The VFA is an important property not only as a measure of relative durability but also because there is an excellent correlation between this property and percent density. If the VFA is too low, there is insufficient asphalt to provide durability and to over-densify under traffic and bleed. ...
As a result, air pollution is now recognised as the single largest environmental threat to public health [1]. Although air pollution has decreased in most European countries over the past two decades, including Ireland, levels of ambient air pollution remain above WHO guidelines in many cities ...
Essentially, flood discharge atomization is also a type of fluid movement that can be described according to continuum mechanics [29]. In this paper, the water–air mixture is regarded as a single fluid, ignoring temperature changes, and its flow follows the laws of mass conservation and ...
Experts have regarded the technology as apossible “game-changer” in the battle against climate change and solution to the globe’sincreasing energy crisis.The technology involves mixing air with NaOH, then electrolyzing(电解) the Na2COs torelease(释放) pure CO2. This is then reacted with H2...
The overall best performing sensible heat storage material is found as a mixture of desert sand and granular carbon having the highest thermal efficiency of 80.05%; however, the lowest performance is demonstrated by cement with 9.5% of thermal efficiency. View article Journal 2022, Renewable and ...
The aluminum–air battery is considered to be an attractive candidate as a power source for electric vehicles (EVs) because of its high theoretical energy density (8100 Wh kg−1), which is significantly greater than that of the state-of-the-art lithium-ion batteries (LIBs). However, some...
