Guide for Authors
MANUSCRIPT PREPARATIONGeneral Instruction
 Authors should prepare their manuscripts and “Cover Page” using the Authors’Template available on the journal website (http://www.sptj.jp/).
 Main text should be prepared as a MS Word® file.
 Figures should be prepared as TIF or JPG files with highest resolution possible.
 Tables should be prepared as a MS office application files (Excel ®, Word®,
PowerPoint®).
 Please also create a PDF file compiled from prepared files (Main text, Figures,Tables).
 Concise and informative.
 Technical terms should conform to ‘Terminology Dictionary of PowderTechnology’.
 Papers that have been accepted for publication are subject to the following page
limits: Regular articles: 5 printed pages; Notes: 3 printed pages.
 Headings and subheadings for different sections of the paper (e.g. Introduction,Methods, Results, Discussion, and Conclusion) should be clearly indicated.
 Units of measurement, abbreviations and symbols should follow the International
System of Units (Sl).
 Equations should be numbered consecutively with Arabic numerals in parentheseson the right-hand side of the page.
Article StructureIntroduction
 State the objectives of the work and provide an adequate background, avoiding adetailed literature survey or a summary of the results.
Material and methods
 Provide sufficient detail to allow the work to be reproduced. Methods alreadypublished should be indicated by a reference: only relevant modifications shouldbe described.
Results
 Results should be clear and concise.
Discussion
 This should explore the significance of the results of the work, not repeat them. A
combined Results and Discussion section is often appropriate. Avoid extensive
citations and discussion of published literature.
Conclusions
 The main conclusions of the study may be presented in a short Conclusions
section, which may stand alone or form a subsection of a Discussion or Resultsand Discussion section.
Appendices Appendices should be the last of the manuscript.
 Please avoid unnecessary use of appendices.
 If there is more than one appendix, they should be identified as A, B, etc. Formulaeand equations in appendices should be given separate numbering: Eq. (A.1), Eq.

(A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on. Similarly for tables andfigures: Table A.1; Fig. A.1, etc.
Cover page information
Title
 Title should be concise, informative, and reflect the content of the manuscript
briefly with informative words.
 Avoid abbreviations, chemical formula, subtitle, and product names wherepossible.
 Authors should not use "Part I," "Part II," or other similar phrases in the title.
 Authors should capitalize the initial letters of the main words.
 Do not capitalize coordinating conjunctions (e.g., and, but, or, nor, yet, so), articles(e.g., a, an, the), or prepositions, unless they appear as first word in the title.
Author names and affiliations
 Where the family name may be ambiguous (e.g., a double name), please indicate
this clearly. Present the authors' affiliation addresses (where the actual work wasdone) below the names.
 Indicate all affiliations with a lower-case superscript letter immediately after theauthor's name and in front of the appropriate address.
 Provide the full postal address of each affiliation, including the country name.
Corresponding author
 Clearly indicate who will handle correspondence at all stages of refereeing andpublication, also post-publication. Ensure that telephone and fax numbers areprovided in addition to the e-mail address and the complete postal address.
 The corresponding author use the e-mail address they were given by theirprofessional affiliation (university/institution/company).
 We are unable to formally publish any manuscripts without the corresponding
author's affiliation's email address in our journal, even though they are accepted.
Abstract

A concise and factual abstract of no more than 150 words for papers (100 wordsfor research notes) is required and should follow the title page on a separate sheet.
The abstract should state briefly the purpose of the research, the principal results
and major conclusions.
References should be avoided, but if essential, then cite the author(s) and year(s).
Also, non-standard or uncommon abbreviations should be avoided, but if essential
they must be defined at their first mention in the abstract itself.

Keywords
 Immediately after the abstract, provide a maximum of 5 keywords, using British
spelling and avoiding general and plural terms and multiple concepts (avoid, forexample, 'and', 'of').
 Be sparing with abbreviations: only abbreviations firmly established in the field
may be eligible.
 One keyword is limited to three words.
 Capitalize the initial letters of the first word for each keyword.
 Chemical elements and/or compounds should be indicated with full spelling, notthe chemical symbol.
 Do not use numerical characters as the first word for each keyword.



Avoid articles (e.g., a, an, the), coordinating conjunctions (e.g., and, but, or, nor,yet, so), or prepositions.

Acknowledgements Collate acknowledgements in a separate section at the end of the article before thereferences and do not, therefore, include them on the title page, as a footnote tothe title or otherwise.
Math formulae Please submit math equations as editable text and not as images.
 Write fraction, differential and integral formulae between two lines. However,when an equation is very short, you can write on one line with slash as: a/b.
 Use italic type for variables related to quantity, e.g., m (mass), ρ (density), p(pressure), τ (shear stress) .
 Use italic type for dimensionless parameters and constants, e.g., Re, Pe, Fr, Kn, k(Boltzmann constant), R (gas constant).
 Use roman type for units, e.g., Pa, N/(m2･s), kg/m3, rad･s-1.
 Enclose unit that follows symbol within square brackets. Do not use square
brackets for the symbol that follows value, e.g., τ [N･m-2], 1.013×102 kPa.
 Use roman type for chemical formulae, e.g., CO2, C2H4, SiCl4.
 Use roman type for mathematical symbols that describe constant and operator. Useitalic type for variable symbols. For example, roman type: exp, lim, “d” in du/dt
and italic type: u, t.
 Use roman type for subscripts and superscripts. However, italic type can be usedin the case of variable symbols, e.g., dp, xi.
 Use both italic and boldface types for vectors, e.g., υ, σ, A.
 When an equation is too long to fit on one line, break it before mathematicalsymbols (×, +, –).
 You must write a equation in sentences on one line. When the slash is used todescribe fraction and the dominator consists of more than two variables, enclosing
them using parentheses, ( ).
Footnotes

Footnotes should be used sparingly.
Use superscripts e.g., *1), *2) in the text to distinguish. Insert a line at the bottom of
the page and write the information blow the line.

Figures captions
 Put a list of figure caption at the end of the manuscript.
 Write caption number in text as Figs. 1, 2, Fig. 3. Use boldface type when it is firstappeared.
 Please refer the examples.
 Manuscript for print is produced by scaling down the manuscript written byauthors. Note the line thickness and font size, taking account of size of manuscript
printed.
 Put one figure on each page of A4 sized- paper. Prepare them around twice as large
as those printed.
 Use Times New Roman font for characters and numerals in figures.

TablesPut a list of table caption at the end of the manuscript.
Write caption number in text as Tables 1, 2, Table 3. Use boldface type when it isfirst appeared.
Please refer the examples.
Put one table on each page of A4 sized- paper. Prepare them around twice as large
as those printed.
Minimize use of lines.
Use Times New Roman font for characters and numerals in tables.

Color artwork
 Basically manuscript is printed in black-and-white free of charge. Color printing
can be available for a fee.
 When figures submitted are color, it will be published online (J-STAGE) in color.
 When printed manuscript is black-and-white printing and online manuscript is incolor, note that explanation in text corresponds to both black-and-white and color
printings.
References Prepare in accordance with the examples blow.
 Write all author names.
 Write titles of references. When the title is in the absence of English description,
write using roman characters.
 Collate all reference in numerical order cited. Enclose number using within square
brackets.
