The multifunctional power bank is engineered to efficiently charge mobile phones and various electronic devices, featuring dual charging capability that allows it to recharge its battery using both solar energy and grid electricity, thereby enhancing its utility in diverse environments. It eliminates the need for Universal Serial Bus (USB) connections for charging devices, enabling multiple users to charge their mobile phones simultaneously, while also providing the option for a single user to charge their device via USB if preferred. Additionally, the power bank includes built-in data storage and an LED flashlight, further adding to its convenience and functionality.

A secondary loop refrigeration system (SLRS) is an energy-efficient cooling technology where the primary refrigerant is confined to a central unit, while a secondary fluid circulates through the cooling loop to transport heat. This setup reduces the amount of refrigerant used and minimizes direct emissions, making it environmentally friendly.

When nanofluids—fluids enhanced with nanoparticles like metals or oxides—are used as the secondary fluid, the heat transfer efficiency is significantly improved. Nanoparticles enhance the thermal conductivity of the fluid, leading to faster and more efficient cooling, reduced energy consumption, and potentially smaller system sizes. This combination of SLRS and nanofluids presents a promising solution for sustainable and high-performance cooling in various applications, including refrigeration and HVAC systems.

The performance of thermoelectric coolers (TECs) can be significantly improved by integrating phase change materials (PCMs). TECs operate by transferring heat from one side of the device to the other, but they can be limited by temperature fluctuations, reducing efficiency.

PCMs, with their ability to absorb and release large amounts of latent heat during phase transitions (e.g., from solid to liquid), act as thermal buffers. When integrated with TECs, PCMs store excess heat during peak loads and release it gradually as the cooling demand decreases. This stabilizes the temperature around the thermoelectric module, enhances heat dissipation, reduces the cycling of the TEC, and improves its overall cooling performance and energy efficiency. This combination is particularly beneficial in applications requiring consistent cooling, such as electronics cooling and medical devices.

Concrete with low thermal conductivity, often referred to as thermal insulating concrete, is designed to reduce heat transfer, making it ideal for energy-efficient buildings. By incorporating lightweight aggregates or air-entraining agents, this type of concrete can reduce its thermal conductivity while still maintaining structural integrity. This helps in minimizing heat loss in colder climates and heat gain in warmer climates, thereby improving overall energy efficiency.

Porous concrete made from recycled or waste solar PV panels is an innovative approach to sustainable construction. Waste PV panels, often composed of glass, silicon, and other materials, can be crushed and used as aggregates in concrete mixtures. This not only diverts waste from landfills but also creates a more porous structure in the concrete. The porous nature of this concrete allows for better water permeability, making it useful for applications like pavements and drainage systems. Additionally, it may contribute to environmental sustainability by reducing the carbon footprint of both concrete production and PV panel disposal.

Liquid immersion cooling using lattice-structured fins enhances heat dissipation in electronics and batteries by submerging them in a dielectric liquid. The lattice fins, with their porous and optimized geometry, increase surface area and promote efficient fluid flow and heat transfer. This technique improves cooling, prevents overheating, and extends the lifespan of high-power systems, making it ideal for applications like data centers and electric vehicles.
