| 1 | Iontophoretic Delivery of Riboflavin into the Rabbit Cornea:a Primary Study显示文摘Purpose: To determine the penetrability of riboflavin into the corneal stroma by iontophoresis and to compare the permeability effects of different solvents.Methods: Twenty rabbits were randomly divided into four groups: a group that received 0.1% riboflavin-balanced salt solution(BSS) by iontophoresis, a group that received 0.1%riboflavin-saline solution by iontophoresis, a group that received 0.1% riboflavin-distilled water solution by iontophoresis, and a control group that received classical riboflavin instillation after corneal de-epithelialization. The degree of yellowing of the de-epithelialized corneal stromal button from each rabbit was compared.Results: The yellow color scores for the corneal stromal buttons in the three iontophoresis groups were compared with those of control group. Iontophoretic delivery of a 0.1% riboflavin-distilled water solution yielded similar yellow changes in the corneal stromal button when compared with classical riboflavin instillation after de-epithelialization. However, the other two solvents did not sufficiently enhance the permeability of riboflavin.Conclusion: Riboflavin can effectively penetrate into the corneal stroma to saturation levels by iontophoresis. Using distilled water as the solvent can promote penetrability. | Na Li Xiujun Peng Zhengjun Fan Yu Xia | 2014 | Eye Science2014，29，1： | 9 |

| 10 | Thermal stability and sputtering resistance under irradiation of yttria dispersed ferrum films显示文摘Oxide dispersion strengthened (ODS) steels are considered as potential candidates for high temperature applications in fusion reactors be-cause of their excellent thermal creep behavior. In the present work, the double-target magnetron co-sputtering method was recommended to prepare yttria dispersed ferrum films. Vacuum annealing and ion irradiation were carried out to study the surface topography and structural features of the prepared yttria dispersed ferrum samples. Experiments proved that while the yttria doping ratio in the ferrum film increases, the recrystallization temperature of the film will be enhanced and the sputtering damage by Xenon ion irradiation will be lowered. The sput-tering resistance of the obtained films would be improved with the growing of grains under vacuum annealing. | LI Zhengcao YU Xiaoyi MIAO Wei ZHANG Zhengjun | 2011 | Rare Metals2011，30，3： | 0 |
| 11 | Variation in Central Corneal Thickness during Open- or Closed-Eye Riboflavin Instillation for Corneal Collagen Cross-linking显示文摘Purpose:To assess the effect of having an open or closed eye on the variation in central corneal thickness during riboflavin instillation for corneal collagen cross-linking (CXL).Methods:.Thirty eyes of 15 New Zealand White rabbits underwent an in vivo anterior segment optical coherence tomography (OCT) examination at 0,10,20,and 30 min after riboflavin instillation on the de-epithelialized corneal surface.Each eye of every rabbit was randomly placed into one of two different treatment groups(open-eye or closed-eye)during the instillation;.the examinations were performed one after the other.After instillation for 30 min,the changes in the corneal stroma and anterior chamber were observed by slit lamp.Results:.A significant decrease in the central corneal thickness(CCT).was demonstrated during riboflavin instillation;.the variations were smaller in the measurements performed with the eye closed than with the eye open.(81.36±15.13μm and129.20±12.05μm respectively)..Both methods turned the corneal stroma and anterior chamber yellow.Conclusion:Keeping the eye closed during riboflavin instillation reduced the decrease in the CCT..The same yellow change in the corneal stroma and anterior chamber occurred,but the exposure time of the ocular surface was shorter.Therefore,.keeping the eye closed was a more effective and safer method than keeping the eye open. | Na Li Xiujun Peng Zhengjun Fan Xu Pang Yu Xia | 2013 | Eye Science2013，28，4： | 0 |
| 12 | Influence of vacuum annealing and irradiation on magnetic properties of Fe-3% Y_2O_3 films显示文摘Yttria (Y) dispersed ferrum (Fe) films were prepared by a double-target magnetron co-sputtering method. Vacuum annealing and xenon ion irradiation were conducted to investigate the influence on the magnetic and mechanical properties of the films. The crystal grain growth mechanism and second phase precipitation mechanism were conducted simultaneously in the vacuum annealing process. These two effects led to an opposite variation of nano-hardness and coercivity in the films. Xenon ion irradiation played a role in rapid annealing, which also affected the magnetic performance of the yttria dispersed ferrum films. | LI Zhengcao YU Xiaoyi MIAO Wei ZHANG Zhengjun | 2011 | Rare Metals2011，30，5： | 0 |
| 13 | Development and application of high-precision multifunction astronomical plate digitizers in China显示文摘Before charge-coupled device detectors became widely employed in observational astronomy,for more than a hundred years,the main detection method was photography on astronomical glass plates.Recently,in order to preserve these historical data and maintain their usability,the International Astronomical Union has appealed to all countries for global digitization of astronomical plates by developing or adopting advanced digitization technology.Specialized digitizers with high precision and high measuring speed represent key equipment for this task.The Shanghai Astronomical Observatory and the Nishimura Co.,Ltd in Japan cooperated between 2013 and 2016 to develop the first Chinese high-precision astronomical plate digitizer,which was then used for complete digitization of all nighttime-observation astronomical plates in China.Then,in 2019–2021,the Shanghai Astronomical Observatory independently developed new models of plate digitizers that enabled countries such as Uzbekistan and Italy to digitize their astronomical plates.Additionally,a new high-precision and multifunction digitizer was also used to digitize valuable microscope slides from the Shanghai Natural History Museum,providing a successful example of cross-domain application of high-precision digitization technology. | Meiting Yang Yong Yu Liangliang Wang Zhengjun Shang Changshun Liu Lixin Zheng Zhendong Chen Jing Yang Dongmei Da Shan Dong Shiyin Shen Zhenghong Tang Jianhai Zhao | 2024 | Astronomical Techniques and Instruments2024，1，1： | 0 |
| 14 | A Forward-Secure Multi-Receiver Signcryption Scheme显示文摘In order to protect historical ciphertext when the private key leaked in the broadcasting system,the forward-secure multi-receiver signcryption scheme is designed based on the generic graded multilinear mapping encoding structure,which effectively prevents illegal access from intruder to the ciphertext in the past time period when the private key in current time period is revealed.Through the generalization of the existing multilinear mapping encoding system,it proposes the generic graded multilinear mapping encoding structure and the generic graded decision Diffie-Hellman problem.Because of the generic graded multilinear mapping encoding system adopted,almost all candidate multilinear mapping encoding systems can automatically adapt to our scheme.Under the assumption of generic graded decision Diffie-Hellman problem,it has proved that the scheme has the information confidentiality and unforgeability in the current time period.After putting forward the security model of forward-secure multi-receiver signcryption scheme,and under the assumption of generic graded decision Diffie-Hellman problem,it has proved that the scheme has the message forward-confidentiality and forward-unforgeability.Compared with other forward-secure public key encryption schemes,the relationship between our scheme and time periods is sub-linear,so it is less complex. | Zhimin Yu Zhengjun Jing Hua Yang Chunsheng Gu | 2016 | Journal of Harbin Institute of Technology(New Series)2016，23，5： | 0 |
| 15 | CRYPTANALYSIS OF AN EXTENDED MQ SIGNATURE SYSTEM HTTM显示文摘Since Multivatriate Quadratic(MQ)-based Public Key Cryptosystem(MPKC)has been one of the hot research fields of post-quantum cryptography,it becomes important to analyze the security of new MPKC schemes.Wang et al.proposed a novel multivariate signature scheme with Hash-based Tame Transformation and Minus(HTTM)in 2011.For this extended MQ-based signature,we can transform it into an SFLASH variant by splitting and merging HT transformation,and solve an equivalent private key corresponding to the public key of HTTM.Thus,the adversary can forge legitimate signature for any message by using this equivalent private key. | Jing Zhengjun Yu Zhimin Gu Chunsheng Wu Fangsheng Zhao Xiaorong | 2013 | Journal of Electronics(China)2013，30，5： | 0 |
| 16 | Research on the Marine Antifouling Ability and Mechanism of Acrylate Copolymers and Marine Coatings Based on a Synergistic Effect显示文摘Marine biofouling is an urgent global problem in the process of ocean exploitation and utilization.In our work,a series of zinc-based acrylate copolymers(ACZn-x)were designed and synthesized using benzoic acid,zinc oxide(ZnO)and a random quaternion copolymer consisting of ethyl acrylate(EA),butyl acrylate(BA),acrylic acid(AA)and methacrylic acid(MAA)by free radical polymerization and dehydration condensation.The ACZn-x with a zinc benzoate side chain is able to hydrolyze in natural seawater under static conditions,resulting in the formation of a smooth surface.We investigated and confirmed the antifouling(AF)behavior of ACZn-x in the laboratory and revealed that they have better antibacterial(86%for S.aureus and 72%for E.coli)and anti-algal(≥60.1%for N.closterium and≥67.5%for P.subcordiformis)activities.We also assessed the marine AF properties of ACZn-x and corresponding coatings in Qingdao,China;the ACZn-x exhibited ideal AF properties with little silt and biological mucosa adhered to the ACZn-x surface after 6 months,and corresponding coatings exhibited little biofouling after 16 months in the ocean.Importantly,possible AF mechanisms were further proposed at the cellular level.These results could be helpful for the development and application of effective AF coatings. | ZHOU Wenjun ZHOU Yu NI Chunhua YU Liangmin YUAN Zhengjun LI Changcheng YAN Xuefeng | 2023 | Journal of Ocean University of China2023，22，3： | 0 |
