“…For instance, Liu et al. (2023) fabricated Fe 3 O 4 @SiO 2 @Au MP nanocomposites and, using 4‐mercaptopyridine (4‐MPy), conducted indirect detection of Hg 2+ metal ions in water [97] . The primary objective was to protect the magnetic core from oxidation and provide ample surface area for the plasmonic component of the nanocomposite, facilitated by the SiO 2 shell.…”

Surface‐enhanced Raman scattering (SERS) spectroscopy, a highly sensitive technique for detecting trace‐level analytes, relies on plasmonic substrates. The choice of substrate, its morphology, and the excitation wavelength are crucial in SERS applications. To address advanced SERS requirements, the design and use of efficient nanocomposite substrates have become increasingly important. Notably, magnetic‐plasmonic (MP) nanocomposites, which combine magnetic and plasmonic properties within a single particle system, stand out as promising nanoarchitectures with versatile applications in nanomedicine and SERS spectroscopy. In this review, we present an overview of MP nanocomposite fabrication methods, explore surface functionalization strategies, and evaluate their use in SERS. Our focus is on how different nanocomposite designs, magnetic and plasmonic properties, and surface modifications can significantly influence their SERS‐related characteristics, thereby affecting their performance in specific applications such as separation, environmental monitoring, and biological applications. Reviewing recent studies highlights the multifaceted nature of these materials, which have great potential to transform SERS applications across a range of fields, from medical diagnostics to environmental monitoring. Finally, we discuss the prospects of MP nanocomposites, anticipating favorable developments that will make substantial contributions to various scientific and technological areas.

“…Specifically, we can investigate properties of repulsive gravity in the context of relativistic astrophysics, see e.g. [56], in connection with geodesic motions and equilibrium. Hence, under this requirement, one can search for new regular solutions that satisfy this condition.…”

We evaluate the effects of repulsive gravity using first order geometric invariants, \textit{i.e.}, the Ricci scalar and the eigenvalues of the Riemann curvature tensor, for three regular black holes, namely the Bardeen, Hayward, and Dymnikova spacetimes. To examine the repulsive effects, we calculate their respective onsets and regions of repulsive gravity. Afterwards, we compare the repulsive regions obtained from these metrics among themselves and then with the predictions got from the Reissner-Nordstr"{o}m and Schwarzschild-de Sitter. We find that the Dymnikova spacetime does not exhibit regions in which gravity changes its sign. A notable characteristic, observed in all these metrics, is that the repulsive regions appear to be unaffected by the mass that generates the regular black hole. This property emerges due to the invariants employed in our analysis, which do not change sign through \emph{linear combinations} of the mass and the free coefficients of the metrics. As a result, gravity can change sign independently of the specific values acquired by the mass. This conclusion suggests a potential \emph{incompleteness} of regular solutions, particularly in terms of their repulsive effects. To further highlight this finding, we numerically compute, for the Reissner-Nordstr"{o}m and Schwarzschild-de Sitter solutions, the values of mass, $M$, that emulate the repulsive effects found in the Bardeen and Hayward spacetimes. These selected values of $M$ provide evidence that regular black holes do not incorporate repulsive effects by means of the masses used to generate the solutions themselves. Implications and physical consequences of these results are then discussed in detail.

“…Al 2 O 3 is considered one of the most commonly used support materials for loading noble metals due to its unique surface configuration and excellent chemical stability. [18][19][20] Unlike reducible oxides and semiconducting oxides, Al 2 O 3 acts as an inert support with non-reducing and insulating properties, which leads to the electronic interaction between metal NPs and Al 2 O 3 not being a concern. 21 In previous studies, the coordinatively unsaturated Al 3+ centers and terminal hydroxyls on the surface of γ-Al 2 O 3 have been identified as anchoring sites for metallic atoms to achieve high dispersion and thermal stability of the supported metal phase.…”
