Significant Progress on the Development of Covalent Organic Frameworks-Based Solid-Phase Microextraction Probe
Rapid, sensitive, and accurate analysis of trace environmental pollutants is urgently required in the field of environmental analytical chemistry. Per- and polyfluoroalkyl substances (PFASs) are a series of persistent organic pollutants (POPs) widespread in environment and organism, and they have been concerned widely by both health authorities and public due to their hepatotoxicity, reproductive toxicity, and potential carcinogenicity. Perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) are the two most widely used PFASs that have been designated as target chemicals for regulation by the Stockholm Convention on POPs. It is necessary to monitor the contents and compositions of PFASs in environmental and biological media for understanding their environmental behaviors and toxic effects.
Multidrug‐Resistant Proteus mirabilis isolates carrying blaOXA‐1 and blaNDM‐1 from wildlife in China
Microbial pathogen ecology research Group from the Wildlife Diseases and Immunology Research Center, Institute of zoology, Guangdong Academy of Sciences, conducted research on Proteus mirabilis isolated from wild animals from Shanghai Zoo, hospital, Zhengzhou zoo and illegal trafficking, and found that wild animals carried important multidrug-resistant genes blaOXA-1 and blaNDM-1. On December 2, 2020, the research results were published in integrative zoology (https://onlinelibrary.wiley.com/doi/epdf/10.1111/1749-4877.12510).
Material reinforced mechanism and industrial applications of a novel selective laser melted precipitation hardening stainless steel (SLM CX PHSS)
Due to the unique characteristics of good corrosion resistance, high hardness and strength, good toughness, and excellent formability, precipitation hardening stainless steel (PHSS) has become a top candidate for advanced industrial applications such as aerospace, shipbuilding, automotive, high-end tools and biomedical applications.
VV reduction by Polaromonas spp. in vanadium mine tailings
The Weimin Sun research group has recently published an article entitled “VV reduction by Polaromonas spp. in vanadium mine tailings” in the prestigious journal “Environmental Science & Technology”. The study provided an in depth investigation of the microbial responses to elevated vanadium concentration using a combination of the field survey, lab experiments, and bioinformatic analysis.
GIIM: Model-driven Lightweight Neural Network for Robot Force Control in Dynamic Complex Environment
Robot is known as "the pearl at the top of the crown of the manufacturing industry", and serves as an important supporting tool of intelligent manufacturing.
New progress in photo-reforming of biomass into hydrogen at Guangdong Institute of Analysis
Stringent measures on the use of fossil fuels have led to the rapid development of alternative renewable energy sources. In particular, hydrogen has been identified as promising renewable energy. However, conventional hydrogen production methods suffer from high energy consumption and high dioxide emissions.
Research unveiled the community assembly mechanisms of birds in the Nanling Mountain
Mixed-species bird flocks (MSF) are defined as “groups of two or more species that move and forage together”. MSFs are widely acknowledged to increase predator avoidance and foraging efficiency, and thereby increase participants’ fitness, which were often used to investigate community structure of birds. The mechanisms of community assembly suggest that biotic and abiotic filters constrain species establishment through selection on their functional traits, but it is unclear how differences in traits influence the niche dimensions of closely related bird species when they coexist in spatiotemporally heterogeneous environments.
ESNano: New insights into the dissimilatory reductive dissolution of different exposed facets of hematite
Recently, the research group of Professor Tongxu Liu from Institute of Eco-environmental and Soil Sciences, Guangdong Academy of Sciences has made new progress on the dissimilatory reductive dissolution of different exposed facets of hematite. This research was published in the journal of Environmental Science: Nano (IF = 7.683) and was selected as Outside Front Cover and Hot Article.
