Pyronine B adheres to on the surface of CdS and prevents CdS aggregating, which leads to the decrease of fluorescence quantum yield of CdS. Fluorescence resonance energy transfer happens from CdS to Rhodamine B, Butyl rhodamine B and Rhodamine 6G, respectively. There is a higher FRET efficiency between CdS and Neutral red with the value being 0.282. Moreover, coupling reaction between -NH_2 of Neutral red and -COOH of CdS -TGA leads to red shift of CdS fluorescence spectrum. The reaction also occurs between Safranine T and CdS. At the same time, the Fluorescence of ST is quenched by forming ST -CdS ground state complex. Chapter 6, CdS QDs modified by chitosan and polyethyleneimine can be quenched by Cu~(2+). According to the experimental result, we develop the novel sensor for Cu~(2+).
研究结果,吡啰红与CdS之间作用形式是染料聚集在CdS的表面使得CdS不易聚集,但同时也降低了CdS的发光的量子效率;罗丹明B、罗丹明6G、丁基罗丹明B均与CdS之间存在能量转移,位阻效应使得能量转移效率最高的BRhB的相对荧光强度增大最小;中性红与CdS的能量转移效率更高,同时推测可能使CdS-TGA上的-COOH与部分NR的-NH_2发生偶联导致粒子变大而发生荧光光谱的红移;番红花红与CdS是相互荧光猝灭,可能是ST的-NH_2与CdS-TGA上的-COOH发生偶联使得纳米粒子变大以及二者形成基态复合物的共同作用的影响。

Being combining with products distribution in styrene oxidation, we propose the styrene epoxidation carry out with Ti metallacyclo intermediates, And at the same time Ti-ZSM-5 have properties both catalytic epoxidation and acid-catalysis, namely the skeletal Ti can catalyze styrene epoxidation to styrene oxide and the skeletal Ti and Al can provide Lewis acid site to cause the rearrangement of styrene oxide to phenylacetaldehyde rapidly, the solvolysis to glycols and the cleavage of C=C double bond. Ti-ZSM-5 can also provide Bronsted acid site simultaneously, which is also catalytic center for the solvolysis to glycols.

Similarly, if the strong shear, which could suppress all the scattering in the quiescent two phase region, stopped, the follow-up phase separation also displayed characteristics of anisotropism and relaxation, In this dissertation, the transposed"butterfly'and"streakpattern were observed for the first time within the shear-history-influenced phase separation, which is found closely relevant to the anisotropical relaxation behavior of macromolecules. 5. The phase separation kinetics of PS/PVME under oscillatory shear was further studied on the base of that done under simple shear. It is found that, under specific temperature and strain amplitude, the occurrence of phase separation is strongly contingent on oscillatory frequency and only intermediate frequency could effectively induce phase separation; If all considered oscillatory shear could stimulate phase separation, a fixed frequency can maintain specific most probable phase size and higher frequency yields smaller phase, which makes a higher elasticity but weaker stress relaxation; Furthermore, higher frequency can produces stronger compulsory oscillation on the MPPS but won't change the mean of the MPPS. Under given frequency and strain amplitude, the phase separation kinetics dramatically depends on the phase angle of oscillation and the phase separation corresponding to different phase angle follows different dynamical process.
在简单剪切场下相分离动力学研究的基础上进一步对振动剪切场下PS/PVME的相分离动力力学进行了尝试性的研究,发现:在一定温度和振幅条件下,相分离的发生强烈的依赖于振动频率,只有中等频率的振动剪切才能有效地促进相分离的发生;在都能使相分离发生的前提下,一定频率的剪切能够使体系维持一定的最可几相尺寸,较高频率的剪切导致体系形成的相区尺寸较小,因而体系的弹性效应较强而应力松弛效应较弱;同时,更高频率的剪切对最可几相尺寸的强迫振动效应越强,但不会使最可几相尺寸的平均值发生改变;在一定的振幅和频率条件下,相分离的动力学过程会强烈地依赖于相位角,不同相位角对应的相分离遵循不同的动力学过程但机理一样。
