This work describes the effect of the laser power and the exposure time on a sample of
octahedron‐shaped nanocrystals of cobalt (II) oxide using Raman spectroscopy. Above a …

Manganese oxides occur typically as cryptocrystalline and fine‐grained mixtures of different
Mn‐phases, carbonates, silicates, and Fe oxides/hydroxides; thus their characterization by …

An ever-increasing energy demand has stimulated intense research into electrochemical
technologies for both energy storage and conversion such as unitized regenerative fuel cells …

Abstract Titanium substituted BaFe 12− x Ti x O 19 (x≤ 1) barium hexaferrites have been
synthesized using the solid phase method. The phase purity and the crystal structure of the …

Raman spectroscopic studies of carbonaceous materials are, until now, mainly devoted to
geological and industrial materials. On the other hand, it is known from artistic literature that …

In this work, hierarchical manganese–nickel sulfide nanosheet arrays (Mn–Ni–S NAs) were
designed through a cost-effective hydrothermal method, followed by an ion-exchange …

Mixed Mn/Ru oxide thermally prepared electrodes using different compositions of Mn and
Ru precursor salts have been fabricated on Ti supports via thermal decomposition at two …

MnO microspheres with and without carbon coating are prepared as anode materials for
lithium ion batteries. The MnO microsphere material shows a reversible capacity of …

Aqueous zinc ion batteries (AZIBs) have become one of the most prospective energy
storage devices due to their low cost, abundant resources, and hypotoxicity. However, AZIBs …
