| 1 | Efficient aerobic oxidation of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid on Ru/C catalysts显示文摘2,5-Furandicarboxylic(FDCA) is a potential substitute for petroleum-derived terephthalic acid, and aerobic oxidation of5-hydroxymethylfurfural(HMF) provides an efficient route to synthesis of FDCA. On an activated carbon supported ruthenium(Ru/C) catalyst(with 5 wt% Ru loading), HMF was readily oxidized to FDCA in a high yield of 97.3% at 383 K and 1.0 MPa O_2 in the presence of Mg(OH)_2 as base additive. Ru/C was superior to Pt/C and Pd/C and also other supported Ru catalysts with similar sizes of metal nanoparticles(1–2 nm). The Ru/C catalysts were stable and recyclable, and their efficiency in the formation of FDCA increased with Ru loadings examined in the range of 0.5 wt%–5.0 wt%. Based on the kinetic studies including the effects of reaction time, reaction temperature, O_2 pressure, on the oxidation of HMF to FDCA on Ru/C, it was confirmed that the oxidation of HMF to FDCA proceeds involving the primary oxidation of HMF to 2,5-diformylfuran(DFF) intermediate, and its sequential oxidation to 5-formyl-2-furancarboxylic acid(FFCA) and ultimately to FDCA, in which the oxidation of FFCA to FDCA is the rate-determining step and dictates the overall formation rate of FDCA. This study provides directions towards efficient synthesis of FDCA from HMF, for example, by designing novel catalysts more efficient for the involved oxidation step of FFCA to FDCA. | Lufan Zheng Junqi Zhao Zexue Du Baoning Zong Haichao Liu | 2017 | Science China Chemistry2017,60,7: | 8 |

| 3 | Optical wafer defect inspection at the 10 nm technology node and beyond显示文摘The growing demand for electronic devices, smart devices, and the Internet of Things constitutes the primary driving force for marching down the path of decreased critical dimension and increased circuit intricacy of integrated circuits. However, as sub-10 nm high-volume manufacturing is becoming the mainstream, there is greater awareness that defects introduced by original equipment manufacturer components impact yield and manufacturing costs. The identification, positioning, and classification of these defects, including random particles and systematic defects, are becoming more and more challenging at the 10 nm node and beyond.Very recently, the combination of conventional optical defect inspection with emerging techniques such as nanophotonics, optical vortices, computational imaging, quantitative phase imaging, and deep learning is giving the field a new possibility. Hence, it is extremely necessary to make a thorough review for disclosing new perspectives and exciting trends, on the foundation of former great reviews in the field of defect inspection methods. In this article, we give a comprehensive review of the emerging topics in the past decade with a focus on three specific areas:(a) the defect detectability evaluation,(b) the diverse optical inspection systems,and(c) the post-processing algorithms. We hope, this work can be of importance to both new entrants in the field and people who are seeking to use it in interdisciplinary work. | Jinlong Zhu Jiamin Liu Tianlai Xu Shuai Yuan Zexu Zhang Hao Jiang Honggang Gu Renjie Zhou Shiyuan Liu | 2022 | International Journal of Extreme Manufacturing2022,4,3: | 4 |

| 5 | One-step floating conversion of biomass into highly graphitized and continuous carbon nanotube yarns显示文摘The rapid growth of the demand for carbon nanotubes(CNTs) has greatly promoted their large-scale synthesis and development. However,the continuous production of CNT fibers by floating catalyst chemical vapor deposition(FCCVD) requires a large amount of non-renewable carbon sources. Here, the continuous production of highly graphitized CNT yarns from biomass tannic acid(TA) is reported. The chelation of TA and catalyst promotes the rapid cracking of biomass into carbon source gas, and the pyrolysis cracking produces the reducing gas, which solves the problems of the continuous production of CNT yarns using biomass. Through simple twisting, the mechanical strength of CNT yarn can reach 886 ± 46 MPa, and the electrical conductivity and graphitization(IG/ID) can reach 2 × 10^(5)S m^(-1)and 6.3, respectively. This work presents a promising solution for the continuous preparation of CNT yarns based on green raw material. | Gongxun Zhai Qianqian Wang Fuyao Liu Zexu Hu Chao Jia Dengxin Li Hengxue Xiang Meifang Zhu | 2023 | Green Energy & Environment2023,8,6: | 0 |
| 6 | A green route for hydrogen production from alkaline thermal treatment(ATT)of biomass with carbon storage显示文摘Hydrogen,a green energy carrier,is one of the most promising energy sources.However,it is currently mainly produced from depleting fossil fuels with high carbon emissions,which has serious negative effects on the economy and environment.To address this issue,sustainable hydrogen production from bio-energy with carbon capture and storage(HyBECCS)is an ideal technology to reduce global carbon emissions while meeting energy demand.This review presents an overview of the latest progress in alkaline thermal treatment(ATT)of biomass for hydrogen production with carbon storage,especially focusing on the technical characteristics and related challenges from an industrial application perspective.Additionally,the roles of alkali and catalyst in the ATT process are critically discussed,and several aspects that have great influences on the ATT process,such as biomass types,reaction parameters,and reactors,are expounded.Finally,the potential solutions to the general challenges and obstacles to the future industrial-scale application of ATT of biomass for hydrogen production are proposed. | Guojie Liu Zexue Du Houfang Lu Jianli Zeng Kejing Wu Bin Liang | 2023 | Carbon Resources Conversion2023,6,4: | 0 |
| 7 | Synthetic apomixis enables stable transgenerational transmission of heterotic phenotypes in hybrid rice显示文摘In hybrid plants,heterosis often produces large,vigorous plants with high yields;however,hybrid seeds are generated by costly and laborious crosses of inbred parents.Apomixis,in which a plant produces a clone of itself via asexual reproduction through seeds,may produce another revolution in plant biology.Recently,synthetic apomixis enabled clonal reproduction of F_(1) hybrids through seeds in rice(Oryza sativa),but the inheritance of the synthetic apomixis trait and superior heterotic phenotypes across generations remained unclear.Here,we propagated clonal plants to the T_(4) generation and investigated their genetic and molecular stability at each generation.By analyzing agronomic traits,as well as the genome,methylome,transcriptome,and allele-specific transcriptome,we showed that the descendant clonal plants remained stable.Unexpectedly,in addition to normal clonal seeds,the plants also produced a few aneuploids that had eliminated large genomic segments in each generation.Despite the identification of rare aneuploids,the observation that the synthetic apomixis trait is stably transmitted through multiple generations helps confirm the feasibility of using apomixis in the future. | Chaolei Liu Zexue He Yan Zhang Fengyue Hu Mengqi Li Qing Liu Yong Huang Jian Wang Wenli Zhang Chun Wang Kejian Wang | 2023 | Plant Communications2023,4,2: | 0 |
| 8 | Application of eDNA Metabarcoding for Detecting Anura in North China显示文摘eDNA metabarcoding is an advanced method formonitoring biodiversityproposed in recent years.By analyzing DNA in water,soil and sediment samples,the technology obtains species distribution and population quantity information.It was found that macrobarcode technology is more accurate than the traditional method in measuring the species richness of some groups.In Europe,America and South America,the relia bility of this technology in monitoring amphibian diversity in the wild was studied,and it was found to be better than traditional biodiversity monitoring methods in detecting species diversity.At present,amphibian monitoring mainly depends on various traditional methods,such as transects,drift fence traps,artificial shelters and mark-recapture.These monitoring techniques have many shortcomings,such as low accuracy and strong subjectivity of study results.These technologies have poor effects on rare,invasive and endangered species with strong concealment ability,low density and strong seasonality and are difficult to implement in sites inaccessible to people.Traditional monitoring technology also requires considerable investment of human and material resources,and the economic cost is relatively high,while eDNA metabarcoding ismore efficient and less costly,so it is important to use eDNA meta barcoding in amphibian monitoring in China.In this study,the eDNA meta barcoding and traditional line transect method(TLTM)were used to study the characteristics of the two methods in the Beijing-Tianjin-Hebeiregion.Repeated samplingwas conducted on 58 waterbodies in July 2019 and June 2020.After sequencing the samples using highthroughput sequencing technology,the differences between metabarcoding and commonly used TLTM surveys in detecting the diversity of four amphibians in North China were assessed.Our results showed that eDNA meta barcoding is more sensitive to the detection of the four amphibian species in the sampling area,and the combined use of eDNA metabarcoding and TLTM can improve the survey results of amphibians in the survey area to the greatest extent.In addition,in the process of species classification and identification of metabarcoding results,7 species of reptiles were detected,indicating that eDNA metabarcoding is also useful to detect reptiles.The results of this study indicate that metabarcoding in combination with TLTM can accurately estimate the diversityof amphibians in a short-term survey in North China and is also useful in reptile species detection. | Wenhao LI Mingshuo QIN Xianglei HOU Jiaqi ZHANG Siqi WANG Yu LI Zexu LUO Teng DENG Tianjian SONG Chunxia XU Xuan LIU Xuyu WANG Yiming LI | 2022 | Asian Herpetological Research2022,13,4: | 0 |
| 9 | Hierarchically porous Cu current collector with lithiophilic CuxO interphase towards high-performance lithium metal batteries显示文摘Lithium metal is one of the most promising anode materials for next-generation electrochemical energy storage due to low electrochemical potential and high specific capacity.However,large volume change and uncontrollable formation of lithium dendrite during cycling severely hinder the practical application of rechargeable Li metal batteries.Herein,we report a hierarchically porous Cu covered with lithiophilic CuxO(HPCu-CuxO) via femtosecond laser strategy in about 2 min as current collector for highperformance Li metal batteries.With precisely tunable pore volume and depth as well as lithiophilic CuxO interphase,the HPCu-CuxO not only guides homogeneous Li nucleation,resulting in a smooth and dendrite-free lithium surface,but also provides space to alleviate the volume expansion of Li metal anode,achieving excellent structure stability.Consequently,highly stable Coulombic efficiency and ultralow overpotential of 15 mV even up to 1000 h were achieved at the current density of 1 mA cm^(-2).Moreover,the resultant Li@HPCu-CuxO//LiFePO_(4) full battery delivered outstanding cycle stability and rate capability.These results offer a pathway toward high-energy-density and safe rechargeable Li metal batteries. | Yaya Wang Zexu Zhao Wei Zeng Xingbo Liu Lei Wang Jian Zhu Bingan Lu | 2021 | Journal of Energy Chemistry2021,30,7: | 0 |
