Free-Space Concentration of Diffused Light
OSA Advanced Photonics Congress (AP) 2020 (IPR, NP, NOMA, Networks, PVLED, PSC, SPPCom, SOF), 2020We present a new strategy to concentrate diffused light in free space based on luminophore doped waveguides with nanophotonic surface control. Waveguides are designed to allow for escape under a specific escape cone.

The category RoTop of topological Ro-spaces and continuous maps can be embedded as a nice subcategory into Near, the category of nearness spaces and nearness preserving maps. The resulting subcategory TNear of Near has the property that products and subspaces of TNear-objects taken in Near are generally different from those taken in TNear.

Solar concentrator for space power generation
23rd Aerospace Sciences Meeting, 1985A solar collector of Cassegrainian type, designed to collect over 1000 kilowatts of solar energy, is presented. When combined with energy storage, a dynamic energy conversion cycle, and a liquid droplet radiator for heat rejection, the system has great potential for space station applications.

23.5% thin-film space concentrator cells
IEEE Conference on Photovoltaic Specialists, 2002Thin-film AlGaAs-GaAs double-heterostructure concentrator cells were fabricated which exhibit total-area conversion efficiencies as high as 23.5% AM0 at 100 suns, 25 degrees C. This is one of the best space concentrators measured to date at NASA and is designed for a thin-film cell without a prismatic coverglass. This solar cell structure consists of a

Solar concentrators for space processing applications
10th Thermophysics Conference, 1975A study on the technological feasibility of using solar concentrators for crystal growth and zone refining in space has been performed. Previous studies related to the many aspects of the problem are reviewed. It was concluded from this effort that the technology for fabricating, orbiting, and deploying large solar concentrators has been developed.

Dynamics of extended space charge in concentration polarization
Physical Review E, 2010This paper is concerned with ionic currents from an electrolyte solution into a charge selective solid, such as an electrode, an ion exchange membrane or an array of nanochannels in a microfluidic system. All systems of this kind have characteristic voltage-current curves with segments in which current nearly saturates at some plateau values due to ...

Factors affecting airborne beryllium concentrations in dental spaces
The Journal of Prosthetic Dentistry, 1975Air sampling for beryllium concentrations produced during finishing procedures for a beryllium-containing alloy was conducted in two rooms with capacities of 700 and 10,000 cubic feet. The clearance rate of beryllium in the air and the effect of ventilation and room size on these concentrations were investigated.

New concentration inequalities in product spaces
Inventiones Mathematicae, 1996We consider that this paper is particularly rich in results, methods, comments explaining the results, outlines of history, accompanied by quotation of expository papers. In order not to increase the length of the review (author's abstract would be a too short one), we present only the results entitled as theorems. Let \((\Omega,\mu)\) be a probability
