韩山师范学院（HANSHAN NORMAL UNIVERSITY），简称“韩山师院、韩师（HSNU）” ，是广东省属本科师范院校，是广东省与潮州市共建高校 ，联合国教科文组织中国创业教育联盟理事单位， 位于国家历史文化名城潮州市。 韩山师范学院创立于清光绪廿九年（1903年）的“惠潮嘉师范学堂”，其前身可追溯到宋元祐五年（公元1090年）潮人为纪念唐代大文学家韩愈而建立的“韩山书院”，1921年更名为省立第二师范学校，1935年更名为省立韩山师范学校，1949年更名为韩山师范学校，1958年升格为高等师范专科学校，1993年升格为本科师范学院。 截至2019年11月，学校校园占地面积97.6万平方米，建筑面积46.8万平方米，设有18个二级学院，开设58个本科招生专业，有教职工1400多人，有在读生19271人。
To explore the influence of substituent at C6 and C9 positions of phenanthroimidazole,three hot exciton blue emitters TPAPPI-Py,TPAPPI-mPy and TPAPPI-Qu were synthesized.Based on TPAPPI-Py,TPAPPI-mPy and TPAPPI-Qu as the emitting layers in OLEDs,the EQEmax of the devices are 4.80％,5.25％and 3.29％with CEmax of 5.46,5.05,3.75 cd·A-1,respectively.Those results indicated that the weak electron-withdrawing substituents at the C6 and C9 positions did not affect the emission wavelength,but was beneficial for enhancing carrier transport capability.The efficiency roll-off of the device remains below 10％in the luminance range from 1-1 000 cd·m-2,in-dicating their excellent electroluminescence.
ObjectiveTo analyse the quality evaluation methods for and nutrition evaluation of recombinant goose liver products.MethodsGoose liver is used as the raw ingredient and combined with chicken breast, while tapioca starch, soybean protein isolate, and transglutaminase (TG) are added as auxiliary materials, to prepare recombinant goose livers. The CRITIC-grey correlation analysis is employed to comprehensively score the color, cooking loss, and texture characteristics of recombinant goose livers made with different formulas. Then, the best formula is screened for nutritional index observation and nutrition evaluation.ResultsThe comprehensive score of recombinant goose livers is the highest at 208.93 with 15% goose livers, 85% chicken breast, 1.25% TG, 10% tapioca starch, and 2.5% soybean protein isolate. The moisture, protein, and fat content of recombinant goose livers are 64.86, 18.13, and 0.85 g/100 g, respectively. A total of 14 fatty acids are detected, including 9 unsaturated fatty acids and 5 saturated fatty acids, including linoleic acid, α-linolenic acid, and arachidonic acid. More importantly, the atherosclerosis index (AI) and thrombosis index (TI) are lower than 0.5. Additionally, essential amino acids/amino acids (EAA/TAA) and essential amino acids/nonessential amino acids (EAA/NEAA) are 43.25% and 76.22%, respectively, with methionine as the first limiting amino acid.ConclusionThe quality of recombinant goose livers is evaluated using the CRITIC-grey correlation analysis, which can reflect the quality characteristics of recombinant goose livers. Recombinant goose liver is a high-protein, low-fat food suitable for patients with cardiovascular and cerebrovascular diseases. Reasonably in amino acid composition, recombinant goose liver is a source of high-quality protein.
The development of new organic red emitters is of great importance for OLEDs and full-color displays.Two D-A-A′ type red emitters,named TPA-BT-S and TPA-BT-D,were designed and synthesized with triphenyl-amine as the electron donor(D),benzothiadiazole and 2,6-diphenyl-3,5-dicyanopyridine as the electron acceptors(A).In non-doped devices,the electroluminescent wavelengths of the two emitters are 618 nm and 610 nm,respec-tively,which are in the standard red light region.The maximum power efficiencies of the devices are 11.9 lm·W-1 and 12.0 lm·W-1,respectively;with maximum external quantum efficiencies of 6.36%and 5.32%,respectively.The exciton utilization of TPA-BT-S in the device reaches 33.7%.Those results demonstrate that emitters with hy-brid local and charge-transfer states characteristic and D-A-A′ structure will exhibit high efficiency.Those provides a reference for the development of high-efficiency red emitters.
