Artificial weathering of tropical woods. Part 1: Changes in wettability
Authors: Kishino Masanori , Nakano Takato 
Published: August 2004

Abstract
Changes in the wettability of eight species of tropical woods during artificial weathering up to 600 h are discussed from the aspect of chemical and structural changes in their surfaces: Amnurana acreana, Acacia auriculiformis, Dipterocarpus spp., Eucalyptus marginata, Eucalyptus robusta, Shorea spp., and Tabebuia spp. with relatively high and low specific gravity. On the whole, the wettability of specimens decreased upon irradiation up to 20 h; above that they increased. Changes in wettability during artificial weathering differed according to wood species. The IR spectra suggest that the specimen surfaces after irradiation for 600 h result in a cellulose-rich layer, and therefore the increase in wettability during artificial weathering can be explained in terms of the increase in hydroxyl groups originating from both the exposed cellulose and adsorbed water. However, the difference in wettability exists between species even after the surface develops a cellulose-rich layer. The stereoscopic micrographs showed the development of cracks for all of the specimens after irradiation for 600 h, and differences in their magnitudes according to species. From these results, the differences in wettability between species were estimated to be due to the structural changes on the surface during artificial weathering, whereas the increase in wettability was due to the chemical changes.

Zusammenfassung

Zusammenfassung Die zellulären und molekulären Ereignisse in der Pathogenese der Arteriosklerose weisen Merkmale einer chronischen Entzündung auf und zeigen erstaunliche Ähnlichkeiten mit Autoimmunerkrankungen, wie rheumatoide Arthritis. Chemokine, Zytokine und ihre Rezeptoren spielen sowohl in der Frühphase, als auch in den fortgeschrittenen Stadien der Arteriosklerose eine Schlüsselrolle. Im vorliegenden Übersichtsartikel soll die wichtige Bedeutung der Chemokine und Zytokine als zentrale Biomarker bei der Entstehung und Perpetuierung der Arteriosklerose anhand aktueller Daten diskutiert werden.

Summary
A method was developed to determine activities and isotope ratios of plutonium and uranium. The method includes dry and wet ashing of air filters and separation of plutonium and uranium from each other and from other nuclides on Eichrom®´s extraction chromatography resins UTEVA and TRU. Interferences in plutonium separation caused by thorium and polonium were investigated and eliminated.
A field trial was performed in Kurchatov, Kazakhstan, to test the aerosol sampling and radiochemical methods developed for plutonium and uranium. In the air samples collected, the activity of 239,240Pu varied between 0.67 and 228 Bq/kg of dust, the activity of 238Pu from 0.20 Bq/kg to 16.4 Bq/kg of dust, and the isotopic ratio 238Pu/239,240Pu between 0.011 and 2.4. Concentrations of Pu isotopes in the air were 13.4-2490 nBq/m3 for 239,240Pu and 7.2-960 nBq/m3 for 238Pu. Radioactivity of 239,240Pu in air filters from Astana varied between 0.075 and 0.72 Bq per kg of dust and that of 238Pu between 0.038 and 0.14 Bq/kg of dust. Activity concentration of 239,240Pu in the air of Astana was 5.0-130 nBq/m3.

Authors: Karbowiak M. , Hubert S. , Fourest B. , Moulin Christophe 
Published: August 2004

Summary
The uranyl/periodate system was investigated by Time-Resolved Laser-Induced Fluorescence Spectroscopy (TRLIFS), and Capillary Electrophoresis (CE) in 0.1 and 0.05 mol L-1 perchloric solutions at pH 2.6, containing various amounts of periodate anions. The formation of only one complex, UO2IO4
+, was observed for a periodate concentration ranging from 5×10-5 to 10-1 mol L-1. The stability constant of this complex was estimated to be log β
11=1.8±0.2 by TRLIFS (fluorescence titration) and log β
11=2.0±0.2 by CE, for an ionic strength of 10-1 and 5×10-2 mol L-1, respectively. Moreover, the 1:1 stoichiometrical ratio between uranium(VI) and periodate was confirmed by an analysis of the results obtained from the deconvolution of fluorescence spectra.

Summary
Complexes of uranium(VI) and thorium(IV) with o-hydroxy N,N´-dimethylbenzylamine and o-carboxy N,N´-dimethylbenzylamine have been synthesized and characterized by elemental analysis, IR and 1H-NMR techniques. The coordination of metal ions with the ligand and their structures were established. The chemical and spectral properties revealed that uranium(VI) complexes have square bipyramidal structure for coordination number 6, and hexagonal bipyramidal structure for coordination number 8, whereas thorium(IV) shows bicapped square antiprism structure for coordination number 10.

Summary
Ion exchange properties of cesium, strontium and europium on uranium antimonate (USb) from nitric acid medium was studied. The distribution coefficient (K
d) of 1046 mL/g for cesium, 2464 mL/g for strontium and ∼105 mL/g for europium were obtained for sorption from 0.01 M nitric acid and K
d decreased with increase in the concentration of nitric acid. Rapid sorption of metal ions in the initial stages of equilibration followed by the establishment of equilibrium after 24 hours. Cesium sorption on USb follows ideal ion exchange while strontium and europium do not. From Langmuir adsorption model for the sorption of these ions on USb, the apparent sorption capacity was found to be of 6.9 mg/g for cesium, 19.1 mg/g for strontium and 37.2 mg/g for europium at 300 K. The enthalpy change (ΔH°) accompanied by the sorption was determined by the temperature variation method. The performance of the sorbent under dynamic conditions was assessed by following a breakthrough (BT) curve up to C/C
0=1. Extraction chromatography of individual ions from the mixture using USb was also reported in this paper.

Authors: Drebushchak Tatyana N. , Boldyreva Elena V. 
Published: August 2004

Abstract
The crystal structure of the orthorhombic polymorph of paracetamol was refined in Pbca space group by single-crystal X-ray diffraction at 100, 200, 300, 360 K. Cell parameters were measured in the range between 100 and 360 K. The anisotropy of lattice strain on cooling was analysed and compared with that induced by increasing pressure. The data for the orthorhombic paracetamol were compared also with the results previously reported for the monoclinic form of the same compound. The bulk thermal expansion coefficient of the orthorhombic polymorph is larger than that for the monoclinic form. Maximum compression on cooling was observed in the direction normal to the molecular layers. The structure expanded slightly on cooling in the crystallographic
a
-direction. Relative compressibility of OH…O and NH…O intermolecular hydrogen bonds on cooling, as well as the changes in the intramolecular geometry of paracetamol molecules and the atomic displacement parameters were measured and analysed.

Published: August 2004

AbstractDie einzigartigen Eigenschaften N‐heterocyclischer Carbene (NHCs) haben eine beachtliche Aufmerksamkeit vor allem seitens der theoretischen und metallorganischen Chemie auf sich gezogen. Insbesondere ihre Anwendung als Liganden in metallorganischen Komplexen wurde vielfach beschrieben. Weniger bekannt ist, dass sich NHCs auch hervorragend als Katalysatoren und nucleophile Reagentien eignen. So können NHCs beispielsweise in Umesterungen, nucleophilen aromatischen Substitutionen und Cycloadditionen eingesetzt werden. Asymmetrische Reaktionen in Gegenwart von chiralen NHCs als Katalysatoren ermöglichen die effiziente Synthese optisch aktiver Substanzen. Diese Aspekte der Chemie N‐heterocyclischer Carbene werden in diesem Kurzaufsatz näher betrachtet.

AbstractThe unique properties of N‐heterocyclic carbenes (NHCs) have attracted much attention, mainly from theorists and organometallic chemists, the latter using them impressively as ligands for metals. Less well known, however, has been their suitability as excellent catalysts and nucleophilic reagents. Transesterification, nucleophilic aromatic substitution, and cycloaddition reactions are examples in which NHCs can play an important role. Asymmetric reactions using catalytic amounts of chiral NHCs are an efficient approach to optically active compounds. This minireview focuses on this aspect of the chemistry of NHCs.

AbstractThe synthesis and spectroscopic characterization (infrared, 1H, 13C, 119Sn NMR and 119Sn Mössbauer) of three organotin derivatives incorporating carboxylate ligands, with general formulae (C6H11)2CHCOOSnPh3 (1), (CH3NH)C6H4COOSnPh3 (2) and 3,5‐(NO2)2C6H4CO2SnMe3 (3) are reported together with their X‐ray crystal structures. The compounds were obtained by the condensation, in ethanol, of the appropriate carboxylic acid with triphenyltin hydroxyde (1, 2) or trimethyltin hydroxide (3). In the case of triphenyltin(IV) derivatives, 1 and 2, the values of the Mössbauer quadrupole splitting and the infrared data [Δν = (νas(OCO) −νs(OCO)) > 230 cm−1] are consistent with the presence of monomeric species in the solid state. X‐ray crystallographic analysis confirms their structures as consisting of monomeric species, featuring distorted tetrahedral environments around the tin atoms. In both structures, one CSnC angle is relatively opened compared with the two others, which may be linked to the relatively close approach of the non‐bonding oxygen of the carboxylate ligand to the tin center (Sn(1)O(2) = 2.659(1) Å and 2.773(1) Å in 1 and 2 respectively). NMR data show the presence of monomeric species in solution, as found in the solid state. A significant intramolecular hydrogen bond is noticed between the hydrogen atom of the N‐methylanthranilate ion and the non‐coordinating oxygen atom in 2 (H(1A)O(2) = 2.06 Å, N(1)H(1A)O(2) = 132°). Infrared and Mössbauer spectroscopy and X‐ray diffraction have shown that 3 has an infinite chain structure in which the central tin atom adopts a distorted trigonal bipyramidal coordination with two oxygen atoms in axial positions, the three carbon atoms of the methyl group occupying equatorial sites. The 3,5‐dinitrobenzoate anions act as bidentate bridging ligands and the SnC3 moieties are asymmetrically trans‐coordinated (SnO(1) and SnO(2): 2.181(1) and 2.501(2)). 13C and 119Sn NMR data reveal a cleavage of the infinite chain structure of 3 in solution; the 119Sn chemical shift value (124.0 ppm), in conjunction with the magnitude of the coupling constant [2J(119SnCH) = 58.8 Hz; 1J(119SnC) = 393.6Hz], is consistent with a tetrahedral environment around the tin center.

Published: August 2004

AbstractNew trimethyltin(IV) derivatives with general formulae Me3Sn(HL), where HL is the monoanion of glycyltyrosine (H2L‐1), glycylisoleucine (H2L‐2), leucylleucine (H2L‐3), leucyltyrosine (H2L‐4), alanylvaline (H2L‐5), and valylvaline (H2L‐6) have been synthesized by the reaction of Me3SnCl and the sodium salt of the respective dipeptide with filtration of the NaCl formed. The bonding and coordination behaviour in the compounds synthesized are discussed on the basis of IR and 119Sn Mössbauer spectroscopic studies in the solid state and multinuclear 1H, 13C and 117Sn magnetic resonance in solution. These investigations suggest that, in the solid state, all the ligands in Me3Sn(HL) act as monoanionic bidentates coordinating through the COO− and NH2 groups. The 119Sn Mössbauer studies indicate that, for these polymeric derivatives, the polyhedron around tin in Me3Sn(HL) is a trigonal‐bipyramid with the three methyl groups in the equatorial positions, while the axial positions are occupied by a carboxylic oxygen and the amino nitrogen atom from the adjacent molecule. The NMR data suggest that, in solution, an equilibrium between solvated and intramolecular coordinated monomeric species exists. The anti‐inflammatory and cardiovascular activities and toxicity of all these compounds have been determined. All the compounds have also been screened against Staphylococcus aureus Mau (29/58), S. aureus Mau (78/71), Bacillus subtilis (18/64), Escherichia coli (326/71), E. coli, Candida albicans (Pn‐10), Microsporum gypseum and Euglena gracillis. All the Me3Sn(IV) compounds exhibit good anti‐inflammatory activity. Me3Sn(GlyTyr) and Me3Sn(GlyIle) display a potent cardiovascular activity and Me3Sn(AlaVal) exhibits good antibacterial activity against all the strains chosen.

Published: August 2004

AbstractA screening of 416 microorganisms from different taxonomical groups (bacteria, actinomycetes, yeasts, and filamentous fungi) has been performed looking for active strains in the stereoselective oxidation of secondary alcohols. The working collection was composed of 71 bacterial strains, 45 actinomycetes, 59 yeasts, 60 basidiomycetes, 33 marine fungi, and 148 filamentous fungi. All microorganisms selected were mesophilic. Yeasts were the most active microbial group in the whole‐cell‐catalyzed oxidation. Williopsis californica, Williopsis saturnus, and Pachysolen tannophilus were the strains of greatest interest, both as growing cells and as resting cells. The oxidation of the alcohols takes place when cells are in the stationary growth phase (after 48 h of culture). These three strains are S‐stereoselective for the oxidation of racemic secondary alkanols and show stereospecificity in the oxidation of menthol or neo‐menthol, whereas iso‐menthol is not oxidized. In the case of the 1‐tetrahydronaphtol enantiomers, only the S‐enantiomer is oxidized. The three strains were immobilized by entrapment using agarose and agar from algae of the Gracilaria genus. The agarose derivatives displayed significant improvement in the stereospecificity of the reactions. © 2004 Wiley Periodicals, Inc.
Adsorption of fluorescein by protein crystals

Published: August 2004

AbstractAdsorption characteristics of native and cross‐linked lysozyme crystals were examined using fluorescein as model adsorbate. The adsorption isotherms exhibited Langmuir or linear behavior. The affinity constant (b1) and the adsorption capacity (Qsat) for fluorescein were found to depend on the type and concentration of co‐solute present in the solution. The dynamics of adsorption isotherm transition from Langmuir to linear showed that affinity of lysozyme for solutes increases in the order 2‐(cyclohexylamino)ethanesulphonic acid (CHES), 4‐morpholinepropanesulphonic acid (MOPS), acetate, fluorescein. Furthermore, the crystal morphology, the degree of cross‐linking of the crystals, and, in particular, solution pH were identified as factors determining fluorescein adsorption by the lysozyme crystals. These factors seem to affect crystal capacity for the solute more than affinity for the solute. Adsorption of fluorescein by cross‐linked tetragonal lysozyme crystals was exponentially dependent on the lysozyme net charge calculated from the final solution pH. The 3–5‐fold increase in the fluorescein adsorption as a result of cross‐linking is presumably due to the increasing hydrophobicity of the lysozyme crystal. © 2004 Wiley Periodicals, Inc.
Extreme scale‐down of expanded bed adsorption: Purification of an antibody fragment directly from recombinant E. coli culture
Authors: Willoughby Nik , Martin Phillip , Titchener‐Hooker Nigel 
Published: August 2004

AbstractScale‐down is a methodology that combines the use of very small volumes of process fluid in dedicated devices to predict accurately the behaviour of process‐scale biotechnological unit operations and for the production of comparable material for use in further devices which, taken together, facilitate the mimic of a complete full‐scale process. This article provides the rationale behind the development of a small‐scale mimic and demonstrates the use of a highly scaled‐down expanded bed to predict hydrodynamic, kinetic, and adsorptive performance using less than 5‐mL sample volumes. Data acquired on a specially developed 1.9 mm ID column was compared with that obtained in a standard 25 mm ID column. A homogenised E. coli system expressing an antibody fragment (Fab) adsorbed onto an rProtein A matrix was used to characterise the full adsorptive performance. Breakthrough curve studies using BSA in buffer were used to characterise binding kinetics. Performance at the two scales was comparable both in terms of expansion, axial dispersion, binding isotherms, and elution behaviour of the antibody fragment. The eluted Fab material was further purified by ion exchange chromatography to demonstrate the similarity between the profile of the product material obtained at both scales. The high level of scale‐down (∼200‐fold) provides for rapid process evaluation early in development, where material is at a premium and where a fast appreciation of the likely merits of one process strategy will lead to greater confidence in process selection and more robust flowsheets. © 2004 Wiley Periodicals, Inc.
