为探索生物质废弃物柚子皮资源化应用于含Cr^(6+)废水处理的可行性,研究采用以柚子皮为主要原料,通过调节柚子皮粉与改性剂FeCl_3的质量配比进行改性,将两者在常温下加水混合均匀后于(85±2)℃下烘干,粉碎后便可得到2种改性产物1号(FeCl_3质量分数为1%)和2号(FeCl_3质量分数为9%)。研究结果表明:1号产物对Cr^(6+)的最大单位吸附量为1.98 mg/g,吸附过程符合Langmuir吸附等温模型;而2号产物最大单位吸附量高达26.60mg/g,吸附反应动力学可用Freundlich吸附等温模型来描述;适当增大FeCl_3质量分数有利于提高改性柚子皮的吸附性能;改性柚子皮对Cr^(6+)的吸附去除可能是金属沉淀、静电吸附、絮凝作用和共沉淀作用的结果。

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.

A new method about purification of metallurgical grade silicon （MG-Si） by a combination of Si-Al solvent refining andgas blowing treatment was proposed. The morphologies and transformation of impurity phases, especially for boron and iron in Si-Al melt were investigated during Ar-H2 gas blowing treatment. The mechanism of boron removal was discussed. The resultsindicate that gas blowing can refine grain size and increase nucleation of the primary Si. Boron can be effectively removed fromMG-Si using the Ar-H2 gas blowing technique during the Si-Al solvent refining. Compared with the sample without gas blowing,the removal efficiency of boron increases from 45.83% to 74.73% after 2.5 h gas blowing. The main impurity phases containingboron are in the form of TiB2, AlB2 and VB compounds and iron-containing one is in the form of β-Al5FeSi intermetallic *** of boron combines [H] to transform into gas BxHy （BH, BH2） and diffuses towards the surface of the melt and is volatilized byAr-H2 gas blowing treatment under electromagnetic stirring.

Atmospheric turbulence is an important parameter affecting laser atmospheric transmission. This paper reports on a self-developed atmospheric turbulence detection Li DAR system (scanning differential image motion Li DAR(DIM-Li DAR) system). By designing and simulating the optical system of atmospheric turbulence detection Li DAR,the basic optical imaging accuracy has been determined.

Let （X, d） be a metric space and f be a continuous map from X to X. Denote by EP（f） and Ω（f） the sets of eventually periodic points and non-wandering points of f, respectively. It is well known that for a tree map f, the following statements hold：（1） If x ∈ Ω（f） - Ω（f^n） for some n ≥ 2, then x ∈ EP（f）. （2） Ω（f） is contained in the closure of EP（f）. The aim of this note is to show that the above results do not hold for maps of dendrites D with Card（End（D）） = No （the cardinal number of the set of positive integers）.

Objective To determine the prevalence of non-fatal injuries among children aged 5-14 years in China. Methods Data of 21 973 children aged 5-14 years were extracted from the Fourth National health Service Survey of China carried out between June 15 and July 10, 2008. Injury-related indicators included： history of ever having had an injury, and injury frequency, cause, location and severity. Results The overall prevalence of non-fatal injuries among the children in the previous 12 months was 17.0 per 1000 subjects. The leading causes of non-fatal injuries were falls, animal bites, traffic accidents, falling objects and burns. The majority of children sustained only one injury. The main place of injury was at home in 40% and 54% of urban boys and girls, respectively, at school in 48% of rural boys, and at home and at school each in 33% of rural girls. Medical treatment for one day was the main option for 80% of urban boys and girls, 84% of rural boys, and 72% of rural girls. Conclusion Nonfatal injuries among children aged 5-14 years are a serious public health concern in China.
