Gasoline, also known as petrol, is a prevalent liquid fuel derived from crude oil through refining processes. It is specifically designed for use in spark-ignition internal combustion engines, commonly found in automobiles, motorcycles, and small aircraft. Gasoline is composed primarily of hydrocarbons with additives to enhance engine performance and reduce emissions. It is highly flammable and volatile, making it suitable for combustion within the cylinders of an engine. Moreover, gasolines widespread availability and efficient energy release make it a preferred choice for transportation and power generation.

A gas turbine, also known as a combustion turbine, is a type of internal combustion engine that converts chemical energy from fuel (generally a variety of gases, such as natural gas, process gas, low-Btu coal gas, and others) into mechanical energy through the process of combustion. Gas turbines are commonly used in different applications, including power generation, aviation, and industrial processes. They operate on the principle of continuous combustion, where fuel (gas) and air are continuously mixed and burned to produce a high-speed and high-energy exhaust gas stream.

A membrane is a type of selective barrier used to remove or separate a feed stream as it passes through. Membranes are generally used for gas separation. Gas separation membranes are used to separate and purify specific components from other gases or vapor mixtures. The gas separation membrane technology is widely used in gas processing applications in different industries, such as petrochemical, chemical, and manufacturing.

Gambling involves wagering money or valuables on an event with an uncertain outcome, with the primary intent of winning additional money or goods. It encompasses activities like sports betting, casino games, poker, lottery, and horse racing.

A gaming console is a dedicated computer designed for interactive video games and viewing services. A video game console works like a PC and consists of the same components, such as CPU, GPU, and RAM. Consumers use controllers to play games. A controller is a handheld device with buttons, joysticks, or keyboards.

A fundus camera is a specialized diagnostic device used in ophthalmology to capture detailed images of the retina, optic disc, and posterior segment of the eye. Combining low-power microscopy with a high-resolution camera aids in detecting, diagnosing, and monitoring various eye conditions, such as diabetic retinopathy, glaucoma, and macular degeneration. With advanced features such as wide-field imaging, fluorescein angiography, and true-color imaging, fundus cameras are essential for precise ocular assessments, documentation, and treatment planning in both clinical and research settings.

Functional mushrooms, also known as adaptogenic mushrooms, are a type of fungi that have various health and nutritional benefits. These mushrooms are widely used in traditional medicine systems such as Ayurveda and Traditional Chinese Medicine (TCM) for their purported medicinal properties. Functional mushrooms are widely used for preventing, alleviating, or treating diseases and/or for their nutritional benefits. Also, functional mushrooms are mainly used in the form of powder or as extracts.

Functional foods and beverages are modified food and beverages that claim to enhance the well-being and health of consumers, providing value-added benefits beyond the traditional nutrients contained in normal foods and beverages.

Functional food ingredients are components added to foods that provide health benefits beyond basic nutrition. These ingredients can help protect against chronic diseases, improve overall health, and support proper bodily functions.

Fruit-flavored soft drinks are beverages that primarily feature the taste of various fruits. These drinks can be made with artificial or natural fruit flavors, or a combination of both, and often include added sugars or sweeteners.
