| 1 | Exploring BH_2CN-based hydrophobic hypergolic fuels and effective fuel“additives”: Imidazolylidene cyanoborane complexes显示文摘Two hydrophobic imidazolylidene-cyanoborane complexes were prepared by the introduction of{BH2 CN} into the molecular formula via treatment of imidazolium iodide and Na BH3 CN avoiding literature's tedious and hazardous procedures. These two complexes were fully characterized using IR spectroscopy,~1 H NMR and^(13)C NMR spectroscopy and high-resolution mass spectrometer. The X-Ray structure of NHC-1 has been determined. NHC-2 was proved to be hypergolic with WFNA and displayed the attractive properties such as water immiscibility, wide liquid range(Tg= -22C), short ignition delay time(13 ms), high density(0.98 g/cm3), good density impulse(r Isp, 347 s g cm^(-3)), showing the promising application potential as a fuel and an efficient fuel additive. | Xingye Li Jiayu Nan Tian Lu Hongyu Huo Yanqiang Zhang Haibo Li Fude Nie Hongquan Yin Fu-Xue Chen | 2018 | Chinese Chemical Letters2018，29，6： | 3 |

| 3 | WWP2 ameliorates oxidative stress and inflammation in atherosclerotic mice through regulation of PDCD4/HO-1 pathway显示文摘WWP2 is a HECT-type E3 ubiquitin ligase that regulates various physiological and pathological activities by binding to different substrates,but its role in atherosclerosis(AS)remains largely unknown.The objective of the present study is to investigate the role and underlying molecular mechanisms of WWP2 in endothelial injury.We found that WWP2 expression is significantly decreased in Apolipoprotein E(ApoE)-/-mice.Overexpression of WWP2 attenuates oxidative stress and inflammation in AS mice,while knockdown of WWP2 has opposite effects.WWP2 overexpression alleviates oxidized low-density lipoprotein(ox-LDL)-induced human umbilical vein endothelial cell(HUVEC)injury,evidenced by the decreased oxidative stress levels and the secretion of inflammatory cytokines.Programmed cell death 4(PDCD4)is identified as a potential substrate of WWP2.Co-immunoprecipitation(Co-IP)further demonstrates that WWP2 interacts with PDCD4,which is enhanced by ox-LDL treatment.Furthermore,the level of PDCD4 ubiquitination is significantly increased by WWP2 overexpression under the condition of MG132 treatment,while WWP2 knockdown shows opposite results.Subsequently,rescue experiments demonstrate that WWP2 knockdown further aggravates oxidative stress and inflammation in ox-LDL-treated HUVECs,while knockdown of PDCD4 alleviates this effect.Moreover,the use of sn-protoporphyrin(SnPP),an inhibitor of HO-1 pathway,confirms that PDCD4 enhances endothelial injury induced by ox-LDL through inhibiting HO-1 pathway.In conclusion,our results suggest that WWP2 protects against atherosclerosis progression via the PDCD4/HO-1 pathway,which may provide a novel treatment strategy for atherosclerosis. | Xingye Wang Lu Ma Songlin Zhang Qiang Song Xumei He Jun Wang | 2022 | Acta Biochimica et Biophysica Sinica2022，54，8： | 0 |
| 4 | Zigzag magnetic order in a novel tellurate compound Na_(4-δ)NiTeO_6 with S=1 chains显示文摘Na_(4-δ)Ni Te O_(6) is a rare example in the transition-metal tellurate family of realizing an S=1 spin-chain structure.By performing neutron powder diffraction measurements,the ground-state magnetic structure of Na_(4-δ)Ni Te O_(6) is determined.These measurements reveal that below T_N~6.8(2)K,the Ni^(2+) moments form a screwed ferromagnetic(FM)spin-chain structure running along the crystallographic a axis but these FM spin chains are coupled antiferromagnetically along the b and c directions,giving rise to a magnetic propagation vector of k=(0,1/2,1/2).This zigzag magnetic order is well supported by first-principles calculations.The moment size of Ni^(2+) spins is determined to be 2.1(1) μ_(B) at 3 K,suggesting a significant quenching of the orbital moment due to the crystalline electric field(CEF)effect.The previously reported metamagnetic transition near H_(c)~0.1 T can be understood as a field-induced spin-flip transition.The relatively easy tunability of the dimensionality of its magnetism by external parameters makes Na_(4-δ)Ni Te O_(6)a promising candidate for further exploring various types of novel spin-chain physics. | Cheng Su Xu-Tao Zeng Yi Li Nvsen Ma Zhengwang Lin Chuandi Zhang Chin-Wei Wang Ziyu Chen Xingye Lu Wei Li Xian-Lei Sheng Wentao Jin | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，9： | 0 |
