Author Guidelines



Vietnam Journal of Science and Technology (VJST), established in 1962, is a peer-reviewed journal published by Vietnam Academy of Science and Technology. The VJST publishes 6 issues per year, in February, April, June, August, October, and December. Special issues are also welcome, but interested guest editors are requested to follow the journal rules including proposal submission and peer-reviewing.

Vietnam Journal of Science and Technology publishes research articles and review papers, as well as short communications related to Science and Technology of: (A) Natural Products, (B) Materials, (C) Environment, (D) Electronics & Telecommunication, and (E) Mechanics & Engineering.

Manuscript preparation

Authors are encouraged to download a VJST-Template to refer for paper preparation before submission to the journal.

Manuscripts  should  generally  be  arranged  in  the  following  order:  title  page,  abstract,  introduction,  materials  and methods, results and discussion, conclusion, acknowledgements, and references. Papers in the technological fields may follow rules different from the above but must remain logical.

Title page: The  first  page  of  any  manuscript  shall  include  the  title,  name(s)  of  authors,  their  institutional  affiliations  and addresses, city and country (zip codes, if applicable), email address of corresponding author.

Abstract: The abstract is a concise, abbreviated version of the paper which tells the reader whether the paper is worth reading at all; it must therefore be informative with respect to aim, methods, procedures, results, discussion, and conclusion.  An abstract should not exceed 250 words.

Keywords: Three to five keywords (separated by comma) that best describe the paper are recommendable.

Introduction: The  introduction  should follow the key words and should be as brief as possible; it should concern itself with a clear justification for the work  undertaken  and  the  underlying  theory  and  hypothesis;  a  short  review  of  literature  in  the  field  of study  is obligatory although any exhaustive review properly belongs to the discussion section.

Materials and Methods: This section describes concisely the methodology/procedures employed so that anyone wishing to replicate the trial can do so and obtain comparable results. Provide  sufficient  detail  so  as to  remove  any  possible  ambiguities  with  respect  to design, treatments,  measurements,  analysis,  etc. Where methods employed are commonly known in a given field details should be omitted and the reference given instead. Modifications to known methodology must however be clearly described and explained.

Results and Discussion: This section describes clearly the observations made and their concise interpretation. Results should be presented in tables and/or figures whenever possible, but should be clearly explained in the text taking care to avoid unnecessary repetition of tabular data. Information presented in tables should not be repeated in figures, or vice versa. Standard deviations/errors help the reader to follow the trend of results and should be supplied whenever appropriate. The discussion should include references to earlier or contemporary literature relevant to the topic studied; this way, a reviewer can decide on the merits of the manuscript.

Formulas, illustrations and figures: Mathematical symbols and formula should be typed clearly and all equations must be numbered consecutively on the right-hand side of each equation. VJST prints its papers in black. So, if colored illustrations or/and figures are submitted, be sure that they will be well resolved in the printed version.

ReferencesEach reference in the ‘Reference List’ should be numbered according to the order of appearance in the main text. References in languages other than English must be referred to by an English translation. References to a published paper must include the names of all the authors, the title of the paper, the (or abbreviated) journal name, the volume in boldface, the issue number in parentheses, the year of publication in parentheses, and the first-last pages number or the article number. References to a book must include the names of all the authors, the title, the name of the publisher, the place of the publisher and the year of publication in parentheses. References to conference/workshop proceedings must include the names of all the authors, the name of the conference/workshop, the name of the publisher, the year of publication in parentheses and the first-last pages of the cited work.  References to a preprint must include the names of all the authors, the source of the preprint and the year of publication in parentheses.
