Preparation of magnetic nanoparticles and nanostructures has been achieved by both bottom-up and top-down approaches. Single domain MNPs show Néel-Brown-like relaxation. The Stoner-Wohlfarth model describes the angular dependence of the switching of the magnetization of a single domain particle in applied magnetic fields. By varying the spacing between the particles, the inter-particle interactions can be tuned. This leads to various supermagnetic states such as superparamagnetism, superspin glass, and superferromagnetism. Recently, the study of the magnetization dynamics of such single domain MNPs has attracted particular attention, and observations of various collective spin wave modes in patterned nanomagnet arrays have opened new avenues for on-chip microwave communications. MNPs have the potential for various other applications such as future recording media and in medicine. We will discuss the various aspects involved in the research on MNPs.

The utilization of graphene-based materials in the fabrication of nanocomposities with different polymer matrixes has been explored. This review article presents and discusses the development of graphene-based polymer composites and their applications in different fields such as electronics devices, energy storage, sensors, ESD and EMI shielding and biomedical applications.

They include mostly marine fungi and small group of terrestrial fungi and can be categorized into saprophytic, parasitic, and symbiotic fungi. Fungi in mangrove environment play an important ecological role in decomposition of organic matter by production of variety of extracellular degradative enzymes such as cellulase, xylanase, pectinase, amylase, and so on. Such enzymes can be isolated from the mangrove fungi and harnessed for several biotechnological applications. Several bioactive metabolites are derived from mangrove fungi, specially from mangrove endophytic fungi, which are used in pharmaceutical and nutraceutical industries to produce antimicrobial, anticancer, antioxidant, antidiabetic, and other therapeutic agents. Besides, certain mangrove fungi also contribute toward production of biopesticides useful in control of plant diseases, while others produce microbial lipids used as potential feed stock for biodiesel production. In spite of immense ecological role and biotechnological potentials, mangrove fungi are not extensively studied. The present review provides information on diversity and ecological role of mangrove fungi along with their biotechnological potentials as source of novel drugs, enzymes, biodiesel, biopesticides, and many other applications.
