| 1 | White-light emitting single-phase phosphor La_3Si_6N_(11):Dy^(3+),Tb^(3+):Color tunable emission, thermal stability and energy transfer process显示文摘A novel white-light emitting single-phase phosphor La_3 Si_6 N_(11):Dy^(3+),exhibiting two emission peaks centering at 475 and 575 nm, was prepared via conventional solid-state reactions. The structure and morphology of La_3 Si_6 N_(11):Dy^(3+)/Tb^(3+) were investigated by X-ray diffraction(XRD) and scanning electron microscopy(SEM). The emission colors can be tuned from white to yellow-green through increasing the Tb^(3+) concentration in La_3 Si_6 N_(11):Dy^(3+),Tb^(3+), The mechanism of energy transfer(ET) from Dy^(3+) to Tb^(3+) is confirmed according to the excitation,emission spectra and decay lifetimes curve. The temperaturedependent luminescence measurements of La_(2.83)Si_6 N_(11):0.1 Dy^(3+),0.07 Tb^(3+) were also performed, and a good thermal stability is shown, suggesting superior properties for the application as white lightemitting diodes(w-LEDs) phosphor. | Yuanhong Liu Yuan Xue Ronghui Liu Mingyue Chen Guantong Chen Chunpei Yan Xia Zhang Yu'nan Zhou Wei Gao Xiaole Ma | 2019 | Journal of Rare Earths2019，37，4： | 5 |
| 2 | Tailoring the Meso-Structure of Gold Nanoparticles in Keratin-Based Activated Carbon Toward High-Performance Flexible Sensor显示文摘Flexible biosensors with high accuracy and reliable operation in detecting pH and uric acid levels in body fluids are fabricated using well-engineered metaldoped porous carbon as electrode material.The gold nanoparticles@N-doped carbon in situ are prepared using wool keratin as both a novel carbon precursor and a stabilizer.The conducting electrode material is fabricated at 500℃ under customized parameters,which mimics A-B type(two different repeating units) polymeric material and displays excellent deprotonation performance(pH sensitivity).The obtained pH sensor exhibits high pH sensitivity of 57 mV/pH unit and insignificant relative standard deviation of 0.088%.Conversely,the composite carbon material with sp^2 structure prepared at 700℃ is doped with nitrogen and gold nanoparticles,which exhibits good conductivity and electrocatalytic activity for uric acid oxidation.The uric acid sensor has linear response over a range of 1-150 μM and a limit of detection 0.1 μM.These results will provide new avenues where biological material will be the best start,which can be useful to target contradictory applications through molecular engineering at mesoscale. | Aniruddha BPatil Zhaohui Meng Ronghui Wu Liyun Ma Zijie Xu Chenyang Shi Wu Qiu Qiang Liu Yifan Zhang Youhui Lin Naibo Lin Xiang Yang Liu | 2020 | Nano-Micro Letters2020，12，9： | 3 |
| 3 | Carbon interstitial defects causing emission red shift in YAG:Ce phosphor:First-principles calculation显示文摘Y_3 Al_5 O_(12):Ce3+ is the most famous phosphor material due to its excellent photolumincent properties.Here,through first-principles calculation,the effect of carbon interstitial defects on Y_3 Al_5 O_(12):Ce3+phosphor was investigated. It is found that the carbon interstitials tend to occupy the next-nearest sites of Ce^(3+) ion in Y_3 Al_5 O_(12):Ce3+ lattice. Specially,these interstitial defects can shorten the Ce3+-O^(2-) bond length, leading to a larger crystal field splitting of 5 d orbital of the Ce^(3+) atom and bigger 5 d centroid shift.These two factors cause the emission spectrum of Y_3 Al_5 O_(12)(C):Ce^(3+) red shift compared with that of Y_3 Al_5 O_(12):Ce3+. Moreover, with our comparison experiment, we find that the Y_3 Al_5 O_(12)(C):Ce3+ has an obvious red shift compared with that of Y_3 Al_5 O_(12):Ce^(3+) system,which is in accord with our first principles calculation. Our work systematically investigates the impact of the carbon interstitial defect on Y_3 Al_5 O_(12):Ce^(3+),and provides a new route to tune the emission spectrum in Y_3 Al_5 O_(12):Ce^(3+). | Yaling Zheng Weidong Zhuang Xianran Xing Ronghui Liu Yanfeng Li Yuanhong Liu Yunsheng Hu Xiaoxia Chen Lei Chen Xiaole Ma | 2018 | Journal of Rare Earths2018，36，12： | 1 |

| 5 | An Optimal Resources Configuration Scheme for Caching-Based Content Distribution in BackhaulLimited Small Cell Networks显示文摘In this paper, we study the problem of resource allocation in small cell networks with distributed caching, that is, how to divide the spectrum resources for backhaul and access in order to improve network performance. We formulate our concerned problem by using multi-dimensional Markov model. Our problem considers that each user may access multiple small cell base stations. We conduct simulation experiments to evaluate the performance of our proposed resource allocation scheme. Our simulation results show that the appropriate spectrum resource allocation is important to improve network performance. | Jingfeng Cai Ronghui Hou Yinghong Ma | 2018 | China Communications2018，15，1： | 1 |
| 6 | Downregulation of nc886 contributes to prostate cancer cell invasion and TGFβ1-induced EMT显示文摘Epithelial-to-mesenchymal transition (EMT) activation is important in cancer progression and metastasis. Evidence indicates that nc886 is a representative Pol III gene that processes microRNA products via Dicer and further downregulates its target gene transforming growth factor- β1 (TGF-β1), which is the most prominent inducer of EMT in prostate cancer (PC). Consistent with the previous literature, we found that nc886 downregulation was strongly associated with metastatic behavior and showed worse outcomes in PC patients. However, little is known about the association between nc886 and the EMT signaling pathway. We developed a PC cell model with stable overexpression of nc886 and found that nc886 changed cellular morphology and drove MET. The underlying mechanism may be related to its promotion of SNAIL protein degradation via ubiquitination, but not to its neighboring genes, TGFβ-induced protein (TGFBI) and SMAD5, which are Pol II-transcribed. TGF-β1 also override nc886 promotion of MET via transient suppression the transcription of nc886, promotion of TGFBI or increase in SMAD5 phosphorylation. Both nc886 inhibition and TGFBI activation occur regardless of their methylation status. The literature suggests that MYC inhibition by TGF-β1 is attributed to nc886 downregulation. We incidentally identified MYC-associated zinc finger protein (MAZ) as a suppressive transcription factor of TGFBI, which is controlled by TGF-β1. We elucidate a new mechanism of TGF-β1 differential control of Pol II and the transcription of its neighboring Pol III gene and identify a new EMT unit consisting of nc886 and its neighboring genes. | Ronghui Yang Lingkun Zuo Hui Ma Ying Zhou Ping Zhou Liyong Wang Miao Wang Mahrukh Latif Lu Kong | 2022 | Genes & Diseases2022，9，4： | 1 |
