An accurate method of the fluorescence probe approach based on an aggregation-induced emission (AIE) molecule (tetraphenylethylene) for measuring the solubility parameter of the polymer is reported. This method is distinctive in that the approach can make the polymer chain conformation in solution be related to the fluorescence intensity. Since the solubility parameter of the polymer is also cl...

the surface parameter of nanoparticles such as hydrophobicity and a hydrophilicity on protein structure and function is very important. in this study, conformational changes of glucose oxidase (gox) in the mercaptopurine: gnps and 11-mercaptoundecanoic acid: gnps as a hydrophobic and a hydrophilic gnps surface was investigated by various spectroscopic techniques, including: uv-vis absorption, f...

Wood structure and wood anatomy are usually considered to be largely independent of the physiological processes that govern tree growth. This paper reports a statistical relationship between leaf and bark chlorophyll fluorescence and wood density. A relationship between leaf and bark chlorophyll fluorescence and the quantity of wood decay in a tree is also described. There was a statistically s...

Chlorophyll-a fluorescence adalah perpendaran cahaya yang dilepaskan oleh klorofil untuk membuang kelebihan energi foton diterima dari sinar matahari pada proses fotosintesa. Salah satu parameter turunan chlorophyll-a Performance Index (PI). PI menggambarkan informasi kualitatif mengenai kebugaran tanaman. Pengamatan saat kondisi normal, tercekam kekeringan moderat, dan parah memungkinkan pengh...

Microsomal membranes from rat liver and from the fast-growing Morris hepatoma 3942A have been peroxidized to different extents and the order parameter of the membranes measured by fluorescence depolarization of the probe 1,6-diphenyl-1,3,5-hexatriene. The data have been analysed by applying a mathematical approach that takes into account simultaneously static and dynamic fluorescence parameters...
