Abstract Surfactants tend to adsorb on the surface/interface mostly in a directional manner. The alkyl chain orientation and conformation order for molecular monolayers of sodium dodecylbenzenesulfonate (SDBS) at low concentrations are studied by using sum frequency generation vibrational spectroscopy (SFG-VS). arrangement surfactants adsorbed solid/liquid interface is further investigated. It ...

Poly (urea-formaldehyde) (PUF) shelled dicyclopentadiene (DCPD) microcapsules were prepared by in-situ polymerization technology for self-healing concrete applications. It’s found, during the process, sodium dodecyl benzene sulfonate (SDBS) behaves better in emulsification of DCPD than other surfactant of sodium lauryl sulfate (SLS) and styrene maleic anhydride copolymer (SMA), and the addition...

Liquid-phase exfoliation of two-dimensional materials is very attractive for large-scale applications. Although used extensively, isolating MoS2 layers (<10) with high efficiency reported to be extremely difficult. Further, the importance soaking has not yet been studied and surfactants’ role in stabilizing nanosheets poorly understood (Grayfer et al., 2017) [1]. Herein, we report a novel appro...

ABSTRACT We report results of our analysis the Kepler superaperture LC data open cluster NGC 6791 to search for pulsating sdB stars. checked all pixels and we found only three stars be pulsating, KIC 2569576 (B3), 2438324 (B4), 2437937 (B5). These were known pulsators before, though extended coverage detecting more frequencies features in their amplitude spectra, i.e. new multiplets complete pe...

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, ...

A local wastewater treatment plant (WWTP) experiencing poor nitrification tracked down high level of surfactants in the plant’s influent and effluent. The aims of this project were to assess the potential inhibitory effect of surfactants on activated sludge processes. The effect of the presence of TergitolNP-9, TrigetolNP-7, Trigetol15-S-9, dodecylbenzene sulphonate (SDBS) and sodium dodecyl su...
