Smart helmets are an efficient safety tool that improves situational awareness and traffic safety. Smart helmets are becoming increasingly popular among consumers, primarily because of features such as integrated communication systems, real-time navigation, and increased safety. The helmet is developed as a smart for detecting accidents in motorcycles and also sends the geographical location to the concerned authorities. The device is interconnected with IoT, which is embedded with sensors, software, and network connectivity. The smart helmet has dual-mode Bluetooth technology, an integrated video camera, turn signal indicators and brake functions, speakers, and microphones to connect with mobile phones.

Combined heat and power, also known as cogeneration, is an efficient process that generates electricity and captures and utilizes the waste heat produced simultaneously. It involves using a single fuel source, such as natural gas or biomass, to generate electricity through a generator or turbine. The waste heat generated during this process is recovered and utilized for heating, cooling, or other thermal energy applications. Combined heat and power systems offer higher energy efficiency, typically exceeding 80%, compared to separate production of electricity and heat. They provide cost savings, reduce fuel consumption, and contribute to environmental sustainability by maximizing the use of energy resources. Combined heat and power find applications in various sectors, including industrial, commercial, and residential settings.

Coalescing agents are chemical additives that are added to paint and coating formulas to help scattered particles merge or coalesce and improve the creation of films. They facilitate better paint application, drying, and the formation of a cohesive, smooth layer by lowering the minimum film-forming temperature. Coalescing agents are essential for preserving paint performance and quality while lowering emissions of volatile organic compounds (VOCs).

Coal gasification is a thermochemical process in which coal is subject to heat and pressure in a gasifier to break it down into its chemical constituents. The resulting product, known as syngas, primarily comprises carbon monoxide and hydrogen and, occasionally, other gaseous compounds. Syngas can be used for electricity generation, as a fuel in energy-efficient fuel cell technology, and even as a chemical building block in industrial applications. Moreover, hydrogen can be extracted for use as fuel in a hydrogen economy. Also, syngas can be used to produce transportation fuels that can be a substitute for gasoline in vehicles.

Cloud storage services refer to a model for data storage on the Internet through cloud service providers. The service providers manage and operate data storage as a service. The services are delivered to enterprises on demand with a flexible payment structure, which eliminates the need to buy and manage their own data storage infrastructure. Service providers also offer backup and recovery and data collaboration services for enterprises. Cloud storage services offer many advantages to enterprises, such as fast deployment, scalability, agility, reduced CAPEX, mobility enforcement, and uninterrupted business continuity.

Carbon tetrachloride is a sweet-smelling colorless liquid also known as tetra chloromethane and carbon tet. Carbon tetrachloride molecules consist of one carbon atom that is surrounded by four chloride atoms. Carbon tetrachloride is a non-polar compound, which is a very good solvent that readily dissolves other non-polar compounds like oil, fat, and iodine. Carbon tetrachloride is extensively used as a fire extinguisher, refrigerant, and as a cleaning agent.
