Theory of resonance energy transfer involving nanocrystals: the role of high multipoles.

Investigating the resonance energy and charge transfer in the clonidine and c60-clonidine-fullerene carriers with quantum chemistry calculations

Clonidine has two aromatic rings in which halogens are attached to one ring in this study, both in drug state and in fullerene nanostructure, and by changing the type of halogen at the * HF / 6-31G level and in The gas phase was first optimized and then the NBO calculations were performed. The results obtained in N61, N63 and N5, N3 indicate the highest rhizanese energy and load transfer that, ...

Chemical Synthesis and Characterization of Perovskite NdfeO3 Nanocrystals via a Co-Precipitation Method

A facile co-precipitation method for the synthesis of well-dispersed NdFeO3 nanocrystals is developed in the presence of octanoic acid as surfactant. Co-precipitation can produce fine, high-purity, stoichiometric particles of single and multicomponent metal oxides. The product is characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microsc...

3-D RF Coil Design Considerations for MRI

High-frequency coils are widely used in medical applications, such as Magnetic Resonance Imaging (MRI) systems. A typical medical MRI includes a local radio frequency transmit/receive coil. This coil is designed for maximum energy transfer or wave transfer through magnetic resonance. Mutual inductance is a dynamic parameter that determines the energy quantity to be transferred wirelessly by ele...

Complete Quenching of CdSe Nanocrystal Photoluminescence by Single Dye Molecules

Much of the current research into semiconductor nanocrystal (NC) photochemistry has focused on their potential application as biological reporters, as light harvesting elements in solar energy conversion systems, or as tunable emitters in light-emitting diodes (LEDs). These applications all necessitate energy or charge-carrier transfer between semiconductor materials and molecular species. For ...
