Real-time fluorescence visualization of slow tautomerization of single free-base phthalocyanines under ambient conditions.
نویسندگان
چکیده
The emission transition dipole moments of single-molecule free-base phthalocyanines at an air/glass interface were visualized using defocused wide-field fluorescence microscopy at a temporal resolution of 100-200 ms. Isolated molecules showed slow proton tautomerization, which is consistent with previous theoretical calculations in the gas phase, which predicted large activation energies.

Attentional Demands of Balance Under Dual Task Conditions in Young Adults
Objectives: The aim of this study was to identify the role of attentional process in postural control using choice reaction time task while changing the visual and proprioceptive cues under difficult balance task (standing on one-leg). Methods: This cross-sectional study was conducted by participating 20 young people (22.75±2.29). Each subject performed one-leg standing as balance task for e...

One of the most widely used propellants is nitrocellulose (NC) based on propellant, which is divided into three general groups including single base propellant (SBP), double base propellant (DBP), and triple base propellant (TBP). In this paper, the life time of three types of NC-based propellants has been examined by using the vacuum stability test (VST). In this method, kinetic equations have...
متن کاملFlow Visualization by Conditional Sampling of a Single X-Wire Probe in a Very Long Run Experiment
Flow visualization techniques using tracer markers such as die, smoke, hydrogen bubbles, etc., have been widely used in experimental investigations of large scale structures of a variety of flow fields. They have played an important role in understanding the physics of the coherent structures' formation and evolution in the transitional as well as the turbulent regions of the flow fields. Howev...

متن کاملThe zinc chromium ferrite magnetic nanoparticles ZnCrFeO4: An efficient catalyst for acetylation of alcohols, phenols and amines under solvent-free conditions
In this study, the zinc chromium ferrite magnetic nanoparticles ZnCrFeO4 are synthesized via sol-gel method and characterized by X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The XRD analysis showed that ZnCrFeO4 has single-phase cubic structure. The synthesized ZnCrFeO4 has been used as an efficient catalyst for acetyl...
