3d Printing Of Lunar Regolith Based Ceramics Via The Dlp Method, Ricardo Vasquez
2022 MME Undergraduate Research Symposium
Ceramic parts generally have poor machinability due to their high hardness and high brittleness. Researchers and industries have overcome the difficulty of machining ceramics and have manufactured parts with intricate geometry by using pre-ceramic polymers in stereolithography (SLA) 3D printing and using slurries based on ceramic powder and photopolymer resin in digital light processing (DLP) 3D printing, among other methods. This presentation will discuss the processes involved in the 3D printing of ceramic and ceramic composite parts via the DLP technique. A vital step in ceramic 3D printing is to optimize the printing parameters for a specific slurry formulation in โฆ

LithiumโSulfur (Li-S) batteries have attracted attention due to their high-energy density, 2500 Wh/๐๐๐๐๐๐ [1], and theoretical capacity of 1672 mAh/g-S [2]. In addition to that, sulfur abundance makes it a good candidate for rechargeable batteries. However, Li-S system has a few challenges that hinder its commercialization. Such as the insulating nature of the sulfur element, volume expansion, capacity fade due to intermittent polysulfide dissolution in the electrolyte and drop in capacity during the initial discharge cycles [3]. Herein, we have designed a Li-S in-operando optical observation cell, which allowed us to visualize the formation of higher to lower-order polysulfides as โฆ
