AbstractWireless local area networks are an increasing alternative to wired data networks in workplaces, homes, and public areas. Concerns about possible health effects of this type of signal, especially when exposure occurs early in life, have been raised. We examined the effects of prenatal (in utero) exposure to wireless fidelity (WiFi) signal‐associated electromagnetic fields (2450 MHz center‐frequency band) on T cell development and function. Pregnant mice were exposed whole body to a specific absorption rate of 4 W/kg, 2 h per day, starting 5 days after mating and ending 1 day before the expected delivery. Sham‐exposed and cage control groups were used as controls. No effects on cell count, phenotype, and proliferation of thymocytes were observed. Also, spleen cell count, CD4/CD8 cell frequencies, T cell proliferation, and cytokine production were not affected by the exposure. These findings were consistently observed in the male and female offspring at early (5 weeks of age) and late (26 weeks of age) time points. Nevertheless, the expected differences associated with aging and/or gender were confirmed. In conclusion, our results do not support the hypothesis that the exposure to WiFi signals during prenatal life results in detrimental effects on the immune T cell compartment.

Serial assembly of Thermus megaplasmid DNA in the genome of Bacillus subtilis 168: A BAC‐based domino method applied to DNA with a high GC content
Authors: Ohtani Naoto , Hasegawa Miki , Sato Mitsuru , Tomita Masaru , Kaneko Shinya , Itaya Mitsuhiro 
Published: May 2012

AbstractBacillus subtilis is the only bacterium‐based host able to clone giant DNA above 1000 kbp. DNA previously handled by this host was limited to that with GC content similar to or lower than that of the B. subtilis genome. To expand the target DNA range to higher GC content, we tried to clone a pTT27 megaplasmid (257 kbp, 69% of G+C) from Thermus thermophilus. To facilitate the reconstruction process, we subcloned pTT27 in a bacterial artificial chromosome (BAC) vector of Escherichia coli. Owing to the ability of BAC to carry around 100 kbp DNA, only 4 clones were needed to cover the pTT27 and conduct step‐by‐step assembly in the B. subtilis genome. The full length of 257 kbp was reconstructed through 3 intermediary lengths (108, 153, and 226 kbp), despite an unexpected difficulty in the maintenance of DNA >200 kbp. Retrieval of these four pTT27 segments from the B. subtilis genome by genetic transfer to a plasmid pLS20 was attempted. A stable plasmid clone was obtained only for the 108 and 153 kbp intermediates. The B. subtilis genome was demonstrated to accommodate large DNA with a high GC content, but may be restricted to less than 200 kbp by unidentified mechanisms.
Process Intensification by Membrane Reactors: High‐Temperature Water Gas Shift Reaction as Single Stage for Syngas Upgrading
Authors: Brunetti A. , Caravella A. , Drioli E. , Barbieri G. 
Published: May 2012

AbstractPd‐based membrane reactors (MRs) selectively removing hydrogen shift the equilibrium conversion of this new reactor type to values higher than those imposed by thermodynamics to traditional reactors. Thus, the equilibrium conversion of CO is significantly increased and can be very strongly depending on the hydrogen extracted also at a higher temperature. This property of the MRs offers important benefits also in terms of process intensification. In the typical high‐temperature range for this reaction, i.e., 300–450 °C, the performance of an MR turned out to be so effective that the two reactors of a traditional process can be replaced by one MR of lower volume, too. The conversion of the MR is higher than the one of the whole traditional process which includes a heat exchanger in addition to two reactors. Consequently, less and smaller unit operations are required when an MR operates the water gas shift reaction pursuing the process intensification philosophy.
A Microplasma Reactor for Chemical Process Intensification
Authors: Lindner P. J. , Besser R. S. 
Published: May 2012

AbstractA novel approach to chemical process intensification based on microplasma reactor systems is presented. Microplasmas (plasmas generated in sub‐mm volumes) possess a favorable reaction environment because of high densities of reactive ions, radicals, and electrons. Moreover, operation under atmospheric pressure and near‐room temperature makes them convenient for implementation. Experiments utilized a microfabricated microplasma reactor to intensify the reforming of methanol into a hydrogen‐rich product stream useful for energy applications such as combustion or fuel cells. A reaction model elaborates the key mechanisms and demonstrates that reaction rates in the microplasma environment surpass those of conventional plasma reactors. The outcome is that microplasma chemical processing is a viable approach for hydrocarbon reforming and merits consideration for other chemical reaction applications.
Photoinduced Energy and Electron Transfer in Phenylethynyl‐Bridged Zinc Porphyrin–Oligothienylenevinylene–C60 Ensembles
Authors: Urbani Maxence , Ohkubo Kei , Islam D. M. Shafiqul , Fukuzumi Shunichi , Langa Fernando 
Published: May 2012

AbstractDonor–bridge–acceptor triad (Por‐2TV‐C60) and tetrad molecules ((Por)2‐2TV‐C60), which incorporated C60 and one or two porphyrin molecules that were covalently linked through a phenylethynyl‐oligothienylenevinylene bridge, were synthesized. Their photodynamics were investigated by fluorescence measurements, and by femto‐ and nanosecond laser flash photolysis. First, photoinduced energy transfer from the porphyrin to the C60 moiety occurred rather than electron transfer, followed by electron transfer from the oligothienylenevinylene to the singlet excited state of the C60 moiety to produce the radical cation of oligothienylenevinylene and the radical anion of C60. Then, back‐electron transfer occurred to afford the triplet excited state of the oligothienylenevinylene moiety rather than the ground state. Thus, the porphyrin units in (Por)‐2TV‐C60 and (Por)2‐2TV‐C60 acted as efficient photosensitizers for the charge separation between oligothienylenevinylene and C60.
Surface‐Plasmon‐Enhanced Band Emission of ZnO Nanoflowers Decorated with Au Nanoparticles
Authors: Kochuveedu Saji Thomas , Oh Ji Hye , Do Young Rag , Kim Dong Ha 
Published: May 2012

AbstractA simple strategy was used to enhance band emission through the transfer of defect emission from ZnO to Au by using the energy match between the defect emission of ZnO and the surface plasmon absorbance of Au NPs through decorating the surface of ZnO nanoflowers with Au nanoparticles (Au NPs). The ZnO nanostructure, which was comprised of six nanorods that were attached on one side in a flower‐like fashion, was synthesized by using a hydrothermal method. The temperature‐dependent morphology and detailed growth mechanism were studied. The influence of the density of the Au NPs that were deposited onto the surface of ZnO on photoluminescence was investigated to optimize the configuration of the ZnO/Au system in terms of the maximum band emission. The sequential transfer of defect energy from ZnO to Au and electron transfer from excited Au to ZnO was proposed as a possible mechanism for the enhanced band emission.
