以鲣鱼碎肉为对象,以硫代巴比妥酸值、氮溶解指数、质构、色差和感官评分为指标,探究不同挤压参数对挤压样品品质特性的影响。在此基础上,通过3因素3水平正交试验确定最优挤压膨化工艺:物料水分质量分数为25%、末端温度为130℃、螺杆频率为15 Hz。据此参数制得样品的感官总评分最高,为8.4分。从鲣鱼碎肉和挤压膨化样品中共检出了36种挥发物,确定了以己醛为代表的14种气味活性物质。经挤压膨化后鲣鱼碎肉中挥发物总质量分数从666.46 ng/g提高至2646.13 ng/g,以己醛为代表的不良风味物质质量分数显著下降,而以呋喃类为代表的熟化风味物质开始生成。研究成果可为金枪鱼肉加工企业提供理论参考和方法借鉴。

Co-free Li-rich Mn-based layered oxides are promising candidates for next-generation lithium-ion batteries(LIBs)due to their high specific capacity,high voltage,low ***,their commercialization is hindered by limited cycle life and poor rate ***,an in-situ simple and low-cost strategy with a nanoscale double-layer architecture of lithium polyphosphate(LiPP)and spinel phase covered on top of the bulk layered phase,is developed for Li_(1.2)Mn_(0.6)Ni_(0.2)O_(2)(LMNO)using Li^(+)-conductor LiPP(denoted as LMNO@S-LiPP).With such a double-layer covered architecture,the half-cell of LMNO@S-LiPP delivers an extremely high capacity of 202.5 mAh·g^(−1)at 1 A·g^(−1)and retains 85.3%of the initial capacity after 300 cycles,so far,the best highrate electrochemical performance of all the previously reported *** energy density of the full-cell assembled with commercial graphite reaches 620.9 Wh·kg^(−1)(based on total weight of active materials in cathode and anode).Mechanism studies indicate that the superior electrochemical performance of LMNO@S-LiPP is originated from such a nanoscale double-layer covered architecture,which accelerates Li-ion diffusion,restrains oxygen release,inhibits interfacial side reactions,suppresses structural degradation during ***,this strategy is applicable for other high-energy-density cathodes,such as LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2),Li_(1.2)Ni_(0.13)Co_(0.13)Mn_(0.54)O_(2),LiCoO_(2).Hence,this work presents a simple,cost-effective,scalable strategy for the development of high-performance cathode materials.

Beijing Review 2017年第14期60卷 26-28页

作者： Yin Pumin wu manman

When Zhu Hui sat down to watch the match between China and Iran on the night of March 28, there was littleoptimism about the chances of the Chinese national team. They had lost almost all their group matches, and only a surprise victory over South Korea a week earlier had kept their hopes alive of surviving the qualifying rounds to reach the 2018 FIFA World Cup.
