Poly(Ethylene Terephthalate) Microplastics
The high PET production volume and the waste mismanagement of PET litter make it one of the most polluting plastic material. Its diffusion in marine litter is widely assessed according to public opinion and documented in the literature. The major sources of PET microplastics in the marine environment are bottles and fibers. The role of PET micro/nanoplastics of vector of toxic chemicals, their fate and the negative effects on the environment and human health is still under discussion.

Constituents of a Free Radical UV Curing System
The essential constituents of a UV curing system are a resin, which is an oligomer whose backbone confers the properties to the final polymer; a monomer, which acts as a cross-linking agent and adjusts the viscosity of the mixture to an acceptable level for application; and a photoinitiator, which is responsible for the light absorbance and governs the curing depth and rate.

Conducting Polymers
Conducting polymers are an important class of functional materials that has been widely applied to fabricate electrochemical biosensors, because of their interesting and tunable chemical, electrical, and structural properties. Conducting polymers can also be designed through chemical grafting of functional groups, nanostructured, or associated with other functional materials such as nanoparticles to provide tremendous improvements in sensitivity, selectivity, stability and reproducibility of the biosensor’s response to a variety of bioanalytes. Such biosensors are expected to play a growing and significant role in delivering the diagnostic information and therapy monitoring since they have advantages including their low cost and low detection limit.

Supercapacitor
Supercapacitors are electrical devices for fast storage and release of electric energy utilizing charge accumulation in the electrochemical double layer. In terms of volumetric and gravimetric capacities they exceed conventional dielectric and electrolytic capacitors by several orders of magnitude. However, the low energy density of supercapacitors has seriously limited their wider application in many fields. Increase of energy density highly depends on development of a new generation of advanced electrode materials for supercapacitors.

Pyrolysis of Polystyrene Waste
The manufacturing of polystyrene around the globe has escalated in the past years due to its huge applications in various areas. The perpetual market needs of polystyrene led the polystyrene wastes accretion in the landfill causing environmental deterioration. The soaring need for polystyrene also led to the exhaustion of petroleum, a non-renewable energy source, as polystyrene is a petroleum-derived product.

Polymeric Surfactants
Polymeric surfactants are surfactant molecules that have a polymeric backbone, which can be made up of various repeating units. These surfactants have both hydrophilic and hydrophobic segments, which allows them to interact with both water and oil. Polymeric surfactants are used in a variety of industrial applications, such as in the production of paints, adhesives, and coatings. They can improve the stability and performance of these products by reducing the surface tension and promoting the dispersion of pigments and fillers. In addition, polymeric surfactants are also used in the formulation of personal care products, such as shampoos, conditioners, and body washes. They can help to improve the texture and feel of these products, as well as enhance their cleaning and conditioning properties. One of the key advantages of polymeric surfactants is their ability to form stable micelles in solution. These micelles are aggregates of surfactant molecules that form a spherical structure with the hydrophobic segments on the inside and the hydrophilic segments on the outside. This allows for efficient emulsification of oil and water, which is important in a variety of industrial processes. Polymeric surfactants are a versatile class of surfactants that offer several unique properties and advantages in various applications. They are commonly used as emulsifiers, stabilizers, and thickening agents, and have potential applications in areas such as agriculture, oil and gas, and papermaking. Polymeric surfactants are a diverse class of surfactants that can be classified based on their composition, molecular weight, and degree of polymerization. They offer a range of unique properties and advantages in various applications, including cosmetics, food and beverage products, pharmaceuticals, and agriculture.
