millions of dollars are being spent worldwide on the repair and maintenance of sewer networks and wastewater treatment plants every year. the production and emission of hydrogen sulfide has been identified as a major cause of corrosion and odor problems in sewer networks. prediction of hydrogen sulfide production in the sewer system helps the engineers and manager to obtain a proper strategy fo...

The growing environmental concerns associated with global warming along the exponential rise in energy demand are boosting production of clean energy. combined process biomass pyrolysis and in-line catalytic steam reforming is a promising alternative for selective hydrogen from renewable sources. This Primer provides general overview fundamental aspects that influence potential process. Recent ...

The hydrolysis of sodium borohydride as a source of hydrogen gas is studied at different mole ratios of H+ to NaBH4. The sulfonated porous carbon (SPC) is used as a source of hydrogen ion and catalyst. It is found that the sulfonated porous carbon exhibits high activity for the hydrolysis of NaBH4 to generate hydrogen gas at room temperature in comparison to Amberlyst-15 and Nafion-NR50. The ki...

In this study, the effect of the levels of hydrogen addition to methane-air premixed flame in a micro-stepped reactor has been studied numerically. In addition, the effects of mixture velocity and walls’ thermal conductivity (Kw) on the flame’s location, temperature, and species distribution in a micro reactor were calculated using a 2D numerical laminar steady code. The results showed that an ...

While microfiltration has seen wide acceptance in water treatment, the irreversible fouling of microfilters remains as biggest impediment to their long-term performance. Thus, developing a better understanding mechanisms is crucial. To this end, we investigated mechanism effluent organic matter (EfOM)-membrane interactions responsible for polyvinylidene fluoride (PVDF) membranes during wastewat...

Abstract Light‐emitting electrochemical cells (LECs) have attracted considerable attention owing to their unique luminescence mechanisms and device structures, making them suitable for solution processing. However, these encounter problems related color purity, which plays an important role in efficient high‐resolution displays. Here, two types of solution‐processed LECs are reported that exhib...
