A fuel cell converts chemical energy into electrical energy through an electromechanical reaction. A typical fuel cell consists of two electrodes, the anode and the cathode, which react to generate electricity. While liquid electrolytes carry electrically charged elements from one electrode to another, a catalyst is required to speed up the chemical reaction inside the fuel cell. Methanol, biogas, hydrogen, natural gas, and hydrocarbons are various fuels that can be used in fuel cells. Fuel cells generate less pollution as hydrogen combines with oxygen to form water, a harmless by-product. Reduced pollution is one of the major factors driving the growth of the Fuel Cell market in North America.

E-learning refers to learning facilitated by electronic gadgets such as PCs, notebooks, and tablets. E-learning is backed by ICT that enables 24/7 learning for users from any access point. The e-learning curriculum includes archived and real-time information. There is no single standard e-learning method used in the Education market. Differentiation is primarily on the type of content delivered and the mode of instruction, which could be classroom based, virtual, or in a blended learning environment. Generic e-learning courses are standard courses offered by service providers, educational institutions, and experts. These courses are prepared as per the standard curriculum, which would be largely universal for a given subject or topic. They are available through the payment of fees or can be accessed through subscriptions. Educational institutions adopt these courses to aid in higher education. In the Corporate, Skilled, and Vocational Training sectors, the content is used for providing generic, functional, and processrelated training.

Unconventional gas is a natural resource found trapped in coal beds, shale blocks, and tight sands. These gas resources are different from conventional energy in terms of reservoirs, geographical areas, and accumulations of natural gas. Different techniques are applied to extract unconventional gas depending on the field and type of gas to be extracted. A common method is hydraulic fracturing, where a hole is drilled into the rock and large amounts of water are injected at high pressure along with sand and other chemicals to create cracks in the rock. The cracks, when opened, will free the trapped gas allowing it to flow to the wellhead. The three types of unconventional gases are listed in the exhibit below.

Styrenic block copolymers, commonly known as SBC, belong to the family of thermoplastic elastomers. SBCs are consumed in bulk compared to other thermoplastic elastomers and have properties similar to rubber, though they are processed as thermoplastics. SBC is added in additives and other high-performance polymeric compounds for the formulation of the final end-products. The major end-use markets of SBC include the Footwear industry, the Paving and Roofing industry, the Medical and Personal Care industries, and several others. SBCs possess unique properties such as recyclability, elastic quality, and good flexibility at lower temperatures.

Flexible plastics are a category of plastics that are thin, light, and easily stretchable, and yet retain barrier properties and have tear- and puncture-resistant characteristics. These properties make flexible plastics suitable for making packaging products. They are chemically inert, cheap, and visually appealing, which enhances the brand appeal of the product they are used to pack. Generally they are used to pack non-durable and fast-moving unit loads and have limited bulk industrial use with the exception of FIBCs. The key customers of flexible plastic packaging products are the F&B, Personal Care, and Pharmaceutical and Healthcare sectors.

Floating LNG refers to a system in which a set of operations and processes are performed for the development of offshore-based natural gas reserves. These systems are mainly used for the production, liquefaction, storage, and transfer of LNG from offshore gas reserves to onshore areas. The floating LNG facility produces LNG directly on the offshore floating system, where it undergoes different processes, is stored in vessels or tanks, and is finally transported to the land. The entire value chain of the floating LNG system is shorter than that of the common onshore LNG system. All the equipment, facilities, and other processes in a floating system take place in a single enclosed structure thereby using just one-third of the space required by a normal LNG system. The use of floating LNG systems eliminates the need for long distance pipelines and onshore infrastructure and therefore ultimately reduces the disturbance to the surrounding environment and minimizes the development costs to a large extent.

A baby monitor, also known as a baby alarm, is a device used to transmit sound and videos to a receiver to keep tabs on activities in case parents are not around. A basic baby monitor functions by using a radio transmitter, wherein he sound produced by a baby is transferred to a receiver. The receiver contains an inbuilt speaker that enables listeners to hear the baby from various locations within a certain range.

Tires track their history back to the mid-1800s, at which time they were made of rubber, best known as solid tires. With time and new advances, solid tires were replaced by pneumatic tires, which were first used in automobiles by the Michelin brothers, who went on to become one of the prominent tire vendors in Europe. Over time, the Tire market has witnessed new technology breakthroughs and the entry of many vendors.

A BMS or building automation system is a computer-based control system deployed in large buildings for efficient energy management. It controls and manages building facilities such as lighting, electricity, fire precautions, safety, security, and HVAC. BMS solutions are installed in commercial buildings, IT parks, hotels, restaurants, manufacturing plants, retail outlets, and residential buildings for effective facility management. They enable easy automation and management of buildings for better cost savings and improved performance.
