Ceramic Keratoprostheses

Ophthalmology, 1980
This paper describes a new type of corneal prosthesis made of aluminum oxide ceramic. The implant consists of a retaining plate with a 3-mm central performation to which an optical cylinder is threaded. The cylinder also made of ceramic material, has a high refractive index and 60 diopters of power. Experimental study has shown that soft tissue adheres

Thermal-inert and ohmic-contact interface for high performance half-Heusler based thermoelectric generator

Nature Communications, 2022
Unsatisfied electrode bonding in half-Heusler devices limits their practical service at high temperatures. Here, the authors develop a direct bonding interface to ideal ohmic contact and thermally inert and ohmic contact, leading to high deficiency.

Dual fluorination of polymer electrolyte and conversion-type cathode for high-capacity all-solid-state lithium metal batteries

Nature Communications, 2022
The practical use of all-solid-state batteries is hindered by inadequate cycling performance. Here, the authors propose a fluorination strategy for the positive electrode and polymeric electrolyte to develop all-solid-state Li||FeF3 pouch cells with high

Composition and luminescence properties of highly robust green-emitting LuAG:Ce/Al2O3 composite phosphor ceramics for high-power solid-state lighting

Journal of Advanced Ceramics, 2023
The major advantage of laser lighting over white light-emitting-diode is the possibility to achieve ultra-high luminance. However, phosphors usually suffer laser-induced luminescence saturation, which limits the peak luminance of laser lighting devices ...

Structure and electrical properties of single-phase cobalt manganese oxide spinels Mn3xCoxO4 sintered classically and by spark plasma sintering(SPS) [PDF]

, 2009
Cobalt manganese oxide spinels Mn3 xCoxO4 (with 0.98pxp3) were prepared by the thermal decomposition in air of oxalate precursors. The influence of the thermal treatments on the structure of these materials is emphasized.
