Full Fee Waiver – Currently Active

Periódico Tchê Química currently offers a full fee waiver for an indefinite period to all authors. Since August 2023, we have operated under the Platinum Open Access model, ensuring free access to reading and free publication for all research. This policy eliminates financial barriers for both authors and readers, promoting equitable global sharing of scientific knowledge.

• Institutional Support: Collaborations with universities and research organizations are publicly acknowledged, with no influence on editorial decisions.
• Individual Contributions (Conflict Management): Donations from the scientific community are welcome but subject to strict ethical guidelines. Authors must wait 6 months after publication to contribute, ensuring editorial independence. Anonymous donations are prohibited. No donations are accepted for manuscripts under review.
• Transparency: All financial flows, including service contributions and donations, are detailed in annual reports. Funds support platform maintenance, peer review management, and digital preservation.

Our Position on Public Funding

Periódico Tchê Química is an independent publication and operates without receiving or requesting government funding for its activities or goals. This decision is grounded in clear ethical principles:

• Direct Responsibility: We believe that the costs of scientific publishing, when necessary, should be borne by the professionals who directly benefit from publications and their research institutions.
• Fiscal Equity: Accepting government funds derived from Brazilian taxpayers would constitute an advance and compulsory charge on the publication of any manuscript. We do not consider it morally appropriate for all citizens to compulsorily pay for research that directly benefits only a segment of the population.
• Editorial Autonomy: Financial independence from government ensures full editorial freedom and shields us from political or bureaucratic pressures on our scientific decisions.

When Fees May Be Implemented

While we currently operate with full fee exemption, we recognize that the journal’s financial sustainability is directly tied to editorial workload volume. Should fee implementation become necessary in the future, this decision will be based on objective and transparent criteria:

Determining Factor: Manuscript Volume

• Low Volume (a few dozen manuscripts/year): No fees are required. Volunteer editorial work and donations are sufficient to maintain operations.
• High Volume (hundreds or thousands of manuscripts/year): Implementation of Article Processing Charges (APCs) may become necessary to ensure the journal’s financial viability, guaranteeing resources for:
  • Adequate technological infrastructure
  • Professional manuscript management system
  • Expanded editorial support
  • Long-term digital preservation
  • Indexing and visibility services

Transparency Commitment

Any fee implementation will be clearly and transparently declared on this page with a minimum advance notice of 6 months. The introduction of fees will be communicated to the entire scientific community through multiple channels, including:

• Clear notice on the journal website
• Email notification to registered authors
• Explanatory editorial in the issue prior to implementation
• Complete breakdown of fees and justifications

Donation Procedure

1. Express your intention: Clearly state in your cover letter that you wish to make a donation to the journal.
2. Await instructions: Our team will provide the means to complete your donation, typically via PayPal or bank transfer.
3. Ethical Guidelines:
   • Anonymous donations are not accepted
   • Authors with manuscripts under review cannot donate
   • After publication, please wait 6 months before contributing
   • All donations are publicly acknowledged (with donor permission)

Important: Periódico Tchê Química offers optional support services for researchers, while maintaining our core commitment to Platinum Open Access publishing. These services are voluntary contributions, entirely separate from the publication process, with no mandatory fees. Researchers may choose to use these services or handle such tasks independently through other channels.

Available Services

Key Principles for Optional Services

• No service affects editorial decisions or publication timelines
• Authors with financial constraints retain full access to publication
• No refund policy, as there are no mandatory fees
• Pricing reflects service complexity and market competitiveness
• Transparency is prioritized: services are optional, with no hidden costs
• Editorial integrity remains paramount; financial considerations never influence peer review

Important Note: Choosing the appropriate statement is the authors’ responsibility. Including one of these statements in the manuscript is mandatory and will be verified during the editorial review process.

Periódico Tchê Química reaffirms its commitment to the democratization of science through barrier-free access, rigorous ethical practices, and high-quality academic exchange. Together, we promote global scientific innovation and collaboration, always maintaining our editorial independence and commitment to scientific excellence.
