Fabrication of ceramic micro-scale hollow components by micro-powder injection moulding [PDF]

open access: yes, 2012
Rapid developments in microsystem technologies demand ceramic microcomponents of increasing geometrical complexity. State-of-the-art microfabrication routes of ceramics are either limited in geometrical complexity and/or high volume capabilities. This

Ceramic Keratoprostheses

open access: yesOphthalmology, 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

Self‐Regulated Learning Meets AI: Reinterpreting Self‐Regulation, Co‐Regulation, and Socially Shared Regulation in Human–AI Interaction

open access: yesNew Directions for Adult and Continuing Education, EarlyView.
ABSTRACT Advancing artificial intelligence (AI) has transformed learning and work, yet higher education and professional development programs have not systematically equipped learners for AI‐prevalent environments. This lack of preparation creates uncertainty regarding control, responsibility, trust, and accountability.
