Nitrogen/sulfur co-doped anatase TiO2 nanocrystals with a high specific surface area and a high percentage of {001} facets were synthesized by a solvent-thermal process followed by the calcination with thiourea at an optimum heat treatment temperature.
In summary, nitrogen/sulfur co-doped anatase TiO2 nanocrystals with a high specific surface area and a high percentage of {001} facets were successfully synthesized by a solvent-thermal process followed by the calcination with thiourea at an optimized heat treatment temperature.
For whole-mount in situ hybridization, PTU (1-phenyl 2-thiourea) at a final concentration of 0.003% was added to prevent melanogenesis.
Pd II) was retained on the column at pH 1.0 and quantitatively eluted by 2.5 mL of 0.01 mol L−1 HCl 3%% thiourea solution at a flow rate of 2.0 mL min−1 [3].
The development of endogenous pigments was inhibited by exposing embryos to 1-phenyl-2-thiourea (PTU) at a final concentration of 0.2 mM.
Whole mount in situ hybridizations were performed as previously described.[56] The development of endogenous pigments was inhibited by supplementing the embryo medium with 1-phenyl-2-thiourea (PTU) at a final concentration of 0.2 mM.
The development of endogenous pigments was inhibited by exposing embryos to 1-phenyl-2-thiourea (PTU) at a final concentration of 0.2 mM.
When the amount of MnSO4·H2O was further increased to 0.21 g with a correspondingly increase in that of thiourea at 210°C, the product had several morphologies including core-shell, hollow spheres and a small quantity of polyhedron, shown in Figure 6d (see Figure S1d for the XRD patterns in additional file 1).
Figure 1 SEM micrographs from the surface and cross-sectional views (in inset) of ZnO samples deposited using ZnCl2 solutions: (a) without and (b) containing thiourea at Zn:tu molar ratio of 1 0.25; [Zn2+] = 0.05 mol/L.
After being calcinated with thiourea at 300°C, the specific surface area of T3 showed only a moderate decrease to approximately 70 m2/g.
