Gradual reset and set characteristics in yttrium oxide based resistive random access memory

Semiconductor Science and Technology, 2019
This paper addresses the resistive switching behavior in yttrium oxide based resistive random access memory (RRAM) (TiN/yttrium oxide/Pt) devices. We report the coexistence of bipolar and unipolar resistive switching within a single device stack.

Improved Dry‐Pressing Strategy for Fabricating Double‐Sided Rough YSZ Electrolyte Thin Films and Their Performance in Solid Oxide Cells

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study addresses limitations of the conventional dry‐pressing method for electrolyte‐supported films—smooth surfaces, excessive thickness, and fragile supports inducing damage. We propose an innovative camphor–quartz sand composite architecture to construct a five‐layer (camphor/quartz sand/YSZ/quartz sand/camphor) system, enabling thin ...

From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp

Journal of Applied Polymer Science, EarlyView.
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating
