This work proposes and analyzes the use of keystroke biometrics for content de-anonymization. Fake news have become a powerful tool to manipulate public opinion, especially during major events. In particular, massive spread fake COVID-19 pandemic has forced governments companies fight against missinformation. this context, ability link multiple accounts or profiles that such malicious on Internet while hiding in anonymity would enable proactive identification blacklisting. Behavioral can be...
Nanoparticle-doped polymer inclusion membranes (NP-PIMs) have been prepared and characterized as new materials for the removal of arsenate phosphate from waters. PIMs are made a polymer, cellulose triacetate (CTA), an extractant, which interacts with compound interest. We used ionic liquid (IL) trioctylmethylammonium chloride (Aliquat 336) extractant investigated how addition nanoparticles can modify membrane properties. To this end, inorganic nanoparticles, such ferrite (Fe3O4), SiO2 TiO2,...
A novel and environmentally-friendly procedure for the preparation of polymer inclusion membranes (PIMs) containing an ionic liquid is presented first time. Traditionally, PIMs are prepared by a solvent casting method with use harmful organic solvents. Here we report new solvent-free based on thermal-compression technique which involve melting components PIM application high pressure to melted specimen form flat-sheet film. In our study, have tested different polymers, such as two cellulose...
Surface characterization of polymer inclusion membranes (PIMs) using the polymers cellulose triacetate and polyvinyl chloride, containing different ionic liquids (ILs) as carriers, has been performed. Three ILs have tested: commercial trioctyl methylammonium chloride (Aliquat 336-AlqCl-) two derivatives bearing counter anion NO3- or SCN- (AlqNO3 AlqSCN, respectively). analysis was performed by scanning electron microscopy (SEM) X-ray photoelectron spectroscopy (XPS) for both dry PIMs...
A polymer inclusion membrane (PIM) containing the ionic liquid methyltrioctylammonium chloride (Aliquat 336) as carrier has been used satisfactorily for preconcentration of arsenate present in groundwater samples, allowing its determination by a simple colorimetric method. The optimization different chemical and physical parameters affecting performance allowed applicability to be broadened. transport As(V) was not affected make PIM (cellulose triacetate (CTA) or poly(vinyl chloride) (PVC))...
An X-ray fluorescence standardised inert dilution method has been developed for the determination of silica in quartz-sand, glass and cementclinker samples.By using fused sample technique, can be applied satisfactorily (standard deviation 0·7 per cent.) to rapid routine silica.The results determinations quartz sand are compared with those obtained by four different chemical methods.
