MDPI Books recently released Book Builder, a new online tool to conveniently arrange, design and produce an eBook from any content published in MDPI journals. Book Builder offers two functions: on the one hand (1) Selections, available to every registered user of MDPI; on the other hand (2) Special Issue Reprints, which can be used exclusively by Guest Editors of Special Issues.

Selections

In just a matter of a few clicks, all users are now able to assemble books from MDPI articles and receive instantaneous feedback in the form of a fully produced and compiled book (PDF), which can be downloaded or ordered as print copy. Selections can include any paper published with MDPI, picking and combining content from different journals and special issues.

This way, the user may for example choose to compile an ebook focusing around a particular topic, or assemble articles from a group of others.

We invite you to make yourself familiar with the new tool! The Book Builder can be found here: https://www.mdpi.com/books/book_builder.

Special Issue Reprints

The Book Builder allows Guest Editors of MDPI journals to create a reprint from a successfully completed Special Issue or Topical Collection in book format. If you are a Guest Editor for an MDPI journal, you can use the new tool  to create an PDF document which includes all articles published in the Special Issue as well as a book cover and table of contents.

For Special Issues containing a minimum of 5 articles, the Guest Editor can request its publication on the MDPI Book platform. Published reprints are assigned an ISBN and DOI.

In addition to the PDF copy of the Reprint Book, as a token of our gratitude, MDPI offers every Guest Editor one (1) complimentary print copy (via print-on-demand). All contributors benefit from a discount on orders of any additional print copies, to share with colleagues or libraries or others.

In June of this year, MDPI will celebrate the 25th anniversary of its foundation. To mark this significant milestone, we have created a 25th Anniversary page on our website that evokes the development of our company over the past quarter-century.

MDPI has been a pioneer of Open Access publishing ever since the concept was first created.

In a wide-ranging interview, our CEO Delia Mihaila reflects on the company’s 25th anniversary and its contribution to the world of scientific publishing.

Delia considers how MDPI has evolved since starting life in 1996 as a visionary ‘project’ run out of an apartment in Basel, Switzerland, by Dr. Shu-Kun Lin. A chemist who was passionate about the long-term preservation of rare chemical sample, Dr. Lin was determined to help scholars publish their findings as quickly as possible and make their research results available to as wide a readership as possible worldwide. That determination remains unchanged 25 years later.

Today, MDPI is an international organization with over 4,000 employees based on three continents and in ten countries, and ranks among the world's top four academic publishers.

MDPI's mission is to accelerate access to new scientific research, delivering insight faster for researchers worldwide. Read more here about the company's remarkable success story and what the Open Access publishing model can offer the global scientific community.

At MDPI, we strive to make your online publication process seamless and efficient. To achieve this, our team is continuously developing tools and features to make the user experience useful and convenient.

As the number of academic papers continues to grow, so does the need to analyze and work with them on a large scale. This prompted us to design a new feature aimed at helping researchers find journals that are relevant to their publication by matching their abstract topic. In this regard, we designed a similarity model that automatically identifies the most suitable academic journals for your paper.

We are pleased to introduce Journal Selector, a new feature that measures similarity in academic contexts. By simply entering the title and/or abstract into our Journal Selector, the author will see a list of the most related scientific journals published by MDPI. This method helps authors select the correct journals for their papers, highlighting the time of publication and citability.

The methodology is known as representation learning, where words are represented as vectors in hyperspace. Representation helps us differentiate between different concepts within articles, and in turn, helps us identify similarities between them.

We used an advanced machine learning model to better capture the semantic meanings of words. This helps the algorithm make better predictions by leveraging scientific text representation. In turn, this ensures high precision, helping authors decide which journal they should submit their paper to.

The goal is to support authors to publish their work in the most suitable journal for their research, as fast as possible, accelerating their career progress.

1. Could you briefly introduce yourself to the readers?

My name is Junsuk Rho, I am currently a Mu-Eun-Jae endowed chair Associate Professor with a joint appointment in the Department of Mechanical Engineering and the Department of Chemical Engineering at Pohang University of Science and Technology (POSTECH), South Korea.

2. What does your current research involve, and why did you choose this research field?

My research is focused on developing novel nanophotonic materials and devices based on fundamental physics and experimental studies of deep sub-wavelength light-matter interactions. Specifically, I am working on metamaterials, plasmonics, photonic crystals, topological photonics. Recently, the wavelength regime has expanded to longer wavelengths, such as acoustic and elastic frequencies. I saw the news that an invisibility cloak may be creating through the application of metamaterials. This is the reason why I want to study this for my Ph.D. Such metamaterials will be able to realize invisibility cloaks, super-resolution imaging, acoustic black holes, hologram displays and so on.

3. Which research topics do you think will be of particular interest to the research community in the coming years?

Quantum optics, flexible opto-electronics, photonic chips for diagnostics, and single-digit-nanometer fabrication to overcome the current semiconductor industry problems.

4. Have you ever encountered any difficulties when conducting research? If so, how did you overcome them?

Everyday... this is related to question number five. Have patience, persevere with the research until you make a breakthrough, try not to become depressed and frustrated with your research if things do not go as planned first time around.

5. What qualities do you think young scientists need?

Patience, a positive mind for failure (e.g., individuals who do not let the failure of experiments depress or frustrate them, but instead try the same thing the next day!), and people who keep up to date with the current scientific trends.

6. Micromachines is an Open Access journal. How do you think Open Access impacts the authors? 

Open access journals allow more readers to read the papers, which is extremely helpful in sharing the result with different communities. However, with the limited funding (especially for junior researchers), it can sometimes become a burden. So, support for junior researchers is necessary. In terms of this, MDPI does a very good job in providing financial support and waiving fees for junior researchers.
