| 1 | Dynamical decoupling of electron spins in phosphorus-doped silicon显示文摘Quantum coherence is an important enabling feature underpinning quantum computation. However, because of couplings with its noisy surrounding environment, qubits suffer from the decoherence effects. The dynamical decoupling (DD) technique uses pulse-induced qubit flips to effectively mitigate couplings between qubits and environment. Optimal DD eliminates dephasing up to a given order with the minimum number of pulses. In this paper, we first introduce our recent work on prolonging electron spin coherence in γ-irradiated malonic acid crystals and analyze different decoherence mechanisms in this solid system. Then we focus on electron spin relaxation properties in another system, phosphorous-doped silicon (Si:P) crystals. These properties have been investigated by pulse electron paramagnetic resonance (EPR). We also investigate the performance of the dynamical decoupling technique on this system. Using 8-pulse periodic DD, the coherence time can be extended to 296 μs compared with 112 μs with one-pulse control. | RONG Xing WANG Ya YANG JiaHui ZHU JinXian XU WanJie FENG PengBo WEN XuJie SU JiHu DU JiangFeng | 2011 | Chinese Science Bulletin2011，56，7： | 4 |
| 2 | Functions for patch test in finite element analysis of the Mindlin plate and the thin cylindrical shell显示文摘Current patch test for Mindlin plate element only satisfies the zero shear deformation condition.The patch test of non-zero constant shear for Mindlin plate problem cannot be performed.For shell element, the patch test does not even exist.Based on the theory of enhanced patch test proposed by Chen W J (2006),the authors proposed the enhanced patch test function for Mindlin plate and thin cylindrical shell elements.This enhanced patch test function can be used to assess the convergence of the Mindlin plate and cylindrical thin shell elements. | CHEN WanJi 1,2 ,WANG JinZhi 1,3 &ZHAO Jie 1 1State Key Laboratory for Structural Analysis of Industrial Equipment,Dalian University of Technology,Dalian 116023,China 2Institute for Structural Analysis of Aerocraft,Shenyang Institute of Aeronautical Engineering,Shenyang 110136,China 3 College of Science,Institute of Dalian Nationalities,Dalian 116022,China | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，5： | 2 |
| 3 | Study on the viscoelastic behavior of SEEPS block copolymer based on a modified BSW model显示文摘Studies on the viscoelastic behavior of styrene- [ethylene-(ethylene-propylene)]-styrene block copolymer (SEEPS) were carried out, and some characteristic viscoelas-tic parameters were calculated. The longest relaxation time τmax was obtained through simulating the relaxation spec-trum on the basis of a modified Baumgaertel-Schausberger- Winter (mBSW) model. The results revealed that there exists a “second plateau” in the low frequency region of the master curves. The reason for this phenomenon is attributed to the entanglement of macromolecular chains. It is suggested that the hard blocks, polystyrene, act as entanglement points, resulting in a topology restraint to the movement of macro-molecular chains. Meanwhile, it is found that the horizontal shift factors (aT) vs temperature in the master curve could be fitted to the Williams-Landel-Ferry (WLF) equation and Ar-rhenius equation respectively and the flow activation energy (Ea) is 127.88 kJ/mol. In addition, the plateau modulus (GN0) and entanglement molecule weight (Me) were calculated. | WANG Wanjie ZHENG Qiang YU Qiuming | 2005 | Chinese Science Bulletin2005，50，19： | 2 |

| 6 | Visible transparent,infrared stealthy polymeric films with nanocoating of ITO@MXene enable efficient passive radiative heating and solar/electric thermal conversion显示文摘Visible transparent yet low infrared-emissivity(ε)polymeric materials are highly anticipated in many applications,whereas the fabrication of which remains a formidable challenge.Herein,visible transparent,flexible,and low-εpolymeric films were fabricated by nanocoating decoration of indium tin oxide(ITO)and MXene on polyethylene terephthalate(PET)film surface through magnetron sputtering and spray coating,respectively.The obtained PET-ITO@MXene(PET-IM)film exhibits lowεof 24.7%and high visible transmittance exceeding 50%,endowing it with excellent visible transparent infrared stealthy by reducing human skin radiation temperature from 32 to 20.8°C,and remarkable zero-energy passive radiative heating capability(5.7°C).Meanwhile,the transparent low-εPET-IM film has high solar absorptivity and electrical conductivity,enabling superior solar/electric to thermal conversion performance.Notably,the three heating modes of passive radiative and active solar/electric can be integrated together to cope with complex heating scenarios.These visible transparent low-εpolymeric films are highly promising in infrared stealth,building daylighting and thermal management,and personal precision heating. | Xingyuan Du Xiangxin Li Yuxuan Zhang Xinyi Guo Zhengji Li Yanxia Cao Yanyu Yang Wanjie Wang Jianfeng Wang | 2023 | Nano Research2023，16，2： | 1 |

| 14 | Manipulating the antioxidative capacity of melanin-like nanoparticles by involving condensation polymerization显示文摘Melanin is ubiquitous in nature and plays important roles in physiological activities especially in keeping the oxidative balance.Both natural and synthetic melanin were synthesized via the free radical polymerization of 5,6-dihydroxyindole(DHI)monomer,which may lead to the inherent compactπ-conjugation stacking microstructures and finally results in limited antioxidative capacities.To address this issue,we have strived to involve condensation polymerization during the melanin synthetic process,aiming to disrupt the compact stacking microstructures and improve the total antioxidative performance.The resulting melaninlike nanoparticles(NPs)indeed possessed less compact stackingπ-conjugation structures and decreased density,which further demonstrated enhanced antioxidative abilities compared with conventional melanin-like polymers such as poly-5,6-dihydroxyindole(Poly-DHI)and polydopamine(PDA).Their excellent free radical scavenging capability was further confirmed by the intracellular cell protection effects against reactive oxygen species(ROS)as well as in vivo therapy for acute diseases including acute kidney injury and acute liver injury.This work would promote future work toward new types of melanin-inspired nanomaterials with tunable and improved functions beyond nature. | Peng Yang Tianyou Wang Jianhua Zhang Hengjie Zhang Wanjie Bai Gaigai Duan Wei Zhang Jinrong Wu Zhipeng Gu Yiwen Li | 2023 | Science China Chemistry2023，66，5： | 1 |

| 17 | A Bioinspired Strategy Toward UV Absorption Enhancement of Melaninlike Polymers for Sun Protection显示文摘Due to the complexity of the structure within melanin and synthetic polymers(i.e.,polydopamine,PDA),it is a challenge to regulate the ultraviolet(UV)absorption.In nature,melanocytes can biosynthesize more pheomelanins than eumelanins via protein and gene overexpression for photoprotection when the UV irradiation is enhanced.During this biosynthetic pathway,L-cystine,transported by xCT gene,can be involved to form a new monomer structure incorporating a benzothiazole group,finally resulting in the formation of UV absorption-enhanced pheomelanin.Inspired by this,we have proposed a facile strategy to regulate the UV absorption of PDA by introducing the benzimidazole(BI)unit through the thiol-Michael addition reaction during the polymerization process.It was further found that the introduction of BI units not only significantly increased the content of chromophores and auxochromes,but also effectively restricted the red-shift of the absorption spectrum via interrupting the conjugated microstructure within PDA,both of which contribute to UV absorption enhancement.These UV absorption-enhanced PDA nanoparticles could be used to fabricate bio-inspired sunscreens for efficient sun protection.This work will provide a facile strategy to regulate UV absorption of melanin-like materials and open new horizons for the design and construction of bioinspired sunscreens. | Zhen Yang Jianhua Zhang Huijie Liu Junfei Hu Xianheng Wang Wanjie Bai Wei Zhang Ye Yang Zhipeng Gu Yiwen Li | 2023 | CCS Chemistry2023，5，10： | 1 |
| 18 | Role of Ppt1 in multiple stress responses in Candida albicans显示文摘To study the function of CaPpt1,we deleted PPT1 gene from the Candida albicans genome by sequentially replacing the entire coding region with the selectable markers ARG4 and HIS1.The results showed that the deletion of Ppt1 did not affect the hyphal formation of C.albicans under serum induction and caused enhanced sensitivity to DNA damage,Calcofluor white and saltinduced stress.We also found that Ppt1 was not required for the phenotypic response of cells treated with the genotoxins,methylmethane sulfonate and hydroxyurea.Flow cytometric analyses indicated that ppt1D cells and wild-type cells showed similar G2/M arrest profiles when exposed to DNA damage stress.Ppt1 was not required for the activation of the DNA damage response pathway,as indicated by normal phosphorylation of Rad53 and Rfa2 in ppt1D cells under DNA damage stress.We suggest that Ppt1 plays important roles in response to various stress conditions in C.albicans. | Kangdi Hu Wanjie Li Jiaxin Gao Qizheng Liu Haitao Wang Yue Wang Jianli Sang | 2014 | Chinese Science Bulletin2014，59，31： | 1 |
| 19 | Low infrared emitter from Ti3C2Tx MXene towards highly-efficient electric/solar and passive radiative heating显示文摘Realizing all-day and all-weather energy-saving heating is crucial for mitigating the global energy and ecology crisis.Electric/solar heating are two promising heating approaches,yet materials with high elec-trical conductivity,high solar absorptivity,and low infrared emissivity at the same time are rare in na-ture,which are highly anticipated and of great significance for highly efficient electric/solar heating.In this work,we demonstrate that Ti_(3)C_(2)T_(x) MXene with low IR emissivity(14.5%)fills the gap in the absence of the above materials,exhibiting a remarkable electric/solar heating performance.The saturated heating temperature of Ti_(3)C_(2)T_(x) film reaches a record-high value of 201°C at a low driving voltage of 1.5 V,and reaches 84.3°C under practical solar irradiation(750 W/m^(2))with a high solar to the thermal conversion efficiency of 75.3%,which is far superior to other reported materials.Meanwhile,the low IR emissivity endows Ti_(3)C_(2)T_(x) with a remarkable passive radiative heating capability of 7.0°C,ensuring zero-energy heating without electric/solar energy supply.The intrinsic characteristic of high electrical conductivity,high solar absorptivity,and low IR emissivity makes Ti_(3)C_(2)T_(x) unique existence in nature,which is highly promising for all-day and all-weather energy-saving heating. | Mingming Shen Jiahao Ni Yanxia Cao Yanyu Yang Wanjie Wang Jianfeng Wang | 2023 | Journal of Materials Science & Technology2023，，2： | 1 |
| 20 | Influence of nano-mechanical evolution of Ti_(3)AlC_(2) ceramic on the arc erosion resistance of Ag-based composite electrical contact material显示文摘Al-containing MAX phase ceramic has demonstrated great potential in the field of high-performance low-voltage electrical contact material.Elucidating the anti-arc erosion mechanism of the MAX phase is crucial for further improving performance,but it is not well-understood.In this study,Ag/Ti_(3)AlC_(2) electrical contact material was synthesized by powder metallurgy and examined by nanoindentation techniques such as constant loading rate indentation,creep testing,and continuous stiffness measurements.Our results indicated a gradual degradation in the nano-mechanical properties of the Ti_(3)AlC_(2) reinforcing phase with increasing arc erosion times,although the rate of this degradation appeared to decelerate over arc erosion times.Specifically,continuous stiffness measurements highlighted the uneven mechanical properties within Ti_(3)AlC_(2),attributing this heterogeneity to the phase’s decomposition.During the early(1-100 times)and intermediate(100-1000 times)stages of arc erosion,the decline in the nano-mechanical properties of Ti_(3)AlC_(2) was primarily ascribed to the decomposition of Ti_(3)AlC_(2) and limited surface oxidation.During the later stage of arc erosion(1000-6200 times),the inner region of Ti_(3)AlC_(2) also sustained arc damage,but a thick oxide layer formed on its surface,enhancing the mechanical properties and overall arc erosion resistance of the Ag/Ti_(3)AlC_(2). | Xuelian Wu Chengzhe Wu Xinpeng Wei Wanjie Sun Chengjian Ma Yundeng Zhang Gege Li Liming Chen Dandan Wang Peigen Zhang Zhengming Sun Jianxiang Ding | 2024 | Journal of Advanced Ceramics2024，13，2： | 0 |
