Visible light irradiation enhanced sulfidated zero-valent iron/peroxymonosulfate process for organic pollutant degradation.

This study developed a novel process named sulfidated zero-valent iron/peroxymonosulfate/visible light irradiation (S-mZVI/PMS/vis) for enhanced organic pollutant degradation. The S-mZVI/PMS/vis process exhibited remarkable catalytic activity, achieving a 99.6% rhodamine B (RhB) removal within 10 min.

Low-cost eggshell-fly ash adsorbent for phosphate recovery: A potential slow-release phosphate fertilizer.

Fly ash (FA) and eggshells (ES) are common solid wastes with significant potential for the recovery of phosphorus from water. This study focuses on synthesizing a low-cost and environmental-friendly phosphate adsorbent called eggshell-fly ash geopolymer composite (EFG) using eggshells instead of chemicals. The CaO obtained from the high-temperature pyrolysis of eggshells provides active sites for phosphate adsorption, and CO serves as a pore-forming agent.

Generation of High-Quality African Swine Fever Virus Complete Genome from Field Samples by Next-Generation Sequencing.

African swine fever (ASF) is a lethal contagious viral disease of domestic pigs and wild boars caused by the African swine fever virus (ASFV). The pandemic spread of ASF has caused severe effects on the global pig industry. Whole-genome sequencing provides crucial information for virus strain characterization, epidemiology analysis and vaccine development.

Synergistic effect and mechanism of Cd(II) and As(III) adsorption by biochar supported sulfide nanoscale zero-valent iron.

Biochar derived from bamboo was used to support sulfide nanoscale zero-valent iron (S-nZVI@BC) for simultaneous removal of Cd(II) and As (III) from aqueous media. Scanning electron microscopy (SEM) and X-ray diffraction spectroscopy (XRD) characterization confirmed the successful synthesis of the S-nZVI@BC. Adsorption kinetics and isotherms indicated that co-adsorption of Cd(II) and As(III) onto S-nZVI@BC was well represented by pseudo-second-order model (R = 0.

Peroxymonosulfate activation by graphene oxide-supported 3D-MoS/FeCoO sponge for highly efficient organic pollutants degradation.

To address conventional powder catalysts' recovery and aggregation issues that greatly restrain their practical application, a recoverable graphene oxide (GO)-supported 3D-MoS/FeCoO sponge (SFCMG) was developed through a simple impregnation pyrolysis method. SFCMG can efficiently activate peroxymonosulfate (PMS) to produce reactive species for rapid degradation of rhodamine B (RhB), with 95.0% and 100% of RhB being removed within 2 min and 10 min, respectively.

Eggshell based biochar for highly efficient adsorption and recovery of phosphorus from aqueous solution: Kinetics, mechanism and potential as phosphorus fertilizer.

Development of an efficient and green adsorbent is of great significance for phosphorus removal and recovery from eutrophic water. This work prepared an eggshell modified biochar (ESBC) by co-pyrolysis of eggshells and corn stalk. ESBC exhibited an excellent performance for phosphorus adsorption over a wide pH range (5-13), and achieved a maximum adsorption of 557.

Clinical Validation of Two Recombinase-Based Isothermal Amplification Assays (RPA/RAA) for the Rapid Detection of African Swine Fever Virus.

African swine fever (ASF), caused by African swine fever virus (ASFV), is a devastating infectious disease of domestic pigs and wild boars, and has tremendous negative socioeconomic impact on the swine industry and food security worldwide. It is characterized as a notifiable disease by World Organisation for Animal Health (OIE). No effective vaccine or treatment against ASF has so far been available.

Infection of African swine fever in wild boar, China, 2018.

On 16 November 2018, a wild boar infected with African swine fever was reported in China. The phylogenetic analysis showed that its causative strain belonged to the p72 genotype II, CD2v serogroup 8 and contained no additional tandem repeat sequences between the I73R and the I329L protein genes, which was different from previously reported strains in China.

Rescue of eGFP-expressing small ruminant morbillivirus for identifying susceptibilities of eight mammalian cell lines to its infection.

Small ruminant morbillivirus (SRMV), formerly called peste-des-petits-ruminants virus (PPRV), is classified into the genus Morbillivirus in the family Paramyxoviridae. If genetically modified using reverse genetics, the SRMV would be a useful vector to express foreign proteins in vitro and in vivo. In this study, a recombinant SRMV was rescued by reverse genetics for efficiently expressing an enhanced green fluorescent protein (eGFP) in vitro.

Development of reverse genetics system for small ruminant morbillivirus: Rescuing recombinant virus to express Echinococcus granulosus EG95 antigen.

Peste des petits ruminants and cystic hydatidosis may be simultaneously endemic in a given area. Their pathogens are small ruminant morbillivirus (SRMV) and Echinococcus granulosus (E. granulosus), respectively.

Development of real-time reverse transcription recombinase polymerase amplification (RPA) for rapid detection of peste des petits ruminants virus in clinical samples and its comparison with real-time PCR test.

Peste des petits ruminants (PPR), caused by small ruminant morbillivirus (SRMV), formerly called peste des petits ruminants virus (PPRV), is one of the most important pathogens in small ruminants, and has tremendous negative economic impact on the sheep industry worldwide. Current detection of PPRV in clinical samples mainly relies on real-time RT-PCR. Particularly, samples collected from rural area require highly equipped laboratories for screening.

Allelic variants of PRNP in 16 Chinese local sheep breeds.

Here, polymorphisms of the ovine prion protein gene were analyzed in 486 Chinese sheep from 16 main local breeds. Polymorphisms R or H at codons 154 and four polymorphisms at codon 171 encoding Q, R, H, or K were identified. The A/V polymorphism at codon 136 was not observed, and all sheep were homozygous for A at this position.
