Molecular Mechanism of Viscosity Sensitivity in BODIPY Rotors and Application to Motion-Based Fluorescent Sensors.

ACS Sensors, 2020
Viscosity in the intracellular microenvironment shows a significant difference in various organelles and is closely related to cellular processes. Such microviscosity in live cells is often mapped and quantified with fluorescent molecular rotors.

Helicopter Main-Rotor/Tail-Rotor Interaction

Journal of the American Helicopter Society, 2000
Preliminary results from a study to model the interaction aerodynamics and aeroacoustics of the main and tail rotor of a helicopter in subsonic flow are presented. The configurations studied are: 1) two bladed main and tail rotors in hover, and 2) a four-bladed main rotor and two-bladed tail rotor in climbing flight.

The effects of the aerodynamic interaction on the performance of two Flettner rotors

, 2020
Flettner rotors are nowadays becoming a widespread solution for wind-assisted propulsion. To increase the fuel savings of the ship on which they are installed, multiple devices are typically used.

Self-Assembly of Highly Stable Zirconium (IV) Coordination Cages with Aggregation Induced Emission (AIE) Molecular Rotors for Live-Cell Imaging.

Angewandte Chemie, 2019
Although supramolecular coordination complexes have demonstrated outstanding host-guest chemistry in solution or solid state, the low structural stability, weak fluorescence emission, and cell viability in aqueous solutions have limited their ...

A method to minimize stage-by-stage initial unbalance in the aero engine assembly of multistage rotors

Aerospace Science and Technology, 2019
The paper proposes a method to minimize stage-by-stage initial unbalance in the aero engine assembly of multistage rotors based on the connective assembly model. The process of the mass eccentric deviation propagation in the assembly is analyzed.

The Effects of Rotor-Rotor and Rotor-Wing Interactions on eVTOL Aeroacoustics

Proceedings of the Vertical Flight Society 79th Annual Forum, 2023
This study examines the effect of aerodynamic interactions on a two-rotor pair in cruise, and a propeller acting in the presence of a wing. The two-rotor system with a forward and an aft rotor in-line is considered at different disk loadings (6, 8, 12 lb/ft² for a fixed cruise speed and different cruise speeds (20, 40, 60 knots) for a fixed ...
