Ultrasound–Calcination Synergistic Control of (Ce, La)PO4 Catalyst Structure for Enhanced Low‐Temperature NH3‐SCR Performance

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, (Ce, La)PO4 catalysts were synthesized via an ultrasound‐assisted method. The effects of ultrasound duration and calcination temperature on the low‐temperature NH3‐SCR performance were systematically investigated. The results indicated that the (Ce, La)PO4 catalyst prepared with an ultrasound treatment time of 20 min and a ...

Incorporation of MoO3 Nanoparticles Into Polypropylene Fibers via Melt Spinning: Investigation of Mechanical, Thermal, and Chromic Properties

open access: yesJournal of Applied Polymer Science, EarlyView.
Pure PP and PP/MoO3 filaments produced by melt spinning. ABSTRACT Polypropylene (PP) composite fibers containing 0.10, 0.20, and 0.50 wt% molybdenum oxide (MoO3) nanoparticles were produced via melt spinning. In the present study, the effect of this addition on the mechanical, thermal, and chromic properties of the fibers was investigated.

Thermal Stabilization of Chitosan Yarn for Carbon Fiber Production

open access: yesJournal of Applied Polymer Science, EarlyView.
This study explores chitosan, a biopolymer derived from chitin, as a renewable precursor for carbon fiber production. The authors demonstrate that chitosan fibers can be successfully stabilized under controlled thermal conditions in air and nitrogen.
