Trends in Structural and Spectroscopic Signatures of Iron(II) Complexes Supported by Systematically Varied Tetra‐N‐Heterocyclic Carbene Macrocycles

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The effects of ligand ring size and peripheral substitution on geometric and electronic structures as well as electrochemical and spectroscopic properties of a family of iron(II) complexes with macrocyclic tetracarbene ligands, often called organometallic heme analogues, have been analyzed, to provide structure/property correlations as a basis for ...

Fabrication of electrospun PVDF nanofibrous membrane for filtration of coconut inflorescence sap

open access: yesFood Biomacromolecules, EarlyView.
Electrospinning conditions for polyvinylidene difluoride (PVDF) nanofibrous membrane were optimized. The polymer solution's properties were analyzed. The developed membranes' average pore size was 478–543 nm. A fabricated membrane was used for the filtration of coconut inflorescence sap.
