Hydrogels are crosslinked polymer networks. The polymer structure of hydrogels exhibits great absorption capacity, swelling and shrinking behavior upon environmental changes and biocompatibility. Through different preparation methods and polymeric components, hydrogels can acquire different responsive behaviors. Hydrogels can be responsive to pH, temperature, solvent composition, enzymes, electric fields, and light.Click Image to Check Hydrogel ApplicationsOver the past decades, science h …

The element Graphene probably means nothing to you. However, it is part of the composition of one of the most common objects that is near you: a pencil. Graphene is a two-dimensional sheet of carbon atoms organized in a honeycomb structure and its stack forms the graphite of our pencil mines. Graphene was discovered in 2004 by two physicists, Andre Geim and Konstantin Novoselov when it was believed to be physically impossible. Graphene has incredible properties, to the point that it c …

Rechargeable batteries such as Li-ion batteries, Li-S batteries, and Na-ion batteries hold a great place in the development of renewable energy systems. The existent drawbacks of these batteries require novel solutions in order to meet expectations. Graphene is considered to be a promising material for these developments. The high conductivity, high surface areas, and mechanical flexibility of graphene are greatly utilized in rechargeable batteries.The ever increasing energy requirements …

Ultrafine anatase titanium dioxide nanoparticles and nanocrystals (TiO2) with average particle size of less than 100nm have ultra-violate (UV) radiation blocking properties as well as the ability to prevent photocatalytic reaction if they are coated with alumina and silica.Also, the titanium dioxide nanoparticles have applications in materials for construction purposes such as antifogging coatings and windows with self-cleaning quality. Titanium dioxide nanoparticle are referred as a safe …
