1Carbon nanosheets derived from reconstructed lignin for potassium and sodium storage with low voltage hysteresis显示文摘Lignin is the second most abundant and the only nature polymer rich in aromatic units.Although aromatic-unit-rich precursors often yield soft carbon after carbonization,the side chains in lignin crosslink with the aromatic units and form a rigid three-dimensional(3D)structure which eventually leads to hard carbons.Through a graphene oxide-catalyzed decomposition and repolymerization process,we successfully reconstructed lignin by partially tailoring the side chains.Compared to directly carbonized lignin,the carbonized reconstructed lignin possesses significantly fewer defects,86%fewer oxygen-functionalities,82%fewer micropores,and narrower interlayer space.These parameters can be tuned by the amount of catalysts(graphene oxide).When tested as anode for K-ion and Na-ion batteries,the carbonized reconstructed lignin delivers notably higher capacity at low-potential range(especially for Na-storage),shows much-improved performance at high current density,and most importantly,reduces voltage hysteresis between discharge and charge process by more than 50%,which is critical to the energy efficiency of the energy storage system.Our study reveals that the voltage hysteresis in K-storage is much severer than that in Na-storage for all samples.For practical K-ion battery applications,the voltage hysteresis deserves more attention in future electrode materials design and the reconstruct ion strategy introduced in this work provides potential low-cost solution.Keren Jiang Xuehai Tan Shengli Zhai Ken Cadien Zhi Li 2021Nano Research2021,14,12:2

6Defining honeybee subspecies in an evolutionary context warrants strategized conservation显示文摘Despite the urgent need for conservation consideration,strategic action plans for the preservation of the Asian honeybee,Apis cerana Fabricius,1793,remain lacking.Both the convergent and divergent adaptations of this widespread insect have led to confusing phenotypical traits and inconsistent infraspecific taxonomy.Unclear subspecies boundaries pose a significant challenge to honeybee conservation efforts,as it is difficult to effectively prioritize conservation targets without a clear understanding of subspecies identities.Here,we investigated genome variations in 362 worker bees representing almost all populations of mainland A.cerana to understand how evolution has shaped its population structure.Whole-genome single nucleotide polymorphisms(SNPs)based on nuclear sequences revealed eight putative subspecies,with all seven peripheral subspecies exhibiting mutually exclusive monophyly and distinct genetic divergence from the widespread central subspecies.Our results demonstrated that most classic morphological traits,including body size,were related to the climatic variables of the local habitats and did not reflect the true evolutionary history of the organism.Thus,such morphological traits were not suitable for subspecific delineation.Conversely,wing vein characters showed relative independence to the environment and supported the subspecies boundaries inferred from nuclear genomes.Mitochondrial phylogeny further indicated that the present subspecies structure was a result of multiple waves of population divergence from a common ancestor.Based on our findings,we propose that criteria for subspecies delineation should be based on evolutionary independence,trait distinction,and geographic isolation.We formally defined and described eight subspecies of mainland A.cerana.Elucidation of the evolutionary history and subspecies boundaries enables a customized conservation strategy for both widespread and endemic honeybee conservation units,guiding colony introduction and breeding.Lifei Qiu Jiangxing Dong Xingan Li Sajad HParey Ken Tan Michael Orr Aquib Majeed Xue Zhang Shiqi Luo Xuguo Zhou Chaodong Zhu Ting Ji Qingsheng Niu Shanlin Liu Xin Zhou 2023Zoological Research2023,44,3:1

10Translational plasma stomatology:applications of cold atmospheric plasmas in dentistry and their extension显示文摘In recent years,translational plasma medicine(TPM),as a novel application area of plasmas,has attracted much attention of experts from both academic and clinical fields.State-of-the-art of the lab-scale research and clinical trials of the cold atmospheric plasmas(CAPs)in the stomatology are reviewed in detail from the direct and indirect applications of the CAPs.Based on the discussions concerning the relationship between the plasma stomatology and the plasma medicine,it is indicated that it would be an important reference for promoting the TPM starting from the fundamental and application studies in the field of dentistry,which is also one of the most three promising application fields of plasma medicine.He-Ping Li Xiao-Fei Zhang Xiao-Ming Zhu Miao Zheng Shu-Fang Liu Xuan Qi Kai-Peng Wang Jian Chen Xiao-Qing Xi Jian-Guo Tan Kostya(Ken)Ostrikov 2017High Voltage2017,2,3:1

18Safety and efficacy of thalidomide in patients with transfusiondependentβ-thalassemia:a randomized clinical trial显示文摘Thalidomide inducesγ-globin expression in erythroid progenitor cells,but its efficacy on patients with transfusion-dependentβ-thalassemia(TDT)remains unclear.In this phase 2,multi-center,randomized,double-blind clinical trial,we aimed to determine the safety and efficacy of thalidomide in TDT patients.A hundred patients of 14 years or older were randomly assigned to receive placebo or thalidomide for 12 weeks,followed by an extension phase of at least 36 weeks.The primary endpoint was the change of hemoglobin(Hb)level in the patients.The secondary endpoints included the red blood cell(RBC)units transfused and adverse effects.In the placebo-controlled period,Hb concentrations in patients treated with thalidomide achieved a median elevation of 14.0(range,2.5 to 37.5)g/L,whereas Hb in patients treated with placebo did not significantly change.Within the 12 weeks,the mean RBC transfusion volume for patients treated with thalidomide and placebo was 5.4±5.0 U and 10.3±6.4 U,respectively(P<0.001).Adverse events of drowsiness,dizziness,fatigue,pyrexia,sore throat,and rash were more common with thalidomide than placebo.In the extension phase,treatment with thalidomide for 24 weeks resulted in a sustainable increase in Hb concentrations which reached 104.9±19.0 g/L,without blood transfusion.Significant increase in Hb concentration and reduction in RBC transfusions were associated with nonβ0/β0 and HBS1L-MYB(rs9399137 C/T,C/C;rs4895441 A/G,G/G)genotypes.These results demonstrated that thalidomide is effective in patients with TDT.Jiang-Ming Chen Wei-Jian Zhu Jie Liu Gui-Zhen Wang Xiao-Qin Chen Yun Tan Wei-Wei Xu Li-Wei Qu Jin-Yan Li Huan-Ju Yang Lan Huang Ning Cai Wei-Da Wang Ken Huang Jian-Quan Xu Guo-Hui Li Sheng He Tian-Ying Luo Yi Huang Song-Hua Liu Wen-Qiang Wu Qi-Yang Lu Mei-Guang Zhou Shu-Ying Chen Rong-Lan Li Mei-Ling Hu Ying Huang Jin-Hua Wei Jun-Min Li Sai-Juan Chen Guang-Biao Zhou 2021Signal Transduction and Targeted Therapy2021,6,12:1
