Thermophotovoltaic Cell
Generally, waste heat is redundantly released into the surrounding by anthropogenic activities without strategized planning. Consequently, urban heat islands and global warming chronically increases over time. Thermophotovoltaic (TPV) systems can be potentially deployed to harvest waste heat and recuperate energy to tackle this global issue with supplementary generation of electrical energy.

Model Predictive Control for Microgrid
In recent times, microgrids (MG) have emerged as solution approach to establishing resilient power systems. However, the integration of renewable energy resources (RERs) comes with a high degree of uncertainties due to heavy dependency on weather conditions. Hence, improper modeling of these uncertainties can have adverse effects on the performance of the microgrid operations. Due to this effect, more advanced algorithms need to be explored to create stability in MGs’. The model predictive control (MPC) technique has gained sound recognition due to its flexibility in executing controls and speed of processors.

Reconfigurability with Metamaterials
Metamaterials exhibit properties in terms of subwavelength operation or phase manipulation, among others, that can be used in a variety of applications in 5G communication systems. The future and current 5G devices demand high efficiency, high data rate, computational capabilities, cost-effectiveness, compact size, and low power consumption. This variation and advancement are possible when the antenna design is revised to operate over wideband, high gain, and multiband and has characteristics of compact size, reconfiguration, absorption, and simple ease of fabrication. The materials loaded with antennas or, in the same cases, without antennas, offer the aforementioned characteristics to bring advancement in order to facilitate users.

Brain Stroke Monitoring
Stroke is a medical disease that affects millions of people worldwide per year, which leads to permanent disabilities or even death. It occurs when the regular flow of rich-oxygen blood through a brain vessel is interrupted due to a clot or a burst of it, triggering the death of brain cells and requiring prompt diagnosis and intervention after its onset to improve the prognosis significantly. The two main types of stroke are hemorrhagic and ischemic ones.

Cybersecurity in Microgrids
The demand for clean and sustainable energy sources is increasing at a rapid pace, and microgrids (MGs) have emerged as a promising solution for achieving energy resilience, efficiency, and security. As a general definition, a microgrid is a localized power system that integrates renewable energy resources, energy storage systems, and loads to operate autonomously or in parallel with the main grid. As MGs continue to grow in popularity as a means of providing reliable and sustainable energy to communities and businesses, the issue of cybersecurity becomes increasingly important. With the use of digital technology and communication systems, MGs are vulnerable to cyberattacks that can compromise their operation and even cause physical damage.

Electrode Materials for Supercapacitors in Hybrid Electric Vehicles
For hybrid electric vehicles, supercapacitors are an attractive technology which, when used in conjunction with the batteries as a hybrid system, could solve the shortcomings of the battery. Supercapacitors would allow hybrid electric vehicles to achieve high efficiency and better power control. Supercapacitors possess very good power density. Besides this, their charge-discharge cycling stability and comparatively reasonable cost make them an incredible energy-storing device. The manufacturing strategy and the major parts like electrodes, current collector, binder, separator, and electrolyte define the performance of a supercapacitor. Among these, electrode materials play an important role when it comes to the performance of supercapacitors. They resolve the charge storage in the device and thus decide the capacitance.

Energy Trading Markets in Smart Grids and Microgrids
Smart cities are aimed at connecting urban infrastructures to enhance the efficiency of their operation and services while taking sustainability goals into consideration. As a result of the intermittency associated with renewable generation, smart city systems such as smart grids and microgrids may not be able to ensure the security of supply. This can be mitigated by allowing these systems to trade surplus energy with other neighboring systems through local energy markets based on peer-to-peer schemes. Such an approach can play an important role on achieving a state of sustainability due to the positive impacts at the economic, social, and environmental level. Moreover, the implementation of local markets for peer-to-peer energy trading has the potential to provide numerous benefits to both participants and utilities, being a promising solution to reduce the reliability problems of microgrids and solve various energy security concerns in remote locations.

Artificial Neural Networks in Water Supply Systems Development
A water supply system is considered an essential service to the population as it is about providing an essential good for life. This system typically consists of several sensors, transducers, pumps, etc., and some of these elements have high costs and/or complex installation. The indirect measurement of a quantity can be used to obtain a desired variable, dispensing with the use of a specific sensor in the plant. Among the contributions of this technique is the design of the pressure controller using the adaptive control, as well as the use of an artificial neural network for the construction of nonlinear models using inherent system parameters such as pressure, engine rotation frequency and control valve angle, with the purpose of estimating the flow.

Wide Band Gap Devices
A decisive property that regulates semiconductor’s electrical and optical properties is the band gap, which is an important physical parameter for designating a wide band gap (WBG) semiconductor, and is defined as the energy needed for electrons to transition to the conduction band from the valence band. The magnetic property of the semiconducting materials also plays an important role for choosing of power devices in terms of energy efficiency with hysteresis and eddy current losses. The WBG semiconductor materials exhibit larger band gaps (2–4 eV) than their silicon (1–1.5 eV) counterparts and offer greater power efficiency, lower overall cost, smaller size, lighter weight, and lower energy consumption. WBG-based components in semiconductor devices permit its operation at high temperatures, which can be problematic when using conventional silicon semiconductors with smaller band gaps. The wider the bandgap, the higher the temperature at which the semiconductor power devices can function.

IEEE P2668 Evaluation for Smart Battery Management Systems
In smart cities and smart industry, a Battery Management System (BMS) focuses on the intelligent supervision of the status (e.g., state of charge, temperature) of batteries (e.g., lithium battery, lead battery). Internet of Things (IoT) integration enhances the system’s intelligence and convenience, making it a Smart BMS (SBMS). However, this also raises concerns regarding evaluating the SBMS in the wireless context in which these systems are installed. Considering the battery application, in particular, the SBMS will depend on several wireless communication characteristics, such as mobility, latency, fading, etc., necessitating a tailored evaluation strategy.  An IEEE P2668-Compatible SBMS Evaluation Strategy (SBMS-ES) was proposed to overcome this issue. The SBMS-ES is based on the IEEE P2668 worldwide standard, which aims to assess IoT solutions’ maturity.
