基于Mono Trap方法对酱油气味活性成分的分析

采用固相萃取整体捕集剂(monolithic material sorptive extraction,Mono Trap)结合热脱附、气相色谱-嗅闻-质谱(GC-O-MS)联用技术对高盐稀态酿造酱油气味活性成分进行提取分析.应用正交试验对Mono Trap方法中捕集剂的类型、萃取时间、萃取温度进行了优化,确定优化萃取条件为Mono Trap类型RGC18-TD、萃取时间60 min、萃取温度50℃.这一条件下能最大程度萃取吸附样品中的气味活性化合物,实验整体准确度和重复性良好.采用Mono Trap-GC-O-MS和SPME方法对高盐稀态酿造酱油气味活性化合物进行分析和比较,Mono Trap方法共鉴定出气味活性化合物56种,包括醇类9种、酮类5种、醛类7种、酯类9种、呋喃类6种、酚类3种、吡嗪类10种、有机酸类2种、含硫化合物4种、其他化合物1种;而SPME方法检测到55种气味活性化合物,且富集到的物质含量低于Mono Trap方法.与SPME方法相比,Mono Trap方法具有萃取量大、操作简便、回收率高等特点,在酱油的气味成分萃取上具有一定优势,有望成为今后酱油气味活性成分分析的研究方法之一.

运用含油气系统的研究方法明确了焉耆盆地勘探思路,指出焉耆盆地博湖坳陷可划分出北部凹陷及南部凹陷两个含油气系统,二者形成的关键时刻均出现在新生代,与侏罗系煤系烃源岩二次生烃密切相关,北部凹陷含油气系统各地质要素和作用的匹配优于南部凹陷含油气系统;目前发现的油气藏均为与小型断裂有关的复式油气藏,由于较大型断裂对油气保存不利,且含油气系统油气就近运移油气藏集中于生油窗内及其边缘,所以下一步的勘探应注意含油气系统生油窗边界地区的岩性圈闭和与小型断裂有关的复式圈闭。     

Nano-engineering of hybrid organic heterojunctions with carbon nanotubes to improve photovoltaic performance

Organic–inorganic hybrid photovoltaics are beginning to show significant promise as a low cost highly efficient route towards renewable energy generation. Of the hybrid architectures available, carbon nanotube incorporated organic photovoltaics is considered to be among the most promising. Herein, the optical and electronic effects of localizing multiwalled carbon nanotubes in the donor polymer is investigated in comparison to its incorporation into the bulk heterojunction architecture (triple heterojunction scheme) through photoluminescence quenching and dark diode characteristics analysis. A significant improvement in photoluminescence quenching is observed when the nanotubes are localized in the donor polymer where the active layer is formed through a sequential deposition route in comparison to the triple heterojunction scheme. However, the former architecture also leads to a higher recombination of carriers due to the introduction of trap states as observed through space charge limited conduction analysis. In comparison, the triple heterojunction scheme shows a lower dark current and hence a significantly improved photovoltaic device performance (3.8% in comparison to 2.6% for the sequentially deposited architecture). This indicates that the formation of the triple heterojunction is the more ideal scheme for improving device performances in organic–inorganic hybrid architectures.

Origin of enhanced electrical and conducting properties in pentacene films doped by molybdenum trioxide

Molybdenum trioxide (MoO₃) doped organic semiconductors have shown attractive applications in organic electric devices. The authors carried out an investigation on the origin of enhanced photoelectric characteristics in MoO₃-doped pentacene films. Electrical properties including charge transport, trap density and conductivity in bulk MoO₃-doped pentacene films were investigated through fundamental measurements of current-voltage characteristics. Electrical structure and conducting mechanism in MoO₃-doped pentacene films were further evaluated by X-ray diffraction and X-ray photoelectron spectroscopy measurements. The experimental results suggest that the improved conductivity in MoO₃-doped pentacene film was partly associated with the increased ratio of low Mo oxidation state (Mo⁴⁺) with a fact of better conducting property of MoO₂ than that MoO₃.     

利用相邻地震反射能量组合特征排除“亮点”陷阱——以川西坳陷德阳向斜为例

川西坳陷内中浅层岩性气藏勘探中,地震振幅亮点异常是储层识别的重要依据,但越来越多的钻井证实“亮点”异常,也可能是泥岩、薄互层、致密砂体等众多非储层带来的陷阱。以川西坳陷德阳向斜内,典型完钻井井震分析为基础,总结出不同物性砂体地震响应特征,建立起“顶部强波谷、底部强波峰”、相邻波峰反射能量“上弱下强”的优质储层识别模式,同时利用相邻波峰反射能量“上强下弱,双强”等特征来排除振幅“亮点”陷阱,提高基于地震反射能量的储层预测精度,该方法具有简单、直观,易实现等特征,同时经钻井证实,预测结果准确可靠。
