We report on measurements of the rate of homogeneous ice nucleation in supercooled water microdroplets levitated in an electrodynamic balance. By comparison of the freezing probability for droplets of radius 49 µm and 19 µm, we are able to conclude that homogeneous freezing is a volume-proportional process and that surface nucleation might only be important, if at all, for much smaller droplets.

In this paper, we review some recent cavity quantum electrodynamic (CQED) experiments with single quantum dot exciton coupled to photonic crystal cavities, performed in our group. We show how the coupled quantumdot/cavity system can be used to modulate light with at a very fundamental level with very low power and discuss some applications of these low power modulators.

Using the Lagrangian that was developed on the corresponding principle between the moving medium electrodynamic and quantum field theory the explicit expression for the static polarizability vertex has been obtained. The applications of this vertex for calculations of real Compton scattering amplitude as well as the imaginary part of doubly virtual Compton scattering amplitude have been demonst...

No. # 121 Determination of Hollow Cathode Plasma Contactor System Requirements using an Electrodynamic Tether System Simulation Tool One application of bare electrodynamic tether systems is to deorbit spent satellites and debris from Low-Earth Orbit. In these systems a hollow cathode plasma contactor sub-system is used to form a plasma bridge between one end of the tether and the space plasma i...

Electrodynamic balance–mass spectrometry allows to study the ozonolysis of linoleic acid under strongly different ozone concentrations and reveals importance autoxidation at low concentrations.

Since entering the new era, economy has grown rapidly and economic strength improved significantly, but it is accompanied by resource environmental problems caused high pollution energy consumption growth model. Realizing transformation of development from “incremental” to “increasing quality” promoting green become one main goals China in next stage. With rapid China’s social economy, changes ...

Three different delivery concepts (standard diffusion, global electrodynamic precipitation, and localized nanolens-based precipitation) and three different SERS enhancement layers (a silver film, a nanolens-based localized silver nanoparticle film, and the standard AgFON) are compared. The nanolens concept is applied to increase the SERS signal: a factor of 633, when compared to a standard mech...

A deorbit device is required for some microsatellites to meet space debris mitigation guidelines, although very challenging in terms of limited resources and reliability. The authors are conducting research on post-mission disposal (PMD) devices using an electrodynamic tether due its high efficiency simplicity. This PMD consists a deployment system, electron emitter, integrated control system. ...

The phase functions of single mineral dust particles levitated in an electrodynamic balance have been measured. Normalized phase functions and the asymmetry parameter could be determined because nearly the full range of scattering angles was available: 0.5° to 177°. The particles have been characterized using microscopy.
