Bioplastics are plastics that have been made from renewable biomass sources or food crops such as vegetable fat, corn starch, vegetable oil, pea starch, and microbiota. The different types of bioplastics available include polymers that are directly extracted from biomass and processed, polymers that are made from bio-based precursors such as PLA, and polymers that are made by bacteria such as PHA and PHB. Bioplastics are different from conventional plastics, and they can be used to produce various products such as utensils, bags, furniture, carpets, films, bottles, cups, and packaging materials. They are less harmful than other plastics, which are generally made from fossil fuels (such as petroleum), and they produce lower amounts of GHGs than other plastics. Consequently, the use of bioplastics helps in the reduction of carbon emissions, which is not possible with fossil fuel-based plastics. Bioplastics are widely used in the Packaging sector as they are eco-friendly in nature and reduce the risk of food contamination.

Halogen lamps are the most popular and widely used form of automotive lighting. These lamps are made of non-metal chemicals that are highly reactive and poisonous. They have a tungsten filament and a glass filament that is filled with halogen gas. Halogen lamps are primarily used in automobiles as the light emitted by these lamps is extremely bright, which improves the visibility for automobile drivers. They also have a much longer life than regular lamps, are cost-effective, and are easily available in the market. Halogen lamps have been adopted across all geographies, and hence automobile manufacturers have been using halogen lamps in automobiles for more than a decade.

The objective of this project, was therefore, to develop a prototype sensor technology, membrane-extraction (ME)-IMS, that could be used in situ or ex situ, to characterize the extent of groundwater plumes, conduct compliance monitoring around waste facilities or at the leading edge of a plume, and monitor remedial actions. The IMS instrument could also be used to monitor CHC in the vapor phase.

Crystal oscillators are electronic circuits that generate electrical signals with precise frequencies. To generate these electrical signals, they make use of a vibrating crystal made of piezoelectric material. The frequency generated is used to keep constant track of time and provide a timely clock signal for electronic integrated circuits. This frequency is also used to stabilize frequencies for radio transmitters and receivers. Crystal oscillators find their application in a large number of devices such as cell phones (smartphones and feature phones), tablet computers, wristwatches,clocks, FM radios, medical electronic equipment, automotive systems (tyre pressure monitoring systems and anti-braking systems), and personal computers.

DBT is a 3D imaging technique used in detecting breast cancer. The DBT device captures images of thin slices of a stationary compressed breast at multiple angles during a short scan. After the scan, the images are reconstructed using algorithms into a series of thin high-resolution slices whose planes are parallel to the breast support plates. Tomosynthesis differs from computed tomography because the range of angles used is less than 360?. DBT provides several advantages and enhances the quality of the medical services available to patients. It minimizes recall rates, requires less compression of the breast, reduces tissue overlap in images, and provides efficient diagnosis of small tumors and skin lesions.

Chromatography systems are used for the purification of biochemical, environmental, and other chemical entities using the principle of separation chemistry. The major entities which are regularly separated are metabolites, proteins, carbohydrates, and salts. Chromatography systems are routinely used in pharmaceutical companies and academic institutes for commercial production of biopharmaceuticals and analysis of various molecules. Owing to the increased demand for biopharmaceuticals, the chromatography systems are automated and integrated as a unit in small to large laboratories and large commercial companies. As a result, chromatography systems have become an important accessory tool for various research and commercial purposes.

ACC is a driver assistance system that is incorporated into a vehicle to help the driver maintain constant speed and keep safe distance from other vehicles. ACC automatically manages vehicle speed if there is any obstruction in front of the car and warns the driver in an emergency. The purpose of installing an ACC system is to enhance safety and efficiency. It is designed to help prevent accidents caused by driver error such as poor reaction time and drowsiness. This system is highly efficient in warning a driver whenever required and in providing improved comfort during long drives.
