Provided is a dental articulator and a dental model fixing pin used for the same. The dental articulator has a base member for molding a dental model for a patient. The base member includes a protrusion bed that is formed on a top face of the base member along a central line in a lengthwise direction of the base member, comes into contact with a plaster dental model placed on the top face of the base member, and has a predetermined height, length, and width. The protrusion bed includes a plurality of pin fixing holes in a middle portion thereof, the plurality of pin fixing holes being spaced apart from one another at regular intervals and passing through an interior of the base member.

Provided is a dental articulator, and more particularly, a dental articulator, in which a tray keeping a shape and dimensions of a dental model is fitted into an upper portion of a base member to which the dental model is coupled. Particularly, the tray coupled to a top surface of the base member is geometrically similar to the base member, and includes a boundary wall formed along an edge thereof at a predetermined thickness and height, a through-hole formed inside the boundary wall, and a pin cap structure that has a plurality of fitting holes into which pins of a pin structure of the base member are fitted and which are continuously formed along an inner central axis of the through-hole and that is connected to opposite inner ends of the boundary wall. Further, each of the arcuate and linear boundary walls of the tray has a plaster anti-overflow flange formed at an upper end thereof and bent in an outward direction to prevent plaster from overflowing down. The front arcuate boundary wall includes tool insertion cages in lower ends of both lateral surfaces thereof which are recessed inwards so that the dental model is easily separated from the base member after being hardened.

A capacitor device with high energy density and high extraction efficiency based on sol-gel films. The films can be formed by use of a single precursor, including siloxane precursors bearing a polar group on a flexible tethering group. The sol-gel compositions used in the formation of films can have high dielectric permittivity, low dielectric loss, high breakdown strength and high-energy storage properties. The forming processing methods described here can be well suited for both high energy density and high power density to provide enhanced energy storage capabilities for discrete, embedded or on-chip integrated capacitor applications, gate dielectrics for transistors and displays, capacitive touch screens, light weight mobile defibrillators, filters for cellular devices, electric propulsion, electric vehicles, power invertors for microgrid storage, load leveling of transients on a wide range of timescales for medium voltage electric grids.
