Laminar flow-based fuel cell (LFFC) is a relatively new type of fuel cell that does not require the use of proton exchange membrane. While the first-generation LFFC uses dissolved oxygen at the cathode, the second-generation LFFC (2G-LFFC) adopts a more advanced air-breathing design for...

Residential energy consumptions of both electricity and fuels are associated with emissions of many air pollutants. Temporally and spatially resolved energy consumption data are scarce in China, which are critical for a better understanding of their environmental impacts. In this study, a...

The Atkinson cycle engines have larger expansion ratio, thus higher thermal efficiency, which are more suitable for the hybrid fuel-electric vehicles than the conventional Otto cycle engines. Larger expansion ratio in an Atkinson cycle engine can be realized by increasing the geometrical...

In this study, TiO2 nanosheets codoped with boron and fluorine were prepared by a one-pot hydrothermal method and investigated for photocatalytic dye degradation and disinfection. The as-prepared TiO2 materials were characterized by field emission scanning electron microscope (FE-SEM),...
