| 1 | Sandwich-Like Fe&TiO2@C Nanocomposites Derived from MXene/Fe-MOFs Hybrids for Electromagnetic Absorption显示文摘Electromagnetic pollution has been causing a series of problems in people’s life,and electromagnetic absorbers with lightweight and broad absorbing bandwidth properties are widely desired.In this work,novel sandwich-like 2D laminated Fe&TiO2 nanoparticles@C nanocomposites were rationally designed and successfully developed from the MXene–MOFs hybrids.The formation of Fe and rutile-TiO2 nanoparticles sandwiched by the two-dimensional carbon nanosheets provided strong electromagnetic energy attenuation and good impedance matching for electromagnetic wave(EMW)absorption.As expected,the nanocomposites achieved a broad effective absorption bandwidth of 6.5 GHz at a thickness of only 1.6 mm and the minimum reflection loss(RL)value of−51.8 dB at 6.6 GHz with a thickness of 3 mm.This work not only provides a good design and fabricating concept for the laminated metal and functional nanoparticles@C nanocomposites with good EMW absorption,but also offers an important guideline to fabricate various two-dimensional nanocomposites derived from the MXene precursors. | Baiwen Deng Zhen Xiang Juan Xiong Zhicheng Liu Lunzhou Yu Wei Lu | 2020 | Nano-Micro Letters2020，12，4： | 16 |
| 2 | Lotus Leaf‑Derived Gradient Hierarchical Porous C/MoS2 Morphology Genetic Composites with Wideband and Tunable Electromagnetic Absorption Performance显示文摘Inspired by the nature,lotus leaf-derived gradient hierarchical porous C/MoS2 morphology genetic composites(GHPCM)were successfully fabricated through an in situ strategy.The biological microstructure of lotus leaf was well preserved after treatment.Different pores with gradient pore sizes ranging from 300 to 5μm were hierarchically distributed in the composites.In addition,the surface states of lotus leaf resulted in the Janus-like morphologies of MoS2.The GHPCM exhibit excellent electromagnetic wave absorption performance,with the minimum reflection loss of−50.1 dB at a thickness of 2.4 mm and the maximum effective bandwidth of 6.0 GHz at a thickness of 2.2 mm.The outstanding performance could be attributed to the synergy of conductive loss,polarization loss,and impedance matching.In particularly,we provided a brand-new dielectric sum-quotient model to analyze the electromagnetic performance of the non-magnetic material system.It suggests that the specific sum and quotient of permittivity are the key to keep reflection loss below−10 dB within a certain frequency range.Furthermore,based on the concept of material genetic engineering,the dielectric constant could be taken into account to seek for suitable materials with designable electromagnetic absorption performance. | Fei Pan Zhicheng Liu Baiwen Deng Yanyan Dong Xiaojie Zhu Chuang Huang Wei Lu | 2021 | Nano-Micro Letters2021，13，3： | 9 |
| 3 | Catalytic conversion of lignocellulosic biomass into chemicals and fuels显示文摘In the search of alternative resources to make commodity chemicals and transportation fuels for a low carbon future,lignocellulosic biomass with over 180-billion-ton annual production rate has been identified as a promising feedstock.This review focuses on the state-of-the-art catalytic transformation of lignocellulosic biomass into value-added chemicals and fuels.Following a brief introduction on the structure,major resources and pretreatment methods of lignocellulosic biomass,the catalytic conversion of three main components,i.e.,cellulose,hemicellulose and lignin,into various compounds are comprehensively discussed.Either in separate steps or in one-pot,cellulose and hemicellulose are hydrolyzed into sugars and upgraded into oxygen-containing chemicals such as 5-HMF,furfural,polyols,and organic acids,or even nitrogen-containing chemicals such as amino acids.On the other hand,lignin is first depolymerized into phenols,catechols,guaiacols,aldehydes and ketones,and then further transformed into hydrocarbon fuels,bioplastic precursors and bioactive compounds.The review then introduces the transformations of whole biomass via catalytic gasification,catalytic pyrolysis,as well as emerging strategies.Finally,opportunities,challenges and prospective of woody biomass valorization are highlighted. | Weiping Deng Yunchao Feng Jie Fu Haiwei Guo Yong Guo Buxing Han Zhicheng Jiang Lingzhao Kong Changzhi Li Haichao Liu Phuc T.T.Nguyen Puning Ren Feng Wang Shuai Wang Yanqin Wang Ye Wang Sie Shing Wong Kai Yan Ning Yan Xiaofei Yang Yuanbao Zhang Zhanrong Zhang Xianhai Zeng Hui Zhou | 2023 | Green Energy & Environment2023，8，1： | 6 |

| 6 | Advancements in understanding mechanisms of hepatocellular carcinoma radiosensitivity:A comprehensive review显示文摘Primary liver cancer is a significant health problem worldwide.Hepatocellular carcinoma(HCC)is the main pathological type of primary liver cancer,accounting for 75%-85%of cases.In recent years,radiotherapy has become an emerging treatment for HCC and is effective for various stages of HCC.However,radiosensitivity of liver cancer cells has a significant effect on the efficacy of radiotherapy and is regulated by various factors.How to increase radiosensitivity and improve the therapeutic effects of radiotherapy require further exploration.This review summarizes the recent research progress on the mechanisms affecting sensitivity to radiotherapy,including epigenetics,transportation and metabolism,regulated cell death pathways,the microenvironment,and redox status,as well as the effect of nanoparticles on the radiosensitivity of liver cancer.It is expected to provide more effective strategies and methods for clinical treatment of liver cancer by radiotherapy. | Gaoyuan Yang Huamei Yan Yongchang Tang Feng Yuan Mingbo Cao Yupeng Ren Yuxuan Li Zhiwei He Xiaorui Su Zhicheng Yao Meihai Deng | 2023 | Chinese Journal of Cancer Research2023，35，3： | 1 |
| 7 | A study of plasmon-driven catalytic 4-NBT to DMAB in the dry film by using spatial Raman mapping spectroscopy显示文摘Plasmon-driven catalytic reaction(PDCR)as a part of photocatalysis has attracted immense attention.Due to the collective oscillation of free electrons at the surface of metallic nanostructures,the charge distributions store energy from the incident light that could transfer energy to molecules that promote photocatalysis.As an environment-friendly and green photocatalysis process,PDCR illustrates a brilliant future.In this study,the PDCR efficiency of photo-reducing 4-nitro-benzenthiol(4-NBT)dry film to p,p'-dimercaptoazobenzene(DMAB)in ambient conditions has been studied by using Ag nanodiscs(NDs)and Ag nanoparticles(NPs)as catalysts.The distribution of catalytic efficiency of 4-NBT to DMAB using an individual Ag ND catalyst has been illustrated using spatial Raman mapping.The result is direct evidence that the PDCR efficiency has a positive correlation with plasmon-induced electromagnetic field intensity.Additionally,time-dependent surface-enhanced Raman scattering(SERS)experiments reveal that the PDCR of 4-NBT to DMAB is reciprocal.The discovery in this research will aid to improve the PDCR performance and modulate the catalysis reaction for a high reduction of 4-NBT in industrial. | Yansheng Liu Junpeng Deng Zhicheng Jin Tianxing Liu Jin Zhou Feng Luo Guofu Wang | 2022 | Nano Research2022，15，7： | 0 |

| 10 | Regulating the microenvironment with nanomaterials:Potential strategies to ameliorate COVID-19显示文摘COVID-19,caused by SARS-CoV-2,has resulted in serious economic and health burdens.Current treatments remain inadequate to extinguish the epidemic,and efficient therapeutic approaches for COVID-19 are urgently being sought.Interestingly,accumulating evidence suggests that microenvironmental disorder plays an important role in the progression of COVID-19 in patients.In addition,recent advances in nanomaterial technologies provide promising opportunities for alleviating the altered homeostasis induced by a viral infection,providing new insight into COVID-19 treatment.Most literature reviews focus only on certain aspects of microenvironment alterations and fail to provide a comprehensive overview of the changes in homeostasis in COVID-19 patients.To fill this gap,this review systematically discusses alterations of homeostasis in COVID-19 patients and potential mechanisms.Next,advances in nanotechnology-based strategies for promoting homeostasis restoration are summarized.Finally,we discuss the challenges and prospects of using nanomaterials for COVID-19 management.This review provides a new strategy and insights into treating COVID-19 and other diseases associated with microenvironment disorders. | Zhicheng Liu Zhuolei Han Xin Jin Jusung An Jaewon Kim Wenting Chen Jong Seung Kim Ji Zheng Jun Deng | 2023 | Acta Pharmaceutica Sinica B2023，13，9： | 0 |
| 11 | Axial and radial electromagnetic-vibration characteristics of converter transformer windings under current harmonics显示文摘The winding current harmonic content of converter transformer in operation is rich.However,affected by harmonics,the radial vibration characteristics are quite different from the power transformer,structural loosening and deformation caused by winding vibration are more prominent.Therefore,in view of the influence of current harmonics on axial and radial vibrations,this study builds a 3D winding electromagnetic vibration finite element simulation model,analyses the components and contents of current harmonics,compares the leakage flux and vibration distribution under the fundamental,harmonic and superimposed currents.The correlation relationship between the harmonic components and axial and radial vibration characteristics is obtained,and the vibration measurement test of±800 kV converter transformer in operation is carried out to verify the correctness of the analysis method.The results show that the winding radial vibration amplitude will exceed the axial vibration affected by harmonics.More importantly,under the superposition of the fundamental,5th and 7th harmonic current,the vibration contribution of the converter transformer tank is mainly radial vibration,and the vibration dominant frequency is shifted from 100 Hz under the fundamental current to 400 Hz. | Peiyu Jiang Zhanlong Zhang Zijian Dong Yu Yang Zhicheng Pan Jun Deng | 2023 | High Voltage2023，8，3： | 0 |
| 12 | Multi-junction cascaded vertical-cavity surface-emitting laser with a high power conversion efficiency of 74%显示文摘High electro-optical conversion efficiency is one of the most distinctive features of semiconductor lasers as compared to other types of lasers.Its further increase remains a significant objective.Further enhancing the efficiency of edgeemitting lasers(EEL),which represent the highest efficiency among semiconductor lasers at present,is challenging.The efficiency of vertical cavity surface emitting lasers(VCSELs)has always been relatively low compared to EEL.This paper,combining modeling with experiments,demonstrates the potential of multi-junction cascaded VCSELs to achieve high efficiency beyond that of EELs,our simulations show,that a 20-junction VCSEL can achieve an efficiency of more than 88%at room temperature.We fabricated VCSEL devices with different numbers of junctions and compared their energy efficiency.15-junction VCSELs achieved a maximum efficiency of 74%at room temperature under nanosecond driving current,the corresponding differential quantum efficiency exceeds 1100%,being the largest electro-optical conversion efficiency and differential quantum efficiency reported until now for VCSELs. | Yao Xiao Jun Wang Heng Liu Pei Miao Yudan Gou Zhicheng Zhang Guoliang Deng Shouhuan Zhou | 2024 | Light(Science & Applications)2024，13，3： | 0 |
| 13 | Efficacy of early prone or lateral positioning in patients with severe COVID-19:a single-center prospective cohort显示文摘Background:Position intervention has been shown to improve oxygenation,but its role in non-invasively ventilated patients with severe COVID-19 has not been assessed.The objective of this study was to investigate the efficacy of early position intervention on non-invasively ventilated patients with severe COVID-19.Methods:This was a single-center,prospective observational study in consecutive patients with severe COVID-19 managed in a provisional ICU at Renmin Hospital of Wuhan University from 31 January to 15 February 2020.Patients with chest CT showing exudation or consolidation in bilateral peripheral and posterior parts of the lungs were included.Early position intervention(prone or lateral)was commenced for>4 hours daily for 10 days in these patients,while others received standard care.Results:The baseline parameters were comparable between the position intervention group(n=17)and the standard care group(n=35).Position intervention was well-tolerated and increased cumulative adjusted mean difference of SpO_(2)/FiO_(2)(409,95%CI 86 to 733)and ROX index(26,95%CI 9 to 43)with decreased Borg scale(−9,95%CI−15 to−3)during the first 7 days.It also facilitated absorption of lung lesions and reduced the proportion of patients with high National Early Warning Score 2(≥7)on days 7 and 14,with a trend toward faster clinical improvement.Virus shedding and length of hospital stay were comparable between the two groups.Conclusions:This study provides the first evidence for improved oxygenation and lung lesion absorption using early position intervention in non-invasively ventilated patients with severe COVID-19,and warrants further randomized trials. | Zhong Ni Kaige Wang Ting Wang Yuenan Ni Wei Huang Ping Zhu Tao Fan Ye Wang Bo Wang Jun Deng Zhicheng Qian Jiasheng Liu Wenhao Cai Shanling Xu Yu Du Gang Wang Zongan Liang Weimin Li Jianfei Luo Fengming Luo Dan Liu | 2020 | Precision Clinical Medicine2020，3，4： | 0 |
