Special issue: Measurement of the environmental impact of materials (2021)
Throughout their life cycle—from production, via usage, through to disposal—materials and products interact with the environment (water, soil, air). At the same time, they are exposed to environmental influences and, through their emissions, have an impact on the environment, people, and health. Accelerated experimental testing processes can be used to predict the long-term environmental consequences of innovative products before these actually enter the environment. The aim of this Special Issue of the journal Materials is to publish original research and review articles as well as short communications tackling the problem of reliable environmental measurement methods and reporting exemplary case studies.
Special issue: Alkali-activated materials and geopolymers in ceramics and beyond (2021)
Geopolymers and alkali-activated materials have emerged as a complement, and partly as an alternative, to traditional materials in various applications, such as traditional ceramics, energy saving, waste management, building construction, and filtration. These new materials can play an important role in mitigating climate change and promoting a circular economy, which is one of the reasons why they are being actively researched in many laboratories around the world. Open Ceramics, the official, peer-reviewed, Open Access journal of the European Ceramic Society, is dedicated to foster this research and is compiling a Special Issue with the title “Alkali-activated and geopolymer materials in ceramics and various applications”. The aim of this Special Issue is to promote new applications, the use of previously underused raw materials, and in particular a better understanding of the chemical and mechanical behavior of these materials. The scope of the Special Issue includes, but is not limited to, research on the following topics: - valorization of previously underused raw materials - a better understanding of established raw materials - detailed spectroscopic characterization of alkali-activated materials and geopolymers to elucidate their phase assemblage - the mechanism of formation of the phase(s) that comprise these binders - control of their mechanical properties - the effect of fillers/aggregates on their mechanical properties - their durability under various conditions and the underlying deterioration mechanisms - special applications and recycling-related considerations.
Proceedings of the third international conference on materials engineering and applications (ICMEA 2020) (2020)
The Third International Conference on Materials Engineering and Applications (ICMEA 2020) was held from 6 to 8 January 2020 in Ho Chi Minh City, Vietnam. The conference provided a wide platform for the participants to communicate with each other and to share their research achievements. The distinguished keynote speakers, on the other hand, created a motivational academic atmosphere through the presentation of their outstanding research outputs. So, on behalf of the organizing committee, we are pleased to present this volume, containing selected contributions to this conference, of authors based in the industry, research institutes and universities. You will find that a variety of subjects around materials is being covered in these proceedings, including material's science, processing and properties, as well as measuring methods and applications. The selection of papers for this volume, we must recognize, was indeed a challenging endeavor for the about fifty specialized researchers that voluntarily took their time for the reviewing process for this IOP Conference proceedings volume. While we appreciate the efforts of all the author that submitted papers for this conference as well as the key role of the reviewers, we express our gratitude to all the members of the supporting staff, for their enduring effort to make the conference process a smooth one, and to the proceedings editing team, whose time and talent created the present volume from scratches.

Special issue: Laser-induced periodic surface nano- and microstructures for tribological applications (2020)
Laser material processing is an emerging technology that generates surface functionalities on the basis of optical, mechanical, or chemical properties. In the form of laser surface texturing (LST), it has attracted a remarkable amount of research to tailor surface properties towards various tribological applications. The main advantages of this single-step, laser-based technology are the contactless machining, featuring a high flexibility, efficiency, and speed, along with the excellent quality of the processed products. LST can be applied precisely localized to sub-micrometric areas, but, via laser beam scanning, it is also feasible for structuring large surface areas at the square meter size. This Special Issue focuses on the latest developments concerning the tribological performance of laser-generated periodic surface nano- and microstructures and their applications. This includes the laser-based processing of different surface patterns, such as “self-organized” laser-induced periodic surface structures (LIPSS, ripples), grooves, micro-spikes, hierarchical hybrid nano-/micro-structures, microfeatures generated by direct laser interference patterning (DLIP), or even dimples or other topographic geometries shaped by direct laser modification or ablation. The applications of these periodically nano- and micro-patterned surfaces may improve the lubricated or non-lubricated tribological performance of surfaces in conformal and even non-conformal contact through a reduction of wear, a variation of the coefficient of friction, altered load carrying capacity, etc., resulting in energy saving, improved reliability, increased lifetimes as well as durability, leading in turn to extended maintenance intervals/reduced down-time. This can be beneficial in terms of bearings, gears, engines, seals, cutting tools, or other tribological components. Fundamental aspects addressed may involve the investigation of the relevant physical and chemical effects accompanying the laser-generated nano- and microscale topographies, such as alterations of the material structures, the hardness, superficial oxidation, the role of additives contained in lubricants, surface wettability, micro-hydrodynamic effects, etc. For this Special Issue we aim to attract both academic and industrial researchers and would like to provide a bridge between research in the fields of tribology and laser material processing in order to foster the current knowledge and present new ideas for future applications and new technologies.

Schlussbericht zum BMWi/MNPQ-Verbundprojekt: PLASMA-FIT (PLASMA-kompatible Partikel zur gepulsten in-situ Injektion von ex-situ hergestellten Partikeln für add-on Funktionen und zur Identifizierung in BeschichTungen) (2015)
Beck, Uwe ; Baier, Jennifa ; Dähne, L. ; Lerche, K.-H.
Im Fokus steht die Qualitätssicherung mit Blick auf Herstellung, Modifizierung, Handling und Erprobung von PLASMA-kompatiblen Partikeln zur gepulsten in-situ Injektion von ex-situ hergestellten Partikeln für add-on Funktionen in und zur Identifikationsprüfung von BeschichTungen (PLASMA-FIT). Im Kern war zunächst zu prüfen, welche Klassen ex-situ hergestellter Partikel unterschiedlichster Materialien überhaupt bzw. unter welchen Bedingungen PLASMA-fit sind oder unter welchen Randbedingungen PLASMA-fit gemacht werden können. In den dazugehörenden Projektphasen Screening und Adaption stand dabei das komplexe Beanspruchungsszenario bestehend aus Vakuum-, Temperatur- und wenigstens kurzzeitiger Plasmabeständigkeit der ex-situ bereitgestellten Partikel im Fokus. In der Projektphase Applikation sollte dann unter Verwendung einer modifizierten Plasmaquelle (BAM-Patentanmeldung, beabsichtigte Lizenznahme durch Fa. CemeCon, Optionsvertrag) hinsichtlich der Realisierbarkeit, Prüfung und Qualitätssicherung von Plasmadispersionsschichten ein erster Praxistest zur in-situ Injektion von Partikeln in einen laufenden Beschichtungsprozess, zur Realisierung funktioneller Eigenschaften z.B. zur Identifikation oder Authentifizierung von Originalteilen, vorgenommen werden
Bio-based concrete - Materials innovation for sustainable future construction (2019)
Concrete is typically perceived as a grey material that is relatively cheap and easy to use for mass application. The global relevance of concrete is often ignored despite its tremendous environmental, economic, and social impact. Construction materials are a major impact on the climate change, but building is inevitable for social and economic development. Therefore, it is important to develop more sustainable materials to build habitat and infrastructures. A reasonable approach to build more sustainably with concrete is to use agricultural by-products as chemical or fibrous performance enhancers and/or as replacement of cement in the binder.
