CuO‐CuAl2O4 Catalyst for Synthesis of 1‐Methylindole by Alcohol Amine Method

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Cu‐based catalysts used for the vapor‐phase synthesis of 1‐methylindole from N‐methylaniline and ethylene glycol are prone to Cu sintering and deactivation under the reaction conditions. In this work, CuO‐CuAl2O4 catalysts were prepared by a coprecipitation method and applied to the synthesis of 1‐methylindole via alcohol amine route.

Multifunctional PVC/PVA‐ZnO Nanocomposites: Bridging Dielectric Response and Antibacterial Activity for Active Packaging Applications

open access: yesJournal of Applied Polymer Science, EarlyView.
PVC and PVA polymer blends are studied as a function of frequency at room temperature to find the composition that gives the AC conductivity. The blend that has 75% PVC and 25% PVA is chosen as the matrix. Then 10% ZnO nanoparticles are added for food packaging. The change, in conductivity is used as a sign of activity and food freshness.

Electrospun PVDF/BaTiO3‐TiO2 Nanocomposite Yarns for Piezoelectric Energy Harvesting

open access: yesJournal of Applied Polymer Science, EarlyView.
Hybrid BTO‐TiO2 nanofillers integrated into electrospun PVDF fibers significantly enhance β‐phase formation and piezoelectric performance. The resulting nanocomposite fibers and twisted yarns generate high voltage and power output under mechanical stimulation.

Barrier Properties and Crystalline Structure of Biowax‐Containing Water‐Based Polymer Dispersions Under Different Processing Conditions

open access: yesJournal of Applied Polymer Science, EarlyView.
This study investigates the nanoscale structures of biowax materials using the wide‐angle x‐ray scattering method. The biowaxes are combined with water‐based polymer dispersions to create barrier coatings for fiber‐based food packaging materials.

Diol Chain‐Length Effects in Adipate and Succinate Polyesters for Thermoplastic Polyurethanes

open access: yesJournal of Applied Polymer Science, EarlyView.
This study examines 20 aliphatic polyesters as soft segments for thermoplastic polyurethanes (TPU), synthesized from adipic or succinic acid and diols (C2, C3, C4, C5, and C6). A pronounced odd‐even effect shows that even diols crystallize, while odd diols remain amorphous.
