| 1 | Review of Ultraviolet Non-Line-of-Sight Communication显示文摘With rapid advances of solar blind ultraviolet LED and ultraviolet detecting technology in recent years, ultraviolet communication gradually becomes a research hotspot due to its inherent advantages: low solar background noise, non-line-of-sight(NLOS) and good secrecy. The strong scattering characteristics in atmospheric render ultraviolet waveband the ideal choice for achieving NLOS optical communication. This paper reviews the research history and status of ultraviolet communication both in China and abroad, and especially introduces three main issues of ultraviolet communication: channel model, system analysis and design, light sources and detectors. For each aspect, current open issues and prospective research directions are analyzed. | Renzhi Yuan Jianshe Ma | 2016 | China Communications2016，13，6： | 22 |
| 2 | 2D Layered Double Hydroxide Nanosheets and Their Derivatives Toward E cient Oxygen Evolution Reaction显示文摘Layered double hydroxides(LDHs)have attracted tremendous research interest in widely spreading applications.Most notably,transition-metal-bearing LDHs are expected to serve as highly active electrocatalysts for oxygen evolution reaction(OER)due to their layered structure combined with versatile com-positions.Furthermore,reducing the thickness of platelet LDH crystals to nanometer or even molecular scale via cleavage or delamination provides an important clue to enhance the activity.In this review,recent progresses on rational design of LDH nanosheets are reviewed,including direct synthesis via traditional coprecipitation,homogeneous precipitation,and newly developed topochemical oxidation as well as chemical exfoliation of parent LDH crystals.In addition,diverse strategies are introduced to modulate their electrochemical activity by tuning the composition of host metal cations and intercalated counter-anions,and incorporating dopants,cavi-ties,and single atoms.In particular,hybridizing LDHs with conductive components or in situ growing them on conductive substrates to produce freestanding electrodes can further enhance their intrinsic catalytic activity.A brief discussion on future research directions and prospects is also summarized. | Xueyi Lu Hairong Xue Hao Gong Mingjun Bai Daiming Tang Renzhi Ma Takayoshi Sasaki | 2020 | Nano-Micro Letters2020，12，7： | 8 |
| 3 | Folate receptor-mediated boron-10 containing carbon nanoparticles as potential delivery vehicles for boron neutron capture therapy of nonfunctional pituitary adenomas显示文摘Invasive nonfunctional pituitary adenomas(NFPAs) are difficult to completely resect and often develop tumor recurrence after initial surgery.Currently,no medications are clinically effective in the control of NFPA.Although radiation therapy and radiosurgery are useful to prevent tumor regrowth,they are frequently withheld because of severe complications.Boron neutron capture therapy(BNCT) is a binary radiotherapy that selectively and maximally damages tumor cells without harming the surrounding normal tissue.Folate receptor(FR)-targeted boron-10 containing carbon nanoparticles is a novel boron delivery agent that can be selectively taken up by FR-expressing cells via FR-mediated endocytosis.In this study,FR-targeted boron-10 containing carbon nanoparticles were selectively taken up by NFPAs cells expressing FR but not other types of non-FR expressing pituitary adenomas.After incubation with boron-10 containing carbon nanoparticles and following irradiation with thermal neutrons,the cell viability of NFPAs was significantly decreased,while apoptotic cells were simultaneously increased.However,cells administered the same dose of FR-targeted boron-10 containing carbon nanoparticles without neutron irradiation or received the same neutron irradiation alone did not show significant decrease in cell viability or increase in apoptotic cells.The expression of Bcl-2 was down-regulated and the expression of Bax was up-regulated in NFPAs after treatment with FR-mediated BNCT.In conclusion,FR-targeted boron-10 containing carbon nanoparticles may be an ideal delivery system of boron to NFPAs cells for BNCT.Furthermore,our study also provides a novel insight into therapeutic strategies for invasive NFPA refractory to conventional therapy,while exploring these new applications of BNCT for tumors,especially benign tumors. | DAI CongXin CAI Feng HWANG Kuo Chu ZHOU YongMao ZHANG ZiZhu LIU XiaoHai MA SiHai YANG YaKun YAO Yong FENG Ming BAO XinJie LI GuiLin WEI JunJi JIAO YongHui WEI ZhenQing MA WenBin WANG RenZhi | 2013 | Science China(Life Sciences)2013，56，2： | 8 |

| 5 | Engineering of carbon and other protective coating layers for stabilizing silicon anode materials显示文摘Silicon(Si)has been attracting extensive attention for rechargeable lithium(Li)‐ion batteries due to its high theoretical capacity and low potential vs Li/Li+.However,it remains challenging and problematic to stabilize the Si materials during electrochemical cycling because of the huge volume expansion,which results in losing electric contact and pulverization of Si particles.Consequently,the Si anode materials generally suffer from poor cycling,poor rate performance,and low coulomb efficiency,preventing them from practical applications.Up‐to‐date,there are numerous reports on the engineering of Si anode materials at microscale and nanoscale with significantly improved electrochemical performances.In this review,we will concentrate on various precisely designed protective layers for silicon‐based materials,including carbon layers,inorganic layers,and conductive polymer protective layer.First,we briefly introduced the alloying and failure mechanism of Si as anode materials upon electrochemical reactions.Following that,representative cases have been introduced and summarized to illustrate the purpose and advancement of protective coating layers,for instance,to alleviate pulverization and improve conductivity caused by volume expansion of Si particles during charge/discharge process,and maintain the surface stability of Si particles to form a stable solid‐electrolyte interphase layer.At last,possible strategies on the protective coating layer for stabilizing silicon anode materials that can be applied in the future have been indicated. | Fenglin Wang Gen Chen Ning Zhang Xiaohe Liu Renzhi Ma | 2019 | Carbon Energy2019，1，2： | 3 |
| 6 | Recent progress in functionalized layered double hydroxides and their application in efficient electrocatalytic water oxidation显示文摘Layered double hydroxides (LDHs), a class of anionic clays consisting of brucite-like host layers and interlayer anions, have been widely investigated in the last decade due to their promising applications in many areas such as catalysis, ion separation and adsorption. Owing to the highly tunable compositi on and uniform distribution of metal cations in the brucite-like layers, as well as the facile exchangeability of intercalated anions, LDHs can be modified and functionalized to form various nanostructures/composites through versatile processes such as anion intercalation and exfoliation, decoration of nanoparticles, selfassembly with other two-dimensional (2D) materials, and controlled growth on conductive supports (e.g., nanowire arrays, nano tubes, 3D foams). In this article, we briefly review the recent advances on both the LDH nano structures and functionalized composites toward the applications in energy conversion, especially for water oxidation. | Xiaolong Deng Jinzhao Huang Hao Wan Fashen Chen Yifan Lin Xijin Xu Renzhi Ma Takayoshi Sasaki | 2019 | Journal of Energy Chemistry2019，28，5： | 2 |
| 7 | Photo-enhanced rechargeable high-energy-density metal batteries for solar energy conversion and storage显示文摘Solar energy is considered the most promising renewable energy source.Solar cells can harvest and convert solar energy into electrical energy,which needs to be stored as chemical energy,thereby realizing a balanced supply and demand for energy.As energy storage devices for this purpose,newly developed photo-enhanced rechargeable metal batteries,through the internal integration of photovoltaic technology and high-energy-density metal batteries in a single device,can simplify device configuration,lower costs,and reduce external energy loss.This review focuses on recent progress regarding the working principles,device architectures,and performances of various closed-type and open-type photo-enhanced rechargeable devices based on metal batteries,including Li/Zn-ion,Li-S,and Li/Zn-I_(2),and Li/Zn-O_(2)/air,Li-CO_(2),and Na-O_(2) batteries.In addition to provide a fundamental understanding of photo-enhanced rechargeable devices,key challenges and possible strategies are also discussed.Finally,some perspectives are provided for further enhancing the overall performance of the proposed devices. | Hairong Xue Hao Gong Yusuke Yamauchi Takayoshi Sasaki Renzhi Ma | 2022 | Nano Research Energy2022，1，1： | 2 |
| 8 | Microcrystallization and lattice contraction of NiFe LDHs for enhancing water electrocatalytic oxidation显示文摘The lattice-oxygen-mediated mechanism is considered as a reasonable mechanism for the electrochemical catalytic oxygen evolution reaction(OER)of NiFe layered double hydroxides(LDHs).A NiFe LDH with distinct lattice contraction and microcrystallization was synthesized via a simple one-step method using sodium gluconate.The lattice contraction is attributed to the interaction of carbon in sodium gluconate and iron in NiFe LDH.The NiFe LDH with optimized microcrystallization and lattice contraction shows a low overpotential of 217 mV at a current density of 10 mA cm^(−2) and excellent durability of 20 h at a high current density of 100 mA cm^(−2).The results revealed that a contractive metal–oxygen bond could boost the intrinsic activity of active sites and the microcrystallization promotes an increase in the number of active sites in terms of unit area.The chemical environment of oxygen elemental characterization and resistance at different chronopotentiometry times confirm that the lattice oxygen element is indeed involved in the process of OER,supporting the lattice-oxygen-mediated mechanism of NiFe LDH.Density functional theory calculations reveal that contractive metal–oxygen bonds induced a reduction of the adsorption energy barrier of intermediate products,thus improving the intrinsic catalytic activity.The special characteristics of microcrystallization and lattice contraction of NiFe LDH provide a strategy to improve both the number and the intrinsic activity of active sites in a versatile manner. | Zhicheng Zheng Dan Wu Gen Chen Ning Zhang Hao Wan Xiaohe Liu Renzhi Ma | 2022 | Carbon Energy2022，4，5： | 2 |

| 14 | Anchoring Active Sites by Pt_(2)FeNi Alloy Nanoparticles on NiFe Layered Double Hydroxides for Efficient Electrocatalytic Oxygen Evolution Reaction显示文摘Strategy of anchoring alloy nanoparticles made up of the efficient catalytic element(e.g.,Ni,Fe)on dodecyl sulfate(DS^(-))-intercalated NiFe layered double hydroxides(DS^(-)-NiFe LDH)obtained by a convenient one-step hydrothermal coprecipitation method for essentially enhancing oxygen evolution reaction(OER)performance was proposed.The results of structural characterization indicate Pt_(2)FeNi alloy nanoparticles evenly distribute on the surface of DS^(-)-NiFe LDH.The sizes of the Pt_(2)FeNi nanoparticles,closely related to their OER performance,could be wellcontrolled by adjusting the amount of H;PtCl;addition.The composite structure of as-prepared product was stable during processes of synthesis,exfoliation,self-assembly,and subsequent electrocatalytic OER.Rigorous electrochemical test proving the contributing catalytic active sites was located at the interface between Pt_(2)FeNi and DS^(-)-NiFe LDH,and the Ni and Fe were the major active elements while O atoms are adsorption sites.The formation of Pt_(2)FeNi nanoparticles could greatly prompt the reduction of Tafel slope.The best-performing Pt_(2)FeNi/DS^(-)-NiFe LDH with a Pt content of 0.98 wt%achieved low overpotential of 204 mV at 10 mA cm^(-2)and 262 mV at 50 mA cm^(-2).This work provides a convenient and effective strategy to create additional active sites for enhancing OER performance of NiFe LDH and make contribution to its wide application. | Zhicheng Zheng Yanru Guo Hao Wan Gen Chen Ning Zhang Wei Ma Xiaohe Liu Shuquan Liang Renzhi Ma | 2022 | Energy & Environmental Materials2022，5，1： | 1 |
