The chemical modifications of poly (vinyl chloride) with aliphatic and aromatic alcohols compounds have been investigated at room temperature and atmospheric pressure, catalysed by a new green basic catalyst, the Maghnite-K. The presence of ether groups in the products is proven by infra red spectroscopy (IR) as well as by nuclear magnetic resonance spectroscopy (1H NMR), and characterized by i...
A simple reaction process is developed to synthesize blue, green, yellow and red colour graphene nanoparticles (GNPs) from carbon fibers. Here, we have focused on synthesis of near infra-red GNPs and their biological application for optical imaging of deep tissues and organs.
We have obtained high resolution spectra (R ∼ 25000) of an A star over varying airmass to determine the effectiveness of telluric removal in the limit of high signal to noise. The near infra-red line He I at 2.058μm, which is a sensitive indicator of physical conditions in massive stars, supergiants, H II regions and YSOs, resides among pressure broadened telluric absorption from CO2 and water ...
Little use has thus far been made of the near infra-red spectrum for the identification and determination of hemoglobin and its derivatives BJ means of infra-red photography Eggert (1) established the transparency of carbon monoxide-saturated blood and used this property for the qualitative detection of carbon monoxide poisoning.. Eggert’s ‘observations were extended and placed on a more quanti...
tio2/zro2 nanocomposite was obtained by the sonochemical technique. in this method, two separate gels containing zirconium and titanium were prepared and mixed together. the precursor sol of zirconium was prepared from an aqueous solution of zrcl4. the precursor titanium tetra isopropoxide (ttip) dissolved in isopropanol. mixing of titanium and zirconium gels was resulted in a yellow tio2/zro2 ...

A combination of adsorption, microcalorimetry, infra-red spectroscopy and modeling has been implemented to reveal the potential of the H2S resistant amino-functionalized Ti MOF MIL-125 porous solid for the concomitant elimination of CO2 and H2S from biogas and natural gas.
