Published: December 2010

AbstractA series of ultraviolet (UV)‐curable, boron‐containing hybrid coatings were prepared by an anhydrous sol–gel technique from a mixture of an acrylated bisphenol A based epoxy resin, methacryloxymethyl triethoxysilane, and boric acid. The use of boric acid allowed the hydrolysis and condensation of hybrid silicon alkoxides without the further addition of water or a catalyst. The chemical structure of the boron‐containing hybrid coatings was characterized with Fourier transform infrared, real‐time infrared, and 29Si cross‐polarization/magic‐angle spinning NMR techniques. UV‐curable coatings were applied to polycarbonate and Plexiglas substrates. The physical and mechanical properties of the UV‐cured coatings (e.g., pendulum hardness, pencil hardness, contact angle, gel content, methyl ethyl ketone rubbing test, tensile test, abrasion resistance, chemical resistance, neutron absorption, and limiting oxygen index) were examined. The hybrid coatings showed a significant enhancement in their radiation‐shielding properties. The thermal behavior of the coatings was also evaluated. It was observed that the thermal stability of the coatings mainly depended on their boron and silicate contents. The results of all analyses of the free films and coatings were examined. © 2010 Wiley Periodicals, © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Dendrimer finishing influence on CO/PES blended fabrics color assessment
Authors: Colleoni Claudio , Massafra Maria Rosaria , Migani Veronica , Rosace Giuseppe 
Published: December 2010

AbstractTextile finishing includes all processes that help to maintain the value or increase the value of the textile material. It encompasses dyeing, printing, and all the finishing treatments to realize durable press, soil release, flame retardant, antistatic, antimicrobial, or water/oil repellency properties. When these properties are realized on dyed textile fabric, one effect could be ascribed to the color change induced by finishing operations. This research focuses on the assessment of color alterations occurring on the dyed cotton/polyester blended fabrics due to the nanoparticle‐sized dendrimer (DWR), dendrimer–fluorocarbon (DWOR), and fluorocarbon (FWOR) finishing onto their surfaces. The dependence of color on the surface state of treated textiles is calculated in the context of spectrophotometric measurements. Modification of the surface roughness by reflectance spectrum and the absorbance of finishes in visible range were investigated to determine color changes between the original (control fabric, dyed but not treated) and treated fabrics. As a result of color matching calculated by CIE‐Lab values, color change is related to the surface roughness associated with absorbance values of applied finishes. In addition, fabrics mechanical properties were evaluated to estimate if finishing agents application gives rise to other changes, besides color alterations. The fabrics mechanical properties have been found not significantly altered by the aforementioned finishing treatments. These results could be applied for industrial needs (quality control), or in the artistic field of conservation, or restoration (to follow the color of paintings). © 2010 Wiley Periodicals, Inc.

Authors: Zhang Meng , Wu Yuanjuan , Zhang Qingsi , Xia Yongmei , Li Tianduo 
Published: December 2010

AbstractGelatin‐polydimethylsiloxane (PDMS) graft copolymers were prepared through the reaction between gelatin and α‐[3‐(2,3‐epoxypropoxy)propyl]‐ω‐butyl‐PDMSs. The copolymers were characterized by FTIR and 1H‐NMR spectra. As proved by wide angle X‐ray analysis, a new characteristic crystalline peak appeared after the bonding of PDMS to gelatin chains. The microstructure and the elemental identification of gelatin and copolymers were followed through scanning electron microscope with energy dispersive spectrometer. The glass transition temperature of gelatin and copolymers were obtained by differential scanning calorimetry analysis. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
The Luminescence of Sr8SrGd2 □ W4O24: Eu3+; A Case with a Low‐Lying Charge‐Transfer Transition
Authors: Blasse G. , Kemmler‐Sack S. 
Published: December 2010

AbstractThe luminescence at low temperatures of the perovskite‐like system Sr8SrGd2‐xEux□W4O24 is reported. The charge‐transfer transition of the Eu3+ ion is situated at low energy, viz. about 29000 cm−1, which influences the luminescent properties drastically. Energy transfer from the tungstate group to Eu3+ is not efficient. This transfer process occurs mainly via the C.T. state.

Mining Web search engines for query suggestion
Authors: Xu Zheng , Luo Xiangfeng , Yu Jie , Xu Weimin 
Published: December 2010

AbstractQueries to Web search engines are usually short and ambiguous, which provides insufficient information needs of users for effectively retrieving relevant Web pages. To address this problem, query suggestion is implemented by most search engines. However, existing methods do not leverage the contradiction between accuracy and computation complexity appropriately (e.g. Google's ‘Search related to’ and Yahoo's ‘Also Try’). In this paper, the recommended words are extracted from the search results of the query, which guarantees the real time of query suggestion properly. A scheme for ranking words based on semantic similarity presents a list of words as the query suggestion results, which ensures the accuracy of query suggestion. Moreover, the experimental results show that the proposed method significantly improves the quality of query suggestion over some popular Web search engines (e.g. Google and Yahoo). Finally, an offline experiment that compares the accuracy of snippets in capturing the number of words in a document is performed, which increases the confidence of the method proposed by the paper.

AbstractDifferent synthetic routes have been used for the preparation of a new tetranuclear [Fe4O2(O2CCMe3)8(bpm)] cluster (1) and a one‐dimensional coordination polymer [Fe4O2(O2CCMe3)8(hmta)]n (2) (bpm = 2,2′‐bipyrimidine and hmta = hexamethylenetetramine). For cluster 1, two structural isomers, 1a and 1b·3MeCN, have been found. X‐ray crystallographic analysis showed that all complexes consist of a central {Fe4(μ3‐O)2}8+ core. In 1a, metal ions in the core are additionally linked by six bridging pivalates as two other pivalates and a bpm ligand are chelated to FeIII ions, whereas in cluster 1b, metal ions in the {Fe4(μ3‐O)2}8+ core are linked by seven bridging pivalates and only one carboxylate as well as bpm are chelated to the iron centers. In coordination polymer 2, [Fe4O2(O2CCMe3)8] clusters are bridged by hmta ligands to form zigzag chains. Magnetic measurements have been carried out to characterize these complexes and revealed antiferromagnetic interactions between FeIII ions with best‐fit parameters of Jwb = –72.2 (1a) and –88.7 cm–1 (1b) for wing···body interactions.
Synthesis and Structural Characterization of New Bimetallic [C,N,S] Palladacycles with Mixed Bridging [P,P] and Chelating [P,P] or [P,N] Phosphane Ligands

Published: December 2010

AbstractTreatment of bimetallic palladacycles with silver perchlorate, followed by reaction with tertiary diphosphanes or diphenyl‐2‐pyridylphosphane gave novel dipalladium compounds with chelating [C,N,S], bridging [P,P], and chelating [P,P] or [P,N] ligands, as appropriate. The short‐chain diphenyl‐2‐pyridylphosphane ligand forms stable four‐membered P–N chelates, which display S–Pd–P and N–Pd–P trans geometries. The Pd–Cl bonds are nonreactive towards displacement by the [P,P] or [P,N] ligands, even in the case of strong chelating diphosphanes.

Bifunctional 2,5‐Diketopiperazines as Rigid Three‐Dimensional Scaffolds in Receptors and Peptidomimetics
Authors: Ressurreição Ana Sofia M. , Delatouche Régis , Gennari Cesare , Piarulli Umberto 
Published: December 2010

Abstract2,5‐Diketopiperazines (DKPs) are heterocyclic scaffolds easily accessible from α‐amino acids and characterized by rather flat six‐membered‐ring cores that can be functionalized at four positions (N1, N4, C3, C6), two of which are stereogenic centers (C3, C6). In this microreview, the syntheses and the solution conformations of several DKP scaffolds are discussed with regard to their application as two‐armed receptors for the selective recognition of small peptides and anions and as peptidomimetics mimicking topologically relevant elements of protein secondary structure (e.g., β‐turns, β‐hairpins, and α‐helices). In many cases the properties of these compounds can be interpreted in terms of their conformationally defined three‐dimensional structures, which can be assessed by spectroscopic and computational methods.
Room‐Temperature Columnar Liquid‐Crystalline Perylene Imido‐Diesters by a Homogeneous One‐Pot Imidification–Esterification of Perylene‐3,4,9,10‐tetracarboxylic Dianhydride
Authors: Kelber Julien , Bock Harald , Thiebaut Olivier , Grelet Eric , Langhals Heinz 
Published: December 2010

AbstractThe reaction of PTCDA (perylene‐3,4,9,10‐tetracarboxylic dianhydride) with an alcohol, a bromoalkane, and an alkylamine in the presence of DBU in DMF yields imido‐diester‐substituted perylenes. The reaction is limited to polar alcohols such as propanol, but longer alkyl chains are efficiently introduced in a second step by alkyl group exchange by using selective acidic ester hydrolysis that leaves the imide group intact. This amine‐efficient approach to imido‐diesters is used to obtain acceptor‐type self‐assembling dyes that form a hexagonal columnar liquid crystalline phase at room temperature.
