| 1 | An organic light-emitting devices of highly efficient white phosphor using an electron/exciton blocker显示文摘Highly efficient white phosphorescent organic light-emitting devices (WOLEDs) was fabricated using an electron/exciton blocker. The device structure is ITO/2T-NATA(25 nm)/ NPBX(25-dnm)/CBP:5%Ir(ppy)3:0.5%Rubrene(8 nm)/NPBX(dnm)/ DPVBi(30 nm)/TPBi(20 nm)/Alq(10nm)/LiF(1nm)/Al, in which N,N '-bis- (1-naphthyl)- N,N '-diphenyl -1, 1 '- bi- phenyl-4,4 '-diamine (NPBX) functions as a hole transport layer and electron/exciton blocker, 4,4,N,N '- dicarbazolebiphenyl (CBP) is host, 4,4'-bis(2,2 -diphenyl vinyl)-1,1 '-biphenyl (DPVBi) is blue fluorescent dye, 5,6,11, 12,-tetraphenylnaphthacene (rubrene) is fluorescent dye, factris (2-phenylpyridine) iridium (Ir(ppy)3) is phosphorescent sensitizer and tris(8-hydroxyquinoline) aluminum (Alq3) is an electron transport layer. The WOLEDs have obtained white light emission by adjusting the thickness of NPBX , when the concentration of Ir(ppy)3 is 5-wt% and rubrene is 0.5-wt%, respectively, the thickness of the doped emissive layer is 8 nm, the WOLEDs show a maximum luminous efficiency is 11.2 cd/ A with d of 10 nm at 7 V and a maximum luminance of 28170 cd/m2 at 17 V, the CIE coordinates is (0.37.0.42), which is in white region. | JIANG Wen-long , DING Gui-ying, WANG Jin,WANG Jing , WANG Li-zhong , CHANG Xi,HAN Qiang , WANG Hong-mei , and ZHAO Xiao-hong College of information Technology , Jilin Normal University, Siping 136000,China | 2008 | Optoelectronics Letters2008，4，1： | 7 |
| 2 | Coordination of Copper Ion Crosslinked Composite Beads with Enhanced Toxins Adsorption and Thin‑Film Nanofbrous Composite Membrane for Realizing the Lightweight Hemodialysis显示文摘In this study,a novel copper ion(Cu^(2+))crosslinked composites beads with components of sodium alginate(SA)as gel matrix and UiO-66-(COOH)_(2) metal organic framework(MOF)nanoparticle as functional fller could efectively adsorb toxins in dialysate.The maximum adsorption capacity of the optimized composite beads(Cu-SA/U-4)for creatinine reached 125.0 mg/g with a positive synergistic efect based on Langmuir isotherm model and pseudo-second-order kinetic model,which was 1.75 times and 1.50 times that of single component beads(Cu-SA)and UiO-66-(COOH)_(2) nanoparticle respectively.Furthermore,when the dialysis performance using thin-flm nanofbrous composite(TFNC)membrane was comparable,introduction of Cu-SA/U-4 beads into the dialysate allowed the volume of dialysate reduced to one-tenth of that without beads.Therefore,the coordination of such highly efcient adsorbent beads and TFNC dialysis membrane can economize the usage of the dialysate and contributes to realize lightweight hemodialysis.More importantly,we not only prepared a kind of composite bead via carefully designed strategy,but also proposed widely applicable idea of using adsorbents in combination with dialysis membrane to realize lightweight or miniaturized hemodialysis. | Siping Ding Peiyun Li Tonghui Zhang Xuefen Wang | 2022 | Advanced Fiber Materials2022，4，3： | 1 |
| 3 | Coordination of thin-film nanofibrous composite dialysis membrane and reduced graphene oxide aerogel adsorbents for elimination of indoxyl sulfate显示文摘The protein-bound uremic toxins,represented by indoxyl sulfate(IS),have been associated with the progression of chronic kidney disease and the development of cardiovascular disease in the presence of impaired renal function.Herein,we proposed a novel strategy of thin-film nanofibrous composite(TNFC)dialysis membrane combined with reduced graphene oxide(rGO)aerogel adsorbents for clinical removal of IS as well as high retention of proteins.The TFNC membrane was prepared by electrospinning in conjunction with coating-reaction method and proved to have good selectivity and permeability.To further improve the removal rate of toxins,we used a medium hydrothermal method following by freeze-drying treatment to obtain the r GO aerogel adsorbents.It exhibited excellent adsorption for IS with a maximum adsorption capacity of 69.40 mg·g^(-1)throughπ-πinteraction and hydrogen bonding interaction based on Langmuir isotherm models.Time-dependent absorption experiments showed that it reached adsorption equilibrium within 4 h,which was matched with the hemodialysis time.The coordination was significantly exhibited by introducing r GO aerogel blocks into the dialysate for absorbing the diffused free IS during hemodialysis.Taking the advantages of the TFNC dialysis membrane and the rGO aerogel,the volume of dialysate for hemodialysis was only one-tenth of that without adsorbent blocks but with very comparable dialysis performance(the clearance of IS at 51.8%and the retention of HSA over 98%),which could lighten conventional hemodialysis effectively and be benefit to realize the miniaturization of the hemodialysis equipment.Therefore,the coordination of the TFNC dialysis membrane and rGO aerogel adsorbents would open a new path for the development of portable artificial kidney. | Yuanyuan Jin Siping Ding Peiyun Li Xuefen Wang | 2022 | Chinese Journal of Chemical Engineering2022，35，9： | 0 |
| 4 | Efficient Processing of Multi-way Joins Using MapReduce显示文摘Multi-way join is critical for many big data applications such as data mining and knowledge discovery. Even though lots of research have been devoted to processing multi-way joins using MapReduce, there are still several problems in general to be further improved, such as transferring numerous unpromising intermediate data and lacking of better coordination mechanisms. This work proposes an efficient multi-way joins processing model using MapReduce, named Sharing-Coordination-MapReduce (SC-MapReduce), which has the functions of sharing and coordination. Our SC-MapReduce model can filter the unpromising intermediatedata largely by using the sharing mechanism and optimize the multiple tasks coordination of multi-way joins. Extensive experiments show that the proposed model is efficient, robust and scalable. | Linlin Ding Siping Liu Yu Liu Aili Liu Baoyan Song | 2015 | 国际计算机前沿大会会议论文集2015，，1： | 0 |
