| 1 | Investigation on the temperature-dependence of absorption properties of solar cells with micro-structured surfaces显示文摘The temperature of a solar cell will increase when it is exposed to the sunlight,which results in variations of optical parameters and thermal expansion coefficient of the cell,thus affecting its spectral absorption feature.This paper is aimed to investigate the effects of temperature on the absorption property of solar cells with micro-structured surfaces.By taking hemispherical, cylindrical and spherical surfaces as models,numerical computation is conducted to obtain spectral distribution of absorptance of such surfaces with different structural parameters by means of the finite difference time domain(FDTD)method.Furthermore,the effects of material properties and structural period on the absorption property are also investigated. | YANG LiLi,XUAN YiMin ,HAN YuGe&TAN JunJie School of Power Engineering,Nanjing University of Science&Technology,Nanjing 210094,China | 2010 | Science China(Technological Sciences)2010，53，8： | 4 |
| 2 | Deformation tests and failure process analysis of an anchorage structure显示文摘In order to study the failure process of an anchorage structure and the evolution law of the body’s deformation field,anchor push-out tests were carried out based on digital speckle correlation methods(DSCM).The stress distribution of the anchorage interface was investigated using the particle flow numerical simulation method.The results indicate that there are three stages in the deformation and failure process of an anchorage structure:elastic bonding stage,a de-bonding stage and a failure stage.The stress distribution in the interface controls the stability of the structure.In the elastic bonding stage,the shear stress peak point of the interface is close to the loading end,and the displacement field gradually develops into a‘‘V’’shape.In the de-bonding stage,there is a shear stress plateau in the center of the anchorage section,and shear strain localization begins to form in the deformation field.In the failure stage,the bonding of the interface fails rapidly and the shear stress peak point moves to the anchorage free end.The anchorage structure moves integrally along the macro-crack.The de-bonding stage is a research focus in the deformation and failure process of an anchorage structure,and plays an important guiding role in roadway support design and prediction of the stability of the surrounding rock. | Zhao Tongbin Yin Yanchun Tan Yunliang Song Yimin | 2015 | International Journal of Mining Science and Technology2015，25，2： | 4 |
| 3 | Scoring the collective effects of SNPs: association of minor alleles with complex traits in model organisms显示文摘It has long been assumed that most parts of a genome and most genetic variations or SNPs are non-functional with regard to reproductive fitness.However,the collective effects of SNPs have yet to be examined by experimental science.We here developed a novel approach to examine the relationship between traits and the total amount of SNPs in panels of genetic reference populations.We identified the minor alleles(MAs)in each panel and the MA content(MAC)that each inbred strain carried for a set of SNPs with genotypes determined in these panels.MAC was nearly linearly linked to quantitative variations in numerous traits in model organisms,including life span,tumor susceptibility,learning and memory,sensitivity to alcohol and anti-psychotic drugs,and two correlated traits poor reproductive fitness and strong immunity.These results suggest that the collective effects of SNPs are functional and do affect reproductive fitness. | YUAN DeJian ZHU ZuoBin TAN XiaoHua LIANG Jie ZENG Chen ZHANG JieGen CHEN Jun MA Long DOGAN Ayca BROCKMANN Gudrun GOLDMANN Oliver MEDINA Eva RICE Amanda D.

| 9 | Dynamic Characteristics Analysis with Multi-Directional Coupling in a TBM Mainframe显示文摘The cutterhead of a full-face rock tunnel boring machine(TBM)is constantly subjected to varying impact and dynamic loads during tunneling processes,resulting in relatively large vibrations that could easily lead to fatigue cracking of the entire machine and a ect the tunneling performance and efficiency.To explore the dynamic characteristics of the TBM mainframe,a TBM from a water-diversion project is investigated in this research.According to the TBM vibration transmission route,an equivalent dynamic model of the TBM mainframe is established using the lumped-mass method in which the relevant dynamic parameters are solved.Additionally,the dynamic response characteristics of the TBM mainframe are analyzed.The results indicate that the vibration levels in three directions are approximately the same,the multi-directional vibration of the cutterhead is more intense than that of other components,and the vibration and external excitation exhibit identical change trends.A set of vibration field tests is performed to analyze the in situ dynamic responses of the mainframe and verify the correctness of the dynamic model.The theoretical and measured acceleration values of the TBM mainframe have the same magnitude,which proves the validity of the dynamic model and its solution.The aforementioned results provide an important theoretical value and practical significance for the design and assessment of the TBM mainframe. | Laikuang Lin Yimin Xia Zhengguang Li Caizhang Wu Yongliang Cheng Qing Tan | 2019 | Chinese Journal of Mechanical Engineering2019，32，6： | 1 |

| 14 | Development and evaluation of a thermostatic nucleic acid testing device based on magnesium pyrophosphate precipitation for detecting Enterocytozoon hepatopenaei显示文摘Enterocytozoon hepatopenaei(EHP)infection has seriously affected prawn culture globally.The symptoms of the infection are not apparent,and traditional detection methods are time consuming and low in accuracy.We developed a new onsite rapid testing device(size 18.8×16.7×6.6 cm^(3))for EHP based on magnesium pyrophosphate precipitation and facilitated by loop mediated isothermal amplification(LAMP).The design and fabrication of the device enables efficient light absorbance.The device has a highly sensitive detector,high-precision thermal controller,and humanized touch screen.The temperature control precision of the device is 0.2-0.3℃ at 60℃,63℃,and 65℃.The coefficients of variation values(CVV)of the luminous power in one channel at light on and off were found to be 0.0097 and 0.0014,respectively,within 1 h.The CVV of the background,luminous power,and values of eight PCR tubes filled with pure water were all less than 5%.In the EHP experiment,eight samples(including seven positive and one negative)confirmed the effectiveness of the device,and four positive and four negative samples verified whether cross-contamination exists.Among them,the rise time of the curve was about 15 min.These results assert that the developed device exhibits enhanced stability and uniformity and has excellent performance with high sensitivity,good specificity,and low testing time.Moreover,the optimal and minimum absorbance range was 555-655 nm for monitoring the production of LAMP. | Zhu Chen Kaixuan Zhao Ziyu He Xiaofang Luo Zuodong Qin Yimin Tan Xiangming Zheng Zuozhong Wu Yan Deng Hui Chen Yuan Guo Song Li | 2022 | Chinese Chemical Letters2022，33，8： | 0 |
| 15 | Pharmacokinetics of fucoidan and low molecular weight fucoidan from Saccharina japonica after oral administration to mice显示文摘The brown seaweed,Sacchairna japonica,has been used in traditional Chinese medicine for over one thousand years.Oral administration of fucoidan or low molecular weight fucoidan(LMWF)from S.japonica could ameliorate kidney dysfunction in chronic kidney diseases and inhibit diabetic vascular complications.In many studies,LMWF was found to be more potent than fucoidan with high molecular weight.However,the pharmacokinetics of LMWF still remains unclear.The purpose of the research is to compare the pharmacokinetics of fucoidan with high molecular weight(136 kDa)with that low molecular weight(9.5 kDa)after oral administration to ICR mice.Since fucose is the main and representative monosaccharide of fucoidans,we evaluate the pharmacokinetics of fucoidan and LMWF by determining the fucose concentration in mice serum.Both fucoidan and LMWF were absorbed following oral administration.Fucoidan and LMWF were provided to mice by oral administration with 60 mg/kg and the maximum Concentration(C_(max))was found at 2.5 h(0.66±0.32 mg/L)for Fucoidan and 1.5 h(1.01±0.56 mg/L)for LMWF,respectively.It seems that LMWF had a higher area under the curve(AUC_(0–t))and was absorbed more quickly than fucoidan.The estimated bioavailability of LMWF was28.3%in the mice treated with a single dose of 30 mg/kg.In addition,LMWF was found widely spreaded into different tissues following oral administration and the highest concentration was found in kidney at 19.93±7.02μg/g.In this study,we first studied the pharmacokinetics of LMWF,in order to help to understand the function of LMWF.And our results shed light on the potential of development of drugs based on LMWF. | Jiaojiao TAN Yimin SONG Jing WANG Ning WU Yang YUE Quanbin ZHANG | 2023 | Journal of Oceanology and Limnology2023，41，5： | 0 |
| 16 | Mechanism of thermoviscoelasticity driven solid-liquid interface reducing friction for polymer alloy coating显示文摘High-temperature ablation is a common failure phenomenon that limits the service life of the transmission parts on heavy-duty machines used in heavy load,high temperature,high shock conditions due to in-sufficient supply of lubricating oil and grease.Traditional self-lubricating coatings prepared by inorganic,organic or organic-inorganic hybrid methods are prone to be oxidated at high temperatures to lose their friction reducing function,so that it is difficult to meet the engineering requirements of high-temperature lubrication.We design viscoelastic polymer coatings by a high-temperature self-lubricating and wear-resistant strategy.Polytetrafluoroethylene(PTFE,T_(m)=329℃)and polyphenylene sulfide(PPS,T_(g)=84℃,T_(m)=283℃)are used to prepare a PTFE/PPS polymer alloy coating.As the temperature increases from 25 to 300℃,the PTFE/PPS coating softens from glass state to viscoelastic state and viscous flow state,which is owing to the thermodynamic transformation characteristic of the PPS component.Additionally the friction coefficient(μ)decreased from 0.096 to 0.042 with the increasing of temperature from 25 to 300℃.The mechanism of mechanical deformation and surface morphology evolution for the PTFE/PPS coating under the multi-field coupling action of temperature(T),temperature–centrifugal force(T–F_(ω)),temperature–centrifugal force–shearing force(T–F_(ω)–F_(τ))were investigated.The physical model of“thermoviscoelasticity driven solid–liquid interface reducing friction”is proposed to clarify the self-lubricating mechanism determined by the high-temperature viscoelastic properties of polymers.The high-temperature adjusts the viscosity(η)of the coating,increases interface slipping and intensifies shear deformation(τ),reducing the friction coefficient.The result is expected to provide a new idea for designing anti-ablation coatings served in high temperature friction and wear conditions. | Sheng TAN Yimin LUO Junhua YANG Wei WANG Xia LI Baoguang JIA Zhuangzhu LUO Guangan ZHANG | 2023 | Friction2023，11，9： | 0 |
| 17 | Advances in application of sensors for determination of phthalate esters显示文摘Phthalates esters(PAEs) are extensively used as additives for polymers in plastic, particularly in polyvinyl chloride(PVC) and polyethylene terephthalate(PET). These compounds are not part of the polymer chains and can be released easily from products and migrate into beverages and foods that come into direct contact, causing environmental and human health impacts. Simple and rapid detection of such substances is of great significance for ensuring environmental food safety and consumer health. At present, optical sensor and electrochemical sensor detection technologies have been applied to PAEs detection due to their advantages, such as simple, rapid, low cost, high sensitivity, simple operation, portability and high specificity. They can make up for the shortcomings of chromatographic detection technology, such as expensive equipment, cumbersome operation, the need for professional and technical personnel, and difficulty in achieving a large number of sample screening objectives. In this paper, research progress on optical sensors and electrochemical sensors for the detection of phthalates in recent ten years is reviewed and discussed. This is helpful to better understand preparation methods for sensors and their detection mechanisms for phthalates. The review will also be used in developing a more effective trace detection sensor for phthalates. | Chuanxiang Zhang Jie Zhou Tingting Ma Wenfei Guo Dan Wei Yimin Tan Yan Deng | 2023 | Chinese Chemical Letters2023，34，4： | 0 |
| 18 | Multiscale design of stiffening and ROS scavenging hydrogels for the augmentation of mandibular bone regeneration显示文摘Although biomimetic hydrogels play an essential role in guiding bone remodeling,reconstructing large bone defects is still a significant challenge since bioinspired gels often lack osteoconductive capacity,robust mechanical properties and suitable antioxidant ability for bone regeneration.To address these challenges,we first engineered molecular design of hydrogels(gelatin/polyethylene glycol diacrylate/2-(dimethylamino)ethyl methacrylate,GPEGD),where their mechanical properties were significantly enhanced via introducing trace amounts of additives(0.5 wt%).The novel hybrid hydrogels show high compressive strength(>700 kPa),stiff modulus(>170 kPa)and strong ROS-scavenging ability.Furthermore,to endow the GPEGD hydrogels excellent osteoinductions,novel biocompatible,antioxidant and BMP-2 loaded polydopamine/heparin nanoparticles(BPDAH)were developed for functionalization of the GPEGD gels(BPDAH-GPEGD).In vitro results indicate that the antioxidant BPDAH-GPEGD is able to deplete elevated ROS levels to protect cells viability against ROS damage.More importantly,the BPDAH-GPEGD hydrogels have good biocompatibility and promote the osteo differentiation of preosteoblasts and bone regenerations.At 4 and 8 weeks after implantation of the hydrogels in a mandibular bone defect,Micro-computed tomography and histology results show greater bone volume and enhancements in the quality and rate of bone regeneration in the BPDAH-GPEGD hydrogels.Thus,the multiscale design of stiffening and ROS scavenging hydrogels could serve as a promising material for bone regeneration applications. | Yanlin Wu Xuan Li Yimin Sun Xiujun Tan Chenglin Wang Zhenming Wang Ling Ye | 2023 | Bioactive Materials2023，，2： | 0 |
