Special Issue Information

Dear Colleagues,

Global warming is a major cause of concern. Consumption of fossil fuels has to be reduced in order to diminish CO2 emissions by 40% by the year 2030 as per the Paris Agreement. Therefore, alternative sources, using solar, wind, water, biofuels, etc., are constantly being explored to meet the global demands for renewable and sustainable energy. Solar cells are used to convert light into electricity using photovoltaic materials. Recently developed materials like two-dimensional MXenes are promised to become supercapacitors that store energy in their layered structures. Yttria-stabilized zirconia solid oxide fuel cells have been demonstrated to run commercial vehicles based on hydrogen fuels. The developers of the Li-ion battery, which laid the foundation for wireless electronics such as mobile phones and laptops, won the 2019 Nobel Prize in Chemistry. Nuclear power is another clean and sustainable source of energy. Traditionally, nuclear fission reactors have been considered dangerous to human civilization due to severe radioactive emission of high-atomic-weight solid oxide nuclear fuels, but with the advent of newer materials and technologies, it will be possible to build a sun on earth; i.e., if hydrogen atoms can be fused into helium (the reaction that happens in the Sun), it will create an enormous amount of nuclear fusion energy, enough to meet world demand. These are merely a few examples of material solutions applied to meeting world energy demand. Newer materials to meet the energy requirement for a sustainable future are continuously being searched for and developed. This Special Issue aims to address some of them.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This paper presents the comprehensive analysis of the sub-microwave, radio frequency band resonant metastructures’ electromagnetic properties with a particular emphasis on the possibility of their application in energy harvesting systems. Selected structures based on representative topologies of metamaterials have been implemented in the simulation environment. The models have been analyzed and their substitute average electromagnetic parameters (absorption, reflection, transmission and homogenized permeability coefficients) have been determined. On the basis of simulation research, prototypes of electromagnetic field two-dimensional absorbers have been manufactured and verified experimentally in the proposed test system. The absorber has been implemented as a component of the low-cost energy harvesting system with a high-frequency rectifier and a voltage multiplier, obtaining usable DC energy from the electromagnetic field in certain frequency bands. The energy efficiency of the system has been determined and the potential application in energy harvesting technology has been assessed. Full article

Nowadays, rechargeable batteries utilizing an S cathode together with an Mg anode are under substantial interest and development. The review is made from the point of view of materials engaged during the development of the Mg–S batteries, their sulfur cathodes, magnesium anodes, electrolyte systems, current collectors, and separators. Simultaneously, various hazards related to the use of such materials are discussed. It was found that the most numerous groups of hazards are posed by the material groups of cathodes and electrolytes. Such hazards vary widely in type and degree of danger and are related to human bodies, aquatic life, flammability of materials, or the release of flammable or toxic gases by the latter. Full article
