We present a new capacitive sensor for displacement measurement in a Surface Forces Apparatus (SFA) which allows dynamical measurements in the range of 0 − 100 Hz. This sensor measures the relative displacement between two macroscopic opaque surfaces over periods of time ranging from milliseconds to in principle an indefinite period, at a very low price and down to atomic resolution. It consist...

We recently reported that a close relationship exists between alkane carbon-chain length, cell growth, and translocation frequency in Rhodococcus. In the present study, we examined the regulation of the spatial arrangement of cells in aqueous-alkane two phase cultures. An analysis of the effects of minerals on cell localization revealed that changes in the concentration of MgSO4 in two phase cu...

The asymmetric unit of the title co-crystalline adduct, 1,3,6,8-tetra-aza-tri-cyclo[4.4.1.13,8]dodecane (TATD)-4-iodo-phenol (1/2), C8H16N4·2C6H5IO, comprises a half mol-ecule of the aminal cage polyamine plus a 4-iodo-phenol mol-ecule. A twofold rotation axis generates the other half of the adduct. The components are linked by two inter-molecular O-H⋯N hydrogen bonds. The adducts are further l...

Water-soluble dinuclear Ru-arene complexes were synthesized and found to exert promising cytotoxic effects in human cancer cells, which could be increased to an IC50 of 0.29 μM by increasing the spacer length between the metal centers. Cytotoxicity could be correlated with lipophilicity (log P Values) and water solubility. The most potent dinuclear compound, 1,12bis{chlorido[3-(oxo-κO)-2-methyl...

In the title compound, C19H24N2O2, a di-Mannich base derived from 2-methyl-phenol and 1,3,6,8-tetra-aza-tri-cyclo-[4.4.1.1(3,8)]dodecane, the imidazolidine ring adopts a twist conformation, with a twist about the ring N-C bond [C-N-C-C torsion angle = -44.34 (14)°]. The two 2-hy-droxy-3-methyl-benzyl groups are located in trans positions with respect to the imidazolidine fragment. The structure...

The volatile compounds from various parts of Echinops ilicifolius (Compositae) such as flowers, leaves and roots obtained by hydrodistillation (HD) and headspace solid-phase microextraction (HS-SPME) methods were subsequently analysed by GC and GC/MS and compared. Thirty-seven and 20 components of the flower of E. ilicifolius were characterized, representing 99.7% and 100.0% of the total compos...

Surfaces that are strongly nonwetting to oil and other low surface tension liquids can be realized by trapping microscopic pockets of air within the asperities of a re-entrant texture and generating a solid-liquid-vapor composite interface. For low surface tension liquids such as hexadecane (gamma(lv) = 27.5 mN/m), this composite interface is metastable as a result of the low value of the equil...
