Metal-organic framework based nanomaterials: An advanced review of their synthesis and energy storage applications

Metal-organic frameworks (MOFs) have emerged as a versatile class of porous materials with enormous potential for various applications, including energy storage devices. In this review, we present a comprehensive analysis of the recent advancements and applications of MOFs in the field of energy storage. We begin by providing a brief overview of the fundamental aspects of MOFs, including their synthesis, structural diversity, and tuneable properties. We then focus on the utilisation of MOFs in advanced energy storage systems with a particular focus on supercapacitors. MOFs can be employed as electrode materials, separators, and catalysts, offering enhanced electrochemical performance, improved charge/discharge rates, and prolonged cycling stability. The unique tunability of MOFs allows for the rational design of tailored materials with desired properties, such as high specific capacity, excellent conductivity, and superior cycling stability. We will further discuss in detail the recent developments in MOF-based electrochemical capacitors, highlighting the significant progress made in achieving high energy and power densities. The exceptional charge storage capacity of MOFs combined with their facile synthesis and scalability make them promising candidates for next-generation energy storage technologies. The review further sheds light on the challenges and opportunities in the practical implementation of MOFs in energy storage devices with an eye on future research and development in the MOFs for energy applications. The manuscript discusses perspectives and future directions and, we believe, the insights presented are timely and will be of particular help to young and early-stage researchers

Dysprosium Acetylacetonato Single-Molecule Magnet Encapsulated in Carbon Nanotubes

Dy single-molecule magnets (SMMs), which have several potential uses in a variety of applications, such as quantum computing, were encapsulated in multi-walled carbon nanotubes (MWCNTs) by using a capillary method. Encapsulation was confirmed by using transmission electron microscopy (TEM). In alternating current magnetic measurements, the magnetic susceptibilities of the Dy acetylacetonato complexes showed clear frequency dependence even inside the MWCNTs, meaning that this hybrid can be used as magnetic materials in devices

A Critical Review on Materials for Solid Oxide Fuel Cell Components

Solid-oxide fuel cells are efficient devices for the conversion of chemical to electrical energy and a typical solid-oxide fuel cell consists of a solid electrolyte, cathode, and anode. In the last few decades, researchers have been working extensively on materials development for different components of these devices. In this review article, we briefly discuss the requirements for different components and review prominent materials families explored by the scientific community. As the search for greener energy alternatives such as solid-oxide fuel cells have intensified manifold due to the climate change emergency, a substantial literature was produced on the materials development of these devices and, therefore, we believe a brief review article dedicated to the same will be valuable for the scientific community, particularly new young entrant researchers in the field
