Fragment ions produced after the ionization of the acetic acid dimer (CH3COOH)(2) in a near-infrared intense femtosecond laser field were measured using time-of-flight mass spectrometry. The two-body Coulomb explosion (CE) process (CH3COOH)(2)(2+) -> 2CH(3)COOH(+) with a kinetic energy release of 3.4 eV, similar to the case of (HCOOH)(2)(2+) (Hoshina et al., 2012), was identified. The two-body CE of (CH3COOH)(2)(2+) was induced when the laser polarization direction was perpendicular to the C center dot center dot center dot C intermolecular axisin contrast to the case of (HCOOH)(2)(2+). The preferential configurations may be those that deform dimer structures close to dimer dications during the double-ionization process. (C) 2015 Elsevier B.V. All rights reserved.

ZnO is a defect-governed oxide and emits light at both visible and UV regimes. This work employs atomic layer deposition to produce oxide particles on oxygenated carbon nanotubes, and the composites only show emission profiles at short wavelengths. The quenching of defect-related emissions at long wavelengths is verified, owing to carboxyl diffusion into oxygen vacancies, and doping is supported by ZnCO3 formation in oxide lattice. Fully coated tubes display an increased photocurrent and the quantum efficiency increases by 22% relative to the bare nanotubes.

Spinal muscular atrophy (SMA) is an inherited neuromuscular disease caused by deletion or mutation of SMN1 gene. All SMA patients carry a nearly identical SMN2 gene, which produces low level of SMN protein due to mRNA exon 7 exclusion. Previously, we found that the testis of SMA mice (smn(-/-) SMN2) expresses high level of SMN2 full-length mRNA, indicating a testis-specific mechanism for SMN2 exon 7 inclusion. To elucidate the underlying mechanism, we established primary cultures of testis cells from SMA mice and analyzed them for SMN2 exon 7 splicing. We found that primary testis cells after a 2-hour culture still expressed high level of SMN2 full-length mRNA, but the level decreased after longer cultures. We then compared the protein levels of relevant splicing factors, and found that the level of Tra2-beta 1 also decreased during testis cell culture, correlated with SMN2 full-length mRNA downregulation. In addition, the testis of SMA mice expressed the highest level of Tra2-beta 1 among the many tissues examined. Furthermore, overexpression of Tra2-beta 1, but not ASF/SF2, increased SMN2 minigene exon 7 inclusion in primary testis cells and spinal cord neurons, whereas knockdown of Tra2-beta 1 decreased SMN2 exon 7 inclusion in primary testis cells of SMA mice. Therefore, our results indicate that high expression level of Tra2-beta 1 is responsible for increased SMN2 exon 7 inclusion in the testis of SMA mice. This study also suggests that the expression level of Tra2-beta 1 may be a modifying factor of SMA disease and a potential target for SMA treatment.

We have studied hydrogen-atom tunneling in the cis-to-trans conformational change of some carboxylic acid monomers and formic acid (FA) complexes and dimers at the MP2(full) and CCSD(T) levels of theory within the Wentzel-Kramers-Brillouin approximation. The barrier for the minimum energy path, where the OH bond length and the COH bending angle are optimized, is found to be a good approximation for providing the highest barrier transparency. The matrix effect on the transmission coefficients of cis-FA monomer, trans-cis FA dimer (tc1), and cis-acetic acid monomer are modeled by the polarizable continuum model (PCM) at the MP2(full) level of theory in different environments. For the cis-FA monomer and trans-cis FA dimer (tc1), the calculated transmission coefficients agree with the experimental lifetimes observed in noble-gas solids. However, this method cannot reproduce the experimental results obtained for cis-acetic acid. Moreover, the long lifetime of cis-FA and cis-acetic acid in the N-2 environment cannot be reproduced either, which is most probably due to specific interactions that are not included in the PCM. The calculation for cis-HCOOD shows a strong decrease of the barrier transparency compared to that for cis-HCOOH, which is consistent with the experiments. In general, good agreement is observed between the calculated barrier transparency (including PCM) and experimental tunneling rate. However, some exceptions are found, which shows that additional factors influence the tunneling rate.

Proton-bound rare-gas dimer (RgHRg)(+), in which Rg represents a rare-gas atom, serves as a prototypical system for proton solvation by inert-gas atoms. Until now, only centrosymmetric species with Rg = Ar, Kr, or Xe have been identified with infrared spectra. We employed electron bombardment during deposition of a mixture of Xe (or Kr) in p-H-2 at 3.2 K to prepare (RgHRg)(+). Lines at 847.0 and 972.1 cm(-1) are assigned as the Rg-H-Rg antisymmetric stretching (nu(3)) mode and its combination with the RgHRg symmetric stretching (nu(1) + nu(3)) mode of (XeHXe)(+) in solid p-H-2, respectively. Lines at 871.1 and 974.0 cm(-1) are assigned as the nu(3) and nu(1) + nu(3) modes of (KrHKr)(+) in solid p-H-2, respectively. Slightly shifted and broadened lines were observed for these species in solid n-H-2. These results agree satisfactorily with reported experimental values of (XeHXe)(+) and (KrHKr)(+) in solid Xe, Kr, and Ar, and with the quantum-chemically predicted anharmonic vibrational wavenumbers of these species in the gaseous phase; the significant spectral shifts in various matrixes are rationalized with the proton affinities of the hosts. When a mixture of Xe and Kr in p-H-2 was used, an additional broad feature at 1284 cm(-1) was observed and assigned as the nu(3) mode of (KrHXe)(+) in solid p-H-2. This line shifted to 1280 cm(-1) in solid n-H-2 and the corresponding line of (KrDXe)(+) was observed at 954 cm(-1) in n-D-2. The observations of these lines are new; the wavenumbers significantly blue shifted from those of the centrosymmetric (RgHRg)(+) agree with the quantum-chemically predicted anharmonic vibrational wavenumbers of 1279 cm(-1) for (KrHXe)(+) and 916 cm(-1) for (KrDXe)(+). Analysis of the computational results shows that electronic correlation effects play a much greater role for the asymmetric than for the symmetric species. An interpretation for this is provided.

A method for treating wastewater containing TMAH and ammonium nitrogen includes the steps of (a) introducing a first solution which contains ammonium nitrogen but no TMAH into a single reactor with microorganisms comprising nitrifying bacteria and anammox bacteria, and denitrifying the first solution by the microorganisms under a dissolved oxygen concentration ranging from 0.1-0.5 mg/L and a pH value of 7-8; (b) when the denitrification efficiency reaches a steady state, introducing a second solution which contains ammonium nitrogen and TMAH and has a concentration of TMAH lower than 60 mg/L into the reactor; and (c) gradually increasing the concentration of TMAH in the solution to be added into the reactor for several times whenever the denitrification efficiency reaches a steady state. Accordingly, the inhibition of TMAH to the anammox bacteria can be significantly decreased, and both TMAH and the ammonium nitrogen can be treated simultaneously.

Mechanically encoded single-photon sources: Stress-controlled excitonic fine structures of droplet epitaxial quantum dots

We present numerical investigations based on the Luttinger-Kohn four-band k . p theory and, accordingly, establish a quantitatively valid model of the excitonic fine structures of droplet epitaxial GaAs/AlGaAs quantum dots under uniaxial stress control. In the formalisms, stressing a photoexcited quantum dot is equivalent creating a pseudomagnetic field that is directly coupled to the pseudospin of the exciton doublet and tunable to tailor the polarized fine structure of exciton. The latter feature is associated with the valence-band mixing of exciton, which is especially sensitive to external stress in inherently unstrained droplet epitaxial GaAs/AlGaAs quantum dots and allows us to mechanically design and prepare any desired exciton states of QD photon sources prior to the photon generation.
