近日,中国地质大学资源学院陈红汉教授团队平宏伟教授在国际顶级石油地质期刊《AAPG Bulletin》上刊发研究成果,利用荧光光谱约束的单一期次油包裹体分子成分分析技术,结合烃源岩生排烃过程荧光演化模型,建立了东营凹陷油包裹体荧光颜色与其热成熟度的定量关系,实现了利用油包裹体荧光特征对单个油包裹体热成熟度的定量预测。
Estimating gross primary productivity (GPP) at large spatial scales is important for studying the global carbon cycle and global climate change. In this study, the relationship between solar-induced c...
Rice University scientists have effectively quenched a debate over the mechanism behind a fluorescent biosensor that monitors neurons by sensing changes in voltage.The work led by Rice theoretical che...
Yellow fluorescent protein (YFP) is widely used as a genetically encoded fluorescent marker in biology. In the course of a comprehensive study of this protein, we observed an unusual, negative fluores...
Surface-generated structured illumination microscopies interrogate the position of fluorescently labeled objects near surfaces with nanometer resolution along the z axis. However, these techniques are...
Green fluorescent proteins bearing the Y66H mutation exhibit strongly blue-shifted fluorescence excitation and emission spectra. However, these blue fluorescent proteins (BFPs) have lower quantum yiel...
Fluorescence interference contrast microscopy (FLIC) is a powerful method to structurally characterize fluorescent objects with nanometer-scale resolution in the z direction. Here we use FLIC to chara...
We have developed a single vesicle assay to study the mechanisms of supported bilayer formation. Fluorescently labeled, unilamellar vesicles (30-100 nm diameter) were first adsorbed to a quartz surfac...
Total internal reflection fluorescence microscopy is widely used to confine the excitation of a complex fluorescent sample very close to the material on which it is supported. By working with high ref...
The spontaneous fluorescence from the special pair primary electron donor in bacterial photosynthetic reaction centers has been measured at low temperature using fluorescence up-conversion following e...
Delayed fluorescence is observed from quinone-depleted Rhodobacter sphaeroides reaction centers due to re-formation of the excited state of the special pair electron donor from the initially formed ra...
The fluorescence intensity from randomly oriented, immobilized Rb. sphaeroides reaction centers at 77 K increases in the presence of an externally applied electric field. We have proposed that this in...
The fluorescence intensity from randomly oriented Rhodobacter ( Rb.) sphaeroides photosynthetic reaction centers at 77 K increases in an applied electric field. This is ascribed to a net reduction in ...
Polyglutamine-expanded huntingtin, the protein encoded by HTT mutations associated with Huntington's disease, forms aggregate species in vitro and in vivo. Elucidation of the mechanism of growth of fi...
