Thin-film magnesium as a sacrificial and biodegradable material

2014 IEEE 27th International Conference on Micro Electro Mechanical Systems (MEMS), 2014
This work reports the study of ebeam-deposited thin-film magnesium (Mg) as a sacrificial and a biodegradable material. We have tested etchants including diluted hydrochloric acid (HCl), saline, and culture medium. Both vertical etching method and channel undercut method are used to characterize the Mg etching properties.

Fabrication of microchannels using polycarbonates as sacrificial materials

Journal of Micromechanics and Microengineering, 2001
The use of polycarbonates as thermally decomposable, sacrificial materials for the formation of microchannels is presented. Polycarbonates decompose in the temperature range of 200-300 °C. Two polycarbonates, polyethylene carbonate and polypropylene carbonate, have been used to fabricate microchannels in three different types of encapsulants: an ...

Biofabrication of valentine-shaped heart with a composite hydrogel and sacrificial material

Materials Science and Engineering: C, 2020
3D bioprinting represents a potential solution for organs regeneration, however, the production of complex tissues and organs that are in large size, randomly shaped, hollow, and contain integrated pre-vascularization still faces multiple challenges. This study aimed to test the feasibility of our 3D printing scheme for the manufacturing of micro-fluid

Porous Silicon as a Sacrificial Material for Microstructures Fabrication

MRS Proceedings, 1999
AbstractPorous silicon (PS) is generated by electrochemical etching in hydrofluoric acid (HF). Recently porous silicon has been applied to micromachining and micro-devices as an alternate material, this material being used as a sacrificial layer. This technology competes with conventional techniques like surface and bulk micromachining regarding its ...

Tritium Contamination Prevention Using Sacrificial Materials

Fusion Science and Technology, 2017
AbstractTritium is produced by irradiating Tritium Producing Burnable Absorber Rods (TPBARs) in a Commercial Light Water Reactor at the Tennessee Valley Authority Watts Bar Reactor 1. The TPBARs are manufactured with strict materials specification for contaminants for all of the components.

Development of Freeze-Form Extrusion Fabrication With Use of Sacrificial Material

Journal of Manufacturing Science and Engineering, 2014
The development of freeze-form extrusion fabrication (FEF) process to fabricate three-dimensional (3D) ceramic parts with use of sacrificial material to build support sections during the fabrication process is presented in this paper. FEF is an environmentally friendly, additive manufacturing (AM) process that builds 3D parts in a freezing environment ...

New sacrificial material for ex-vessel core catcher

Journal of Nuclear Materials, 2015
Abstract A new functional (sacrificial) material has been developed in the Fe 2 O 3 –SrO–Al 2 O 3 –CaO system based on strontium hexaferrite ceramic in concrete matrix. The method of producing SM has been advanced technologically; this technological effectiveness allows the SM to be used in ex-vessel core catchers with corium spreading as well as in ...

Lithographic Characteristics and Thermal Processing of Photosensitive Sacrificial Materials

Journal of The Electrochemical Society, 2002
Previously, a novel method for fabricating microfluidic and microelectromechanical devices with buried microchannel structures using thermally sacrificial polymers was reported. These previous methods required separate lithographic and etching sequences to pattern the sacrificial polymer.
