Ultraviolet (UV) radiation from sunlight and artificial sources can cause significant degradation in materials, affecting their appearance, performance, and lifespan. To counter this, UV absorbers are widely used as protective additives across industries. A UV absorber is a compound that absorbs harmful UV radiation and converts it into harmless thermal energy, thereby preventing the breakdown of polymers, coatings, and other materials. Unlike stabilizers that act after degradation has started, UV absorbers provide proactive protection by filtering UV light before it can damage a material. This makes them an indispensable component in plastics, coatings, adhesives, and personal care products where long-term durability and stability are essential.

Mechanism of Action and Types of UV Absorbers

UV absorbers work by intercepting UV light in the 290–400 nm wavelength range, which is particularly damaging to polymers and organic compounds. These additives capture high-energy photons and dissipate the energy safely as heat without altering the…

Industrial salts are among the most widely utilized raw materials across various sectors, playing a fundamental role in industries ranging from chemicals and pharmaceuticals to water treatment and food processing. Composed primarily of sodium chloride (NaCl), industrial salts are sourced through natural deposits, solar evaporation of seawater, and mining of rock salt. Unlike table salt, which undergoes extensive purification and is consumed in small quantities, industrial salts are used in massive volumes for processes that directly support industrial production and infrastructure development. Their versatility, cost-effectiveness, and wide availability make them a critical commodity in the global supply chain.

Production and Types of Industrial Salts

The production of industrial salts largely depends on geographic and climatic conditions. The two major methods include solar evaporation and mining. Solar evaporation, common in coastal regions and areas with hot, arid climates, involves collecting seawater in shallow ponds and allowing the sun and wind to…

Carbofuran is a broad-spectrum carbamate pesticide widely recognized for its effectiveness in controlling insects, nematodes, and other agricultural pests. Known chemically as 2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate, carbofuran functions as a systemic pesticide, meaning it can be absorbed by plants and transported throughout their tissues. This quality makes it effective against pests that feed on both the surface and internal parts of crops. First introduced in the mid-20th century, carbofuran quickly became popular in agriculture due to its high potency and ability to increase crop yield by safeguarding against destructive infestations. However, despite its efficacy, carbofuran remains one of the most controversial pesticides because of its high toxicity to humans, wildlife, and the environment.

Mode of Action and Agricultural Applications

Carbofuran acts by inhibiting acetylcholinesterase, an enzyme critical for the proper functioning of the nervous system. By blocking this enzyme, carbofuran causes overstimulation of the nervous system in target pests, leading to paralysis and…
