Journal of environmental radioactivity, 116, 141-147 (2012-11-17)
The use of a carboxylate-functionalized graft copolymer (PGTDC-COOH) based on titanium dioxide-densified cellulose (TDC) for the removal and recovery of thorium(IV) [Th(IV)] from industrial wastewater is reported in this paper. Infrared spectroscopy and X-ray diffractometer were used to characterize the

Journal of chromatography. A, 1270, 162-170 (2012-11-28)
We introduce a chromatography method for purification of large proteins and viruses that works by capturing them at a non-reactive hydrophilic surface by their mutual steric exclusion of polyethylene glycol (PEG). No direct chemical interaction between the surface and the

The cladding air channels of an endlessly single-mode photonic crystal fiber (PCF) and the high-index sensitivity of its long-period gratings (LPG) inscribed by CO(2) laser have been exploited to deposit poly(vinyl pyrrolidone) (PVPON)/poly(methacrylic acid) (PMAA) polyelectrolyte thin films via layer-by-layer
Caihong Zhou et al.
The Analyst, 137(19), 4469-4474 (2012-08-08)
An inverse opal photonic crystal sensor that could specifically detect chloramphenicol (CAP) in a label-free way was introduced in the current research. A colloidal crystal template was first prepared from monodisperse SiO(2) nanospheres. Precursors with different compositions were infused into
