In this work,a novel composite material based on β-cyclodextrin-immobilized sodium alginate aerogel(β-CD/NaAlg) was developed utilizing cross-linker of epichlorohydrin and applied as an adsorbent to remove tetracycline antibiotics from reclaimed wastewater.A series of characterizations were utilized to confirm the successful synthesis of the adsorbent and this β-CD/NaAlg presented a three-dimensional network at the nanoscale or *** optimal conditions(pH=4,t=8 h,β-CD:NaAlg=9,adsorbent dosage = 1.5 g·L-1),the maximum removal rate of β-CD/NaAlg to tetracycline was 70%.The adsorption behavior of tetracycline on β-CD/NaAlg conformed to the Freundlich isotherm model(R2=0.9977) and the pseudo-second-order kinetic model(R^(2)=0.9993).Moreover,the adsorbent still removed 55.3% of tetracycline after five ***,the adsorbent was integrated with ultrafiltration to adsorb tetracycline antibiotics from simulated reclaimed wastewater,and the removal rate of tetracycline reached 78.9% within 2 *** existence of Cr(Ⅵ) had a negligible impact on tetracycline removal,while the presence of humic acid exhibited a promoting *** possible adsorption mechanisms were also elucidated through X-ray photoelectron spectroscopy and density functional theory *** summary,β-CD/NaAlg represents an environmentally friendly,efficient,and sustainable adsorbent for removing tetracycline antibiotics from reclaimed water.

We provide an investigation of the spectroscopic factor of resonance states in A=5-8 nuclei,utilizing the Gamow shell model(GSM).Within the GSM,the configuration mixing is taken into account exactly with the shell model framework,and the continuum coupling is addressed via the complex-energy Berggren ensemble,which treats bound,resonance,and non-resonant continuum single-particle states on an equal *** a result,both the configuration mixing and continuum coupling are meticulously considered in the *** first calculate the low-lying states of helium isotopes and isotones with the GSM,and the results are compared with that of ab initio no-core shell model(NCSM)*** results indicate that GSM can reproduce the low-lying resonance states more accurately than the *** this,we delve into the spectroscopic factors of the resonance states as computed through both GSM and NCSM,concurrently conducting systematic calculations of overlap functions pertinent to these resonance ***,the calculated overlap function and spectroscopic factor of6He(01+)■νp3/2→^(7)He(3/2_(1)-)with GSM are compared with the results from ab initio NCSM,variational Monte Carlo,and Green’s function Monte Carlo calculations,as well as available experimental *** results assert that wave function asymptotes can only be reproduced in GSM,where resonance and continuum coupling are precisely addressed.

The metastable retained austenite(RA)plays a significant role in the excellent mechanical performance of quenching and partitioning(Q&P)steels,while the volume fraction of RA(V_(RA))is challengeable to directly predict due to the complicated relationships between the chemical composition and process(like quenching temperature(Qr)).A Gaussian process regression model in machine learning was developed to predict V_(RA),and the model accuracy was further improved by introducing a metallurgical parameter of martensite fraction(fo)to accurately predict V_(RA) in Q&P *** developed machine learning model combined with Bayesian global optimization can serve as another selection strategy for the quenching temperature,and this strategy is very effcient as it found the"optimum"Qr with the maximum V_(RA) using only seven consecutive *** benchmark experiment also reveals that the developed machine learning model predicts V_(RA) more accurately than the popular constrained carbon equilibrium thermodynamic model,even better than a thermo-kinetic quenching-partitioning-tempering-local equilibrium model.

我国刑事诉讼的比较研究大致经历了介译阐释、效法借鉴以及反思批判三个阶段,积累了较为丰富的研究成果,并呈现出研究进路日益多元、研究内容逐渐深化、研究目标实用主义导向等特征。然而,存在研究视角重文本轻实践、比较对象缺乏系统性、研究内容缺乏深刻性等不足,在一定程度上制约了比较刑事诉讼研究的进一步发展。未来,应调整研究进路、更新研究对象,在做好域外刑事司法实证研究的基础上,转换研究视角与立场,立足中国的现实需要,打造比较刑事诉讼的中国流派,传播中国刑事诉讼学者的国际声音,助力国际刑事诉讼规则的建立与对中国制度的认同。

红宝石的热处理属于优化处理,常用硼砂作助熔剂。在市场中热处理红宝石被以天然红宝石出售,价值颇高,但裂隙中硼砂的含量多少会影响到售价的高低。因此,对此类红宝石中的硼砂进行定量研究,应用NanoVoxel-4000X型射线计算机断层扫描仪对样品进行扫描分析,从而获得裂隙中充填物硼砂的2D图像。用明暗灰度值表征裂隙中不同密度的物质;充填物硼砂分布的3D图像中用不同的颜色表征其三维厚度。通过比较表征厚度的色标,可直观看到硼砂的整体含量小。同时样品的硼砂的厚度分布直方图显示所有裂隙内硼砂的厚度都小于130μm,所有硼砂的厚度和体积比都小于10%,也说明填充量小。最后通过Avizo 9.0软件对红宝石样品和硼砂的含量进行阈值分割,得到两者的实际体积,然后可计算出硼砂含量的体积占红宝石总体积的百分比。本实验样品中充填物硼砂体积比例为10.69%,这既是热处理红宝石中硼砂定量检测中的一个重要指标,也为研究热处理红宝石中硼砂的定量分级标准提供了数据支撑。
