Why Article processing Charges (APCs)?
As a rule of open access publishing and because of the reason that scientific community and the general public can unlimitedly and immediately access all content published in our journals for free as soon as it is published on the Internet, we kindly request all our dear authors to help us to compensate a part of our economical matters. This means that the journal does not have any income from selling subscriptions to print or online versions of its journals or from charging "pay-per-view" fees. Therefore, we need to defray its editorial and production costs by collecting article processing charges from authors' institutes or research funding bodies. Besides, journal charges—if calculated per page—are much lower than the revenues per published page that traditional, subscription-based academic publishers can generate. Paying the article processing charge in an Open Access journal is a replacement with the normal subscription charges used by most journals and allows journals to make the full text of every published article freely available to all interested readers.

Which journals have APC?
There are 3 ways to find out that which journal requires payment (article processing charges):
To know the exact fees read the related page in our journal website (Journal Website > Help > Instruction for Authors > Payment Instructions > Article Processing Charges)
Acceptance Fee (AF)
Author(s) agrees to pay the required "Acceptance Fee" in the first step of submission (see below image). They have to act just based on the journal policy and regulations after accepting their articles in the journal. Those manuscripts which are still remained in the "Pending" step of payment and need payment, are not allowed to be submitted elsewhere. It means that without payment, a manuscript is not allowed to submit in any other journals.
How to order AF?
Acceptance fee will be ordered only via journal website when your article is primarily accepted by EIC. Just wait till this phase, then you will be able to pay it online.
Corresponding Author is able to pay "Acceptance Fee". To pay, s/he must sign in to the journal website and refer to "Needs Payment" menu under "With a Decision" (see below image)
Premium Publishing Fee (PF)
The accepted articles go to the waiting list for publishing and based on a timely manner plan will be published. If a speedy publication process is required, the journal offers a premium publishing model in which selected accepted articles may be paid to publish at the first possible issue. This is entirely optional - if you do not wish to pay for a premium publishing process, your article will be published based on the normal editorial selection. If you opt for premium publishing, you are guaranteed: publication of your paper in one of the earliest coming issue after payment of the fee.
How to order PF?
To take advantage of this, authors must pay a non-refundable Premium Publishing Charge (PF). The PF should be paid using the journal website and under each submission ID.
>>> Do the same as we explained in details for AF (refer to top).
If you have any question regarding PF, ask us via technical support of our journal. We reserve the right to refund the fee and process the article in the regular publishing track if we are unable to meet the deadline due to a delayed publishing or other issues beyond our control.
