| 1 | Stepwise-Nanocavity-Assisted Transmissive Color Filter Array Microprints显示文摘Visible-light color flters using patterned nanostructures have attracted much interest due to their various advantages such as compactness,enhanced stability,and environmental friendliness compared with traditional pigment or dye-based optical flters.While most existing studies are based on planar nanostructures with lateral variation in size,shape,and arrangement,the vertical dimension of structures is a long-ignored degree of freedom for the structural colors.Herein,we demonstrate a synthetic platform for transmissive color flter array by coordinated manipulations between height-varying nanocavities and their lateral flling fractions.Te thickness variation of those nanocavities has been fully deployed as an alternative degree of freedom,yielding vivid colors with wide gamut and excellent saturation.Experimental results show that the color-rendering capability of the pixelated nanocavities can be still retained as pixels are miniaturized to 500 nm.Crosstalk between closely spaced pixels of a Bayer color flter arrangement was calculated,showing minimal crosstalk for 1μm2 square subpixels.Our work provides an approach to designing and fabricating ultracompact color flter arrays for various potential applications including stained-glass microprints,microspectrometers,and high-resolution image sensing systems. | Yasi Wang Mengjie Zheng Qifeng Ruan Yanming Zhou Yiqin Chen Peng Dai Zhengmei Yang Zihao Lin Yuxiang Long Ying Li Na Liu Cheng-Wei Qiu Joel K.W.Yang Huigao Duan | 2018 | Research2018，，1： | 8 |

| 3 | The Effect of Bamboo Charcoal Application on Soil Nutrients and Heavy Metals in Rice显示文摘Soil heavy metal pollution is becoming more and more serious.Biomass charcoal application can play an important role in alleviating the toxicity of heavy metals in soils.Compared with other biochar,bamboo charcoal has more unique properties and may have a unique effect on heavy metal pollution.Zhejiang Province of Southeastern China is rich in bamboo resources.However,few studies related to bamboo charcoal application for heavy metal remediation in farmland were reported.In this study,four treatments with different amounts of bamboo charcoal application were set up through a field experiment,namely BC0(no bamboo charcoal application),BC1(2500 kg⋅ha^(−1)),BC2(5000 kg⋅ha^(−1)),and BC3(10000 kg⋅ha^(−1)),and each treatment was replicated three times.The results showed that(1)The application of bamboo charcoal significantly increased the soil pH and organic matter content.Compared with BC0,the pH and organic content of BC3 increased by 7.4%and 17.4%(P<0.05)respectively.(2)The HCl-extractable Cd content of paddy soil in the BC1 treatment was significantly lower than other treatments(P<0.05),and decreased by 15.3%,compared with BC0.The soil HCl-extractable Zn and Cu content did not differ significantly between treatments(P>0.05).(3)With the increase of bamboo charcoal application,the Cd content in rice gradually decreased,the BC3 treatment significantly decreased by 39.0%(P<0.05),and the Zn and Cu contents in rice did not differ significantly between treatments(P>0.05),compared with BC0.(4)Soil pH,organic matter and Cd in rice seeds were significantly negatively correlated(P<0.01).The heavy metal content in rice does not change with the change of heavy metal content with HCl-extractable state in soil.It means bamboo charcoal does not reduce heavy metal content in rice by simply declining the heavy metal content with HCl-extractable state.The mechanism of action is relatively complicated,and further study is needed. | Guangyue Cai Juanli Tu Songhao Li Yifei Ruan Qifeng Wu Jiasen Wu | 2022 | Phyton-International Journal of Experimental Botany2022，91，6： | 0 |
