| 1 | Polarization evolution of vector beams generated by q-plates显示文摘The polarization evolution of vector beams(VBs) generated by q-plates is investigated theoretically and experimentally.An analytical model is developed for the VB created by a general quarter-wave q-plate based on vector diffraction theory.It is found that the polarization distribution of VBs varies with position and the value q.In particular,for the incidence of circular polarization,the exit vector vortex beam has polarization states that cover the whole surface of the Poincarésphere,thereby constituting a full Poincarébeam.For the incidence of linear polarization,the VB is not cylindrical but specularly symmetric,and exhibits an azimuthal spin splitting.These results are in sharp contrast with those derived by the commonly used model,i.e.,regarding the incident light as a plane wave.By implementing q-plates with dielectric metasurfaces,further experiments validate the theoretical results. | WEIXING SHU XIAOHUI LING XIQUAN FU YACHAO LIU YOUGANG KE HAILU LUO | 2017 | Photonics Research2017，5，2： | 7 |
| 2 | Effect of particle size on the transformation kinetics of flue gas desulfurization gypsum to α-calcium sulfate hemihydrate under hydrothermal conditions显示文摘The effect of particle size on the transformation kinetics of flue gas desulfurization (FGD)gypsum to α-calcium sulfate hemihydrate (α-HH)in calcium chloride (CaCl2)solutions was investigated to better guide value-added FGD gypsum use.Gypsum samples from different sources were sieved into several size groups,and their transformation rates were compared.The results showed that using FGD gypsum with a smaller particle size accelerated the transformation to α-HH.The size effect accelerated nucleation kinetics of α-HH rather than its crystal growth rate (that is,the thermodynamic driving force for the transformation changed little with particle size variation).Analysis using a kinetics model revealed that a smaller gypsum particle size lowered the overall activation energy barrier for the transformation.This is because the smaller gypsum particles had a larger relative specific surface area and thus provided more nucleation sites and crystalline defects to promote α-HH nucleation.A smaller particle size of FGD gypsum also gave a higher yield of fine α-HH particles because of the increased incidence of primary and secondary nucleation coupled with attrition.This paper indicates the transformation of FGD gypsum into α-HH could be effectively promoted by regulating FGD gypsum particle size. | Hailu Fu Caiyun Jia Qiaoshan Chen Xueting Cao Xiaomin Zhang | 2018 | Particuology2018，16，5： | 5 |

| 7 | Direct observation and manipulation of hot electrons at room temperature显示文摘In modern electronics and optoelectronics,hot electron behaviors are highly concerned,as they determine the performance limit of a device or system,like the associated thermal or power constraint of chips and the Shockley-Queisser limit for solar cell efficiency.To date,however,the manipulation of hot electrons has been mostly based on conceptual interpretations rather than a direct observation.The problem arises from a fundamental fact that energy-differential electrons are mixed up in real-space,making it hard to distinguish them from each other by standard measurements.Here we demonstrate a distinct approach to artificially(spatially)separate hot electrons from cold ones in semiconductor nanowire transistors,which thus offers a unique opportunity to observe and modulate electron occupied state,energy,mobility and even path.Such a process is accomplished through the scanning-photocurrent-microscopy measurements by activating the intervalley-scattering events and 1D charge-neutrality rule.Findings here may provide a new degree of freedom in manipulating non-equilibrium electrons for both electronic and optoelectronic applications. | Hailu Wang Fang Wang Hui Xia Peng Wang Tianxin Li Juzhu Li Zhen Wang Jiamin Sun Peisong Wu Jiafu Ye Qiandong Zhuang Zaixing Yang Lan Fu Weida Hu Xiaoshuang Chen Wei Lu | 2021 | National Science Review2021，8，9： | 0 |
| 8 | Aldolase A promotes proliferation and G1/S transition via the EGFR/MAPK pathway in non-small cell lung cancer显示文摘Background:Our previous study demonstrated that aldolase A(ALDOA)is overexpressed in clinical human lung squamous cell carcinoma and that ALDOA promotes epithelial-mesenchymal transition and tumorigenesis.The pre-sent study aimed to explore the function of ALDOA in the modulation of non-small cell lung cancer(NSCLC)prolifera-tion and cell cycle progression and the potential mechanism.Methods:ALDOA was knocked down by short hairpin RNA in H520 and H1299 cells.ALDOA was overexpressed with vectors carrying the full-length ALDOA sequence in H1299 and H157 cells.The proliferation capacities were assessed with immunohistochemical staining,Cell Counting Kit-8 and colony formation assays.The cell cycle distribution was examined by flow cytometry,and molecular alterations were determined by western blotting.Cell synchronization was induced with nocodazole.The stability of cyclin D1 mRNA was tested.The pyruvate kinase M2 and ALDOA protein distributions were examined.Aerobic glycolysis was evaluated with Cell Titer-Glo assay,glucose colorimetric assay and lactate colorimetric assay.Results:ALDOA knockdown inhibited the proliferation and G1/S transition in H520 cells.Conversely,ALDOA over-expression promoted the proliferation and G1/S transition in H157 cells.The cell cycle synchronization assay showed that ALDOA expression increased in the G1 phase and G1/S transition.Furthermore,ALDOA knockdown reduced cyclin D1 expression by regulating epidermal growth factor receptor/mitogen-activated protein kinase(EGFR/MAPK)pathway.Similar results were found in H1299 and H157 cells.The inhibition of mitogen-activated protein kinase kinase 1/2 prompted the nuclear distribution of ALDOA.Additionally,ALDOA knockdown reduced nuclear distribution of PKM2,the extracellular lactate and intracellular adenosine triphosphate concentrations and elevated the extracellular glucose concentration.Conclusions:ALDOA contributed to activation of the EGFR/MAPK pathway,thus promoting cyclin D1 expression and enhancing proliferation and G1/S transition in NSCLC.Additionally,ALDOA facilitated NSCLC aerobic glycolysis. | Hailu Fu Huijun Gao Xiaoyu Qi Lei Zhao Donghua Wu Yuxin Bai Huimin Li Xuan Liu Jun Hu Shujuan Shao | 2018 | Cancer Communications2018，38，1： | 0 |
