Insight into copper and iron ion sequestration from liquid-phase environment by microcrystalline cellulose biosorbent: experimental and modelling analyses
Published 2024“…The maximum sorption capacity of MCC was 534.61 mg/g and 845.75 mg/g, respectively, for Cu(II) and Fe(II) ions at room temperature. Pseudo-second-order model best describes the copper and iron kinetic data, signifying the dominance of chemisorption adsorption relation between the negatively charged MCC and adsorbates. …”

Electronic structure of paramagnetic transition metal complexes
Published 2017“…In Chapter 3, we address the question of redox-dependent spin transitions in triangular iron complexes. Experiments have shown that one-electron reduction of a pyrazolate-bridged Fe<sup>III</sup><sub>3</sub> cluster drives a transition from high- to low-spin configurations at all three metal centres. …”

Quantum tunneling of magnetization in ultrasmall half-metallic V3O4 quantum dots : displaying quantum superparamagnetic state
Published 2013“…The quantum superparamagnetic state (QSP) as a high temperature signature of QTMs is observed at 16 K, which is beyond absolute zero temperature and much higher than that of conventional iron-based compounds due to the stronger spin-orbital coupling of V3+ ions bringing high anisotropy energy. …”
