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 ...

Engineered assistive materials for 3D bioprinting: support baths and sacrificial inks

Biofabrication, 2022
Abstract Three-dimensional (3D) bioprinting is a promising technique for spatially patterning cells and materials into constructs that mimic native tissues and organs. However, a trade-off exists between printability and biological function, where weak materials are typically more suited for 3D cell culture but exhibit poor shape ...

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 ...

Characterization of Sacrificial Anode Materials through Laboratory Testing

CORROSION 1996, 1996
Abstract The electrochemical behaviour of sacrificial anode materials is of vital importance for the reliability and efficiency of cathodic protection systems for seawater exposed structures. As many sacrificial anode materials are proprietary alloys, many users require that anode manufacturers document the service performance and the ...

Microsystems manufacturing via embossing of photodefinable thermally sacrificial materials

SPIE Proceedings, 2004
Substantial recent interest in microelectronics manufacturing has motivated significant work on non-traditional processes such as embossing-based lithography. This work has been generally limited to manufacturing conventional microelectronics, producing two dimensional patterned surfaces and structures.

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.

DNA-templated nanowires as sacrificial materials for creating nanocapillaries

SPIE Proceedings, 2008
DNA has shown great promise as a template for the controlled localization of various materials and the construction of wires with nanometer-dimension cross sections. We have recently developed a strategy for fabrication of nanocapillaries, using DNA-templated nanowires as a sacrificial material.

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 ...

Aerosols over melts of a corium–sacrificial materials system

Glass Physics and Chemistry, 2016
The behavior of a melt of a UO2–ZrO2–SiO2–Fe3O4–CaO–Al2O3 system that is formed in the case of the dilution of corium (a melt of a UO2–ZrO2–Zr system) with sacrificial materials (a mixture of aluminum and iron oxides with Portland cement) has been studied. It has been found that, as a result of the evaporation of oxides, spherical aerosol particles are
