Bis(imino)aryl NCN pincer cobalt complexes: synthesis and disproportionation.

Treatment of iPr[NCN]Br (2,6-(2,6-iPr2C6H3C[double bond, length as m-dash]N)2C6H3Br) with nBuLi in THF and the subsequent addition of 1 equiv. of CoCl2, CoCl2(Ph3P)2, and CoBr2 gave pincer Co(ii) complexes {iPr[NCN]Co(μ-Cl)}2 (1d), iPr[NCN]CoClPh3P (1d-Ph3P), and iPr[NCN]CoBr2·Li(THF)4 (1d-LiBr) respectively in moderate yields, whereas the slow addition of in situ prepared iPr[NCN]Li to CoCl2 in THF afforded an unexpected mixed-valence cobalt(i/ii) complex κ2C,N,η6-iPr[NCN]Co-κN-CoCl3·Li(THF)4 (2d). Complex 2d was probably formed via a disproportionation reaction of the iPr[NCN]Co(ii) species with excess CoCl2 during the reaction.

Influence of product volume on water antimicrobial efficacy and cross-contamination during retail batch washing of lettuce.

Fresh produce shall be thoroughly washed at the retail level prior to serving to the consumer with potable water. Foodborne pathogens if present on a product may transfer to the wash water and cross-contaminate other products immersed in the water. Typically, an entire carton of lettuce (24 heads) is washed together increasing the likelihood of cross-contamination due to the close contact between each head.

A nanostructured MoO/MoS/MoP heterojunction electrocatalyst for the hydrogen evolution reaction.

Electrocatalytic production of hydrogen from water is considered to be a promising and sustainable strategy. In this work, the low-cost nanostructured MoO/MoS/MoP heterojunction is successfully synthesized by phosphorization of the pre-prepared urchin-like MoO/MoS nanospheres as the stable, highly efficient electrocatalysis for the hydrogen evolution reaction (HER). The MoO/MoS/MoP-800 (MoO/MoS nanospheres are phosphated at 800 °C) displays a catalytic ability for the HER with an overpotential of 135 mV to achieve 10 mA cm and a Tafel slope of 67 mV dec in 0.

Seasonal and spatial distributions of euphotic zone and long-term variations in water transparency in a clear oligotrophic Lake Fuxian, China.

To assess the seasonal and spatial variations and long-term trends in water optical properties in Lake Fuxian, investigations based on field work in four seasons and a long-term analysis of data from 1980 to 2014 were conducted. The results show that there was no significant variation in the euphotic depth (Z) across the four seasons, and no significant correlations between Z and potential influencing factors in seasons other than summer, suggesting that the water itself may be a major factor regulating the Z in general. Nevertheless, significant differences in Z between the north region (NR) and the south region (SR) were observed in all seasonal tests except spring.

Isolation and characterization of a highly pathogenic strain of Porcine enteric alphacoronavirus causing watery diarrhoea and high mortality in newborn piglets.

Porcine enteric alphacoronavirus (PEAV) was first discovered in China in February 2017, and the origin and virulence of this novel porcine coronavirus were not fully characterized. Here, we isolated a strain of PEAV, named GDS04 that is identified by immunofluorescence and typical crown-shaped particles observed with electron microscopy. Genomic analysis reveals that PEAV GDS04 shares a close relationship with SADS-CoV and SeACoV.

A flagellin-adjuvanted PED subunit vaccine improved protective efficiency against PEDV variant challenge in pigs.

PEDV variants, causing severe diarrhea in neonatal suckling piglets with a mortality rate up to 100%, have being epidemic since late 2010 in china. To meet the pressing need of safe and cost-efficient PED maternal vaccines against PEDV variant, we vaccinated growing piglets with a flagellin-adjuvanted PED vaccine rSF-COE-3D by injection at Houhai acupoint. The vaccination not only enhanced the antibody responses of serum IgG/IgA, mucosal IgA and serum neutralizing antibody, but also improved the production of IFN-γ and IL-4.

PED subunit vaccine based on COE domain replacement of flagellin domain D3 improved specific humoral and mucosal immunity in mice.

Porcine epidemic diarrhea (PED) is an important re-emergent infectious disease and inflicts huge economic losses to the swine industry worldwide. To meet the pressing need of developing a safe and cost-efficient PED maternal vaccine, we generated three PED subunit vaccine candidates, using recombined Salmonella flagellin (rSF) as a mucosal molecular adjuvant. Domain D3 in rSF was replaced with COE domain of PEDV to generate rSF-COE-3D.

Combining hydrogen peroxide addition with sunlight regulation to control algal blooms.

The concentration, light conditions during treatment, and the number of hydrogen peroxide (HO) additions as well as the HO treatment combined with subsequent shading to control algal blooms were studied in the field (Lake Dianchi, China). The cyanobacterial stress and injury due to HO were dose dependent, and the control effectiveness and degradation of HO were better and faster under full light than under shading. However, HO was only able to control a bloom for a short time, so it may have promoted the recovery of algae and allowed the biomass to rebound due to the growth of eukaryotic algae.
