How long did you invest in giving a repair?

I submitted three articles many years ago, and they were quickly accepted after revisions based on reviewer comments. I remember that there were no fees for publication at that time, but I recently heard that there are now page charges. Is this true? Can any authoritative figure clarify this?

May I ask if the journal coverage fee can still be selected this year?

Actually, it is still free, and you can choose for the journal to cover all expenses. Some papers are processed quickly, while others are slow, depending on which associate editor is handling them

Officially open source, but actually free of charge, the editor-in-chief will give you a deduction code to cover all expenses. The processing speed depends on the associate editor in different directions, the associate editor in the direction of wellbore fluid workflow processes papers very quickly

The processing speed of this journal is very slow, and now it is an open access journal that requires a fee of $2100. It's unbelievable - slow, low impact factor, and expensive. It is possible that fewer and fewer people will submit to this journal in the future

Do I need to pay the publication fee? I was accepted for publication this year and I'm wondering if I need to pay the fee. Can I choose to pay or not? Please help me with this

Is this journal charging publication fees? Because I have previously accepted an offer and already paid the publication fees, can I choose not to pay?

Currently, journals still do not require authors to pay publication fees. When the article is modified to be almost acceptable, the editor will provide the author with the same modification advice in the revision letter. You only need to select the journal for publication!

and enter the following code in the field 'I have a BMC membership account number' : JS-JPPT-PEPT-0921
The journal will then cover your APC if you are not covered by another OA agreement

During this additional administrative stage, you will need to consent to our OA License to Publish (LTP), and will also be shown an APC payment window. If you wish to have the APC covered by the journal, please select the option 'I believe that I am covered by a BMC/SpringerOpen Membership Account and wish to request institutional payment or discount...' option on the APC agreement page

As you first submitted your manuscript before October 1st 2021, when we announced the transition to full Open Access, there will be an additional administrative stage where you will need to answer some questions before your manuscript can be submitted

Did you pay the layout fee in the end?

Can I choose to pay for the journal cover fee after my article is accepted? I didn't choose to pay by institution when I started submitting. Can I still choose to pay for the journal now? Looking forward to your advice!

Hello, may I ask if you haven't received the invoice for the journal? When was the initial submission of the manuscript? Is it really free of charge?

The editing process is fast. The first review took 53 days, and the feedback included 1 minor revision, 1 major revision, and 1 rejection. The editor requested a major revision. The second review took 18 days, and the feedback was for minor revisions. In addition to technical issues, the editor wanted improvements in language. After submitting the revised manuscript, it took a week to receive acceptance. It seems that this journal does not require any publication fees. I submitted my paper in December 2021, but the editor mentioned that papers submitted before October 1, 2021, can choose to pay Open Access fees. As a result, I did not have to pay any fees. Have any of you encountered a similar situation? It would be great if the journal covers the fees.

Submit by the end of August, receive major revisions in mid-October, and be accepted for publication after submitting the revised draft by the end of November.

The text translates to:

"I submitted the manuscript at the beginning of November and received major revisions in the review comments yesterday. The editor-in-chief said that I don't need to pay the page fee, and the journal will cover it. They also provided me with a code. However, I actually didn't submit it before October 1st. It seems that the journal hasn't started charging authors yet. As you first submitted your manuscript before October 1st 2021, if you wish to have the APC covered by the journal, please select the option 'I believe that I am covered by a BMC/SpringerOpen Membership Account and wish to request institutional payment or discount…' option on the APC agreement page, and enter the following code in the field 'I have a BMC membership account number': JS-JPPT-****-****."
