Announcements

Separations (ISSN: 2297-8739)—formerly Chromatography—is an international, scientific, peer-reviewed, open access journal on separation and purification science and technology in all areas of chemical, biological, physical science, and separation performance published monthly online by MDPI. The Central European Group of Separation Sciences (CEGSS) is affiliated with Separations, and their members receive a discount on the article processing charges.

In order to support the scientific community and contribute to the faster distribution of important scientific research, Separations has cooperated with various academic conferences and is now seeking cooperation with additional academic conferences. The journal is open to a diverse range of collaborations, such as media partnerships, awards, exhibitions, and publications.

The scope of Separations includes, but is not limited to, the following:

Theory and methodology:

• Theory of separation methods;
• Sample preparation;
• Instrumental and column developments;
• Trace purification technology;
• Electrochemical separations;
• Solid phase extraction;
• New separation methodologies, etc.

Equipment and techniques, novel hyphenated analytical solutions:

• Significantly extended by their combination with spectroscopic methods and, in particular, mass spectrometry;
• Hyphenated instrument configurations, e.g., LC–MS;
• Novel analysis approaches and applications to solve analytical challenges which utilize chromatographic separations as a key step in the overall solution, e.g., high- and low-resolution chromatography.

Computational modeling of separations for the purpose of fundamental understanding and/or chromatographic optimization:

• Instrumentation miniaturization;
• Automation;
• Method development and validation;
• Instrument and method qualification and validation.

We welcome consultations with any conferences related to Separations. If you are interested in collaborating with Separations, please contact us at separations@mdpi.com.

Stanford University has recently published an update of the list of the top 2% most widely cited scientists. The time node of the statistical data of this list is from 1960 to 2022, and it is divided into two lists: "Lifetime Scientific Influence Ranking" and "2022 Annual Scientific Influence Ranking". The "Lifetime Scientific Influence Ranking" counts the comprehensive influence performance of scientists during their careers, and the "2022 Annual Influence Ranking" focuses on highlighting the academic influence of scientists in the previous year. This ranking, considered the most prestigious worldwide, is based on the bibliometric information contained in the Scopus database and includes more than 200,000 researchers from the more than 10 million scientists considered to be active worldwide, with 22 scientific fields and 176 subfields taken into account.

We are pleased to share that 72 Editorial Board Members from MDPI’s journal Separations (ISSN: 2297-8739) were featured in Stanford University World’s Top 2% Scientists list in 2022.

The latest Stanford rankings reflect the significant influence and research excellence of the scientists, who are committed to furthering their knowledge for the benefit of the world.

We would like to congratulate our Editorial Board Members on their excellent achievement and thank them for their immense contribution to the scientific progression and development of Separations.

Peer Review Week began 19 September 2022 under the theme of “Research Integrity: Creating and Supporting Trust in Research”. Through various blog articles, podcast, and webinar, we discussed this crucial subject throughout the week, celebrating the essential role peer review plays in maintaining research quality.

To begin, we held a Webinar on the topic. Professor Peter W. Choate and Dr. Emmanuel Obeng-Gyasi joined Dr. Ioana Craciun, one of MDPI’s scientific officers, for an in-depth discussion.

We invite you to view the event recording:

During the week, the MDPI Blog in a series articles highlighted how good Peer Review safeguards research integrity. The following topics were covered:

• Peer Review Week 2022
• Research Integrity
• What We’ve Learned About Peer Review Reports
• 4 Steps to the Perfect Peer Review Report
• How to Write the Perfect Peer Review Report: An Interview
• Inviting Great Peer Reviewers

In a new edition of Insight Faster, an MDPI podcast, we were delighted to talk to the co-chairs of the Peer Review Week committee, Jayashree Rajagopalan (Senior Manager of Global Community Engagement for CACTUS) and Danielle Padula (Head of Marketing and Community Development at Scholastica) to get their take on this year’s event and its related topics.

You can find the Podcast here.

We hope you enjoy the contents!
