| 1 | The intrinsic mechanism of corrosion resistance for FCC high entropy alloys显示文摘The concept of high entropy alloys(HEAs) or multi-principal component alloys has inspired a great progress of physical metallurgy along with several unusual phenomena. The high corrosion resistance of HEAs was frequently mentioned but without convincing explanations. In this paper, the intrinsic mechanism of corrosion resistance in FCC HEAs was revealed by designing equal atomic alloys with single solid solution phase. The results showed that the Cr element in FCC HEAs played the dominant role in the corrosion resistance rather than the simple structure from high entropy effect or uniform element distribution. | shang xuliang wang zhijun he feng wang jincheng li junjie yu jiakang | 2018 | Science China(Technological Sciences)2018，61，2： | 11 |
| 2 | CSF-Based Analysis for Identification of Potential Serum Biomarkers of Neural Tube Defects显示文摘The protein composition of cerebrospinal fluid(CSF) in neural tube defects(NTDs) remains unknown. We investigated the protein composition of CSF from 9 infants with NTDs using isobaric tags for relative and absolute quantitation(iTRAQ). We identified 568 proteins in the CSF of infants with spina bifida, which is the most common type of NTD. Among these, 18 proteins were associated with neural tube closure in the CSF during human embryonic neurulation and 5 were involved in NTDs. Based on these results, an animal model was further utilized to investigate early serum biomarkers for NTDs.We found that the myristoylated alanine-rich C-kinase substrate, Kunitz-type protease inhibitor 2, andapolipoprotein B-100 protein levels were decreased in both embryos and the sera of pregnant Sprague-Dawley rats carrying embryos with NTDs. CSF proteins may be useful in the discovery of potential serum biomarkers for NTDs. | Xinyu Yan Lixin Mai Changchun Lin Wenji He Gengsheng Yin Jiakang Yu Lian Huang Sanqiang Pan | 2017 | Neuroscience Bulletin2017，33，4： | 3 |

| 4 | Biodegradation of waste refrigerator polyurethane by mealworms显示文摘Refrigerator insulation replacement results in discarding a large amount of waste refrigerator polyurethane(WRPU).Insect larvae like mealworms have been used to biodegrade pristine plastics.However,knowledge about mealworms degrading WRPU is scarce.This study presents an in-depth investigation of the degradation of WRPU by mealworms using the micro-morphology,composition,and functional groups of WRPU and the egested frass characteristics.It was found that the WRPU debris in frass was scoured,implying that WRPU was ingested and degraded by mealworms.The carbon content of WRPU-based frass was lower than that of WRPU,indicating that mealworms utilized WRPU as a carbon source.The urethane groups in WRPU were broken,and benzene rings’C=C and C–H bonds in the isocyanate disappeared after being ingested by mealworms.Thermal gravimetric-differential thermal gravimetry analysis showed that the weight loss temperature of WRPU-based frass was 300°C lower than that of WRPU,indicating that the thermal stability of WRPU deteriorated after being ingested.The carbon balance analysis confirmed that carbon in the ingested WRPU released as CO_(2) increased from 18.84%to 29.80%,suggesting that WRPU was partially mineralized.The carbon in the mealworm biomass ingesting WRPU decreased.The possible reason is that WRPU does not supply sufficient nutrients for mealworm growth,and the impurities and odor present in WRPU affect the appetite of the mealworms.The microbial community analysis indicated that WRPU exerts a considerable effect on the gut microorganism of mealworms.These findings confirm that mealworms degrade WRPU. | Ping Zhu Shuangshuang Gong Mingqiang Deng Bin Xia Yazheng Yang Jiakang Tang Guangren Qian Fang Yu Ashantha Goonetilleke Xiaowei Li | 2023 | Frontiers of Environmental Science & Engineering2023，17，3： | 0 |
