The consumption of rechargeable batteries is growing globally, covering all major sectors, including consumer electronics, energy, automotive, and telecom. The efficiency of the batteries (the maximum output power with respect to size and weight) has improved due to the advances in technologies. This growth in the global rechargeable battery market has prompted companies to become knowledgeable about the thermal management of battery systems, such as solutions for overheating and cold weather conditions, to improve battery life and performance.

An electric motor is a machine that converts electrical energy into mechanical energy by the interaction of magnetic field with the current. The motor mainly consists of two parts: a rotor and a stator. The motors can be categorized into direct current (DC) motor and alternating current (AC) motor based on the type of electricity used by the motor. Furthermore, AC motors are classified into synchronous or asynchronous motors, and DC motors are classified into brushed and brushless motors.

Global agricultural production grows in tandem with the demand for agricultural products. However, production worldwide has decelerated in the recent years as the demand for agricultural products has reduced because of global environmental changes and slow population growth in developed countries. This is expected to decrease the demand for food, and in turn, lead to a further decline in agricultural production. This is bound to significantly hamper the market growth during the forecast period.

Attack helicopters or gunships are designed to carry heavy armaments such as antitank guided missiles (ATGMs) like Hellfire, auto canons, unguided rockets, heavy machine guns, and air-to-air missiles. The air-to-air missiles carried by them are mostly deployed for self-defense purposes. In addition, attack helicopters attack enemy tanks, flanks, and rear, which provides strategic support and assistance to the ground forces to maneuver and engage with hostile forces. In recent years, the threats imposed on civilian life have increased rapidly, particularly due to the rise in terrorism and crossborder insurgent activities. Therefore, development and procurement of attack helicopters have been increased in recent years to have a highly efficient and effective aerial attack force.

Artificial organs are human-made bioartificial devices, which are implanted or integrated into individuals to replace or support natural organs. These include artificial heart, kidney, pancreas, and cochlear implants. Biocompatible materials such as polymers (polyurethane, polysulfone, and porous polypropylene), biologics, ceramics, and metals are used to develop artificial organs. These organs are incorporated with different technologies like sensors, biomaterials, and innovative delivery systems. Artificial organs perform the function of the natural organ and help the patient to live a quality life. In few cases, artificial organs are capable of eliminating the need for organ transplantation altogether.

Aroma chemicals, also called odorants or fragrances, are natural or synthetic compounds that are characterized by their pleasant smell. These compounds are usually obtained from essential oils and the aromatic compounds. They have a molecular weight less than 300 Da and are extremely volatile and tend to vaporize. Aroma chemicals are used in the products to provide a specific fragrance or to mask the smell of the other product ingredients. They are added to different products such as food and beverages, cosmetics and toiletries, perfumes, fragrance oils, soaps and detergents, and other household products to give them a distinctive odor or smell. These are also used in odorless gases such as natural gas, hydrogen, and propane so to ease their detection in cases of leakage.
