The global HB LED market is growing at a high rate due to the benefits of HB LEDs. HB LEDs have better luminosity when compared with traditional LEDs. They are preferred over other lights such as incandescent and compact fluorescent lamps (CFL) for their higher drive current levels and energy efficiency. HB LEDs are known as green lighting systems because of their energy-efficient features and low carbon emissions. They consume 75% less energy than other bulbs and have a longer lifespan (60,000 hours) compared with incandescent bulbs (1,500 hours) and CFLs (8,000 hours).

The term biodegradation refers to the process of decomposition by the action of naturally occurring microorganisms over a period. Biodegradable polymers are derived from renewable sources such as potatoes, vegetable oil, rice, pea starch, tapioca, corn starch, sugarcane, wheat, grains, and cellulose from wood. They can also be produced by combining bio-based resources with petroleum-based resources, such as oil and gas. These products are called bio-based products and have over 50% of bio-based components.

A gas engine is a type of internal combustion engine that uses different types of fuel to generate motive power. Natural gas is the most commonly used fuel in a gas engine. After the engine generates enough high temperature and high pressure, force is applied by the engine. This force moves the piston thus creating mechanical energy from chemical energy. The diesel engine is a substitute of a gas engine. Advantages of gas engines over diesel engines are listed below.

A heat exchanger is a mechanical device that transfers thermal energy from one medium to another. The media are generally separated by a partition to avoid contact between each other. They incorporate fins or corrugations to increase the surface area for enhancing the heat exchange process. Heat exchangers are widely used in industrial applications such as refrigeration, air conditioning, sewage treatment, and natural gas processing. The classic internal combustion engine is the best example of a heat exchange. The engine coolant flows in a circular motion through the radiator coils and air flows past these coils to cool the engine.

Gyro cameras are used to capture extreme action sports or activities. Regular cameras are incapable of capturing high-speed actions and are not designed for rugged conditions, including extreme weather. Gyro cameras are compact, lightweight, designed for rugged conditions, and can be worn on the person or are mountable on vehicles. These cameras can capture high-speed actions and high-quality images. Gyro cameras are used to stabilize videos and photos that are shot in motion. A gyro camera consists of a regular camera and a gyro stabilizer, which ensures that the camera's motions are restricted. The gyro stabilizer has three or two motors depending on the number of axes of movements. These motors ensure that the three movements, which are yaw, pitch, and roll, are countered by the motors in order to stabilize the camera.

Halogen-free flame retardant chemicals are added to flammable materials to resist ignition and inhibit or delay combustion. Phosphorus, aluminum, magnesium, melamine, and boron are widely used for manufacturing halogen-free flame retardants. The major application areas of flame retardant chemicals include polyolefins, paints and coatings, epoxy resins, unsaturated polyesters, polyvinyl chloride (PVC), engineering thermoplastics and others.

Gynecology surgical devices are in high demand for conditions including excessive uterine bleeding, ovarian cancer, cervical cancer, and others. Some conditions are treated without any complications, whereas, some of the procedures involve complications. Several advanced devices and technologies are used to perform complex gynecological procedures. Different portable and disposable devices are available in gynecology and fertility centers.

A grinding machine is a type of machine tool, which is used to cut and shape metals and other materials based on the specifications of the product. The machine uses an abrasive wheel as the cutting tool. The rough surface of the abrasive wheel helps in scrapping off the unnecessary material from the workpiece.

Functional powder drink concentrates contain vitamins, herbs, pre- and probiotic live bacteria, yeasts, non-digestible fiber, and various amino acids. These concentrates constitute a segment of non-alcoholic beverages, and are formulated to improve digestion, boost immunity, boost energy and stamina, promote health functions (for example, the health of the heart, bones, and joints), and provide a feeling of satiation. These products are also convenient and can be consumed on-the-go. These two aspects have a vital role in influencing consumers' purchase decisions.

Unconventional oil and gas are trapped in rock formations that have low permeability. Pathways must be created to permit the passage of oil and gas through the rocks and into the well, enabling it to be pumped to the surface. Hydraulic fracturing is commonly employed for creating these pathways. Hydraulic fracturing is a well stimulation method in which a fluid (mainly a mixture of water, sand, and chemicals) is pumped at high pressure to create fractures in the rock, thereby allowing oil and gas to move toward the well from deep reserves.
