Electronic Textiles
Electronic textiles belong to the broader range of smart (or “intelligent”) textiles. Their “smartness” is enabled by embedded or added electronics and allows the sensing of defined parameters of their environment as well as actuating according to these sensor data. For this purpose, different sensors (e.g., temperature, strain, light sensors) and actuators (e.g., LEDs or mechanical actuators) are embedded and connected with a power supply, a data processor, and internal/external communication.

Ford Maverick (1970)
The Ford Maverick is a compact car manufactured and marketed by Ford for model years 1970–1977 in the United States, originally as a two-door sedan employing a rear-wheel drive platform original to the 1960 Falcon — and subsequently as a four-door sedan on the same platform. The Maverick was also manufactured in Venezuela, Canada, Mexico, and from 1970 to 1979, in Brazil. The name "maverick" was derived from the word for unbranded range animals, and the car's nameplate was stylized to resemble the head of Longhorn cattle.

Graphene-Based Membranes in Oil/Water Separation
Oily wastewaters, oil spills from the petroleum industry, and oil-shipping accidents have caused detrimental effects on aquatic ecosystems. Several methods were proposed by various number of studies to tackle oil spillage cleanups; these methods include absorption, dispersants, solidifiers, and controlled burning. Absorption is one of the most commonly used methods in the separation and recovery of spilled oil from water thanks to its good efficiency, simple operation, and flexibility to combine with other methods. Graphene has a large surface area, with a high chemical and thermal stability. It is an excellent adsorption material and has several applications in the field of oil spill cleanup and water purification processes.

15 Minute City
The 15-minute city is a residential urban concept in which all city residents are able to meet most of their needs within a short walk or bicycle ride from their homes. The concept was popularized by Mayor Anne Hidalgo of Paris, who was in turn inspired by French-Colombian scientist Carlos Moreno. It has been described as a "return to a local way of life. 15-minute cities are built from a series of 15-minute neighborhoods, also known as complete communities or walkable neighborhoods.

Rural Logistic Facilities
Transport has long been considered a concern for rural residents around the world. Rural express logistics, one of the transport topics, is associated with rural residents’ convenience as well as e-commerce development. As key nodes in the network, logistic centers need to be properly located to improve the delivery efficiency. In general, existing studies on rural logistics are mostly conducted qualitatively. Most studies focus on policy suggestions on the development of rural e-commerce, while geographic, economic, and population data are not exploited enough. Although some issues such as route design and rural e-commerce are getting attention, there are still very few studies on site selection of rural logistic centers. Much uncertainty still exists about balancing the coverage rates with the operational cost when evaluating the optimal locations for logistic centers in remote rural areas with low population density. Quantitative methods are urgently needed for solving the logistic center locating problem, especially in areas at the early stages of building a rural logistic network.

Wave Energy in the Mediterranean
The installed power of the several deployed WECs in the Mediterranean Sea varies between 3–2500 kW. Ten project cases of deployed WECs in the basin are presented, with their analysis of the essential features. Five different types of WEC have already been tested under real environmental conditions in Italy, Greece, Israel and Gibraltar, with Italy being the Mediterranean country with the most deployed WECs. The main questions of the relevant studies were the ongoing trends, the examination of WECs in combination with other renewable sources, the utilising of WECs for desalination, and the prospects of wave energy in the Mediterranean islands and ports.

Broadband Power Line
Broadband Power Line (BPL) communications are enlisted to play an important role in the development of new Smart Grid (SG) services and applications, due to the high-performance features that will be demanded in the transformation of the electrical grid model in the next few years. BPL communications are the most immediate and affordable answer to the SG challenge in the distribution grid. While Smart Metering has been instrumental to reaching the outer edge of the grid (i.e., the customer), the capability to deploy broadband communications through the grid is not just a question of the natural evolution of telecommunication technologies but is a requirement for accomplishing the SG evolution. In particular, BPL technologies are a key tool for the control and monitoring of secondary substations. They will also be essential in the distribution grid, in terms of PQ monitoring and distribution generation, especially considering the growth of solar and wind power sources and the progressive introduction of massive EV fleets, with hundreds of vehicles charging and discharging at the same time. In addition, BPL technologies have a great potential towards the diagnosis of the power grid and security assurance. The methods for cable health monitoring are mainly based on the topological parameters of the network, physical properties of the cable, and the measured Quality of Service (QoS) parameters, while other methods include simulations and diagnostics solutions.

Evaluating Geothermal Systems through Life Cycle Assessment
In these days of heightened environmental consciousness, many countries are shifting their focus towards renewable energy sources for both large-scale uses (such as power plants that generate electricity) and smaller-scale applications (e.g., building heating and cooling). Taking into account a holistic method, LCA on the one hand allows to display the whole life cycle of a system from the extraction of raw materials, its creation to the production phase and finally to its disposal. On the other hand, it reveals through multiple environmental impact categories, the hot spots that account for the different stages of the cycle defining the environmental identity of the system and consequently driving policy makers on taking final decisions. Geothermal energy is an extremely viable alternative that, combined with other renewable energy systems, may mitigate the negative effects of the existing energy mix worldwide.

3D Printed Electromagnetic Vibration Harvesters
Energy harvesting is the utilisation of ambient energy in order to power electronics such as wireless sensor nodes (WSN) or wearables without the need of batteries. This allows to operate the node over a much longer time period compared to battery-powered devices along with lower maintenance efforts. Furthermore, the low-maintenance requirements allow to operate these WSNs in environments with limited or no accessibility.

H2S Removal from Gas Mixtures Using Zeolites
Natural gas, biogas, and refinery gas all include H2S, which has adverse effects not only on the environment and human health but also on the equipment and catalysts that are employed in the relevant processes. H2S is removed from the aforementioned gases using a variety of techniques in order to fulfill the necessary sales criteria and for reasons of safety. The adsorption method stands out among various other approaches due to its straightforward operation, high level of efficiency, and low overall cost. This technique makes use of a variety of adsorbents, such as metal-organic frameworks (MOFs), activated carbon, and zeolites. The use of zeolite-based adsorbents is by far the most common of these various types.
