International Association of Advanced Materials (IAAM) has continuously been promoting the not-for-profit Diamond Open Access journal publishing practices since June 2010. Thank you for your support and contribution as a reader, author, reviewer and/or editor of purely not-for-profit Diamond Open Access Journal (DOAJ) and IAAM’s official journal, Advanced Materials Letters. This issue of the journal has also been released on the model of Diamond Open Access (DOA) to aid the organization’s objective of ‘Advancement of materials to sustainable and green world’. In April 2020, the fourth issue of the 11th volume of Advanced Materials Letters was release. This issue has highlighted the ideas and new research that can facilitate the ‘Advancement of materials to sustainable world’ and pandemic situation of COVID-19. The April 2020 issue is published 09 articles includes materials knowledge, new findings, and perspective. The issue takes forward the challenges due to the worldwide pandemic situation of Coronavirus and reviewed the present situation and suggests appropriate measures that can be considered to get rid of public health challenges.
Article 1: Current Scenario Of Coronavirus Pandemic
The perspective article of the present issue highlights the current pandemic situation and worldwide challenges. International Association of Advanced Materials (IAAM) intends to provide a forum for high-tech healthcare. Foreseeing the current crisis, IAAM called a multi-lateral consortium to discuss the possibilities of developing a medical technology to control the spreading of coronavirus with the help of interdisciplinary experts from multiple countries. This innovation is perpetuated to create multi-lateral cooperation in the area of ‘healthcare innovation and technology’. Adaptation of advanced technologies and their logical integration according to contemporary healthcare measures could be a smart strategy for epidemic management activities. This article has overviewed the global situation, efforts, and prospective of coronavirus pandemic.

Article 2: Study On A New Type Of Walking Training System With Human Compatibility
The second article of the issue authored by Yasuhiro Hayakawa and Yuuta Kimata from the National Institute of Technology Nara College, Japan reviews the related research on the developed system enables real-time measurement of changes in foot pressure distribution during walking. The authors have also pointed out that the difference in walking patterns clarification.

Article 3: Vitalized Water
The third article of the issue is authored by authors Pavel Osmera Senior et al., from the Czech Republic. In this article, author explained that there are currently two opposing views on vitalized water. Some authors consider everything around vitalized water as a pseudo-science. On the contrary, there is good and positive insight. In this article the water properties described in detail. Water vortex and magnetic field of permanent magnets change some of the water properties. The article explains the diamagnetism of water.

Article 4: Piezoelectric D15 Shear-Mode Sensor In Parallel And Series Configurations
The fourth article of the issue presented the sensor response experiments of piezoceramic shear same poled d15 patches which are integrated into a composite sandwich beam-like structure and connected in parallel and series configurations.
The article authored by Pelin Berik from the Department of Science, Mathematics and Technology, Medaille College, USA. In this article, results are promising as the proof of using piezoceramic shear same-poled d15 patches to sense the response of beam-like composite structures.

Article 5: A Lowering Friction Treatment For Railway Materials
The next article was focused on the energy efficiency of railway transportation. This article is authored by Frank Otremba et al, from Bundesanstalt Für Materialforschung Und-Prüfung (BAM) and Federal Institute for Materials Research and Testing (BAM), Germany. In this work, a carburizing treatment is proposed to reduce the friction between the rail and the wheel´s flange, involving the selective carburizing of the lateral surface of one of the rail head´s sides. The proposed furnace´s design is supposed to the installed next to the hot-rolling facility and includes the needed equipment to avoid decarbonization of the non-treated rail material.

Article 6: Biomachines For Medical Diagnosis
The sixth article was authored by Francisco Santos Schneider et al., from Sys2diag, CNRS, Biological Complex System Modeling and Engineering for Diagnosis in collaboration with Inria, Saclay, and LRI CNRS, Université Paris Sud, France.
In this research, authors explained that in order to design robust synthetic biological biosensor systems reliable in a clinical context and based on biochemical circuits, they developed an original methodology ensuring biochemical implementation of logical tasks within nonliving artificial cells. This methodology covers in silico design, simulation, microfluidics production and clinical validation on human samples. It ends up in a very simple assay like for instance the new insulin-resistance assay, which is also quick and easy to run out of a laboratory and at low cost.

Article 7: Do The Ni Binding Modes On C12N12 Cluster Influence Its H2 Trapping Capability?
The seventh article of the issue was focused on new promising material for hydrogen storage application, where Nickel (Ni) has been decorated on C12N12 nano-cluster. This article is authored by Gourhari Jana et al, from the Indian Institute of Technology Kharagpur in collaboration with Assam University and Indian Institute Of Technology Bombay, India. This work describes whether Ni, being a 3d transition metal, can influence the aromatic behavior of C12N12 nano-cluster. The hydrogen adsorption capacity of the strongest and the weakest Ni-bonded Ni-C12N12 nano-clusters (XNN and XCN isomers, respectively) has also been investigated.

Article 8: Investigation Of Mechanical, Thermal And Melt Flow Performance Of Polycarbonate Hybrid Composites Containing Mica Flakes And Glass Fiber
In the eighth article, Ibrahim Alhaj et al., from Department Of Chemical Engineering And Applied Chemistry, Atilim University in collaboration with Turkish Standards Institution, and Inovasens Ltd., Izmir Technopark, Turkey is reported the glass fiber (GF) and mica (MC) filled polycarbonate (PC) composites. The materials were fabricated using the extrusion process for potential applications in mainly medical, packaging and transportation fields. In this article, the authors explained that individual inclusions of additives yield higher mechanical and thermal performance than hybrid composites.
