“…A higher percentage of Fe 3+ in O h sites will lead to increased magnetization. 80,81 At 5 K and 300 K, CdFe-190-C exhibits a higher magnetization than the other samples due to the higher percentage of Fe 3+ ions in O h sites in this sample (see Table 3). CdFe-130-C and CdFe-160-C have a similar fraction of Fe 3+ ions in O h sites, while the fraction of Fe 3+ ions in T d sites is more in CdFe-130-C compared to that in CdFe-160-C.…”

“…Among spinel ferrites, multicomponent zinc ferrites assume particular significance. Pure zinc ferrite is classified as a normal spinel, characterized by the presence of 8 divalent Zn 2+ cations at tetrahedral positions and 16 trivalent Fe 3+ cations at octahedral positions [5]. Conversely, magnesium ferrite belongs to the inverted spinel category, with 8 divalent Mg 2+ cations occupying 8 of the 16 available octahedral positions, and 16 trivalent Fe 3+ cations distributed between 8 tetrahedral and 8 octahedral positions [6].…”

Zinc-manganese ferrite nanoparticles, denoted as Zn x Mg 1−x Fe 2 O 4 where x ranges from 0 to 1, were synthesized via solution combustion employing glycine as the organic fuel at a stoichiometric redox ratio. The resultant compositions underwent comprehensive characterization utilizing scanning electron microscopy, energy-dispersive spectroscopy, and powder X-ray diffractometry. Magnetic and electrochemical properties were meticulously examined using a vibrating magnetometer and cyclic voltmeter, respectively. Analysis revealed an average particle size ranging from 24.9 to 30.8 nm across all synthesized samples, with degrees of crystallinity reaching 93-96%. Notably, variations in the magnetic behavior were observed depending on the magnesium content within the samples. The highest magnetic parameters were recorded for Zn 0.4 Mg 0.6 Fe 2 O 4 (M s = 27.78 emu/g, M r = 3.77 emu/g, and H c = 21.4 Oe). Furthermore, the electrochemical capacity of the synthesized powders exhibited dependency on the incorporation of magnesium cations into the crystal lattice. These findings underscore the significance of magnesium content in modulating the magnetic and electrochemical properties of Zn x Mg 1−x Fe 2 O 4 nanoparticles synthesized via solution combustion. KEYWORDS zinc-manganese ferrite, nanoparticles, magnetic properties, electrochemical properties. ACKNOWLEDGEMENTS The reported study was funded by Russian Science Foundation (grant no. 21-73-10070).

Pancreatic cancer is characterized by a high mortality rate and unfavorable prognosis. This is primarily attributed to poor accumulation of therapeutic agents at the target site due to the presence of a highly complex tumor microenvironment surrounding the pancreatic cancer tissue. However, a promising avenue for targeted drug delivery has emerged in the form of stimuli‐responsive materials. These advanced nanocarriers, encompassing both external and internal stimuli‐responsive nanoparticles, can be formulated to control the release of therapeutic agents precisely in response to specific activation. By harnessing external stimuli such as light, ultrasound, or magnetic fields, as well as intrinsic biological triggers including pH, redox potential, hypoxia, and temperature, these nanomaterials exhibit ‘intelligent’ and selective responses within complex biological environments. These responsive nanoparticles have been shown to address challenges associated with poor vascularity and thick desmoplastic stromal layers, which are hallmarks of pancreatic cancer, by promoting enhanced drug accumulation and release at the target site relative to conventional therapy. This work explores the design strategies for advanced stimuli‐responsive nanomaterials, integrating both internal and external stimuli, with the potential to enhance drug delivery efficacy in pancreatic cancer. It addresses the challenges and prospects in their development and offers insights for future clinical applications.
