| 1 | Orange-red, green, and blue fiuorescence carbon dots for white light emitting diodes显示文摘Fluorescent carbon dots(CDs) are admirable nanomaterials due to their superior optical properties and low cost.However,regulation of the emission colors in CDs for lighting device still remains a challenge.In this work,we developed a green hydrothermal method to obtain three emission colors of CDs using L-tyrosine(for blue CDs),o-phenylendiamine(for green CDs) and L-tyrosine/o-phenylendiamine mixture(for orange-red CDs).These CDs possess good water dispersibility,strong emission with high quantum yields,and excellent photostability.Furthermore,the resulting CDs were dispersed in polyvinyl alcohol(PVA) matrix to yield solid state films,where the self-quenching effect in solid state was effectively avoided.A full-color light-emitting diode was fabricated by packing the CDs-PVA composites on the top of a UV-chip,which have superior potential applications in CDs-based solid-state lighting system. | Ling Jin Li Zhang Lei Yang Xingrong Wu Cheng Zhang Kang Wei Lifang He Xinya Han Hongbin Qiao Abdullah MAsiri Khalid AAlamry Kui Zhang | 2020 | Journal of Materials Science & Technology2020，47，15： | 1 |
| 2 | Efficacy and safety of Weichang’an pill(胃肠安丸)combined with Western Medicine on gastrointestinal diseases:a systematic review and Meta-analysis显示文摘OBJECTIVE:To systematically evaluate the efficacy and safety of Weichang’an pill(胃肠安丸,WCA)combined with Western Medicine(WM)for the treatment of gastrointestinal diseases.METHODS:Eight databases,including China National Knowledge Infrastructure Database,Wanfang Data,China Science and Technology Journal Database,SinoMed,PubMed,Web of Science,Cochrane Library,and Embase,were searched for randomized controlled trials(RCTs)of WCA from inception to 30 September 2021.We independently screened the literature,extracted data,and then evaluated the bias risk,effectiveness,safety,and other indicators of the included articles.RESULTS:A total of 33 RCTs were included in this study with 3368 patients.After analysis,it was found that WCA combined with WM could effectively prevent and treat antibiotic-associated gastrointestinal reaction,functional dyspepsia(FD),irritable bowel syndrome,rotavirus diarrhea(RVD),and ulcerative colitis(UC);no serious adverse reactions occurred.Moreover,compared with the control group,the experimental group showed significantly improved symptoms and some biochemical parameters.CONCLUSIONS:WCA combined with WM for the treatment of gastrointestinal diseases had better clinical efficacy than the control group,without serious adverse reactions.Notably,in the treatment of FD,RVD,and UC,WCA improved clinical symptoms and biochemical indicator expression.Nevertheless,owing to the restricted quality and quantity of the literature,the results need to be further studied using high-quality RCTs. | WANG Jiabao ZHANG Lishuang NIU Baihan YU Yajun YANG Fengwen MIAO Lin CHAI Lijuan DING Xinya SUN Yingjie WANG Yujing WANG Lin ZHANG Han WANG Yi LI Lin | 2023 | Journal of Traditional Chinese Medicine2023，43，6： | 0 |
| 3 | Recent advances and applications of single atom catalysts based electrochemical sensors显示文摘Single atom catalysts(SACs)have attracted considerable attention due to their unique structures and excellent catalytic performance,especially in the area of catalysis science and energy conversion and storage.In recent years,SACs have emerged as a new type of sensing material for constructing electrochemical sensors(ECSs),presenting excellent sensitivity,selectivity,and stability.Herein,we review the recent advances of SACs in electrochemical sensing and discuss the status quo of current SAC-based ECSs.Specifically,the fundamentals of SAC-based ECSs are outlined,including the involved central metal atoms and various supports of SACs in this field,the detection mechanisms,and improving strategies of SAC-based ECSs.Moreover,the important applications of SAC-based ECSs are listed and classified,covering the detection of reactive oxygen and nitrogen species,environmental pollutants,disease biomarkers,and pharmaceuticals.Last,based on abundant reported cases,the current conundrums of SAC-based ECSs are summarized,and the prediction of their future developing trends is also put forward. | Mingyue Wang Mingfu Ye Jieyue Wang Yong Xu Zhendong Wang Xinyue Tong Xinya Han Kui Zhang Wenhai Wang Konglin Wu Xianwen Wei | 2024 | Nano Research2024，17，4： | 0 |
| 4 | 畅享自然——让老年人乐享幸福生活的生态社区公园设计显示文摘为了更好地照顾老年人,护理模式正在一步步由家庭护理向社区护理转变。该项目以自然恢复、低影响发展、自我维持的生态社区为设计理念,旨在创造一个健康舒适的户外空间,为老年人提供互动、娱乐和教育服务,加强老年人与家人之间的联系,并完善社区内外的社交网络。项目地址位于安徽省合肥市中心的仙桥社区。该社区占地0.46平方公里,有6个相对独立的居民区。原有社区景观设计陈旧,建筑密度高,仅有一个公共广场和一个袖珍公园,区域内居民很少有接触到绿色和自然的机会。 | Peng Chen Yichen Lou Kun Qian Zhengwei Xing Yunxin Han Wenjun Liu Hongbo Chen Wenqi Chen Xinmiao Zhu Lang Qin Xueying Liu Yu Leng Xinya Hu Suheng Yao | 2023 | 工业设计2023，，9： | 0 |
