Coatings | Issue Cover Articles in the First Half of 2025

1. “Glutamate- and Tartrate-Based Inhibitor Films to Prevent Chloride-Induced Corrosion in Reinforced Concrete: Efficiency of Dry or Hydrated Films via Molecular Dynamics Simulations”
by Giuseppina Raffaini, Michelina Catauro, Fabio Bolzoni and Marco Ormellese
Coatings 2025, 15(1), 37; https://doi.org/10.3390/coatings15010037
Available online: https://www.mdpi.com/2079-6412/15/1/37

Cover Story: Organic inhibitors have been proposed to prevent chloride-induced corrosion in reinforced structures. The homogeneous and stable films on carbon steel and the electrostatic repulsion to chloride ions over time are crucial aspects of their performance. The changing of small organic molecules into passive films by self-aggregation to prevent chloride penetration is important to consider in the design of possible efficient green coatings. The intermolecular interactions of the glutamate- and tartrate-based inhibitor films under dry and hydrated condition are studied via atomistic molecular dynamic simulations.

2. “Preparation and Characterization of Mg-Based Biomaterials with Bioactive Surfaces Functionalized with EU/Gd NPs for Bone Tissue Regeneration Obtained via PEO Process”
by Klaudia Kuźmiak, Łukasz Janus, Aleksandra Sierakowska-Byczek and Julia Radwan-Pragłowska
Coatings 2025, 15(2), 124; https://doi.org/10.3390/coatings15020124
Available online: https://www.mdpi.com/2079-6412/15/2/124

Cover Story: This study focuses on developing magnesium-based biodegradable implants with enhanced bioactivity through surface modification via plasma electrolytic oxidation (PEO) with rare earth ions (Eu/Gd nanoparticles). Magnesium’s light weight, biocompatibility, and bone-like mechanical properties make it a titanium alternative, particularly in pediatric surgery, due to its natural degradation within the body. However, its high reactivity in physiological environments requires surface modification to reduce biocorrosion. Here, the PEO process was used to successfully create a protective coating, limiting biodegradation and magnesium ion release. Characterization tests showed high hydrophilicity, a favorable surface morphology, and excellent biocompatibility, highlighting the potential of modified magnesium implants for biomedical applications.

3. “A Study of the Hall Effect on Doped and Undoped Praseodymium Nickelate Perovskite Thin Films and the Impact of the Reduction Process”
by Alex Misiak, Mufeed Keenari, Yohann Breard, Wilfrid Prellier, Alain Pautrat and Adrian David
Coatings 2025, 15(3), 287; https://doi.org/10.3390/coatings15030287
Available online: https://www.mdpi.com/2079-6412/15/3/287

Cover Story: The following study examines the Hall effect in praseodymium nickelate thin films, focusing on the impact of strontium doping on transport properties. Sr doping enhances transport properties, leading to a transition from semiconducting to metallic behavior. The reduction process and its correlation with transport properties and structural phase change are highlighted. This phase transition induced a change from perovskite to an infinite layer, altering the conduction path from one that is 3D to one that is 2D. Carrier density and mobility are indeed key factors in understanding electronic transport. The infinite layer exhibits semiconducting behavior, with charge carrier concentration and mobility being significantly affected by the reduction process. These characterizations are essential to understanding superconductivity in nickelates.

4. “Novel Bio-Based Formulations for Alkyd Wood Coatings: Effects on Biodegradation and Technical Performance”
by Idoia Etxeberria, Ingemar Svensson, Ana Isabel Díaz and Leire Barruetabeña
Coatings 2025, 15(4), 400; https://doi.org/10.3390/coatings15040400
Available online: https://www.mdpi.com/2079-6412/15/4/400

Cover Story: Bio-alkyd resins were synthetized by replacing phthalic acid with azelaic acid, and were formulated to develop novel wood coatings with enhanced biodegradability. The resulting formulations exhibited good appearance and a natural finish when applied to wood, along with strong adhesion and improved hardness compared to a reference coating. Aerobic biodegradability was assessed in accordance with the ISO 14855-1 standard. This research paves the way for the development of fully bio-based and cobalt-free alkyd coatings combining an improved environmental profile with technical performance properties.

5. “Application of AC-DC-AC Accelerated Aging to Assess the Galvanic Corrosion Risk of Mild Steel Coated with Graphene-Embedded Epoxy Coatings”
by Kazem Sabet-Bokati and Kevin Paul Plucknett
Coatings 2025, 15(5), 501; https://doi.org/10.3390/coatings15050501
Available online: https://www.mdpi.com/2079-6412/15/5/501

Cover Story: Graphene’s incorporation into epoxy coatings raises concerns regarding the galvanic corrosion of metallic substrates due to its high electrical conductivity. In this study, we explore the galvanic corrosion risk of mild steel coated with graphene-embedded epoxy using AC-DC-AC accelerated aging, which simulates real-world delamination by promoting interfacial degradation and ionic transport. Our results showed the minimal risk of cathodic reactions shifting to dispersed graphene within the epoxy matrix, confirming its limited role in galvanic corrosion. While graphene enhanced structural integrity, it weakened adhesion at the steel interface, making the system more prone to delamination. These findings are critical for designing more effective graphene-based coatings, balancing protection and adhesion stability.

6. “The Characterization of Surface Texture in Laser Bamboo Engraving: A Metrological Approach”
by Maria A. Sáenz-Nuño, Cristina Puente and Eva María Rubio
Coatings 2025, 15(6), 624; https://doi.org/10.3390/coatings15060624
Available online: https://www.mdpi.com/2079-6412/15/6/624

Cover Story: Laser engraving is a widely adopted technique for bamboo, yet no standard roughness parameter exists for evaluating surface texture. This study systematically analyzes conventional 2D roughness parameters—commonly used for metals—to assess bamboo surfaces engraved with a pulsed laser (450 nm; 5.5 W) under varying speed and power settings. Using calibrated equipment, we identified the most suitable parameters for accurately characterizing the engraved texture. Unlike previous studies limited by specific materials or laser conditions, we propose two robust 2D parameters—particularly Rz—as reliable indicators of engraving quality across diverse materials and laser setups, enabling consistent, single-measurement evaluations.

Interview with Dr. Rodolpho Váz—Winner of the Coatings Best Paper Award


We are delighted to invite the winner of the Coatings 2024 Best Paper Award, Dr. Rodolpho Vaz, to discuss the review paper “A Review of Advances in Cold Spray Additive Manufacturing”. The paper was published in Coatings (ISSN: 2079-6412) and discussed the examination of the advancements in Cold Spray Additive Manufacturing (CSAM) over the past decade. We hope you enjoy the interview below:

1. Could you please briefly introduce yourself to our readers? Could you share your current research focus and the latest developments in your work?
My name is Rodolpho Fernando Váz, PhD in engineering and applied sciences from the Universitat de Barcelona (Spain), MSc in mechanical engineering from the Universidade Federal do Paraná (Brazil), and BSc in mechanical engineering from the same institution. Over the past 20 years, I have dedicated my career to the development, characterization, and application of wear-resistant coatings, particularly cermets and Fe-based systems. My work has primarily focused on thermal spraying processes, especially arc spraying and high-velocity oxy-fuel (HVOF).

In the last six years, I have also concentrated on advancing Cold Spray as an Additive Manufacturing technique by developing new robotic strategies for building complex geometries and by applying various post-treatments to improve the mechanical properties of fabricated parts, particularly cohesion and strength.

I am currently a researcher at the Center for Thermal Spraying Research (CTSR) at Stony Brook University (United States). My present research focuses on understanding and mapping the cross-effects of HVOF processing parameters, coating stress evolution, and binder composition on the wear performance of WC–Co cermets for severe wear applications.

To date, I have published 33 peer-reviewed papers, delivered 37 conference presentations, and accumulated 486 citations (h-index: 13). In addition, I am the co-inventor on 1 patent, have participated in 17 R&D projects (as researcher, project manager, or principal investigator), and completed over 260 peer reviews of scientific papers, among other academic and professional activities.

2. Could you provide a brief overview of the main content of your award-winning paper?
When I began researching cold spray, I observed that many researchers and institutions were exploring diverse approaches to characterize the deposits, developing strategies for part fabrication, and enhancing the mechanical properties of materials, such as strength. In this context, we—the co-authors—compiled the most relevant and novel findings from the last decade, which resulted in a review article published in Coatings. This work summarizes and discusses the most influential parameters of the cold spray process, including processing parameters (gas temperature and pressure, which determine particle velocity); robotic movement strategies to improve deposit density and geometric accuracy; feedstock material selection (e.g., spherical vs. irregular powders, or small vs. large particle sizes); and post-treatment techniques such as heat treatments and hot isostatic pressing.

Beyond summarizing the results and conclusions reported in high-impact journals by leading scholars in the CSAM field, the article also addresses existing controversies and highlights current knowledge gaps. These aspects must still be resolved to reliably predict and control the capabilities of Cold Spray Additive Manufacturing (CSAM) for producing high-performance components and to support the consolidation of this technique in industrial applications.

3. What do you think are the key elements for writing a successful review paper? Could you describe some challenges and breakthroughs in your research field?

I see the very first step as reading as many papers as possible, without being limited to researchers who share the same opinions and concepts as mine. Beyond focusing only on my research theme, exploring other coating techniques and materials—whether directly related or not—can broaden my background and create bridges between previously unconnected subjects. When reading, it is essential to maintain a critical perspective by asking “Do the authors’ arguments make sense? What is missing from this work? How could it be complemented? Are there other studies that address these gaps?”. These questions are fundamental when preparing a review-type paper. Compiling the work of other authors, merging their ideas with constructive criticism, and proposing trends and future directions to fill existing gaps is one of the greatest challenges for review paper writers.

4. How does it feel to receive the Best Paper Award? What does this recognition mean to you?

It was a great honor to receive this recognition from Coatings. Writing an impactful paper was a challenging task, and this achievement would not have been possible without the invaluable contributions of my colleagues and the reviewers, who helped shape the first draft and significantly improve the manuscript during the review process. Their support made the work much stronger.

Beyond the award itself, it is deeply rewarding to see that this paper has been useful to many researchers, as reflected by the more than sixty citations it has already received. Such scholarly recognition, combined with the distinction of receiving an award from a prestigious journal like Coatings, provides strong motivation to continue advancing knowledge and contributing to society through the publication of high-quality research.

5. In your opinion, which research topics do you think will be the most popular in the field of coatings and cold spray technology in the coming years?

I have observed that the development of hybrid deposition systems has become a prominent research trend. Examples include atmospheric plasma combined with arc spraying to produce harder and denser wear-resistant coatings, or laser-assisted cold spraying to enhance particle cohesion. The concept of hybrid systems opens the door to countless possibilities, with synergies that remain largely unexplored by “merging” the advantages of two or more fundamentally different deposition techniques.

In addition to advances in processing, the development of new materials also continues to be a major trend. High- and medium-entropy alloys, for instance, offer exciting opportunities. Research on in situ HEA formation during deposition could significantly reduce the time and cost associated with producing specialized powders, while yielding coatings with exceptional corrosion and wear resistance.

6. What attracted you to submit your work to Coatings? Could you share your experience of submitting to this journal?

Regarding my choice of Coatings, firstly, it is a journal dedicated to my research topics, and my work fits perfectly within its scope. Secondly, the submission, review, proofreading, and publishing process in Coatings—and MDPI journals in general—is much faster than in many other leading journals, which aligns with my sense of urgency to make my work visible and accessible. Thirdly, Coatings has a growing reputation and impact factor, both of which are important for my academic profile and career development. Finally, and no less importantly, Coatings has consistently published high-quality works with clear scientific contributions in thermal spraying processes and cold spray additive manufacturing, which have been the core of my research for decades. For these reasons, I plan to continue publishing many more works in Coatings.

7. What advice and insights would you share with young scholars, particularly when it comes to selecting research topics and maintaining persistence?

Young scholars—almost all of them—need to cultivate greater patience and humility. Advisors, colleagues, professors, lab technicians, students, and everyone in academia have something valuable to contribute to improving the quality of our work. Whether it is a tip, a criticism, or assistance in interpreting test results, it is always important to listen carefully and avoid arrogance.

This attitude also applies to the feedback we receive from peer reviewers when submitting a manuscript to a journal. I prefer to view their comments not as “criticisms,” but rather as “recommendations” aimed at strengthening our work. We must approach these remarks as opportunities to enhance the quality of our research, not as an underestimation of our effort.

In summary, the entire scientific community shares the same goal: to bring out the best in our work for the advancement of science.

8. As the recipient of this award, could you share your feelings and whom you would like to thank?

I would like to thank my colleagues who contributed to the development of this work and assisted in writing the first draft of the manuscript: Andrea Garfias, Vicente Albaladejo, Javier Sánchez, and Irene García Cano from the Thermal Spray Center (CPT) at the Universitat de Barcelona. I am also grateful to the four anonymous reviewers for their valuable recommendations and suggestions, which significantly improved the quality of the manuscript, as well as to the editors of the Advanced Cold Spraying Technology Special Issue—Wen Sun, Xin Chu, and Adrian Wei Lee Tan—for their support.

9. What are your views and expectations regarding the open access model of publishing?

I believe that free access to high-quality scientific papers greatly facilitates the diffusion of knowledge, benefiting both scholars and society at large. Open access allows anyone to read the most recent advances in science without financial barriers. Naturally, the costs of publication must still be covered, and in the open access model, this responsibility falls on the authors, who often rely on university support or project funding to cover publication fees. Despite this challenge, I see open access as the most effective way to publish scientific research and disseminate knowledge broadly. Long live open access!

MDPI is already the leading OA publisher in South Korea, yet challenges and misconceptions around OA and APCs remain. Visits like this one, along with the ongoing efforts of our Seoul office, are important to building understanding, trust, and long-term relationships with the local academic community.

A big thank-you to our colleagues in Seoul for their warm hospitality, professionalism, and energy! Our new office is well situated, staffed, and ready to grow. This visit marked an important step forward in our continued mission to support global research communities and advance Open Science.

Inside MDPI

Preprints.org Reaches 100,000 Preprints: A Major Milestone for MDPI and Open Science

In case you missed it, Preprints.org recently surpassed 100,000 preprints posted. This is a major milestone for our platform and one worth celebrating.

Preprints are a key pillar of the Open Science movement, which promotes transparency, equity, and faster knowledge-sharing through initiatives such as Open Access, Open Data, Open Source, and Open Peer Review. The benefits of Open Science extend beyond researchers, as they support funders, educators, policymakers, and the public in advancing discovery and innovation.

What is behind the 100,000 preprints milestone?

Since its launch in 2016, Preprints.org has grown into one of the world’s leading preprint platforms, now ranked fifth globally by publication volume.

More than 350,000 researchers have contributed, helping shape this dynamic and collaborative space for sharing early-stage research across all disciplines.

“Preprints.org has grown into one of the world’s leading preprint platforms”

Some quick facts worth noting:

  • About 56% of the preprints on Preprints.org are later published in peer-reviewed journals.
  • The platform is now indexed in Web of Science (Preprint Citation Index), Europe PMC, and Crossref, helping improve visibility and trust in the preprints shared.
  • Recent upgrades – including a revamped website, new features such as search subscriptions, curated reading lists, and community feedback tools (PREreview) – show our commitment to developing Preprints.org in line with researchers’ needs.

This growth and progress would not be possible without the dedication of the Preprints.org team, our Advisory Board members, screeners, and colleagues across MDPI who support the platform’s development. This milestone is a reminder of our shared mission: to accelerate scientific communication and build a more open, transparent, and inclusive research ecosystem.

I’m excited to see what’s ahead as we approach Preprints.org’s 10-year anniversary in 2026!

Coming Together for Science

Malaysia Media Roundtable: Educating on Open Access and MDPI’s Presence in Southeast Asia

At the end of June, I had the opportunity to participate in a strategic media roundtable in Kuala Lumpur, focused on raising awareness about the importance of Open Access (OA) and on MDPI’s growing presence in Southeast Asia.

We welcomed five Malaysian media outlets for an engaging private session that included presentations and open discussion.

I gave an overview of the benefits of Open Access, MDPI’s global developments, and our collaborations in Malaysia.

My colleague Yu Nwe Soe (Public Relations Specialist), presented on our editorial process, helping to clarify how MDPI supports authors and maintains research quality.

We were also joined by two local Editorial Board Members (EBMs) who offered first-hand insights into their experiences working with MDPI and how OA has shaped their publishing choices.

The discussion covered a range of questions from the press, from OA publishing models to editorial standards, and highlighted MDPI’s unique contribution to accelerating scientific communication in the region.

As the leading fully OA publisher, we see it as our responsibility to continue educating research communities and the broader public on the impact of OA, especially in emerging and high-growth academic markets.

Spotlight on Malaysia

Malaysia continues to rise as a regional research hub, with five universities ranked in the global top 200 and 11 subjects in the global top 50. In 2024, Malaysia ranked 2nd in Southeast Asia in total publication output, 10th in Asia, and 25th globally.

MDPI’s presence in Malaysia:

  • Over 21,000 research articles published to date from Malaysian institutions
  • More than 1,100 articles published in 2024 alone
  • In the period 2020–2024, 54% of Malaysia’s total publications were OA
  • 36 EBMs from Malaysia, across 27 MDPI journals
  • Around 100 conferences sponsored in Malaysia in the past five years
  • MDPI is hosting the 2nd International Conference on AI Sensors and Transducers in Kuala Lumpur (29 July- 3 August 2025)

Media Coverage & Editorial Voices

Following the roundtable, we saw positive coverage across several local outlets, with articles highlighting MDPI’s role in empowering Malaysian researchers. Notable pieces included:

Our local EBMs also shared their perspectives:

Prof. Denny Ng Kok Sum (Sunway University, EBM of MDPI journal Processes) and Prof. Lee (EBM of MDPI journal Bacteria) share their experiences with MDPI and the role Open Access plays in their publication decisions.

“We see it as our responsibility to continue educating research communities on the impact of OA”

“I didn’t want my work stuck behind a paywall.”
— Prof. Denny Ng Kok Sum, Sunway University, Processes Editorial Board Member

“Open Access opens doors for collaboration and visibility, especially in fast-developing regions like ours.”
— Prof. Lee, Bacteria Editorial Board Member

This roundtable marked another step in building trust, understanding, and collaboration in Southeast Asia. A big thank-you to the MDPI Malaysia team and all those who contributed to the event’s success.

Closing Thoughts

MDPI Signs First North American Agreement with Canadian Consortium

We are proud to announce a major milestone for MDPI Canada and an important step forward for OA in North America.

In July, our Toronto office finalized MDPI’s first North American consortium agreement with the Federal Science Libraries Network (FSLN). This is a significant achievement that strengthens our expansion in Canada and reinforces our global commitment to supporting Open Science.

This two-year agreement gives Canadian federal agencies access to MDPI’s IOAP, including discounted article processing charges for affiliated researchers across our portfolio of over 475 OA journals. It lowers barriers for Canadian scientists to share their work more openly and reach a global audience.


Ryan Siu, Institutional Partnerships Manager at MDPI.

“The Open Science landscape in Canada is rapidly evolving, with the Tri-Agency Open Access Policy set for renewal by the end of 2025. This reflects ongoing efforts to foster greater scientific transparency and accessibility at a national policy level,” says Ryan Siu, Institutional Partnerships Manager at MDPI.

“Our new agreement with FSLN represents our shared commitment to further these efforts and foster wider readership. By aligning with these initiatives, we make progress towards research that’s both inclusive and impactful, benefiting local and global communities alike.”

Participating FSLN institutions include:

  • Agriculture and Agri-Food Canada
  • Environment and Climate Change Canada
  • Health Canada
  • National Research Council Canada
  • Natural Resources Canada

By partnering with some of Canada’s largest science-based agencies, we reaffirm our goal of advancing OA across continents. We look forward to developing our support for Canadian researchers and continuing to drive progress in Open Science across North America and beyond.
