Sacrificial Polymers for Rapid Manufacturing of Vascular Materials
2019Conventional vascularization methods for making multifunctional composites are limited by time and energy-intensive processes. Exothermic curing of the host matrix with simultaneous degradation of the sacrificial polymer enables rapid manufacturing of vascular polymers and composites.

Development of Freeze-Form Extrusion Fabrication With Use of Sacrificial Material
Journal of Manufacturing Science and Engineering, 2014The 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 ...

Thin-film magnesium as a sacrificial and biodegradable material
2014 IEEE 27th International Conference on Micro Electro Mechanical Systems (MEMS), 2014This 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.

Photoinitiation systems and thermal decomposition of photodefinable sacrificial materials
Journal of Applied Polymer Science, 2003AbstractThe exposure characteristics of norbornene‐based photosensitive sacrificial materials as functions of the photoinitiator have been investigated. The results show that the initiator, bis(2,4,6‐trimethylbenzoyl)‐phenylphosphine oxide, provides high photosensitivity and an adjustable contrast factor.

Releasing SU-8 structures using polystyrene as a sacrificial material
Sensors and Actuators A: Physical, 2004Abstract We have successfully developed a new method to release SU-8 structures with polystyrene as a sacrificial material. Toluene is initially used to dissolve solid polystyrene, and the resulting solution is employed to spin coat a sacrificial polystyrene layer onto a glass plate prior to SU-8 deposition.

Biofabrication of valentine-shaped heart with a composite hydrogel and sacrificial material
Materials Science and Engineering: C, 20203D 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

Na2S sacrificial cathodic material for high performance sodium-ion capacitors
Electrochimica Acta, 2019Abstract Sodium sulfide (Na2S) has been used as sacrificial material for the presodiation of a Sn4P3 negative electrode in order to realize a high-performance sodium-ion capacitor (NIC). In two-electrode cells with Na counter/reference electrode and 1 mol L−1 NaClO4 electrolyte, sodium could be irreversibly extracted from Na2S at potential lower than

Crystallographic defect studies in SIMOX material thinned by sacrificial oxidation
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1994Abstract Crystallographic defects present in thermal oxidised SIMOX materials have been studied by means of plan view transmission electron microscopy (TEM) and chemical defect etching. It is observed that the presence of small stacking fault tetrahedra near the top Si/SiO2 interface influence the formation of oxidation induced stacking faults (OISF).

Biomaterials, 2017
A major challenge in tissue engineering is the lack of proper vascularization. Although various approaches have been used to build vascular network in a tissue engineering construct, there remain some drawbacks. Herein, a glucose-sensitive self-healing hydrogel are employed as sacrificial materials to fabricate branched tubular channels within a ...

Advanced Mg-Mn-Ca sacrificial anode materials for cathodic protection
Materials and Corrosion, 2001Addition of calcium to the Mg-Mn sacrificial anodes enhanced the anode efficiency by promoting the uniformly distributed corrosion along the grain boundaries and increased the driving potential by intrinsic electronegative potential of α-Mg. The reason for the uniform intergranular corrosion is that Mg 2 Ca precipitate (cathode) at grain boundaries is ...
