Imaging and diffraction characterisation of 2D inorganic nanostructures

Surface Hardness Measurment and Microstructural Characterisation of Steel by X-Ray Diffraction Profile Analysis

An X-ray diffraction line will broaden considerably when steels change into martensitic structure on quenching. The results presented in this paper show that X-ray diffraction technique can be employed for a rapid and nondestructive measurement of hardness of hardened steel. Measurement on various quenched and tempered steels showed that the breadth of its diffraction peak increased with increa...

Inorganic Nanostructures Decorated Graphene

Coupled organic-inorganic nanostructures (COIN).

In this perspective, we provide an overview of the emerging field of coupled conjugates of quantum dots and organic semiconductors, referred to as "coupled organic-inorganic nanostructures" (COIN). We summarize important aspects of their optical properties and highlight suitable descriptions of their electrical transport behavior. In particular, we discuss the key role of the electronic structu...

Interactive Diffraction from Biological Nanostructures

We describe a technique for interactive rendering of diffraction effects produced by biological nanostructures, such as snake skin surface gratings. Our approach uses imagery from atomic force microscopy that accurately captures the geometry of the nanostructures responsible for structural colouration, that is, colouration due to wave interference, in a variety of animals. We develop a renderin...

Effect of Sn Doping on Structural and Optical Properties of 2D α-MoO3 Nanostructures

Undoped and Tin (Sn) doped Molybdenum trioxide (α-MoO3) nanostructured thin films (which has lamellar (2D) structure) have been prepared using a simple and cost effective technique of spray pyrolysis on glass substrates at 450 ℃. Surface morphology, optical and structural properties of samples have been investigated using FESEM, UV-Vis spectroscopy and XRD analysis techniques, respectively. FES...
