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。本研究比较了从绿灯荧光体LaPO4:Ce3+,Tb3+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。

Chalcogenide nanostructured semiconductor, copper sulfide (CuS) was prepared from copper and sulfur powders in stoichiometric ratio by a simple, fast, and convenient one-step mechanochemical synthesis after 40 min of milling in an industrial eccentric vibratory mill. The kinetics of the mechanochemical synthesis and the influence of the physical properties of two Cu powder precursor types on the kinetics were studied. The crystal structure, physical properties, and morphology of the product were characterized by X-ray diffraction (XRD), the specific surface area measurements, particle size distribution and scanning electron microscopy. The XRD analysis confirmed the hexagonal crystal structure of the product-CuS (covellite) with the average size of the crystallites 11 nm. The scanning electron microscopy analysis has revealed that the agglomerated grains have a plate-like structure composed of CuS nanoparticles. The thermal analysis was performed to investigate the thermal stability of the mechanochemically synthesized CuS. The optical properties were studied using UV-Vis and photoluminescence spectroscopy. The determined optical band gap energy 1.80 eV responds to the value of the bulk CuS, because of agglomerated nanoparticles. In addition, a mechanism of CuS mechanochemical reaction was proposed, and the verification of CuS commercial production was performed.

The distributions of ARGs were monitored in a WWTP in Harbin during six months. CASS had the best removal efficacy of ARGs compared to other processes in the WWTP. UV disinfection could effectively control the HGT. AGAC significantly remove ARGs and organics due to its high absorption capacity. Combination of ozone and AGAC significantly improve removal of ARGs and organics.

Chronic hepatitis B virus infection: epidemiology, prevention, and treatment in China

Chronic hepatitis B is a major health problem in China. The universal vaccination program since 1992 has changed the epidemiology of hepatitis B virus infection in China from highly to moderately endemic. The most prevalent hepatitis B virus strains in China are genotypes B and C, whereas those in western provinces are genotypes D and C/D hybrid. Chronic hepatitis B poses a heavy burden to the society in China. Different treatment strategies have been explored to improve patient outcomes in a cost-effective manner. However, antiviral drugs with a low genetic barrier to resistance are still extensively used because of the generally low income and limited resources in China. Individualized antiviral therapy is closely associated with translational medicine, which utilizes information from studies on genomics, immune biomarkers, and fibrosis. The results of these studies are crucial in further improving treatment outcomes.
