In the subject of energy storage, materials engineering is crucial. Engineering nanoscale materials provides unique characteristics that result in high-performance electrodes and electrolytes in a variety of energy storage systems.

As a result, in recent years, considerable efforts have been made to meet the future requirements of electrochemical energy storage utilizing these sophisticated materials. Various multifunctional hybrid nanostructured materials are now being investigated to increase the energy and power density of next-generation storage devices. A growing interest in sequence-specific nucleic acids with selective recognition properties towards low-molecular-weight substrates and macromolecules (aptamers) as functional biopolymers for analysis, medical applications such as imaging, drug delivery, and even therapeutic agents, nanotechnology, material science, and other fields is growing.

Low-intensity black light tubes emitting in the Near-UV were used to produce efficient pesticide photodegradation. Bioenergy storage systems based on hybrid nanostructures that can turn on and off motor activity in real-time. Solar energy has traditionally been utilized for two purposes: power and heat, for example to heat water or air for household and commercial purposes such as heating, drying, and cooling. A concentrated solar power plant, for example, may use solar thermal energy to generate electricity where solar photovoltaic technology uses a semiconductor solar material to transform solar energy into electricity. The third dimension of solar energy-based fuel production is receiving a lot of attention.
