The present work explores the effect of minor additions of 0.1%Hf and 0.15%Zr in Al-2%Cu (all in at.%) processed through chill-casting followed by a three-stage heat treatment schedule towards designing a high strength, high-temperature Al–Cu-based alloy. The three-stage heat treatment involves direct aging at 400 °C, followed by solutionising at 5...

Incorporating structural coloured materials in flexible and stretchable elastomeric substrates requires numerous steps that compromise their scalability and economic viability for prospective applications in visual sensors and displays. Here we describe a one-step approach for fabricating plasmonic Ga nanostructures embedded in a polydimethylsiloxa...
Chapter
Lightweight magnesium (Mg) alloys attract great attention for automotive applications, especially in power train components. It acknowledges the potential of rare earth elements, specifically cerium (Ce), as an alloying addition to enhance the mechanical properties of Mg alloys at both room and high temperatures. However, its precise role is not ye...

Mixed ferrite nanoparticles with compositions CoxMn1-xFe2O4 (x = 0, 0.2, 0.4, 0.6, 0.8, and 1.0) were synthesized by a simple chemical co-precipitation method. The structure and morphology of the nanoparticles were obtained by X-ray diffraction (XRD), transmission electron microscope (TEM), Raman spectroscopy, and Mössbauer spectroscopy. The averag...

Graphene oxide based magnetic nanocomposite (GO-Fe 3 O 4 ) was synthesized using the coprecipitation method. Intercalation of nanoparticles has resulted in the modified interlayer spacing of GO sheets, it is increased from 0.82 to 1.11 nm. Nanocomposite was characterized using TEM, AFM, XRD, UV-Visible and Raman spectroscopy. Magnetic nanocomposite...

The study presented in this work consists of two parts: The first part is the synthesis of Graphene oxide-Fe3O4 nanocomposites by a mechanochemical method which, is a mechanical process that is likely to yield extremely heterogeneous particles. The second part includes a study on the efficacy of these Graphene oxide-Fe3O4 nanocomposites to kill can...
