The CP nanoparticles have been thoroughly characterized using spectroscopic and microscopic techniques to determine their size, shape, elemental composition, and the oxidation states of the constituent elements.

This reduction in leachates was observed across all four tested resins, indicating the general applicability of this method. Materials marketed as biocompatible did not affect stem cell growth and only had a minor effect on differentiation after a 60-minute wet autoclave treatment, unlike non-wet autoclaved parts, which showed marked effects. We assessed cellular function using morphology, viability assays, functional assays, and metabolomics. While no immediate effects were observed from the tested materials after wet autoclavation, transcriptomic analysis revealed that sub-cytotoxic levels of leachates downregulated extracellular matrix genes and upregulated genes related to cell adhesion and lipid and fatty acid metabolism. These changes could have long-term implications.

Structural stability is rigorously validated through geometric optimization, mechanical stability criteria, and tolerance factor analysis, confirming the feasibility of these compounds in the cubic &lt;em&gt;Fm&lt;/em&gt;&lt;img&gt;&lt;em&gt;m&lt;/em&gt; phase. Total energy calculations based on the Birch–Murnaghan equation of state establish a robust ferromagnetic ground state, further corroborated by positive Curie–Weiss constants of 98 K (Rb&lt;small&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;/small&gt;GeVI&lt;small&gt;&lt;sub&gt;6&lt;/sub&gt;&lt;/small&gt;), 90 K (Rb&lt;small&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;/small&gt;GeMnI&lt;small&gt;&lt;sub&gt;6&lt;/sub&gt;&lt;/small&gt;), and 95 K (Rb&lt;small&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;/small&gt;GeNiI&lt;small&gt;&lt;sub&gt;6&lt;/sub&gt;&lt;/small&gt;), underscoring their intrinsic ferromagnetic behavior. Electronic structure analyses performed using both the generalized gradient approximation (GGA) and the Tran–Blaha modified Becke–Johnson (TB-mBJ) potential reveal that these materials exhibit semiconducting ferromagnetism, characterized by a significant spin-splitting gap. The underlying mechanism is traced to the crystal field effects influencing the d-orbitals of the transition metal atoms.
