Transition metal doped-CuO nanostructures have great potential to use in memory device applications. In the present work, we describe in detail, the synthesis of pure CuO, cobalt (Co) and manganese (Mn) doped CuO via low temperature co-precipitation method. Various techniques like; X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and Superconducting Quantum Interference Device (SQUID) magnetometer have been utilized to characterize the synthesized nanoparticles. XRD data exhibits a pure monoclinic phase of CuO for all synthesized samples. Surface morphology obtained from FE-SEM clearly shows the presence of cluster-like structure of grains. The magnetic investigations suggest that pure CuO nanoparticles exhibit the superparamagnetic state, which further transforms to antiferromagnetic state with Co doping. However, a peak of sharp intensity (maxima) at T = Tf in ZFC curve in Mn-doped sample gives the evidence of spin glass (SG) behavior.

Anthropogenic emissions of greenhouse gases (GHGs) have greatly amplified the level of greenhouse gases in the Earth's atmosphere which results in the gradual heating of the atmosphere. The precise measurement and reliable quantification of GHGs emission in the environment are of the utmost priority for the study of climate change. The detection of GHGs such as carbon dioxide, methane, nitrous oxide and ozone is the first and foremost step in finding the solution to manage and reduce the concentration of these gases in the Earth's atmosphere. The nanostructured metal oxide semiconductor (NMOS) based technologies for sensing GHGs emission have been found most reliable and accurate. Owing to their fascinating structural and morphological properties metal oxide semiconductors become an important class of materials for GHGs emission sensing technology. In th...

Various approaches are being applied to enhance the electrochemical performances of batteries and supercapacitors e.g. doping of transition metal ions, synthesis of composite materials, synthesis of nanomaterials, and surface modification of materials. Among these techniques, surface modification of the electrode materials is widely used because of ease of synthesis and cost effectiveness. In the present article, the recent advancements in surface modifications of the energy storage electrode materials and their electrochemical performances are summarized. First, coating strategies and their effects on cathode are discussed and then the current research progress focusing on the surface coating materials are covered. At last, the challenges faced are discussed to improve the performances of cathode materials. In this study, we are presenting that the selection of coating materials and technologies plays a vital role in the advancement of cathode materials.
