Prior to film deposition‚ commercial glass substrates were ultrasonically cleaned by using deionized water‚ ethanol‚ and acetone for 15 min‚ respectively. Then‚ the substrates were dried in an oven at 80°C for 10 min. The substrates were dipped in the prepared sols and then withdrawn at a constant dip-coating speed of 15 mm/min. After each deposition‚ all samples were preheated at 200°C for 10 min to remove the solvent and organic

for particulate matters as they are more exposed part of the plant (Samal and Santra‚ 2002). Trees capture more particulate matter as compared to shrubs and herbs. The structure of tree crowns leads to turbulent air movements‚ which increase PM deposition on leaves (Fowler et al.‚ 1989). Trees‚ with their large total leaf area‚ are considered the most effective type of vegetation for this purpose (McDonald et al.‚

Importance of Biogas plant as a source of: renewable energy and organic fertilizer a case study of Bangladesh. By Sohel Ahmed Email: expertisebd@gmail.com Abstract. Energy is one of the basic ingredients required to alleviate poverty and socio-economic development. The energy prospect is generally assessed on the basis of available commercial sources of energy i.e.‚ fossil fuel like gas‚ coal‚ oil etc. Worldwide‚ there is a major transition underway in the energy sector. Biogas can

Like i said before‚ the nitrogen depositions that are left in the soil and water in the park. Over time these depositions get worse and mess up the ecosystem. Some dangerous chemicals and pesticides can also mess with the water. Because the mountains are cold throughout the 365 days of the year it concentrates the chemicals

Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger

In addition to the injuries that are caused to the plants and trees when exposed to wet and dry deposition‚ the impacts might extend to reach the forest ecosystem highly including the soil properties and the atmospheric conditions.
