Road pavements are pivotal to the infrastructure, transportation and ultimate efficiency of both public economy. However, they undeniably having detrimental effects on an already compromised environment. Consequently, a re-think about road pavement construction materials is paramount importance. Cold mix asphalt (CMA) low carbon manufacturing approach production flexible material that has prove...

Maltose as an efficient, available, cheap and eco-friendly catalyst has been applied for the synthesis of 3,4,5-substituted furan-2(5H)one derivatives via a one-pot three-component reaction of arylamines, aromatic aldehydes and dialkyl acetylenedicarboxylates in water. This method has notable advantages in terms of simple workup, no need for column chromatography, short reaction time and high y...
