Influences of Triton X-100 on Hemoglobin Behaviors in Hemoglobin/Acyclovir/Triton X-100/H2O System

The influences of Triton X-100 on hemoglobin （Hb） behaviors were studied by the methods of UV-Vis spectrum, fluorescence spectrum, HPLC, conductivity, zeta potential and negative-staining transmission electron microscope in Hb/acyclovir/Triton X-100/H2O system. With the increase of Triton X-100 concentration in the system, the percentage of the free acyclovir increased from 58%--63% to 90%--94%. The static quenching constant and the association number of acyclovir to Hb decreased. The fluorescence spectrum, conductivity, zeta potential, fluorescence polarization and negative-staining morphology of Hb tended to recover to those of the original state of Hb in the same concentration of Hb. The interaction between Triton X-100 and Hb is stronger than that between acyclovir and Hb. Most Triton-X-100 was associated with Hb at low Triton X-100 concentration. But the interaction of Triton X-100 with Hb was apparently dominant in high Triton X-100 concentration. The Hb structure was unfolded and finally denatured.     

四磺化酞菁钴在微乳液、醇-水体系中的二聚现象研究

采用分光光度法研究了四磺化酞菁钴（ＣｏＴＳＰｃ），在微乳液（ＴｒｉｔｏｎＸ－１００－壬烷－正戊醇－水）、醇－水（甲醇、乙醇、丙醇）体系中的二聚现象，计算了ＣｏＴＳＰｃ的二聚常数ＫＤ。结果表明，ＣｏＴＳＰｃ的二聚常数ＫＤ值随着微乳液中表面活性的浓度及醇－水溶液的介电常数的增加而减小。     

醇对非离子型表面活性剂浊点的影响

研究了醇对非离子型表面活性剂浊点的影响，发现直链醇的碳原子数小于４时随着其在表面活性剂中含量的增加浊点上升；当碳原子数大于４时，则随着醇含量的增加浊点下降。醇的构型对浊点起着重要作用。     

微乳液的微观结构

由于超低界面张力的发现，对传统的微乳液结构认识带平冲击，统计力学模型的建立不应局限于经典的物理图象，应更广泛地考虑界面上各种效应，一些原认为次要因素却成为重要因素，诸如；弯面压力，混合熵，范德华引力等。     

非水层状液晶的稳定性与相行为

水体系层状液晶已研究较久,非水层状液晶则是近十年来才得到发展。本文以层状液晶的相行为和~2H NMR测量,研究并比较了非水层状液晶十二烷基硫酸钠/正癸醇溶剂以甘油或甲酰胺为溶剂时体系的结构与稳定性。 表面活性剂十二烷基硫酸钠(BDH,简写SDS)经无水乙醇重结晶两次提纯。用铂环法测     

SDS/n－C5H11OH/n－C7H16/H2O体系中W/O－BI微乳液界面电性质

In the system of SDS/n-C5H11OH/n-C7H16/H2O with the weight ratio of SDS/n-C5H11OH/H2O system at5.0/47.5/47.5, the upper phase of the system was W/O microemulsion, and the lower phase was the bicontinuous microemulsion. When the n-heptane content was less than 1%, with the increase of the n-heptane content, the capacitance (Co, Cod) in the upper phase (W/O) dropped, the capacitance (CB1, CBld) in the lower phase (BI) raised. At the same time, the W/O-BI inteffacial potential (ΔE), capacitance (Ci), and charge-transfer current (ict) decreased.After the n-heptane content reached 1%, with the increase of the n-heptane content, ΔE, Ci and ict demonstrated no significant change.
