This is an example document for the achemso document class, intended for submissions to the American Chemical Society for publication.
For more information on preparing your manuscript for submission to ACS Publications, please see their resource center.
Use the psfrag package to replace strings in EPS images, so that they are typeset with the same body font as your LaTeX document. Note that your project needs to be compiled with the LaTeX dvipdf engine. To configure this, after creating a new project, click on the Overleaf menu icon above the file list panel, and make sure the "Compiler" setting is set to "LaTeX". (The sample image is taken from the psfrag package.)
This is an example of the iopart document class, and contains details on how to prepare and submit your articles for publication in an IOP Publishing journal. Note that IOP Publishing journals do not require TeX submissions to use this document class, other templates can be used.
If you'd like to write an IOP Publishing article, you can use this example document as a template and change the main article text to suit - simply click the button to get started.
Alternatively you can also just upload the iopart.cls file available from IOPP (see https://publishingsupport.iopscience.iop.org/questions/latex-template/) to any document you've already created, and change the document class to iopart to convert it to the style of this template.
