Refraction-Assisted Solar Thermoelectric Generator based on Phase-Change Lens
Solar thermoelectric generators (STEGs), which are used for various applications, (particularly small size electronic devices), have optical concentration systems for high energy conversion efficiency. In this study, a refraction-assisted STEG (R-STEG) is designed based on phase-change materials. As the phase-change material (PCM) changes phase from solid to liquid, its refractive index and tra...
متن کاملA note on a possible relation between refraction and a disposition for senile nuclear cataract.
A study was made of records of patients who have had at least 1 senile cataract removed and for whom refraction records were available. The risk of a cataract occurring was determined as a function of precataractous refraction. Emmetropia was found to provide a sharp borderline between the low risk (about 1:1000) of hypermetropes and an increasing risk (about 1:100) for moderate myopes for pati...
متن کاملHints on Refraction
This is an excellent little guide to sight testing by Dr. S. K. G-anguly, Assistant at the Eye Infirmary of the Medical College, Calcutta. It is a very practical little book?concise, correct, and clear. Each section or chapter is devoted to description with methods of procedure and illustrative examples. The difficult subject of astigmatism is clearly explained, and the methods for correction d...
متن کاملEffect of TiO2 Nanofiber Density on Organic-Inorganic Based Hybrid Solar Cells (RESEARCH NOTE)
Abstract In this work, a comparative study of hybrid solar cells based on P3HT and TiO2 nanofibers was accomplished. Electrospinning, a low cost production method for large area nanofibrous films, was employed to fabricate the organic-inorganic hybrid solar cells based on poly (3-hexylthiophene) and TiO2 nanofibers. The performance of the hybrid solar cells was analyzed for four density levels ...
متن کاملSteiger on refraction: a reappraisal.
Seventy years ago Steiger, a Swiss ophthalmologist, found the distribution of corneal powers to follow a normal (binomial) curve. He noted a wide range of values among emmetropes, and he also knew that their axial lengths varied significantly. He expected that normal distributions would be found for other components of refraction and also for refraction as a whole, and in seeking a controlling ...
