| 1 | Foraging areas of Rousettus leschenaulti on the Hainan Island of China显示文摘We investigated the foraging area of three individuals (1 female and 2 males) of Rousettus leschenaulti (Chiroptera,Pteropodidae) in suburban Haikou City, Hainan Province, South China from November 2005 to January 2006 using radio telemetry.These animals left the daytime roosting sites about 90 min after sunset with no significant difference in departure time betweenthe male and female bats. The average active times were 391.8 min for males and 533.7 min for the female, respectively.By reconstructing 93 radio-telemetry recording positions, we found that the long axis of foraging area of the bats ranged from7.45 to 11.70 km. The foraging area of the female (3867 ha) was larger than that of the males (1138 ha), and there was overlapbetween the foraging areas of different individuals. These bats usually kept the same flight routes across a few successive daysfrom the daytime roosting site to the foraging areas. Our findings suggested that female R. leschenaulti may explore a larger foragingarea than males. No obvious territorial behaviors were observed in our studied area. | Zhanhui TANG Zhong CHEN Jie MA Guangjian ZHU Xunfeng MA Lianxi SHENG Yuchun LI | 2010 | Current Zoology2010，56，4： | 2 |
| 2 | Bioinspired Anti-Icing Hydrogel Enabled by Ice-Nucleating Protein显示文摘Ice-nucleating proteins(INPs)are the most effective ice-nucleating agents that play a significant role in preventing freeze injuries in freeze-tolerant organisms.INPs promote ice nucleation in the extracellular space,harvesting water from cells due to the low vapor pressure of ice compared with water,thereby protecting freeze-tolerant organisms from intracellular freezing.The antifreeze mechanism of INPs offers a unique opportunity to inhibit large-scale freezing by localized control of ice formation,with valuable enlightenment in anti-icing material sciences.By learning from nature,we transferred the excellent ice nucleation-facilitating capability of INPs along with an antifreeze concept of spatially controlled ice nucleation to anti-icing material design,fabricating icephobic coatings that consisted of patterned hydrogel-encapsulated INP(PHINP).The ice patterns were templated by patterned PHINPs via the tuning of ice nucleation so that the ice coverage fraction could be controlled by<30%on almost all PHINP-coated surfaces.Combining PHINP with solar-thermal conversion surfaces endowed the composite coatings with high anti-icing performances at any time of the day. | Zhanhui Wang Baixue Lin Siyu Sheng Sicong Tan Pengchao Wang Yong Tao Zhang Liu Zhiyuan He Jianjun Wang | 2022 | CCS Chemistry2022，4，1： | 0 |
| 3 | Experimental Study of Shrinkage Displacements of Points on Injection Molded Parts显示文摘The existing research on shrinkage of the injection molded plastic part mainly focuses on various shrinkage ratios of the part dimensions,and the relevant experimental studies belong to mere dimension measurement after demoulding.Obviously,measuring after the plastic part is demoulded from the cavity can not offer shrinkage displacements of points on the plastic part.However,shrinkage displacements of points on an injection molded plastic part are essential for exposing the inner relation among shrinkage ratios of various dimensions of the part.So visualization of the in-mold plastic part which can indicate the location relationship between the part and the cavity is needed.In this paper,a visual injection mold was fabricated by adopting the half mold structure and light transmission manner.With the visual mold,in-mold shrinkage images of injection molded plastic parts were photographed after the plastic part stayed in the injection mold for 24 h.By means of digital image processing of the in-mold shrinkage images,the experimental data of shrinkage displacements of points on injection molded parts were researched.From the experimental data,it is found that shrinkage directions of points on an injection molded part are related with both positions of the gate and of the part centroid,and either the gate or the centroid will exert more influence on the shrinkage direction of some point which is closer.Furthermore,some point at the later filled area has more shrinkage distance than the point at the earlier filled area.Combination of shrinkage directions and shrinkage distances of points on an injection molded part determine shrinkage ratios for various dimensions of the part,and shrinkage directions are more influential to shrinkage ratios of dimensions.This experimental research of shrinkage displacements offers a unique approach to understand the shrinkage principles of injection molded parts. | ZHU Tieli WANG Minjie SHENG Zhanhui | 2010 | Chinese Journal of Mechanical Engineering2010，23，5： | 0 |
