| 2 | Macroscopic Electromagnetic Cooperative Network‑Enhanced MXene/Ni Chains Aerogel‑Based Microwave Absorber with Ultra‑Low Matching Thickness显示文摘Electromagnetic cooperative strategy has been presented as a mainstream approach that can effectively optimize the matching thickness of dielectric loss dominant system.However,it is still challenging for dielectric–magnetic loss coexisting-type absorber to develop electromagnetic wave(EMW)performance with ultra-low matching thickness(≤1 mm).Breaking the limitation of traditional electromagnetic response at microscopic/mesoscopic scale,a ficus microcarpa-like magnetic aerogel with macroscopical electromagnetic cooperative effect was fabricated through highly oriented self-assembly engineering.The highly oriented Ni chains with unique macroscopic morphology(~1 cm in length)were achieved via a special magnetic field-induced growth.Strong magnetic coupling was observed in the Ni chains confirmed by the micromagnetic simulation.The deductive calculation validates that maintaining high value of electromagnetic parameters at high frequencies is the prerequisites of ultrathin absorber.The electromagnetic cooperative networks with uninterrupted and dual pathways spread through the entire aerogel skeleton,resulting in the impressive permittivity even at high frequencies.Consequently,the aerogel exhibits a remarkable EMW performance at an ultrathin thickness of 1 mm.Thus,based on the modulation of electromagnetic parameters,this work proposed a macroscopic ordered structure with the electromagnetic cooperative effect useful to develop a suitable strategy for achieving ultrathin EMW absorbers. | Fei Pan Yanping Rao Dan Batalu Lei Cai Yanyan Dong Xiaojie Zhu Yuyang Shi Zhong Shi Yaowen Liu Wei Lu | 2022 | Nano-Micro Letters2022，14，8： | 1 |
| 3 | Heterointerface Engineering of β‑Chitin/Carbon Nano‑Onions/Ni-P Composites with Boosted Maxwell‑Wagner‑Sillars Effect for Highly Efficient Electromagnetic Wave Response and Thermal Management显示文摘The rational construction of microstructure and composition with enhanced Maxwell-Wagner-Sillars effect(MWSE)is still a challenging direction for reinforcing electromagnetic wave(EMW)absorption performance,and the related EMW attenuation mechanism has rarely been elucidated.Herein,MWSE boostedβ-chitin/carbon nano-onions/Ni–P composites is prepared according to the heterointerface engineering strategy via facile layer-by-layer electrostatic assembly and electroless plating techniques.The heterogeneous interface is reinforced from the aspect of porous skeleton,nanomaterials and multilayer construction.The composites exhibit competitive EMW response mechanism between the conductive loss and the polarization/magnetic loss,as describing like the story of“The Hare and the Tortoise”.As a result,the composites not only achieve a minimum reflection loss(RL_(min))of−50.83 dB and an effective bandwidth of 6.8 GHz,but also present remarkable EMW interference shielding effectiveness of 66.66 dB.In addition,diverse functions such as good thermal insulation,infrared shielding and photothermal performance were also achieved in the hybrid composites as a result of intrinsic morphology and chemicophysics properties.Therefore,we believe that the boosted MWSE open up a novel orientation toward developing multifunctional composites with high-efficient EMW response and thermal management. | Fei Pan Lei Cai Yuyang Shi Yanyan Dong Xiaojie Zhu Jie Cheng Haojie Jiang Xiao Wang Yifeng Jiang Wei Lu | 2022 | Nano-Micro Letters2022，14，5： | 1 |

| 5 | Optimization on microstructure,mechanical properties and damping capacities of duplex structured Mg–8Li–4Zn–1Mn alloys显示文摘Optimizing the mechanical properties and damping capacity of the duplex-structured Mg–Li–Zn–Mn alloy by tailoring the microstructure via hot extrusion was investigated.The results show that the Mg–8Li–4Zn–1Mn alloy is mainly composed ofα-Mg,β-Li,Mg–Li–Zn and Mn phases.The microstructure of the test alloy is refined owing to dynamic recrystallization(DRX)during hot extrusion.After hot extrusion,the crushed precipitates are uniformly distributed in the test alloy.The yield strength(YS),ultimate tensile strength(UTS),and elongation(EL)of as-extruded alloy reach 156 MPa,208 MPa,and 32.3%,respectively,which are much better than that of as-cast alloy.Furthermore,the as-extruded and as-cast alloys both exhibit superior damping capacities,with the damping capacity(Q^(-1))of 0.030 and 0.033 at the strain amplitude of 2×10^(-3),respectively.The mechanical properties of the test alloy can be significantly improved by hot extrusion,whereas the damping capacities have no noticeable change,which indicates that the duplex-structured Mg–Li alloys with appropriate mechanical properties and damping properties can be obtained by alloying and hot extrusion. | Tongtong Cao Yong Zhu Yuyang Gao Yan Yang Gang Zhou Xiaofei Cui Chen Wen Bin Jiang Xiaodong Peng Fusheng Pan | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，5： | 1 |
| 6 | A Holistic Energy-Efficient Approach for a Processor-Memory System显示文摘Component overclocking is an effective approach to speed up the components of a system to realize a higher program performance; it includes processor overclocking or memory overclocking. However, overclocking will unavoidably result in increase in power consumption. Our goal is to optimally improve the performance of scientific computing applications without increasing the total power consumption for a processor-memory system. We built a processor-memory energy efficiency model for multicore-based systems, which coordinates the performance and power of processor and memory. Our model exploits performance boost opportunities for a processor-memory system by adopting processor overclocking, processor Dynamic Voltage and Frequency Scaling(DVFS), memory active ratio adjustment, and memory overclocking, according to different scientific applications.This model also provides a total power control method by considering the same four factors mentioned above. We propose a processor and memory Coordination-based holistic Energy-Efficient(CEE) algorithm, which achieves performance improvement without increasing the total power consumption. The experimental results show that an average of 9.3% performance improvement was obtained for all 14 benchmarks. Meanwhile the total power consumption does not increase. The maximal performance improvement was up to 13.1% from dedup benchmark.Our experiments validate the effectiveness of our holistic energy-efficient model and technology. | Feihao Wu Juan Chen Yong Dong Wenxu Zheng Xiaodong Pan Yuan Yuan Zhixin Ou Yuyang Sun | 2019 | Tsinghua Science and Technology2019，24，4： | 1 |
| 7 | Optical properties of Zn-diffused InP layers for the planar-type InGaAs/InP photodetectors显示文摘Zn diffusion into InP was carried out ex-situ using a new Zn diffusion technique with zinc phosphorus particles placed around InP materials as zinc source in a semi-closed chamber formed by a modified diffusion furnace.The optical characteristics of the Zn-diffused InP layer for the planar-type InGaAs/InP PIN photodetectors grown by molecular beam epitaxy(MBE) has been investigated by photoluminescence(PL) measurements. The temperature-dependent PL spectrum of Zn-diffused InP samples at different diffusion temperatures showed that band-to-acceptor transition dominates the PL emission, which indicates that Zn was commendably diffused into InP layer as the acceptor. High quality Zn-diffused InP layer with typically smooth surface was obtained at 580 °C for 10 min. Furthermore, more interstitial Zn atoms were activated to act as acceptors after a rapid annealing process.Based on the above Zn-diffusion technique, a 50 μm planar-type InGaAs/InP PIN photodector device was fabricated and exhibited a low dark current of 7.73 pA under a reverse bias potential of.5 V and a high breakdown voltage of larger than 41 V(I < 10 μA). In addition, a high responsivity of 0.81 A/W at 1.31 μm and 0.97 A/W at 1.55 μm was obtained in the developed PIN photodetector. | Guifeng Chen Mengxue Wang Wenxian Yang Ming Tan Yuanyuan Wu Pan Dai Yuyang Huang Shulong Lu | 2017 | Journal of Semiconductors2017，38，12： | 0 |

| 9 | Wearable and interactive multicolored photochromic fiber display显示文摘Endowing flexible and adaptable fiber devices with light-emitting capabilities has the potential to revolutionize the current design philosophy of intelligent,wearable interactive devices.However,significant challenges remain in developing fiber devices when it comes to achieving uniform and customizable light effects while utilizing lightweight hardware.Here,we introduce a mass-produced,wearable,and interactive photochromic fiber that provides uniform multicolored light control.We designed independent waveguides inside the fiber to maintain total internal reflection of light as it traverses the fiber.The impact of excessive light leakage on the overall illuminance can be reduced by utilizing the saturable absorption effect of fluorescent materials to ensure light emission uniformity along the transmission direction.In addition,we coupled various fluorescent composite materials inside the fiber to achieve artificially controllable spectral radiation of multiple color systems in a single fiber.We prepared fibers on mass-produced kilometer-long using the thermal drawing method.The fibers can be directly integrated into daily wearable devices or clothing in various patterns and combined with other signal input components to control and display patterns as needed.This work provides a new perspective and inspiration to the existing field of fiber display interaction,paving the way for future human–machine integration. | Pan Li Yuwei Wang Xiaoxian He Yuyang Cui Jingyu Ouyang Ju Ouyang Zicheng He Jiayu Hu Xiaojuan Liu Hang Wei Yu Wang Xiaoling Lu Qian Ji Xinyuan Cai Li Liu Chong Hou Ning Zhou Shaowu Pan Xiangru Wang Huamin Zhou Cheng-Wei Qiu Yan-Qing Lu Guangming Tao | 2024 | Light(Science & Applications)2024，13，3： | 0 |
| 10 | Outcomes of patients who have undergone laparoscopic abdominal cerclage:A retrospective study显示文摘Objective:This study aims to evaluate the surgical morbidity and obstetric outcomes following in-pregnancy or pre-pregnancy laparoscopic abdominal cerclage(LAC)for patients who were diagnosed with refractory cervical insufficiency or had a short cervix.Methods:A retrospective study was conducted on patients undergoing LAC between May 2017 and May 2019 at the Department of Obstetrics and Gynecology,Sir Run Run Shaw Hospital.The patients were diagnosed with refractory cervical insufficiency based upon a previous failed transvaginal cervical cerclage(TVC),or had a short cervix who were considered unsuitable for a TVC after a previous cervical procedure.All patients were followed-up after surgery with transperineal ultrasonography until May 2020.Subsequently,surgical and obstetric data were collected and analyzed.Results:In total,44 patients underwent LAC,with 8 patients in-pregnancy and 36 pre-pregnancy.For the patient with pre-pregancy LAC,the pregnancy rate was 80.6%(29/36),including 3 patients with first-trimester loss,1 patient with an ectopic pregnancy,and 25 patients with a delivery.For the remaining 7 patients,3 did not conceive,and another 4 had no pregnancy plans.All the patients with in-pregnancy LAC had a delivery.The“take-home baby”rate was 89.2%(33/37),with a live-birth rate of 100%and a neonatal survival rate of 100%for both patients with in-pregnancy and pre-pregnancy LAC.For patients with in-pregnancy LAC,75.0%(6/8)patients delivered at≥37 wk of gestation,12.5%(1/8)delivered between 34 and 36^(+6)wk,and 12.5%(1/8)delivered between 28 and 33^(+6)wk.For patients with pre-pregnancy LAC,80.0%(20/25)patients delivered at≥37 wk of gestation,16.0%(4/25)delivered between 34 and 36^(+6)wk,and 4.0%(1/25)delivered between 28 and 33^(+6)wk.No adverse-event intra-operative or post-operative sequelae were noted.Conclusions:LAC is an effective and safe procedure that results in remarkable obstetric outcomes for women with refractory cervical insufficiency,or with a short cervix who are considered unsuitable for a TVC.The success rate of in-pregnancy or pre-pregnancy LAC depends on a full evaluation of patients,a proper peri-operative management and close follow-up. | Cuiyu Yang Dong Huang Yang Yang Jingyan Yang Yuyang Chen Mei Pan Songying Zhang | 2022 | Laparoscopic, Endoscopic and Robotic Surgery2022，5，3： | 0 |

| 12 | An interlocked coordination cage based on aromatic amide ligands显示文摘An interlocked M_(4) L_(8) coordination cage was synthesized by coordination-driven self-assembly of palladium(Ⅱ)ions with aromatic amide bidentate ligands.The reaction of the ligand and the metal at 2:1 ratio led to the monomeric M_(2) L_(4) cage as the kinetic product,while the thermodynamic product M_(4) L_(8) cage was obtained by prolongating the reaction.This conve rsion and the interlocked structure was clearly revealed by using~1 H NMR,mass spectrometry and X-ray crystallography.The driving force of interlocking was mainly attributed to the interactions(hydrogen bonding,aromatic stacking and electrostatic interaction)arising from the aptitude of flexibility of the amide ligand. | Dan Luo Bo Pan Jiajia Zhang Chunmiao Ma Yuyang Su Quan Gan | 2021 | Chinese Chemical Letters2021，32，4： | 0 |
| 13 | Efficient photoelectrochemical conversion of CO_(2)to syngas by photocathode engineering显示文摘The synthesis of renewable chemical fuels from CO_(2) and H_(2)O via photoelectrochemical(PEC)route reprensents a promising room-temperature approach for transforming greenhouse gas into value-added chemicals(e.g.,syngas),but to date it has been hampered by the lack of efficient photocathode for CO_(2) reduction.Herein,we report efficient PEC CO_(2) reduction into syngas by photocathode engineering.The photocathode is consisting of a planar p-n Si junction for strong light harvesting,GaN nanowires for efficient electron extraction and transfer,and Au/TiO_(2)for rapid electrocatalytic syngas production.The photocathode yields a record-high solar energy conversion efficiency of 2.3%.Furthermore,desirable syngas compositions with CO/H_(2)ratios such as 1:2 and 1:1 can be produced by simply varying the size of Au nanoparticle.Theoretical calculations reveal that the active sites for CO and H_(2)generation are the facet and undercoordinated sites of Au particles,respectively. | Sheng Chu Pengfei Ou Roksana Tonny Rashid Yuyang Pan Daolun Liang Huiyan Zhang Jun Song | 2022 | Green Energy & Environment2022，7，3： | 0 |
| 14 | Sulforaphane prevents LPS‑induced inflammation by regulating the Nrf2‑mediated autophagy pathway in goat mammary epithelial cells and a mouse model of mastitis显示文摘Background Mastitis not only deteriorates the composition or quality of milk,but also damages the health and pro-ductivity of dairy goats.Sulforaphane(SFN)is a phytochemical isothiocyanate compound with various pharmacologi-cal effects such as anti-oxidant and anti-inflammatory.However,the effect of SFN on mastitis has yet to be elucidated.This study aimed to explore the anti-oxidant and anti-inflammatory effects and potential molecular mechanisms of SFN in lipopolysaccharide(LPS)-induced primary goat mammary epithelial cells(GMECs)and a mouse model of mastitis.Results In vitro,SFN downregulated the mRNA expression of inflammatory factors(tumor necrosis factor-α(TNF-α),interleukin(IL)-1βand IL-6),inhibited the protein expression of inflammatory mediators(cyclooxygenase-2(COX2),and inducible nitric oxide synthase(iNOS))while suppressing nuclear factor kappa-B(NF-κB)activation in LPS-induced GMECs.Additionally,SFN exhibited an antioxidant effect by increasing Nrf2 expression and nuclear translocation,up-regulating antioxidant enzymes expression,and decreasing LPS-induced reactive oxygen species(ROS)produc-tion in GMECs.Furthermore,SFN pretreatment promoted the autophagy pathway,which was dependent on the increased Nrf2 level,and contributed significantly to the improved LPS-induced oxidative stress and inflammatory response.In vivo,SFN effectively alleviated histopathological lesions,suppressed the expression of inflammatory factors,enhanced immunohistochemistry staining of Nrf2,and amplified of LC3 puncta LPS-induced mastitis in mice.Mechanically,the in vitro and in vivo study showed that the anti-inflammatory and anti-oxidative stress effects of SFN were mediated by the Nrf2-mediated autophagy pathway in GMECs and a mouse model of mastitis.Conclusions These results indicate that the natural compound SFN has a preventive effect on LPS-induced inflam-mation through by regulating the Nrf2-mediated autophagy pathway in primary goat mammary epithelial cells and a mouse model of mastitis,which may improve prevention strategies for mastitis in dairy goats. | Dan Shao Wenxiang Shen Yuyang Miao Zhen Gao Menghao Pan Qiang Wei Zuoting Yan Xiaoe Zhao Baohua Ma | 2023 | Journal of Animal Science and Biotechnology2023，14，5： | 0 |
