The high-value utilization of industrial solid waste using a facile and eco-friendly process is of great interest and significance in reducing environmental pollution and developing a green circular economy. Herein, we propose an amyloid-mediated molecular engineering strategy to transform particulate waste into valuable adsorbents for metal ions. Our method has the advantage of aqueous solution fabrication under mild conditions without the use of high-temperature hydrothermal methods and toxic chemical reagents. Amyloid-mediated molecular engineering manipulates the phase transition of bovine serum albumin(BSA)on particulate waste surfaces, resulting in a remarkable ～3.1 times improvement in the adsorption capacity of fly ash, a typical industrial solid waste for gold ions after modification with the phase-transitioned BSA(PTB). The resultant adsorption ability was 69–1,980 times higher than those of conventional and emerging adsorbent materials such as ion exchange resins, activated carbon(AC), covalent organic frameworks(COFs), and metal-organic frameworks(MOFs). We further demonstrated the application of our PTB-modified materials in the recovery of precious metals from low-grade gold ore and electronic waste leachates. Consequently, this strategy could increase the value of waste materials nearly 27 times. In addition, this method is generally extendable to other conventional industrial adsorbents such as resin, clay, and Al2O3, and enhances their adsorption capabilities at least twofold. Overall, this work provides a simple and green approach for improving the adsorption performance of solid particles, and is expected to develop into a universal strategy for transforming waste particles into high-value-added products.

研究了不同电流密度下柠檬酸碱性镀铜过程中镀层厚度随电镀时间的变化规律。在对镀层成分、阴极极化曲线等分析的基础上建立了该工艺条件下镀层厚度的预测模型。结果表明:该模型对镀层厚度的预测值与实测值之间有很好的相关性,可准确地预测不同电流密度、电镀时间下的镀层厚度。基于该模型还建立了该电镀过程中电流效率与相关工艺参数的数学关系。这些将为柠檬酸碱性镀铜的生产实践提供很好的指导。

There is a lack of accurate pediatric reference intervals(RIs) in China, with most commonly used RIs established without consideration of the effect of age and gender. The Pediatric Reference Intervals in China(PRINCE) project aims to establish and verify pediatric RIs for 31 common laboratory *** project will be a large, multicenter cross-sectional study:14,490 healthy children and adolescents aged up to 19 years will be surveyed by 10 children's hospitals and one pediatric department of a university hospital. To evaluate the feasibility and efficiency of the study methods, 602 children were surveyed in the pilot phase of the PRINCE study in April 2017: it found that some measurands were distinctly age dependent and that there were differences between values for males and females. The results of the pilot study affirmed the necessity of the PRINCE project for Chinese pediatrics. The pilot also indicated potential difficulties in the full survey, e.g., difficulties in recruiting children aged under 3 years and insufficient collection of blood samples from infants. The operation of the PRINCE project has been modified based on the findings in the pilot study toward improving the validity of the PRINCE project and promoting its openness and transparency.

目的探讨140例缺血性脑血管疾病患者经颈部血管超声检查的结果及指导价值。方法回顾性分析2020年6月至2022年5月我院收治的140例缺血性脑血管疾病患者的临床资料,作为观察组,同时选取141例健康体检者的临床资料,作为对照组。两组受检者均接受经颈部血管超声检查。比较两组受检者颈动脉狭窄程度、斑块情况、血流动力学指标以及颈部病变检出部位情况,分析典型病例图片。结果观察组颈动脉中度、重度狭窄比率、颈动脉斑块发生率、阻力指数(RI)、收缩期峰值流速(PSV)、舒张末期血流速度(EDV)、平均血流速度(Vmean)水平、在颈内动脉起始处、颈总动脉主干处、颈总动脉窦处、颈动脉分叉处的病变检出率高于对照组,颈动脉正常比率低于对照组,差异有统计学意义(P0.05)。结论缺血性脑血管疾病应用经颈动脉超声检查,可有利于判断血管狭窄、斑块性质及病变分布情况,同时还可通过提供的脑血流动力学指标,进行准确判断患者的病情进展情况,以为临床后期治疗及预后提供一定的参考依据。
