Wet air oxidation (WAO) and catalytic wet air oxidation (CWAO) were investigated as suitable precursors for the biological treatment of industrial wastewater containing sodium dodecylbenzene sulfonate (DBS). Two hours WAO semi-batch experiments were conducted at 15 bar of oxygen partial pressure (P(O2)) and at 180, 200 and 220 degrees C. It was found that the highest temperature provides apprec...

The lubricity of drilling fluid resistant to high-temperature over 200 ℃ is still one the technological breakthroughs. In this study, graphene modified with sodium dodecylbenzene sulfonate (SDBS) was selected as a lubricant. Our results show that fluids have high stability after aging at 240 °C assistance SDBS/graphene. Excitingly, tribological performance test revealed SDBS/graphene exert exce...

Abstract We investigated the origin of n-type thermoelectric properties in single-wall carbon nanotube (SWCNT) films with anionic surfactants via experimental analyses and first-principles calculations. Several types were employed to fabricate SWCNT drop-casting, followed by heat treatment at various temperatures. In particular, sodium dodecylbenzene sulfonate (SDBS) surfactant heated 350 °C ex...

Nowadays, there is an enormous demand for constructing housing that needs to be catered a short span of time, with minimum transportation costs and in ecological manner. Biobased materials are considered promising resource buildings the twenty-first century due their sustainability versatility. This article discusses biopositive low-cost renewable “green” technologies used low-rise multi-functi...

background detergents and difficulties of their presence in the water and wastewater cause various problems such as foam production, anomalies in the growth of algae, and accumulation and dispersion in aqueous environments. objectives the aim of this study was to examine and compare the moving bed biofilm reactor with another reactor without media (carries) for anionic surfactants removal. mate...

Abstract Flexible p–n thermoelectric generator (TEG) technology has rapidly advanced with power enhancement and size reduction. To achieve a stable supply highly efficient energy conversion, absolute chemical stability of n‐type materials is essential to ensuring large temperature differences between device terminals ambient stability. With the aim improving long‐term operation carbon nanotubes...

This research aimed to study the effects of individual components on physicochemical properties systems composed surfactants, polymers, oils, and electrolytes in order maximize recovery efficiency kerosene while minimizing impact environment human health. Four independent factors, namely anionic surfactant sodium dodecylbenzene sulfonate (X1) (SDBS), oil (X2) (kerosene), water-soluble polymer p...

In this paper, the effect of using CaMg(CO3)2/Ethylene Glycol-water (50:50%) as a working fluid on thermal performance thermosyphon heat pipe was experimentally studied. Nanofluid prepared by two-step method 2% concentration CaMg(CO3)2 nanoparticle and 0.05% surfactant (Sodium dodecylbenzene sulfonate). For experimental set-up, straight copper one-meter length used. The inner diameter is 13 mm,...
