  • Preparation, characterisation and photocurrent study of sol–gel–derived Al, Mg–doped ZnO transparent thin films

    In this work, sol–gel spin–coating was employed to prepare ZnO, Al–doped ZnO (AZO) and Mg–doped ZnO (MZO) thin films onto glass substrates. Structural properties and surface morphologies of as–prepared films were characterised by X–ray diffraction (XRD) and scanning electron microscope (SEM) while their optical properties were scrutinised from their transmission spectra measured by UV–VIS ...

  • Growth and characteristic of high orientation indium nitride films grown on (100) silicon substrate

    In this study, high orientation InN films were prepared on Si (100) substrates using plasma–assist metal–organic molecular beam epitaxy (RF–MOMBE) system. These buffers include the nitrided treatment of the Si substrate, a low–temperature AlN buffer layer and oxide layer. The crystalline structure, surface morphology and optical properties of the InN films were characterised by X–ray diffraction ...

    S/CdS nanorod–array heterojunctions for efficient photoelectrochemical water splitting

    Oriented CdS nanorod arrays (NRAs) and their heteorojunctions formed with Ag2S nanoparticles have been successfully prepared via a one–step hydrothermal method and a successive ionic layer adsorption and reaction (SILAR) process. Their morphology, structural, and optical properties were characterised by scanning electron microscope, transmission electron microscopy, X–ray ...

  • Identification of forensic fabrics using a portable Raman spectrometer

    At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. While FTIR has been used for analysis in the past, the strong absorption of the fabric or the glass slide where it is mounted makes the spectrum very hard to interpret. In recent years, Raman spectroscopy has been studied extensively for ...

  • The metal binding potential of a dairy isolate

    Excess iron in water resources can lead to health hazards and problems. The ability of lactic acid bacteria to bind iron has not yet been widely studied. In the present study, sorption of iron ions from aqueous solutions onto lactic acid bacterium was determined. Elemental analyses were carried out by inductively coupled plasma optical emission spectrometry. The kinetics of Fe(III) biosorption ...

  • Feasibility of simultaneous surface topography and XRF mapping using Shear Force Microscopy

    Marketed sources equipped with polycapillary optics allow now laboratory X–Ray Fluorescence (XRF) analysis with 5–10 µm lateral resolution. To improve it, we had the idea to use a thin cylindrical X–ray capillary fitted to the XRF detector. The combination with near–field microscopy would then lead to a simultaneous record of both topography and XRF from a sample at µm lateral resolution. For ...

  • Nanomaterials applied in medicine, cultural heritage and chemical sensor technology

    Herein, we report three different analytical applications of multi–layers of oxidised graphene nanoribbons (GNOs). In the first section of this paper, the most significant results concern the effect of GNOs on the proliferation of NIH3T3 murine fibroblasts. Results show that GNOs represent the most biocompatible nanomaterials (compared with other ones, such as carbon black, single–wall carbon ...

  • The Benefits of Anti-Reflective Glasses

    Anti-reflective coating is also known as AR coating or anti-glare coating. The coating improves vision, reduces eye strain and makes the lenses appear invisible. These benefits are due to the ability of anti-reflective coating to virtually eliminate reflections from the front and back surfaces of your eyeglass lenses. With reflections gone, more light passes through your lenses to optimize vision ...

  • Understanding Laser Classifications and Output Levels

    Mainstream, low-powered lasers that emit continuous wave beams are harmless to humans. However, there are some lasers that can cause serious damage to one’s skin and eyes. To educate and protect people from using such lasers incorrectly – in a way that could cause injury – regulatory institutions have created a classification system that establishes the level of damage that the ...

  • Forensic micro-fiber evaluation using Microscopy | Spectroscopy Solutions

    Forensic investigations commonly involve the collection of textile fibers when examining crime scenes. The need to characterize and identify those fibers is vital as they can provide extensive information relating to a crime, tying a suspect to a location. Microscopic fibers in particular can present problems in terms of both size and quantity of sample. Fourier transform Infrared spectroscopy ...

  • REVO-2 and the ATOM encoder - Case Study

    The REVO multi-sensor system is one of Renishaw's flagship products and enables CMM users to perform 5-axis measurement on a 3-axis co-ordinate measuring machine (CMM). It measures 1000s of points/sec and operates at speeds up to 500 mm/s. As the head is much lighter and more dynamic than the CMM, it is able to quickly follow changes in the part geometry without introducing harmful ...

  • Industry under a microscope: improving the reliability and sensitivity of inline inspection tools improves overall pipeline integrity

    The oil and gas pipeline industry has been under close scrutiny for a long time. It leads the way as one of the most regulated industries in the world, and for good reason.  With so many safety-related, social and environmental factors at stake, comprehensive regulation ensures rigorous standards for the design, construction, operation and maintenance of O&G pipeline systems. Global ...
