  • 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 ...

  • Electrochemical synthesis of polypyrrole for biosensor application

    Polypyrrole nanowires were electrochemically synthesised on platinum electrode at ambient temperature. The potentiostatic potential was set at 0.75 V in the presence of gelatin as soft mould. The whole process only took few hundred seconds. The morphologies, chemical composition and conductivity of nanowires were evaluated by means of Scanning Electron Microscopy (SEM), Fourier Transform Infrared ...

  • Alkaline deoxygenated graphene oxide as adsorbent for cadmium ions removal from aqueous solutions

    Alkaline deoxygenated graphene oxide (aGO) was prepared through alkaline hydrothermal treatment and used as adsorbent to remove Cd(II) ions from aqueous solutions for the first time. The characterization results of transmission electron microscopy, X-ray diffraction, Raman spectroscopy, and Fourier transform infrared (FT-IR) spectra indicate that aGO was successfully synthesized. The batch ...

  • Identification and quantification of methanol in contaminated spirits

    Introduction Over the past several years, an alarming trend has become evident, highlighting serious issues related to contaminated alcohol within the European Union, particularly Eastern Europe (1). This issue came to a breaking point in September of 2012 when the Czech Republic officially banned the sale of hard liquor after 20 people died from the consumption of methanol-laced ...

  • Optimising next-generation lithium ion batteries with infrared spectroscopy

    Lithium batteries have become the mainstay of modern portable electronics, providing a reliable power source to run mobile phones, laptop computers and electric vehicles. Lithium technology is now even being developed on a large scale to provide electricity storage to supplement the National Grid during peak demand [1]. The issue with lithium batteries remains the same – energy density ...

  • SnO 2 -Nafion ® nanocomposite polymer electrolytes for fuel cell applications

    Fuel cells are capable to exploit the combustion of hydrogen to convert chemical energy into electricity. Polymer electrolyte fuel cells based on Nafion membranes are able to work in a relatively low temperature range (70–90ºC) but require operating relative humidity (RH) close to 100%. To develop proton-exchange membranes with adequate performances at low RH, an attractive strategy ...

  • Deposition temperature effects on optical and structural properties of amorphous silicon carbide films

    Hydrogenated amorphous silicon carbide thin films (a–SiC:H) were elaborated by DC magnetron sputtering technique by using 6H–SiC as target. The a–SiC:H films of 0.9–1.5 µm thicknesses were deposited at different temperatures of 250, 350, 450 and 550°C on p–type Si(100) and Corning glass 9075 substrates. The deposited films (a–SiC:H) were investigated by Infrared Spectroscopy (FTIR), ...

  • Properties of CNT reinforced: PMMA nanocomposites and PMMA treated in NH3-gaseous atmospheric dielectric barrier discharge

    Polymethylmethacrylate (PMMA) polymer is a common dental laboratory and clinical material attracting various applications in plastic and adhesive dentistry. In direct contact with cellular tissues, PMMA may have toxic and inflammable properties which may limit use in contact with living dental tissues. By reinforcing PMMA with carbon nanotube and dielectric Nitrogen doping (in ammonia ...
