Abstract

Randomly oriented nanofibers of nickel cobaltite (NCO) were fabricated using sol–gel electrospinning followed by calcination. The precursor fibers were collected on rotating disc (RDI) and rotating drum (RDR) collectors. Variable fictitious forces produce continuous deflection at each fiber landing position on the RDI collector, which subjects the nanofibers to non-bundling. On the other hand, in the case of the RDR collector, the fictitious forces act just at the surface, and these forces merely cause slip of the fibers along the rotational axis of the RDR. This slip along with the retained Columbic charges on the surface of the fibers produces fiber bundling, which affects the morphological and structural properties of the NCO nanofibers obtained by calcining the precursor fibers. The use of the RDI collector in sol–gel electrospinning is a simple and optimal method of fabricating precursor nanofibers, which yields non-agglomerated and impurity-free inorganic nanofibers.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
