The history of phytosterols dates back to the 1950s when the first known pharmaceutical preparation of phytosterols, Cytellin, was introduced in the US market. After their introduction, the adoption of phytosterols started in the 1990s. Phytosterols are widely available in a number of natural sources such as fruits, vegetables, and nuts. To complement these natural sources, phytosterols are being increasingly incorporated into the human diet through fortified functional foods and dietary supplements. Furthermore, phytosterols are also being used in the manufacture of face creams and lipsticks. Phytosterols are known to block the cholesterol absorption in the small intestine and thereby aid in the reduction of LDL cholesterol or bad cholesterol. There is also substantial evidence, as suggested by the Food and Agricultural Organization of the United Nations (FAO), the US Food and Drug Administration (FDA), and the European Food Safety Authority (EFSA) to justify the same. Phytosterols are also known to help in the prevention of cardiovascular diseases and cancer. Various health regulatory bodies prescribe different dosage rates of phytosterols, but a minimum intake of two grams of phytosterols daily is recommended in order to experience the health benefits offered by these compounds.

Nitrogen is an essential plant nutrient. Although the chemical is abundant in the earth's atmosphere, some plants are incapable of converting it into a usable form. Hence, nitrogenous fertilizers are used to help enhance plant growth rates, and colors. The nitrogen in fertilizers stimulates the chloroplasts in the cells of plants, thereby improving the rate of photosynthesis and ensuring consistent crop quality and yield. These fertilizers are available as dry pellets and in liquid form.

The digital era has transformed the way organizations function, disrupting a significant number of business models, processes, technologies, and jobs. As digital data is exploding at a very rapid rate, companies are increasingly pressurized to focus on extracting value from data and implement strategies to make better business decisions. Engineering analytics technology is likely to play a significant role in transforming legacy industrial processes and automated industrial processes. Industries such as manufacturing, healthcare, automotive, transportation, energy, and utilities are some of the industries to embrace the changes. The inevitable need to do everything to reduce costs, increase productivity, enhance efficiency, and grow with the industrial evolution has stimulated the uptake of engineering analytics products and solutions. Deriving actionable intelligence from raw data collected from various internal and external sources is increasingly becoming a strategic priority in industry leadership teams. Engineering analytics solutions help enable this strategy. Engineering analytics services aid in the planning and deployment phases of adopting engineering analytics solutions. Sensor data thus is increasingly gaining huge focus and Technavio expects a high level of investment in this space. Engineering analytics services are predominantly addressable by IT service providers and are associated with the deployment of engineering analytics products. Industrial companies are investing heavily in engineering analytics services for their consulting, system integration, and custom development needs. Technavio expects increased spending on engineering analytics services from OEMs of industrial, energy and utility, and other industries (including transportation, aerospace, and healthcare).

Aircraft interior lighting systems ensure the safety and efficiency of an aircraft's operations and are therefore a key element of an aircraft. These lighting systems have advanced with innovation to provide more effective and efficient operations for the aircraft. They also help in reducing fuel and power consumption. These interior lighting systems are used in the aircraft cabin, the cargo area, and the cockpit. They include ceiling and side wall lighting, reading lighting, and mood lighting that give passengers and crew members better visibility inside the aircraft and enrich their experience.

TIM are used to support heat sinks in removing heat from heat sources in various types of equipment. They are used in the form of secondary thermally conductive materials to replace the thermally insulating air between two surfaces. Besides helping in the efficient transfer of heat, TIM also act as adhesives and strengthen the mechanical link between surfaces. Polymer-based TIM are the most commonly used TIM and owing to their superior conductive and adhesive properties, find extensive usage for thermal management applications in various industries, including computer, electrical and electronics, telecom, and automotive.

A display driver is an integrated circuit, which acts as an interface between a microprocessor and an LCD to control the display system in mobile phones, desktops, and other devices. The display driver IC receives image data and delivers a current to activate the pixels on the display, which contains liquid crystal. When the liquid crystals receive the voltage, they bend, changing the intensity of the light and combining with the color filter on the glass substrate to produce the whole image on the display panel. Display driver ICs form a significant component of display devices.

A printer is a device that inputs text or graphics from computers and prints that on paper of varying sizes. Printers are of two main types: impact and non-impact. Impact printers produce a print image by pressing the print ribbon onto the paper using pins. Non-impact printers do not strike the paper to print an image, and are therefore quieter than impact printers. An example of an impact printer is dot-matrix, and inkjet and laser are examples of non-impact printers. Inkjet printers form an image by dropping tiny droplets of ink on the paper through small nozzles. Laser printers use cylindrical drums that roll electrically charged toner onto the paper.

Aerosol propellants consist of two components: the aerosol and the propellant. Aerosols are a mixture of liquid or solid particles suspended in air or gas, while propellants are chemicals used to generate pressure and push the content out of the aerosol container. Aerosol propellants are convenient for dispensing a wide variety of products, are easy to use, and provide a targeted stream of product that ensures reduction of wastage. Based on product type, aerosol propellants are classified as hydrocarbons, nitrous oxide and carbon dioxide, DME, CFC, and others. Aerosol propellants are used widely in various applications such as personal care, household, pharmaceutical, paints and coatings, industrial, and other related applications.
