尝试采用三种方式来平衡载流子的浓度,以提高量子点发光二极管(QLED)的外量子效率等性能:在正装结构(ITO/HIL/HTL/QD/ETL/EIL/金属阴极)的QLED的发光层和电子传输层中间插入超薄聚甲基丙烯酸甲脂(PMMA)电子阻挡层;在空穴注入和传输层方面,通过使用更加优化的HIL等来提高空穴注入和传输几率;在QD发光层方面,用短链配体来置换量子点的长链配体以增加载流子向量子点发光层中的传输效率等。在进行量子点配体交换的同时带来了量子点在正交溶剂中的可溶性优势,有利于QLED器件的全溶液法制备。

针对含高浓度硫氰酸盐的废水/废液,采用高效的物化技术实现化学转化,避免生物过程因毒性抑制所需要的稀释作用,作为预处理工艺提供厌氧氨氧化的水质条件.以配制的硫氰酸盐模拟废水作为研究对象,采用自主搭建的脉冲电晕放电(PCD)装置,从构建厌氧氨氧化适配条件的目的出发,考察了不同pH条件下含氮污染物经PCD处理随时间的动态转化规律,以及SCn.--n.解副产物(SO4^2-和HCO^3-浓度)对n.4^+-n.解的影响,并拟合了不同条件下n.4^+-n.降解动力学.结果表明,PCD技术利用原位产生的O3和·OH能氧化包括SCn.--n.n.4^+-n.内的还原态含氮化合物为n.3^--n.pH的增高有利于氧化反应的进行;反应过程中产生的SO4^2-和HCO3^-对n.4^+-n.氧化具有显著的抑制作用,HCO3^-的抑制效应要高于SO4^2-.研究表明,对于高SCn.-废水的处理,PCD技术可作为厌氧氨氧化工艺的预处理技术,在规避毒性抑制与构造水质特征方面表现出优越性.

Surgical treatmen.s of acute myocardial in.arction.(MI) possess a high clin.cal effectiven.ss, but there are fixed limitation., related to the patien.’s state, which are limited by medical resources an. organ.zation.l problems. The developmen. of n.w medical techn.logies provides a better an. effective n.n.surgical treatmen. of acute MI an. in.reases lon.-term progn.sis in.this category of patien.s. The study aims to in.estigate the in.luen.e of hyperbaric oxygen.tion.treatmen. on.clin.cal outcomes (survival rate an. recurren. myocardial in.arction.(rMI)) durin. the five-year period of mon.torin.. The study in.olved 697 patien.s who suffered from acute MI, havin. un.ergon. the stan.ard treatmen.. The patien.s were ran.omly divided in.o two groups: Group 1 (referen.e, n.= 363);Group 2 (test, n.= 334). Patien.s of Group 2 were given.the tradition.l treatmen., accompan.ed with HBOT (isopression.for forty min.tes at a workin. pressure of 0.03 MPa). HBOT was applied first through the fifth day followin. MI. The treatmen. course in.luded six cycles, on.e per day. The clin.cal assessmen. was focused on.clin.cal outcome: rMI an. mortality related to cardiovascular even.s. HBOT application.that accompan.ed the acute MI with tradition.l pharmacotherapy has been.proved to reduce rMI within.five years followin. in.atien. discharge (rMI rate was 14% in.the referen.e group an. 5.4% in.the test group, χ2 = 13.3, р n.tion.of HBOT with tradition.l methods in.treatin. acute MI makes it possible to raise the five-year survival rate from 84.4% up to 95.9%.
