Py/gc/ms Analyses of Historical Papers
The thermal degradation of cellulose is an important process in several fields such as the paper industry, biomass combustion, fire retardation, etc. Paper consists mostly of cellulose fibres. Although the fibre source has changed continiously from cotton or linen rags to wood, its nature is still vegetal. Pyrolysis in combination with gas chromatography and mass spectrometry has been used to i...
متن کاملBIOSORPTION OF Cu AND Zn BY IMMOBILIZED ALGAE BIOMASS OF CHLORELLA KESSLERI
Biosorption of heavy metals from aqueous solution can be considered as an alternative technology in industrial wastewaters treatment. This innovative process uses biomaterials which are either abundant in nature such as algae, fungus, bacteria, moss or wastes coming from industrial production and biological processes such as fermentation. The paper presents results of studies carried out on bio...
متن کاملAlteration of Nonlinear Refraction by Mixing Clusters [WOS3Cu3I(py)5] and [MoOS3Cu3I(py)5]
A new cluster compound [WOS3Cu3I(py)5] (I) was synthesized by substitution reactions of (Et4N)3[WOS3Cu3I4] with pyridine and structurally determined by X-ray diffraction. It crystallizes in monoclinic, space group C2/c (No. 15), a ) 24.341(1), b ) 10.020(4), c ) 26.64(1) Å, V ) 6424(3) Å3, and Z ) 8. The cluster has a nest-shaped skeleton. The nonlinear optical properties of both I and [MoOS3Cu...
متن کاملPyrolysis Characteristic of Tobacco Stem Studied by Py- GC/MS, TG-FTIR, and TG-MS
Pyrolysis characteristics and mechanism of tobacco stem were studied by pyrolysis coupled with gas chromatography/mass spectrometry (PyGC/MS), thermogravimetric analyzer coupled with Fourier transform infrared spectrometry, and mass spectrometry (TG-FTIR and TG-MS) techniques. The composition of evolved volatiles from fast pyrolysis of tobacco stem was determined by Py-GC/MS analysis, and the e...
متن کاملImproved cryptanalysis of Py
We improve on the best known cryptanalysis of the stream cipher Py by using a hidden Markov model for the carry bits in addition operations where a certain distinguishing event takes place, and constructing from it an “optimal distinguisher” for the bias in the output bits which makes more use of the information available. We provide a general means to efficiently measure the efficacy of such a...
