In this work, a new organic-inorganic composite filter was prepared. The thickness, pore size, air permeability, bursting strength and microstructure were characterized systematically, proving that coatings had regulatory effect on filters physical properties. Benefitting from the distinct coatings containing 5% sepiolite nanofibers after five times dilution, the physical properties of correspo...

The paper addresses the issue of control of world technological development under prescribed constraints on the emission of greenhouse gases. We use a stylized mathematical model of the world GDP whose growth leads to the increase of industrial emission provided investment in “cleaning” technology is insufficient. The proportion between investment in industrial technology and investment in “cle...

Based on the perspective of ecological compensation and claims, this paper analyzes stability Beijing Tianjin Hebei haze governance alliance by using asymmetric evolutionary game model, obtains optimal strategy combination. The results show that: a reasonable standard is very important for enterprises to adopt energy-saving emission reduction strategies. Only when total value claims in two plac...

Small diesel engines are widely used for commercial vehicle and passenger car applications due to their higher torque requirements, fuel economy, and better thermal efficiency. These engines are exposed to different operating and environmental conditions and hence emissions from these engines are erratic. Strategies are required to enhance performance and reduce engine-out emissions considering...
