Nano-TiO2 is widely applied in the automobile exhaust hose reels as a catalyst to reduce oxynitride emissions, including nitric oxide (NO). In the biomedicine field, NO plays an important role in vasodilation and edema formation in human bodies. However, the deswelling activity of nano-TiO2 has not been reported. Here, we demonstrated that nano-TiO2 can significantly degrade the production of N...

Introduction The accurate definition of urban sprawl may be debated but a general consensus is that urban sprawl is characterized by an unplanned and uneven pattern of growth, driven by multitude of processes and leading to inefficient resource utilization. Urban sprawl has become a pejorative term without any serious examination of its qualities or benefits and without any critical analysis of...

The amount of pollutant gases in the atmosphere has reached a critical state due to an increase in industrial development and the rapid growth of automobile industries that use fossil fuels. The combustion of fossil fuels produces harmful gases such as carbon dioxide, nitrogen monoxide (NO), soot, particulate matter (PM), etc. The use of Dimethyl Ether (DME) biofuel in diesel engines or other c...

The world’s rapidly dwindling crude oil supplies, their rising cost and the rapid growing of automobile pollutions from fossil fuels have led to an intensive search for alternative fuels. Experiments were conducted to evaluate the performance and control the exhaust emissions from two-stroke, single cylinder, spark ignition (SI) engine, with alcohol blended gasoline (80% gasoline and 20% ethano...

The determination of the optimal carrying capacity procurement of rail and shipping services in the automobile intermodal network with unique characteristics is essential to save automobile delivery cost. In this research we develop a two-stage stochastic programming model for the tactical-level decision problem arising in the special automobile intermodal network. Furthermore, we improve the s...

Tightening emissions legislation for vehicles across the world has caused the use of monolith catalysts in automobile emission control to become ubiquitous. In this study, the physiochemical transformations caused by thermal pre-oxidation of the surface of Fecralloy ® foil, an integral component of emissions control catalysts, have been studied to assess their role on coating film adherence. Th...

Predicting the toxicity of mixtures is an important current problem, and I'll talk about my personal view of the matter. I think that there are two broad classes of mixtures, one of which is the disposal mixtures: things that go into dump sites. These are highly variable from one site to another, since they depend on specific industrial operations, and it's difficult to extrapolate from site to...

One technology that seems to be promising for automobile pollution reduction is the Homogeneous Charge Compression Ignition. This technology still faces auto-ignition and emission control problems. This paper focuses on the emission problem, since it is incumbent to realize engines that pollute less. For this purpose, this paper presents results concerning the measurement of the emissions of CO...
