Graphene aerogels (GAs) are materials that combine the intriguing properties of graphene with the tunable 3-D nature of aerogel structure. The high surface area, porous structure, thermal and electrical conductivity, mechanical strength, and chemical stability of GAs are widely utilized in energy storage applications and environmental protection processes.Graphene aerogels are novel structures that have recently attracted attention due to their excellent intrinsic properties.Introduc …

As a silvery-white rare-earth metal, gadolinium (Gd) is a slightly malleable ductile chemical element categorized among the lanthanides in the periodic table of elements with the atomic weight and number of 157 and 64, respectively. Gadolinium engages in a gradual oxidation reaction with atmospheric moisture and oxygen. The magnetic property of gadolinium is time-dependent with ferromagnetic behavior at temperatures below 20°C (Curie point) and paramagnetic behavior at temperatures ab …

What Are Metal-Organic Frameworks? Metal-organic frameworks, commonly known as MOFs, are porous crystalline materials formed by connecting metal ions or metal clusters with organic linkers. This structure creates highly ordered networks with internal pores, channels and cavities that can host gases, ions, molecules or active chemical species. The main advantage of MOFs is their tunability. By changing the metal center, organic linker, pore size or surface chemistry, researchers can design MOFs f …

Cellulose occurs abundantly and naturally as raw material on Earth amounting billions of tons made by many different plant species. Technically, cellulose is a cheap, light-weight, thermally stable organic compound and one of the most common agents to meet the standards of sustainable chemistry since it is naturally biodegradable as well as renewable. Within plants, cellulose fibers are produced by microfibrils that are highly crystalline entity.Introduction In the past years, c …

Single-walled carbon nanotubes (SWCNTs) are one-dimensional allotropes of carbon atoms with sp2 hybridization prepared by rolling graphene sheets up to adopt a tubular morphology. In general, one, two or more rolls of graphene sheets are known as single- (SWCNTs), double- (DWCVTs) and multi-walled graphene nanotubes (MWCNTs), respectively.Technically, single-walled carbon nanotubes have found applications in various fields of science, technology, new-age nanoelectroic devices and ind …
