| 1 | An ethnobotanical study of forage plants in Zhuxi County in the Qinba mountainous area of central China显示文摘In the Qinba mountainous area of Central China,pig farming has a significant impact on the growth of the rural economy and has substantially increased farmer incomes.Traditional knowledge plays an important role in the selection of forage plant species for pig farming by local people.This study aimed to identify the forage plants used for pig feeding and to catalog indigenous knowledge regarding their use.During 2016 and 2017,ethnobotanical surveys and inventories were conducted in Zhuxi County,Hubei Province,China.Data were collected using semi-structured interviews,key informant reports,free listings,guided field walks,and participatory observations with 77 households in 16 villages in 13 towns/townships.The obtained data were analyzed using a relative frequency citation(RFC)index.Overall,145 wild forage plants from 91 genera and 31 families were recorded.The most cited families were Asteraceae,Polygonaceae,Urticaceae,Amaranthaceae,Fabaceae,Cruciferae,Caryophyllaceae,and Lamiaceae.Whole plants(75.9%)and tender leaves(12.4%)were the most frequently used parts of the plants.Most of the forage plants were herbaceous(88.9%).Almost all forage plants could be collected throughout the year(62.7%).Raw and cooked were the two main preparation methods.The most frequently cited species were Taraxacum mongolicum,Bidens pilosa,Sonchus oleraceus,Pilea verrucosa,and Pilea pumila var.obtusifolia.A total of 14 species were identified as the top forage plants in Zhuxi County based on their RFC values(RFC value greater than 0.5).Local people possess rich traditional knowledge about the utilization and management of forage plants for pig feeding.However,the maintenance of this traditional knowledge may be seriously threatened by changes in pig feeding modes and the lack of successors.Appropriate strategies and action plans have been suggested for the conservation of traditional knowledge associated with biodiversity and the sustainable use of forage species resources.These include 1)taking targeted measures to protect forage resources and associated traditional knowledge;2)strengthening research on the forage plants with the highest RFC values for nutritional value,digestibility,other functions,and ecological status;and 3)enhancing the identification of poisonous forage plants. | Jun Yang Jifeng Luo Qiliang Gan Leiyu Ke Fengming Zhang Hairu Guo Fuwei Zhao Yuehu Wang | 2021 | Plant Diversity2021，43，3： | 3 |
| 2 | Tunable Multicolor Circularly Polarized Luminescence via Co-assembly of One Chiral Electron Acceptor with Various Donors显示文摘Chiroptical materials with multicolor and signinvertible circularly polarized luminescence(CPL)are important for advanced optical devices and display technologies.Here,a general strategy is developed to generate CPL with highly tunable emission bands and handedness through charge-transfer(CT)complexation and co-assembly of one chiral non-emissive tetranitrofluorene-based acceptor with various achiral purple to blue emissive donors.The resulting assemblies exhibit intense CPL with a rich array of colors(519-668 nm)and prominent dissymmetry factors(|glum|)in the range of 10^(-3)-10^(-2).Notably,the CPL sign can be readily inverted by slightly changing the molecular structure of achiral donors.Single-crystal analysis reveals that the donor and acceptor molecules are alternately and asymmetrically packed in a lamellar fashion through CT interactions,leading to efficient transfer of chirality.Furthermore,the refined packing is mediated by the intensity and manner of CT interactions,rendering an inversion of chirality.The chiral co-assembly not only occurs for planar achiral donor molecules,but is also accessible to nonplanar conjugated molecules such as[4]helicene derivatives.Thus,the CPL feature of the resulting products can be easily and broadly manipulated,aiming at advanced chiroptical systems. | Fang Wang Chengshuo Shen Fuwei Gan Guoli Zhang Huibin Qiu | 2023 | CCS Chemistry2023，5，7： | 0 |
| 3 | Tunable construction of transition metal-coordinated helicene cages显示文摘We report a facile and tailored method to prepare globally twisted chiral molecular cages through tunable coordination of bis-bipyridine-terminated helicene ligands to a series of transition metals including Fe(Ⅱ), Co(Ⅱ), Ni(Ⅱ) and Zn(Ⅱ). This system shows an efficient remote transfer of stereogenecity from the helicene core to the bipyridine-metal coordination sites and subsequently the entire cages. While the Fe(Ⅱ), Co(Ⅱ) and Ni(Ⅱ)-derived M_(2)L_(3)(M for metal and L for ligand) cages exhibit quasi-reversible redox features, the Zn(Ⅱ) analogues reveal prominent yellow circularly polarized luminescence. Interestingly,with the addition of Na_(2)SO_(4), the Zn_(2)L_(3)cages reassemble into sextuple-stranded Zn_(6)L_(6)(SO_(4))_(4)cages in which three Zn_(2)L_(2) units are bound together by four sulfates and further coalesced by offset inter-ligandπ-π interactions. | Yongle Ding Chengshuo Shen Fuwei Gan Jinghao Wang Guoli Zhang Lingling Li Mouhai Shu Bangshang Zhu Jeanne Crassous Huibin Qiu | 2021 | Chinese Chemical Letters2021，32，12： | 0 |
| 4 | Modulation of the Anisotropic Electronic Properties in ReS_(2) via Ferroelectric Film显示文摘Anisotropic response in two-dimensional materials has emerged with attractive potential applications in angle-sensitive areas.However,the challenge with current studies on anisotropic response is due to the main use of the structural materials of pristine to examine the physical properties in different direc-tions,which cause restriction of the anisotropic ratio within a narrow range,thereby,limiting their practical applications. | Renyan Wang Fengya Zhou Liang Lv Shasha Zhou Yiwei Yu Fuwei Zhuge Huiqiao Li Lin Gan Tianyou Zhai | 2019 | CCS Chemistry2019，1，3： | 0 |
| 5 | Helical Conformation Tunability via Hydrogen Bonding in Supramolecular Frameworks显示文摘Hydrogen-bonded molecules and their dynamics are significantly important in chemistry and biology due to their widespread functionality.Besides their natural abundance and diversity,applications of molecules with dynamic conformations in artificial networks allow information storage and molecular motor design on the nanometer scale.Here,we report hydrogen-bonded molecular networks with tunable helical conformation on metal surfaces.The dynamics of helical conformation in two-dimensional hydrogenbond networks are triggered and resolved by scanning probe microscopy at the single-molecule level.In combinationwith theoretical calculations,the surfacespecific hydrogen bonds are identified as the origin of the dynamic helical conformation.Our results provide a distinctive access to molecular architecture with tunable helical conformation driven by hydrogenbond interaction on surfaces. | Zhijie Xue Fuwei Gan Hong Liu Chengshuo Shen Huibin Qiu Bo Yang Ping Yu | 2022 | CCS Chemistry2022，4，4： | 0 |
