In the beginning, before the printing press, printmaking was not considered an art form, but rather a form of communication. It was not till the 18th century that art prints began to be considered originals and not till the 19th that artists began to produce limited editions and to sign their prints along with the technical information necessary to authenticate the work.. of 3D . structures on the micrometer . scale.

Abstract. . Microelectromechanical Systems (MEMS) are devices that integrate mechanical systems with electronic circuits. Fabrication of MEMS involves the use of specialized micromachining technologies. Device packaging aims to protect from outside damage and varies drastically depending upon application. Different materials used, fabrication techniques, and packaging types will be examined.. Abstract:. MEMS . technology consists of microelectronic elements, actuators, sensors, and mechanical structures built onto a substrate, which is usually silicon. They are developed using microfabrication techniques: deposition, patterning, and etching. The most common forms of production for MEMS are bulk micromachining, surface micromachining, and HAR fabrication. Igor Ozerov / PLANETE . / . Aix-Marseille . Univ. , CNRS, CINAM 13009 .

Certain phenomenological models have raised the possibility of the existence of a new kind of matter called Strange Quark Matter (SQM), containing nearly equal numbers of up, down and strange quarks, the discovery of which will be of huge significance for physics..
