In the synthesis of nanoparticles, phenomenon agglomeration is an undesirable condition because particles formed can be larger. The use surfactants prevent occurrence this phenomenon. study, was studied in nanosilica from geothermal sludge. method applied sol-gel method. A 1 M sodium hydroxide (NaOH) solution used to prepare sol phase, while gel phase prepared at pH 5 using a 1.5 hydrochloric a...

In this paper, the fractal dimension of coal surfaces was calculated using theory, and influence different surfactants on surface studied. Six kinds sustainable traditional used in gas desorption processes were compared analyzed. We mineral fertilizer from Huainan Liuzhuang, China, as research object studied sodium dodecyl benzene sulfonate (SDBS), cohol diethanolamide (CDEA), nonylphenol polyo...

Micro deep drawing (MDD) is a fundamental process in microforming which has wide applications micro electromechanical system (MEMS) and biological engineering. Titanium possesses excellent mechanical properties biocompatibility, makes it preferred material micromanufacturing. In this study, eco-friendly low-cost water-based TiO2 nanolubricants were developed applied the MDD with 40 μm-thick pur...

The hyper-eutrophic conditions in impoundments used for irrigation around South Africa’s major cities promote the co-existence of linear alkylbenzene sulfonate (LAS) and other pollutants such as metals. combined effects LAS metals, when water is to irrigate crops, has not been properly investigated light human health risks prevailing local conditions. To understand potential risks, pot-culture ...

A sensitive method based on the fluorescence enhancement was developed for the determination of rutin. It was found that the rutin could form a fluorescent complex with ytterium (III), and the fluorescence intensity of which could be enhanced by sodium dodecyl benzene sulfonate. Under the optimum conditions, the enhanced fluorescence intensity was in proportion to the concentration of rutin in ...

Mesoporous slit-structured NiO materials were prepared through a simple hydrothermal route with sodium dodecyl benzene sulfonate (SDBS) as an additive. The as-prepared NiO samples presented high specific capacitance of over 1700 F g(-1) in the potential range from 0.10 to 0.56 V (vs. Hg/HgO/6 mol L(-1) KOH) at a constant current of 2 A g(-1), and good capacitance retention of ∼90% after 1000 co...

The physical and mechanical properties of mortar containing synthetic cosurfactants as air entraining agent are investigated. The cosurfactants consist of a combination of 2% dodecyl benzene sodium sulfonate (DBSS) and either 1.5% polyvinyl alcohol (PVA) or 1.5% polyoxyethylene glycol monomethyl ether (POE). Also these cosurfactants were used to prepare copolymers latex: styrene/butyl methacryl...
