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...

Bilayer actuators of gold and polypyrrole doped with dodecylbenzenesulfonate, PPy(DBS), were microfabricated with lengths and thicknesses that varied over two orders of magnitude. The actuators were connected to rigid plates. The curvature of the bilayers was examined as a function of PPy and Au layer thicknesses to enable a determination of the actuation strain and Young’s modulus of the PPy(D...

This study assessed the efficacy for removing Cryptosporidium parvum oocysts of poorly sorted, Fe- and Al-rich, subsurface sediments collected from 0.9 to 4.9 and 1.7-13.9 m below land surface at an operating riverbank filtration (RBF) site (Russian River, Sonoma County, CA). Both formaldehyde-killed oocysts and oocyst-sized (3 microm) microspheres were employed in sediment-packed flow-through ...

In this paper, we demonstrate the controlled capture and release of dichloromethane (DCM) droplets on dodecylbenzenesulfonate-doped polypyrrole (PPy(DBS)) surfaces in an aqueous environment. The droplets captured on oxidized PPy(DBS) surfaces were released on-demand via a reduction process at ∼0.9 V, with controlled release time and droplet morphology. The release time of an entire droplet (2 ±...

The low flow characteristics of heavy oil have brought many challenges to its exploitation. Looking for a cost-effective crude improver reduce the viscosity is currently most important challenge. Small-molecule improvers meet above requirements and become an ideal target oilfield production. In this article, three kinds barium salts alkylbenzene sulfonates with different lengths alkyl chains we...
