Authors: Notz R. , Tönnies I. , Scheffknecht G. , Hasse H. 
Published: September 2010

AbstractEs wird ein Überblick über den aktuellen Stand der Verfahrenstechnik zur Entwicklung von Kraftwerken mit drastisch reduziertem Ausstoß von Kohlendioxid gegeben. Die drei Haupttechnologien Post‐Combustion Capture, Pre‐Combustion Capture und Oxyfuel‐Technologie werden kurz vorgestellt und auf Basis neuerer Literatur miteinander verglichen. Wesentliche Vorteile der Post‐Combustion Capture sind die Möglichkeit der Nachrüstung bestehender Kraftwerke sowie die Technologiereife der Reaktivabsorptionsverfahren, die eine mittelfristige Umsetzung ermöglichen. Mit den beiden anderen Technologien ergeben sich nach dem derzeitigen Kenntnisstand voraussichtlich etwas geringere Wirkungsgradverluste des Kraftwerks, die Nachrüstbarkeit mit der Oxyfuel‐Technologie ist mit größerem Aufwand verbunden, die Pre‐Combustion Capture ist nicht nachrüstbar. Bei allen Technologien besteht weiterhin hoher Forschungsbedarf. Auf die Post‐Combustion Capture durch Absorption wird aufgrund des großen Potenzials für die mittelfristige Anwendung näher eingegangen.

AbstractA new cadmium (II) coordination polymer, [Cd(TTTMB)2]‐(SO4) · 21H2O, where TTTMB =1,3, 5‐tris (imidazol‐1‐yl‐methyl)‐2,4,6‐trimethylbenzene, was obtained by self‐assembly of tripodal ligand TTTMB with CdSO4·2.7H2O in acetonitrile, and characterized by X‐ray crystallography. The crystal data belongs to monoclinic space group Cc with cell parameters a = 1.16891(4) nm, b=2.06671(6) nm, c = 2.48185(7) nm, β = 97.8560(10)°, R = 0.0487, wR = 0.1211. The results of structure analysis indicate that each TTTMB ligand coordinates three metal atoms and in turn each Cd(II) atom with octahedral coordination geometry connects six nitrogen atoms of imidazole group from six different TTTMB ligands to produce a 2D honeycomb network structure. There are a lot of water molecules linked by hydrogen bonds and occupied the channels formed intra‐ and inter‐sheets.

Published: September 2010

AbstractThere are two theories, SN1 and SN2, for the mechanism of the deaquation of aquopentaamincobalt (III) bromide (AAC‐B). Both of the theories are supported by some experimental and calculated data. But there are not any experiments to determine directly the structure of the intermediates at different reaction tune. In this paper the structures of the intermediates at different reaction time in deaquation‐anation of AACB were determined by extended X‐ray absorption fine structure (EXAFS) and the reaction process was studied by the combination of X‐ray powder diffraction and EXAFS. It was demonstrated that the deaquation‐anation of AACB obeys the SN2 theory.

Mild reaction conditions, excellent yields as well as the environmentally friendly character of La(OTf)3 make it an important alternative to the classic acid‐catalyzed Biginelli's reaction.

Authors: Pei Ren‐Jun , Cui Xiao‐Qiang , Yang Xiu‐Rong , Wang Er‐Kang 
Published: September 2010

AbstractAn automated biomolecular interaction analysis instrument (BI‐Acore) based on surface plasmon resonance (SPR) has been used to determine human immunoglobulin G (IgG) in real time. Polyclonal and‐human IgG antibody was covalently immobilized to a carboxymethyldextran‐modified gold film surface. The samples of human IgG prepared in HBS buffer were poured over the immobilized surface. The signal amplification antibody was applied to amplify the response signal. After each measurement, the surface was regenerated with 0.1 mol/L H3PO4. The assay was rapid, requiring only 30 min for antibody immobilization and 20 min for each subsequent process of immune binding, antibody amplification and regeneration. The antibody immobilized surface had good response to human IgG in the range of 0.12–60 nmol/L with a detection limit of 60 pmol/L. The same antibody immobilized surface could be used for more than 110 cycles of binding, amplification and regeneration. The results demonstrate that the sensitivity, specificity and reproducibility of amplified immunoassay using real‐time BIA technology are satisfactory.

Theoretical Study on the Kinetics of Electron Transfer for Bond‐breaking Reaction
Authors: Xing Yu‐Mei , Zhou Zheng‐Yu , Gao Hong‐Wei 
Published: September 2010

AbstractTo test the theory of dissociative electron transfer, a simple model describing the kinetics of electron transfer bond‐breaking reactions was used. The Hamiltonian of the system was given. The homogeneous and heterogeneous kinetic data fit reasonably well with an activation‐driving force relationship derived from the Marcus quadratic theory. In the heterogeneous case, there is a good agreement between the theoretical calculation and the experimental result, while in the homogeneous case, a good agreement is only observed for the tertiary halides. This is due to the stability of tertiary radical resulting from the sterical effect.

Authors: Yue Shan‐Tang , Liao Wu‐Ping , Li De‐Qian , Su Qiang 
Published: September 2010

AbstractThe kinetics of RE (La, Gd, Er, Yb and Y) extraction with sec‐octylphenoxy acetic acid was investigated using a constant interfacial area cell with laminar flow at 303 K. The natures of the extracted complexes have some effect on the extraction rate which is controlled by the reaction rate of M(III) and extractant molecules at two‐phase interface for Er(III), Yb(III) and Y(III), by a mixed chemical reaction‐diffusion for Gd (III) and a diffusion for La(III). The extractant molecules tend to adsorb at the interface. So an interfacial extraction reaction model was derived.

Published: September 2010

AbstractTwo palladium(II) complexes, [Pd(bipy)(BzPhe‐N,O)] and [Pd(phen)(BzPhe‐N,O)]·4H2O were synthesized by reactions between Pd(bipy)Cl2 and BzPheH2 (N‐benzoyl‐β‐phenylalanine), Pd(phen) Cl2 and BzPheH2 in water at pH‐9, with their structures determined by X‐ray diffraction analysis. The Pd atom is coordinated by two nitrogen atoms of bipy (or phen), the deprotonated amido type nitrogen atom and one of the carboxylic oxygens of BzPhe (BzPhe = N‐benzoyl‐β‐phenylalaninate dianion). In the complex [Pd(phen) (BzFne‐N,O)] · 4H2O, the side chain of phenylalanine is located above and approximately parallels to the coordination plane. Both the aromatic‐aromatic stacking interaction between the phenyl ring of phenylalanine and phen, and the metal ion‐aromatic interaction between the phenyl ring of phenylalanine and Pd(II) were observed. [Pd(bipy)(BzPhe‐N,O)] has the phenylalanyl side chain oriented outwards from the coordination plane, which is mainly due to the interaction between the carbonyl oxygen atom of the amido group and the phenyl ring of phenylalanine. The reason for the different orientation of phenylalanyl side chain in the complexes was suggested.

AbstractThe techniques of oxygen electrode polarography and Fourier transform infrared (FT‐IR) spectroscopy were employed to explore the involvement of digalactosyl diacylglycerol (DGDG) in functional and structural roles in the photosystem II core complex (PSIICC). It was shown that DGDG exhibited the ability to stimulate the oxygen evolution in PSIICC, which was accompanied by the changes in the structures of PSIICC proteins. The results revealed that there existed hydrogen‐bonding interactions between DGDG molecules and PSIICC proteins. It is most likely that the sites of PSIICC interaction with DGDG are in the extrinsic protein of 33 kDa.

Authors: Fan Jian‐Fen , Xiao He‐Ming , van De Graaf B. , Wang Qiu‐Xia , Njo S. L. , Xia Qi‐Ying 
Published: September 2010

AbstractMolecular dynamics simulation has been performed for studying the polarization and electronegativity of ethene molecules near Brönsted acidic sites in H[Al] ZSM‐5. The result shows that the molecules are polarized most at the edges of intersections and least at the segments of channels. On the contrary, the highest global molecular electronegativity is found at the centers of channel segments. Al substitution slightly increases the molecular dipole moment, but hardly affects the molecular electronegativity. Brönsted acidic proton decreases the dipole moment of guest molecule, but increases the molecular electronegativity.

Published: September 2010

AbstractA microcalorimetric technique was used to investigate the influence of Zn2+ on the growth metabolism of Bacillus thuringiensis. LKB‐2277 Bioactivity Monitor was employed to obtain the power‐time curves, from which the maximum peak‐heat output power (Pmax) in the log phase, the growth rate constants (k), the inhibitory ratios (I), the generational time (tG) and the total heat effect (Qtotal) in 23 h for the growth metabolism of Bacillus thuringiensis at 28 °C can be evaluated. The results indicate that the concentration of Zn2+ affects its growth obviously. Low concentration (0–50 μg/mL) of Zn2+ promotes the growth of Bacillus thuringiensis while high concentration (50–500 μg/mL) of Zn2+ inhibits its growth. When the concentration reached up to 600 μg/mL, it can not grow at all.

AbstractThree palladium (II) complexes with the isonitrosobenzoylacetoneimine (HIBI) ligand, Pd (p‐CH3C6H4IBI)2 (1), Pd (C6H5IBI)2 (2) and Pd2Cl2 (C6H5CH2IBI)2 · CHCl3 (3), were prepared and characterized by IR, Raman and X‐ray diffraction studies. The geometries around the palladium atoms in the complexes 1 and 2 are distorted trans‐PdN4 square planes, and the Schiff base ligands RIBI− are coordinated through their oximo‐nitrogen atoms and imino‐nitrogen atoms. The week Pd…HC agostic interactions [Pd…H = 0.2764 nm] complete the hexacoordinate environment around palladium in the complex 1. The octahedral deformation of the classical square planar environment of the Pd atom is due to the week Pd…O (1b) interactions [PdO (1b) = 0.3157 (9) nm] in the complex 2. The complex 3 is a first example of binuclear complex with isonitrosoketoimine ligands, in which one of oximo groups is coordinated through oximo‐nitrogen and oximo‐oxygen atoms.

The second structural feature of complex 3 is the τ‐τ stacking interaction between two adjacent molecular planes, which forms the two‐dimentional layer structure. Besides, compared with 2, the luminescent intensity of complex 3 shows a remarkable enhancement.
