| 1 | 1980~2050年大气沉降导致中国森林土壤酸化显示文摘稳定的土壤pH对维持生态系统的结构和功能至关重要.中国是酸沉降最严重的区域,长期高剂量的酸沉降可能将导致土壤pH显著降低,甚至造成严重的区域生态环境问题.然而,目前有关酸沉降对中国森林土壤酸化的影响还未见报道.本文利用土壤酸化过程模型结合长期监测的大气沉降、植物-土壤养分含量数据、社会发展、气候和污染控制情景,评估并预测1980~2050年间大气沉降导致的森林土壤酸化趋势.结果表明:1980~2019年,表层土壤pH和碱基饱和度分别平均下降0.56和18%.氮沉降的贡献小于硫沉降,但它仍在持续增加.预测结果表明,2020~2050年可持续发展结合高强度减排情景相较于不采取措施情景可使土壤pH下降减少60%,但仍不能逆转土壤pH降低.因此,在未来不仅需要继续控制酸性污染物的排放,还需要加强氮的控制,并在土壤酸化高风险区采取相应恢复措施. | Qiongyu Zhang Jianxing Zhu Qiufeng Wang Li Xu Mingxu Li Guanhua Dai Jan Mulder Yue Xi Nianpeng He | 2022 | Science Bulletin2022，67，9： | 2 |
| 2 | Advances in inorganic nanoparticles trapping stiffness measurement:A promising tool for energy and environmental study显示文摘Optical tweezers system has emerged as an efficient tool to manipulate tiny particles in a non-invasive way.Trapping stiffness,as an essential parameter of an optical potential well,represents the trapping stability.Additionally,trapping inorganic nanoparticles such as metallic nanoparticles or other functionalized inorganic nanoparticles is important due to their properties of good stability,high conductivity,tolerable toxicity,etc.,which makes it an ideal detection strategy for bio-sensing,force calculation,and determination of particle and environmental properties.However,the trapping stiffness measurement(TSM)methods of inorganic nanoparticles have rarely been analyzed and summarized.Here,in this review,the principle and methods of TSM are analyzed.We also systematically summarize the progress in acquiring inorganic particles trapping stiffness and its promising applications.In addition,we provide prospects of the energy and environment applications of optical tweezering technique and TSM.Finally,the challenges and future directions of achieving the nanoparticles trapping stiffness are discussed. | Xiaolin Chen Jiajie Chen Jianxing Zhou Xiaoqi Dai Yuhang Peng Yili Zhong Ho-Pui Ho Bruce Zhi Gao Han Zhang Junle Qu Yonghong Shao | 2023 | Energy Reviews2023，2，2： | 1 |

| 4 | Low-temperature optothermal nanotweezers显示文摘Optical tweezers that rely on laser irradiation to capture and manipulate nanoparticles have provided powerful tools for biological and biochemistry studies.However,the existence of optical diffraction-limit and the thermal damage caused by high laser power hinder the wider application of optical tweezers in the biological field.For the past decade,the emergence of optothermal tweezers has solved the above problems to a certain extent,while the auxiliary agents used in optothermal tweezers still limit their biocompatibility.Here,we report a kind of nanotweezers based on the sign transformation of the thermophoresis coefficient of colloidal particles in low-temperature environment.Using a self-made microfluidic refrigerator to reduce the ambient temperature to around 0℃in the microfluidic cell,we can control a single nanoparticle at lower laser power without adding additional agent solute in the solution.This novel optical tweezering scheme has provided a new path for the manipulation of inorganic nanoparticles as well as biological particles. | Jianxing Zhou Xiaoqi Dai Yuhang Peng Yili Zhong Ho-Pui Ho Yonghong Shao Bruce Zhi Gao Junle Qu Jiajie Chen | 2023 | Nano Research2023，16，5： | 1 |
| 5 | CRISPR-powered optothermal nanotweezers:Diverse bio-nanoparticle manipulation and single nucleotide identification显示文摘Optothermal nanotweezers have emerged as an innovative optical manipulation technique in the past decade,which revolutionized classical optical manipulation by efficiently capturing a broader range of nanoparticles.However,the optothermal temperature field was merely employed for in-situ manipulation of nanoparticles,its potential for identifying bio-nanoparticles remains largely untapped.Hence,based on the synergistic effect of optothermal manipulation and CRIPSR-based bio-detection,we developed CRISPR-powered optothermal nanotweezers(CRONT).Specifically,by harnessing diffusiophoresis and thermo-osmotic flows near the substrate upon optothermal excitation,we successfully trapped and enriched DNA functionalized gold nanoparticles,CRISPR-associated proteins,as well as DNA strands.Remarkably,we built an optothermal scheme for enhancing CRISPR-based single-nucleotide polymorphism(SNP)detection at single molecule level,while also introducing a novel CRISPR methodology for observing nucleotide cleavage.Therefore,this innovative approach has endowed optical tweezers with DNA identification ability in aqueous solution which was unattainable before.With its high specificity and feasibility for in-situ bio-nanoparticle manipulation and identification,CRONT will become a universal tool in point-of-care diagnosis,biophotonics,and bio-nanotechnology. | Jiajie Chen Zhi Chen Changle Meng Jianxing Zhou Yuhang Peng Xiaoqi Dai Jingfeng Li Yili Zhong Xiaolin Chen Wu Yuan Ho-Pui Ho Bruce Zhi Gao Junle Qu Xueji Zhang Han Zhang Yonghong Shao | 2023 | Light(Science & Applications)2023，12，12： | 0 |
