Effective method of treatment of effluents from production of bitumens under basic pH conditions using hydrodynamic cavitation aided by external oxidants.
TL;DR: Investigations on the use of hydrodynamic cavitation aided by additional oxidation processes (O3/H2O2/Peroxone) to reduce the total pollution load in the effluent from the production of bitumens confirmed that furfural is one of the byproducts whose concentration increased during treatment by hydrod Dynamic cavitation alone as well as hydrod dynamic cavitation aiding by H2O 2 as an external oxidant and it should be controlled during treatment processes.

Investigating the combined impact of plasticizer and shear force on the efficiency of low temperature reclaiming of ground tire rubber (GTR)
TL;DR: In this article, ground tire rubber (GTR) was mechano-chemically reclaimed at ambient temperature using two-roll mills, where road bitumen and styrene-butadiene-styrene (SBS)-modified bitumen at variable content (in range: 2.5-20 phr) were applied as reactive plasticizers to enhance reclaiming of GTR.

TL;DR: In this paper, the effect of bimetallic surface composition (AgPt, AgAu, Au_Pd, AuPt) on the photocatalytic activity in phenol degradation and efficiency of hydroxyl radicals generation under UV-vis light irradiation were investigated.

TL;DR: In this paper, the effect of metal type (mono-and bimetallic modification) as well as deposition method (simultaneous or subsequent deposition of two metals) on the photocatalytic activity in toluene removal in gas phase under UV-vis irradiation (light-emitting diodes- LEDs) and phenol degradation in liquid phase under visible light irradiation, were investigated.
