The Element Fluorine takes place in our Nature

By Ivane Care Baluran

    What will happen to us when fluorine will be takes place in our nature? What is the effect of fluorine not only for our nature but also to people?
     Fluorine is a non-metallic element. The presence of small quantities in water supplies has been found to promote strong resistance to dental decay.
     Fluorine is a robust element cannot be rebuffing it even though the glass laboratory apparatus when exposed in fluorine gas it will burn because of most violent properties. Yet, the fluorine help the industrial applications to prevent fuel tank diffusion not only that, but to supply sulphur hexafluoride. '
     Foremost of time fluorine has been identified of two Universities successfully the natural elemental fluorine in fluorspar this are Technisiche Universitaet Muenchen (TUM) and the Ludwid-Maximilliams-University Munich (LMU) according to Wikipedia.
    The chemist Friedrich Woehler and Justus Von Liebig was curious about the unpleasant and pungent smell. So, the two chemists proposed to study about the pungent smell of a fluorite.
     The 19F-NMR spectroscopy used to identify the presence of fluorine in our nature. When Florian Kraus of Department of Chemistry from (TUM) identified it they discovered that fluorine is non-destructively in our natural environment. There's no effect to human beings the fluorine when you know how careful handling the element especially when you conduct an experiment.

Nano – FTIR – The Brandest period in modern analytical Chemistry

By: Bernie Galve Non-invasive chemical mapping of materials with the use of the nanometer scale resolution is the ultimate objective in modern chemistry. There are different high-resolution techniques for imaging such as electron microscopy or scanning probe microscopy. In spite of this, the demands for modern chemical nano-analytics cannot be reached by the chemical sensitivity of these. For instance, an optical spectroscopy has higher level of chemical sensitivity but however it has low quality of resolution. This kind of resolution cannot give you a hundred percent kind of result you want. It is limited by means of diffraction to about half the wavelength. This prevents the nanoscale have resolved chemical mapping. With the use of nano-FTIR, mapping of materials and its nanoscale chemical identification become even more greater/ this is an optical techniques that joins the Fourier transform infrared (FTIR) and scattering-type scanning near-field optical microscopy (s-SNOM). The metalized tip of an atomic force microscope also known as AFM should be illuminate together with a broadband laser, and understanding the light which is backscattered with a Fourier Transform spectrometer that is specially designed, the researchers become more capable in demonstrating the local infrared and spectroscopy. This could be together with a spatial resolution of not more than 20 nm. “Nano-FTIR enables one for a reliable and fast chemical identification of almost any active material that is infrared on the nanometer scale”, says Florian Huth, who did the experiments. The good thing about this is that they are fit with the convential FTIR spectra. On the other hand the spatial resolution is increased with the use of not less than a factor of 300 differentiates to infrared conventional spectroscopy. The leader of the Nan optics group at nanoGUNE said that the high sensitivity to chemical composition combined with the ultra – high resolution. This makes this toll very unique for quality control, research and development in the polymer chemistry, pharmaceutical and biomedicine industry. Contamination of nano-FTIR on the chemical identification. A little sample contaminant can be seen on the next to a thin film of PMMA on a Sisubstrate which is the dark region. The contrast on the mechanical phase image indicates that the particles are composed of different materials than the substrate and film. Another example, for the chemical identification of nanoscale a nano-FTIR can be applied for sample of contaminations. The AFM phase of this can tell that there are 100 nm size contaminations. This determination of the chemical identity stills the same elusive. It can be determined as PDMS if they can record that the local infrared spectrum in the middle of the particle being compared to the standard FTIR spectra and its database are seen with the use of a nano-FTIR.
