Electric Vehicle Battery Systems Thermal Issues
Electric vehicles battery systems (EVBS) are subject to complex charging/discharging processes that produce various amount of stress and cause significant temperature fluctuations. Due to the variable heat generation regimes, latent heat storage systems that can absorb significant amounts of thermal energy with little temperature variation are an interesting thermal management solution.

Wind Energy Conversion Systems Based on Synchronous Generator
Since 20th century, electricity has been widely available, and a large portion of it is produced using coal and gas. Because of its adaptability and simplicity of delivery, electricity is a premium kind of energy. Global demand is rising because of rising consumer electronics, associated industrial activities, and greater consumer access in emerging nations. The most reliable and progressive renewable energy source is wind power. Utilizing the highest amount of wind power available and operating the wind turbine (WT) at its maximum energy conversion output is essential for the rapid adoption of wind generators in electrical grids. To complete this, a wind energy conversion system (WECS) must track or run at the maximum power point.

Adhesive Joint Design for Hybrid Automotive Wheel
When it comes to lightweight design of automotive wheels, hybrid designs consisting of a carbon composite wheel rim and a metallic, e.g., aluminum alloy, wheel disc offer significant potential. However, the conventionally used bolted joint between the two parts is complex and requires compromises in lightweight design due to the additional mechanical elements. An adhesive joint for a hybrid wheel is developed in order to demonstrate its performance and lightweight potential.

Increasing Growth of Renewable Energy
The growth of renewable energy actively takes part in decarbonizing the fossil-fuel-based energy system. It reduces carbon emissions, carbon footprint, and greenhouse gas emissions and increases clean energy. The usage of renewable resources reduces and solves several problems, such as increasing temperature, carbon footprint, greenhouse gas emissions, and energy waste. Every sector contributes to increasing the above-mentioned factors in the environment. One of the main reasons for this biodegradation and climate change is energy resources. Using renewable energy instead of fossil fuel can solve the problem. This text aims to find open research problems about the application of renewable energy and to initiate new innovative ideas regarding renewable energy. A detailed state of the art includes trends for renewable energy resources, their theoretical evolution, and practical implementations. Methodologies used for decision analysis in renewable energy are discussed in detail. The time frame for this analysis of renewable energy is 2010 to >2022. An extensive literature review finds a huge research scope in applying renewable energy in other research, such as logistics, smart production management, and advanced inventory management. Then, major changes in the profit/cost of that system due to renewable energy can be analyzed. This text proposes some innovative new ideas related cost formulas for renewable energy for the corresponding open problems.

Waste as Cement Replacement in Foamed Concrete
Foamed concrete is a lightweight construction material that has gained popularity due to its excellent thermal and acoustic insulation properties. Foamed concrete production involves using cement as a binding agent, which results in a high carbon footprint. In response to sustainable development goals (SDG), there has been a growing interest in exploring alternative materials that can replace cement to improve energy efficiency, climate change, resource efficiency, and overall improvement of foamed concrete properties.

Effects of Temperature/Water Types on Coronavirus Decay
The analysis of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) gene copy numbers in wastewater samples can provide quantitative information on Coronavirus Disease-19 (COVID-19) cases within a sewer catchment. However, many wastewater-based epidemiology (WBE) studies have neglected virus decay during the wastewater transportation process in sewers while back-calculating COVID-19 prevalence. Among various sewer condition parameters, wastewater temperature and dilution by fresh/saltwater infiltration may result in a significant change to the virus decay, in terms of both infectivity and Ribonucleic Acid (RNA).

Vacuum Switching Devices in Medium-Voltage Networks
The development of power grid infrastructure and increasingly stringent environmental regulations have intensified work, carried out by researchers and electrical equipment manufacturers, to develop innovative gas-insulated, environmentally neutral devices. The emergence of new designs of circuit breakers and disconnectors, in which the resulting electric arc is extinguished in a vacuum environment, requires the development of appropriate techniques for diagnosing the chambers responsible for the dielectric parameters of the device.

Conservation Voltage Reduction in Modern Power Systems
Conservation voltage reduction (CVR) is a potentially effective and efficient technique for inertia synthesis and frequency support in modern grids comprising power electronics (PE)-based components, aiming to improve dynamic stability. In conventional power systems with synchronous generators, CVR utilization strategies aiming to conserve energy are split into two broad categories namely, open-loop and closed-loop techniques. Electromechanical voltage regulating devices, such as on-load tap changers (OLTCs), line drop compensators, and capacitor banks, are used to utilize CVR through open-loop procedures without measuring the voltage as a feedback signal.

Membrane Bioreactor for Removal of Dyes
Access to clean water is crucial for human health and the advancement of society. However, the decline in water quality has become a serious global issue due to human activities. The United Nations introduced 17 Sustainable Development Goals (SDGs) with the aim of creating a sustainable future for all humankind. One of the most significant of these goals is “Clean Water and Sanitation for All”. However, the discharge of various contaminants into aquatic environments impedes progress towards achieving SDG6. Among industrial effluents, the textile and dye industries are considered to be major contributors to wastewater production. Dyestuffs, which are synthetic, complex aromatic compounds, and ionizing agents, are widely used as coloring agents in industries such as paper, textiles, food, dyeing, and cooking. Following the dyeing process, approximately 15% of the used dyes remain in the wastewater stream, making the colored wastewater effluent a major concern. Conventional wastewater treatment plants have difficulty in removing such chemicals, resulting in over 200,000 tons of dyes being discharged each year in the environment. The release of dyes results in water pollution with resistant compounds that are not easily broken down by natural degradation processes. Several methods have been established for treating dyes from water bodies, including physicochemical and biological approaches. Physicochemical methods, such as membrane filtration, adsorption, ion exchange, advanced oxidation processes (AOPs), and coagulation, have limitations in the removal of dyes due to high cost, inefficiency, and the potential for secondary pollution. In contrast, biological treatment methods, such as membrane bioreactors (MBRs), are cost-effective, safe, environmentally friendly, and efficient for removing dyes. Among the various biological treatment methods, MBRs are regarded as one of the most effective methods for treating wastewater. MBRs are a combination of units for biological degradation and physical filtration
