Treatment of [(PCy3)2Cl2Ru=CH-Ph] (I) with vinylferrocene 1 and 1-ferrocenyl-1,3-butadiene 2 yielded solid products. These new complexes were characterized by 1H NMR, 31P NMR and 13C NMR spectroscopy. X-ray crystal structures of both the complexes have been solved. The crystal structure of II confirmed the assigned structure and revealed existence of two sets of intermolecular C-H-Cl(M) type interactions, viz. (Ru)Cl-H-C(ferrocene) and (Ru)Cl-H-CHCl2. The air-stable, dark solid II is an efficient catalyst for ring-opening metathesis polymerization (ROMP) of cyclopentene, norbornene and cycloocta-1,5-diene. Electrochemical behavior of the complexes clearly reflects electronic communication between two metal centers.

Accurate and detailed measurements of average magnetic susceptibility (4-100 K) and magnetization (2-20 K and 10-50 kOe)) are reported on a number of high spin iron (III) porphyrins, namely protoporphyrin-, octaethylporphyrin-, and deuteroporphyrin iron (III) chlorides.Adequate percautions were taken to ensure that the crystallities did not orient during the magnetization measurements, in high magnetic fields at low temperatures.The experimental magnetization data show complete saturation below 4 K at magnetic fields above 40 kOe and the saturation moment lies between 3.0-3.4 in these compounds. indicating large deviation from the expected value of 5.0, due to sizeable zero-field splitting.The magnetization results at low temperatures show varying degrees of exchange interaction, which was considered within molecular field framework to quantitatively account for the data.A fit to the data gave reasonable values for the zero-filed splitting and exchange-interaction parameters.

Cation transport through a cellulose acetate-poly(N,N-dimethylaminoethyl methacrylate) membrane (CA:PDMAEMA) was studied with scanning electrochemical microscope (SECM) and the thickness increase of the membrane was monitored with ellipsometry. Upon addition of the polyelectrolyte PDMAEMA, the permeability of the probe cation (ferrocenium methanol, FcMeOH) was increased as much as 40-fold. Soaking membranes in an electrolyte solution doubled the permeability in plain CA membranes, whereas for PDMAEMA containing membranes the opposite was observed and the permeability was reduced by 20?40%. This time-dependent behavior is shown to be a result of the presence of PDMAEMA within the membrane matrix, thus providing an interesting platform for controllable membrane permeability.

We report an innovative supramolecular architecture for bienzymatic glucose biosensing based on the non-covalently functionalization of multi-walled carbon nanotubes (MWCNTs) with two proteins, glucose oxidase (GOx) (to recognize glucose) and avidin (to allow the specific anchoring of biotinylated horseradish peroxidase (b-HRP)). The optimum functionalization was obtained by sonicating for 10 min 0.50 mg mL?1 MWCNTs in a solution of 2.00 mg mL?1 GOx+1.00 mg mL?1avidin prepared in 50 : 50 v/v ethanol/water. The sensitivity to glucose for glassy carbon electrodes (GCE) modified with MWCNTs-GOx-avidin dispersion and b-HRP (GCE/MWCNTs-GOx-avidin/b-HRP), obtained from amperometric experiments performed at ?0.100 V in the presence of 5.0×10?4 M hydroquinone, was (4.8±0.3) muA mM?1 (r2=0.9986) and the detection limit was 1.2 muM. The reproducibility for 5 electrodes using the same MWCNTs/GOx-avidin dispersion was 4.0 %, while the reproducibility for 3 different dispersions and 9 electrodes was 6.0 %. The GCE/MWCNT-GOx-avidin/b-HRP was successfully used for the quantification of glucose in a pharmaceutical product and milk.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.

This work proposes the use of an electronic tongue based on flow injection coulometry for the rapid determination of the antioxidant capacity of fresh lettuce. The e-tongue consisted of a series of 16 porous carbon electrodes, each poised at a fixed potential from +100 to +850 mV. Each injection leaded to a characteristic hydrodynamic voltammogram, whose profile reflects the composition of antioxidants. The correlation between the peak area recorded by each sensor and the 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) assay was maximum in the range of potentials between +400 and 750 mV (R2>0.97). Accordingly, the charge measured provided a direct and simple index of the antioxidant capacity. The practical utility of such index was initially demonstrated by determining the best extraction conditions. This consisted in freeze-drying of lettuce followed by methanolic extraction. Later, the e-tongue was used to evaluate the effect of storage (one week at 5 C) on lettuce. The e-tongue revealed that lettuce lost up to 25 % of their initial antioxidant activity during storage. However, when lettuce samples were pre-treated with fast cooling or vacuum cooling, the decrease of the antioxidant index was limited to 14 and 15 %. Overall, the e-tongue is a rapid, simple and sensitive method for the determination of the antioxidant capacity of fresh lettuce samples. Indirectly, these findings suggest also that lettuce may serve as potential dietary sources of natural phenolic antioxidants.
