The integration of the Metaverse into innovative education has the potential to transform traditional teaching methods, offering new opportunities for both in-person and remote learning, ultimately making education more engaging and effective. This research aims to provide a cutting-edge assessment of how the Metaverse is integrated into education specific to science learning in the context of future employment. This article highlights its contemporary relevance and novel insights. This qualitative descriptive study uses data-gathering procedures based on the library research method. Metaverse platforms offer immersive and interactive experiences that enhance students’ understanding of scientific concepts. Metaverse-based science learning is not confined by geographic limitations, enabling a broader audience to access quality educational content. Researchers are increasingly interested in investigating the effectiveness of metaverse-based science learning, and industry support and investment drive innovation in this field. However, this study is limited in its reliance on Scopus as the sole source of articles. Nevertheless, this research is a valuable resource for educators seeking to integrate the Metaverse into science education. Researchers recommend that future researchers conduct more targeted literature reviews focusing on specific learning models, subjects, educational levels, and curriculum variations.

“…The concept of WD was first introduced by E. Wigner in 1932 in the context of quantum mechanics [1]; approximately fifteen years later, it was employed by J. Ville [2] in the study of non-stationary signals, and then explored by L. Cohen [3][4][5][6], B. Boashash [7][8][9], L. Stanković [10][11][12], G. Folland [13], and P. Korn [14] from the perspective of time-frequency analysis. As one of the most important time-frequency analysis techniques, the WD has found many applications in communication, seismic signal analysis, radar, sonar, image processing, and optical signals processing [15][16][17][18][19][20]. For a function f ∈ L 2 (R N ), its WD is defined by…”

In order to achieve time–frequency superresolution in comparison to the conventional Wigner distribution (WD), this study generalizes the well-known τ-Wigner distribution (τ-WD) with only one parameter τ to the multiple-parameter matrix-Wigner distribution (M-WD) with the parameter matrix M. According to operator theory, we construct Heisenberg’s inequalities on the uncertainty product in M-WD domains and formulate two kinds of attainable lower bounds dependent on M. We solve the problem of lower bound minimization and obtain the optimality condition of M, under which the M-WD achieves superior time–frequency resolution. It turns out that the M-WD breaks through the limitation of the τ-WD and gives birth to some novel distributions other than the WD that could generate the highest time–frequency resolution. As an example, the two-dimensional linear frequency-modulated signal is carried out to demonstrate the time–frequency concentration superiority of the M-WD over the short-time Fourier transform and wavelet transform.

“…In the meantime, potentiometric methods using ion-selective electrodes have emerged as a replacement as they offer significant advantages over these techniques, such as portability, low cost and real-time analysis. [20][21][22] The potentiometric method, an environmentally friendly analytical technique, has the advantage over the costly and complex analytical methods that it is fast, inexpensive, portable and economical. However, changing the electrode surface can affect the low sensitivity or selectivity and the undesirable detection limits.…”

The unique properties of calcium oxide (CaO) and zinc oxide (ZnO) at the nanoscale have attracted the interest of scientists as promising electrically conductive substances for sensing purposes. The content of terbinafine hydrochloride (TRF) in pharmaceutical tablets was determined using a novel coated, wire‐functionalized CaO/ZnO nanocomposite membrane sensor biogenically produced from Lavandula spica extract. Sodium tetraphenylborate was used to prepare the active material (TRF‐TBP). The newly modified sensor gave excellent potentiometric sensitivity with the least squares regression equation EmV=(−58.88X±0.3)+log [TRF]+549.78 and covered a wide linear range (5.0×10−9–1.0×10−2 mol/L) of TRF samples. In contrast, the standard TRF‐TBP sensor wasn't as sensitive when (2.5×10−6–1.0×10−2 mol/L). TRF solutions with regression equation of (−55.728X±0.7)+log [TRF]+396.64. The appropriate pH range was 3–6. The principles of analytical methodology were applied to investigate the validity and suitability of the proposed technique. The proposed sensors were found to be suitable and efficient for the detection of TRF on tablets.
