Abstract:
A p-nitrophenyl based rhodamine probe (NPRB) has been designed and synthesized for the selective, real-time detection of Al(iii) in aqueous medium with a lower micromolar range detection limit at physiological pH. All the spectroscopic and theoretical analyses validated the proposed 1 : 1 complexation between NPRB and Al3+ along with an 80-fold enhancement in fluorescence intensity. Using the "turn on" response of the probe, binding of NPRB to Al3+ in the brain tissue of adult male zebrafish (D. rerio) has been visualized through fluorescence microscopy.

Equations of Motion: Rectangular Coordinates and Cylindrical Coordinates
When a particle moves relative to an inertial frame, the equations of motion can be expressed using rectangular components. If the motion is confined to the x-y plane, the equations having the x and y coordinates only can be used to simplify the mathematical representation.
However, when particles...
