A new method for assessing the utility of powder bed fusion (PBF) feedstock
Mani Gonzalez, Pierre Giovanni; E. Gorji, Nima; Saxena, Prateek; Corfield, Martin; Clare, Adam; Rueff, Jean-Pascal; Bogan, Justin; Snelgrove, Matthew; Hughes, Greg; O'Connor, Robert; Raghavendra, Ramesh; Brabazon, Dermot (2020-01-29)Recycling metallic powders used in the additive manufacturing (AM) process is essential for reducing the process cost, manufacturing time, energy consumption, and metallic waste. In this paper, the focus is on pore formation ... -
Analysis of Al and Cu salt infiltration into a poly 2-vinylpyridine (P2vP) polymer layer for area selective deposition applications
Mani Gonzalez, Pierre Giovanni (2020-01)This work is motivated by the desire to develop a semiconductor device patterning technology based on precursor infiltration into block copolymer materials. Developing an understanding of the preferential infiltration of ... -
Hard x-ray photoelectron spectroscopy study of copper formation by metal salt inclusion in a polymer film
Snelgrove, Matthew (2019-08-08)In this work we present the results of a hard x-ray photoelectron spectroscopy (HAXPES) study on the creation of metallic copper layers via metal-salt infiltration into a poly-2-vinylpyridine (P2VP) film. Metal salt inclusion ... -
Precise Definition of a “Monolayer Point” in Polymer Brush Films for Fabricating Highly Coherent TiO2 Thin Films by Vapor-Phase Infiltration
Mani Gonzalez, Pierre Giovanni; Lundy, Ross; Yadav, Pravind; Prochukhan, Nadezda; C Giraud, Elsa; F O’Mahony, Tom; Selkirk, Andrew; Mullen, Eleanor; Conway, Jim; Turner, Miles; Daniels, Stephen; Snelgrove, Matthew; Bogan, Justin; McFeely, Caitlin; O’Connor, Robert; McGlynn, Enda; Hughes, Greg; Cummins, Cian; A Morris, Michael (2020-10-06)In this work, we show that in order to fabricate coherent titania (TiO2) films with precise thickness control, it is critical to generate a complete polymer brush monolayer. To date, demonstrations of such dense polymer ... -
Surface characterization of poly-2-vinylpyridine—A polymer for area selective deposition techniques
Snelgrove, Matthew (2019-09-02)Thin films of OH terminated poly-2-vinylpyridine (P2VP), a polymer with potential for infiltration mediated thin film deposition, area selective deposition (ASD), and small feature size development via block copolymer (BCP) ...
