Summary: This study comprehensively investigated the transverse magneto-optical Kerr effect (TMOKE) with gas sensing ability by directly patterning a subwavelength periodic nanogroove on a cobalt film. High-amplitude TMOKE was observed, which was 243 times as intense as that of a smooth film. The physical mechanism responsible for this improvement was elucidated by activating surface plasmon resonance at the gas-cobalt interface.

Summary: In this study, Au@Pt nanohybrids with surface plasmon resonance and spin-orbit coupling effects were fabricated using a microfluidic technique. The Au@Pt nanohybrids were directly dripped onto a CoFeB/W film as a deposition layer, and its dual-mode resonance was applied to increase the longitudinal saturated magneto-optical Kerr angle of the CoFeB/W film by 4.4 times. The innovative concept of using dual-mode resonance in this paper provides a new idea for the further search of materials with large magneto-optical coefficients.

Summary: Magnetoplasmonic nanostructures with magnetic and metallic compositions have attracted significant attention due to their ability to greatly enhance the transverse magneto-optical Kerr effect (T-MOKE) through surface plasmon resonance (SPR) excitations, leading to extremely high detection performance. In this study, a bilayer heterogeneous grating consisting of gold and cerium-substituted yttrium iron garnet layers on a gold film is proposed to achieve remarkable SPR enhancement of T-MOKE. Numerical simulations using the finite-element method demonstrate that the proposed structure significantly improves sensing performance in terms of incident angle and wavelength, with high detection sensitivity and a figure of merit that is an order of magnitude better than previously reported results. Moreover, the proposed structure can be utilized for fabrication of devices for sensing gaseous media.

Summary: The waveguide properties of a parabolic graded-index slab in a Kerr nonlinear medium are theoretically described. The model includes a dielectric function consisting of two parts with different optical properties. The optical properties of the nonlinear medium are characterized by a dielectric function depending on the electric field intensity, while the slab's properties depend on the distance with a parabolic profile. An explicit analytical solution to the wave equation with this dielectric function is found. The solution describes electric guided wave modes localized near and propagating along the slab.

Summary: The study reports that inhibiting the imaginary part of the electrical impedance exhibited by reduced graphene oxide (rGO) leads to stronger conductivity and an enhancement in optical nonlinearities, attributed to a highly uniform incorporation of plasmonic nanoparticles. The vectorial nature of the third-order nonlinear optical response exhibited by rGO decorated with platinum nanoparticles (Pt/rGO) was analyzed through a two-wave mixing experiment. The optical Kerr effect exhibited by Pt/rGO has potential for developing all-optical switching devices and immediate applications for encrypting and processing ultrafast functions.

Summary: This article analyzes how an electric field can induce a band gap shift in NiO films to enhance their third-order optical nonlinearities. It suggests that an electrochromic effect is responsible for changes in absorbance and modification in off-resonance nonlinear refractive index. The optical Kerr effect is identified as the main physical mechanism in a nanosecond two-wave mixing configuration at 532 nm wavelength. The absence of multi-photon absorption is confirmed by the constant trace of high-irradiance optical transmittance in single-beam mode. The study of nonlinear optical signals allows the proposal of an exclusive disjunctive logic gate assisted by an electrochromic effect in an optical Kerr gate. The influence of a switchable probe beam transmittance and electrical signals on asymmetric encryption by the XOR system is also studied. Immediate applications for developing multifunctional quantum systems driven by dynamic parameters in electrochromic and nonlinear optical materials are emphasized.

Summary: This report analyzes the asymmetry effects of an electric field on nonlinear optical signals in NiO thin solid films. The samples were prepared using a spray pyrolysis method and had a thickness of approximately 110 nm. The change in nonlinear refractive index was evaluated by nanosecond pulses at 532 nm using the z-scan technique. Nonlinear optical absorption was confirmed to be absent before ablation occurs in the nonlinear media. Numerical simulations were conducted to analyze non-reciprocal energy transfer and the optical Kerr effect under an applied voltage. Potential applications include controlling nonlinear waveguiding structures and optical systems with multidirectional functions.

Summary: This study analyzes the optical effects of blood plasma under healthy/unhealthy conditions and the evolution of nanovehicles composed of nanodiamonds (NDs) encapsulating liposomes (L) in these biofluids. Optical ablation of liposome clusters was achieved and controlled using a standard two-wave mixing laser light method. The release of NDs was facilitated by thermal damage during the sedimentation process of the nanovehicles interacting with the laser beams barrier. The findings of this research include the threshold temperature for the release of NDs from liposomes and the assessment of the release based on the numerical magnitude of Quantum Yield.

The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.
