It is challenging to efficiently and economically recycle many lithium-ion batteries(LIBs)because of the low valuation of commodity metals and materials,such as LiFePO_(4).There are millions of tons of spent LIBs where the barrier to recycling is economical,and to make recycling more feasible,it is required that the value of the processed recycled material exceeds the value of raw commodity *** presented research illustrates improved profitability and economics for recycling spent LIBs by utilizing the surplus energy in lithiated graphite to drive the preparation of organolithiums to add value to the recycled lithium *** study methodology demonstrates that the surplus energy of lithiated graphite obtained from spent LIBs can be utilized to prepare high-value organolithiums,thereby significantly improving the economic profitability of LIB ***(R-O-Li and R-Li)were prepared using alkyl alcohol(R-OH)and alkyl bromide(R-Br)as substrates,where R includes varying hindered alkyl *** organolithiums extracted from per kilogram of recycled LIBs can increase the economic value between$29.5 and$226.5 kg^(−1) *** value of the organolithiums is at least 5.4 times the total theoretical value of spent materials,improving the profitability of recycling LIBs over traditional pyrometallurgical($0.86 kg^(−1) cell),hydrometallurgical($1.00 kg^(−1) cell),and physical direct recycling methods($5.40 kg^(−1) cell).

Novel liquid scintillator radon detector

中国化学会第十届全国无机化学学术会议

作者： Lu Qiao Mixia Hu Jianming fan baohua Zhu College of Chemistry and Chemical Engineering Inner Mongolia University Key Lab of Fine Organic Synthesis Inner Mongolia Autonomous Region

Many studies have recently shown that low and safe dose of CO has been linked to display various physiological effects, such as anti-inflammatory, anti-apoptotic, anti-proliferative and vasodilation . However, it is also best known that CO is a highly toxic gas because of its high affinity toward hemoglobin to affect the oxygen transport, which restricts its practicability as inhaled gas for therapeutic application. Therefore, transition metal CO-releasing molecules(CORMs) were designed and developed in order to present an alternative way to deliver controlled amounts CO to cells and target tissues. Furthermore, the hydrogels are usually used as drug carrier due to their low irritation and good biocompatibility, which are similar to those of extracellular matrices . Herein, we report the preparation of the new phototriggered CO-releasing material, Ru-CORM@CS-PVA, by reactions of the Ru carbonyl complex with pH responsive hydrogel(CS-PVA) and its light-induced CO delivery properties.

关键词： Ru carbonyl complex CO release CS-PVA pH responsive

托盘包装的冷却肉在4℃贮藏过程中会流出血水并聚积在包装盒底部,血水与肉长时间接触不仅易滋生微生物,还会影响肉的色泽,加速冷却肉的腐败变质,缩短货架期。以脱乙酰基蟹壳粉为天然交联剂,不同体积分数的肉桂醛(0.3%、0.6%、0.9%、1.2%)为抑菌剂,获得了高强度、高吸水性的双交联海藻酸钠抑菌水凝胶吸水衬垫,用于吸收冷却肉在贮藏过程中渗出的血水。结果表明:脱乙酰基蟹壳粉与海藻酸钠之间发生了Ca^(2+)交联和聚电解质相互作用,肉桂醛的加入可显著改善材料的性能,当肉桂醛体积分数为0.6%与0.9%时,水凝胶吸水衬垫的结构更加致密并具有优异的溶胀性能、机械强度和抑菌能力。与未用吸水衬垫和使用木纤维吸水纸的处理组相比,海藻酸钠/蟹壳粉抑菌水凝胶吸水衬垫处理组冷却肉的pH值、挥发性盐基氮值、菌落总数与挥发性气味等指标的增幅显著降低(P<0.05),且汁液流失率少,汁液封存率为100%。海藻酸钠/蟹壳粉抑菌水凝胶吸水衬垫使用天然来源的蟹壳粉作为交联剂,脱乙酰基蟹壳粉与海藻酸钠形成双交联网络结构,不仅提高了材料的机械性能与凝胶强度,而且可提高废弃物的综合利用率,显示出了高于商业吸水衬垫的溶胀率,吸收冷却肉渗出物时可将渗出物封存于网状结构内部而不溢出,在减缓冷却肉微生物增殖和延长保质期方面具有一定优势。
