The Adsorption Of Nicotine On Calcinated And Modified Compressed Coffee Residue And Its Surface Properties [PDF]

open access: yesEgyptian Journal of Chemistry, 2018
A dried compressed coffee residue was calcinated at the temperature of 400 0C for 4 hours. It was analyzed quantitatively and qualitatively by using the X-Ray Fluorescence (XRF) spectroscopy. The coffee carbon surface was modified with oleum. The surface properties of the sample was studied by using the FTIR spectroscopy after each treatment resulting ...

The application of compressive sampling to radio astronomy I: Deconvolution

open access: yes, 2011
Compressive sampling is a new paradigm for sampling, based on sparseness of signals or signal representations. It is much less restrictive than Nyquist-Shannon sampling theory and thus explains and systematises the widespread experience that methods such
