Extensive deposits of up slip and clay formed in the sea at the river’s mouth are called delta. The river water contains colloidal particles of sand and clay, which carries a negative charge. The seawater contains many positive ions such as \({\text{N}}{{\text{a}}^ + },{\text{M}...
The use of chemical-based cosmetic products for various target organs is becoming an essential part of our daily life. Chitosan and its derivatives can be labeled as natural polymers with antimicrobial and anti-inflammatory properties. The application of chitosan and its soluble derivatives in various...
Which class of polyester to choose? Polyethylene terephthalate (PET) and polybutylene terephthalate (PBT) both belong to the polyester family. The use of alcohol resulting in an ester group makes these polymers distinctive. In chemical composition, PBT differs only slightly from PET. PBT has a hi...
Smart textiles represent a groundbreaking intersection of fashion and technology, offering endless possibilities for innovation in daily wear. From enhancing health monitoring and athletic performance to redefining style and safety, smart textiles are poised to transform the way we interact with clothing....
Ceiling and roof materials are also manufactured in such a way that they are heat resistant and provide cooling to the building. The pipings and switches are all made of polymers and are heat as well as shock resistant. Hence, chemistry made it possible to make use of all such products fo...
Longevity:Polyurethane products typically have a long service life, reducing the need for frequent replacements and maintenance. Cost-Effective:While the initial setup costs for molding tools and equipment may be relatively high, the long-term cost-effectiveness of polyurethane parts, due to their du...
