Search of new core materials for magnetic fluid hyperthermia: Preliminary chemical and physical issues
Magnetic heating by cobalt ferrite nanoparticles
In the quest for suitable materials for hyperthermia we explored the preparation and properties of nanoparticles of Co ferrite. The material was produced by coprecipitation from water solution of Co…
Structural anomalies associated with the electronic and spin transitions in LnCoO3
Abstract.A powder X-ray diffraction study, combined with magnetic susceptibility and electric transport measurements, was performed on a series of LnCoO3 perovskites (Ln = Y, Dy, Gd, Sm, Nd, Pr and…
Beta-glucan complexes with selected nutraceuticals: Synthesis, characterization, and stability
The mathematical incorrectness of the integral isoconversional methods in case of variable activation energy and the consequences

- Computer ScienceJournal of Thermal Analysis and Calorimetry
It is shown that the integral isoconversional methods are mathematically incorrect if the activation energy depends on conversion, and non-sensical snake-like shape of the conversion versus time curves is observed when the kinetic results are extrapolated to lower temperatures.

Morphological studies revealed well-separated particles that form a stable water suspension and magnetic studies include magnetization measurements and investigation of the ferromagnetic–superparamagnetic–paramagnetic transition.
Synthesis and magnetic properties of Co1−xZnxFe2O4+γ nanoparticles as materials for magnetic fluid hyperthermia
HPLC Analysis of HI‐6 Dichloride and Dimethanesulfonate—Antidotes against Nerve Agents and Organophosphorus Pesticides
Abstract Description of the simple HPLC method with UV detection for the identification of the acetylcholinesterase reactivator–HI‐6 is described. Two salts of HI‐6 (dichloride and…
Novel quercetin derivatives in treatment of peroxynitrite-oxidized SERCA1
The protective effects of Q and MPQ on different isoforms of SERCA activity may be useful in prevention and treatment of inflammation or muscle diseases, and the inhibitory effect of CHQ on SERCA isoforms may be beneficial in therapeutic approaches aimed at anti-tumor treatment.
