1Hydrometallurgical recycling of NdF eB magnets: Complete leaching, iron removal and electrolysis显示文摘NdFeB magnets currently dominate the magnet market. Supply risks of certain rare earth metals(REM), e.g. Nd and Dy, impose efficient recycling schemes that are applicable to different types and compositions of these magnets with minimum use of chemicals and waste generation. In this study, a hydrometallurgical method was studied that could be adjusted to recover not only REM, but also other valuable metals(e.g.Co, Ni and Cu) that co-existed in the magnet. The magnet powders were completely dissolved in a dilute sulfuric acid solution giving more than 98% of dissolved iron in the ferrous state. Chemical oxidation of Fe^(2+) into Fe^(3+) by the addition of MnO 2 required only 1 h at ambient temperature. It was then possible to precipitate more than 99% of this ferric iron by adjusting the pH of the solution above 3 with either Ca(OH)_2 or MnO additions. However, the addition of Ca(OH)_2 resulted in the formation of gypsum and up to ca. 23% REM losses, possibly via co-precipitation into the gypsum. MnO elevated the Mn^(2+) concentration in the solution. However, it was found to be problematic that subsequent direct electrolysis removed Mn and Co. Low anodic current efficiencies(ACE) resulted in high energy consumption(EC), while incomplete Mn and Co removals and undesired REM losses were reported. Pre-electrolysis removals of REM and/or Co by oxalate and/or sulfide precipitation were proven to be successful and selective, but this enlarged the flowsheet considerably with only minor improvement of the Mn removal, ACE and EC.Mehmet Ali Recai Onal Chenna Rao Borra Muxing Guo Bart Blanpain Tom Van Gerven 2017Journal of Rare Earths2017,35,6:6
2Auto immune hepatitis显示文摘To provide an update of the latest trends in epidemiology, clinical course, diagnostics, complications and treatment of auto immune hepatitis(AIH). A search ofthe MEDLINE database was performed using the search terms: 'auto immune hepatitis', 'clinical presentation', 'symptoms', 'signs', 'diagnosis', 'auto antibodies', 'laboratory values', 'serology', 'histopathology', ' h i s t o l o g y ', ' g e n e t i c s ', 'HLA g e n e s ', 'non-HLA genes', 'environment', 'epidemiology', 'prevalence', 'incidence', 'demographics', 'complications', 'HCC', 'PBC', 'PSC', 'corticosteroid', 'therapy', 'treatment', 'alternative treatment'. English-language full-text articles and abstracts were considered. Articles included reviews, meta-analysis, prospective retrospective studies. No publication date restrictions were applied. AIH is an immune meditated progressive inflammatory liver disease that predominantly affects middle-aged females but may affect people of all ages. The clinical spectrum of AIH is wide, ranging from absent or mild symptoms to fulminant hepatic failure. The aetiology of AIH is still unknown, but is believed to occur as the consequence of an aberrant immune response towards an un-known trigger in a genetically susceptible host. In the absence of a gold standard, diagnosis is based on the combination of clinical, biochemical and histopathological criteria. Immunosuppressive treatment has been the cornerstone of treatment since the earliest description of the disease in 1950 by Waldenstr?m. Such treatment is often successful at inducing remission and generally leads to normal life expectancy. Nevertheless, there remain significant areas of unmet aetiological a clinical needs including fundamental insight in disease pathogenesis, optimal therapy, duration of treatment and treatment alternatives in those patients unresponsive to standard treatment regimens.nicole mf van gerven ynto s de boer chris jj mulder carin mj van nieuwkerk gerd bouma 2016World Journal of Gastroenterology2016,22,19:3

4Mechanochemical-Assisted Leaching of Lamp Phosphors: A Green Engineering Approach for Rare-Earth Recovery显示文摘稀土元素(REE)是设计和开发可持续能源应用的重要金属。从富含稀土元素的废物流中回收这些元素对实现独立、可持续的未来能源供应至关重要。本文比较了从绿灯荧光体LaPO_4:Ce^(3+),Tb^(3+)回收稀土元素的两种机制:在湿法冶金酸浸工艺前与溶剂冶金机械化学浸出工艺前的机械活化机制。稀土元素浸出率在机械活化后增加60%,完成机械化学浸出工艺后增加98%。高分辨率透射电子显微镜(HR-TEM)成像揭露了系统元素浸出率增加的原因:浸出与浸出模式的改善可归因于晶体形态从单晶体到多晶体的转变。多晶形材料的雏晶尺寸减小至纳米级,使化学单元出现不规则填充,导致晶体内缺陷颗粒边界的增加,从而增强浸出工艺。发明了一种溶剂冶金法将机械活化与浸出工艺结合成一个步骤,这有利于降低运营成本。其结果是简单、高效的工艺提供了更加绿色的荧光体废物回收替代途经。Steff Van Loy Koen Binnemans Tom Van Gerven 2018Engineering2018,4,3:3
5Human pharmacology of positive GABA-A subtype-selective receptor modulators for the treatment of anxiety显示文摘Anxiety disorders arise from disruptions among the highly interconnected circuits that normally serve to process the streams of potentially threatening stimuli. The resulting imbalance among these circuits can cause a fundamental misinterpretation of neural sensory information as threatening and can lead to the inappropriate emotional and behavioral responses observed in anxiety disorders. There is considerable preclinical evidence that the GABAergic system, in general, and its α2- and/or α5-subunit-containing GABA(A) receptor subtypes, in particular, are involved in the pathophysiology of anxiety disorders. However, the clinical ef?cacy of GABA-A α2-selective agonists for the treatment of anxiety disorders has not been unequivocally demonstrated. In this review, we present several human pharmacological studies that have been performed with the aim of identifying the pharmacologically active doses/exposure levels of several GABA-A subtype-selective novel compounds with potential anxiolytic effects. The pharmacological selectivity of novel α2-subtype-selective GABA(A) receptor partial agonists has been demonstrated by their distinct effect profiles on the neurophysiological and neuropsychological measurements that reflect the functions of multiple CNS domains compared with those of benzodiazepines, which are nonselective, full GABA(A) agonists. Normalizing the undesired pharmacodynamic side effects against the desired on-target effects on the saccadic peak velocity is a useful approach for presenting the pharmacological features of GABA(A)-ergic modulators. Moreover, combining the anxiogenic symptom provocation paradigm with validated neurophysiological and neuropsychological biomarkers may provide further construct validity for the clinical effects of novel anxiolytic agents. In addition, the observed drug effects on serum prolactin levels support the use of serum prolactin levels as a complementary neuroendocrine biomarker to further validate the pharmacodynamic measurements used during the clinical pharmacological study of novel anxiolytic agents.Xia Chen Joop van Gerven Adam Cohen Gabriel Jacobs 2019Acta Pharmacologica Sinica2019,40,5:2
