E2W is a term used for electric motorcycles, scooters, and bicycles. They are powered by batteries instead of liquid fuel. E2Ws consist of a DC motor, controller, battery, and charger instead of an ICE, as used in liquid fuel-powered two-wheelers. E2Ws are considered more environment friendly as well as a fuel saving alternative in comparison with liquid fuel-powered two-wheelers, and are a sound choice for short-range travel requirements. E2Ws have become one of the successful mass-produced and adapted alternative-fuel vehicles since the start of motorization.

Pneumatic equipment uses compressed gas (air or any other inert gas) to produce mechanical motion. The equipment is used in volatile environments where hydraulic or electric tools cannotbe used. It is also used in various industries such as Construction, Metallurgy, and Oil and Petrochemical. Pneumatic equipment is safer than electric and hydraulic tools and it is increasingly being adopted by end-users for industrial applications.

Elderly and disabled assistive devices enable the elderly and disabled population to carry out their everyday activities that involve movement, hearing, and reading with ease. The devices are designed for the elderly and disabled population to live more independently with a good quality of life. The devices include both simple and complex products in design. For instance, wheelchairs, crutches, and mobility scooters are among the simplest in design, while reading machines, hearing aids, and transfer lifts are much more complex in design.

Nuclear decommissioning is the process of dismantling a nuclear facility permanently. The nuclear decommissioning process commences once the owner decides to permanently close down the nuclear facility. It involves the removal of used nuclear fuel from the reactor, cleaning, dismantling, and disposing of all the radioactive components. The decommissioning process is completed when all radioactive wastes and components have been completely dismantled or decayed to a level such that the site can be safely reused for other purposes. Depending on different decommissioning strategies, this process can take decades. Globally, many nuclear reactors have been safely decommissioned. Nuclear decommissioning can be carried out in three ways: immediate dismantling, deferred dismantling, and entombment.

FMCG are fast moving consumer goods that are present in retail, supermarket and local retai l shops. These are physical goods that are produced and purchased to satisfy the needs of consumers. Some of its key segments are Food, Beverages, Healthcare and Medical, Cosmetics,Industrial Goods, Household Products, and Other Goods that consumers use in daily life. Food products, beverages, and drugs/medicines need preventive and durable packaging to prevent any spoilage or contamination.

A dental implant refers to the replacement of tooth roots and has a high supportive interface between the jaw (skull) and bone. Dental implants help restore the missing teeth or tooth and consist of three major parts: the implant device itself, the abutment, and the crown or denture. A dental implant is made up of biocompatible metal, titanium, and zirconium that offer durability and strength with their unique properties, and which fuse directly into the bone. Dental implants are used by people who suffer tooth loss. Some of the major reasons for tooth loss are tooth decay, gingivitis, injury, congenital defects, root canal failure, and excessive wear and tear. Osseointegration is a process that helps to lock or joint the implant directly into the jawbone, and it is used to replace teeth of different designs and structure, and it can also replace a singl tooth to a full arc. Dental implants are available in a wide variety and different colors and can also be customized.

An SOFC is a device that generates electricity through an electrochemical process that involves oxidation of electrolytes when placed between two electrodes - anode and cathode. Fuel cells are generally categorized based on the type of electrolyte material used in them; an SOFC uses a solid oxide or ceramic electrolyte. Some of the advantages of an SOFC include low cost, low emissions, long-term stability, high efficiency, and fuel flexibility. Its high fuel flexibility permits the use of cheap, safe, and readily available fuels such as hydrocarbons, natural gas, hydrogen, methanol, and syngas. An SOFC, however, requires a high operating temperature, usually within the range of 932 degrees Fahrenheit to 1,832 degrees Fahrenheit, for the activation of ceramics. This high operating temperature leads to mechanical and chemical compatibility issues and longer start-up times.

Brazing is defined as the process of joining two metals by deploying a filler metal such as a brazing alloy. In the brazing process, the filler metal is heated to slightly above its melting point and allowed to flow through capillary action between the two base metals that need to be joined. This process is normally undertaken by using a controlled atmosphere called a flux. The flux is used to prevent, dissolve, or remove oxides that are formed during the brazing process. Brazing is similar to soldering, except that the melting point of the filler metal used in brazing is above 842 degrees fahrenheit while the melting point of that used in soldering is below 450 degrees centigrade.

Geomembranes are synthetic membrane liners used in geotechnical engineering to contain or control the flow of fluids or vapors. The two common processes used to manufactur geomembranes are calendering and extrusion; the raw materials used are polyethylene bitumen composites, or geotextiles in combination with polymer sprays, colorants, asphalt, or elastomers. HDPE, LDPE, PVC, PP, and EPDM are the most widely used forms. Geomembranes are vital to the Waste Management, Water Management, and Mining industries.

miRNAs are single-stranded, small, non-coding RNA molecules that regulate gene expression at the translation level. They play a vital role in research, diagnostics, and therapeutics to study expression of genes and to control diseases by gene silencing. They interact with mRNA molecules and regulate expression of genes by mRNA cleavage, translational repression, and deadenylation. They are generally 17-27 nucleotides long and regulate post-transcriptional mRNA expression by binding to the 3’ untranslated region of the mRNA sequence, which results in translational suppression and gene silencing. miRNAs are involved in a wide range of biological processes, including apoptosis, cell cycle control, and several developmental processes such as stem cell differentiation, hypoxia, hematopoiesis, neurogenesis, insulin secretion, cardiac and skeletal muscle development, aging, cholesterol metabolism, viral replication, and immune responses. They can be used as therapeutics for the treatment of some severe diseases including cancer and genetic disorders by introducing specific miRNAs into diseased cells to silence the defective gene.
