Starting from the concept that many image forensic tools are based on the detection of some features revealing a particular aspect of the history of an image, in this work we model the counter-forensic attack as the injection of a specific fake feature pointing to the same history of an authentic reference image. We propose a general attack strategy that does not rely on a specific detector str...

Amino acids, for example L-arginine, are used in lyophilisation as crystalline bulking, buffering, viscosity reducing or stabilising excipients. In this study, arginine was formulated with different counter ions (hydrochloride, citrate, lactobionate, phosphate, and succinate). A monoclonal antibody investigated sugar-free formulations mixtures sucrose regarding cake appearance protein aggregati...

Self-dimerizations of twenty three aromatic carboxylate and sulfonate ions from their electrophoretic mobilities in aqueous solution were estimated by capillary zone electrophoresis (CZE). The magnitudes of the self-dimerizations ascribed to pi-pi interactions of these aromatic anions were determined by CZE as dimerization constants (KD). Although the largest KD value of 1.2 dm3 mol(-1) for 9-a...

The title complex, {[Fe(II)Y(III)(CN)(4)(NO(3))(C(10)H(8)N(2))(CH(3)OH)(3)]·CH(3)OH·0.5H(2)O}(n), is built up of ladder-like chains oriented along the c axis. Each ladder consists of two strands based on alternating Fe(II) and Y(III) ions connected by cyanide bridges. Two such parallel chains are connected by additional cyanide anions (the 'rungs' of the ladder), which likewise connect Fe(II) a...

Although there is now an increasing recognition of the existence of C -H -X (X = F, Cl, Br or I) hydrogen bonds in neutral organic molecules [1 , 2], there have been surprisingly few studies of C -H -X” interactions in organic salts. We have recently demonstrated the existence of extensive hydrogen bonding between aromatic C ~ H groups and halide ions, C -H X , within a series of imidazolium sa...

Simultaneous condensation reaction of thiocarbohydrazide with simple aromatic aldehyde and highly reactive ferrocenecarboxaldehyde resulted unusual unsymmentric Schiff bases associated multi metal ion sensing property. Spectral characterization methods indicate the formation new materials. Guest- host relationship established between various ions receptors changes electronic spectra drastically...
