Preface

Abstract

The 4th Edition of the International Altamira Materials and Devices Encounter (EMDA 4) was successfully held in hybrid format, on November 16th and 17th, 2023 with 196 participants on-site at CICATA Altamira, and ca. 180 participants online. The Scientific Program included 13 invited conferences from around the globe, with researchers from Malaysia, India, Azerbaijan, Romania, United Kingdom, Morocco, USA, Honduras, Mexico, Colombia giving their talks in four sessions (Semiconductors, Modelling, Materials and Engineering and Physical Sciences).Six Workshops were imparted: Elemental Analysis by X-ray Fluorescence, Production of Biobatteries from Plants, Creation of Metamaterials by 3D Printing, Introduction to AI for Materials Science, Electrochemical Methods of Analysis, ANSYS Mechanic Introductory Training. Graduate and undergraduate students benefited from these Workshops, which were also transmitted by YouTube live as well as the rest of the activities of the Conference.https://youtube.com/playlist?list=PL9d20U28c14xN3a1uvGW8-Tbrulu8-HOD&si=-X2PIPFe5gMoh32XA hybrid poster session with 46 posters showing the groundbreaking results of researchers and students was done. The submissions provided the public with a broad view of physics, semiconductors, materials, batteries, engineering applications, mathematical and computational science methods, novel concepts, ideas, and tools. The best posters were judged by a multidisciplinary jury, in two categories: Materials and Devices. The list of winners is depicted in this book.There were 43 conference paper submissions, and after a strict, double-blinded peer review process, 23 papers were selected by the Editor to be published in this volume. A total of 11 reviewers participated in this conference, who provided their professional and objective feedback to the authors to ensure the quality of the manuscripts according to the IOP Editorial’s Guidelines. The accepted papers are grouped into three general topics, i.e. Engineering Applications, Batteries/Supercapacitors and Semiconductors.The papers entitled “nS1-xSex alloy deposition by RF magnetron co-sputtering for potential photoelectrochemical applications”, “Wide-angle microwave attenuation response of a multilevel metastructure based on rGO/Fe3O4/PPy: an in-silicon study”, “Wastewater treatment from graphene oxide synthesis process”, “Physicochemical characterization of urban dust in Southern Tamaulipas using X-ray fluorescence”, “Delignification and characterization of Tule (Typha Dominguensis) for its potential use in the production of green concrete”, won the best materials poster and the paper entitled “Open Source electronic system with OLED screen monitoring of Plant Based Batteries”, “One-bit register based on 180nm CMOS technology”, “Optoelectronic system for measuring sugar content in citrus fruit” won the best devices poster after being reviewed by the session’s jury at the conference.A special acknowledgement is given to Instituto Politecnico Nacional through its Secretaria de Investigacion y Posgrado, from which financial support was possible to waive the fees for this event including the fees for paper publication, which was of capital importance because the highest participation was from graduate and undergraduate students.The kind sponsorship of SCM, SATELSA, and Soporte Analitico Especializado for the Conference banners and specific logistic needs, is kindly granted.Acknowledgements are also given to the Conference Staff, composed of CICATA Altamira and UV students who were the success factor of the Conference.The Organizers also grant the support from CICATA Altamira for the use of their facilities and the all the event logistics, as well as to the effort of the Scientific Program and Technical Committees, who did a great job preparing the event, contacting the Lecturers, confectioning the Program, reviewing the posters and the papers and making valuable suggestions for the authors to improve their work. We also would like to express our gratitude to the external reviewers, who kept the quality of the submitted papers and qualified the presented posters.Finally, on behalf of the Organizing Committees, we would like to express our sincere gratitude to all participants and speakers who contribute to make this event a great success.Looking forward to seeing you in 2025!Organizing Committee of EMDA 4th 2023List of Organizing Comittee, Conference Chair, Program Chair, Program Co-chairs, Steering Committee, Support Committee/Conference Staff and Organizations are available in this pdf.
