Double [5]carbohelicene: facile synthesis, chiroptical properties,isomerization study, and lasing application

Double carbohelicenes have attracted considerable attention due to their aesthetic structures, distinct π-conjugation extension, inherent chirality, and intriguing optical and electronic properties. Herein, the concise de novo synthesis of a new double[5]carbohelicene 1 together with its chiroptical properties, isomerization process and lasing application is presented. 1 was synthesized by a simple protocol involving the formation of a 6,6′-bipentacene as the key intermediate. It is worth noting that1 existed as two diastereomers 1-PP/MM and 1-PM, which were successfully isolated and unambiguously confirmed by Xray crystallography. The optical resolution of the racemic 1-PP/MM was successfully achieved by chiral-phase highperformance liquid chromatography（HPLC）, and 1-PP and 1-MM were characterized by circular dichroism. Interestingly, it was found that 1-PP/MM could be completely isomerized to 1-PM upon heating, and the detailed thermodynamics and kinetics of the isomerization process were systematically investigated. 1-PM exhibited deep-red luminescence with emission maximum at 723 nm and fluorescence quantum yield as high as 32.95%. Consequently, we can showcase the lasing application of 1-PM by doping with epoxy resin to assemble a bottle microlaser spontaneously, which the lasing wavelength is 796.6 nm at a threshold of 0.8 m J cm-2. We believe that our studies, including the facile synthesis methodology, detailed isomerization studies, and lasing application, will shed some light on the design and synthesis of novel carbohelical systems with more functions.

Transforming waste particles into valuable adsorbents via amyloid-mediated molecular engineering

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.

桫椤(Alsophila spinulosa)是第三纪早期冰川的孑遗植物和世界上最古老的活化石之一,对研究古气候和物种变迁以及地理区系变化等具有重要的参考价值。基于桫椤在中国地区的111个有效分布点和10个环境因子,利用MaxEnt模型和ArcGIS软件对气候变化背景下桫椤在中国的潜在地理分布进行了预测,同时综合环境因子贡献率和刀切法检验评估了制约现代气候条件下桫椤潜在地理分布的重要因子。本研究还采用了响应曲线来确定环境因子的适宜值,进一步预测了气候变化背景下桫椤的潜在地理分布区和面积。结果表明:MaxEnt模型的预测准确度高,受试者工作曲线面积(AUC值)达0.959;现代气候条件下桫椤的潜在适宜生境面积为160.15×10^(4)km^(2),主要位于中国的南部和东南部地区;影响桫椤潜在地理分布的主要环境因子为气温因子(平均气温日较差和最干季平均温度)、降水因子(最干季降水量)和地形因子(坡度),其中最干季降水量是影响桫椤潜在地理分布的关键因子;在未来气候变化情景下,桫椤的总适宜生境面积增加,高适宜生境和中适宜生境面积减少,低适宜生境面积增加,桫椤的高适宜生境重心向西北方向和高纬度地区转移。研究结果将为桫椤的科学管理和资源保护提供理论依据。

针对大量中国游客涌入日本现象,日方商家以中国文字与色彩装饰店铺,不仅让中国旅游者有了亲切感、自豪感与认同感,也更加推助了旅游者购物的消费情绪,有学者将此类现象定位于捧杀①,但从技术层面可认为这是一种氛围替代,其适合于实物性的旅游纪念产品开发。作者继而认为应关注时间上的变动性,将其与产品非时间性的其他重要功能并列考虑,应把旅游当地与客源地纳入"同框处理",通过氛围改造以提高旅游者的消费情绪。

采用1992—2018年联合国商品贸易数据库数据,详细匹配、统计和分析了中国对中亚五国的农产品出口规模、结构和质量。结果表明:中国对中亚五国的农产品出口规模不断扩大,出口种类愈加齐全,贸易竞争力和显性比较优势不断增强;农产品出口结构由单一转向多元,由土地密集型农产品转向了劳动密集型农产品;农产品出口质量不断提升,且土地密集型农产品出口质量明显高于劳动密集型农产品出口质量,但始终处于高端质量的“低端”。根据研究结论,提出了建立农业全面合作长效机制、加强农产品市场监测预警与农产品信息分析、培育植根于本土新兴农业产业发展的出口贸易模式等对策建议。
