Evaluation of asphaltene degradation on highly ordered TiO2 nanotubular arrays via variations in wettability.

Langmuir : the ACS journal of surfaces and colloids

Tang X, Li D.
PMID: 21192690
Langmuir. 2011 Feb 01;27(3):1218-23. doi: 10.1021/la104203f. Epub 2010 Dec 30.

Photocatalytic degradation of both aquatic and atmospheric organic pollutants on titanium dioxide has been extensively investigated in the past decades, but research on direct photocatalytic degradation of solid-phase organic pollutants is rather limited. In this work, photocatalytic degradation of...

PS colloidal particles stabilized by graphene oxide.

J Nanosci Nanotechnol. 2010 Sep;10(9):5935-50. doi: 10.1166/jnn.2010.2558.

Materials characterization at the nano-scale is motivated by the desire to resolve the structural aspects and deformation behavior at length scales relevant to those mechanisms that define the novel and unusual properties of nano-structured materials. A range of novel...

Microfluidic fabrication of porous polymer microspheres: dual reactions in single droplets.

Langmuir : the ACS journal of surfaces and colloids

Gong X, Wen W, Sheng P.
PMID: 19402604
Langmuir. 2009 Jun 16;25(12):7072-7. doi: 10.1021/la900120c.

We report the microfluidic fabrication of macroporous polymer microspheres via the simultaneous reactions within single droplets, induced by UV irradiation. The aqueous phase of the reaction is the decomposition of H(2)O(2) to yield oxygen, whereas the organic phase is...

Quantum path interferences of electron trajectories in two-center molecules.

Yang W, Song X, Zeng Z, Li R, Xu Z.
PMID: 20174084
Opt Express. 2010 Feb 01;18(3):2558-65. doi: 10.1364/OE.18.002558.

We report a new quantum path interference effect of electron trajectories in high-order harmonic generation (HHG) from two-center molecules, in which the interference minima are mainly located in the high-energy portion of HHG spectrum. The quantum calculations of the...

Impact of the tissue factor pathway inhibitor gene on apoptosis in human vascular smooth muscle cells.

Genetics and molecular biology

Dong X, Song LP, Zhu DW, Zhang HL, Liu LX, Leng XG.
PMID: 21637538
Genet Mol Biol. 2011 Jan;34(1):25-30. doi: 10.1590/S1415-47572011000100005. Epub 2011 Mar 01.

Tissue factor pathway inhibitor (TFPI) plays a vitally important role in the blood coagulation pathway. Recent studies indicated that TFPI induces apoptosis in vascular smooth-muscle cells (VSMCs) in animals. The present study investigated whether the TFPI gene could also...

New for old. Password to the thermodynamics of the protic ionic liquids.

Physical chemistry chemical physics : PCCP

Verevkin SP, Zaitsau DH, Tong B, Welz-Biermann U.
PMID: 21695350
Phys Chem Chem Phys. 2011 Jul 28;13(28):12708-11. doi: 10.1039/c1cp20679f. Epub 2011 Jun 22.

Activity coefficients at infinite dilution of some common solvents in a protic ionic liquid ethylammonium nitrate have been measured using well established gas-chromatography-method. This method was possible to apply due to extremely low vapour pressure of ethylammonium nitrate at...

Circularly-polarized laser-assisted photoionization spectra of argon for attosecond pulse measurements.

Optics express
