For more than a century, the Hofmeister Series has been an open problem in biophysics and colloid science. In this experiment, a standard viscometer has been used to test a section of the Series by comparing the viscosities of simulated egg white solutions after the addition of different salts (KCl,NaCl,MgCl2, CaCl2, LiCl and LiBr). Considering the obtained data, we have that the trend of the L...

A hybrid heat pump cycle of the heat amplifier type integrating a booster compressor between the generator and the condenser for distributed heating is simulated and analyzed. The interrelation between the two sub-cycles and the hybridization principle are explored. The theoretical analysis is demonstrated by a H2O/LiBr based hybrid cycle simulation. Investigation of the interaction mechanisms ...

Nonactivated phosphorylase kinase was dissociated to catalytically active lower molecular weight species by incubation with either ATP or LiBr at 0°C. Sucrose density gradient analysis showed that incubation with 100 m~ ATP produced 14 S and 7.5 S active forms and incubation with 1 M LiBr produced a 5 S active species. Large increases in the pH 6.8/8.2 activity ratio and loss of inhibition by E...

The water exchange process on fac-[(CO)3Mn(H2O)3]+ and fac-[(CO)3Tc(H2O)3]+ was kinetically investigated by 17O NMR as a function of the acidity, temperature, and pressure. Up to pH 6.3 and 4.4, respectively, the exchange rate is not affected by the acidity, thus demonstrating that the contribution of the monohydroxo species fac-[(CO)3M(OH)(H2O)2] is not significant, which correlates well with ...

The structural and energetic characteristics of O3–H2O complexes have been investigated by means of B3LYP, MP2, MP4(SDTQ), CCSD(T) and QCISD(T) methods in conjunction with the AUG-cc-pVDZ and AUG-cc-pVTZ basis sets. Six conformers were found for the O3–H2O complex. Two different intermolecular interactions were expected to participate in the formation of complexes, namely conventional O∙∙∙H hyd...

We report the interfacial properties of a new fluorocarbon-hydrocarbon hybrid surfactant [OH(CH2)11N(C2H4)2(CH2)2(CF2)5CF3 I, or FHUB], which has a fluorocarbon chain as well as a w-hydroxyalkyl chain. This new hybrid surfactant has properties that are different than classical hydrocarbonand fluorocarboncontaining surfactants. This difference is created by combining a fluorocarbon chain and the...

The acquisition of metastasis potential is a critical point for malignant tumors. Melanoma differentiation associated gene-7/interleukin-24 (mda-7/IL-24) is a potential tumor suppress gene and frequently down-regulated in malignant tumors. It has been implicated that overexpression of MDA-7 led to proliferation inhibition in many types of human tumor. Invasion is an important process which is p...

N-Metallated azomethine ylide generated from methyl (E)-N-benzylideneglycinate, LiBr and triethylamine underwent cycloaddition to quinolyl , -unsaturated ketones with excellent diastereoselectivity to afford new functionalised 3-pyrrolidinylquinoline derivatives.

The valence ionization and double ionization spectra of the water molecule, of the water dimer, and the cyclic water clusters (H2O)3 and (H2O)4 are calculated by ab initio Green's function methods and discussed in some detail. Particular attention is paid to the analysis of the development of the spectra with increasing cluster size. Electronic decay following inner valence ionization is addres...
