Localized application of soil organic matter shifts distribution of cluster r…
Background and Aims Phosphorus (P) is a major factor controlling cluster-root formation. Cluster-root proliferation tends to concentrate in organic matter (OM)-rich surface-soil layers, but the nature of this response of cluster-root formation to OM is not clear. Cluster-root proliferation in response to localized application of OM was characterized in Lupinus albus (white lupin) grown in strat…

TRANSESTERIFICATION OF DIMETHYL OXALATE WITH PHENOL OVER Ti-CONTAINING PHOSPH…
Abstract The transesterification of dimethyl oxalate (DMO) with phenol is studied on various Ti-containing phosphate (Ti-P-O) catalysts. The weak acid-base characteristics of Ti-P-O catalysts are responsible for the high activity and selectivity to methyl phenyl oxalate (MPO) and diphenyl oxalate (DPO). Keywords: Transesterification, dimethyl oxalate, methylphenyl oxalate, diphenyl oxalate

One-step synthesis of H–B zeolite-enwrapped Co/Al2O3 Fischer–Tropsch cata…
Abstract. A tailor-made encapsulated catalyst with a H–B zeolite shell has been directly synthesized over Co/Al2O3 pellets to form a core–shell structure without pinholes and cracks by a hydrothermal synthesis method. Pretreatment of the Co/Al2O3 pellets with reflux of hot TEAOH solution can clean and corrode the pellet surface due to its strong basicity, and can enlarge the mean pore s…

Photodegradation of SF6 on polyisoprene surface: Implication on elimination o…
Abstract. Photodegradation of SF6 was performed on the surface of polyisoprene (PI) based on a brand new mechanism of “controlled release of radicals”. Effective decomposition of SF6 (60% of SF6 was degraded in 4 h) was achieved due to the highly reductive radicals (mainly allylic radicals and excited C C bond) which were generated from the photolysis of PI. No toxic fluoride was detect…

Drastically enhanced photocatalytic activity in nitrogen doped mesoporous TiO…
Abstract. Nitrogen doped mesoporous TiO2 was prepared via a modified two-step hydrothermal route. In contrast to undoped mesoporous TiO2, nitrogen doped mesoporous TiO2 has superior photocatalytic activity under both UV and visible light irradiation. Photoluminescence spectra reveal that nitrogen doped mesoporous TiO2 possesses abundant surface states, which can play a vital role in trappin…

The role of crystal phase in determining photocatalytic activity of nitrogen …
Abstract. Two series of nitrogen doped TiO2 samples with different ratios of anatase to rutile phases were prepared by milling the mixture of P25 TiO2 and C6H12N4 in air and gaseous NH3 atmosphere, respectively. Compared to air, NH3 atmosphere plays an important role in delaying the crystallite transformation from anatase to rutile in the mechanochemical reaction of TiO2 and C6H12N4. In con…

One-step synthesis of nanostructured Pd-doped mixed oxides MOx-CeO2 (M = Mn, …
Abstract. A series of nanostructured Pd-doped mixed oxides MOx-CeO2 (M = Mn, Fe, Co, Ni, Cu), with uniform mesoporous structure and large surface area exceeding 115 m2 g-1, were synthesized in one step by a surfactant-assisted co-precipitation. Their catalytic performance was investigated using total oxidation of CO and C3H8 as the model reactions. The results show that, a synergism exists…

The Nanomorphology-Controlled Palladium-Support Interaction and the Catalytic…
Abstract Nanorods and nanoparticles of CeO2 were successfully synthesized and used as support of Pd/CeO2 catalysts. It is found that the nanorods show obvious advantages as the support, compared with the nanoparticles. Low efficiency in the formation of reduced Pd, and partial encapsulation of Pd species account for the poor activity of Pd supported on CeO2 nanoparticles. On the contrary, a …

Long wavelength emissions of periodic yard-glass shaped boron nitride nanotubes
Extraordinary and stable long wavelength emission centered at 685 nm from the yard-glass shaped boron nitride nanotubes YG-BNNTs was observed in their cathodoluminescence and photoluminescence spectroscopy. The mechanism for this near-red light emission at 685 nm is attributed to the periodical nature of the BNNT units with regular lattice defects. The visible-light emission from YG-B…

Estimating The Incidences Of The Recent Pension Reform In China: Evidence Fro…
An ongoing reform in China mandates employers to contribute significant amounts to employee pension funds. The current study estimates the impact of this reform on the wage, employment, and performance of firms using data from over 140,000 medium and large manufacturers in China during 2004 and 2006. We find that the nominal wages of employees were rigid, but their real wages may have declined …

Biomass Suspension Combustion: Effect of Two-Stage Combustion on NOx Emission…
A systematic study was performed in a suspension fired 20 kW laboratory-scale swirl burner test rig for combustion of biomass and co-combustion of natural gas and biomass. The main focus is put on the effect of two-stage combustion on the NO emission, as well as its effect on the incomplete combustion. When twostage combustion was applied, the NO emission level can be significantly reduced. …

Glycine betaine (GB) can enhance heat tolerance and the accumulation of heat-shock protein (HSP) in plants, but the effects of GB on HSP accumulation during salt stress were not previously known. To investigate the mechanism of how GB influences the expression of HSP, wild-type tobacco (Nicotiana tabacum) seedlings pretreated with exogenous GB and BADH-transgenic tobacco plants that accumu…
