Carbon Nanotubes in Nanocomposite Mixed-Matrix Membranes
Carbon nanotubes (CNTs) are a popular material for gas separation because their walls are naturally smooth, allowing for faster gas transit than other inorganic fillers. It also has excellent mechanical strength, allowing membranes to work under high pressure. Although CNTs have superior qualities to other inorganic fillers, incorporating them into a polymer matrix is difficult due to CNTs' strong van der Waals forces, which cause agglomeration. CNT dispersion must be addressed if the full potential of CNTs is to be realized.

Covalent and Non-Covalent Interactions in Chitosan-Based Biomaterials
Chitosan (CS) is a natural biopolymer that has gained great interest in many research fields due to its promising biocompatibility, biodegradability, and favorable mechanical properties. Through covalent and non-covalent chemical modifications, CS derivatives can reach optimal properties for the development of smart biomaterials in a wide range of biomedial applications.

Applications of Nanoparticles
In recent times, metal oxide nanoparticles (NPs) have been regarded as having important commercial utility. However, the potential toxicity of these nanomaterials has also been a crucial research concern. In this regard, an important solution for ensuring lower toxicity levels and thereby facilitating an unhindered application in human consumer products is the green synthesis of these particles. Although a naïve approach, the biological synthesis of metal oxide NPs using microorganisms and plant extracts opens up immense prospects for the production of biocompatible and cost-effective particles with potential applications in the healthcare sector.

Electrospun Polymer Nanofibers
Electrospun polymer nanofibers constitute one of the most important nanomaterials with diverse applications. Nanofibers are classified as fibers with a ratio of length to thickness in the order of one thousand, or nanomaterials that have at least one dimension of 100 nm or less. A nanofiber with a diameter of ∼100 nm can have a specific surface area up to 1000 m2/g. Nanofibers can be produced by selecting the proper combination of polymers and additives, and using appropriate production techniques based on several essential characteristics that impact criteria of the intended particular application area. Electrospinning of polymer nanofibers is a widely used for investigation of their properties for uses in quite diverse applications. Attractive properties of electrospun nanofibers include the extremely high specific surface area, high porosity (typically 90%), light weight, controllable pore size, flexibility in surface functionalities, large permeability, excellent mechanical properties, high aspect ratio, and length up to many centimeters. Due to their exceptional characteristics, electrospun polymer nanofibers are used in many applications, which include biomedical technology, such as tissue engineering, wound healing and dressing, and drug delivery systems. In addition they have diverse uses in  sensors and biosensors applications, air filtration, defense applications, energy devices and protective textiles.

Modelling Metallic Magnetic Nanoparticles
Recent years have seen a significant growth in the use of metallic magnetic nanoparticles due to the versatile functionality which is intrinsically linked to their morphology, where both the particle size and shape contribute to the prominent magnetic features. The aim of this entry is to establish the predictive power of computational modelling in explaining these phenomena at the atomic level, allowing researches to find the link between the size, shape, and ligand-mediated property changes which will facilitate design of the tuning strategies for the realisation of application-specific magnetic behaviour at the nanoscale.

Mitotane Lipid Nanocarriers and Enantiomers
Emerging studies suggested that the S-(-)-mitotane is more potent than the R-(+)-mitotane for AdrenoCortical Carcinoma (ACC) treatment. Currently, mitotane is the only FDA-approved drug . Therefore, we suggest that the production of pure and active S-(-)-mitotane might offer synergic or additive benefits for ACC patients, and even better if combined to solid lipid-based nanocarriers, and smart/advanced nanocarriers.

Chinese Herb-Synthesized Silver Nanoparticles by Phytonanotechnology
Biologically synthesized silver nanoparticles (AgNPs) are potential antimicrobial agents commonly used in clinical treatment, such as wound dressing, topical ointments and anticancer agents. Recently, AgNPs with leaf and root extract ofPanax ginsenghave been successfully synthesized and showed potential antimicrobial activity. Different parts of Chinese herbs, including leaves, stenches, roots, and fruit extract, are widely applied for curing diseases.
