of the previous research. By confirming the numeric...

a range of some iranian monofloral honeys were assayed for antibacterial activity with and without hydrogen peroxide which is inactivated by the addition of catalase. i t was found that the high amount of antibacterial activity in honeys was due to a factor other than hydrogen peroxide. the test microorganism staphylococcus aureus, was not inhibited by the acidity or the osmolarity of the honey...
