Cryogenic Engineering

Development of cryogenic prototyping for tissue engineering

A major challenge in tissue engineering has been the creation of scaffolds with controlled complex geometries. Rapid prototyping (RP) has the ability to produce complex threedimensional structures with precise control of pore size, geometry and connectivity. In this paper, a novel technique utilising RP technology for the fabrication of tissue engineering scaffolds is presented. The main advant...

Cartilage tissue engineering using cryogenic chondrocytes.

OBJECTIVE To generate in vitro hyaline cartilage from cryogenically preserved human septal chondrocytes in a simulated microgravity environment on a 3-dimensional biodegradable scaffolding material. METHODS In this experiment, cryogenically frozen chondrocytes were thawed and cultured in a monolayer in serum-based chondrocyte media. They were seeded onto 3-dimensional biopolymer scaffolds in ...

Receiver Cryogenic System

Cryogenic Model Materials

An overview and status of current activities seeking alternatives to 200 grade 18Ni Steel CVM alloy for cryogenic wind tunnel models is presented. Specific improvements in material selection have been researched including availability, strength, fracture toughness and potential for use in transonic wind tunnel testing. Potential benefits from utilizing damage tolerant life-prediction methods, r...

A Cryogenic Data

A computer storage system which is addressed by content rather than location is described. The design has been verified by constructing and successfully operating a three-word module consisti~g of 81 crossed-film cryotrons on a 6-inch by 3-inch substrate.
