Summary: The thermodynamics of particle dispersion of maghemite nanoparticles in an ionic liquid were studied using potentiometric and calorimetric titrations. The solvent structure of the ionic liquid was found to be reinforced by the formation of neutral species. Different types of solvation in the acidic and basic domains were sufficient to ensure colloidal stability.

Summary: The study investigated the use of a cheap, high-efficiency, and eco-friendly adsorbent as an alternative to activated carbon coated Maghemite nanoparticles for removing lead and cadmium ions from aqueous solutions. The adsorbent showed good fit with Langmuir, Temkin and Freundlich isotherm models, and the maximum adsorption capacity for Pb (II) and Cd (II) ions was determined. The study also examined the kinetics and thermodynamics of adsorption, and demonstrated that Maghemite nanoparticle coated activated carbon derived from agricultural biomass is a promising option for removing metals from industrial effluents due to its cost-effectiveness, high efficiency, and environmental friendliness.

Summary: This study analyzed the association between the average 'adjusted' Global APS Score (aGAPSS) and the change in Damage Index for APS (DIAPS) in patients with thrombotic and non-thrombotic APS. The results showed that a higher average aGAPSS value was associated with an increase in DIAPS during follow-up, suggesting that the average aGAPSS score can predict the increase in DIAPS.

Summary: Antibody adsorption to NanoAct (R) nanoparticles is thermodynamically influenced, with greater adsorption and color intensity observed as pH decreases. Changes in net charge of the antibody surface as a function of pH impact the pH dependence of adsorption process. Increased positive charge on the antibody surface leads to a more sensitive NanoAct (R)-based immunoassay.

Summary: This article presents an analysis of the effect of HV-APS parameters on WC-CrC-Ni powder. The plasma spraying process utilized a three-electrode Axial III type torch with central powder injection, and a supersonic nozzle with a diameter of 5/16 inch. Variable parameters included power current per electrode, hydrogen flow rate, and powder feed rate. The obtained coatings exhibited low porosity and their hardness depended on the spraying parameters. The analysis suggests that the HV-APS process can produce carbide coatings with properties comparable to those obtained by the HVOF method and better than conventional plasma spraying (APS).

Summary: The electronic structure and ferroelectric-ferromagnetic coupling properties of Y-doped and vacancy-containing GaN-ZnO heterojunctions are systematically investigated. The magnetism in vacancy-containing systems is generated by the spin polarization of unpaired electrons induced by cationic vacancies, while in Y-doped systems, bound magnetic polarons are formed by the orbital hybridization of s-state and d-state electrons of Y-doped elements.

Summary: The elementary excitations spectrum of anisotropic frustrated antiferromagnets in the fan phase is discussed. It is found that the low-energy part of the spectrum consists of a gapless phason branch with linear dispersion and a gapped optical branch corresponding to the fan structure amplitude oscillations. In the high-energy part of the spectrum, the excitations are similar to the magnons of the fully polarized phase.

Summary: In this study, the departure frequency of vapor bubbles during boiling of ferrofluid in a horizontal magnetic field is experimentally investigated. Two methods, visual and inductive, are used to measure the frequency of bubble departure. The results show that the bubble departure frequency can decrease with increasing magnetic field strength and increase with increasing temperature of the heat-emitting surface. A linear stability analysis is conducted to analyze the influence of the magnetic field on the frequency of bubble formation during ferrofluid boiling.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
