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...

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...

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...

The kinetics of single-walled carbon nanotube rebundling have been investigated by photoluminescence (PL) spectroscopy. The rate of loss of PL intensity was measured for 12 different nanotubes in three common aqueous surfactants (sodium dodecyl sulfate, SDS; sodium dodecylbenzene sulfonate, SDBS; and sodium cholate, SC) as the surfactant suspensions were diluted to promote nanotube rebundling, ...

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...

Phase contrast and epifluorescence microscopy were utilized to monitor morphological changes in human astrocytoma cells during a time-course exposure to single-walled carbon nanotube (SWCNT) conjugates with different surfactants and to investigate sub-cellular distribution of the nanotube conjugates, respectively. Experimental results demonstrate that cytotoxicity of the nanotube/surfactant con...
