Nanocomposite Hydrogels for Water Purification
Abstract: DNA hydrogels have been demonstrated as versatile catalysts, potential adsorbents, sensors and immobilization carriers of bioactive molecules. They are a type of tenuous, semiflexible polymeric network that consists of precisely designed synthetic nucleotide strands as chemical or physical cross-linkers. Hydrogels have been widely studied due to their improved physicochemical properties and used as antibacterial platforms, wastewater pollutants, adsorbents and drug deliverers. Because of their biocompatibility and the ability to mix …

Bioplastics: A Review
Abstract: Plastics made from renewable biomass sources and some have been produced by processing natural biopolymers. Biodegradable bioplastics can be used to reduce the problem of plastic waste materials, which is choking the planet and damaging the ecology. The advantage of bioplastics is that they are not dependent on fossil fuels as a source of raw material. With regard to oil production, fossil fuels are a finite and irregularly divided resource …

Studies on Interaction of SDS with HPMC Using Central Composite Design
Abstract: The conductivity measurements were used to study the interaction between non-ionic biopolymers, hydroxypropyl methyl cellulose (HPMC) and the anionic surfactant- sodium dodecyl sulphate (SDS) in aqueous solutions of different concentrations and at temperatures along with the use of Response Surface Methodology (RSM). Calculations were made of the free energies of aggregation ΔGagg, micellization (Gmic), and transfer (Gt), all of which are connected to the bonding interaction between the surfactant and …

Macro-compounds and Macro-cycles with Their Applications
Abstract: Macro-compounds represent an ancient class of compounds that enter into coordination chemistry as a ligands such as (crown ethers, aza, thia and others), or in the field of organic chemistry through large cyclic compounds such as porphyrins, vitamins and others, where corona ethers are strongly linked with specific cations forming coordination complexes, In which the oxygen atoms occupy positions suitable for coordination with a cation located inside the ring, and …
