Lithium recovery from end-of-life Li-ion batteries(LIBs)through pyro-and hydrometallurgical recycling processes involves several refining stages,with high consumption of reagents and energy.A competitive technological alternative is the electrochemical oxidation of the cathode materials,whereby lithium can be deintercalated and transferred to an electrolyte solution without the aid of chemical extracting *** article investigates the potential to selectively recover Li from LIB cathode materials by direct electrochemical extraction in aqueous *** process allowed to recovering up to 98%of Li from high-purity commercial cathode materials(LiMn_(2)O_(4),LiCoO_(2),and Li Ni_(1/3)Mn_(1/3)Co_(1/3)O_(2))with a faradaic efficiency of 98%and negligible co-extraction of Co,Ni,and *** process was then applied to recover Li from the real waste LIBs black mass obtained by the physical treatment of electric vehicle battery *** black mass contained graphite,conductive carbon,and metal impurities from current collectors and steel cases,which significantly influenced the evolution and performances of Li electrochemical ***,due to concomitant oxidation of impurities,lithium extraction yields and faradaic efficiencies were lower than those obtained with high-purity cathode *** oxidation was found to occur within the voltage range investigated,but it could not quantitatively explain the reduced Li extraction *** fact,a detailed investigation revealed that above 1.3 V ***/Ag Cl,conductive carbon can be oxidized,contributing to the decreased Li *** on the reported experimental results,guidelines were provided that quantitatively enable the extraction of Li from the black mass,while preventing the simultaneous oxidation of impurities and,consequently,reducing the energy consumption of the proposed Li recovery method.

采用FRP增强的混凝土柱在使用过程中,可能受到轴向冲击荷载作用,但目前这方面的研究基本处于空白.通过对7组21个大尺寸CFRP约束混凝土方柱进行落锤轴向冲击试验,研究倒角半径r对约束柱抗冲击性能的影响.试验获取了锤头冲击力时程曲线、压缩变形时程曲线、FRP表面关键点的应变时程曲线和整个破坏过程的高速影像等信息.试验结果表明,CFRP约束混凝土方柱的破坏是由试件中部倒角位置处的CFRP被拉断所导致的,试件的破坏现象与倒角半径r有关;倒角半径r对约束柱的冲击性能有显著影响,r越大,冲击应力峰值和能量密度也越大;CFRP约束混凝土方柱的动力增大系数（DIF）随倒角半径比r.的增大而减小,基本成线性关系,在1.23-1.82之间.

Suspended particulate mercury associated with tidal fluxes in a lagoon environment impacted by cinnabar mining activity(northern Adriatic Sea)

Journal of Environmental Sciences 2018年第6期30卷 100-113页

The Isonzo River has been demonstrated to be a continuing point source of mercury（Hg）in the Gulf of Trieste although the Idrija mine was last active in 1996. The present study aims to investigate the role of the suspended particulate matter（SPM） associated with tidal fluxes to disperse particulate Hg（PHg） into the Grado coastal lagoon system. PHg concentrations（avg. 3.11 ± 2.62 μg/g, d.w.）, notwithstanding the ebb or flood tides, were significantly higher than the local sediment background（0.13 μg/g）. The relative affinity of Hg for the particulate phase in surface waters was confirmed by higher average distribution coefficient（Kd） values（5.6–6.7）. PHg contents showed the highest values in ebb tide conditions, thus suggesting their origin from the erosion of tidal flats and saltmarshes of the lagoon. When compared to river discharge, high PHg surface concentrations in flood tide are related to rainfall events occurring within the river basin. Results can be used to make an indicative assessment of the amount of Hg bound to SPM which is transported in and out of the lagoon basin following the action of tidal fluxes. A simple estimation provides a negative budget for the Grado lagoon sub-basin which loses between 0.14 and 1.16 kg of PHg during a tidal semi-cycle. This conclusion is in agreement with the evidence of morphological deterioration which has emerged from recent studies on the lagoon environment, and which testifies to a current sedimentary loss from the lagoon into the northern Adriatic Sea.

Clinical applications of squamous cell carcinoma antigenimmunoglobulins M to monitor chronic hepatitis C

引用

World Journal of Hepatology 2015年第29期7卷 2913-2919页

作者： Andrea Martini Andrea Gallotta Patrizia Pontisso giorgio Fassina Department of Medicine University of Padua Xeptagen S.p.A. VEGA Science Park

Hepatitis C virus(HCV) is the main cause of chronic liver disease and cirrhosis in Western countries. Over time, the majority of cirrhotic patients develop hepatocellular carcinoma(HCC), one of the most common fatal cancers worldwide- fourth for incidence rate. A high public health priority need is the development of biomarkers to screen for liver disease progression and for early diagnosis of HCC development, particularly in the high risk population represented by HCV-positive patients with cirrhosis. Several studies have shown that serological determination of a novel biomarker, squamous cell carcinoma antigen-immunoglobulins M(SCCA-Ig M), might be useful to identify patients with progressive liver disease. In the initial part of this review we summarize the main clinical studies that have investigated this new circulating biomarker on HCV-infected patients, providing evidence that in chronic hepatitis C SCCA-Ig M may be used to monitor progression of liver disease, and also to assess the virological response to antiviral treatment. In the last part of this review we address other, not less important, clinical applications of this biomarker in hepatology.
