The relationship between crystal and molecular structure of the pairs of isomers in the ‘merry-go-round’ process [Ir4(CO),(p,-$CH,SCH2SkH2)] 1 and [Ir,(CO),(p-CO),(p,-$CH,SCH2SkH2)] 2, and of the ionic species [NMe,(CH,Ph),] [Ir,(CO),,(SCN)] 3 and [N(PPh,),] [Ir,(CO),(p-CO),(SCN)] 4 has been investigated by means of atom-atom potential-energy calculations and packing analysis. It has been shown...

Choline saccharinate and choline acesulfamate are two examples of hydrophilic ionic liquids, which can be prepared from easily available starting materials (choline chloride and a non-nutritive sweetener). The (eco)toxicity of these ionic liquids in aqueous solution is very low in comparison to other types of ionic liquids. A general method for the synthesis and purification of hydrophilic ioni...

Quartz Crystal Microbalance (QCM) biosensor technology was used to study the interaction of the DNA-binding domain (DBD) of the transcription factor RXRα with immobilized specific (DR1) and unspecific (DR1neg) DNA oligoduplexes. We identify the QCM sensor frequency at the susceptance minimum (fBmin) as a better measuring parameter, and we show that fBmin is proportional to the mass adsorbed at ...

In this paper, the pulping process of wheat straw using ionic liquid 1-ethyl-3-methylimidazolium bromide ([Emim]Br) as the digestion liquor is presented. The influence of pulping conditions on the pulp yield are analysed by single-factor and orthogonal experiments, and optimum pulping conditions are obtained. The average pulp yield reaches 44 %, and the average recovery rate of ionic liquid is ...

High-level quantum-chemical calculations, using the coupled-cluster approach and extended one-particle basis sets, have been performed for (Mg)n(O )m clusters embedded in a Madelung potential. The results of these calculations are used for setting up an incremental expansion for the correlation energy of bulk MgO. This way, ∼ 96% of the experimental cohesive energy of the MgO crystal is recover...

The in uence of the ionic adsorption on the anchoring energy of a nematic liquid crystal sample is investigated. We determine the behavior of the anchoring energy as a function of the thickness of the sample, and as a function of the adsorption energy of ions. We show that the contribution to the anchoring energy, due to ionic adsorption, can be of the same order of magnitude of the bare anchor...

A series of novel ionic liquids composed of imidazolium, pyridinium, pyrrolidinium, and ammonium cations with tricyanomethanide or tetracyanoborate anions were prepared. The ionic liquids were characterized by NMR and IR spectroscopy and ESI-mass spectrometry, and their physical properties were investigated. Solid state structures of the N-propyl-N-methylpyrrolidinium and triethylpropylammonium...

In the title compound, [MeC5H4NCONHCH2C6H5]I or C14H15N2O+·I-, a cation and an anion form an ionic pair linked by a strong N-H⋯I hydrogen bond. In the crystal, ionic pairs linked by weak C-H⋯I hydrogen bonds form infinite ribbons along the crystallographic a axis. Polymorphism screening varying crystallization solvents (water, acetone 90%-water, ethanol 90%-water, 2-propanol 90%-water, DMF, DMS...

The Li+ ion diffusion coefficient of lithium iron phosphate LiFePO4 cathode materials should not be measured by the standard method because there is no composition variation but the movement of the LiFePO4/FePO4 interface during Li insertion/ extraction. A method to measure the intrinsic electronic and ionic conductivity of mixed conductive LiFePO4 was reported, for the first time, based on the...
