Universal Colorimetric Detection of Nucleic Acids Based on Polydiacetylene (PDA) Liposomes
Authors: Jung Yun Kyung , Kim Tae Won , Kim Jumi , Kim Jong‐Man , Park Hyun Gyu 
Published: March 2008

AbstractA universal colorimetric method for the detection of nucleic acids, based on ionic interactions by polydiacetylene (PDA) liposomes, is described. Primary and quaternary amine‐modified diacetylene monomers were synthesized and used to generate positively charged PDA liposomes. The resulting PDA sensors showed a dramatic color change from blue to red upon the addition of nucleic acids amplified by using the polymerase chain reaction (PCR) due to the stimuli caused by ionic interactions between the positively charged PDA and negatively charged phosphate backbone of the nucleic acids. The color change that takes place can be simply detected by the naked eye. Compared with quaternary amine‐functionalized PDA vesicles, the primary amine‐functionalized PDA underwent a more intense color transition under optimized conditions. By using the PDA‐based colorimetric sensor, nucleic acids amplified by common PCR reaction, whose typical concentration is around 100 nM, can be readily detected. Since implementation of this universal colorimetric method is simple, rapid and does not require any sophisticated instrumentation, it should have greatly enhanced applications as a technology for DNA diagnosis.
Synthesis of Rhodium Colloidal Nano‐Coating Grafted Mesoporous Silica Composite and its Application as Efficient Environmentally Benign Catalyst for Heck‐Type Reaction of Arylboronic Acids
Authors: Li Liang , Shi Jianlin 
Published: March 2008

AbstractThe synthesis and characterization of rhodium colloidal layer grafted mesoporous SBA‐15 material, designated as SBA‐Rh, are presented. In the preparation of this new catalyst, SBA‐15 mesoporous material was used as support without any pretreatment. The SiH functional groups were introduced onto the surface which resulted in highly dispersed metal colloid layer both on the outer and inner surface of the supporting material. The material was investigated for Heck‐type coupling reactions of alkenes with ayboronic in organic/water solvent. The ultrahigh specific area, large pore opening, and highly dispersed catalyst species in SBA‐Rh material created one of the most active heterogeneous catalysts for such reactions. Rhodium element was not detected in the final mixture by ICP after reaction. The catalyst species showed very high stability against leaching from the matrix and can be recycled for repeated use.
Mechanistic study on dimerization of acetylene with a Nieuwland catalyst
Authors: Tachiyama Takashi , Yoshida Makoto , Aoyagi Tatsuhiro , Fukuzumi Shunichi 
Published: March 2008

AbstractA mechanistic study on the Nieuwland catalysis for dimerization of acetylene is performed by detecting copper–acetylene and copper–monovinylacetylene π‐complexes and also by examining the kinetics under virtually the same reaction conditions employed in the industrial process. An efficient H/D exchange occurs between acetylene and protons in the Nieuwland catalytic system. Addition of a coordinating ligand to the conventional Nieuwland catalytic system results in improvement of the catalytic activity and selectivity for the acetylene dimerization. The kinetic analysis including the kinetic deuterium isotope effect provides valuable insight into the Nieuwland catalytic mechanism of the dimerization of acetylene.

AbstractTwo water‐soluble palladium (II) complexes 2 and 4 have been synthesized from easily available 2‐arylnaphthoxazole derivatives. They were successfully applied to the Suzuki coupling of aryl bromides with phenylboronic acid in water at 100 °C under phosphine‐free conditions. Copyright © 2008 John Wiley & Sons, Ltd.
Damping characteristics of chlorobutyl rubber/poly(ethyl acrylate)/piezoelectric ceramic/carbon black composites
Authors: Liu Zhiyuan , Wang Yanyan , Huang Guangsu , Wu Jinrong 
Published: March 2008

AbstractIn this study, a new kind of damping composite consisting of chlorobutyl rubber, poly(ethyl acrylate), piezoelectric ceramic (PZT), and carbon black (CB) was prepared, and some efforts were made to characterize the damping behavior and explore the damping mechanism. The damping behaviors of the composites were mainly decided by the contents of CB and PZT. When an external vibration was exerted on the composites, the mechanical energy of vibration was transformed into electric energy by PZT; if the resistance was adjusted to a suitable range by the variation of the CB content, the composites could behave as semiconductors: the electric energy could not be transferred to the surface of the material but rather was dissipated as thermal energy. For this system, when the contents of CB and PZT were between 10 and 30 vol %, respectively, the volume resistivity was between 105 and 109.5 Ω cm, and a good damping performance could be achieved. On the basis of the results, a theoretical model is proposed to explain the damping performance of the composites. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Moisture‐cured polyurethane/polysiloxane copolymers: Effects of the structure of polyester diol and NCO/OH ratio
Authors: Jiang Hongmei , Zheng Zhen , Song Wenhui , Wang Xinling 
Published: March 2008

AbstractMoisture‐cured polyurethane is one of the commercially important polymers, which is widely used in sealants, coatings, and reactive hot‐melt adhesives. A series of moisture‐cured polyurethane/polysiloxane (PUSR) copolymers were successfully prepared using a two‐step solution polymerization procedure. Both amine‐terminated polysiloxane (PDMS) and polyester diol were together used as mixed soft segments to react with 4,4′‐diphenlymethane diisocyanate (MDI), and the alkoxysilane was used as end‐capping agents. The effects of structure variation of building blocks such as the polyester diol structure and NCO/OH ratio on the properties and morphology of PUSR copolymers were studied. The tensile properties, dielectric behavior, thermal stability, surface, and water‐repellency properties were investigated. The results showed that the properties and morphology of PUSR copolymers were greatly affected by the variations in molecular architecture. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Children with autism demonstrate circumscribed attention during passive viewing of complex social and nonsocial picture arrays
Authors: Sasson Noah J. , Turner‐Brown Lauren M. , Holtzclaw Tia N. , Lam Kristen S.L. , Bodfish James W. 
Published: March 2008

AbstractAlthough circumscribed interests are a hallmark characteristic of autism spectrum disorders, providing a means for quantifying their functional impairment has proven difficult. We developed a passive viewing task to measure aspects of visual attention in children with autism spectrum disorders and typically developing controls. Task stimuli included picture arrays that were matched for social and nonsocial content. Nonsocial content was balanced to include items related to circumscribed interests (e.g., trains) as well as more commonplace items (e.g., furniture). Discrete aspects of gaze behavior were quantified using eye‐tracking technology. Results indicate that visual attention in the autism group was more circumscribed (as indicated by the exploration of fewer images), more perseverative (as indicated by longer fixation times per image explored), and more detail oriented (as indicated by a greater number of discrete fixations on explored images). This pattern of results was similar for both social and object arrays. Within the autism group, overall severity of repetitive behavior symptoms correlated positively with exploration of object pictures and negatively with perseveration on social pictures. Results suggest that children with autism have a domain‐general pattern of atypical visual attention that may represent an exaggeration of a typical attentional process and is related to a tendency to perseverate on images of interest and explore them in a more detail‐oriented manner. Discrete measures of visual attention may therefore provide a reasonable means of quantifying aspects of the repetitive behavior phenotype in autism.
Face and object processing in autism spectrum disorders
Authors: Wallace Simon , Coleman Michael , Bailey Anthony 
Published: March 2008

AbstractThe nature and extent of face‐processing impairments in individuals with autism spectrum disorder (ASD) remain contentious. The aim of this research study is to assess the face‐ and object‐processing performance of individuals with ASD compared with typically developing controls. Our hypothesis was that individuals with ASD would be significantly impaired on tests of face processing but show intact object processing. More specifically, we tested two competing hypotheses to explain face‐processing deficits: holistic hypothesis; second‐order configural hypothesis. Twenty‐six able adults with ASD and 26 intelligence quotient‐matched typically developing controls completed two computerized tests of face and object discrimination. In task 1, the first picture (faces or cars) in a pair was presented as quickly as 40 msec to test holistic processing. In task 2, the decision was whether pairs of faces or houses had been altered in terms of the features or the distance between the features (the second‐order configural properties). Individuals with ASD were impaired on all tests of face processing but showed intact object processing and the pattern of findings favored the holistic hypothesis. The heterogeneous pattern of performance in the clinical group showed that some individuals with ASD perform similarly to typically developing individuals in their face‐processing skills, whereas others are more accurate in object processing compared with face processing.
