\section*{General remarks}

This template is designed to simplify the preparation of manuscripts across various LaTeX-based systems and streamline their evaluation by reviewers. To achieve this, we employ a minimal set of LaTeX packages. In case of technical conflicts, certain packages can be deactivated by commenting out the relevant lines. Upon acceptance, all drafts will be professionally formatted according to the style established for the Journal of Mesoscience and Nanotechnology by our technical team.


\smallskip
All references should be included in the tex-file. Using a separate bibliography file complicates formatting the reference list with hyperlinks both in papers and on web pages.

\smallskip
Although ORCIDs and DOIs do not appear in authors' list, main text, or reference list, these identifiers enable us to create hyperlinks to authors' personal webpages or journal websites where the cited papers were published.

\smallskip
If necessary, the authors may provide a PDF file containing supplementary information such as extensive figures, detailed experimental procedures, mathematical derivations, modeling programs, circuit diagrams, technical notes, measurement details, data acquisition methods, and filtering processes. This additional material will be valuable for both reviewers and specialized readers.

\smallskip
Our journal accepts various types of articles, including reviews, research articles, letters, methodological notes, and perspectives. Letters are typically limited to 4,000 words, whereas other manuscript types have no specific word limit.

\section*{Abstract}

Abstract should consist of one paragraph and be completely self-contained. The length of the abstract is typically limited by 200--250 words. The abstract should concisely summarize the subjects, conclusions, and results of the manuscript. If necessary, cite the relevant paper(s) in a full form, for example, First \emph{et al.}, Phys. Rev. Lett., vol. 111, 222 (2020).

\section*{Graphical abstract}

Authors should submit a single, high-quality image that effectively captures the core of their work for display on the Journal's website. Graphical abstracts should be submitted as a separate PDF-file. The typical dimensions for such images are 8.5 cm by 4.5 cm using a minimum resolution of 300 dpi.

\section*{Main text}

\,

Please write a concise and informative introduction addressing the problem, supported by relevant references. Clearly state the main findings of the manuscript and explain how they relate to previous publications and known effects.

\smallskip
Please minimize the use of acronyms. When using acronyms, ensure each one is properly defined within the text. For longer lists of acronyms, create a separate section to summarize all acronyms and their meanings.

\smallskip
Number all essential equations on the right.

\smallskip
Punctuate mathematical expressions and displayed equations as part of the sentence.

\smallskip
Use italic font for scalar variables ($x$, $y$, $I$, $V$).

\smallskip
Use roman boldface font for two- and three-dimensional vectors: ${\bf r} = x {\bf e}_x + y {\bf e}_y + z {\bf e}_z$, ${\bf B} = {\rm rot} {\bf A}$.

\smallskip
Use roman standard font for functions ($\sin x$, $\arctan y$) and for chemical elements (Pb, NbSe$_2$, YBa$_2$Cu$_3$O$_{7-\delta}$).

\smallskip
Typographically distinguish matrices, vectors and operators to avoid confusion.

\smallskip
Combine references in a single list at the end of the paper. Provide full bibliographic information, including all author names for references with up to ten authors, title, volume and issue, pages or article number, year of publication, and DOI. For more than ten, up to 20 names can be listed followed by \emph{et al.} as appropriate.

\smallskip
Number the references consecutively in the order in which they are cited. Provide sufficient information to enable the reader to locate cited items not available in the published literature (for example, report, books, conference proceedings).

\smallskip
Footnote comments\footnote{The example of the footnote comment.} are also acceptable.

\smallskip
Figures should preferably be in PDF format, or in EPS, JPG, or PNG formats, in either vector or raster types (better than 300 dpi).
Simple figures can be embedded in the text (see figure \ref{Fig1}). Figures consisting of several panels are recommended to be organized as two-column-wide figure  (see figure \ref{Fig2}). Please note that all labels, numbers, and legends in the figures should have the font sizes close to the font size of the main text (9--10 pt).

\smallskip
Simple mathematical formulas $a^2 + b^2 = c^2$ and $z=r e^{i\varphi}$ can be embedded in the text.

\smallskip
Example of a single-line formula (see Eq. (\ref{Eq1}))
\begin{equation}
\label{Eq1}
E = mc^2.
\end{equation}

\smallskip
Complicated mathematical expressions can be presented in the form of a two-line formula (see Eq. (\ref{Eq2}))
\begin{multline}
\label{Eq2}
i \hbar \frac{\partial}{\partial t} \Psi({\bf r}, t) = \hat{H} \Psi({\bf r}, t), \\ \hat{H} = \frac{1}{2m} \left(-i\hbar\nabla - \frac{q}{c} {\bf A}\right)^2 + U(\textbf{r}).
\end{multline}
Please note that the 'multline' environment requires the amsmath package

\smallskip
There are some examples of citations. Experimental methods \cite{Millikan-13, Davisson-27, Abbott-16} are crucial in physics because they allow scientists to test hypotheses and validate theories. Millikan demonstrated the discreteness of electrical charge \cite{Millikan-13}. Davisson and Germer [\citeonline{Davisson-27}] studied electron diffractions in crystals. Abbott \emph{et al. } [\citenum{Abbott-16}] reported on the detection of gravitational waves.
