TL;DR: In this paper, the alumina-silica phase relations of samples annealed in oxygen and quenched were studied by optical microscopy, image analysis, X-ray diffraction, and the electron microprobe.
Abstract: The alumina-silica phase relations of samples annealed in oxygen and quenched were studied by optical microscopy, image analysis, X-ray diffraction, and the electron microprobe. The solid solution boundaries of mullite changed with increasing temperature and joined at 1890°C and a composition of 77.15 wt% alumina. The melting point of mullite was 189°C with a peritectic between 76.5 and 77.0 wi% alumina.

TL;DR: An immobilized film of an aqueous bicarbonate-carbonate solution was developed which was 4100 times more permeable to carbon dioxide than to oxygen and could be increased by addition to the film of catalysts for the hydrolysis of carbon dioxide.
Abstract: An immobilized film of an aqueous bicarbonate-carbonate solution was developed which was 4100 times more permeable to carbon dioxide than to oxygen. The carbon dioxide transport was reaction-rate limited, and thus it could be increased by addition to the film of catalysts for the hydrolysis of carbon dioxide.

TL;DR: In this paper, the principal features of polycrystalline CdTe solar cells and their method of fabrication are described, and the junction is interpreted as a heterojunction between p-type copper and n-type cadmium telluride, the transition region extending well into the cdTe side.
Abstract: This paper describes the principal features of polycrystalline CdTe solar cells and their method of fabrication. These cells are prepared such that a p-type copper telluride surface film is an integral part of the photovoltaic junction. Some description is also given of single-crystal cells where the junction is fabricated similarly to that of the films. Solar conversion efficiencies up to 6 per cent have been obtained in film cells, and 7 1/2 per cent for single-crystal ones. The junction is interpreted as a heterojunction between p-type copper telluride and n-type cadmium telluride, the transition region extending well into the CdTe side. The copper telluride film plays a minor part in the absorption of radiation for the production of electron-hole pairs. The method of fabrication, experimental results, and present interpretation are compared to that existing for other CdTe and CdS solar cells.

TL;DR: In this paper, the losses in a Class-D RF switching power amplifier and their frequency dependence are described and a new low inductance half-bridge package is introduced to solve this problem.
Abstract: In this paper, the losses in a Class-D RF switching power amplifier and their frequency dependence are described. The losses analyzed are the switching, conduction, and gate drive losses. A 300 W, 13.56 MHz, Class-D circuit is designed in the traditional manner to illustrate the magnitude of the different types of loss. A circuit using the ZVS equations developed in this paper is designed. An experimental circuit is built using standard IRF540 devices in TO220 packages. That circuit does not meet its performance goals because of the package inductance. A new low inductance half-bridge package is introduced to solve this problem. Techniques for circuit layout and power measurements for RF applications are also presented in the experimental section. A low loss gate drive circuit is also presented using a Class-E circuit to provide the drive power. The experimental results confirm the accuracy of the design equations derived in this paper. >
