研究不同植物源生物质炭的性质,评价其对云南东川地区镉(Cd)污染应用效果。开展了稻秆炭(RBC)、麦秆炭(WBC)、玉米秆炭(MBC)、麻秆炭(HBC)、田菁炭(TBC)、花生壳炭(PBC)的Cd吸附特征研究和傅里叶变换红外光谱(FTIR)分析、X射线衍射(XRD)分析;通过盆栽试验分析了上述生物质炭对东川Cd污染土壤的Cd赋存形态和油麦菜Cd吸收的影响。结果表明,Langmuir吸附等温线及准二级动力学曲线能较好模拟生物质炭对Cd的吸附,TBC饱和吸附量最大分别为37.1和27.9mg·g^(-1);WBC、RBC、TBC解吸率较低,各浓度梯度下均不超过10%;FTIR分析表明田菁炭含有较多的含氧官能团;XRD分析表明各生物质炭元素种类存在差异。与不添加生物质炭处理(CK)比较,TBC处理土壤有效Cd降幅最大为24.3%,且达显著水平(P<0.05);同时土壤Cd形态由酸溶态向稳定态转化。与CK相比,HBC处理油麦菜地上Cd含量降幅最大为26.4%,且达显著水平;WBC、HBC处理显著降低油麦菜体内Cd的转运系数,转运系数分别为0.6620、0.6928。聚合增强树分析(ABT)分析结果表明,土壤可溶性有机碳(DOC)与土壤pH是土壤有效Cd的主要影响因素,呈极显著负相关,贡献率分别为33.0%和21.9%。综上,供试各植物源生物质炭能降低东川Cd污染土壤中Cd的有效性,减少植物对Cd的吸收及转运,不同生物质炭间存在差异。综合材料性质及试验结果,TBC是东川地区修复Cd污染土壤的较优材料选择。

作者： Changxi Liu Liqiang Wang Weijie Lu Jia Liu Chengliang Yang Chunhai fan Qian Li Yujin Tang State Key Laboratory of Metal Matrix Composites School of Material Science and EngineeringShanghai Jiao Tong UniversityNo.800 Dongchuan RoadShanghai 200240China Affiliated Hospital of Youjiang Medical University for NationalitiesBaiseGuangxi 533000China School of Chemistry and Chemical Engineering National Center for Translational MedicineShanghai Jiao Tong UniversityShanghai 200240China

Bioprinting is an emerging additive manufacturing technology that has enormous potential in bone implantation and repair. The insufficient accuracy of the shape of bioprinted parts is a primary clinical barrier that prevents widespread utilization of bioprinting,especially for bone design with high-resolution requirements. During the last five years, the use of computer vision for process control has been widely practiced in the manufacturing field. Computer vision can improve the performance of bioprinting for bone research with respect to various aspects, including accuracy, resolution, and cell survival rate. Hence, computer vision plays a substantial role in addressing the current defect problem in bioprinting for bone research. In this review, recent advances in the application of computer vision in bioprinting for bone research are summarized and categorized into three groups based on different defect types: bone scaffold process control, deep learning, and cell viability models. The collection of printing parameters,data processing, and feedback of bioprinting information, which ultimately improves printing capabilities, are further discussed. We envision that computer vision may offer opportunities to accelerate bioprinting development and provide a new perception for bone research.
