The emulsion polymerization of styrene(St) adsolubilized on the surfactant adsorbed bilayer was carried out by initiator potassium persulfate(KPS). The UV-Vis and surface photovoltage spectra(SPS) indicate that the FeO particles were encapsulated in polystyrene(PSt) successfully.doi:10.1248/cpb.50.307...
The applications ofUV-visible spectroscopyare generally concerned withUV light(200–400nm) and visible light (400–800nm). UV-Vis spectra have been used to be essential characterization for the detection of synthesized CuNPs because the peak position shape of the spectra depends on particle size....

TowerA ClearView db Photometer was installed at a Styrene production tower to monitor the concentration of styrene in ethylbenzene in the presence of toluene and benzene. The MLR calibration for styrene in 10 overhead samples resulted in an (R2>.9999) with a standard error of 0.84% styr...
aggregation state of AuNRs in living cells was of great significance. AuNRs had two distinctive absorption bands in their absorption spectra; the one around 520 nm was called transverse surface plasmon resonance (TSPR) band and the other one which could ...
The similar diffraction angles of the CO32- anion-containing Zn-Al-LDH (Zn-Al-CO32--LDH) and the Zn-Al-CO32--LDH/styrene-butadiene-styrene (SBS) modified asphalt implied that the asphalt molecules do not enter into the LDH interlayer galleries to form separated-phase structures. The ...

Thus the surfactant bilayer was formed on the surface of Fe_2O_3. The emulsion polymerization of styrene(St) adsolubilized on the surfactant adsorbed bilayer was carried out by initiator potassium persulfate(KPS). The UV-Vis and surface photovoltage spectra(SPS) indicate that the Fe_2O_3 ...
UV-Vis spectra show the macromolecular chain has no obvious effect on the maximal absorption of benzophenone moieties. 紫外光谱证实了高分子的结构对二苯甲酮单元的最大紫外吸收几乎没有影响。 lib.cqvip.com 4. The recognition and sensing properties of these receptors were studied by the cyclic voltamme...
Using 9-bromofluorene as an initiator, the atom transfer radical polymerization of styrene was well controlled. The polydispersity index of the resulting polymers is less than 1.15. The UV-vis spectra of the fluorene-labeled polystyrene demonstrated a red shift from a fluorene standard. The ...
