Urban civilization has a high impact on the environment and human health. The pollution level of indoor air can be 2–5 times higher than outdoor pollution, sometimes it reaches up to 100 or more in natural/mechanical ventilated buildings. Even though people spend about 90% their time indoors, importance quality is less noticed. Indoor treated with techniques such as chemical purification, venti...

The spectroscopic methods UV-Vis absorption, FT-IR and (13)C and (19)F NMR demonstrate that 1,2-diiodoperfluoroethane (DIPFE) and 1,6-diiodoperfluorohexane (DIPFH) display strong halogen bonding with halide anions. A 1 : 1 stoichiometry of DIPFE or DIPFH with halide anion is confirmed, and the bonding constants and molar extinction coefficients are obtained. With the same halide, DIPFH possesse...

population growth and urbanization increase the demand for developing new roads. heavy traffic of the east of tehran imposes high pressure on transportation. network of this city and old road of tehran-rudehen does not meet this need. therefore, constructing the new highway (tehran – pardis) in the east of tehran would be needed. but the new highway passes through protected area of jajrood an...

PM2.5 aerosols were collected in forests along north latitude in boreal-temperate, temperate, subtropical and tropical climatic zones in eastern China, i.e., Changbai Mountain Nature Reserve (CB), Dongping National Forest Park in Chongming Island (CM), Dinghu Mountain Nature Reserve (DH), Jianfengling Nature Reserve in Hainan Island (HN). The mass concentrations of PM2.5, organic carbon (OC), e...

Freight village (FV) is a logistics phenomenon with broad economic, social and environmental consequences. A well organized and knowledge-based planning process is critical to realize sustainable development of FVs, due to its capability to avoid negative phenomena (e.g., unnecessary FV projects, high vacancy rates, unsuitable sites, disturbance to local residents, air and water pollutions) fro...

Analysis of U.S. Custom Service records for 2001-2003 indicates that nearly 1.7 billion pounds of pesticide products were exported from U.S. ports, a rate >32 tons/hour. Exports included >27 million pounds of pesticides whose use is forbidden in the United States. WHO Class 1a and 1b pesticides were exported at an average rate of >16 tons/day. Pesticide exports included >500,000 pounds of known...

Electric vehicles are considered as technology which can significantly reduce the problems related to road transport such as increasing GHG emissions, air pollutions and energy import dependency. The core objective of this paper is to analyze the current energetic, ecological and economic characteristics of different types of electric vehicles. The major conclusions of this analysis are: The hi...

We demonstrate a promising strategy to combine the micro-electromechanical film bulk acoustic resonator and the nanostructured sensitive fibers for the detection of low-concentration formaldehyde vapor. The polyethyleneimine nanofibers were directly deposited on the resonator surface by a simple electrospinning method. The film bulk acoustic resonator working at 4.4 GHz acted as a sensitive mas...
