Efficient Charge Separation in Multidimensional Nanohybrids

Nano Letters, 2011
We report unidirectional charge transfer in multidimensional nanohybrids, consisting of a quantum dot, an electronically active molecular linker, and a carbon nanotube. After covalent attachment to the nanotube, only emission consistent with the negatively charged quantum dot exciton ion rather than the neutral exciton is observed, showing nearly ...

Microchip Devices for High-Efficiency Separations

Analytical Chemistry, 2000
We have fabricated a 25-cm-long spiral-shaped separation channel on a glass microchip with a footprint of only 5 cm x 5 cm. Electrophoretic separation efficiencies for dichlorofluoroscein (DCF) on this chip exceeded 1,000,000 theoretical plates and were achieved in under 46 s at a detection point 22.2 cm from the injection cross.

Separation efficiencies in hydrophilic interaction chromatography

Journal of Chromatography A, 2008
Hydrophilic interaction chromatography (HILIC) is important for the separation of highly polar substances including biologically active compounds, such as pharmaceutical drugs, neurotransmitters, nucleosides, nucleotides, amino acids, peptides, proteins, oligosaccharides, carbohydrates, etc.

Separation of alkaloids using radial chromatography and its separation efficiency

Chinese Journal of Chromatography, 2018
The radial thin layer chromatography (RTLC) is a chromatographic method for the simple, rapid and efficient separation of samples from the center along the radial direction. Simple device was assembled to separate the alkaloids contented in Zhusha Anshen Pills (ZSASP).

Evaluation of Separation Efficiency of a Cyclone-Type Oil Separator

2021
Oil separators play an important role in screw chillers for preventing oil circulation in the system and providing continuous oil return to the compressor crankcase. The present study intends to evaluate the performance of a cyclone-type oil separator for a water-cooled screw chiller having a cooling capacity of 245 TR.

Numerical and experimental study on separation efficiency of steam separators

2010 IEEE International Conference on Mechatronics and Automation, 2010
To improve the separation efficiency of steam and gas in power plant a new type steam separator is presented. A mathematical model is established for simulating the flow field of gas flow channels in steam separator. The gas-water separating efficiency is calculated for the droplets at different particle diameter.

Humidity Effect on the Separation Efficiency of Cylindrical Cyclone Separator

Volume 7: Fluids Engineering Systems and Technologies, 2014
In order to evaluate the humidity effect on the performance of a gas-solid cyclone, an experimental setup is designed including a cylindrical cyclone with a tangential inlet, air compressor, humidifier, flow meter and injector of particles with known properties.

Color‐separating backlight for improved LCD efficiency

Journal of the Society for Information Display, 2008
Abstract— A large part of the light generated in a backlight is usually absorbed in the color filters of the liquid‐crystal display. A new backlight system that uses a grating to split the white light into different colors and a lens array to focus this light onto the pixels is presented.
