| 5 | Boosting overall water splitting by incorporating sulfur into NiFe(oxy)hydroxide显示文摘Developing highly active and cost-effective electrocatalysts for enhancing the hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)is a significant challenge for overall water splitting.Sulfur-incorporated nickel iron(oxy)hydroxide(S-NiFeOOH)nanosheets were directly grown on commercial nickel foam using a galvanic corrosion method and a hydrothermal method.The incorporation of sulfur into NiFeOOH enhanced the catalytic activity for the HER and OER in 1 M KOH electrolyte.The enhanced catalytic activity is attributed to the change in the local structure and chemical states due to the incorporation of sulfur.High performance for overall water splitting was achieved with an alkaline water electrolyzer.This was realized by employing S-NiFeOOH as a bifunctional electrocatalyst,thereby outperforming a water electrolyzer that requires the usage of precious metal electrocatalysts(i.e.,Pt/C as the HER electrocatalyst and IrO_(2) as the OER electrocatalyst).Moreover,when driven by a commercial silicon solar cell,an alkaline water electrolyzer that uses S-NiFeOOH as a bifunctional electrocatalyst generated hydrogen under natural illumination.This study shows that S-NiFeOOH is a promising candidate for a large-scale industrial implementation of hydrogen production for overall water splitting because of its low cost,high activity,and durability.In addition,the solar-driven water electrolyzer using S-NiFeOOH as a bifunctional electrocatalyst affords the opportunity for developing effective and feasible solar power systems in the future. | Chiho Kim Seong Hyun Kim Seunghun Lee Ilyeong Kwon Seong Hyun Kim Shinho kim Changgyu Seok Yoo Sei Park Yangdo Kim | 2022 | Journal of Energy Chemistry2022，31，1： | 1 |

| 9 | Self-organization of various“phase-separated”nanostructures in a single chemical vapor deposition显示文摘Chemical vapor deposition(CVD)is one of the most versatile techniques for the controlled synthesis of functional nanomaterials.When multiple precursors are induced,the CVD process often gives rise to the growth of doped or alloy compounds.In this work,we demonstrate the self-assembly of a variety of‘phase-separated’functional nanostructures from a single CVD in the presence of various precursors.In specific,with silicon substrate and powder of Mn and SnTe as precursors,we achieved self-organized nanostructures including Si/SiOx core-shell nanowire heterostructures both with and without embedded manganese silicide particles,Mn11Si19 nanowires,and SnTe nanoplates.The Si/SiOx core-shell nanowires embedded with manganese silicide particles were grown along the<111>direction of the crystalline Si via an Au-catalyzed vapor-liquid-solid process,in which the Si and Mn vapors were supplied from the heated silicon substrates and Mn powder,respectively.In contrast,direct vapor-solid deposition led to particle-free<110>-oriented Si/SiOx core-shell nanowires and<100>-oriented Mn11Si19 nanowires,a promising thermoelectric material.No Sn or Te impurities were detected in these nanostructures down to the experimental limit.Topological crystalline insulator SnTe nanoplates with dominant{100}and{111}facets were found to be free of Mn(and Si)impurities,although nanoparticles and nanowires containing Mn were found in the vicinity of the nanoplates.While multiple-channel transport was observed in the SnTe nanoplates,it may not be related to the topological surface states due to surface oxidation.Finally,we carried out thermodynamic analysis and density functional theory calculations to understand the‘phase-separation’phenomenon and further discuss general approaches to grow phase-pure samples when the precursors contain residual impurities. | Jinmei Wang Dongyue Xie Zhen Li Xiaohang Zhang Xing Sun Amanda L.Coughlin Thomas Ruch Qiang Chen Yaroslav Losovyj Seunghun Lee Heshan Yu Haidong Zhou Haiyan Wang Jian Wang Shixiong Zhang | 2020 | Nano Research2020，13，6： | 0 |
| 10 | Conditioned secretome of adipose-derived stem cells improves dextran sulfate sodium-induced colitis in mice显示文摘BACKGROUND Inflammatory bowel diseases(IBD)is related to uncontrolled immune response.Currently,there is no successful treatment for significant improvement in IBD.Stem cells display their therapeutic effects through their repopulating capacity or secreting factors.AIM To investigate the effects of conditioned mouse adipose-derived stem cells(mADSCs)secretome on colitis-induced mice.METHODS mADSCs were isolated from adipose tissue of C57BL/6 mice.Conditioned mADSCs secrectome was obtained by culturing of mADSCs with lipopolysaccharides(LPS,1μg/mL)for 24 h.Acute colitis was induced by 2%dextran sulfate sodium(DSS)drinking water for 7 d and then normal drinking water for 4 d.The mice were treated with normal culture medium(NM group),conditioned mADSCs secretome(CM group)or mADSCs(SC group).The length of colon and histopatholgy of colon tissues were evaluated.The mRNA expression levels of inflammatory cytokines in colon tissue and the serum interleukin(IL)-6 levels were determined.RESULTS The isolated mADSCs maintained the mADSCs specific gene expression profiles during experiment.The conditioned mADSCs secretome released by the treatment of mADSCs with LPS contained mainly inflammatory chemokines,colony-stimulating factors and inflammatory cytokines.The loss of body weight and reduction in colon length were ameliorated in the CM group.The conditioned mADSCs secretome reduced the histological score in colon tissue.The expression of IL-1b and IL-6 mRNAs in colon tissues significantly inhibited in the CM group compared to SC group and NM group,respectively.The elevation of serum IL-6 levels was also ameliorated in the CM group.These results indicate that the conditioned mADSCs secretome suppressed the synthesis of inflammatory cytokines in damaged colon tissue and the elevation of serum IL-6 concentration in DSS-induced mice CONCLUSION Conditioned mADSCs secretome might play regenerative roles by the suppression of IL-6 in serum and tissue during acute colitis,and may be more effective than stem cells themselves in the regeneration of colon tissue. | Seunghun Lee Jeonghoon Heo Eun-Kyung Ahn Jae Hyun Kim Young-Ho Kim Hee-Kyung Chang Sang-Joon Lee Jongsik Kim Seun-Ja Park | 2021 | World Journal of Gastroenterology2021，27，23： | 0 |
| 11 | 韩国绿色种养循环农业发展概况与经验启示显示文摘联合国将碳中和视为当今世界最为紧迫的任务,而农业是温室气体排放最多的产业之一,各国相继出台政策积极开展农业农村减排工作。韩国自2012年开始逐渐减少海洋粪污排泄量,并大力实行绿色种养循环农业,解决本国内畜禽粪污问题。韩国作为中国的重要海上邻国,不论是从研究借鉴角度抑或生态系统共享角度,了解其环境保护政策都是十分必要的。本文从韩国实施的主要政策、各地区农地养分收支现状、代表性运营模式案例、政策关注焦点等方面介绍韩国绿色种养循环农业的发展概况,结合中国绿色种养循环农业现状开展研究。提出三点政策建议:第一,进一步完善畜禽粪污资源化利用机具补贴辅助管理系统,提高系统在农户中的普及率;第二,提高全民环保意识的同时,政府的角色不应局限自上而下的引导型,应该积极促进种植户和养殖户间的自发组织,并大力提倡吸纳社会资本,集结社会各方力量;第三,促进绿色种养循环农业产品的商品化和品牌化,从而调动农户参与绿色种养循环农业的积极性。 | 全银华 LEE Seunghun LIM Changsik KIM Changgil IM Jeongbin | 2023 | 中国环境管理2023，15，3： | 0 |
