储层渗透率对天然气开采的影响

为全面了解储层渗透率对天然气开采的影响,以我国某天然气气田为例,首先对该气田的基本情况进行简单介绍,根据国内外研究现状,对天然气储层的渗流机理进行分析,在此基础上,开展了储层渗透率对天然气开采的影响研究。研究表明：在进行天然气资源开发作业的过程中,稳产时间与采收率都与储层的渗透率呈现正比例关系,随着储层渗透率的逐渐提升,天然气开发的稳产时间将逐渐增加,能源的采收率也将逐渐提升,对于气田采收率的增值而言,与储层的渗透率之间将会成反比例关系,随着储层渗透率的逐渐提升,气田采收率的增值将逐渐减小,在储层渗透率相对较低时,渗透率对天然气开采的影响相对较大,在储层渗透率相对较高时,渗透率将对天然气开发产生严重影响。

水浴法制备形貌可控的一维ZnO纳米和微米棒

用一步或两步简单的化学溶液法,以醋酸锌为原料,六亚甲基四胺或三乙醇胺为催化剂在玻璃衬底上生长出不同形貌的纳米和微米ZnO棒.探讨了反应液的酸碱度和反应液浓度对生成的ZnO棒形貌的影响,并分析了其生长机制.随着溶液浓度的增加,棒的长度与直径比减小,同时玻璃衬底上生长的ZnO棒从无序分布趋于垂直于衬底平行取向分布.随着pH值的改变,棒的形状由在弱酸性溶液中的细长棒状变为在弱碱性溶液中的圆头对称短棒;当碱性增大到一定程度时,可以生成颗粒状.通过控制一定的酸碱度和溶液浓度,可以得到规则的六角ZnO棒状阵列.测量了样品的XRD和扫描电镜像,并对其发光性能进行了测量分析.其中规则有序六角棒的发光光谱表明峰值在530nm,半高宽为220nm,可能是Vo+的电子和价带中的空穴辐射复合所致.

Improving operation lifetime of OLED by using thermally activated delayed fluorescence as host

We fabricated organic light-emitting diodes (OLEDs) with the thermally activated delayed fluorescence (TADF) material of 4CzIPN, which show better stability compared with the 4,4’-Bis(carbazol-9-yl)biphenyl (CBP) based devices. The half lifetime of the device using 4CzIPN as host material has doubled, and a slower voltage rise compared with that of CBP-based devices has been achieved, which indicates the improvement of stability. We attribute the better stability to the good film morphology and difficult crystallization property of 4CzIPN. Our results suggest that employing the 4CzIPN as host material can be a promising way of fabricating OLEDs with longer operation lifetime.     

Co-doping method used to improve the charge transport balance in solution processed OLEDs

In this paper, co-doping method is used to improve the current efficiency of solution-processed organic light-emitting diodes (OLEDs). By changing the ratio of two thermally activated delayed fluorescent (TADF) emitters, we studied the performance of device and its mechanism. A solution processed OLED with a structure of indium tin oxide (ITO, 150 nm)/PEDOT:PSS (30 nm)/CBP:4CzIPN-x%:4CzPN-y% (30 nm)/TPBi (40 nm)/LiF (1 nm)/Al (100 nm) was fabricated. The current efficiencies of 26.6 cd/A and 26.4 cd/A were achieved by the devices with dopant ratio of 6% 4CzIPN:2% 4CzPN and 2% 4CzIPN:6% 4CzPN in emitting material layer (EML), respectively. By investigating the tendency of current density change in devices with different doping ratio, we suggested that the enhancement of the current efficiency should be due to the charge transport balance improvement induced by assist dopant in EML.     

Improved performance of CdSe/ZnS quantum dot light-emitting diodes through doping with small molecule CBP

The poor film formation of CdSe/ZnS quantum dots (QDs) during spin-coating makes a substantial impact on the device performance of quantum dot light-emitting diodes (QLEDs). This work proposes a method to improve the morphology of the quantum dot light-emitting layer (EML) by adding small organic molecular 4,4''-Bis(9H-carbazol-9-yl) biphenyl (CBP) into the layer. Its surface roughness reduces from 6.21 nm to 2.71 nm, which guarantees a good contact between hole transport layer (HTL) and EML. Consequently, the CdSe/ZnS QDs:CBP based QLED achieves maximum external quantum efficiency (EQE) of 5.86%, and maximum brightness of 10 363 cd/m2. It is demonstrated that the additive of small organic molecules could be an effective way to improve the brightness and the efficiency of QLEDs.
