Precise control of an individual particle or molecule is a difficult task. Controlling multiple particles simultaneously is an even more challenging endeavor. Researchers at the University of Illinois...
Kinetically Trapping Co-continuous Morphologies in Polymer Blends and Composites
co-continuous structure phase separation polymer blend
2014/11/21
Co-continuous structures generated from the phase separation of polymer blends present many opportunities for practical application. Due to the large interfacial area in such structures and the incomp...
We consider light trapping in photonic crystals in the weak material absorption limit. Using a rigorous electromagnetic approach, we show that the upper bound on the angle-integrated absorption enhanc...

Nanophotonic light-trapping theory solar cells
2015/8/10
Conventional light-trapping theory, based on a ray-optics approach, was developed for standard thick photovoltaic cells. The classical theory established an upper limit for possible absorption enhance...
Fundamental limit of light trapping in grating structures
Solar Energy Nanophotonics and photonic crystals Diffraction and gratings
2015/8/10
We use a rigorous electromagnetic approach to analyze the fundamental limit of light-trapping enhancement in grating structures. This limit can exceed the bulk limit of 4n2, but has significant angula...

2009/6/12
We tested a hypothesis that water ejection takes place in the secretory cell. A micro bead was held at about 1μm distant from the cell surface by laser trapping with a 1064 nm light, and the position ...
The trapping of foreign gas molecules (atoms) by growing aerosol particles as well as by already
formed particles is considered. The trapping coefficients are obtained for both above-mentioned cases....
Hygroscopic behaviour modelling of syntactic foams in the presence of trapping and diffuse interfaces
Syntactic foams diffusion interfaces
